A single yarn strength provides information about the warping machine and looms efficiency. In order to calculate the combined strength effect of the yarn, the count lea strength product (CSP) of the yarn is calculated. A lea of 120 yards is made using the wrapping reel, and the weight of the lea is determined in order to calculate the yarn count by using the formula: number of hanks/pound. The lea strength is determined by using a lea strength machine that has two jaws, one fixed and the other attached to the load. Using the constant rate of loading(CRL) principle, the tensile strength of the lea can be determined.
