摘要： A flameproof rayon fiber having excellent flameproofness as well as excellent flame retardance, a method for manufacturing the same, and a flameproof fiber structure are provided. The flameproof rayon fiber according to the present invention includes components of silicon and sodium. Glass remains when the fiber is burned at 800° C., the glass component has a property of softening at 800° C., and when subjected to an X-ray fluorescence analysis, the rayon fiber has a silicon content in the range of 5 to 30% by mass and a sodium content in the range of 0.1 to 3% by mass. The flameproof rayon fiber according to the present invention can be manufactured by preparing an undiluted viscose solution; adding a solution containing a silicate compound containing an alkali metal to the undiluted viscose solution so as to make an alkali metal-containing silicate compound-added viscose solution; performing spurning by extruding the alkali metal-containing silicate compound-added viscose solution through a spinneret into a spinbath containing sulfuric acid, thus producing a fiber to be treated containing the silicate compound; and treating, in a scouring or aftertreatment process, the fiber to be treated with a solution having a pH in the range of 4 to 11 and a buffer action and containing sodium. A flameproof fiber structure of the present invention contains at least 30% by mass of the flameproof rayon fiber.

摘要： A rayon fiber that does not use a halide-based flame retardant, a phosphorous flame retardant or an organic solvent, has excellent flameproofness and launderability and is biodegradable when buried in the soil at the time of disposal, and a method for manufacturing the same are provided. The flameproof rayon fiber according to the present invention contains components of silicon and magnesium, and a compound containing the components of silicon and magnesium is amorphous. This rayon fiber can be manufactured by preparing a viscose solution, adding a solution containing a silicate compound containing an alkali metal to the viscose solution so as to make a silicic compound-added viscose spinning solution containing the alkali metal, performing spinning by extruding the silicate compound-added viscose spinning solution containing the alkali metal through a spinneret into a spinbath containing a sulfuric acid, thus producing a fiber to be treated containing the silicate compound, and treating the fiber to be treated using a magnesium-containing solution in a scouring process or an aftertreatment process.
