The idea behind the project consists of a substantial innovation in the field of textile chemistry which will make it possible to obtain synthetic fibers starting from wool fiber waste. In particular, the idea is based on the recovery of industrial wool waste consisting of textile waste, sub-products, combing blousses, waste, fiber and using them for the preparation of new yarns through a dissolution and regeneration process which will be developed in plan. The process will be based on dissolution with ionic liquids (IL), an innovative class of compounds found to be capable of dissolving most natural fibres, including wool, which are instead insoluble in common organic solvents and water.
