TLDR Microwave plasma treatment improves yak hair dyeing.
The study investigated the effects of microwave low temperature plasma (MLTP) treatment on the dyeability of yak hair fiber. The treatment aimed to address the issue of surface scales acting as barriers during dyeing. Results showed that MLTP significantly weakened and damaged the scale structure of yak hair, leading to noticeable changes in surface shape. This modification resulted in a significant improvement in the dyeing properties of the yak hair fiber.
