PROCESS FOR FLAMEPROOFING ORGANIC FIBER MATERIAL BY THE TRANSFER PROCESS

摘要

A process for flameproofing organic fiber material by the dry thermal transfer process is provided. In this process, a preparation is applied to an inert carrier which is then brought into contact with fiber materials, such as polyamide, polyacrylonitrile or linear polyester fibers; thereafter the carrier and the material are subjected to a heat treatment at not less than 80 DEG C and the finished material is then separated from the carrier. The preparation used in this process contains a halogen compound of the formula WHEREIN A is halogen, hydroxyl, alkoxycarbonyl, halogenoalkoxy or halogenophenyl and X1, X2, X3, X4 and X5 are each halogen, alkyl, hydroxl or hydrogen, but at most one of the radicals X1, X2, X3, X4 and X5 is alkyl or hydroxyl and at least one of the radicals is halogen, and X1 and A can together be a radical of the formula -CO-O-CO.
