摘　　要：木质素磺酸钠来源于工业生产中的废弃物木质素,在印染行业中经常用做分散剂,但在使用过程中对纤维有沾色现象。文中研究木质素磺酸钠对羊毛的着色情况,从温度、时间、pH值以及浓度等方面对木质素磺酸钠上染羊毛的条件进行探索,并测试染后织物的色牢度、耐洗涤、强力、防紫外线等性能。结果表明,木质素磺酸钠在pH值2.0~4.0、用量大于30.0%、90℃的条件下能将羊毛织物染成深色,着色60min后织物的K/S值在6.00以上;并且着色羊毛织物强力损伤较低,试验范围内不同pH值的染浴得到的织物强力损伤都在10%以内;对紫外线也有较好的过滤效果。Sodium lignosulfonate is derived from lignin waste,and is often used as a dispersant in the printing and dyeing industry,but they stain fibers.In this paper,the dyeing of wool by sodium lignosulfonate was studied,and the conditions of dyeing with sodium lignosulfonate were detailed studied from the aspects of temperature,time,pH value and concentration.And the color fastness,washing resistance,fabric strength,UV resistance and other properties of the dyed fabrics were also tested.The results show that sodium lignosulfonate can dye wool fabric into a dark color at pH 2.0~4.0,30.0% and 90 ℃.The K/S value of fabric after dyeing for 60 minutes reaches above 6.00.Moreover,the strength damage of dyed wool fabrics is low.The strength damage of fabrics dyed under different pH values are all less than 10%.It also has a good effect of anti-ultraviolet.
