摘要
用铁观音茶提取液作为天然染料,分别在pH值为3.5、5.5(茶提取液本身pH值)、7.5、9.5的条件下对羊毛织物进行直接染色,并对染色后羊毛织物的抗菌性能进行研究。结果表明:染液pH值对染色后羊毛织物的K/S值和色光均有较大影响,当染液pH值为5.5时,织物的K/S值最大;染色羊毛织物具有良好的耐摩擦和耐洗色牢度,但耐日晒牢度较差,对光照表现出深色效应,随着染液pH值的升高,织物光照变色效应减弱;当染液pH值为5.5时,染色羊毛织物对大肠杆菌和金黄色葡萄球菌的抑菌率最高,分别为98.9%和93.2%;染液酸碱度的提高均会降低染色羊毛织物的抗菌性能,其中碱性染液对其抗菌性的降低作用最为明显。
Tieguanyin tea extract was used as natural dye to dye wool fabrics directly at pH vallues of 3.5, 5.5 （pH of original tea extract）, 7.5 and 9.5. The antibacterial properties of dyed wool fabrics were studied. The results indicated that dye solution pH value has great influence on K/S value and color of wool fabrics. When the pH value of dye solution was 5.5, the dyed wool fabric exhibited the maximum K/S value. The dyed wool fabrics have good rubbing and washing fastness, but poor sunlight fastness. The fabrics became darker under light, and the effect of light decreased as dye solution pH value rose. When dye solution pH value was 5.5, the antibacterial rate of dyed wool fabrics to Escherichia coli and Staphylococcus aureus was highest, at 98.9% and 93.2%, respectively. The antibacterial rate decreased when dye solution was more acidic or alkaline, especially the dye solution was alkaline.
