The textile industry is the second most polluting industry in the world. Moreover, the recycling of clothing, mattresses and furniture is a complex and manual process, especially due to the combination of many different materials (fabrics, zips, buttons, etc.) There is an urgent need for technology that allows for more efficient re-use of textile waste streams and a move from a linear to a circular supply chain.
Resortecs contributes to this solution by inventing a bio-based and renewable thread that dissolves at high temperature. Products with seams made from this yarn are much easier to disassemble, allowing the various fabrics to be used in new ways.
We were able to prove the concept with a first prototype of the yarn. Now it is time to extensively test and validate the technical and economic feasibility and the full circular application of the yarn. Through this project, in cooperation with various partners, we have tested our sewing thread in an industrial setting and improved and optimised it where necessary.
Furthermore, we also conducted a Life Cycle Cost (LCC) and Life Cycle Assessment (LCA) to determine the economic and ecological impact of our automatic disassembly process. For these models and calculations, all actors of the value chain (brands, producers, sorters and recyclers) were contacted and questioned.
We want to further industrialise and market our sewing threads and applications in cooperation with our partners. We also want to develop a large-scale international commercial pilot of 50,000 products. There are also plans to build an automated and continuous disassembly line with an oven. Finally, we want to further develop dismountable rivet buttons and other alternative assembly techniques in fashion production.
