Polyester fiber or fiber, which has strong resistance to bowling formation, and the manufacturing process of such fiber or polyester fiber

摘要

For bowling of high resistance polyester fiber, it is recommended to apply anadil (1) to at least 90% polymer molecules (diethyl vinyl acid) of polyester component,After dissolution, 1-7% weightless (2) of the polyester component is uniformly separated as a single pass from equation I,In this case, the average weight of dupril core (oxypropylene) is 3000-4000, while that of polyethylene group (oxyethylene) is 20-60% by the weight of block copolymer, and the average molecular weight is 3750-10000, which is spun together in the usual way. Preferably, the acetate component is composed of ethyl dicarboxylate one (ethyl terephthalate) with a weight percentage of 2-4%.
