HALOGEN-CONTAINING FLAMEPROOF FIBERS, METHOD FOR PRODUCING SAME, AND FLAMEPROOF FIBER PRODUCT USING SAME

摘要

The present invention provides a halogen-containing flame-retardant fiber, a method for producing the same, and a flame-retardant fiber product using the same, in which a halogen-containing fiber can be highly flame-retarded without addition of antimony compounds that may adversely affect the environment and human bodies. The halogen-containing flame-retardant fiber of the present invention includes: 100 parts by mass of a halogen-containing polymer containing 17 to 70 parts by mass of a halogen; and 1.3 to 20 parts by mass of a molybdenum compound. The average particle diameter of the molybdenum compound as expressed in median diameter is 10 nm or more and less than 600 nm. The flame-retardant fiber product of the present invention includes the above halogen-containing flame-retardant fiber. The production method of the present invention includes spinning a composition that contains 100 parts by mass of a halogen-containing polymer containing 17 to 70 parts by mass of a halogen, and 1.3 to 20 parts by mass of a molybdenum compound. In the composition for the spinning, an average particle diameter of the molybdenum compound as expressed in median diameter is 10 nm or more and less than 600 nm.
