Abstract
柿漆作为天然染料,其染色织物具有防水防腐的优点.以赋予棉织物抗菌性和紫外防护性能为目的,采用柿漆对棉织物进行直接染色处理.利用扫描电子显微镜观察棉织物的表观形态,PhabrOmeter织物手感评价测试仪测定织物风格,得到染色棉织物存在硬化问题;探究染色次数和染液浓度对棉织物K/S值、增重率和缩率的影响.通过正交试验设计优化染色工艺,测定染色棉织物的抗菌性能、接触角、紫外线防护性能、色牢度以及风格评价,分析柿漆染色对棉织物性能的影响.结果表明:适宜的染色时间为15 min,柿漆稀释浓度为1:4,染色次数为8次,染色棉织物色牢度良好,且具有较佳的疏水性能、抗菌性能和抗紫外性能,硬挺度增加.
