PROCESSO PARA A FABRICACAO DE FIBRAS DE POLIESTER APERFEICOADAS

摘要

The dispersibility in water of synthetic fiber, especially polyester fiber, is improved by coating with an improved copolyester coating, the improvements being that the copolyester is modified so as to contain polar groups that provide sites that are susceptible to a cross-linking-type reaction, and that the resulting materials are then subjected to such cross-linking-type reaction, whereby the durability of the coating on the fiber is improved, and wherein advantages are obtained in the products obtained from such fibers.
