摘要:采用活性荧光黄FL 对纯棉和65/35涤棉混纺针织物进行染色,

探讨了染色温度、时间,纯碱、氯化钠和染料用量对上染率、固色率和K /S 值的影响,分析了染色织物的荧光效果,测试了染色织物的色牢度。研究结果表明,活性荧光黄FL 对纯棉和涤棉织物的最佳染色工艺为:纯碱10g/L ,氯化钠50g/L ,60℃保温60min ;活性荧光黄FL 用量超过4%(omf)时,染色棉织物可满足警示服的荧光要求,但非荧光活性染料的加入对染色棉织物的荧光强度影响很大;涤棉织物在1%~20%(omf)的染料用量范围内未满足警示服的荧光要求。荧光染色棉和涤棉织物具有较好的耐皂洗和耐摩擦色牢度。

Abstract:The Reactive Fluorescent Yellow FL was applied to dyeing of cotton and polyester/cotton blend

fabrics.The effects of dyeing temperature,time,dosage of sodium carbonate,sodium chloride and reactive dyes on exhaustion,fixation rate and K /S value of dyed fabrics were discussed.The fluorescence effect of dyed fabrics was analyzed,the color fastness of the dyed fabrics were also tested.The results showed that the optimal dyeing process was sodium carbonate 10g/L,sodium chloride 50g/L,dyeing at 60℃for 60min.The dyed cotton fabrics reached the fluorescent effects of warning clothing needs by dyeing with above 4%(omf)Reactive Fluorescence Yellow FL,and the addition of non-fluorescent reactive dyes influenced the fluo ?rescent effects obviously.The dyed polyester/cotton fabrics could not reach the fluorescent effects of warning clothing needs by dyeing with 1%~20%(omf)Reactive Fluorescence Yellow FL.The washing and rubbing fast ?ness of fluorescence dyes dyed cotton and polyester/cotton fabric was good.

Key words:reactive fluorescent dyes;disperse fluorescent dyes;cotton fabric;polyester/cotton blend

作者简介:曹机良(1982-),男,湖南湘阴人,讲师,在读博士,主要从事纺织品染整工艺与理论,纺织品功能整理方面的研究。传统染料只要求有好的色牢度、色光,而在一些

特殊领域(如消防)则要求染料有一些特殊的性质

(如警示作用)。荧光染料是一种特殊的功能性染

料,既具有常规染料的染色性能,又能发射出荧光,

有意想不到的警示效果[1-2]。荧光面料不仅用于具有

安全警示防护作用的职业服装面料,也用于对服装

面料鲜艳度等具有特别要求的普通服饰,提高制品的美学价值[3-4]。目前,市场上用于棉织物染色的荧光色素主要为荧光涂料,但涂料染色织物往往存在耐摩擦色牢度和手感不佳的问题。活性荧光染料市场化的只有活性荧光黄FL ,关于活性荧光染料对棉的染色有少量报道,但没有关于活性荧光染料对涤棉荧光性能影响的报道[5]。针对上述问题,本文采用活性荧光黄FL 染色棉棉和涤棉混纺织物活性荧光染料染色
