摘　　要：针对纯棉绒类织物在活性染料连续轧染工艺中存在条坑异色、绒面色花、绒底色泽差异大的问题,采用安诺素ECO型活性染料湿蒸工艺对全棉抓剪毛织物进行染色。以染料配伍性、染色织物K/S值、彩度值、正反色差等指标为评价依据,通过单因素试验法对染色工艺进行优化,得到最佳染色工艺条件:染料5 g/L;专用助剂10 mL/L;无水硫酸钠50 g/L;碳酸钠40 g/L;汽蒸时间1.5 min。该工艺与焙烘染色工艺相比,生产能耗更低,且所染织物具有染色深度好、布面色泽鲜艳、正反色差显著减轻等优点。Continuous pad-dyeing of cotton pile fabrics with reactive dyes often leads to chromatic difference between the tip and valley of the pile,streak dyeing on the pile face,and shading on the back of pile fabric.For this reason,Anozol ECO reactive dyes were used to dye cotton pile fabrics followed by wet steaming.The dyeing result was evaluated based on compatibility of dyes,K/S value,depth of shade,color difference between the face and back of the dyed fabrics.The optimum dyeing conditions were obtained by single factor tests,i.e.,dye 5 g/L,auxiliary 10 mL/L,anhydrous Na2SO450 g/L,Na2CO340 g/L,steaming time 1.5 min.When compared with the dyeing-curing process,this dyeing method featured lower energy consumption,good dyed depth,brilliant shade,and reduced color difference between the face and back of the dyed fabrics.
