Abstract Natural dyes are gaining interest as a more ecological approach to textile coloration, well for slow fashion and the bioeconomy. The use of local raw materials is way valuing small producers recovering traditional knowledge. In this context, current investigation was developed study lignocellulose‐based Stryphnodendron adstringens (Mart.) Coville (known “barbatimão”) bark extract, from native tree in Brazil, natural dye dyeing. Physical–chemical analyses were performed on...
The ability to add value waste materials from industrial operations has come the attention of wood processing industry, with reports, for example, extracts bark tree conveying colour and UV protection textile fibres. objective present work was expand our developments in this arena by using Copaifera langsdorffii Desf. extract as a natural dye dyeing. A complete 2³-statistical experimental design central point elaborated. results showed that optimal dyeing conditions were 98 °C, 60 min,...
The present research aims to the technological evolution of sportwear production by comparing conventional and new systems. For this, following systems were defined: knitting (T-shirt shoe upper), seamless (T-shirt) 3D (shoe upper). definition these objects study was based on that points walking as most practiced physical activity Brazilians. methodological procedure adopted in is predominantly exploratory. Sportwear can be produced process or processes. In process, there are many steps for...
RESUMO Neste trabalho, foram produzidas nanocápsulas contendo material de mudança fase (“Phase Change Material” -PCM) por meio do processo encapsulação via polimerização em emulsão, utilizando a cera palmitato cetila como encapsulado e o monômero metacrilato metila encapsulante, através duas metodologias distintas. A relação mássica cera/monômero também foi avaliada na produção das nanocápsulas. As amostras submetidas caracterizações, com objetivo avaliar estabilidade integridade física após...
A adoção de normas técnicas no intuito regulamentar os Equipamentos Proteção Individual Brasil, além tentar fornecer condições trabalho mais seguras, tem por consequência a diminuição do valor gasto com benefícios acidentários e aposentadorias especiais. Recentemente, Secretaria Especial Previdência Trabalho (SESPREVT) adotou diversas vistas à proteção trabalhador que utiliza motosserras tange pernas, pés, mãos tronco. O IPT se mostrou uma vez pioneiro na adequação laboratório capacitação...
