【摘要】 本文以未防缩的染色羊毛绒线作为标样,测定先染色后氯化羊毛绒线与先氯化后染色羊毛绒线的色差并进行对比分析,研究了防缩整理剂迪兰DC对国产弱酸性、中性染料和酸性媒介染料染色效果的影响。试验表明一般先染色后氯化变色小,但得色淡;先氯化后染色变色大,但得色浓。有些染料防缩整理后颜色变化很大,不适合用于防缩整理羊毛的染色。更多还原

【Abstract】 In this article, dyed knitting wool without felt-proofing was taken as a standard sample and the comparison of the colour differences between two kinds of knitting wool was made, of which the one was dyed prior to chlorinated and the other was chlorinated prior to dyed. It is studied how the felt-proofing agent DC affects the dyeing results with homemade weakly acid dyes, neutral dyes and acid mordant dyes. In post chlorinating process, less discolouration was obtained but lowered colour yield, whereas more discolouration but deep shades in post dyeing process. This paper stresses that some dyes are not suitable for knitting wool dyeing due to their utmost colour change after felt-proofing.更多还原
