蚕丝蛋白对涤纶织物的亲水整理研究

Research on Hydrophilic-Finishing of Polyester Fabric with Silk Protein

将碱减量预处理过的涤纶织物放入氯化亚砜密闭气体中,以DMF为催化剂,进行酰氯化反应,得到预处理涤纶织物,然后将预处理织物放入丝胶或丝素水溶液中进行接枝反应,使得丝胶或丝素被整理到涤纶织物的表面。对整理前后织物进行红外光谱、热失重、吸放湿性、断裂强力测试分析,结果表明:采用对织物进行蚕丝蛋白整理可以有效地将丝胶和丝素整理到织物的表面上,丝胶或丝素整理后织物的亲水性和吸湿性有了明显提高,断裂强力较预处理织物没有太大变化,但是热性能有所降低。

Firstly, polyester fabric was pre-treated by alkali deweighting. Then, the fabric was put into the sulfoxide chloride atmosphere for acylating chlorination reaction with DMF as catalyst. Then, the pre-treated fabric was gained and put into an aqueous solution of sericin or silk fibroin for graft reaction. In this way, sericin or fibroin was finished on the surface of polyester fabric. Pre-finished or post-finished fabrics were tested by infrared spectroscopy, thermo- gravimetry, hygroscopicity and breaking strength tester. The results indicate that： the fabric treated by silk protein can effectively graft sericin or fibroin on the fabric surface; hydrophily and hygroscopicity of the fabric finished with sericin or fibroin are obviously improved; breaking strength barely varies, but thermal property decreases to some extent.
