改性苎麻纤维与羊毛同浴染色研究 总被引:3,自引:0,他引:3
选用氢氧化钠和SA12分别作为苎麻的碱处理剂和阳离子改性接枝剂,对精干麻碱处理后进行阳离子改性处理,并用酸性染料染色.探讨了染色温度、酸洗工艺对改性苎麻纤维染色性能的影响,确定了毛麻同浴染色工作曲线.试验结果表明,酸洗可以减缓碱改性苎麻阳离子接枝改性的速度,使在苎麻上接枝的阳离子基团分布均匀;分时段升温的方法使染色性能略有差异的改性苎麻和羊毛的得色率趋向一致,实现毛麻的酸性染料同浴染色. 相似文献

等离子体引发亚麻织物接枝改善染色性能 总被引:4,自引:0,他引:4
亚麻纤维染色性能存在缺陷,以往多采用阳离子化学改性法、化学接枝法、稀土法、涂料法、添加增深助剂等化学方法来改善其染色性能。文章研究了大气压介质阻挡放电引发亚麻织物接枝丙烯酸的可行性,进行了亚麻织物的接枝与染色实验。结果表明,大气压介质阻挡放电可以引发亚麻接枝丙烯酸,并且很好地改善了染色性能。 相似文献

In this study, a modification procedure for ramie fabrics was developed using modified cellulases. Cellulase was modified by covalent coupling to Eudragit S-100, which resulted in a larger molecule, to trigger its activity toward the cellulosic fiber surface. The modified fabrics were characterized by using atomic force microscope, thermogravimetric analysis, and Kawabata Evaluation System for Fabric techniques in order to determine their morphology, thermal stability, and handle. In addition, the moisture evaporation, wicking property, and air permeability of the modified ramie fabrics were investigated. Furthermore, the weight loss and copper number were determined to identify the damages in the modified ramie fibers. The results show that the modified cellulase can prevent excessive damage to ramie fabrics with the desired performance because the hydrolytic attack of the modified cellulase is restricted to the surface of the ramie fibers. 相似文献

The extra-long length of ramie fibers and the high variation in fiber length has a negative impact on the spinning processes. In order to better study the feature of ramie fiber length, in this research, the probability density function of the mixture model applied in the characterization of cotton fiber length was used to fit the ramie fiber length distribution tested by the Y131 wool fiber comb stapling sorter. Furthermore, the generation of ramie fiber length distribution with the commonly used ramie fiber length parameters was also studied, and it was concluded that ramie fiber length distribution could be generated by the corresponding tested fiber length parameters. 相似文献
