棉/毛混纺纱一浴法染色

One-bath process dyeing for cotton/wool blended yarn

采用Lanasol系列和LS系列染料进行染色,在染色前加入自主研发的特种助剂YDR对棉/毛混纺纱线进行预处理,提高了棉纤维对活性染料的亲和力,从而有效地解决了棉/毛混纺纱染色时棉浅毛深的难题,使其具备了很好的同色性。对助剂YDR处理工艺的条件、LS系列染料染色条件等进行了研究,最终制定出了一整套新的YDR处理和一浴法染色新工艺。

The Lanasol dyes and LS dyes were chosen for dyeing stuffs in this essay.By adding the special auxiliary YDR developed independently before dyeing to give the cotton/wool blending yarn pretreatment,the affinity between reactive dye and the cotton fiber was increased.Thus the problem of light colored cotton and deep colored wool in dyeing the cotton/wool blending yarn was resolved,and the yarn was imparted a good homochroma.The treating condition of the yarn by auxiliary YDR,the dyeing condition by Lanasol dyes were studied here.Finally a whole new set processing of the YDR treating and one-bath dyeing process were concluded.
