One main challenge faced by MY-FI project is to establish a protocol for dyeing mycelium fabrics. Mycelium, the vegetative part of fungi, has an intrinsic cream to yellowish colour, which is modified by post-treatments that make it suitable for different applications in the fashion and automotive sectors, among others. Scientists and researchers from ITECH and LEITAT are currently working on dyeing activities to obtain an aesthetic material and maintain its intrinsic properties. Natural and sustainable dyes, as well as bio-based auxiliary products are preferred during research activities for dyeing protocol development.

LEITAT explored and developed several dyeing protocols, including both natural and synthetic substances, as well as low-pressure plasma pre-treatment.

The most performing dyeing protocol will be defined in the upcoming weeks, according to the industrial requirements.
