Features And Uses Of Polyester Silk Yarn

　　Polyester silk yarn is a polyester filament. Polyester silk yarn is a fabric woven from ultra-hollow structural yarn (hollow rate 35%~40%). Containing a large amount of stagnant air, it is light and warm, and at the same time has moderate ventilation performance without a stuffy feeling. The cost of polyester silk yarn is low, and it is used for clothing lining, ties, embroidery thread, thermal underwear, etc. It feels rough, not as smooth as silk, but has a good gloss, and is mostly used for men's ties.

　　Features of polyester silk yarn

　　Strength: The strength of polyester yarn fiber is nearly 1 time higher than that of cotton and 3 times higher than that of wool, so the polyester fabric is strong and durable.

　　Heat resistance: It can be used at -70°C to 170°C, and it has the best heat resistance and thermal stability among synthetic fibers.

　　Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance exceeds that of other fibers. The fabric does not wrinkle and has good shape retention.

　　Abrasion resistance: The abrasion resistance of polyester is second only to nylon, ranking second among synthetic fibers.

　　Water absorption: Polyester has low moisture regain and good insulation performance. However, due to low water absorption, high static electricity generated by friction, and poor natural adsorption of dyes, polyester is generally dyed by high-temperature and high-pressure dyeing.

　　Dyeability: Polyester itself lacks hydrophilic groups or dye acceptor parts, so the dyeability of polyester is poor. It can be dyed with dispersed dyes or non-ionic dyes, but the dyeing conditions are relatively harsh.

　　Uses of polyester silk yarn

　　Polyester is used as a clothing fiber, and its fabric can achieve wrinkle-free and non-ironing effects 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 and decorative materials. Polyester can be used in conveyor belts, tents, canvases, cables, fishing nets, etc. in industry, especially polyester cords for tires, which are close to nylon in performance.

　　Polyester can also be used in electrical insulation materials, acid-resistant filter cloths, pharmaceutical industrial cloths, etc. Synthetic fibers have been widely used in various fields of the national economy because of their high strength, wear resistance, acid resistance, alkali resistance, high-temperature resistance, light weight, warmth retention, good electrical insulation, and resistance to mold and moth.
