a notable difference in various aspects. Leather production typically involves animal hides, which can vary in price depending on the animal source and quality, ranging from $2 to $10 per square foot. On the other hand, the raw materials for wool/rubber composite, including wool fibres and natural rubber, are cost-effective. The estimated cost of the coarse wool/natural rubber latex composite, wool/latex/PU embossed composite and heat transfer printed coarse wool/ natural rubber latex composite is $2.5-3.0, $3.5-4.0 and $5.0-5.5 per square foot, respectively. However, the final product cost can vary depending on factors such as quality and design, ultimately influencing consumer preferences and market demand. And while the novel wool-natural rubber composite imitates leather in many aspects, it does not in all. Thus, it could be an alternative commercial solution for a few applications such as bags and wallets, whereas for shoes or sandals it may not be a perfect material. As well as having a potentially lower carbon footprint than traditional leather production, thanks to utilising renewable resources, the substitution of coarse wool for leather has a significant socioeconomic effect. Coarse wool is sometimes considered a low-value by-product, yet using it as a leather substitute can create new markets for wool, reducing waste and boosting sheep farmers’ profits as well as supporting local economies. In conclusion, the development of artificial leather made from renewable and biodegradable wool composite with various techniques presents a promising innovation for both the current and future fashion market. These wool-based materials offer a sustainable alternative to traditional leather, addressing concerns about environmental impact and animal welfare. The usage of non-renewable resources as well as plastic pollution can be decreased by

switching to wool composites from synthetic materials. By combining wool with innovative manufacturing techniques and reinforcement, designers can create versatile, durable and stylish products that appeal to eco-conscious consumers. Additionally, the use of wool composites provides opportunities for creativity and differentiation in fashion design, catering to
