AI Technical Summary
Technical Problem
The recycling of synthetic leathers is challenging due to their laminar structure and the difficulty in separating the PU resin from the fabric, leading to inefficient mechanical separation and environmental concerns.
Method used
A process involving the dismembering of synthetic leather, mixing with a transesterification agent, and heating to produce a polymeric dispersion that can be used to recycle synthetic leathers without mechanical delamination, reducing labor and energy consumption.
Benefits of technology
The process effectively recycles synthetic leathers into a polymeric dispersion with low amine content, which can be reused to produce new polymers like polyurethane, reducing environmental impact and saving resources.
