AI Technical Summary
Ammonia-free elastic fabrics are prone to problems such as color spots, color differences, edge wrinkles, claw marks, and color creases during the dyeing process. Existing technologies are difficult to effectively control the dyeing rate and uniformity, resulting in unstable dyeing quality.
A high-temperature acid-adjusting dyeing method is adopted, with temperature and pH value controlled in stages. The uniform feeding rate is achieved by adjusting the valve opening in real time. Combined with the use of dispersants and leveling agents, the dyeing process is optimized to ensure that the dye enters the fiber uniformly.
It effectively reduces color spots, color differences and wrinkles during the dyeing process, improves dyeing uniformity and quality stability, and enhances the color fastness of dyed fabrics.
