Abstract

In this work the yarn tension was measured during withdrawing the yarn from stationary cops. The value of yarn tension was measured under the effect of the following parameters: - Distance between cops and yarn guide (without using balloon breaker) - Type of balloon breaker - Linear density of yarn The value of yarn tension during direct unwinding from cops can be reduced by varying the distance between cops and yarns guide. It was found that the small distance between cops and yarn guide is suitable, since the level of yarn tension is low. In case of using balloon breaker the value of yarn tension can be reduced by using a balloon breaker with triangular cross section.
