全棉毛巾织物大中样与小样色差的控制

Controlling the Color Difference Between Pilot/Bulk Samples and Lab Samples of Pure Cotton Terry Fabric

印花大中样与小样之间的色差一直是困扰印花生产的一大问题。本文以全棉毛巾织物的活性染料直接印花为例,从织物的选用、前处理过程的注意点、染料的选择、助剂的使用,以及操作工艺的确定等方面,具体介绍了如何获得从化验室小样到中样试制以及批量生产的良好重现性,即大中样与小样色差的控制,努力提高印花质量及生产效率。

Color difference between Pilot/Bulk samples and lab samples has been a major problem haunted printing production.By taking pure cotton terry fabric directly printed with reactive dyes as an example,the article briefs thetips of printing process and analyzes the color difference between lab samples and I pilot/bulk samples. It introduces in details how to obtain good reproducibility from lab to bulk production and how to improve printing quality and productivity.
