What is wet rubbing fastness
In the textile printing and dyeing industry, there are many factors that affect the wet rubbing fastness of fabric. With the development of textile printing and dyeing industry, the quality of textile fabrics such as school uniforms and tooling has been improved, especially higher standards have been put forward in terms of wet friction fastness. For textiles exported to developed countries in Europe and the United States, it is clearly proposed that the wet friction fastness of dark-colored fabrics should reach level 3 or above. However, the wet rubbing fastness of pure cotton yarn and fabric is poor when dyeing activity (especially big red, big black, etc.).
Wet rubbing fastness refers to the rubbing color fastness of dyed fabric in wet state under specified conditions and time.
The role of wet friction fastness enhancer is to form a protective film by interacting with the negative ions on the fiber surface during textile processing, so as to improve the wet friction fastness of the fiber surface and prevent the pigment on the fiber surface from being worn and faded.
What factors affect wet rubbing fastness
1, the directness of the dye can not be too high, the general color fixing rate F is less than 70%, E-F value is greater than 15% of the reactive dye, its floating color is difficult to remove, not suitable for deep color. 2, the concentration of dye used for deep color dyeing is high, and the amount of floating dye is increased. The adsorption of the fiber to the dye has a saturation value, and the dye concentration should not exceed the dyeing saturation And 10% of the value, excessive dye can not be dyed and fixed, will accumulate on the surface of the fabric, thereby affecting the wet friction fastness of the dye. 3, the smoother the surface of the fabric, the higher the wet friction fastness, so the singeing should be net, and the colored fiber particles should be reduced. 4. The gross effect of dyeing semi-finished products directly affects the permeability of dyestuff when dyeing, the better the permeability, the better the diffusion of dyestuff to the interior of the fiber after dyeing, which is conducive to reducing dyeing Material accumulates on the surface of the fabric. 5, adding penetrant and mercerizing treatment, are conducive to improving the wet friction fastness.
