Abstract

PURPOSE: To color a fiber or molded article (F) in a deep lustrous color without degrading the fiber strength and using a dye or pigment, by heating F consisting of a polyvinyl alcohol at a specific temperature in the absence of oxygen.
CONSTITUTION: A fiber or a molded article comprising a vinyl alcohol polymer consisting of 90mol% or more, preferably 95mol% or more, vinyl alcohol units is preheated at preferably 120W160°C for several min, and heated and colored at 100°CW(10°C lower than the melting point of the polymer) in a state of substantial absence of molecular oxygen, e.g. in vacus or an inert gas such as nitrogen.
EFFECT: Improved resistance to washing.
USE: A material for a wig or hair of a doll.
