Graphene viscose composite fiber is composed of single-layer graphene oxide and viscose spinning solution. The unique dispersion process and spinning process design ensure that graphene is evenly dispersed in the viscose fiber. This new composite fiber has many functions such as far-infrared emission, anti-bacterial and anti mite, anti ultraviolet, negative ion emission, etc. it has been certified by a number of domestic and foreign authoritative testing institutions to protect health.
