Friction : friction refers to the effect of hindering the movement on the contact surface when there is a relative motion or relative movement trend between two objects in contact with each other. Friction can be divided into sliding friction and rolling friction. Abrasion : abrasion refers to the wear and tear caused by friction during the use of the object, thus reducing the user experience of the object and shortening the service life of the object. The main manifestations of abrasion are fading, pilling, cracks, peeling, slurry, and so on. Friction is the most common and unavoidable cause of wear and tear in textile and related industries. Study the friction properties of fabrics, leather, rubber and other materials has important reference significance for improving the abrasion resistance of articles and how to select the raw materials suitable for our needs. Take fabric as an example, abrasion is the phenomenon of damage that when the fabric does repeated friction with other obje
