FLAME-RETARDANT SYNTHETIC FIBER, FLAME-RETARDANT FIBER COMPLEX BODY AND NONWOVEN FABRIC AS FLAME-BLOCKING BARRIER

摘要

PROBLEM TO BE SOLVED: To provide a flame-retardant synthetic fiber that can suitably be used for textile product needing a high level of fire retardancy by expressing extremely high degree of carbonization on burning, flexibility, and shape retention and further provide the flame retardant complex body and mattress obtained by using the complex body.;SOLUTION: The flame-retardant synthetic fiber comprises a zinc oxide component including 20 to 80 wt.% of zinc oxid, and 3 to 55 pts.wt. of condensed phosphoric acid compound and 0 to 30 pts.wt. of antimony compound so that the total of the complex body and the antimony compound may be 3 to 55 pts.wt. based on 100 pts.wt. of chlorine-including polymer including 30 to 70 wt.% of acrylonitrile unit, 70 to 30 wt.% of a chlorine-containing vinyl and/or chlorine-including vinylidene monomer unit, and 0 to 10wt.% of vinyl monomer unit that is copolymerizable with the monomers stated above. The flame retardant fiber complex body comprises more than 10 wt.% of (A) the retardant synthetic fiber, and (B) less than 90 wt.% of natural fiber and/or chemical fiber and the mattress is obtained by using the flame-retardant fiber complex body.;COPYRIGHT: (C)2008,JPO&INPIT
