摘要：

为了探讨紫花地丁提取物作为植物染料对改性纯棉针织物的染色性能,对染色方法和染色工艺参数(硫酸亚铁用量、染色pH值、温度和时间)进行优化,对染色牢度、抗紫外线性能和抗菌性能进行测试。结果表明,紫花地丁植物染料纯棉针织物染色以同浴媒染法为好,适宜的染色工艺为:天然染料紫花地丁20 g/L,硫酸亚铁用量2%(o.w.f),柠檬酸0.5 g/L,pH值为6,90℃染色50 min。染色织物耐皂洗和耐摩擦色牢度达到3级及以上,在棉织物上的日晒牢度优于大多数天然染料,可达到3级。经20次水洗后UPF值仍大于50。染色织物对大肠杆菌抗菌率77.03%,对金黄色葡萄球菌抗菌率73.88%。

Abstract:

In this study, the Chinese herb viola philippica extract was selected as a natural dye to treat the knitted cotton fabric. The dyeing properties of the modified knitted cotton fabric, the dyeing methods and dyeing process parameters (dosage of ferrous sulfate, pH value, dyeing temperature and dyeing time) were optimized. The color fastness, UV resistance and antibacterial property of the dyed fabric were evaluated. The results showed that the one-bath mordant dyeing method was the best for the dyeing of knitted cotton fabric by the natural dye viola philippica. The optimal dyeing process was determined as follows: viola philippica 20 g/L, ferrous sulfate 2%(o.w.f), citric acid 0.5 g/L, a pH value of 6, 90℃ for 50 min. Under this condition, the color fastness to soap washing and friction of the dyed fabric reached level 3 or above. The color fastness to sunlight on cotton fabrics was better than most natural dyes and reached 3 level. The UPF value was still higher than 50 after 20 laundries. The antibacterial rates of the dyed fabric against Escherichia coli and Staphylococcus aureus were 77.03% and 73.88% respectively.
