Abstract(s)
A Indústria Têxtil e do Vestuário (ITV) distingue-se por ser um setor de elevada
relevância na economia mundial. Ao longo das décadas, esta indústria tem evoluído
significativamente, impulsionada por inovações tecnológicas e mudanças nas tendências de
consumo. A realização do estágio curricular na empresa A Transformadora – Fábrica do
Pisão Novo, Lda, permitiu uma análise e compreensão mais aprofundada dos setores
abrangidos pela empresa, em particular sobre o funcionamento de um laboratório de
tinturaria e das tarefas associadas.
Ao longo do tempo, a tinturaria passou por uma notável evolução, sempre aliada à
ciência, tecnologia e exigências do mercado. O marco que revolucionou a tinturaria foi a
síntese do primeiro corante sintético, que possibilitou, mais tarde, o desenvolvimento de
uma vasta gama de cores. A transição para os corantes sintéticos, assim como a criação de
novos substratos, através de fibras não naturais, permitindo o desenvolvimento de novas
técnicas de tingimento.
A sustentabilidade tornou-se uma prioridade na indústria têxtil, tendo em conta que
este setor é bastante conhecido pelo seu elevado consumo de água, produção de efluentes
poluentes e emissão de gases. Face a estes problemas e à crescente consciencialização sobre
o meio ambiente, estão a surgir inovações promissoras para reduzir o impacto do
tingimento, como processos de tingimento com pouca ou sem água. Os corantes naturais
também voltaram a ter destaque, à escala global, como alternativa sustentável aos
sintéticos.
O trabalho desenvolvido, ao longo de seis meses, teve como foco o desenvolvimento
de novas cores, melhoria na reprodutibilidade laboratório-produção, através da realização
de inúmeros ensaios de tingimento, com o objetivo de otimizar os processos tintoriais. Neste
período, foram realizados dois projetos experimentais. O primeiro incidiu na utilização de
água de rosas como corante natural, de modo a investigar as suas propriedades enquanto
corante e a sua aplicabilidade. O segundo envolveu a aplicação de corantes naturais, já
comercializados, com o objetivo de analisar os diversos comportamentos em diferentes
condições de tingimento.
The Textile and Clothing Industry (TCI) stands out as a sector of high significance in the global economy. Over the decades, this industry has evolved considerably, driven by technological innovations and changes in consumer trends. The completion of the curricular internship at A Transformadora – Fábrica do Pisão Novo, Lda, allowed for a deeper analysis and understanding of the sectors encompassed by the company, particularly regarding the operation of a dyeing laboratory and the associated tasks. Over time, dyeing has undergone remarkable evolution, always linked to science, technology, and market demands. The milestone that revolutionised dyeing was the synthesis of the first synthetic dye, which later enabled the development of a wide range of colours. The transition to synthetic dyes, as well as the creation of new substrates through non-natural fibres, allowed for the development of new dyeing techniques. Sustainability has become a priority in the textile industry, given that this sector is well known for its high-water consumption, production of polluting effluents, and emission of gases. In response to these issues and the growing environmental awareness, promising innovations are emerging to reduce the impact of dyeing, such as low or waterless dyeing processes. Natural dyes have also regained prominence globally as a sustainable alternative to synthetics. [2 linhas de intervalo] The work carried out over six months focused on the development of new colours and the improvement of laboratory-to-production reproducibility through numerous dyeing tests, with the aim of optimising dyeing processes. During this period, two experimental projects were conducted. The first project centred on the use of rose water as a natural dye, investigating its properties as a dye and its applicability. The second project involved the application of commercially available natural dyes, with the objective of analysing their various behaviours under different dyeing conditions.
