Summary
This summary is machine-generated.This study explores using recycled cotton in dual-core elastic yarns for denim. Results show recycled yarns have lower strength but higher imperfections, with T400 yarn identified as the best sustainable option.
Area Of Science
- Textile Engineering
- Sustainable Materials Science
- Circular Economy in Textiles
Background
- Growing environmental concerns drive the textile industry towards sustainable manufacturing.
- Pre-consumer knitted fabric waste offers a viable source for recycled cotton fiber.
- Developing dual-core elastic yarns from recycled cotton can reduce environmental impact.
Purpose Of The Study
- To investigate the production and properties of dual-core elastic yarns using recycled cotton fibers.
- To compare the performance of yarns made with different elastomeric components and recycled cotton.
- To identify the optimal yarn composition for sustainable denim production using decision-making tools.
Main Methods
- Redesigned ring spinning method to produce dual-core yarns (Ne 18/1) with various elastomeric cores (T400, PBT, PES, Lycra) and recycled/virgin cotton.
- Characterization of yarn properties: strength, imperfection index (IPI), elongation, unevenness, and hairiness.
- Statistical analysis using One-way ANOVA and multi-objective optimization based on ratio analysis (MOORA) for yarn selection.
Main Results
- Yarns produced with recycled cotton exhibited lower elongation and strength compared to virgin cotton yarns.
- Higher values for imperfection index (IPI), unevenness, and hairiness were observed in recycled cotton yarns.
- One-way ANOVA confirmed significant variations in all tested yarn characteristics based on core material.
- The MOORA technique identified T400 filament-containing yarn as the superior option among PES, PBT, and T400 alternatives.
Conclusions
- Utilizing recycled cotton in dual-core elastic yarns presents a sustainable approach for the textile industry.
- While recycled yarns show some performance trade-offs, optimization is possible.
- Decision-making tools like MOORA are effective for selecting the best-performing sustainable yarn options.

The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...
As the construction industry moves towards more eco-friendly practices, concrete's adaptability and its ability to incorporate sustainable features make it a key material in the drive towards greener building solutions.
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground...
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...
