“…Having in mind that both fabrics were knitted on the same knitting machine using the same cotton yarn, the differences between their structural parameters are attributed to the different contents of elastane (8% vs 4%) and its fineness (235 dtex vs 78 dtex). According to Gun and Kuyucak, 23 elastic fibers are commonly used to enhance fabric thickness, weight, and density, that is, fabric compactness, which is also the case in the current investigation. Namely, as a consequence of the introduction of higher content of less finner elastane, that is, the greater stretching of the introduced elastane, yarn curvature increases in the third dimension and causes an increase in the fabric CoEL235R thickness, 24 the loops become closer and the fabric stitch density increased altogether resulting in higher fabric weight.…”

This research studied the influence of common wet processes (i.e. bleaching, dyeing, or softening) on the quality of 1 × 1 rib cotton/elastane knitted fabrics. The changes in their structural (thickness, weight, and stitch density) parameters, mechanical (bursting elongation and stiffness), comfort (air permeability and moisture sorption), and esthetic (pilling propensity) properties are discussed as an influence of the used elastane type (multifilament or monofilament), and content (4% or 8%), and applied wet processes. The severity of the bleaching process (high pH value and boiling temperature) and the resulting fabrics’ less compact structure contributed to a 17.3% higher bursting elongation of bleached compared to the dyed fabrics. Fabrics having a higher content of less finner elastane (8%, 235 dtex) have 40% and up to 21% higher stiffness and bursting elongation than fabrics containing 4% elastane of 78 dtex. The aforementioned fabrics (having 4% elastane) are softer and more comfortable since they are characterized by up to 37.9% and 5.6% higher air permeability and moisture sorption than fabrics having 8% elastane. Dyed knitted fabrics provided a better intensity of warm/cool feeling than the bleached ones due to the better comfort properties. Up to 5000 pilling cycles, the fabrics’ pilling propensity increased with an increase in elastane fineness, while at the same number of pilling cycles, dyed fabrics have a lower pilling propensity than the bleached ones. The calculated complex criterion of fabrics’ quality revealed that pilling propensity and stiffness are the main contributors to their quality that ranged from excellent to satisfying. The “satisfying” fabric quality was improved to “good” by softening with silicone softener, whereby the high content of silicon (197.51 μg/g, assessed by ICP-OES) within the bleached fabric having 8% elastane contributed to lower piling propensity compared to the corresponding non-softened fabric.

“…After the same pilling cycles, CoB has the same or a lower pilling grade as Co2ELB, which is due to its higher compactness (Table 2) and bursting elongation (Table 1). Elastane in fabric Co2ELB prevented the migration of fibers from its inside to the surface (Gun and Kuyucak 2021). Similarly, Sitotaw and Gedion (2020) indicated that the single jersey cotton/elastane fabric has higher pilling resistance compared to 100% cotton fabric, while Haji (2013) reported increased pilling resistance with an increase of lycra ratio in the cotton-based single jersey fabrics.…”

“…The fabric pilling observed during garments' daily wearing or washing represents one of the essential factors contributing to its quality (Gun and Kuyucak 2021). Therefore, the formation of pills over the fabric surfaces was evaluated as a grade from 5 (no pilling) to 1 (dense surface fuzzing and/or severe pilling).…”

The quality of cotton and cotton/elastane single jersey knitted fabrics before and after softening was evaluated through their mechanical properties, pilling, and volume electrical resistivity. Elastane-containing fabrics have higher bursting elongation and stiffness, lower bursting strength, the same or higher pilling grade, and 23-27% lower electrical resistivities compared to 100% cotton due to the increased compactness that enables better contact between the loops, and easier flow of charge through them. Softening does not affect or slightly improves the fabric pilling (up to 1000 cycles); it decreases fabrics' stiffness and increases their bursting strength and electrical resistivities. The last one was significantly decreased after the in situ synthesis of Cu-based nanoparticles on fabrics' surfaces. Namely, fabrics were first treated with sodium alginate whose carboxylate groups crosslinked Cu 2+ -ions (from CuSO 4 solution) that were further reduced with ascorbic acid. In situ synthesis of Cu-based nanoparticles (detected by FESEM) improves the fabrics' quality and enables obtaining multifunctional fabrics having 3.4-9.6 times lower resistivities, which are in line with the content of Cu after reduction (determined using ICP-OES), up to 2.5 times higher antioxidant activity and provided maximum microbial reduction for E. Coli, S. aureus, and C. albicans.

“…The experimental and statistical findings show that all the performance characteristics of the fabrics are significantly influenced by the fibre type and the elastic properties of the yarn. Comparative research is done on the performance characteristics of plain knitted fabrics manufactured from open-end recycled and virgin acrylic yarns, as well as the effects of additional covered and PBT elastic yarns The abrasion results of the recycled acrylic fabrics with covered yarn and the PBT yarn do not statistically differ from one another [3].…”

One of the sectors of the global economy that releases the most pollutants is the textile industry. Textile waste can be divided into pre-consumer waste and post-consumer waste. During the cutting and manufacturing processes, factory pre-consumer waste is produced. Used clothing and other used textiles create post-consumer trash. Studies reveal that textile waste takes up almost 5% of total landfill space. About 84% of all waste is made up of clothing, and that waste is dumped in landfills where it takes up about 5% of the available space. Since only 10 to 25% of these end up as industrial waste, up to 95% of them can be recycled. The lifetime of clothing is thought to last three years on average. They are left on the land after that time. It is estimated one million metric tons of textiles are condemned annually. Instead of being recycled and reused, a lot of old clothes end up in landfills. This article focuses on different fabric wastes, their processing, the properties of recycled yarn, and the fabrics produced subsequently. There is a special focus on brands that have taken initiative to reduce textile waste by converting them into different products.
