纤维素纤维KN型活性染料最优化染色技术

Optimized Dyeing of Cellulosic Fibers with KN Type Reactive Dyes

纤维素纤维KN型活性染料浸染工艺中,由于促染剂无机盐类的加入和固色剂碱剂的加入均会造成染料自身的凝聚,从而造成染色不匀、染斑等病疵。可以通过特殊助剂的加入,并采用一次投料工艺,有效地解决了出现的问题,并达到了简易快速的加工目的。

During exhaust dyeing of cellulosic fibres with KN reactive dyes, the addition of inorganic salt as promoter and alikaline agent for fixation often leads to aggregation of the dyes and results in dye defects such as unevenness and dye specks. This paper has effectively solved these problems by adopting one-bath process and using special auxiliary and a simple and fast dyeing technique is offered.
