Abstract

This work aimed to fulfil one of the great consumer trends related to ethically and environmentally sustainable attitudes. The main concept was to develop an alternative material to natural and synthetic leather by creating new bio-coated textile structures with improved environmental credentials, and to use vegetable wastes and by-products from agroforestry industries, as well as biopolymers. Different residues, such as sawdust and pine bark were successfully incorporated in polymeric aqueous formulations and applied as textile coatings. The Life Cycle Assessment of these new textile products showed that they present a lower environmental impact in comparison to natural leather used for clothing and shoe applications. Overall, the alternative material developed here is a favourable sustainable material. The use of by-products to create bio-based materials comprises a great potential for a broad spectrum of applications in other fields in the Textile and Clothing Industry such as fashion, eco-design, sports and protection apparel, furniture decoration, home textiles, footwear, fashion accessories, in addition to others.
