Color migration problems such as discoloration, staining, and color mixing have plagued users for a long time. The processed textiles undergo storage stacking pressure, transportation temperature changes and other factors, which lead to the movement of dye molecules from the fabric to the fabric surface, which reduces the color fastness of the fabric and seriously affects the quality of the textile. Inkbank high sublimation fastness ink uses high temperature disperse dyes, which can effectively improve the sublimation fastness of the ink, and can solve the color migration problems such as discoloration, staining and color mixing after the fabric is transferred. The ink has the characteristics of simple use process, strong stability, good fluency and excellent imprinting performance.
