1. Different concepts
1. Polyester filament: It is made of polyester, and it is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG). It is esterified or transesterified. Fibre-forming polymer made from polycondensation reaction-polyethylene terephthalate (PET), fiber after spinning and post-treatment.
2. Staple fiber: It is a fiber obtained by cutting polyester fiber into a tow.
Second, the characteristics are different
1. Polyester filament: high strength; good heat resistance, can be used at -70 ℃ ~ 170 ℃; good elasticity, polyester elasticity is close to wool; good wear resistance, polyester wear resistance is second only to nylon; water absorption it is good.
2. Staple fiber: abrasion resistance, polyester wear resistance is second only to nylon and ranks second in synthetic fiber; water absorption, polyester has low water absorption and moisture regain, good insulation performance, but due to low water absorption, friction Large static electricity and poor dyeing performance.
3. Different uses
1. Polyester filament: It can be used as clothing fiber and is widely used in various clothing materials and decorative materials. Polyester can be used industrially for conveyor belts, tents, canvas, cables, fishing nets, etc.
2. Staple fiber: mainly used in the cotton spinning industry, spinning alone or blended with cotton, viscose fiber, hemp, wool, vinylon, etc. The resulting yarn is mainly used for clothing weaving, but also for home improvement fabrics and packaging fabrics , Filling and warming materials.
