Abstract

At present, many well-known brands of washing machines in the market are equipped with dye transfer inhibition washing procedures. However, there is no standardized sample available for the evaluation of the dye transfer inhibition washing procedure, and there is no comparability and access standard of the high-quality washing machine with the related functions. In this article, the certified reference materials for the evaluation of the dye transfer inhibition function will be prepared, which consist of certified reference material of white cotton fabric and that of dyed cotton fabric. The certified reference material of white fabric is made of bleached plain fabric, and that of dyed fabric is made with different reactive red dyes and dyeing processes. The size and manufacturing process of the whole set of standardized samples for the evaluation of dye transfer inhibition are selected and determined through experiments. The preparation of the standardized sample for the evaluation of dye transfer inhibition will improve the research and design of the functional washing procedure, which can better solve the pain point when dark and light clothes are washed together.

Highlights

Cotton clothing is preferred by consumers because of its comfortable and breathable characteristics.[1]
The dyeing uniformity analysis of the 96 dyed fabric samples taken was used to discuss the rationality of the certified reference materials (CRMs) of the dyed fabric preparation process proposed in this experiment
After we completed the operation of the above color difference test method, we calculated the standard deviation of the 32 color difference data corresponding to the eight dyed fabric samples prepared under each dyeing process, which was used to evaluate the uniformity of dyeing

Summary

Introduction

Cotton clothing is preferred by consumers because of its comfortable and breathable characteristics.[1] Reactive dyes are widely used in the dyeing of cotton fabrics due to their wide color spectrum, bright color, and strong applicability.[2] It is precisely because people prefer cotton clothes and their fascination with colors that clothes of various colors appear on the market. Those dark natural fiber fabrics are more prone to fading. According to GB/T15000.3-2008 “Directives for the work of reference materials (3)—Reference materials—General and statistical principles for certification[11] (in Chinese),” the experimental scheme is designed to evaluate the uniformity of dyeing, determine the dyeing process of standardized samples, and carry out the experimental scheme design of distinguishability and feasibility
