A flame retardant union fabric obtained by combining (A) 30 to 70% by weight of a fiber comprising as a main component a flame retardant halogen-containing fiber made of a composition comprising 100 parts by weight of an acrylic copolymer of 30 to 70% by weight of acrylonitrile, 30 to 70% by weight of a halogen-containing vinyl monomer and 0 to 10% by weight of a vinyl monomer copolymerizable with them, 10 to 30 parts by weight of an antimony compound and 8 to 30 parts by weight of a zinc stannate compound, with (B) 70 to 30% by weight of a cellulosic fiber. The flame retardant union fabric shows a high flame resistance which passes the M1 class of NF P 92-503 burning test in France even after the post-treatment.

Flame-retardant union fabric

A filament for brushmaking which is excellent in yield and in bend recovery, and when used in making paintbrushes, can give brushes with good paintability. A filament has a specified cross section having a plurality of cavity of hollow structures, the hollow ratio being 20 to 60% based on the whole cross-sectional area, capable of affording greater yield, ready processability at its end, excellent stiffness and excellent cleanability.
