New valorisation routes for mixed textiles
Belgian partners Centexbel and Procotex have worked with post-consumer textile samples both after the separation process with Ecofrag technology and coming from Vanheede and IMOG (BE). Further tests and investigations are ongoing.
The main objective, concerning mixed textile activities, is focused on defining new valorisation routes for textiles coming from urban bulky waste. In the first period of the project Centexbel and Procotex performed a screening of the different textile streams that are collected within bulky waste at Vanheede and IMOG. It was defined which streams and contaminants have to be avoided. Based on these criteria it was decided to first focus on the textiles extracted from the mattress waste stream. Post-consumer mattress textiles were delivered by Vanheede to Procotex, who adjusted the setting of their machinery to unravel and cut these materials. The obtained product was of a reasonably good quality and is currently analysed by Centexbel on its composition and fibre length. This product is currently being presented to different industrial partners with a focus on the production of needle felt, short fibre composites and natural fibre composites (NFCs). Delax is one of the partners who obtained from Procotex and Centexbel different sample materials developed from textile industrial waste. Delax will now investigate the suitability of these materials to be used as filling material inside the textile layers of a mattress.

Recently, Centexbel also received textiles from bulky waste mainly from mattresses that were treated with the Ecofrag technology and will soon investigate those materials. Delax has also delivered post-industrial mattress textile waste to Centexbel and Procotex, in order to approach as much as possible to the real process (6). It is expected to end up with textiles rolls of polyester and wool mix to be further tested in the industrial process of Delax.
