TESTEX Textile Test Instrument

  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 dyeing is an essential process for textile processing. Mastering the basic knowledge of textile dyeing and understanding the properties and of common dyestuffs and dyeing methods can help us to select and use dyestuff reasonably, develop the dyeing process correctly for dyeing processing and obtain high-quality dyed textiles. Textile Dyeing Basics 1 What is textile dyeing? Textile dyeing is the process of dyeing textiles products into colored objects by using physical or chemical methods to allow dyes to bond with fibers. Dyeing requirements: uniform dyeing with good color fastness. 2 Dyeing principle: color properties of dyes Dyes have chromophore and auxochrome in their molecular structure, which selectively absorb visible light. When the chromophore and the auxochrome are different, the dyes absorb light differently, and therefore, different dyes have different colors. In addition to differences in hue, the colors of dyes also differ in brightness and saturation. Hue i...
