Preparation of certified reference materials for cotton fabric's dye transfer inhibition performance test of household washing machines.

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.
