A multi -layered yarn, comprising: a central core fiber; an inner fiber wrapped about the central core fiber in an inner helical configuration; and an outer fiber wrapped about the central core fiber and over the inner fiber in an outer helical configuration that is oppositely oriented to the inner helical configuration, to form a protruding cross-hatch pattern having multiple indentations on the surface of the multi-layered yarn, thereby increasing the surface area of the multi-layered yarn.
