What is fabric abrasion resistance Fabric abrasion resistance refers to the fabric's resistance to wear and tear. Abrasion refers to the phenomenon that fabrics are gradually damaged due to repeated friction from other objects during use. The abrasion resistance of…
The rotational viscometer is a digital viscometer. The motor drives the rotor to rotate at a constant speed through variable speed. The casing of the motor is mounted in a suspended manner, and it drives the drum to rotate through…
Definition of viscosity Viscosity refers to the resistance a fluid exhibits to flow. When a fluid (gas or liquid) flows and one part flows over another, it encounters resistance, which is the internal friction of the fluid. To make the…
The Martindale abrasion tester (Martindale method) is used to test the abrasion resistance and apparent pilling properties of woven fabrics, knitted fabrics, non-woven fabrics, decorative materials, coated fabrics, etc. Working principle The fabric to be tested is mounted in the…
Spinning, as an engineering technology, processes fiber aggregates, and its essence is the process of changing fibers from a chaotic state into an orderly arrangement in the longitudinal direction. Currently, the commonly used spinning raw materials are mainly natural fibers…
During the wearing process, clothes are constantly subjected to friction, causing the fiber ends on the surface of the fabric to be pulled, belted, hooked, and pulled out, and the phenomenon of hairiness forming on the surface of the fabric…
People have demands for water repellency and water-conducting fabrics. The water conductivity and comfort of the fabric can be seen from the wettability of the fiber surface; the waterproof performance of the fabric can be enhanced by waterproof treatment or…
Definition and overview of universal testing machine The universal testing machine is also called a tensile testing machine. It is an instrument used to conduct static load, tensile, compression, tearing, peeling and other mechanical property tests on various materials. It…
The melting point is the temperature at which a solid changes (melts) its physical state from solid to liquid. The temperature at which the opposite action occurs (ie, changes from liquid to solid) is called the freezing point. Unlike boiling…
Air permeability is a widely used test that measures the ease with which air can pass through a fabric and helps to indicate the air permeability of the fabric, especially for wind-proof, weather-resistant, and water-resistant fabrics. YG461F Fully Automatic Air…
The hydrostatic pressure resistance index is one of the most important indicators of waterproof and breathable fabrics. Hydrostatic pressure refers to the resistance water encounters as it passes through fabric. Under standard atmospheric pressure conditions, the fabric is subjected to…
Fabric dimensional stability refers to the shortening or elongation of fabric length during wearing, washing, storage, etc. Among them, shrinkage is one of the most concerning phenomena. The shrinkage of the fabric not only affects the appearance of the fabric,…
