“…The shapes of the spinning triangle continue to change with a varying period ranging from 0.05 to 0.5 s, which is observed based on videos shot by a high-speed camera. This phenomenon resembles Solospun yarns, 8 in which the spinning triangle is split into three to four substrands by the split roller and fiber strand splitting is actively controlled by the split roller groove with the fixed period of 0.1–0.2 s. Obviously, the strand spacing and twist multiplier have a great influence on the three-strand spinning triangle geometry, which will affect the yarn properties. The relationship among the strand spacing, twist multiplier, and yarn properties will be systematically investigated in this work.…”

“…1,2 Yet, it still dominates the market due to its flexibility in terms of raw material and yarn count. 3,4 In recent years, many alternative spinning technologies have been developed to meet the demand for yarns with better properties or to improve production efficiencies, such as compact spinning, 5,6 Nu-Torque, 7,8 Siro spinning, 9 Solo spinning, 10 embeddable and locatable spinning, 11 jet-ring spinning, 12 ring spinning with a diagonal path, 13 contact surface spinning, 14,15 agent-aided spinning, 16 and so on.…”

Spinning is one of the major steps in textiles to convert staple fibers from either natural or synthetic sources into continuous and twisted yarns, and ring spinning has always been the dominant yarn technology since its invention. Recently, many ring-based modifications have been developed to improve yarn productivity and properties. In this work, a modified ring spinning technique has been developed by feeding three-roving strands into a conventional ring frame for producing yarns with better performance. A strand delivery guide with different spacings (1–5 mm) was used for the production of three-strand yarns. The quantitative relationships between the spinning parameters and yarn properties have been systematically investigated. The properties of the modified yarns were evaluated, including yarn tensile properties, evenness, and hairiness, and the statistical relationships were obtained by least squares polynomial fitting. The experimental results indicate that the guide spacing and twist multiplier significantly influence the yarn properties. The spinning triangle of the modified yarns resembles Solospun yarns, suggesting supreme yarn abrasion performance.

“…A weft insertion mechanism via magnetic actuation can also save 60% of energy 35 . Eliminating processing steps is another noticeable development in textile conversion [36][37][38] . Another example is the combination of spinning and knitting pro-cesses in a single machine that allows the direct input of fibre slivers or roving into a circular knitting machine, thus eliminating ring spinning and yarn storage and saving energy, space and operational costs; reducing CO2 emissions; and improving product quality 39 .…”

Throughout their life cycle, textiles produce 5-10% of global greenhouse gas emissions and consume the second-largest amount of the world's water with polluting microplastics and chemical agents released to waterways. Here we examine the state-of-the-art technology developments meant to solve these problems in a cradle-to-grave fashion. We analyse their impacts with respect to the Sustainable Development Goals in the United Nations Agenda 2030, particularly those concerning the deployment of natural resources, energy and environmental impacts. We follow a systematic analytical framework that identifies and elucidates impactful technologies. We further discuss future directions along which the green transformation of textiles could be accelerated.Textile products have a global market valued at US$961.5 billion, with major sectors in apparel (~75%), technical textiles (~12%) and household goods (~9%) 1 . Approximately 90 billion articles of clothing, or 62 Mt, are manufactured and sold each year 2 . Apart from meeting essential clothing needs, the textile supplier chain provides ample employment opportunities, fuels economic and social developments, and improves well-being and life quality, especially in developing countries.The life cycle of textile and apparel products involves different stages and players because the product supply chain is long, highly branched and globalized, as shown in Fig. 1. The life cycle begins with making or harvesting raw materials for textile fibres, originating from plants, animals and petroleum, among other sources, thus involving the agriculture and chemical industries. Fibre production routes vary greatly, from harvesting from plants or animals to fibre forming through methods such as melt spinning, dry spinning and wet spinning. At the textile conversion stage, fibres or fibre blends are used to make yarns and fabrics with the desired tenacity, durability, colour, pattern and hand feel. Products such as garments require further processing to realize the final forms to be used by consumers. The distribution stage involves logistics, wholesalers and retailers. Product cleaning and care are normally conducted at home as laundry at the usage stage. The disposal stage has several branches; the used products may be sent to landfills or incinerators or alternatively recycled or reused. Since the suppliers of This is the Pre-Published Version.

“…Furthermore, its operational simplicity and amenable controllability contribute to its prominence 3 . So far, four main ring spinning machines have been developed to process four types of natural fibers, namely cotton, wool, linen, and spun silk, and other natural or synthetic fibers are processed using the appropriate machine depending on fiber length and the final purpose [4][5][6] . But the important note is that the fundamental principles of all of them are the same.…”

Most textile products incorporate yarn as a fundamental element in the production process. Among various yarn manufacturing methods, the ring spinning system stands out as a crucially employed technology due to its advantages including yarn quality, evenness, low hairiness, and ease of handling. The parameters of drafting zone in this technology have a great impact on the quality of yarns. Typically, tuning this drafting zone parameters is time-consuming and costly through trial and error method. This study introduces an algorithmic procedure based on response surface methodology (RSM), experimental modeling, and multi-objective optimization to reduce unevenness percentage (U%) and imperfection index (IPI). Input parameters, including cots hardness of front and back top rollers, spacer size, and break draft, are optimized. Results indicate superior prediction performance of the artificial neural network (ANN) (average vaule of TGF = 1.9996) compared to RSM (average value of TGF = 1.8668). Consequently, ANN is selected for optimization. Furthermore, coupling the genetic algorithm with two ANN-based models reduced IPI from 39 to 33.67 and a reduction from 9.73–9.67% occurred in terms of U%. The final setting of Input parameters were cots hardness of front roller of 70 shore and cots hardness of back roller of 76 shore, spacer size 2.8 mm, and break draft of 1.26. This method efficiently optimizes the drafting zone parameter, enhancing yarn quality.
