すぐれた特性を有している。 The polyacetal fiber used in this invention is a fiber produced by super-stretching polyacetal resin. Polyacetal resin is a polymer having an acetal group in its main chain and is a type of polyether, and is usually a formaldehyde polymer or copolymer. The homopolymer is called polyoxymethylene. It is a crystalline polymer with little branching and is used as an engineering plastic. Delrin (du Pont) is used as a homopolymer, and Duracon (Duracon) is used as a copolymer.
Celcon, Cellanese), etc. Then, in order to ultra-stretch this polyacetal resin and make it into fibers, it is ultra-stretched in a highly crystalline state to 20 times or more the normal amount. Polyacetal fiber has the following excellent properties.
