    Abstract: PROBLEM TO BE SOLVED: To obtain a molded article consisting of or containing a vinyl alcohol polymer and free from stickiness even in wet hot state by reacting the article with a specific polyisocyanate compound to form a crosslinking structure. SOLUTION: A cloth made of a fiber consisting of or containing a vinyl alcohol polymer is made to react with a polyisocyanate compound containing two or more isocyanate groups in the molecule wherein at least one of the isocyanate groups is a blocked isocyanate blocked with a heat-dissociating blocking agent composed of at least one kind of compound selected from ethylenimine, methyl ethyl ketoxime and ε-caprolactam. A crosslinking bond is formed by this process to suppress the cloth to grow sticky in wet hot state.
