Graphene fiber is produced as a yarn by injecting graphene into a fiber process. Until now, high-purity graphene fiber has been possible only at the research stage. This is because graphene, a combination of carbon, has poor dispersibility and is not easy to synthesize with PET (polyester) polymers. So, most of the commercialized graphene fibers have  lower graphene content or compromised purity by coating the graphene material on the fiber, so there is a limit to calling it a true graphene fiber. This is the reason why commercially available graphene fibers are black or gray. However, our product can be produced with white-colored yarn using high-purity graphene, and with excellent dyeability, it can be produced with various-colored fabrics.

Typically, functional textiles are created through a coating process, which has the downside of losing effectiveness after multiple washes or high-temperature washing with detergents. Companies claiming to use graphene in their underwear or masks, employ this level of graphene coating on the fabric.

However, this approach results in graphene particles being too thick to function optimally, causing the coating to peel off quickly from the yarn and potentially impacting health adversely.

In contrast, by directly manufacturing yarn using a material that combines high-purity graphene with thin layers, we ensure the graphene is integrated into the yarn. Consequently, the graphene particles remain intact even after boiling and washing with laundry detergent, maintaining the various inherent functions of graphene. This distinguishing feature is consistently preserved and highlighted in our products.
