摘要
A hydrophilic polyester fiber is supplied with an aqueous mixed dispersion on the surface and made hydrophilic by being heated at 35° C. or higher, and the aqueous mixed dispersion employed contains a polyester-polyether block copolymer composed of a polyester component and a polyether component and is stable at lower than 35° C. and precipitates the polyester-polyether block copolymer when its dispersion state is broken by being heated to 35° C. or higher.
