Crosslinking analysis of polycarboxylic acid durable press finishing of cotton fabrics and strength retention improvement

摘要: Cotton fabric is treated in different concentrations of BTCA and SHP solutions. The weight gain confirmed by FTIR analysis, the peak ratio 1720 cm-1/1380 cm-1 has a good linear relation with gain. results show that most effective for durable press finishing at around 2%. moisture regain decreases as increases before 10%, then high levels These indicate except inter- intramolecular crosslinking, some side grafts are formed during treatment, concentrations, quantity increases. When cured tension, crosslinks can be reduced fabric's strength retention improve from 45% to above 75%.
