分散染料对超细涤纶的染色 摘 要 超细涤纶纤维具有优异的强度、尺寸稳定性、洗可穿、手感丰满、柔软、飘逸等独特的风格，是普通涤纶纤维无法相比的。超细纤维在赋予织物优异服用性能的同时,其在染整加工技术方面面临着合成纤维所未遇到的新问题,突出表现为匀染性差、色泽浅和色牢度低等。本文针对超细涤纶针织物所用染料在染色性能方面进行研究,通过筛选提出了适合于超细纤维染色的染料及其染整加工的最佳工艺, 经过试验,SE型分散染料符合要求。文中介绍了pH、时间、浴比对染色性能的影响。对生产实践具有指导意义。 关键词：超细涤纶纤维 分散染料 Dispersal dyes of ultrafine polyester dyeing ABSTRACT Super fine polyester fiber of excellent strength, size stability, wash to wear, feel is plump, soft, elegant, and other unique style, is ordinary polyester fibers that cannot be compared. Superfine fiber fabric in excellent using properties to at the same time, its in dyeing processing technology faced with synthetic fiber have not met the new problems, outstanding performance for levelness sent, colour and lustre is shallow and low color fastness. This paper is focused on the fine polyester knitted fabric used dyes in the dyeing performance, through the screening was put forward for the fiber dyeing of dye and the pulverisation of dyeing and finishing the best process, through test, SE type disperse dyestuffs meets the requirement. This paper introduces the pH, time, bath dyeing performance than influence. Has a guiding significance to the production practice.
