METHOD FOR RENDERING FINE DENIER MASS PIGMENTED POLYPROPYLENE FILAMENTS AND FIBER FLAME RETARDANT

摘要

Fine denier mass pigmented polypropylene filaments and fiber is rendered flame retardant by mixing flame retardant compounds such as a product which contains both aliphatic and aromatic bromine with an anti-oxidant and a U.V. stabilizer with polypropylene powder resin in order to make a flame retardant concentrate prior to mixing with polypropylene resin and pigments to make a color concentrate.
