Brief Talking about Color Fastness

Color fastness, also known as color fastness or dyeing fastness, refers to the degree of fade of the dyeing fabric under the effect of external factors (such extrusion, friction, washing, rain, exposure, light, Saliva dripping, water stains, perspiration, etc.) in the use or processing process. Color fastness is a very important reference indicator for dye products. If color fastness is good, the textile is not easy to fade in the post-processing or use process; if color fastness is poor, textile will fade seriously, colored slightly, or stain, which will affect the appearance and cause a lot of inconveniences. The common questions of about color fastness   1. Color fastness to sunlight The parts of clothing like coat under sunlight will fade or discolor (usually the back and shoulder parts) while other parts don not, resulting in different parts of the product looks different so that the product cannot be used. 2. Color fastness to water cleaning, soaping, and dry cleaning...

How to Improve the Wet Rubbing Fastness of Dye-Sub Fabric

1. Strengthen the pre-treatment, especially the process of boil-out bleaching Using a mild non-caustic oxygen bleaching process(such as oxygen bleach accelerator + H2O2) to avoid the  wet rubbing fastness  affected by fiber brittleness, the rough surface of the fabric and the large friction coefficient of the fabric yarn surface in the process of oxygen bleaching. Strict control of water hardness to prevent the formation of surface lakes, causing the rough feel of the dye, increasing the friction coefficient and decreasing the wet rubbing fastness. The chelating agent, Ca2 +, Mg2 + and other metal ions can be added in the water to decrease the wet rubbing fastness. 2. Fabric can not be boiled with alkali soap after dyeing. Whether use mixed alkali fixation or single Na2CO3 fixation, the fabric must be fully washed with acetic acid 1 ~ 2mL / L in order to achieve fully hydrolysis of flooding, otherwise it will affect the effect of soap washing. 3. Control the quality of soap bo...
