Purpose – The purpose of this paper is to present a comparative study on the characteristics of knitted fabrics used in the manufacturing of apparel, which are produced from organic cotton, lyocell and soybean protein fiber (SPF). It is important for both the environment and society that textile industry continues to adopt more ecofriendly materials and furthermore, pushes to increase awareness regarding these material choices available to the consumer and the corresponding impacts of consumers’ decisions. The use of sustainable fibers may be a starting point for changing the industrial paradigm of the textile industry. Design/methodology/approach – The research presented herein analyzes the potential use of three raw materials used in the development of knitted fabrics: organic cotton, lyocell and SPF. The experimental trials, based on norms, determined the weight, pilling, rupture pressure resistance, absorption by capillarity, dimensional alteration and elasticity. The significance of the experimental results was verified through the analysis of variance, with a confidence interval of 95 percent (p=0.05) and the determination of the optimal regulation of the machine was made through an analysis of the response surface. Findings – The results indicate that each of the studied materials are suitable for textile application; however, the fabrics manufactured from soybean yarn, compared to those manufactured from organic cotton or lyocell, have a higher potential to meet the needs of the costumer. Social implications – The discussion regarding sustainability is far reaching on the ways it interacts with human life. As such, the latent need for meeting this new demand presents a unique opportunity for the development of new processes and products. In the case of the textile industry, initiatives are gradually being adopted that make the processes used by the supply chain less damaging to the environment. Clothing and fashion are highly visible elements of society, so consequently, the textile industry serves as an excellent candidate for promoting a sustainable and eco-friendly mindset. Originality/value – The incorporation of sustainable fibers can serve as a starting point for change to the industrial paradigm existing within the textile industry. To this point, this study intended to analyze the potential implementation of three raw materials – organic cotton, lyocell and SPF – in the development of knitted fabrics. The results indicated that these materials are adequate for textile applications.
Esta revisão explora problema do pós-consumo do coco verde no Brasil. Inicialmente foi feita uma investigação sobre os aspectos gerais da indústria do coco e de seus derivados. A origem da geração dos subprodutos do coco e as consequências de tal indústria para a gestão rural e urbana também foram apontados. Em seguida, foram pesquisados artigos e relatórios científicos para conferir as propriedades e as possíveis aplicações dos subprodutos de coco. Para complementar, foram apresentadas diferentes visões sobre o conceito teórico do desenvolvimento sustentável aplicado ao design de produtos. Como resultado, a literatura cobre uma variada gama de aplicações para os subprodutos do coco em engenharia, entretanto, carece de pesquisas na área de gestão e logística da cadeia do coco. Conclui-se que os conceitos de sustentabilidade devem ser interpretados de forma ampla e objetiva em pesquisas futuras a fim de viabilizar o consumo e o pós-consumo sustentável da fruta.
In recent years, there has been a substantial increase in the production of knitted fabrics with textured synthetic yarns in circular knitting machines. However, there are few studies for this type of yarn on the effects of variations in tension on circular knitting machines. In this work, we examine the variation in yarn tension before the positive feed and analyze its influence on the properties and quality of knitted fabrics produced with spun yarn and textured synthetic yarn. Knitted fabrics were produced with spun cotton yarn and textured microfiber nylon yarn (polyamide), which were analyzed with respect to loop length. The results demonstrate the importance of controlling the yarn feed tension when working with textured yarns, even with the use of a positive feed, in contrast to what occurs when spun yarn is used.
Each Industrial Revolution played a key role in the production-consumption pattern of textile products. Given the complexity of the Textile and Apparel Industry, the production systems have varying degrees of conceptual and technological innovation. Thus, the objective of this research is to present a model that includes the projection of technological changes in the production and consumption of textiles from the contrast between the descriptions of patents, scientific articles, and trends and tools of the Industry 4.0. It was possible to infer that the components of the Textile and Apparel Industry are undergoing an evolutionary process, which includes the automation of machinery parts and processes. The technological tools that characterize the Industry 4.0 are not yet fully integrated into textile production, and the challenge for the textile industry is to keep up with these innovations that impact on production, on business models, on consumer habits, and on social aspects.
RESUMOO objetivo da presente pesquisa foi analisar como a customização em massa e o movimento Maker estão modificando a produção e consumo de artigos têxteis e de confecção e quais são os possíveis desdobramentos tecnológicos desses novos paradigmas. Para tanto, o procedimento metodológico adotado na presente pesquisa têm caráter predominantemente expositivo baseado em levantamento bibliográfico. A customização em massa e o movimento Maker têm em comum a proposição de um consumidor ativo que participa nas decisões de construção, modificação e fabricação de diferentes projetos de produto por meio do uso de ferramentas de Tecnologia da Informação e Comunicação (TIC). Como resultados, notou-se que a Internet das Coisas, a robótica, a impressão 3D, os microprocessadores com preços acessíveis e o ensino de linguagem de programação são elementos decisivos na difusão do movimento Maker e da customização em massa. A Fábrica Inteligente e a mini-fábrica serão dois modelos industriais amplamente utilizados. O desenvolvimento de didáticas de ensino, de modelos ágeis para o desenvolvimento e gestão de novos produtos e de ferramentas de comunicação com o consumidor são temas para pesquisas futuras de modo a consolidar esses novos paradigmas.Palavras chave: Movimento Maker, Customização em Massa, Indústria Têxtil,
