摘　　要：采用丁烷四羧酸(BTCA)为整理剂,次亚磷酸钠(SHP)与不含磷催化剂HD-SP为复合催化剂对棉织物进行整理,研究了该体系对织物表面pH值及抗皱性能的影响,并用傅里叶红外光谱(FT-IR)、离子相对浓度计算,研究了复合催化剂的作用机制。实验结果表明:复合催化剂整理后的织物表面pH值可达到国标的要求,可省去焙烘后的水洗工序;与使用质量浓度16 g/L SHP相比,以10 g/L SHP、20 g/L HD-SP复合时,整理织物的抗皱性能相差不大,但SHP的用量减少了37.5%。根据FT-IR结果,复合催化剂与纯SHP相比,BTCA与纤维素纤维酯化交联程度相当;根据离子相对浓度计算,更多羧基被复合催化剂转化成了羧酸盐,织物表面pH值得以提高。Cotton fabric was treated by using butane tetracarboxylic acid （BTCA） as finishing agent, and sodium hypophosphite （SHP） and non-phosphorus HD-SP as composite catalyst. The influence of the composite catalyst on the pH value and the anti-wrinkle property of treated fabric were investigated. The function mechanism of the composite catalyst was also studied by Fourier transform infrared spectroscopy （FT-IR） and ion relative concentration calculation. The results indicated that the pH value of fabric which was treated by the composite catalyst can meet the requirement of national standard, and consequently the washing process can be omitted. Besides, the anti-wrinkle property of fabric treated by SHP 10 g/L and HD-SP 20 g/L as the composite catalyst was comparable with that of fabric treated with SHP 16 g/L. However, the dosage of SHP can be decreased by 37.5%. FT-IR analysis showed that the amount of ester bonds on fabric treated by the composite catalyst was the same as that of fabric treated by SHP alone. Besides, more carboxyl groups were converted to carboxylate by the the composite catalyst according to ion relative concentration calculation, so that the pH value of treated fabric was increased.
