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...

An electronic tensile tester is the product of the linkage of electronic skills and mechanical transmission, fully developed the respective expertise of mechanical and electrical, and then composed of a large fine tensile tester. The tensile testing machine is designed to test a wide range of materials in tension, compression, flexure, bursting, shear, tear, elongation, constant load, elastic, thread slip, peeling and other mechanical properties, with wide measurement range, high accuracy, fast efficiency, and timely display, documentation and printing of the data. Principle and S tructure of T ensile Tester Electronic tensile tester is composed of a measuring system, driving system, control system and other structures. 1 Measuring system of the tensile testing machine 1.1 Measurement of force value The system consists of a force measuring sensor, an expander and a data processing system, and the most commonly used force measuring sensor is a strain gauge type sensor. The so-...
