Preparation and characterization of gelatin/cerium(Ⅲ) film

A novel gelatin film with antibacterial activity was prepared by electrostatic crosslinking using cerium (Ⅲ) nitrate hexahydrate as the crosslinking agent. The structure and properties of the films were investigated by Fourier transform infrared spectra, tensile tests, thermogravimetric analysis, static drop contact angle and disc diffusion method. The results showed that cross-linking could not only improve the thermal and mechanical properties and lower the hydrophilic property of the films, but also make...     

羊毛/低熔点皮芯复合纤维混纺织物性能研究

选用皮层为低熔点聚合物的皮芯复合纤维ES纤维分别以不同的比例和羊毛混纺,采用有热处理和无热处理2种工艺分别对上述织物进行后整理,通过折痕回复角、FAST风格测试和洗涤收缩率测试,评价了织物的尺寸稳定性和服用性能,并同纯羊毛织物性能进行比较.结果表明,混有ES纤维的羊毛织物经过热处理之后,尺寸稳定性和防毡缩性能均得到了明显提高.     

低熔点皮芯复合纤维改性毛织物的防毡缩性能

为改善毛织物的防毡缩性能,选用皮层为低熔点聚合物的皮芯复合ES纤维分别以不同的比例和羊毛混纺,采用有热处理和无热处理2种工艺对上述织物进行后整理,并通过扫描电镜观察经过热处理的纤维、纱线和织物内部的黏结情况,测试了纤维的最大黏结强力、纱线的收缩率和织物的洗涤收缩率。结果表明:混有ES纤维的羊毛织物经过热处理,防毡缩性能得到了有效的提高,洗涤收缩率测试结果达到了国际羊毛局(IWS)性能测试标准TM31的要求。
