分散染料染二醋/涤纶/氨纶混纺织物工艺研究

Study on Dyeing Diacetate/Polyester/Spandex Blended Fabric with Disperse Dyes

借助计算机测配色技术,筛选了染二醋/涤纶/氨纶混纺织物的分散染料,研究了染色工艺,并测试了织物的各项色牢度。结果表明:38%二醋/57%涤纶/5%氨纶短纤纬编面料,使用ECF型、SWF系列及HSF系列分散染料拼色,分别在110℃染浅色和120℃染中深色,后处理加入助剂RCL,织物颜色与标样色光相近、强度相似;在深色染料拼色时加入抗还原剂HWF能提高分散染料的得色率;织物各项色牢度基本符合生产要求。

Disperse dyes for dyeing diacetate/polyester/spandex blended fabries were screened under the assistance of computer color matching system,dyeing processes were studied,and various color fastness of the fabric were tested.The results showed that the 38%diacetate/57%polyester/5%spandex staple fiber weft kited fabric dyed with ECF type,SWF series and HSF series disperse dyes for color matching,lighut colors dyed at 110℃ and medium dark colors dyed at 120℃,respectively,and afer treatment with auxiliary RCL being added,and the fabrie color and stength were similar to the slandard sample.Adding HWF during color matching of dark dyes can improve the color yield of dispersed dyes.The color fastness of the fabric basically meets the production requirements.
