The crease recovery property of fabric is one of the important indexes to evaluate the properties of fabric. Measuring the crease recovery Angle of folded fabric samples by instrument is a common method to measure the crease recovery property of…
When fabrics are worn or used, they are often subject to concentrated loads perpendicular to the plane of the fabric. The fabric bulges and expands from one side until it breaks, such as at knees, elbows, shoe uppers, glove fingers,…
Fabric tear test is mainly used to test the tear resistance of film, sheet, soft polyvinyl chloride, polyvinylidene chloride (PVDC), waterproof coil, braided material, polyene warp, polyester, paper, cardboard, textiles and non-wovens. Tear strength test method Impact pendulum method Suitable…
An extensometer is an instrument that measures line deformation between two points on components and other objects. The main equipment used in tensile testing includes testing machines and extensometers. The testing machine is a system that applies tensile testing force…
The phenomenon of fibers and yarns in textiles being pulled out of the fabric surface due to hooking is called snagging. When knitted fabrics and textured filament woven fabrics encounter hard objects during use, snagging can easily occur, and yarn…
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…
