Utilization of Cotton Spinning Mill Wastes in Yarn Production

Abstract

Efficient use of natural resources and utilization of recoverable wastes are getting more and more important day by day since recovering wastes have both economic and environmental benefits. As the source material costs constitute the majority of the yarn production costs, decreasing raw material costs provide considerable advantages for spinners. From the point of textile manufacturing, various production wastes can be reused in textile industry. In each step, from ginning (for cotton fibers) to end product formation, recyclable/recoverable waste materials are generated. However, mainly polyester products are recycled (r-PET) and used again in textile industry by 100% or in blends with other man-made or natural fibers. Compared to research on r-PET, recovered cotton fibers inspired interest recently. The main objective of this study is to fill the gap in the literature via investigating the properties of the yarns produced with recovered cotton wastes, generated in different sources. For this purpose, spinning mill waste types were selected. In this experimental study, different waste types (card waste, blowroom waste, and fabric waste) and blending ratios were used. As a conclusion, the effect of waste type and blend ratio on the physical and mechanical properties of the yarns and the fabrics, produced with virgin and waste cotton fibers, were analyzed.

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

“…Considering ecological and economic aspects, companies are required to launch new technologies that can process various fibers with lower quality than virgin fiber sources or can adapt to different processed fibers and settings suitable for various fibers. 1 Textile waste has two main categories: production and post-production waste. 1,2 Production waste is formed during each production stage (from fiber to yarn, from yarn to fabric and cloth, or technical fabric processing).…”

İplik Atıklarından Kapalı Döngü Geri Dönüşüm İplik Üretimi ve Fiziksel Özelliklerinin Sürdürülebilirlik Kapsamında Araştırılması

“…As the proportion of waste fibers increased, the air permeability of the fabrics decreased depending on the yarn hairiness. For pilling values, the highest results were obtained for fabrics with card waste with the highest short fiber content [28].…”

Preparation of Microcrystalline Cellulose from Cotton Yarn Spinning Mills Wastes: Effect of Pretreatment and Hydrolysis Reaction Condition on the Product Characteristics

“…Cotton fiber is still a famous textile material for clothing in tropical regions such as Indonesia. Along with the increasing demand of clothing textile from cotton, the cotton yarn spinning industry was still left out up to 11% of its raw material as wastes in the form of short cotton fibers [1]. Hence, some of them could not be recycled back to the spinning mills due to a down-graded fiber quality in term of fiber length, strength, micronaire, and uniformity.…”

“…Commonly, waste fibers generated in spinning mills can be returned to the same blend from which they came up. However, only up to 5% of wastes can be used in both carded ring-spun yarn and fine rotorspun yarn, 2.5% of wastes used for combed yarns, and about 10 and 20% of wastes used for medium and coarser rotor yarns, respectively [1]. A study of cotton fiber wastes recycling for both conventional ring-spun and open end-rotor yarn spinning found that blend yarns with pneumafil wastes resulted with better yarn qualities.…”
