Classification of differential fiber varieties

Differentiation chemical fiber refers to conventional synthetic fiber with innovation or some special features. There is a lot kinds of differential fiber, which are mainly used for clothing and decorative fabrics.

First, divided from the morphology, differential fibers include profiled fiber, hollow fiber, composite fiber and fine (denier) fiber. Profiled fiber is chemical fiber spinned through a spinneret with certain geometric shape (non-circular) hole and has special cross section. Hollow fiber has a tubular cavity through the axis of fiber. Composite fiber is composed of two and more than two polymers or the same polymer with different properties, which is spinned by bicomponent spinning. Fine (denier) fiber has lower monofilament linear density and also known as micro-fiber.

Second, divided from the physical and chemical properties, differential fibers include anti-static fiber, high shrinkage fiber, flame-retardant fibers, anti-gigging-pilling fibers and so on. Antistatic fiber is a chemical fiber which is difficult to accumulate static charge. High-shrinkage fiber's boiling water shrinkage rate is higher than 15%. Flame-retardant fiber is only smoldering in flames. Spontaneous Combustion does not occur. Burning fiber will extinguish after leaving the flame.
