Raw materials and specifications:
Grapheme acrylic fiber/regenerated viscose/wool 40/40/20 485
Reasons for recommendation: As a new type of nano-material, Graphene is one of the thinnest, the strongest, the most electric-conductive, and the most extensible that has ever been discovered in the world. It is named “black gold” and “king of new material”. The yarn made of acrylic fiber with Graphene has a special quality of resisting UV lig ht, highly effectively conducting heat, continuing inhibiting bacteria, eliminating unpleasant odor, and protecting against radiation, and is widely applied.
Scope of application: Clothing
