The present invention blocks harmful electromagnetic waves generated when electronic products are used by forming a printed layer on the surface of the fiber using a water-based ink mixed with carbon, which is a conductor, and improves heat retention, and the printed layer is buried or damaged by surface friction. It relates to a fiber having an improved coefficient of friction so that it is not, and more specifically, a fiber having an upper fabric, a cotton and a lower fabric sequentially stacked and then quilted; A printing layer formed on one or both surfaces of the fiber; And a urethane coating layer formed on the surface of the printing layer. It relates to a fiber containing graphene printed with a carbon-containing aqueous ink. |
