Never say dye: Polymers will no longer need to be dyed thanks to a polymerisation technique that uses colourants

摘要

A POLYMERISATION process developed by a Leeds University spinout could lead to polyester garments never fading in the wash and food packaging that absorbs UV rays, keeping contents fresh. The Leeds University team, led by colouration technology lecturer Richard Blackburn, is commercialising the process through DyeCat. The team's patented technique introduces colourant into the polymerisation process so that polymers are pre-coloured and do not require dyeing.
