Abstract [en]

Microplastics in the environment are a subject of intense research as they pose a potential threat to marine organisms. Plastic fibers from textiles have been indicated as a major source of this type of contaminant, entering the oceans via wastewater and diverse non-point sources. Their presence is also documented in terrestrial samples. In this study, the amount of microfibers shedding from synthetic textiles was measured for three materials (acrylic, nylon, polyester), knit using different gauges and techniques. All textiles were found to shed, but polyester fleece fabrics shed the greatest amounts, averaging 7360 fibers/m−2/L−1 in one wash, compared with polyester fabrics which shed 87 fibers/m−2/L−1. We found that loose textile constructions shed more, as did worn fabrics, and high twist yarns are to be preferred for shed reduction. Since fiber from clothing is a potentially important source of microplastics, we suggest that smarter textile construction, prewashing and vacuum exhaustion at production sites, and use of more efficient filters in household washing machines could help mitigate this problem.

Abstract [en]

This is the final product construction report for the From Roll to Bag project. The purpose of this report is to present the implementation of the new pattern technology to selected products and to present the modularity for consumer selection. For fulfilling the tasks (5.1 and 5.2) two garments where chosen, one jacket and one shirt, and customization options regarding fit, model, colour and function were developed for each of them. This includes implementation of novel pattern technology to products, graphics, a product architecture with customisation options and initial production tests to verify perfect fit in production and later in use. The more challenging part was to guarantee manufacturability as the patterns require automated manufacturing equipment due to their detailed construction and the pattern matching. Such equipment includes a cutter with a scanner that identifies the outline of the printed pattern and cuts accoringly. If garments with less detailed graphics are considered for production, pre-dyed fabrics can be used and that requires less investments in manufacturing equipment. Such set up would miss one point of the project but in the tradeoff between investment cost and product price point it may be a viable solution. The garments and customization modules are also fit for production but in order to achieve a detailed production evaluation with exact production times and material consumption a long run of products is needed. Considerations about customer’s experiences in this type value chains are also discussed.

Abstract [sv]

Syftet med denna undersökning är att undersöka om korta moment inspirerade av problembaserat lärande under uppstarten av en längre kurs på högskolenivå kan förbättra förutsättningarna för lärande, inom det naturvetenskapliga ämnet och designämnet. För att undersöka frågeställningen genomfördes en enkätundersökning med studenter på Textilingenjörsprogrammet och Textildesignprogrammet på Textilhögskolan i Borås. Textilingenjörerna hade under inledningen av en längre kurs i Polymerteknologi ett introduktionsmoment där studenterna fick en konsumentprodukt tilldelad. Under inledningen av designprojekt hade studenterna på Textildesignprogrammet workshops där de arbetade individuellt eller i grupp. Uppgiften handlade om att utveckla en lösning för skyddad sömn vid en utsatt nödsituation eller att konstruera vävbindningar med hjälp av sin kropp. Enkätundersökningen visade att de flesta som deltagit i introduktionsmomentet av textil-ingenjörerna tyckte att det kändes stimulerande att gruppen själv styrde projektets genomförande vilket inte riktigt alla på textildesignprogrammet höll med om. Här hade man velat ha mer handledning under workshopen. Textilingenjörsstudenterna uppgav i enkäten att introduktionsmomentet hade avgörande betydelse för intresset av hela kursen medan textildesignstudenterna uppgav att introduktionsmomentet inte var lika avgörande för intresset under den fortsatta kursen. Slutligen visade enkätundersökningen att textilingenjörerna i högre grad ville se mer av studentcentrerat lärande utan lärarstyrning.
