Study of Elongation at Break for Twisted Aluminum Oxide Yarns with Full Factorial Experimental Design for Twist Optimization

Аннотация

Articles for technical use made from twisted aluminum oxide yarns are promising for application in various areas of industry. With the aim of improving the characteristics of the mechanical properties, multifilament yarns are twisted with the needed number of plies. We used a full factorial experimental design to obtain a regression equation reflecting the dependence of the yarn elongation under tension up to break vs. twists for yarns of linear density 10 tex into two plies and then five plies. The study results show that by varying the degree of the first and subsequent twists, we can change the elongation under tension up to break of twisted aluminum oxide yarns in certain ranges.
