中文摘要：
茶色素易与蛋白质、脂类、糖类等生物大分子以各种形式进行有序结合，形成一种稳定体系。棉织物采用壳聚糖改性后，再采用茶色素染色，讨论了茶叶质量、染液pH值、染色温度和染色时间对织物K／S值的影响。优化的染色工艺为：茶叶25g，染液pH值6，染色温度100℃，染色时间60min。改性后的棉织物染后耐摩擦色牢度提高1～2级，耐水洗牢度提高0．5～1级，耐晒牢度提高1．5级，抗紫外线性能提高2—3倍，对大肠埃希菌和金黄葡萄球菌的抑菌率分别为75．15％和71．35％。
英文摘要：
Cotton fabric is modified by chitosan and then dyed with tea pigments. The influences of tea pigments dosage, pH value of dye liquor, dyeing temperature and time on K/S value of fabric are discussed. The dyeing process is optimized as： tea pigments 25 g, pH value 6, dyeing at 100 ℃ for d0 min. The cotton dyeings feature improved color fastnesses to rubbing, washing and light by 1-2, 0.5-1, and 1.5 levels respectively, and increased anti-ultraviolet performance. The antibacterial activity on Escherichia coil and Staphylococcus aureus are 75.15% and 71.35% respectively.
