柠檬酸和壳聚糖对棉织物抗菌整理的研究
棉织物 壳聚糖 柠檬酸
2009/10/14
针对柠檬酸和壳聚糖在棉织物抗菌整理中的应用,研究了壳聚糖的浓度对棉织物抗菌性的影响,多元羧酸的含量对壳聚糖固着率的影响及焙烘温度对壳聚糖固着率和白度的影响;并对整理后棉织物的性能进行了测试分析。结果表明,用柠檬酸和壳聚糖的混合液对棉织物进行抗菌整理的效果是明显的,整理后棉织物的耐久定型和折皱回复率都有提高,而且经反复洗涤后,其抗菌性仍达到80%以上。

棉织物 乙二醛 水解淀粉
2009/10/14
采用水解淀粉与乙二醛复配整理剂对棉织物进行抗皱整理,通过正交试验,讨论水解淀粉、乙二醛和催化剂用量、焙烘温度和焙烘时间等因素对整理后棉织物折皱回复角提高率和断裂强力保持率的影响。得出最优整理工艺参数:淀粉质量浓度40 g/L、乙二醛质量浓度7 g/L、催化剂质量浓度40 g/L、焙烘温度140℃、焙烘时间5 min。在此最优工艺条件下,整理后棉织物的折皱回复角提高率为30%~45%,断裂强力保持率...
生物酶处理对亚麻/棉织物杂质的去除作用
亚麻/棉织物 生物酶
2009/10/14
研究了果胶酶、纤维素酶、木聚糖酶和漆酶单一及混合处理对亚麻/棉织物上果胶和木质素的去除作用及前处理效果,并与传统工艺进行了比较。结果表明,虽然生物酶前处理对织物的强力损失远低于传统的前处理工艺,但对木质素的去除率与传统前处理工艺相比还有很大差距,而且,对果胶的去除率也没有传统前处理工艺好。在前处理效果上,生物酶前处理的润湿性和麻皮去除情况与传统前处理工艺相比有一定差距。
