Title: TREATMENT PROCESS FOR TEXTILE-BASED MATERIALS
Abstract:
The present invention relates to a process for treating textile-based materials, typically textile-based waste-materials, to prepare them for further use. The treatment includes two or more chemical and/or enzymatic treatment steps, including at least one alkaline treatment step, all intended to cause at least a partial dissolution of the textile-based material. Particularly, the process is used for the treatment of cotton-based waste materials.
