The Significance of Testing Yarn Strength
During weaving, yarns are subjected to many complicated mechanical actions. For example, when woven in circles, they are subjected to tension, bending, and torsion. At the same time, the yarn will be subjected to different forms of friction when winding through the guide parts and its coils. Therefore, the quality of yarn has a great impact on the yield and quality of blasted cloth.
Yarn strength, also known as yarn fastness, is a reflection of yarn quality. Because the yarn has to undergo certain tension and load in the process of production, the yarn must have a certain strength to ensure the normal operation of the knitting process. The yarn strength can be measured by single yarn strength tester, and the index of yarn strength can be divided into two categories: absolute strength and relative strength. Absolute strength refers to the strength the yarn needs that when it is stretched directly to break by an external force, also known as breaking strength, expressed in CN/tex.
Influence Factors of Yarn strength
The strength of a single yarn is always less than the sum of the breaking strength of each fiber in its cross section. The ratio of the two is called the utilization coefficient of yarn strength. The ratio of the single yarn strength is usually 0.4~0.5 for cotton yarn and 0.2~0.3 for woolen yarn. Yarn strength depends on the type, thickness, twist, unevenness, and quality of yarn fibers.
Brief Introduction of Single Yarn Strength Machine
Use the single yarn strength meter to stretch the yarn at a constant speed per minute until breaking, while recording the breaking strength and breaking elongation. The single yarn strength instrument is used to test the breaking strength and breaking elongation and related indexes of all kinds of yarns, such as cotton, wool, hemp, silk, chemical fiber, pure or blended yarn. This machine can be used off-line alone or also can be connected with the computer to achieve two-way communication.
