USING A MORPHOLOGICAL CHART TO DEVELOP FASHION PRODUCTS FROM RECYCLED KNIT WASTE

This article aims to investigate and experiment environmentally sustainable solutions using cotton knit waste and hand knitting to develop new fashion products. The knit waste came from imperfect knit fabrics discarded by industries and circular knit garments discarded by consumers. The tool used as a creative mean of development was the morphological chart, which allowed approximately one hundred and fifty ideas of garments to be generated. Five ideas were identified as main product concept. A prototype of a vest was made to test the viability of the use of the morphological chart do develop a creative fashion product. The reproducibility of the methodology was successfully tested by handcraft artists that work with hand knitting.

Assessment of coconut fibers for textile applications

Brazil is the fourth larger producer in coconut fruit in the world. However, the industry processes only asmall portion of coconut byproducts, which have caused serious environmental problems. The purpose of thisarticle is to test an alternative for the recovery of coconut byproduct. In a series of experiments, recoveredcoconut fibers (coir) were treated to be employ in textile application. After initial classification and sampling,the fine coconut fibers were subjected to a simultaneous scouring and pre-bleaching process in a mild alkalisolution together with hydrogen peroxide (H2O2). The fibers were first subjected to this treatment for 10minutes at 80°C and then again for 20 minutes at the boiling point. The samples were then treated with a cationicsoftener for 10 minutes at 60°C. After this process, the physical and mechanical properties were measuredand values proved not to be statistically significant. The article indicates some of the main obstacleswhen handling coconut fiber for textile applications and reveals that besides elongation, softness and homogeneityare essential for coconut fibers spinning. Findings in this investigation showed some improved resultsin relation to the previous literature in two aspects: Firstly, because the treatment did not harm the fibersquality; secondly, because due to the treatment the coconut fibers could be arranged in fibrous strands, whichfacilitated spinning and weaving for use in textile applications.Keywords: coconut fiber, coir, scouring, softening, textile

Assessment and technological forecasting in the textile industry : from first industrial revolution to the industry 4.0

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 aspects113193202COORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESNão te

USO DA MATRIZ MORFOLÓGICA PARA DESENVOLVIMENTO DE PRODUTOS DE MODA A PARTIR DE MATÉRIA-PRIMA RECILADA

O presente artigo tem como objetivo investigar e experimentar soluções ambientalmente sustentáveis, utilizando resíduos de malharia circular de algodão e o tricô, para a fabricação de novos produtos de moda. Como matérias-primas principais foram utilizados tecidos defeituosos descartados por empresas e peças descartadas por consumidores. A ferramenta usada para o desenvolvimento do processo criativo foi a matriz morfológica, com esta técnica foram geradas aproximadamente cento e cinquenta ideias de produtos de vestuário. Cinco ideias de concepção de produtos foram identificadas como principais. Foi confeccionado um protótipo de um colete curto com o objetivo de mostrar a viabilidade da aplicação da matriz morfológica para o desenvolvimento de produtos criativos em moda. A reprodutibilidade da metodologia proposta foi testada com sucesso por artesãos que trabalham com técnicas de tricô manual

Materiais de descarte das Micro e Pequenas Confecções - Uma proposta de procedimento para o desenvolvimento de produtos sustentáveis na indústria têxtil

Esta pesquisa teve como objetivo propor procedimentos, utilizando como referência a metodologia projetual de Löbach para desenvolvimento de produtos sustentáveis têxteis a partir de sobras dos materiais das micro e pequenas confecções. A Metodologia utilizada foi a pesquisa bibliográfica, que constitui o procedimento básico para os estudos monográficos, e a pesquisa exploratória, pois não requer a formulação de hipóteses para serem testadas. Ela se restringe por definir objetivos, buscar mais informações sobre determinado assunto de estudo e identificar qual o melhor método a ser utilizado. No caso deste projeto, a ideia foi adaptar a sintetização de Löbach no processo de design, relacionando-o com o processo de resolução de problemas e o processo criativo, em quatro iniciativas essenciais: definir claramente o problema (preparação); reunir informações sobre o problema, analisá-las e relacioná-las criativamente entre si (geração); criar alternativas de soluções para o problema, julgando-as segundo critérios estabelecidos (avaliação) e desenvolver a alternativa mais adequada, concretizando-a (realização). Após a elaboração do projeto, comprovou-se que a metodologia utilizada se mostrou viável para o desenvolvimento de produtos sustentáveis, voltados para a sociedade e consumo

Mechanical characterization of the green coconut fiber for application in the footwear industry

In the tropical countries, the green coconut water consumption generates a great problem with the fruit \ud final destination. To minimize this problem, it is necessary to find applicability to the residues. In this \ud sense, this study had as its objective to investigate the characteristics of the green coconut fiber, from the \ud fruit disposed in the city of Francisco Morato – Sao Paulo, and to compare them to the characteristics from \ud other natural fibers, to check the viability of application of these fibers in the manufacturing of shoe parts. \ud It was made a biological maceration on the fibers and traction and microscopy tests were run. The results \ud showed that the green coconut fibers have potential related to other natural fibers studied in literature, to \ud be used as reinforcement in the manufacturing of shoe parts and other design product

Estamparia digital: relações entre tecnologia, desenho e superfície têxtil

Instruments and techniques used in the Textile printing process often influence the result of image reproduction. Information on the different types of digital textile printing technologies was collected through bibliographic research as well as on printed samples. For the purpose of analyzing how digital textile printing influences image reproduction, this study presents different samples with different fabrics to understand those relevant factors. 100% cotton and 100% polyester plain weave fabrics with different patterns and 100% polyester jersey were selected in the retail market for printing tests with a single file containing several images.The images were printed at three resolutions: 300, 150 and 72 PPI. The 150 PPI images were excluded from this article, as they did not have significant differences compared to theothers. The experimental results show that there are differences between the characteristics studied in the images with a resolution of 300 PPI and 72 PPI, which allows a set of practical information regarding digital printing technology on textile substrates to be organized.Il risultato della riproduzione dell'immagine nella stampa tessile è spesso influenzato dagli strumenti e dalle tecniche utilizzate nel suo processo di produzione. Attraverso ricerche bibliografiche e prove di stampa, sono state raccolte informazioni sulle tecnologie utilizzate nella stampa digitale, al fine di analizzare l'influenza di questo processo sulla stampa e riproduzione di immagini, su diversi substrati tessili e per comprendere i fattori rilevanti di questo processo. Sul mercato sono stati selezionati tessuti piatti di varie fantasie, secondo la composizione 100% cotone e 100% poliestere e la composizione mezza maglia 100% poliestere, questi sono stati stampati da un unico file con immagini differenti.
