CO₂Tex

Carbon Minds is responsible for creating a detailed model of the production chain of CO2-based textile products. To develop this model, energy and mass balances for all relevant production steps will be collected in cooperation with the project partners and on the basis of scientific literature, from the production of raw chemicals to the textile end-product. On the basis of these mass and energy balances, we are creating a process model of the CO2-based textile products, which makes it possible to analyze the environmental impacts of the products in detail. A special focus of the work is on the comparison of the two different spinning processes dry spinning and melt spinning.

At a later stage in the project, the environmental impacts of CO2-based textile products will be compared with the same fossil-based textile products (for example, those based on polyester, polyamide, or elastane). To this end, suitable reference products will first be defined in close consultation with the project partners. It is important that the conventional and CO2-based textile products have comparable properties and fulfil similar functions (e.g. their use in t-shirts or socks). We will then do a detailed, cradle-to-gate life cycle assessment for the production of the reference products . Based on the results, a comprehensive comparison of the environmental impacts in various impact categories (e.g. climate impact, toxicity, etc.) is then possible, which will allow for an evaluation of the ecological improvement potential of the novel products.
