FLAME-RETARDING AGENT AND FLAME-RETARDING METHOD FOR POLYESTER-BASED FIBER

摘要

PROBLEM TO BE SOLVED: To provide a flame-retarding agent capable of imparting a polyester textile product with persistent flame retardancy, to provide a flame-retarding method using the agent, and also to provide a flame-retarded polyester textile product obtained using the above agent.;SOLUTION: The flame-retarding agent is produced by mixing together (A) a first flame-retarding agent prepared by dispersing in water a certain kind of an aromatic diphosphate (e.g. tetra(2,6-dimethylphenyl)-m-phenylene phosphate) so as to be in the form of microparticles ≤0.7 μm in average size in the presence of a specially selected certain kind of a nonionic surfactant and a certain kind of an anionic surfactant and (B) a second flame-retarding agent prepared by emulsifying in water biphenylyl diphenyl phosphate in the presence of the nonionic surfactant and the anionic surfactant.;COPYRIGHT: (C)2009,JPO&INPIT
