Color fastness is a crucial quality parameter for textiles, indicating how well a fabric retains its color when exposed to various environmental factors like washing, light, rubbing, and perspiration. Improving color fastness ensures that fabrics maintain their aesthetic appeal and functionality over time, making it essential for manufacturers and consumers alike.

There are many factors that affect color fastness, and there are many ways to improve color fastness, such as selecting appropriate dyeing and chemical additives, improving dyeing and finishing processes, and strengthening process control.


Improve color fastness to washing

1.Thoroughly soaped (cellulose fiber reactive dyes)

2.Reduction cleaning (polyester disperse dyes)

3.Wash with water and adjust the dyeing temperature or heat preservation and color fixing time.

4.Choose high-fastness dyes (for example, when dyeing cotton, consider using high-temperature dyes or vat dyes)

5.Strengthen color fixation after dyeing

6.Reduce the surface friction coefficient of the fabric (for example, remove hairiness from the surface of cotton fabrics by enzyme washing to reduce the surface friction coefficient)

7.Rubbing fastness improving agent (generally can be added when styling)
