Method for dyeing cross-linked acrylate fibers and fiber products containing cross-linked acrylate fibers dyed by the dyeing method

摘要

PPROBLEM TO BE SOLVED: To provide a method for dyeing a cross-linked acrylate fiber in which dyeing with durability is conventionally considered as impossible with the practical durability using a reactive dye without deteriorating performances such as moisture absorbing and releasing properties or deodorizing properties. PSOLUTION: The method for dyeing the cross-linked acrylate fiber is characterized as follows. The cross-linked acrylate fiber subjected to a cross-linkage introduction treatment with a hydrazine compound and a hydrolysis treatment with an aqueous solution of an alkaline metal salt is treated with the reactive dye under acidic conditions. The cross-linked acrylate fiber, as necessary, is subsequently treated under alkaline conditions. PCOPYRIGHT: (C)2006,JPO&NCIPI
