What is polyester fiber? Polyester fiber (Polyesterfibre) from organic two-yuan acid and two-yuan alcohol polycondensation, become polyester fiber spinning income polyester fibers. The industrial mass production of poly (ethylene terephthalate) Two ester fiber is made of polyethylene terephthalate, China's commodity called polyester. Polyester fiber is the first large variety of synthetic fibers. Therefore, polyester fiber is actually the "polyester" that we Americans often say.
Compound, polyethylene terephthalate two ester fiber
The ratio of polyester is 1.38, melting point is 255〜260℃, 205 ℃ start bonding, safe ironing temperature is 135 ℃, low humidity, only 0.4% of the filament rupture strength is 4.5 ~ 5.5 grams/denier, short fiber is 3.5 ~ 5.5 grams/denier; the elongation of the filament is 15〜25%, the short fiber is 25〜40%, the strength of the high-strength fiber can reach the 7〜8 gram/denier, the breaking elongation rate is 7.5 ~ 12.5%.
