The problem of yarn breakage during spinning is quite serious, but it is difficult to predict the number of yarn breakages, because the tension and strength of the yarn always vary. The author has used simple mathematical models of the variation of the tension and the strength of the yarn, and calculated the probability of yarn breakages. The result has shown that the variation of the yarn strength influence yarn breakages most. Thus the evenness of the yarn is needed much more than the lower tension on spinning frames to lessen the number of yarn breakages.
