Prediction of yarn breakage on ring frame by failure mode and effect analysis using fuzzy logic

Abstract

In a textile mill, spinning is one of the most important processes in the production line which is the heart of the production. Ring spinning is the most widely used spinning technology today because it is universally applicable that is to say can spin all. kinds of yarn, its flexible regarding product types and qualities, easy to operate and delivers yarn with good characteristics. One basic way to increase profit and quality in the ring spinning process is to keep the end breakage rate to a minimum level. The end breakage rare is a critical spinning parameter that not only affects the maximum spindle speed but may also indicate the quality of yam, the mechanical condition of the. machine and the quality of raw materials. Therefore, it is an important parameter which determines the overall working of a spinning mill. Generally, two approaches have been used in studies to predict yam breakage on the ring frame theoretical approaches and statistical approaches.
