Fabrication method of fiber structure with high color fastness and excellent flexibility and fastness

摘要

TECHNICAL FIELD The present invention relates to a method for improving the color saturation of a polyester structure obtained by coating an organosilicon resin on the surface and roughening the surface, and imparting flexibility and high-level properties. Part of the components constituting the fiber is hydrolyzed Of a resin composition having a low refractive index of 1.45 or less and emulsified with a polyoxyethylene alkyl ether represented by the following formula represented by the following general formula on the surface of a polyester structure for forming a large number of concave portions on the surface To 15% by weight of the fiber structure, and immersing the resin composition in which 1% by weight of nonylphenol having 9 moles of ethylene oxide as a penetrating agent is added and picked up by mangling to 80 to 150% , Drying at 100C or lower for 3 minutes or more, and setting at 160C or lower.
