The relation between viscose fibers' characteristics and their yarn properties

Popis výsledku v původním jazyce

While cellulosic fibers have the third largest fiber’s market-share, the production of viscose (as regenerated cellulosic fibers) was growing globally during the first decade of the 21st century with an average annual rate of 7.7%. Most of these fibers are used for apparel industry and it is necessary to study the performance of these materials in textile yarns. This study reports the results for characterizing two sets of viscose yarns of the same linear density (25 Tex) that are produced at two different twist levels (409 and 877 twist/m). Viscose fibers characteristics including cross-section, fineness, orientation, and tenacity were evaluated and correlated to the produced yarns’ physical and mechanical properties. Yarn evenness, mass distribution, thin and thick places, yarn hairiness, as well as the tenacity were improved by increasing the twist multiplier for the same fibers. On the other hand, the productivity (kg/h) of these yarns were decreased for that increase in the twist multiplier. These results show the trade-off between the yarn quality and productivity, where increasing the twist to certain levels might enhance the product qualities, this will also decrease the productivity of the industrial process. Therefore, it is necessary to optimize these parameters according to the required performance and the end use of the produced yarns.
