For more than a decade, the chemical fiber industry has developed rapidly, and polyester staple fiber manufacturers have gradually established the world's leading position in conventional fiber production. At the same time, high-performance fiber production is full of flowering, greatly shortened the level gap between nearly 30 years from developed countries. Chemical fibers are increasingly attractive in their unique charm. There are many types of polyester staple fiber fabrics, in addition to textile manufacturing pure polyester knitted items, there are many products that mix textiles or interleaved textiles with all kinds of textile fibers, and improve the pure polyester fabric, which is better than polyester short fibers. Taking features.

Polyester short fiber characteristics:

      1. High strength: The strength of polyester staple fibers is nearly 1 fold higher than the cotton, 3 times higher than the wool. Due to the low moisture absorption, its wet strength is substantially the same as the dry state strength. The impact resistance is 4 times higher than the nylon, 20 times higher than the adhesive fiber.

      2. Good elasticity: Flexible approach wool, when elongated by 5% to 6%, almost completely recovery. Polyester fabrics have high strength and elastic recovery ability, so the fabric is not wrinkled, the dimension is stable, and it is very durable.

      3. Good heat resistance: Polyester belongs to thermoplastic fibers, the melting point is relatively high, and can be used at 70 to 170 ° C, which is smaller than the heat capacity and thermal conductivity, and thus the heat resistance and insulation of the polyester short fibers are synthetic short fibers. OK.

      4. Good thermoplastic, poor melting: Since the surface of the polyester is smooth, the internal molecules are tight, so the polyester is good to heat resistance in the synthetic fiber fabric. At the same time, poor melting is poor, and the polyester fabric is like a sole, Mars and other easy to form a hole.

      5. Wear resistance: Polyester short fiber wear resistance ranks second in synthetic fibers, second only to a nylon of wear resistance Z.

      6. Corrosion resistance: bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids, and strong amazient, anti-ultraviolet capacity.

      7. Poor dyeness, but the color fastness is good, it is not easy to fade: the polyester molecular chain is less dyed by no specific dyeing group, and the polarity is small, the dye is poor, the dye molecule is not easy to enter the fiber .

      8. Poor hygroscopicity and gas permeability: Polyester fabric is wearing a hot sense, easy to strap static electricity, dust, affecting beauty and comfort, but easy to wash, not deformation.
