As part of the work package that aims to the elimination of chemical products from the acrylic textile substrate, REACT partner Soft Chemicals has been recently involved in the development of a consolidated system to treat frayed acrylic waste material.
The removal of chemical products is key to the success of the envisioned REACT process: mainly composed by resins and water-repellent finishing, such products could be hazardous and could affect the recyclability of waste material.
The frayed material described is the result of the unravelling process applied to the departure acrylic textile samples: following this transformation, the material should allow better fibre penetration and more efficient chemicals removal, as they are bathed in agents designed to eliminate hazardous substances.
A first round of trials has been performed on W8A1 fabric for awnings and W7A selvedges with awnings finish. The results are being currently analysed by University of Bergamo and Ghent University, together with leading partner CENTROCOT. The total amount of W8A1 and W7A treated was around 500 kg.
The treatment process itself creates waste water that will need subsequent purification. At the end of the trials conducted, the waste water has been collected in order to be processed in the next phase of REACT’s recycling process: follow us for further updates on how partners are working to achieve this task.
