Computerized Lea Strength Tester TY410
Computerized Lea Strength Tester, to determine the strength and elongation of skein yarn.
Lea Strength Tester, to determine the strength and elongation of skein yarn.
The lea strength of yarn is one of the major properties on which the suitability of yarn for its ultimate end use depends. The test for determination of lea strength consists of making a lea from the yarn with the help of a wrap reel and testing it on the lea strength tester, which registers the maximum load at which the lea starts unraveling.

What is the Testing Significance of Lea Strength Tester?
The tensile property index of yarn is one of the main bases for evaluating yarn grade. It is of great significance for yarn production, weaving process, and production efficiency. The index of yarn tensile property mainly refers to yarn strength and yarn elongation at break.
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 is subjected to tension, stretching until it is broken, the percentage of the elongation length to the original length is called elongation at break of the yarn. Yarn with good elongation can buffer the effect of external force and reduce the break rate in the production process.
The upper and lower grippers of the lea strength tester are used to clamp the two ends of the specimen and stretch the sample at a constant rate until the specimen was broken. Because the gripper and the force sensor are closely combined, the force on the gripper is converted into the corresponding digital signal and processed by the force sensor. The instrument can record the technical indexes such as breaking strength and elongation at break. After the test, the statistical value of the technical index will be given by the data processing system.
