Strength distribution superiority of compact-Siro spun yarn

Abstract

This study examined the superiority of the strength of compact-Siro spun yarn. First, the strength properties of four types of yarn-ring, compact, Siro, and compact-Siro spun yarn-were compared based on an experiment with 9.7 tex and 14.6 tex polyester yarns. Yarn unevenness and compactness were analyzed in terms of their influence on yarn strength. It was determined that compact spinning enhanced the strength distribution by improving the overall yarn compactness. Siro spinning significantly increased the minimum yarn strength by reducing unevenness. Furthermore, compact-Siro spun yarn, which incorporates the advantages of both compact and Siro, remarkably improved the yarn strength distribution. These results were verified in the first part of the experiment. Finally, the four types of yarn were applied in the same weaving process. The results indicated that the efficiency of weaving with compact-Siro pure polyester yarn was higher than that of other methods by 3%-6%, thereby confirming the superior productivity of the method.

Investigating the effect of different filaments and yarn structures on mechanical and physical properties of dual-core elastane composite yarns

“…The higher the uniformity of the yarns, the higher will be the strength or tenacity of the yarns [ 22 ]. The greater evenness of the siro yarns compared with non-siro ring spun yarns is mainly responsible for the greater tenacity of the siro yarns [ 28 ].…”

An Overview on the Spinning Triangle Based Modifications of Ring Frame to Reduce the Staple Yarn Hairiness

“…The compact-Siro spun yarn incorporated the advantages of compact and Siro yarns [40]. It is conducted on a compact ring frame by simultaneously feeding two rovings, and incorporates the features of both Compact and Siro-spinning systems.…”

“…It also works well with other animal fibers, including cashmere and other fibers with long staples. Yuzheng and Yang claimed that siro-spinning yarns are stronger than those spun with a conventional spinning process [24]. Mezarcöz et al investigated that compact-siro spinning can improve energy distribution in yarns, making them more elastic and fast-growing.…”
