Textile products are present in all aspects of our lives and drive a significant part of the world economy. Issues related to enterprise competitiveness, sustainability, limitation of natural resources, environmental and social impacts are increasingly considered. In this context, the recovery and recycling of textile materials are essential. This study aimed to present an overview of the Brazilian textile and clothing industry, highlighting the mechanical and chemical recycling processes and reuse. We also discuss the reasons for importing textile waste, and considerations about circular economy concepts, correlating them to the key factors and obstacles involving industrial operation of textile recycling. The authors conducted technical visits to textile recycling industries in order to observe the production processes and identify their main challenges. Nevertheless, the initiatives show that Brazil is on track for industrial sustainability, following a global production trend.
The recycling of textiles is an issue that requires immediate attention in order to address the management of textiles derived from household waste, as well as scraps generated throughout manufacturing textile processes. The present study aimed to produce composites employing three different types of thermoset resins (epoxy, polyester orthophthalic and polyurethane) reinforced with recycled cotton textile residues on which tensile tests were carried out. The incorporation of 30% (v/v) of textile reinforcement in composites made from the specific epoxy resin employed in the present study showed an increase of approximately 2-fold relative to pure resin tenacity and Young's modulus (respectively from 0.09 to 0.16 MPa and from 0.5 to 1.2 MPa). For composites made of orthophthalic polyester resin, an increase was observed of 2-fold relative to pure resin tenacity and 3-fold relative to Young's modulus (respectively from 6.5 to 13.8 MPa and from 193 to 772 MPa). No significant alterations were observed for these parameters in polyurethane resin composites (16 MPa for tenacity and near 700 MPa for Young's modulus) probably because the modulus value supplied by the fraction of cotton fiber is not as significant as that one from the pure polyurethane resin. Two propositions of fashion accessories were made by employing these composite materials. Also, the artworks of renowned Brazilian designers, namely, Campana Brothers and R. Sobral, were analyzed to develop the artwork of such accessories for the present "documentation process". Thus in the present study aesthetic and technical aspects are analyzed together covering all production phases of material, processes, creation and design of final product.
O Brasil se configura como um dos maiores produtores mundiais do setor têxtil e vestuário. É um importante produtor da fibra de algodão, de fios, de tecidos planos e de malha, além de estimular o PIB do País gerando milhões de empregos diretos e indiretos no referido setor. Contudo, tal atividade cria diversos problemas ambientais como, por exemplo, a geração de resíduos sólidos oriundos dos processos industriais, confeccionistas e também do pós-consumo. O presente estudo visou apresentar o panorama atual dessa problemática e apontar possibilidades de reciclagem têxtil. Como metodologia, foram analisadas literatura científica, patentes, legislação e outras fontes bibliográficas, bem como foram consultadas informações de diferentes órgãos e instituições relacionadas ao setor têxtil, confeccionista e meio ambiente. Além disso, foram analisadas manualmente amostras de resíduos têxteis cedidas por uma indústria recicladora a fim de constatar algumas problemáticas referentes ao processamento desse material. Assim, apresenta-se um panorama sobre a reciclagem têxtil no Brasil, relacionando as principais problemáticas ligadas a essa atividade, ainda não muito estimulada em nível nacional.
