Resortecs Smart stitch

Recycling clothes has never been easier

Resortecs Smart stitch is a sewing thread that melts at high temperatures, and makes for cheap and easy disassembly and recycling. Resortecs enables the entire textiles industry to achieve full circularity in a straightforward and affordable manner, or, at the very least, to push companies in that direction.

The textiles industry is the second most polluting industry in the world. Every second, the equivalent of one full dump truck full of textiles (approx. 2.6 tonnes) is landfilled or incinerated worldwide. This has a major social and environmental impact. We urgently need technology that allows us to reuse textile ‘waste’ in a more efficient manner and we need to switch from a linear ‘take-make-dispose’ model to a circular supply chain.

Recycling clothes, mattresses and furniture is a complex, manual process, where operators are confronted with a range of materials/fabrics, zips and buttons Resortecs solves this problem thanks to a biodegradable and renewable thread that simply dissolves at high temperatures When used on seams, the entire product can easily be disassembled, allowing for the different fabrics to be reused time and time again

Several working prototypes of this thread have been developed. The first prototype proved the concept and served to test the yarns in partnership with various players and companies in the textiles industry. These tests served as the basis for the definition of additional technical requirements, which were further developed in a second research and development phase. Based on the materials scan, which was carried out in collaboration with the Centexbel research centre, the project also assessed whether there are any other polymers, either in industry or in academia, that meet the requirements and can be used for the Resortecs application. Several options were identified and selected, including a biocompostable polyester that can be produced using renewables.

The plan is to test these new yarns and the entire circular application in a large-scale study, which will be conducted with the assistance of the Dutch incubator ‘Fashion for Good’ and in collaboration with textile producers.
