Project Chrysalis – from container to textile

Design researcher Michelle Baggerman and material designer Jessica den Hartog present Project Chrysalis: In the Netherlands just a fraction of the 25kg of plastic waste generated p.p.p.y. is recycled. Plastics like PET and PP are increasingly recycled for high-grade applications but HDPE is mostly down-cycled. Project Chrysalis is a research into developing recycled monofilament yarns for closed-loop textile products out of HDPE sourced from household waste.

Towards textile to textile recycling: Is there a sustainable solution?

Polyester is one of the most widely used polymers all around the world, with applications that span from packaging to textiles. Depending on its use, the material composition can be quite different, with a polyester amount ranging from more than 99% for PET bottles to 25% for some textile products. The most common method for the recycling of plastic waste is mechanical recycling. This process typically includes collection, sorting, washing, and grinding of the material, but a breakdown of polymer chains occurs when the resin goes through multiple cycles, degrading its intrinsic viscosity and limiting the number of times the process can be repeated.

CO2 emissions saved by reusing used clothing

About 550 kilos from containers of the Foundation ‘Training and Work’ is the total weight of used clothing that has analyzed in this study characterizing the fibers that make up T-shirts, shirts, coats, pants, jackets and all kinds of clothing which are dumped in textile waste collection containers. Of the total used clothing used in the containers analyzed, 62% of the garments are reusable and 37% recyclable. As for the fibers with which the garments are made, the study concludes that cotton predominates, with 50% in the case of recyclable clothing and 60% in the case of reusable clothing.

State of the art in sustainable fibre technology

Biobased

A presentation by Prof. Dr.-Ing. habil. Dipl.-Wirt. Ing. Gunnar Seide, Chair for Polymer Engineering, Maastricht University – Aachen Maastricht Institute for Biobased Materials (AMIBM).

Textiles are one of the most important consumer goods and the textile industry is one of the largest and most interconnected industries in the world. Clothing plays a role, but so do technical products such as building materials, reinforcing materials for tyres, medical products, packaging, lightweight materials and much more.
