The gray cards currently in use include AATCC gray cards, ISO gray cards, JIS gray cards and national standard GB gray cards. The Color Fastness of textiles is graded by discoloration and staining gray cards. The second is that the fibers fall off under the action of friction and transfer from one sample to another. This usually happens with dark colors that dye light colors and stay on the other sample’s surface in a granular and embossed form. These dyes may migrate and be released from the fiber, dyeing the fiber on another sample’s surface. The color transfer is mainly due to two reasons: the first is the transfer of dyes, especially the floating color of dispersing and reactive dyes. We can see this in the migration of dyes in polyester and other chemical fiber fabrics, as well as other raw materials. This phenomenon is different from sublimation because it is carried out at temperatures below sublimation temperature, and it also occurs with non-sublimation dyes. Staining is a phenomenon where part of the dye on a piece of fabric is separated from its originally attached fiber and transferred to other lining fabrics when placed under various environmental factors, thereby staining the lining fabric.įor garments composed of parts with different colors, dyes sometimes migrate from one area of the fabric to another, during storage and usually from dark parts to light parts. Some of these occurrences within textiles include when part of the dye is separated from the fiber, or the luminescent group of the dye is destroyed, or a new luminescent group is generated. This effect is referred to as discoloration. In printing and dyeing textiles under specific environmental factors, certain activities and reactions within the textile may result in color chroma, hue, and brightness changes.
