丝胶蛋白对涤纶织物的亲水整理

Hydrophilic finishing of polyester fabrics with sericin

用自制功能性单体玛巴斯A,在无氧条件下利用引发剂玛巴斯B引发自由基聚合,通过浸轧丝胶整理液,在一定温度下饱和汽蒸的方法对涤纶织物进行整理,在对涤纶织物进行接枝的同时将丝胶包覆,使丝胶整理到涤纶织物表面。采用傅里叶变换红外光谱(FTIR)、扫描电镜(SEM)和荧光分析等对整理前后织物表征分析,结果表明丝胶已在涤纶织物表面固着。对整理前后织物进行吸放湿性等相关性能的测试,表明涤纶织物经丝胶整理后回潮率、毛效和吸湿性能都得到了一定程度的改善,从而改善了涤纶织物的服用性能。

This paper uses initiator Marbas B to initiate free radical polymerization under anaerobic conditions using home-made functional monosome Marbas A, finishes polyester fabrics at a certain temperature with the method of saturated steaming by padding sericin finishing liquor, and coats sericin while grafting polyester fabrics so as to make sericin on the surface of polyester fabrics. This paper conducts an analysis on characterization of fabrics before and after finishing using Fourier transformation infrared spectroscopy （FTIR）, scanning electron microscope and fluorescence analysis. The result shows that sericin has been fixed on the surface of polyester fabrics. This paper conducts a test on relevant properties of fabrics before and after finishing such as hygroscopicity and moisture releasability, showing that the moisture regain, capillary effect and hygroscopicity of polyester fabrics subject to finishing with sericin have been improved to a certain extent, thus improving the wearability of polyester fabrics.
