VNFIBER ® Polyester Staple Fiber is able to substitute virgin fibers and provides advanced solutions in a wide range of applications for Cotton and Modified Cotton Spinning Systems and for Stock Dyeing.


  • Hollow fibers between 7-14 dtex, normal and siliconized;
  • Hollow spiral siliconized (HCS) and non siliconized (including slick type) of 7-14 dtex, white or colored;
  • Solid staple fibers in the range of 1.3 - 30 dtex , different colors: white (semi-dull, optical white in two shades, super-white) and colored (natural colors and dope dyed);

Polyester Fibers and Yarns

Polyester fibers are produced by a melt-spinning process. The raw materials are heated to a spinning mass, which is then pressed through spinnerets (similar to a sieve). Manufacturing techniques have developed to the point where they can produce round, oval or angular profiles, making them firm to the touch.

Polyester fibers are particularly resistant to light and weather, and can withstand climatic effects, being as light or as fine as the weather demands. Polyester fibers are also capable of dissipating moisture and drying quickly.

We are a professional manufacturer of polyester filament (POY, SDY, DTY) yarns, and specialize in producing high-quality filament yarns with various functionalities.

Polyester fibers are most commonly used for apparel, from sportswear to high fashion; home textiles, such as bedding and carpets; non-woven materials including surgical gowns; technical textiles such as filters; and automotive uses including carpets and insulation.


Bicomponent Fibers

Bi-component fibers can be defined as “extruding two polymers from the same spinneret with both polymers contained within the same filament.” A close relative is “co-spun fiber,” which is a group of filaments of different polymers, but with a single component per filament spun from the same spinneret.

The term “conjugate fibers” is often used, particularly in Asia, as synonymous with bicomponent fibers. The main objective of producing bicomponent fibers is to exploit capabilities which do not exist in either polymer alone.

Bicomponent fibers made of polyethylene sheath and polypropylene core are important fibers for the nonwoven fabric market.
