The majority of textile fibers are still made from petroleum-based raw materials. However, the production of biogenic fibers such as cotton also has a significant environmental impact. The textile industry is therefore increasingly turning to so-called regenerated cellulose fibers such as Lyocell, which are much more environmentally friendly to produce. In the Texroh project, researchers at the Technical University of Dresden and the Thuringian Institute for Textile and Plastics Research in Rudolstadt are seeking to tap into new sources of raw materials for the production of regenerated cellulose fibers for a resource-efficient Lyocell process.

Lyocell fibers from residual and waste materials

Currently, chemical pulp from wood is used in Lyocell production. Researchers are therefore focusing on agricultural residues and waste materials as well as old cotton textiles, which can be used to produce high-purity chemical pulp. In addition, suitable pulping processes for pulp production are to be established, taking into account economic and ecological aspects, the pulps obtained are to be modified accordingly for Lyocell production, and spinning tests with the sustainable Lyocell are to be carried out on a laboratory and pilot plant scale.

Basis for a circular textile economy

By establishing new sustainable raw materials for Lyocell production, the research team aims to lay the foundation for a sustainable and regional circular textile economy.

The three-year Texroh joint project will be funded by the Federal Ministry of Agriculture, Food, and Rural Affairs (BMLEH) until October 2027.
