粘锦混纺针织物溢流染色工艺

Overflow dyeing of viscose/nylon knitted fabrics

阐述了粘锦混纺针织物的前处理和溢流染色工艺,认为染浅色织物,可以选择M型、B型活性染料或毛用活性染料进行一浴法染色;中深色品种则采用活性/弱酸性(或中性)两浴法染色工艺。对这类织物染色常见的色花、两相不匀和擦伤等问题,提出了相应的解决方法。

Pretreatment and overflow dyeing techniques of viscose/nylon blended knitted fabrics are introduced. For the lightcolored fabric, dyeing in one bath with M-type, B-type reactive dyes and reactive dyes for wool are proposed. For medium and dark-colored fabrics, reactive/weak acid （or neutral） dyes with two-bath dyeing process are generally used. For common problems such as dyeing defect, uneven dyeing and scratch, and the corresponding solutions are presented.
