Fiber material and PSF, Polyester filament, VSF Price week data(Week 14)

As the oil continue to rebounded, Polyester chip,PSF, filament yarn price continued to rose on Saturday and Sunday in domestic market. While the export demand is still weak.

Please check the updated market trend of Week 14

Data this week – W14

Market this week – W14

Summary: Oil went down, PTA narrowed, MEG fluctuated to fell, Polyester chip, PSF followed to go down, Polyester filament accelerated to fell, VSF weak stable.

1,Oil prices rose sharply this week. As many cities around the world have announced quarantine regulation, consumer demand for gasoline continues to decline, and oil prices continued to decline on Monday. In hopes of a new agreement that the Russian Kremlin and Washington may be able to reach to replace the consensus reached at the meeting of OPEC and its allies, oil prices rose on Tuesday. The new COVID-19 epidemic continues to impact the demand for crude oil. The joint oil production reduction plan of major oil-producing countries has not been reached as scheduled. The oil price war in Russia continues. The international crude oil market is under double pressure from supply and demand. US President Trump said he had talks with Russian President Vladimir Putin and the Saudi Crown Prince, and the two countries are expected to reduce production by about 10 million barrels. This remark pushed US crude oil prices up by 24% on Thursday, the highest single-day increase in history.

2,The PTA rebounded after a low volatility, the spot price rebounded and the trading volume rose sharply. At the beginning of the week, PTA equipment was intensively restarted, and PTA supply was abundant. Under the pressure of polyester factory inventory, some factories reduced production and the buying atmosphere was weak. In the second half of the week, crude oil rebounded from a low level, the sales volume increased, and traders bought aggressively.

3,MEG prices rose sharply this week, and buying followed up positively. At the beginning of the week, MEG prices were sorted in a narrow range, with base trades mainly, and individual polyester factories participated. In the middle of the week, as the crude oil market boosted and market sentiment boosted, MEG prices rose sharply and volume increased.

4,The polyester chip market gradually stopped falling and stabilized. Continued downwards on the cost side. The market continued to decline in the first half of the week. Chip prices continued to record lows, but entered the second half of the week. Stimulated by the news, crude oil profits rose and polyester raw materials began to rebound. The market sentiment has been greatly improved. After the transaction volume has increased, prices have gradually increased, and the atmosphere of market bottoming is obvious. The trading volume is concentrated in the second half of the week.

5,Jiangsu and Zhejiang polyester filament yarn restrain first and then rise. At the beginning of the week, as raw materials continued to plunge, the polyester yarn also followed a decline. Due to the high inventory of some silk mills, the preferential margin is large in order to promote transactions. Overall, the transaction price of the entire market is confusing. In the middle of the week, as raw materials rose, the terminal’s willingness to purchase at low-priced was strong, and production and sales ushered in heavy volume. The prices in South China were lowered at the beginning of the week and followed the rise in the middle of the week. In the export market, quotations continued to decline due to the severe foreign epidemic situation, but the demand side has not improved.

6,Polyester staple fiber stopped falling and quotations were raised. In the first half of the week, the PSF maintained a downward trend, and most of the factories mainly engaged in negotiating operations, and turnover fell. Afterwards, driven by the rebound of crude oil and polyester raw materials, the PSF transaction volume was increased significantly on Thursday and Friday. However, most of the purchases are mainly from the replenishment of yarn mills, and traders have less operations. The overall inventory of the factory is at a normal level, and there is still a small amount of previous orders due to lower parts.

7,Viscose staple fiber weakened, and sales volume did not improve much. The quotation is slightly lowered, the actual transaction can be negotiated specifically, but a large number of transactions have not been heard. High-white fibers tended to be calm this week, and other differentiated fibers did not perform well. Export orders have partially increased.

Nonwoven Processes and Applications(MELT BLOWN NON-WOVEN)

ABSTRACT


Melt-blown process is a one-step process in which high-velocity air blows a molten thermoplastic resin from an extruder die tip onto a conveyor or take-up screen to form a fine fibrous and self-bonding web. The fibres in the melt blown web are laid together by a combination of entanglement and cohesive sticking. The ability to form a web directly from a molten polymer without controlled stretching gives melt blown technology a distinct cost advantage over other systems. Melt blown webs offer a wide range of product characteristics such as random fibre orientation, low to moderate web strength. About 40% of melt blown material is used in the uncombined (monolithic) state. The remainder of melt blown materials are composites or laminates of melt blown webs with another material or nonwoven. The largest end-uses for monolithic melt blown materials are oilsorbents, air and liquid filtration media.

INTRODUCTION

The melt blown process is a unique among nonwoven systems. Fundamentally it is a high tech version of the making of cotton candy at amusement parks. In making cotton candy, sugar is melted and pressure fed through small openings in a rotary spinning wheel. Upon exciting, the molten sugar congeals and is stretched into short fibres by centrifugal forces. In the melt blown system, molten polymers are forced through small slit openings and high temperature (230oC-390oC) air is impinged (300-500 miles/hr) at both sides of the exiting film. The fast-moving air streams effectively stretch or attenuate the molten polymer by multiple orders of magnitude and solidify it into a random array of discontinuous subdenier fibers. The fibers are then condensed (separated from the air stream) as a randomly entangled web and compressed between heated rolls. This paper deals with manufacturing technology, type of polymers used, web characteristics, properties and its various applications.

1. Process Description

A typical melt blowing process consists of the following elements: extruder, metering pumps, die assembly, web formation, and winding.

1.1. Extruder

The polymer pellets or granules are fed into the extruder hopper. Gravity feed supplies pellets to the screw, which rotates within the heated barrel. The pellets are conveyed forward along hot walls of the barrel between the flights of the screw, as shown in Figure 2. As the polymer moves along the barrel, it melts due to the heat and friction of viscous flow and the mechanical action between the screw and barrel. The screw is divided into feed, transition, and metering zones. The feed zone preheats the polymer pellets in a deep screw channel and conveys them to the transition zone. The transition zone has a decreasing depth channel in order to compress and homogenize the melting polymer. The molten polymer is discharged to the metering zone, which serves to generate maximum pressure for extrusion. The pressure of molten polymer is highest at this point and is controlled by the breaker plate with a screen pack placed near the screw discharge. The screen pack and breaker plate also filter out dirt and infused polymer lumps. The pressurized molten polymer is then conveyed to the metering pump.

1.2. Metering pump

The metering pump is a positive-displacement and constant-volume device for uniform melt delivery to the die assembly. It ensures consistent flow of clean polymer mix under process variations in viscosity, pressure, and temperature. The metering pump also provides polymer metering and the required process pressure. The metering pump typically has two intermeshing and counter-rotating toothed gears. The positive displacement is accomplished by filling each gear tooth with polymer on the suction side of the pump and carrying the polymer around to the pump discharge, as shown in Figure 2. The molten polymer from the gear pump goes to the feed distribution system to provide uniform flow to the die nosepiece in the die assembly (or fiber forming assembly).

1.3. Die Assembly

The die assembly is the most important element of the melt blown process. It has three distinct components: polymer-feed distribution, die nosepiece, and air manifolds.

1.3.1. Feed Distribution

The feed distribution in a melt-blown die is more critical than in a film or sheeting die for two reasons. First, the melt-blown die usually has no mechanical adjustments to compensate for variations in polymer flow across the die width. Second, the process is often operated in a temperature range where thermal breakdown of polymers proceeds rapidly. The feed distribution is usually designed in such a way that the polymer distribution is less dependent on the shear properties of the polymer. This feature allows the melt blowing of widely different polymeric materials with one distribution system. The feed distribution balances both the flow and the residence time across the width of the die. There are basically two types of feed distribution that have been employed in the melt-blown die: T-type (tapered and untapered) and coat hanger type. Presently, the coathanger type feed distribution is widely used because it gives both even polymer flow and even residence time across the full width of the die.

1.3.2. Die Nosepiece

From the feed distribution channel the polymer melt goes directly to the die nosepiece. The web uniformity hinges largely on the design and fabrication of the nosepiece. Therefore, the die nosepiece in the melt blowing process requires very tight tolerances, which have made their fabrication very costly. The die nosepiece is a wide, hollow, and tapered piece of metal having several hundred orifices or holes across the width. The polymer melt is extruded from these holes to form filament strands which are subsequently attenuated by hot air to form fine fibers. In a dies nosepiece, smaller orifices are usually employed compared to those generally used in either fiber spinning or spunbond processes. A typical die nosepiece has approximately 0.4-mm diameter orifices spaced at 1 to 4 per millimeters (25 to 100 per inch). There are two types of die nosepiece used: capillary type and drilled hole type. For the capillary type, the individual orifices are actually slots that are milled into a flat surface and then matched with identical slots milled into a mating surface. The two halves are then matched and carefully aligned to form a row of openings or holes as shown in Figure 3. By using the capillary type, the problems associated with precise drilling of very small holes are avoided. In addition, the capillary tubes can be precisely aligned so that the holes follow a straight line accurately. The drilled-hole type has very small holes drilled by mechanical drilling or electric discharge matching (EDM) in a single block of metal, as shown in Figure 3. During processing, the whole die assembly is heated section-wise using external heaters to attain desired processing temperatures. It is important to monitor the die temperatures closely in order to produce uniform webs. Typical die temperatures range from 2l5oC to 340OC.

1.3.3. Air Manifolds

The air manifolds supply the high velocity hot air (also called as primary air) through the slots on the top and bottom sides of the die nosepiece, as shown in Figure 4. The high velocity air is generated using an air compressor. The compressed air is passed through a heat exchange unit such as an electrical or gas heated furnace, to heat the air to desired processing temperatures. They exits from the top and bottom sides of the die through narrow air gaps, as shown in Figure 4. Typical air temperatures range from 230oC to 360oC at velocities of 0.5 to 0.8 the speed of sound.

1.4. Web Formation

As soon as the molten polymer is extruded from the die holes, high velocity hot air streams (exiting from the top and bottom sides of the die nosepiece) attenuate the polymer streams to form microfibers. As the hot air stream containing the microfibers progresses toward the collector screen, it draws in a large amount of surrounding air (also called secondary air) that cools and solidifies the fibers, as shown in Figure 4. The solidified fibers subsequently get laid randomly onto the collecting screen, forming a self-bonded nonwoven web. The fibers are generally laid randomly (and also highly entangled) because of the turbulence in the air stream, but there is a small bias in the machine direction due to some directionality imparted by the moving collector. The collector speed and the collector distance from the die nosepiece can be varied to produce a variety of melt-blown webs. Usually, a vacuum is applied to the inside of the collector screen to withdraw the hot air and enhance the fiber laying process.

1.5. Winding

The melt-blown web is usually wound onto a cardboard core and processed further according to the end-use requirement. The combination of fiber entanglement and fiber-to-fiber bonding generally produce enough web cohesion so that the web can be readily used without further bonding. However, additional bonding and
finishing processes may further be applied to these melt-blown webs.

1.6. Bonding

Additional bonding, over the fiber adhesion and fiber entanglement that occurs at lay down, is employed to alter web characteristics. Thermal bonding is the most commonly used technique. The bonding can be either overall (area bonding) or spot (pattern bonding). Bonding is usually used to increase web strength and abrasion resistance. As the bonding level increases, the web becomes stiffer and less fabriclike.

1.7. Finishing

Although most nonwovens are considered finished when they are rolled up at the end of the production line, many receive additional chemical or physical treatment such as calendering, embossing, and flame retardance. Some of these treatments can be applied during production, while others must be applied in separate finishing operations.


Other Processes for Melt blown Production of Non-woven.

2. Process Variables

The process variables can be divided into two categories : a) operational variables and b)material variables. By manipulating operational and material variables one can produce a variety of meltblown fabrics with desired properties. Each of these variables play a significant role in process economics and product reliability.

2.1. Operational variables

This can be classified as: a) on-line and b) off-line variables. The on-line variables are those which can be changed according to requirements during production. The polymer throughput rate, air throughput rate, polymer/die temperatures, air temperature and die-to-collector distance are the five basic on-line operational variables. These variables are easy to change and dictate the major fabric properties.

The polymer and air throughput rates basically control the final fiber diameter, fiber entanglements and the extent of zone of attenuation.

The polymer/die and air temperatures in conjunction with air flow rate affect the appearance and hand of the fabric, fabric uniformity and fabric defects in the production.

The die-to-collector distance generally affects the openness of the fabric and fiber-to-fiber thermal bonding. The fiber diameter increases slightly with increase in die-to-collector distance.

The offline processing variables are those variables which can only be changed when production line is not in operation, such as die hole size, die set-back, air gap, air angle, web collection type and polymer/air distribution. Most of the offline process variables are set for particular product line.

The die hole size, die design parameters and die set-back are believed to affect the fiber size. The die hole size should be large enough to pass the polymer melt without plugging. The back pressure generated by the polymer feed distribution typeand the ratio of orifice length to diameter should be high enough to give good
distribution and controllable flow of the polymer melt.

The air gap affects the air exit pressure and is also believed to affect the degree of fiber breakage.

2.2. Material Variables

The material variables include the polymer type, molecular weight, molecularweight weight distribution, polymer additives, polymer degradation and polymer forms.

Basically, any fiber-forming polymer that can give an acceptably low-melt viscosity at a suitably processing temperature and can solidify before landing on the collector screen ca be melt blown into fine-fibered webs. Some of the processed polymers are :

Polypropylene is easy to process and makes good web.

Polyethylene is more difficult to melt-blow into fine fibrous webs than is polypropylene. Polyethylen is difficult to draw because of its melt elasticity.

PBT processes easily and produces very soft, fine-fibered webs.

Nylon 6 is easy to process and makes good webs.

Nylon 11 melt-blows well into webs that have very unusual leather like feel.

Polycarbonate produces very soft-fiber webs.

Polystyrene produces an extremely soft, fluffy material with essentially no shot defects.

Usually polymer in pellet form is used for processing, but the present trend is to use polymer granules. It is beloved that the granules melt faster and give a more even heat distribution.

The melt blown process requires low molecular weight and narrow molecular weight distribution resins to produce uniform fine-fibered webs.

3. Web Characteristics and Properties

3.1. Uniformity


The uniformity of the web is controlled by two important parameters: uniform distribution of fiber in the air stream and proper adjustment of the vacuum level under the forming wire or belt. Non-uniform distribution of fiber in the air stream can result from poor die design and from non-uniform ambient airflow into the air stream. The vacuum under the forming media should be adjusted to pull the total air stream through the media and lock the fibers in place. Generally, the closer the die is to the forming drum or belt, the better the web uniformity.

5.1. Filtration media

This market segment continues to be the largest single application. The best known application is the surgical face mask filter media. The applications include both liquid filtration and gaseous filtration. Some of them are found in cartridge filters, clean room filters and others.

5.2. Medical fabrics

The second largest meltblown market is in medical/surgical applications. The major segments are disposable gown and drape market and sterilization wrap segment.

5.3. Sanitary products

Meltblown products are used in two types of sanitary protection products feminine sanitary napkin and disposable adult incontinence absorbent products.

5.4. Oil adsorbents

Melt blown materials in variety of physical forms are designed to pick up oily materials. The best known application is the use of sorbents to pick up oil from the surface of water, such as encountered in an accidental oil spill.

5.5. Apparel

The apparel applications of melt-blown products fall into three market segments: thermal insulation, disposable industrial apparel and substrate for synthetic leather. The thermal insulation applications takes advantage of microvoids in the structure filled with quiescent air, resulting in excellent thermal insulation.

5.6. Hot-melt adhesives

The melt-blown process has a special feature: it can handle almost any type of thermoplastic material. Thus, the task of formulating a hot-melt adhesive to provide specific properties can be greatly simplified by using the melt blown system to form the final uniform adhesive web.

5.7. Electronic specialties

Two major applications exist in the electronics specialties market for melt blown webs. One is as the liner fabric in computer floppy disks and the other as battery separators and as insulation in capacitors.

5.8. Miscellaneous applications

Interesting applications in this segment are manufacture of tents and elastomeric nonwoven fabrics which have the same appearance as continuous filament spunbonded products.

CONCLUSION

The melt blown technique for making nonwoven products has been forecast in recent years as one of the fastest-growing in the nonwovens industry. With the current expansion and interest, it cannot be questioned that meltblown is well on its way to becoming one of the major nonwoven technologies. Technical developments are also on the horizon that will increase the scope and utility of this technology. The application of speciality polymer structures will no doubt offer new nonwoven materials unobtainable by other competitive technologies. So a strong and bright future be forecasted for this technology.

Should You Wear a Surgical Mask? These Are the Latest Guidelines

UPDATE (April 4, 2020): The U.S. Centers for Disease Control and Prevention (CDC) has updated its recommendations regarding the general public wearing face masks during the coronavirus outbreak and subsequent COVID-19 pandemic. While it still does not recommend wearing surgical masks or N95 respirators, it now supports “wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies) especially in areas of significant community-based transmission.”

The reasoning behind this new recommendation, the CDC website says, is because recent studies indicate that a high number of individuals with the novel coronavirus are asymptomatic and that the virus can be transmitted to others before symptoms become apparent. By wearing a cloth mask, you add an extra layer of protection between yourself and others when you may be speaking, coughing, or sneezing.

It is important to note that wearing a mask does not erase the need to adhere to social distancing guidelines. “It is critical to emphasize that maintaining six-feet social distancing remains important to slowing the spread of the virus,” the CDC website says. Additionally, according to NPR, as of an April 4 briefing of the coronavirus task force, the White House has urged people to stay at home as much as possible, especially over the next two weeks — including foregoing trips to the grocery store and pharmacy, if possible. These masks are protective measures for others during any essential runs when you absolutely have to leave the house, rather than excuses to leave the house.

“The next two weeks are extraordinarily important,” said Deborah Birx, the White House’s coronavirus response coordinator. “This is the moment to not be going to the grocery store, not going to the pharmacy, but doing everything you can to keep your family and your friends safe and that means everybody doing the 6-feet distancing, washing their hands.”

This post originally appeared on February 4, 2020:

This week, the CDC confirmed the first case of person-to-person transmission of the coronavirus, which has already killed 170 people in China, where the virus originated. While the CDC says it expects more cases, including the potential for more person-to-person spread, experts are encouraging the general public to take evidence-based prevention measures — which doesn’t include wearing surgical masks.

According to Nancy Messonnier, director of the Center for the National Center for Immunization and Respiratory Diseases, the CDC doesn’t currently recommend the use of face masks for the general public.

“The virus is not currently spreading in the general community. While it is cold and flu season, we don’t routinely recommend the use of face masks by the public to prevent respiratory illness,” Messonnier stated in a telebriefing on January 30.

Instead, the CDC and other experts encourage the public to focus on more common practices — like handwashing and covering coughs — to prevent the spread of infection.

Why you don’t need to buy a surgical mask for coronavirus

Neha Nanda, medical director of infection prevention and antimicrobial stewardship at Keck Medicine of USC, says there are two major reasons not to rush out and buy a mask right now. First, the risk of contracting the coronavirus in the United States is currently low, assuming you’re not in direct contact with someone who may be infected.

Second, masks aren’t generally used for protecting yourself from an illness. “When we wear a mask, what we are doing is containing our secretions [to keep them] from getting to the person we are in contact with,” she says. “This is so the people who come close to you don’t get infected.”

Even if you’re physically near someone who might be infected with coronavirus, Nanda says you would have to be very close to catch it. “I would only wear the mask if I would be in proximity to another person in a small, closed room,” she says. “But you have to be very close to be infected. With the novel coronavirus, it’s within two meters.”

According to Yvonne Maldonado, an infectious disease physician at Stanford Health Care, masks can provide a basic barrier, but they’re not meant to be used for long periods of time.

“When you’re in public, the mask is only meant to be a simple barrier,” she says. “It will mostly keep you from inhaling large droplets for a short period, and keep you from touching your face, which is another way you inoculate organisms into your body.”

Another potential issue with surgical masks: Once they get moist from your breath, they don’t work. “They’re not really helpful after about five minutes since we inhale and exhale humid air, which dampens the mask so it loses its effectiveness,” says Maldonado. “If something lands on the mask when it’s moist, it will get absorbed.”

If you’re sick and want to protect others from catching what you have, wearing a surgical mask in public, especially in an enclosed area, could be an effective way to keep your illness to yourself.

“If you’re sitting in a waiting room, at least for that short period of time you’re in transit [the mask] will be dry and you’ll be able to keep yourself from coughing large droplets onto other people,” says Maldonado.

How to protect yourself from coronavirus

If you’re concerned about catching coronavirus — or any virus — the CDC’s current recommendations include avoiding contact with anyone you know who might be sick and practicing routine handwashing.

“It’s surprising how something so simple as handwashing really makes a difference,” Maldonado says. “Studies and experience show that when people wash their hands consistently the rates of disease really drop.”

Oerlikon Nonwoven Large-Scale Meltblown Sold To Asia: Shortens Delivery Times Due To Rising Demand For Meltblown Systems

April 2, 2020

NEUMÜNSTER, Germany — April 2, 2020 — A large-scale Asian manufacturer of manmade fibers and polymers has invested in a new Oerlikon Nonwoven meltblown system. The recently-signed contract comprises a 2-beam system for manufacturing filtration nonwovens – predominantly for medical products such as face masks – with a nominal capacity of up to 1,200 tons of nonwovens a year. The commercial production launch has been scheduled for the fourth quarter of 2020.

The 2-beam system has an operating width of 1.6 meters and is equipped with the new patented Oerlikon Nonwoven electro-charging unit. The Oerlikon Nonwoven meltblown technology is recognized by the market as being the technically most efficient method for producing highly-separating filter media made from manmade fibers, particularly in conjunction with electrostatic charging and with extremely low pressure loss. Electro-charging the filter nonwovens allows the manufacture of sophisticated EPA- and HEPA-class filter media as well as media that comply with the requirements of N95-, FFP2- and FFP3-class respiratory masks.

The demand for filtration nonwovens for medical applications has risen tremendously across the globe since the outbreak of the Sars-CoV-2 (coronavirus) epidemic, presenting all manufacturers with huge challenges. “We are currently receiving inquiries from all over the world for our system concepts”, explains Dr Ingo Mählmann, Vice President Sales & Marketing Oerlikon Nonwoven, talking about the current situation. “To improve the supply situation, we have changed our prioritization in favor of considerably shorter delivery times for meltblown systems, so that customers can now be supplied even faster and also with very short lead times.” A meltblown system will be commissioning at the site of a leading Western European nonwovens producers as early as the second quarter of 2020. This system will be deployed exclusively in the manufacture of nonwovens for respiratory masks.

Due to the current state of emergency with regards to the local supply of face masks, Oerlikon Nonwoven is currently using its own laboratory system to produce electrostatically-charged filter media which are being sent to local small businesses and companies for the manufacture of face masks. “We are thrilled to be making a contribution towards fighting the pandemic, particularly in the local vicinity of our production site in Neumünster”, adds Rainer Straub, Head of Oerlikon Nonwoven.

Melt Blown Process

Developments in manufacturing techniques for technical nonwovens

H.-G. Geus, in Advances in Technical Nonwovens, 2016

Melt blown

The melt blown process is a nonwoven manufacturing system involving direct conversion of a polymer into continuous filaments, integrated with the conversion of the filaments into a random laid nonwoven fabric. First developments in this field of technology in the industrial area started around 1945. The general process description is similar to the spunlaid process, but in detail, both types of processes are quite different. Using the melt blown technology, the spun filaments are accelerated by means of hot, fast-flowing air that is directly blown onto a moving substrate, creating a self-bonded web. Figs 5.5–5.8 show principles and sketches of the different melt blown technologies. The hot air temperature is close to the used melt temperature. The achieved filament diameter is one magnitude lower compared to the spunlaid process, 1–5 μm. The calculated filament speed out of throughput and measured filament diameter is resulting in filament speed higher than sonic speed. Since the used air geometries are not suitable to create supersonic speed, the air speed cannot the single source of forces for the downsizing of the filaments.

The addition of the forces out of the air speed for the downsizing of the filaments and out of drag forces created within the free air jet is typical for the melt blown process. This effect of combined forces results in a variation of filament diameters along the filaments, so the measured filament diameter distribution is relatively broad. Melt blown fabrics are mainly used for their barrier, filtration and their absorption properties.View chapterPurchase book

Crude Oil and FIber Market Trend Week 14

As the oil continue to rebounded, Polyester chip,PSF, filament yarn price continued to rose on Saturday and Sunday in domestic market. While the export demand is still weak.

Market this week – W14

Summary: Oil went down, PTA narrowed, MEG fluctuated to fell, Polyester chip, PSF followed to go down, Polyester filament accelerated to fell, VSF weak stable.

1,Oil prices rose sharply this week. As many cities around the world have announced quarantine regulation, consumer demand for gasoline continues to decline, and oil prices continued to decline on Monday. In hopes of a new agreement that the Russian Kremlin and Washington may be able to reach to replace the consensus reached at the meeting of OPEC and its allies, oil prices rose on Tuesday. The new COVID-19 epidemic continues to impact the demand for crude oil. The joint oil production reduction plan of major oil-producing countries has not been reached as scheduled. The oil price war in Russia continues. The international crude oil market is under double pressure from supply and demand. US President Trump said he had talks with Russian President Vladimir Putin and the Saudi Crown Prince, and the two countries are expected to reduce production by about 10 million barrels. This remark pushed US crude oil prices up by 24% on Thursday, the highest single-day increase in history.

2,The PTA rebounded after a low volatility, the spot price rebounded and the trading volume rose sharply. At the beginning of the week, PTA equipment was intensively restarted, and PTA supply was abundant. Under the pressure of polyester factory inventory, some factories reduced production and the buying atmosphere was weak. In the second half of the week, crude oil rebounded from a low level, the sales volume increased, and traders bought aggressively.

3,MEG prices rose sharply this week, and buying followed up positively. At the beginning of the week, MEG prices were sorted in a narrow range, with base trades mainly, and individual polyester factories participated. In the middle of the week, as the crude oil market boosted and market sentiment boosted, MEG prices rose sharply and volume increased.

4,The polyester chip market gradually stopped falling and stabilized. Continued downwards on the cost side. The market continued to decline in the first half of the week. Chip prices continued to record lows, but entered the second half of the week. Stimulated by the news, crude oil profits rose and polyester raw materials began to rebound. The market sentiment has been greatly improved. After the transaction volume has increased, prices have gradually increased, and the atmosphere of market bottoming is obvious. The trading volume is concentrated in the second half of the week.

5,Jiangsu and Zhejiang polyester filament yarn restrain first and then rise. At the beginning of the week, as raw materials continued to plunge, the polyester yarn also followed a decline. Due to the high inventory of some silk mills, the preferential margin is large in order to promote transactions. Overall, the transaction price of the entire market is confusing. In the middle of the week, as raw materials rose, the terminal’s willingness to purchase at low-priced was strong, and production and sales ushered in heavy volume. The prices in South China were lowered at the beginning of the week and followed the rise in the middle of the week. In the export market, quotations continued to decline due to the severe foreign epidemic situation, but the demand side has not improved.

6,Polyester staple fiber stopped falling and quotations were raised. In the first half of the week, the PSF maintained a downward trend, and most of the factories mainly engaged in negotiating operations, and turnover fell. Afterwards, driven by the rebound of crude oil and polyester raw materials, the PSF transaction volume was increased significantly on Thursday and Friday. However, most of the purchases are mainly from the replenishment of yarn mills, and traders have less operations. The overall inventory of the factory is at a normal level, and there is still a small amount of previous orders due to lower parts.

7,Viscose staple fiber weakened, and sales volume did not improve much. The quotation is slightly lowered, the actual transaction can be negotiated specifically, but a large number of transactions have not been heard. High-white fibers tended to be calm this week, and other differentiated fibers did not perform well. Export orders have partially increased.

BYD Shifts Production to Face Masks and Hand Sanitizer

Chinese electric vehicle maker responds to Covid-19 outbreak

Chinese electric vehicle (EV) maker BYD has announced it is operating the ‘world’s largest face mask plant’, less than a month after starting production in response to the COVID-19 outbreak.

The company, which is partially owned by Warren Buffett, said its factory can produce 300,000 bottles of hand sanitizer gels and five million face masks per day, equivalent to a quarter of China’s entire production capacity and claims it was able to begin mask production within seven days of deciding to launch production. It suggests the market would normally take 15 to 30 days to manufacture a mask-producing machine and start output.

BYD is shipping its medical-grade hand sanitizers to medical staff in hospitals and agencies across China.

Sherry Li, Director General of BYD’s President Office, says, “A production line for high-quality face masks requires about 1300 parts for various gears, chains, and rollers, 90% of which are BYD’s self-made parts.”

Zhao Jianping, General Manager of BYD’s Quality Division, said: “The equipment that we already have offers precision and quality that is much higher than what is commonly required to produce masks.”

Last year BYD sold more than 113,000 plug-in EVs worldwide and currently has nearly 40,000 electric buses in service around the world.

Sinopec Diversifies into Meltblown

Sinopec Diversifies into Meltblown

Apr 01, 2020 www.nonwovens-industry.com

In early March, Sinopec Corp, China’s leading energy and chemical company, put its first meltblown nonwovens  line into operation at its Yanshan factory in Beijing . The Yanshan factory is a converted 3600 M2 old warehouse that has found new life as a global production base following the challenges brought by the coronavirus outbreak.

The 14,400 ton capacity Yanshan facility is one of Sinopec’s two meltblown nonwoven fabric assembly bases and is co-managed with China National Machinery Industry Corporation. The base has two nonwoven production lines and three spunbond production lines and can produce up to four tons of meltblown fabric for 1.2 million N95 disposable masks or six tons for six disposable masks per day. 

The new facility also takes advantage of Sinopec’s integrated upstream supply-chain by sourcing local materials from Yanshan and support from the on-site synthetic resin production line. 

“It normally takes about half a year to complete the construction of a 10,000-ton meltblown fabric factory – We have done it in 12 days, 48 hours ahead of schedule. In a challenging time like this, saving 48 hours means that we can produce an extra 12 million disposable masks,” says Lv Dapeng, spokesperson of Sinopec Corp.

The largest medical material supplier in China, Sinopec is a significant supplier of polypropylene, a key component in the production of disposable masks for medical use. The new assembly line will ensure a stable supply of medical supplies, such as masks and clothing, can be distributed across the nation and worldwide. 

“We are privileged to support those who are protecting us from the virus. Sinopec will utilize all of our resources to ensure supplies to the frontline are guaranteed,” says Dapeng. 

Sinopec’s other eight meltblown nonwoven   lines in Yizheng, Jiangsu are currently under construction and are expected to enter operational by mid-April.
