Abstract:

The aim of this paper is to present the utilisation of a Solospun roller in the Sirospun spinning system in order to improve the properties of worsted wool/polyester yarns, especially the yarn hairiness. In this work, a Solospun roller was used and different worsted yarns (45% wool, 55% polyester) with a yarn linear density (count) of 50 tex and twist factors (áTt) of 2530, 2846, 3162, 3478, and 3795 were produced using the Sirospun spinning system with and without a Solo-spun roller. Afterwards, the yarn physical properties including hairiness, tensile strength, elongation, unevenness and abrasion resistance were measured and compared. The results indicate that increasing the yarn twist factor within the range of 2530 to 3478 decreases the hairiness of Solo-Siro spun yarn. It is also shown that the hairiness of Solo-Siro spun yarns is significantly less than that of Sirospun yarns. The evenness, count and twist of Solo-Siro spun yarns change slightly in comparison with Sirospun yarns. However, other yarn specifications, such as tensile strength, elongation and abrasion resistance remain almost un-changed.
