Description

Investigation of enzymatic hydrolysis conditions on PET properties Recycling of poly-cotton textiles. Challenges: Current recycling processes: • Cotton: Mechanical & chemical processes established • Polyester fibre: 15% recycled material; 99% thereof from mechanical processing of bottles – open loop recycling Poly-cotton blends: • Mechanical recycling process of cotton not applicable • Chemical recycling processes of cotton not applicable • Fibre to fibre processing of polyester not well-established Therefore, further research is needed for the recycling of polyester and material combinations Aim of the work:  Investigation of the enzymatic hydrolysis process on the polymer properties on pure polyester and polyester-cotton-blends:  Assessing the impact of each process step on the molecular weight using intrinsic viscosity measurements  Producing fibres from polyester fractions and assessing the mechanical properties of the recycled material  Assessment of the impact of variation during the process and further post-hydrolysis processing
