Abstract
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.
Highlights
In Brazil large amounts of textile clothing are being discarded along with scraps and textile virgin residues originated by apparel confection industries
The present study aimed the production of new composite materials and the analysis of their tensile and aesthetical characteristics in order to collaborate for the product eco-design methodology based on the recycling of textile wastes, which are extremely abundant in Brazil
The present study showed an alternative for textile recycling by means of production of thermoset composites made from thermoset resins reinforced with recycled cotton textile residues, on which tensile tests were carried out
Summary
In Brazil large amounts of textile clothing (often in good conditions) are being discarded along with scraps and textile virgin residues originated by apparel confection industries. According to a survey by MDIC - Brazilian Ministry of Development, Industry and External Trade, and ABIT Brazilian Association of Textile and Apparel Industry (2011), carried out in 2010, television was pointed as the major medium of fashion dissemination by 72% of respondents. There are large amounts of scraps and textile residues originated by apparel confection industries. In Brazil, there are many regions with intense confection activity, mainly in the states of São Paulo, Santa Catarina and some parts of the Northeast region of the country. According SINDITEXTIL - Union of Spinning and Weaving Industries of the State of São Paulo – Brazil (2012), Brazil produces 175,000 ton of residues from the textile industry per year. In São Paulo city (São Paulo state, Brazil), approximately 10 ton per day (in the neighborhood of Brás) and 16 ton per day (in the neighborhood of Bom Retiro) of textile residues are produced and usually this waste ends up in landfills (Vianna 2011)
