Chemical Recycling of a Textile Blend from Polyester and Viscose, Part II: Mechanism and Reactivity during Alkaline Hydrolysis of Textile Polyester

Chemical recycling of textiles holds the potential to yield materials equal quality and value as products from virgin feedstock. Selective depolymerization textile polyester (PET) regenerated cellulose/PET blends, by means alkaline hydrolysis, renders monomers PET while cellulose remains in fiber form. Here, we present mechanism reactivity during hydrolysis. Part I this article series focuses on part a possible industrialization such process. The kinetics reaction for hydrolysis packaging or bulk are well described scientific literature; however, information is sparse. We find that rate not affected disintegrating fabric increase its surface area. ascribe yarn structure, where texturing low density assures high accessibility even without disintegration. reaction, similar polyester, shown be specific proceeds via endwise peeling. Finally, show product terephthalic acid pure obtained yields.
