Abstract
Abstract A substrate in the form of a fabric for seat coverings contains a higher portion of natural fibers than that of synthetic fibers. The substrate includes a mixed yarn produced of natural fibers formed by wool fibers and/or ramie fibers. The substrate further contains from 15 to 30% by weight of synthetic fibers, preferably polyester fibers.
