Abstract

Sodium phosphate salts catalyzed the reaction of THPC with urea. Cotton textiles treated with a solution containing 26.6% THPC, 8.4% urea, 4% dibasic sodium phosphate and sufficient NaOH to adjust the pH to 6, dried 85°C and cured at 160°C for 1 to 2 minutes passed the DOC FF 3-71 flame test after 50 laundry cycles. The samples retained 90 and 65-70% of their breaking and tearing strength respectively without the use of softeners
