Study on Waste Generation in Single Jersey Circular Knitting Machine

Abstract

The textile factory in Bangladesh, especially the knitwear industries, where a huge amount of knitted fabric is produced daily. There are also many kinds of raw materials such as yarns, different kinds of titration are used depending on the production needs. So in this aspect, though the production procedure is same for different knit products, major different are seen during the time of production I has often been seen that the amount of fabric produced is slightly less than the amount of incoming yarn. . It was remembered as the so-called loss of process. Now the question is,what is the reason for this loss process and how much in weight of yarn wasted during production. To find the answer to these questions, we have seen that the loss of process is influenced by certain factors during production, such as yarn types, yarn composition, yarn count, yarn brand, yarn bundle, m / c r.p.m. operator skill, thread tension, thread load, relative humidity, etc. All necessary data was collected throughout the day beyond 12 hours per day (1 shift) and was collected and reorganized as a Microsoft trading word. And it has been shown that this thesis uncovers the loss of process for each of the criteria at the same time for each of the individual machines. Through this thesis it is clear that the waste of yarn is more important in the case of a foreign brand than in the case of a local brand during knitting.
