Strength of wet spliced denim yarns after sizing using a central composite design

The retained strength of wet spliced yarns can be controlled to some extent by suitable choices of certain factors related to the process. In order to understand how these variables influence the breaking force of wet spliced yarns, a central composite design was formulated and three variables - yarn count, the duration of air joining and the duration of water joining - were considered. Analysis of the results indicates that yarn count and length of splice contribute significantly to this mechanical property of wet sized spliced yarns. The duration of water joining, the duration of air joining of splice and the recipe size have a considerable effects.
