How to ensure the color fastness of textiles 2022.07.29

Dyeing fastness includes open China fastness, ironing fastness, soaping fastness, perspiration fastness, rubbing fastness, light fastness, etc. The key to these fastnesses is the structural properties of dyes, but also the external conditions. , fiber, dye concentration, dyeing and finishing process, etc. are closely related, so whether the dyeing fastness meets the standard depends on the selected dyestuff, followed by the coloring process and the application of coloring auxiliaries.

When the coloring process is certified, it must be reasonably determined according to the fibers, dyes and customer indicators, so that with the help of auxiliaries, the dyes can be dyed firmly on the fibers under certain conditions, so that they can be fully fixed. For the auxiliaries, one is to choose a good leveling agent and dye accelerator, so that the dye can dye the fiber slowly, uniformly and fully; the other is to add a chelating agent to overcome the complexation of the dye and the metal ions in the water to form floating color, and Reduce the hydrolysis of reactive dyes in water; the third is to choose an excellent soaping agent to remove the floating color and prevent the floating color from re-staining the fabric; the fourth is to choose an appropriate color-fixing agent, which is currently fast to sublimation and sunlight. In addition to the lack of ideal color-fixing agents, there are excellent color-fixing agents for various indicators such as soaping fastness, perspiration fastness, and rubbing fastness.
