SERAT-SERAT POLIESTER DENGAN KECENDERUNGAN BERKURANG PADA PILLING DENGAN METODA PRODUKSINYA

摘要

A new polyester fiber comprises: (i) fiber forming polymer containing at least 90 mol.% polyethylene terephthalate; (ii) a diol from (di)ethylene and triethylene glycol; (iii) 0.003 - 1.0 wt.% finely dispersed silicon dioxide or silicic acid particles; (iv) 0.003 - 2.0 wt.% silicon oil; and (v) optionally conventional additives. The diol is in an amount to give the polyester fiber a relative viscosity of 1.37 - 1.58 in 1 % cresol. An Independent claim is also included for the preparation of the fiber by mixing, melting and spinning the components.
