Chemical recycling of cotton and polyester textiles

The aim of this thesis is to separate the materials by depolymerizing the polyester using alkaline hydrolysis. The focus of the work is on how such a process should be performed without a catalyst, in order to result in both a high yield and a high purity of the cotton residue.

Development of an efficient route for combined recycling of PET and cotton from mixed fabrics

The focus of this paper is on the separation of cotton and PET (poly(ethylene terephthalate), polyester) from mixed textiles, so-called polycotton. Polycotton is one of the most common materials in service textiles used in sheets and towels at hospitals and hotels. Furthermore, cotton cellulose degradation is evaluated in this paper by analyzing the intrinsic viscosity of the cotton cellulose.
