The ready-made clothes composed of different color parts sometimes migrate from one area to another during storage, usually from dark color part to light color part. This phenomenon is different from sublimation, because it is carried out at a temperature lower than sublimation temperature, and this phenomenon also occurs for non sublimating dyes. It is mainly reflected in the migration of polyester and other chemical fiber fabrics, as well as other raw materials.
The color transfer is mainly due to two reasons: one is the dye transfer, especially the dispersion, floating color of reactive dyes and the migration of free dyes within the fiber, which may dye the fiber on the surface of another sample; In particular, the dark color dyes the light color, so that it stays on the surface of another sample in the form of granules and impressions. Second, the fiber fell off under the action of friction and was transferred from one sample to another.
