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...

  This article is developed from four aspects: the basics of fabric shrinkage (definition, principle, common sense), the factors affecting fabric shrinkage, the test method of fabric shrinkage, and how to textile fabric shrinkage during the washing and care process. This should be the most comprehensive guide on fabric shrinkage. The Basics of Fabric Shrinkage 1 What is the fabric shrinkage? Fabric shrinkage is a textile in a certain state, after washing, dewatering, drying and other processes, the length or width of a change in a phenomenon. Measure the degree of shrinkage index called shrinkage rate or shrinkage, the type of fiber, the structure of the fabric, weaving and processing of external forces, etc. will affect the shrinkage performance of the fabric. 2 The principle of fabric shrinkage After the fiber absorbs moisture, its longitudinal and transverse are to swell, the volume increases, of which the transverse expansion is large and the longitudinal expansion is small. Th...

  Textile hydrostatic pressure refers to the resistance encountered when the water penetrates the fabric. Under standard atmospheric conditions, the fabric is subjected to a continuous rise in water pressure until water droplets seep out from the back of the fabric, at which point the measured water pressure size is the textile hydrostatic pressure. Common test standards are: ISO 811, AATCC 127, JIS L 1092. Comparison of textile hydrostatic pressure test methods In the textile industry, fabric hydrostatic pressure testing is widely used and has an important impact on functional textiles, and there are currently many different ways to test hydrostatic pressure. Classification by test method 1 Field testing Field testing is expensive and takes a long time, usually about six months. During the experimental period, the water resistance of the fabric is tested periodically after the waterproof and moisture permeable finishing, so that the durability can be known. Although this method is...
