The human body can be harmed in different degrees due to the poor quality of some dyes. The color fastness of the fabric is directly related to the test results.The standards are set by different countries and organizations to strictly limit the colorfastness of the home textiles and apparel. This is done to minimize the potential dangers done by the product.
The wet friction will hold the dry fabric which is exposed to the light color. The colorfastness levels are obtained in a better way by the wet fabric. The colorfastness levels are very poor in the printed fabrics. The flocking of the wet and dry friction is almost the same. The results are however not affected by the different test methods.
The pure polyester fabrics are same even though there may be differences in the cotton fabrics. The velvet fabrics are also same under the different friction test methods. The colorfastness is better in the pure polyester fabrics and moist wool fabrics than the dry fabrics.
There is a certain impact on the composition of the raw material of the fabric under the different friction methods. The Crockmeter is one of the basic items to determine the testing for the colorfastness of the textiles. There may be a difference in the data obtained from the test values in different friction.
The color fastness of the fabric refers to the color fastness, which is the dyeing or printing of the fabric in the use or processing process, exposed to external factors, squeeze, friction, washing, rain, exposure, light, sea water immersion, saliva impregnation, water stains, sweat stains under the degree of fade, which is an important indicator of the fabric.
Color fastness, textile processing or use in the process is not easy to fade, poor color fastness, there will be fade, discoloration, or staining, etc., causing a lot of trouble. It can improve the color fastness of light measures. The rational use of dyes, in improving the light fastness, the choice of dye is the key.
Analysis:
The textiles are tested using the different standard methods to determine the colorfastness of the rubbing and then the results are obtained. The dry friction is comparatively better when compared to the wet friction.
The wet friction will hold the dry fabric which is exposed to the light color. The colorfastness levels are obtained in a better way by the wet fabric.
