In textiles, the rubbing fastness of wet and dry fabrics is tested according to various standard specifications. The purpose of these tests is to determine the color fastness to rubbing of all types of textile materials. Usually color fastness is expressed in grey scales. AATCC Rotary Vertical Crockmeter is designed to in eliminating any subjective effects on load and friction rate that might affe...

In the process of wearing clothes again, they are constantly rubbed, so that the fiber ends on the surface of the fabric are pulled, belted, hooked, pulled out, and the phenomenon of hairiness formed on the surface of the fabric is called fluff...
Clothes are prone to pilling due to abrasion during wearing, so the abrasion and pilling resistance of the fabric is particularly important. Generally, fabrics with high abrasion and pilling resistance have good strength, wear resistance and elasticity. Fabrics with high abrasion and pilling resistance include wool, cashmere, silk, polyester and nylon. In addition, some fabrics are specially treat...
