The characteristics of the yarn have a direct impact on the softness, stretch, recovery, comfort and overall performance of the finished garment. Even small differences in yarn behaviour can affect the final product, so understanding how different yarns respond during knitting, dyeing and finishing is very important.
Large scale automated sorting and the removal of so called hardpoints (such as zippers and buttons) can significantly reduce raw material costs. However, most chemical recycling technologies today remain unable to compete on price with oil based virgin PET, or even with mechanically recycled PET. As a result, additional financial support mechanisms will be required to bridge this cost gap during the scale up phase.
