“…As the draw ratio increases during yarn preparation, the soft segments undergo stretching. When the draw ratio reaches an extremely high level, as observed with 4.6 in the present case, the elastane surpasses its yield stress threshold, rendering the elastane more susceptible to rupturing (Rahim et al, 2023).…”

“…Parameters such as spinning draft (between the pair of back and front drafting rollers) and elastane draw ratio (between elastane feed roller and V-grooved guide roller) were adjusted in such a manner that yarn count remains the same with different elastane proportions. The consumption of elastane and jute in core-spun yarns was calculated according to the following formula (Rahim et al, 2023) that are mentioned in Table 4.…”

“…8 that the breaking stress (tenacity) of all jute/elastane core-spun yarns is lower than the 100% jute yarn. It is a usual phenomenon of core-spun yarn that its strength decreases after inclusion of elastic core lament into spunyarn (Rahim et al, 2023). Lack of jute-elastane and inter-jute cohesion can be ascribed to the lower strength of core-spun yarns than 100% jute yarn.…”

Stretch-denim is a unique, trendy, and sturdy fabric produced with coarser cotton yarns requiring high consumption of cotton fiber. With the increasing expenses of cotton and the adverse ecological effects linked to its cultivation, it became necessary to investigate an alternative fiber. Jute, despite being a low-cost, biodegradable and sustainable natural cellulosic fiber, is often underappreciated in the textile industry primarily because of its inherent stiffness and poor aesthetics. Herein, a groundbreaking jute/elastane core-spun yarn was produced, for the very first time, to develop fabrics like denim with comfortable stretch. To accurately predict the elastane draw ratio, an I-optimal design, which is a part of the response surface methodology, was employed using design expert software. The study involved nine experimental runs to produce 276 tex core-spun yarns at different elastane draw ratios ranging from 1.4 to 4.6. Surface response models were developed and found statistically significant for mass variation, imperfection, hairiness, tenacity, and elongation of yarn, with p-values below 0.05. Using the optimized formulation obtained from the response models, the optimum elastane draw ratio was determined to be 3.42, which was then used to produce optimized core-spun yarn. The quality parameters of produced yarn closely matched the predicted values, suggesting the effectiveness of the response model in navigating and predicting the characteristics of jute core-spun yarn. The newly developed elastic jute yarn is expected to widen the applications of cellulosic jute yarns where elasticity is necessary, especially in stretch-textile like denim products by replacing the cotton counterpart.

“…Essentially, spun yarns consist of twisted staple fibers, wherein hairy or projecting fibers contribute to a soft and fuzzy texture on the yarn surface (Rahim et al, 2023). Maintaining an optimal level of hairiness in yarn is beneficial as it improves the comfort of the fabric.…”
The worldwide manufacturing industries are actively adopting greener and eco-friendly production approaches, aligning with the Sustainable Development Goals (SDGs) and particularly focusing on Goal 12. This objective strives for responsible material management, with a strong emphasis on significantly decreasing waste generation through preventive measures, recycling, and reusing resources. This research introduces a sustainable method for manufacturing Siro grindle yarn, which involves maximizing the utilization of recycled cotton fibers sourced from pre-consumer fabric waste. The process involved the preparation of two rovings, one colored (red) and the other white, incorporating varying percentages of recycled cotton fibers along with virgin cotton. To achieve a vibrant grindle effect in the yarn, a newly designed 2-ply compact-Siro spinning technique was employed. This technique involves separately compacting two drafted fiber strands before uniting them through twisting. As a point of comparison, Siro grindle yarn was also manufactured in a conventional ring frame. Through skillful engineering, grindle yarns with a count of 20 Ne containing up to 50% recycled fiber were successfully manufactured. The yarns produced using the compact-Siro spinning technique exhibited notable enhancements in both structure (reduced hairiness, unevenness, and imperfections) and properties (increased strength and elongation). These grindle yarns demonstrated suitability for producing knit fabrics with aesthetics comparable to commercial grindle fabrics made entirely with virgin fibers.
“…Elastic core-spun yarns have revolutionized the textile industry due to their versatile applications. They are manufactured by wrapping an elastomeric core filament with a sheath of staple fibers, mostly cotton, combining the stretch and recovery properties of the core material with the desired aesthetics of the outer sheath [ 1 , 2 ]. These yarns exact the consumer expectation of garments that offer pleasant body movement while retaining their form-fitting ability even after repeated use [ 3 ].…”
