摘　　要：采用活性染料对羊毛织物进行冷轧堆染色,以K/S值为评价依据,以确定羊毛活性染料冷轧堆染色的优化工艺,即尿素100g/L,亚硫酸氢钠20g/L,pH值4.5～6.5,堆置时间24h,轧余率110%。染色后的羊毛织物具有较高的固着率、匀染性和透染性,染色牢度达4～5级以上,断裂强力和断裂伸长损失控制在15%以内,撕破强力损失控制在20%以内。Cold pad-batch dyeing process of wool fabric with reactive dyes was carried out. On the basis of K/S value evaluation, the optimum conditions were defined as followings： urea 100 g/L, sodium bisulfite 20 g/L, pH value 4.5 - 6, 5, batching time 24 h,pick up 110%. The result showed that the dyed fabrics had good fixation,levelness and penetrating property,color fastness was above 4 - 5 grades,the loss for breaking strength and breaking extension was less than 15%,the loss for tear strength was less than 20%.
