摘要： A non-inflammable fiber material and a process for producing the same are disclosed, said process comprising the steps of:obtaining thready materials, knitted goods, or woven goods, which are composed of a mixed yarn consisting of polymetaphenylene isophthalamide fibers of thermal decomposition temperature not smaller than 350.degree. C. and rayon fibers, or which are composed of 100 weight parts of a mixed yarn consisting of polymetaphenylene isophthalamide fibers of thermal decomposition temperature not smaller than 350.degree. C. and rayon fibers, and from 20 to 100 weight parts of a polymetaphenylene isophthalamide fiber yarn of thermal decomposition temperature not smaller than 350.degree. C., at least said rayon fibers in said thready materials, knitted goods, or woven goods being treated with one or more chemical agents selected from a first chemical agent group consisting of ammonium sulfamate, diammonium imidodisulfonate, ammonium sulfate, ammonium bisulfate, ammonium thiosulfate, ammonium sulfite, and ammonium bisulfite, and one or more chemical agents selected from a second chemical agent group consisting of ammonium dihydrogen phosphate, diammonium hydrogen phosphate, and guanidine phosphate; andheat treating said thready materials, said knitted goods, or said woven goods at from 200 to 260.degree. C. so as to denaturate said rayon fibers in said thready material, said knitted goods, or said woven goods into thermally decomposed heat treated carbonized fibers.
