Uso de corantes de origem natural para o tingimento de artigos têxteis de moda

Abstract

Faced with the chaos, especially environmental and social, that the planet earth has experienced, much has been said in sustainability and their corresponding strategies to try to stop this situation. Going to meet this initiative is the present work, entitled "Use of natural dyes in textile dyeing Fashion" whose main objective is to bring natural pigmentations without such aggressive formulations for use in articles of clothing industry, thus try to contain, at least in part, the damage to the textile industry, a major environmental pollutant, has caused in the world. For this, a methodology was established which consisted of four steps, i.e., search of bibliographic data for reference on the subject in question and obtaining natural pigments from Amazonian plants, choice of textile substrates selected according to the affinity with dye extracts, analysis of potential application of dyes on the substrates studied (check the index of dye fastness to washing and light) and production of a color palette, a collection and garments with dyed fabrics with some of the dyes studied. The main results of this work were obtained dyes that, in interaction with the fibers, caused uniforms dyes, little amount of these materials used, chemical composition inserted in sustainable patterns, little waste expelled the remains of dye baths, a varied color palette, good fastness to washing and light, clothing collection and four pieces made, with the use of natural dyes, which gave the dye extracts sustainable quality.

The natural dyes extracted in São João de Côrtes, Alcântara, Maranhão: an approach oriented to sustainable design

“…According to Rodrigues (2013), the designer committed to sustainability considers the whole life cycle of a product, i.e. what happens during the extraction of the raw material, the stages of production and use, and how its discard is done.…”

“…This information can be on labels and packaging, for example. The previous reflections extend possibilities for the work of the designer, who can intervene in the clarifications between scientific and popular knowledge, as well as awaken the interest of the communities to act according to the demands of a consumer market eager to get in touch with differentiated products with sustainable qualities, as can be seen in the growing study on the feasibility of using natural dyes on fabrics in the fashion textile industry (RODRIGUES, 2013). In the case of São João de Côrtes, investments in the obtainment of knowledge can turn the attention of the community to a possible alternative form of income, returning to a traditional activity, directing the concentration in the purpose of addressing the issues of revaluation of knowledge about the production of natural dyes by the villagers, directing the look at identities, as well as to verify the solidity of these products, the quantities of materials for dyeing and the construction of a color chart.…”
