摘要
为开发生态多功能棉织物,采用柠檬酸、马来酸、大豆蛋白对棉织物进行改性处理,通过复合羧酸的桥联作用,使大豆蛋白与棉织物形成化学键交联结合,研究处理条件对棉织物增重率的影响,并得出最优工艺参数。红外光谱和光电子能谱测试表明,复合羧酸与棉纤维大分子按环酐机制产生酯化交联,大豆蛋白借助复合羧酸的桥联作用以酰胺键共价结合在棉织物上。大豆蛋白改性棉织物的断裂强力略有下降,再经仙人掌提取物处理的大豆蛋白改性棉织物抗紫外线性能明显提高,药物缓释试验显示,大豆蛋白改性棉织物作为药物载体对仙人掌提取物的缓释效果良好。
To develop an eco-friendly and multifunctional cotton fabric, the modification treatment of cotton fabric was undertaken using citric acid, maleic acid and soybean protein so that the chemical bonding between soybean protein and cotton fabric was formed through the bridging function of muhicarboxylic acids. Effects of treating conditions on the weighting percentage of cotton fabric were analyzed and the optimized process parameters were obtained. The characterization of infrared spectra and X-ray photoelectron spectrometry showed that the esterification crosslinking occurred between muhicarboxylic acids and macromolecules of cotton fiber according to ring-anhydride mechanism, while the soybean protein was adhered to the cotton fabric with amido bond by the bridging function of multicarboxylic acids. The breaking strength of soybean protein modified cotton fabric slightly decreased, whereas the anti-ultraviolet-ray property of the modified cotton fabric after cactus extract treatment improved remarkably. Furthermore, the drug controlled release test showed that when soybean protein modified cotton fabric was used as the carrier for cactus extract, good controlled release effect was achieved.
