Promising Effect of Processing Parameters on Yarn Properties in Rotor Spinning

The uses of recycled materials have gained massive importance in the textile sector and other application areas as the effects of reducing natural resources are felt worldwide. This study aimed to analyze the effects of recycled fiber usage on the properties of OE-rotor spun yarns and hand-woven fabrics produced from these yarns. For this purpose, OE-rotor yarns are produced at different proportion levels from virgin cotton and recycled fibers derived from knitted garment wastes at 25%, 50%, and 75%, respectively. For a better assessment, properties of OE-rotor yarns that contain recycled fibers and 100% virgin cotton OE-rotor yarns are compared. Physical, structural, and mechanical properties such as unevenness, imperfections, hairiness, breaking force, and elongation are analyzed by Uster Tester 5 SX, Uster Zweigle Hairiness Tester 5, and Uster Tensorapid 3. Plain and twill hand-woven fabrics are produced from OE-rotor spun yarns. Effects of recycled fiber proportion on hand-woven fabric properties such as pilling, abrasion resistance, and air permeability were also evaluated. Results showed that the use of up to 75% of recycled fiber cotton blended yarns shows no statistically significant differences in yarn and fabric properties.

“…For these reasons CV m % and IPI values of yarns are lower at lower main vacuum pressure. Hairiness is also comparatively lower at 6.0kPa because increased turbulence boosts the disengagement which consequences in adverse yarn hairiness properties [4]. The decrease in the number of fibers with leading and trailing hooks contributes to the improvement of yarn tenacity mainly [19].…”

“…Rotor spinning is the best process for utilizing the cotton waste that was obtained from carding, comber and ring spinning due to lower production cost, ample reduction in space and workforces and flexibility to automation. Now, it has been getting a stronger position in the field of spun yarn manufacture day by day [4][5][6][7][8]. Several investigations have clarified the matter that machine parameters affect the yarn properties ominously [9][10][11].…”

The qualities of rotor spun yarn greatly depend on the fibre properties as well as processing parameters especially when the yarn is manufactured from 100% waste cotton. The purpose of this work was to observe the effect of the main vacuum pressure of the transfer channel and the additional suction pressure for the trash removal on the quality of rotor yarn produced from 100% waste cotton. Mixing of spinning waste and virgin cotton is a common phenomenon in the case of producing rotor yarn but yarn manufactured from 100% waste cotton is a very rare case. Very limited study has been performed in this research field. For that reason, the experimental work was done in order to observe the influence of main vacuum and additional suction pressure on the quality of rotor yarn manufactured from waste cotton. Quality parameters such as mass variation (CV m %), imperfection index, tenacity, and elongation of six 10Ne rotor yarn samples were investigated by varying different main vacuum pressure as well as additional suction pressure. The results revealed that 6kPa main vacuum pressure and 0.5kPa additional suction pressure were the ideal values considering the overall quality of yarn.

“…The results of several investigations have revealed that machine parameters significantly affect the physical and mechanical properties of yarn [15][16][17]. Rotor yarns are less irregular compared to the ring-spun yarn because of multiple doubling [18]. Douglas [19] noted that high-speed modem machinery has resulted in overall quality improvement of rotor yarn.…”

This study explores the impact of doubling and auto leveling in draw frame on the quality of rotor yarns. Virgin cotton of Ivory Coast (55%) and waste cotton (dropping-1: 25% and dropping-2: 20%) used as raw material. Rotor-spun yarns of 20 Ne were manufactured from the slivers produced from carding machine, breaker draw frame, and finisher draw frame without and with auto leveler. The quality parameters of slivers and rotor yarns such as Um%, CVm%, Imperfections (thick place, thin place, and neps), and count strength product (CSP) were tested and analyzed. The Um%, CVm% of different sliver gradually decreased due to the action of doubling and auto leveler. In yarns, Um%, CVm% showed a similar trend as slivers. Thick places, thin places and neps also exhibited the decreasing pattern with the increase of sliver doubling and the use of auto leveler. The quality of yarns improved with the increase of doubling and yarns produced from finisher draw frame sliver with auto leveler showed the best result. The reason can be attributed to the most evened out sliver with better fiber orientation due to the combined action of doubling and auto leveling.
