Rubbing fastness is one of the most important indexes in the color fastness of textiles, that is, the degree of fading of dyed fabric after friction, which can be divided into dry and wet rubbing. Rubbing fastness to the color of white cloth as the evaluation principle, a total of 5 grades (1-5), the larger the value, indicating the better the rubbing fastness. The factors affecting the fastness to wet rubbing in textile products are: the types of fabrics, fabric structure, textile pretreatment, such as desizing, scouring, bleaching, mercerizing, etc., the choice of textile dyes and the process, temperature, time control strict or not, as well as the selection and use of  textiles auxiliaries , and post-treatment, etc. Reactive dyes with bright color, complete chromatogram and low price are important dyes for cotton, but the wet rubbing fastness relatively low in dyeing medium and dark colors. At present, improving the wet rubbing fastness of reactive dyes mainly by selecting suita...

1.  Color fastness of rubbing: rubbing fastness is said to be the fading degree that dyeing textile goes through, it can be divided as dry friction and wet friction. Rubbing fastness is based on dyeing degree of white cloth the as evaluation criterion, which is 5 levels. The bigger value is the better the rubbing friction is.( a series of products of wet friction in our company)  2. Color fastness of lightening: lightening fastening means the degree of discoloration that dyeing textile is influenced by daylight effect. Its testing method is to compare the fading degree of samples with standard color swatch by means of modeling the process of daylight. It can be divided into 8 levels, among which the eighth degree is the best while the first one is the worst. The textile with poor lightning friction should be avoided exposing under the sun for a long time, and it should be placed in the ventilation where will help to dry in the shade.( our company’s light fastness improver) 3. ...

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...
