Abstract
Cotton/polyester carpet materials are resistant to surface flame spread after esterification of the cellulosic fibers with polycarboxylic acid and suitable catalyst. The crosslinked cellulose-containing materials passed the re quired flammability standards for carpet when subjected to the methenamine pill test. This test is much less severe than the rigorous vertical flame test method required for textiles designated for other end uses. Cotton-containing carpet materials finished with 5-10% polycarboxylic acid, such as 1,2,3,4-butanetetracarboxylic acid (BTCA) or citric acid, and sodium phosphate, sodium hypophosphite, sodium bicarbonate or sodium carbonate catalyst were found to meet test method specifications when proper processing and fixation conditions were employed. Specific details of processing conditions and results of flammability tests are presented.
