How does micro-fibre shedding in R-PET compare to virgin polyester?
RPET also presents advantages over regular polyester in terms of micro-fibre shedding. The Swedish Foundation for Strategic Environmental Research (MISTRA) published a report in 2017 showing their findings after conducting several experiments to compare micro-fibre shedding on RPET vs. regular polyester. To the surprise of the researchers, RPET showed 55% less micro-fiber shedding than regular polyester. This research is still in process in order to establish specific elements of causation, however, the initial results are very positive for recycled polyester.
