Design of an environmentally friendly leather-like fabric based on thermoplastic polyurethane covered yarn

Abstract

By means of knitting and weaving, the new yarn was woven into a new eco-friendly leatherette. A series of research methods and data are summarized through the optimization and improvement of the design process and the heat-setting treatment of the fabric after weaving, which will bring a breakthrough in the reform of the preparation, research and development of new environmentally-friendly materials and product application. The new environmentally-friendly imitation leather fabrics is superior to similar products and boasts advantages in product application, such fabric is comfortable, breathable, waterproof, windproof, folding-resistant, wear-resisting and biodegradable. The cost of its production is much lower than expensive leather products, in the meantime, the space for design and development in the aspect of fabric texture, pattern, and color can be expanded more compared with other leather and imitation leather products.

Examination of the influence of hydrothermal treatment of textile materials on their physical and mechanical properties and development of innovative technology

“…In case of sudden narrowing, equation ( 6) is used to calculate the pressure loss, which requires the determination of the coefficients ζ and ε (local resistance and compression). The formula (3) is used to determine the coefficient ε, where n = F 2 /F 1 -the ratio between the areas of holes in a narrow section and a wide section (23)(24)(25):…”

“…K. Pandey et al [23] noted that the use of new methods of processing textile materials may require additional attention to the technological aspects and control of the hydrothermal treatment process. This means the need to train personnel and create more complex systems to ensure the stability and reliability of the production process.…”

Growing mycelium leather: a paste substrate approach with post-treatments

“…This may be a single layer or multiple layers introduced at intervals, allowing the hyphae to grow in between the woven fibers, fusing the layers within the structure of the material. Alternatively, a textile layer can be applied after the material has been treated using an adhesive (Wang et al 2022).…”

Polymeric Biocomposite Based on Thermoplastic Polyurethane (TPU) and Protein and Elastomeric Waste Mixture

“…TPU can also meet current requirements such as anti-static properties, increased resistance to abrasion, flexibility at low temperatures and anti-microbial activity, and the most important property is the one relating to comfort. These properties can be improved by using compatibilizing agents (polyethylene-graft-maleic anhydride-PE-g-MA) and reinforcement agents (with natural fibres modified with polydimethylsiloxane) [26,27]. PE-g-MA improves the properties of polymeric biocomposites such as tensile strength, tear strength, resistance to chemical agents, etc.…”
