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.
