Abstract: A method for preparing flame retardant mesh sheets and multi-filament fibers which do not do not generate halogen gas at the time of combustion. Also, a method for preparing mesh sheet and multi-filament fibers coated with a flame retardant including 1.5 to 15 wt % of red phosphorus and 10 to 70 parts by weight of an ammonium polyphosphate compound based on 100 parts by weight of the solid content of an aqueous solution of a polyolefin resin having a resin solid content of 20 to 45 wt%.

Abstract: A flame retardant for flameproof mesh sheets which does not generate halogen gas at the time of combustion and a flameproof mesh sheet comprising the same. Also disclosed is a flame retardant for mesh sheets comprising 1.5 to 15 wt % of red phosphorus and 10 to 70 parts by weight of an ammonium polyphosphate compound based on 100 parts by weight of the solid content of an aqueous solution of a polyolefin resin having a resin solid content of 2.0 to 45 wt % and a flameproof mesh sheet treated with this flame retardant.

Abstract: A flame retardant for flameproof mesh sheets which does not experience an increase in viscosity while it is kept and does not generate harmful halogen gas at the time of combustion and a flameproof mesh sheet comprising the same. The flame retardant for mesh sheets preferably comprises red phosphorus in an amount of 1.5 to 15 parts by weight and an ammonium polyphosphate compound in an amount of 10 to 70 parts by weight based on 100 parts by weight of an aqueous dispersion of an ethylene-vinyl acetate copolymer having a vinyl acetate content of 10 to 95 wt % and a resin solid content of 25 to 75 wt %.
