弱酸性山德兰MF染料染羊绒绞纱大小样色差的研究

A Study on Color Difference between Lab Samples and Bulk Samples of Cashmere Yarn Dyed with Sandolan MF Acid Dye

染色大小样色差是困扰染色生产的最主要问题。染色大小样不符的一个重要原因就是大小样染色工艺差异太大。本文以羊绒绞纱染色为例,主要从染色工艺方面着手,通过正交试验设计方法,找出影响羊绒织物绞纱染色大小样色差的最主要因素,调整出合理的工艺参数,制定出符合企业生产的优化的工艺曲线,最终达到减少绞纱染色色差的目的。

Color difference between lab samples and bulk samples is the most important question in the dyeing production. The difference of dyeing process is an important reason of color difference between lab samples and bulk samples. This article took the cashmere yarn dyeing as an example, beginning from the dyeing technological aspect, the optimum technological parameter was determined through orthogonal experiment design method,the most primary influence factor were found,the reasonable technological parameters were given. he optimum technology which was adapt to enterprise production was determined,yarn dyeing color difference was reduced finally.
