Effects of waste cotton usage on properties of OE-rotor yarns and knitted fabrics

Abstract

The use of recycled materials has gained massive importance in textile sector as well as in other sectors as the effects of reduction of natural sources are felt all over the world. In this study, it was aimed to analyse the effects of recycled cotton usage on properties of OE-rotor spun yarns and knitted fabrics produced from these yarns. For this purpose, OE-rotor yarns were produced at different proportion levels of virgin cotton and waste cotton that derived from blowroom 25%, 50%, 75%, 100%, respectively. For better assessment, properties of OE-rotor yarns that contain waste cotton were compared with 100% virgin cotton OE rotor yarn. Physical, structural and mechanical properties such as unevenness, imperfections, hairiness, breaking force, elongation, yarn-to-yarn friction, yarn-to-metal friction and yarn-to-ceramic friction were measured by Uster Tester 4 SX, Uster Zweigle Hairiness Tester 5, Uster Tensorapid 3 and CTT by Lawson Hemphill. At the second part of the study, single-jersey knitted fabrics were produced from OE-rotor spun yarns. Effects of waste cotton proportion on knitted fabric properties such as pilling, abrasion resistance, bursting strength and air permeability were also evaluated. Results showed that, the use of up to 75% per cent of waste cotton blended yarns show no statistically significant differences on yarn and fabric properties.

The quality comparison of open-end rotor-spun yarns produced from cotton waste in gray state and after dyeing

“…3,4,21,22 The quality of production waste is better in comparison with post-production waste mainly in terms of fiber length and its variability. 18–22 Many authors 1–22 concentrate on the quality of fibrous material components at the beginning of the process by the standard parameters used for definition of cotton fibers. On the other hand, they do not indicate the quality of fibrous materials from the point of view of amount of neps, dust, and impurities amount.…”

“…Numerous studies have demonstrated how to optimally blend and reuse various production cotton waste, mainly carding stipes with addition of noils, and if necessary virgin cotton or polyester to get the high or regular quality of yarns has been demonstrated. 2,[6][7][8][9][10][11] The study on processing of cotton ginning waste into openend rotor yarn is presented in the literature 12,13 as is the processing of fully recycled fibers from fabric scraps. [14][15][16] The verification of suitable setting of the production line and selection of machine parts relevant for processing of cotton waste was also proven.…”

“…[14][15][16] The verification of suitable setting of the production line and selection of machine parts relevant for processing of cotton waste was also proven. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Published results represent the application of the first strategy when the cleaning efficiency of fibrous materials and best quality of semi-products in partial stages of the spinning process and the final yarn is expected.…”

“…Yarn and fabrics produced from 100% cotton gave the best results among all samples. The results of the study revealed that the use of recycled cotton in up to 75% of the mixture did not make a significant difference in the results [30].…”

“…Liu et al [13] studied the production of regenerated cellulosic fi bers from Co waste. Halimi et al [14][15], Hasani and Tabatabaei [16], Wanassi et al [17], and Kılıc et al [18] investigated the recycling of Co fi bers from waste Co yarns.…”
