摘要:

采用过氧化氢/醋酸体系,对壳聚糖进行降解,得到了分子量为38.0万,20.0万,14.4万,9.2万,7.2万,3.2万,1.1万,0.4万的降解壳聚糖,将它们分别与丁烷四羧酸(BTCA)一起,对棉织物进行复合整理,测试了整理织物的折皱回复角,撕破强力,白度以及对金黄色葡萄球菌的抑菌率,讨论了壳聚糖分子量及浓度对整理织物抗皱/抗菌性能的影响。研究表明,通过一浴一步法,采用分子量为20.0万的壳聚糖,浓度为1.0 g?L-1,与BTCA一起对棉织物进行整理后,织物的折皱回复角为264.3 °,强力保留率为经向77.3 %,纬向63.5 %,白度为68.3,抑菌率为68.7 %;加入10.0 g?L-1的抗菌剂AGP,与BTCA一起对棉织物进行整理后织物的抑菌率可达到98.5 %,折皱回复角为263.0 °,强力保留率经向为83.5 %,纬向为76.4 %,白度为69.1。

Abstract:

H2O2 and CH3COOH were used to degrade chitosan(CTS), several CTS samples with different molecular mass were obtained, including 380000, 200000, 144000, 92 000, 72000, 32000, 11000, and 4000. These CTS samples were respectively used to treat cotton fabric together with butanetetracarboxylic acid (BTCA). Wrinkle recovery angle(WRA), Tearing strength rate(TSR), whiteness index(WI) and antibacterial rate of S.aureus of the composite finished fabrics were tested. Effect of CTS molecular mass and concentration on the anti-winkle and antibacterial properties were discussed. The results show that the WRA of cotton fabric is 264.0 °, warp TSR is 77.3 %, weft TSR is 63.5 %, WI is 68.3 and antibacterial rate of S.aureus is 68.7 %, which treated with CTS(molecular mass 200000, 1.0 g?L-1) and BTCA by one-bath process. When 10.0 g?L-1 antibacterial agent AGP was used together with CTS and BTCA, the antibacterial rate of finished cotton fabric is 98.5 %, WRA is 263.0 °, warp TSR is 83.5 %, weft TSR is 76.4 %,and WI is 69.1.
