2071525 9207125 PCTABS00012 A flame-retardant fiber excellent in the resistance to thermal coloration and a process for producing the same, which fiber is mainly composed of 80 to 20 parts by weight of a halogenated polymer and 20 to 80 parts by weight of polyvinyl alcohol and contains 5 to 35 parts by weight of an antimony compound such as antimony pentaoxide, 0.13 to 5.0 parts by weight of an octyltin heat stabilizer composed of 50 to 30 % of mercaptide and 50 to 70 % of laurate, and further preferably 0.3 to 10 parts by weight of stannic acid, each based on 100 parts by weight of the main components. This fiber can make various flammable fibers, when composited therewith, flame-retardant effectively and provide textile products excellent in flame retardation and the capability of passing through the post-treatment step in professional laundries.
