Abstract(s)
A Indústria Têxtil e Vestuário (ITV) é um dos setores mais importantes da economia
portuguesa. Contudo, para o sucesso da ITV, é necessário que as empresas que operam
neste setor apresentem produtos de qualidade e de acordo com as exigências de cada
cliente, sendo constante a necessidade de inovação. A realização do estágio curricular
numa empresa do setor têxtil, FITECOM – Comercialização Industrialização Têxtil, SA,
permitiu um maior conhecimento sobre esta indústria e de todos os processos a ela
associados, em especial do processo de desenvolvimento da cor – tinturaria.
Considerada uma arte e uma ciência, a origem da Tinturaria é difícil de precisar ao
certo. A descoberta do primeiro corante sintético, a mauveína, no ano de 1856 por Perkin,
ditou o início de uma grande evolução nas técnicas de tingimento que até então eram
bastante rudimentares. O desenvolvimento de novos corantes e fibras levaram a um
estudo cada vez mais profundo dos processos de tingimento, sempre com o objetivo de
diminuir os custos e riscos ecológicos, assim como aumentar a solidez dos tingimentos.
Desta forma, estão apresentados os vários procedimentos realizados ao longo do
estágio, tanto no laboratório de tinturaria como no laboratório de controlo de qualidade,
sendo abordados também mais ao pormenor os testes de solidez dos tintos.
A necessidade da utilização de produtos e certificações sustentáveis na indústria
têxtil é imperativa mediante os desafios ambientais, pois a indústria têxtil ainda é
conhecida pelo seu impacto significativo no meio ambiente, devido ao consumo intensivo
de recursos naturais, emissões de poluentes e produção de resíduos. A incorporação de
produtos sustentáveis e de certificações adequadas são medidas essenciais para mitigar
esse impacto negativo. Desta forma, foi desenvolvido, na empresa, um procedimento
com recurso a corantes naturais no processo de tingimento.
The Textile and Clothing Industry (TCI) is one of the most important sectors of the Portuguese economy. However, for TCI to be successful, it is necessary that companies operating in this sector present quality products in accordance with the requirements of each client, with the need for innovation being constant. In this context, completing an internship at a textile sector company, FITECOM – Comercialização Industrialização Têxtil, SA, provided a deeper understanding of this industry and all the processes associated with it, particularly the color development process – dyeing. Considered an art and a science, the exact origin of dyeing is difficult to pinpoint. The discovery of the first synthetic dye, mauveine, in 1856 by Perkin, marked the beginning of a significant evolution in dyeing techniques, which were quite rudimentary until then. The development of new dyes and fibers led to an increasingly in-depth study of dyeing processes, always with the goal of reducing costs and ecological risks, as well as enhancing the colorfastness of dyes. This summary outlines the various procedures carried out during the internship, both in the dyeing laboratory and the quality control laboratory, with a more detailed focus on colorfastness tests. The imperative need for the use of sustainable products and certifications in the textile industry is emphasized in light of environmental challenges, as the textile industry is still known for its significant impact on the environment, due to the intensive consumption of natural resources, pollutant emissions and waste production. The incorporation of sustainable products and appropriate certifications are essential measures to mitigate this negative impact. In this way, a procedure was developed in the company using natural dyes in the dyeing process.
