Abstract:
1. A process for the fire retardation of textile materials, comprising applying an aqueous suspension of pentabromobenzyl acrylate (“PBBMA”) to the textile materials and polymerizing the PBBMA by heating at temperatures above 130° C., wherein the aqueous suspension of PBBMA comprises PBBMA in the form of finely ground particles having a size smaller than 50 μm that are obtained by wet grinding and further comprises at least one suspending agent selected from the group consisting of xanthan gums, anionic purified suspending agents, nonionic purified suspending agents, sodium modified montmorillonit, naphthalene sulfonic acid-formaldehyde condensate sodium salt, sodium salts of sulfonated lignin calcium salts of sulfonated lignin, ammonium salts of sulfonated lignin, and acrylic acids/acrylic acids ester copolymer neutralized—sodium polycarboxyl, and a wetting agent selected from the group consisting of alkyl naphthalene sufonates or their sodium salts, alkyl ether, alkylaryl ether, fatty acid diester and sorbitan monoesters, and polyoxyethylene (“POE”) compounds.
