酸性荧光黄73对羊毛织物的染色

Dyeing of wool fabric with acid fluorescence yellow 73

采用酸性荧光黄73对羊毛织物进行染色,探讨染色pH值、染色温度、染色时间、电解质NaCl浓度、染料用量对羊毛表观色深K/S值的影响,分析染色织物的荧光效果,测试染色织物的牢度。研究结果表明:染色织物的K/S值随着染色温度的升高和染色时间的延长而逐渐增加,随着染色pH值和NaCl用量的增加染色织物的K/S值逐渐下降,染色织物具有一定的荧光强度,可满足除警示服外的其他服饰的荧光要求;酸性荧光黄73用量为2%(owf)时,对羊毛的最佳染色工艺为:染色pH值5,染色温度高于80℃,染色时间40 min;且染色织物具有较好的耐洗和耐摩擦牢度。

The acid fluorescence yellow 73 was applied to dyeing wool fabrics. The effects of the dosage of dyes,sodium chloride,pH value and dyeing temperature and time on K / S value of dyed wool fabric were analyzed. The fluorescence effect and color fastness of dyed wool fabrics were investigated. It was found that,the K / S value of wool fabrics increased with the increasing of dyeing temperature and dyeing time,but decreased with the increasing of dyeing pH value and dosage of sodium chloride,and the dyed fabric have some fluorescent effect can reached for clothing needs. When the dosage of acid fluorescence yellow 73（was） 2%（owf）,the optimal dyeing process was pH 5,dyeing at 80 ℃ for 40 min,and the washing and crocking fastness of dyed fabrics were good.
