ES BI-component Fiber (PP/PE Low Melting Fiber)

Baby/Lady/ Oldman Diaper
Hygiene/Medical Application
Non-woven fabric

ES fiber was first developed by Japan CHISSO Corp and is a new type of polyolefin composite fiber. It has a sheath-core structure. The sheath has a low melting point and good flexibility, and the core has a high melting point and high strength. After heat treatment, the skin is partially melted to play a role in adhesion. At present, the fiber is mainly used for hot-air nonwoven used in sanitary materials, warm filling materials, filter materials and other fields.

ES fiber on the market is mainly divided into PE/PP and PE/PET based on raw materials, and the product specification is mainly 1.5-6D.

The surge of ES fiber has a close relation to face mask which is hotspot product now on the market due to coronavirus pandemic. ES fiber is mainly used for hot-air nonwoven usually used in baby diapers and female hygiene products, and only a small part is used for N95 face mask.


ES FIBER PRODUCTION LINE

 

POLYESTER LOW MELT FIBER(COPET/PET BI-COMPONENT FIBER)

Low Melting Bonding Fiber:

  • Low Melting Bonding Fiber
  •  LMF, which is produced by bicomponent spinning of general polyester and modified polyester, can be melted at lower temperature(110~200℃) than normal fiber and bonded with other fibers.
  •  Excellent Bonding Properties
  • LMF provides diverse melting points generated through controlling seath part (modified polyester).
  • Excellent Durability
  • The bonding strength after being combined with other fibers hold out semipermanently.
  • Easy Mixing Properties with other Fibers
  • Homogeneous properties between LMF and various Fibers make blending easy on line.
  • Excellent Resilience
  • The formation of non-woven fabric made with LMF is simple and excellent.

Applications:

  • Autumotive Use (Car-Interior, Doortrim)
  • Bedding (Mattress, Quilting, Padding)
  •  Industrial Use (Engineering Material, Construction Material Soundproofing, Insulation, Filter)
  • Hygienic Materials (Hygienic Bonding, Clothing)

POLYPHENYLENE SULFIDE (PPS) FIBER 

The full name of polyphenylene sulfide is polyphenylene sulfide. It is a thermoplastic resin with a phenylsulfide group in the main chain of the molecule. Polyphenylene sulfide is a crystalline polymer. The undrawn fiber has a large amorphous zone (crystallinity is about 5%), crystallization exotherm occurs at 125°C, the glass transition temperature is 150°C, and the melting point is 281°C. The drawn fiber produced partial crystallization during the drawing process (increased to 30%). For example, heat treatment of the drawn fiber at a temperature of 130-230°C can increase the crystallinity to 60-80%. Therefore, the drawn fiber has no obvious glass transition or crystallization exotherm, and its melting point is 284°C. With the increase of crystallinity after stretching and heat setting, the density of fiber also increases correspondingly, from 1.33g/cm3 before stretching to 1.34g/cm3 after stretching, and it can reach 1.38g/cm3 after heat treatment. Molding shrinkage: 0.7% Molding temperature: 300-330℃.

PPS is a special engineering plastic with excellent comprehensive performance. PPS has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, balanced physical and mechanical properties, dimensional stability, and excellent electrical properties. It is widely used as a structural polymer material. It is widely used after filling and modification. Used as special engineering plastics. At the same time, it can also be made into various functional films, coatings and composite materials, which have been successfully applied in the fields of electronics, aerospace, and automobile transportation.
