[PROBLEMS] Recently, there has been a tendency to demand a light, thin, warm, and high-quality textile product that is easy to move, and animal protein fiber materials are required to have further improved comfort and warmth. However, there are few research results in this area. [MEANS FOR SOLVING PROBLEMS] As a result of research on the practical application of a modified processing method for animal protein fiber materials that are gentle to the skin, the present inventors have given a water-soluble zirconium compound under mild processing conditions or a crosslinking agent. It has been found that wet exothermic properties can be effectively imparted to animal protein fiber materials with excellent economic efficiency. |
