In fact, the difference between polyester staple fiber and polyester filament can be seen on the naked eye. Generally, the fabric woven from filament is shiny and smooth, similar to nylon fabric. It is easy to remember this. The distinction. But in fact, there is still a big difference between polyester staple fiberand polyester filament. Below, Qinfeng will answer for you.

polyester staple fiber: The so-called polyester staple fiber is a short fiber of a few centimeters to a dozen centimeters, a cotton staple fiber and a wool type. Cotton type is mostly used for spinning, such as wool, weaving, etc.; staple fiber is used to blend with other fibers such as cotton.

Polyester filament: The so-called polyester filament is a filament with a length of more than a kilometer, and the filament is wound into a mass. Generally, it can be divided into three categories: POY (pre-oriented yarn) FDY (full drawn yarn) DTY (low-elastic yarn).

1. POY is mainly used in post-processing production such as production of DTY, DT, ATY, and can also be directly applied to the silk textile industry;

2.FDY is mainly used in the clothing and textile industries;

3.DTY is an ideal raw material for knitting (weft knitting, warp knitting) or woven processing. It is suitable for making apparel fabrics (such as suits and shirts), bedding (such as quilts, bedspreads, mosquito nets) and decorative items (such as curtain fabrics, Sand release, wall covering, car interior fabric, etc.

Characteristics and uses of polyester staple fiber:

Strength: polyester staple fiber is nearly 1 times stronger than cotton and 3 times higher than wool, so polyester fabric is durable.

Heat resistance: It can be used at 70 to 1700C, which is good in heat resistance and thermal stability of synthetic fibers.

Elasticity: The elasticity of polyester is close to wool, the wrinkle resistance is higher than other fibers, the fabric is not wrinkled, and the maintenance is good.

Wear resistance: Polyester's wear resistance is second only to nylon, ranking second in synthetic fiber.

Water absorption: Polyester has low moisture absorption rate and good insulation performance, but due to low water absorption, static electricity generated by friction is large and dyeing performance is poor.

As a fiber for clothing, polyester has a wrinkle-free and non-ironing effect after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., and is widely used in various clothing materials and decorative materials.

Polyester is industrially used for conveyor belts, tents, canvas, cables, fishing nets, etc., especially for polyester cords for tires, which are close to nylon in performance. Polyester can also be used for electrical insulation materials, acid-resistant filter cloths, and pharmaceutical industry fabrics.
