Pay attention to the color fastness of zipper

The color fastness mainly includes the washing and abrasion resistance of the product, and generally refers to the degree of discoloration of dyed fabrics under the action of external factors (extrusion, friction, soaping, rain, exposure, etc.) during use or processing. As a manufacturer, when choosing a zipper supplier, you should pay attention to the three color fastnesses of the zipper: fastness to sunlight, fastness to soaping, and color migration, so as to avoid these problems and improve the quality of clothing. .
