<p>PURPOSE:To provide a flameproofing agent capable of giving polyester textile products flameproofness of high durability when imparted them therewith, consisting of a dispersion prepared by finely dispersing a bromocycloalkane compound using a specific self-emulsifiable compound. CONSTITUTION:This flameproofing agent consists of a dispersion which can be prepared by finely dispersing (A) a mixture of 65-95wt.% of a bromocycloalkane, esp. hexabromocyclododecane, >=190 deg.C in melting point and 35-5wt.% of such compound <=160 deg.C in melting point using (B) a self-emulsifiable polyester compound of formula I, II or III [X is of formula IV; Y is of formula V; Z is a mixture of X and Y at the molar ratio X/Y of (50:50) to (90:10); R is 2-4C alkylene; x is 1-150; y is 1-5], e.g. a polycondensate of bishydroxyalkyl terephthalate and polyethylene glycol. Polyester textile fabric is subjected to the same bath treatment with a dyeing bath by e.g. a jet dyeing machine using the above dispersion to impart it with durable flameproofness. The resultant polyester textile fabric is suitable for cation-dyeable polyester fiber-combined textile products. This flameproofing method can effectively prevent dyeing machine vessel contamination.</p> |
