Research on the Qualities of Cellulosic Yarn
Journal Title: Fibres and Textiles in Eastern Europe - Year 2018, Vol 26, Issue 1
Abstract
Cellulosic fibre is a kind of renewable fibre that has attracted more and more attention in textile processing recently. Yarn spinning is the first fundamental process in textile processing. Therefore, in this paper, taking viscose fibre and tencel fibre as examples, the qualities of cellulosic yarn were studied. Three kinds of pure viscose and tencel yarn: 14.6 tex (40S), 9.7 tex (60S) and 7.3 tex (80S), were spun on a ring spinning system modified with lattice apron compact spinning (LACS) and complete condensing spinning (CCS), respectively. The spun yarn qualities, yarn evenness, breaking strength and hairiness, were tested and comparatively analysed. Then two kinds of cellulosic blend yarn including 14.6 tex, 9.7 tex and 7.3 tex JC/R 60/40 yarn, and 14.6 tex, 9.7 tex and 7.3 tex JC/T 70/30 yarns were spun on a ring spinning system modified with CCS. The spun yarn evenness, breaking strength and hairiness were tested, and the cross sections of the spun yarns were presented using a Y172 Hardy’s thin cross-section sampling device. The results show that for both the pure viscose and tencel yarn, compared with LACS, CCS has better yarn evenness, a little lower yarn breaking strength and a little more hairiness, while the uniformity of yarn qualities are all improved. For the cellulosic blend yarn, compared with the pure cellulosic yarn, yarn evenness is worse, especially for the cotton and tencel blend yarn.<br/><br/>
