Friction in Textile from Fiber to Fabric

The frictional properties of fabrics are important in the determination of degrees of roughness, smoothness and other surface characteristics. Fabric friction is an important factor in determining the abrasion resistance, shrinkage and esthetic properties. The frictional properties of fabrics are sensitive to variations in fiber content, yarn mechanical properties, fabric structure, type of finishing treatments used in each case, as well as to the conditions used during testing. Fabric friction has been accepted for a long time for objective measurement of the surface attribute of degree of smoothness. The use of the traditional parameter, the coefficient of friction, based on the classical Amonton relation, cannot fully and effectively characterize surface behavior. It is, therefore, necessary to evaluate friction in terms of additional parameters based on friction profile.
