“…Da mesma maneira, as fibras naturais de origem vegetal têm tido lugar de destaque quanto a sua utilização em agroindústrias e até mesmo na indústria automotiva, devido à alta disponibilidade de matériaprima provinda de recursos renováveis (SILVA et al, 2009) e a fatores, como: baixo custo, boa resistência térmica e mecânica, baixa densidade, e biodegradabilidade (FURLAN et al, 2012).…”

O objetivo do artigo foi conceituar termos utilizados na literatura acerca das teorias propostas em práticas conservacionistas e preservacionistas da biodiversidade, e elencar alternativas substitutas às atividades extrativistas intensivas que geram externalidades negativas a população, como as práticas de coleta do Xaxim, Piaçava e Sisal. As estratégias conceituadas buscam um encontro com as necessidades da população frente aos aspectos ambientais, sociais e econômicos, no entanto, ainda se mostram distantes da correlação harmoniosa.

“…However for fashion or design applications generally high values of resistance parameters are not necessary as in the case of engineering applications, being more relevant the aesthetic appearance. Withal, the main limitation about incorporation of natural fibers in polymeric materials is relative to the loss of mechanical resistance, many times due to the weak interaction between the polymer and the fiber (Furlan et al 2012), since the lack of cohesion influences directly the intermaterial tensions. In some cases, composites could have the tendency of forming voids and cracks in the interior and on the surface of its components (Almeida and Rezende 2001).…”

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.
