摘　　要：针对棉/涤长丝交织彩条织物涤染深色棉增白染整工艺中棉沾色严重,导致棉组分白度不高的问题,在常规还原清洗工艺中添加Argace L SW-PES 2 g/L,将两步还原清洗改为一步还原清洗;增加低温漂白工序,减少分散染料迁移对棉的沾色;采用不调色光增白剂Argaphor BHT-L代替调蓝紫光增白剂4BK,有效提高棉组分的白度。工艺改进后彩条织物的白度由常规工艺的115.24%提高到了131.03%。In the dyeing process of cotton/polyester filament woven fabric, the cotton will be stained seriously and the whiteness is poor. In order to solve this problem, ArgaceL SW-PES 2 g/L is added in conventional reduction clearing process with one step to replace two-step reduction process, and low temperature bleaching is carried out to reduce the staining of disperse dyes onto cotton, and a brightener Ar- gaphor BHT-L is used to replace brightener 4BK. Compared with conventional process, the improved process can impart cotton component better whiteness from 115.24% to 131.03%.
