Patent ID: 8142872

Claim:
A vehicular upholstery polypropyleneterephthalate fiber fabric comprising: a chenille yarn and a multi-fiber yarn that are used for weft yarns and are threaded in between warp yarns in successive order; a weaving interval between the chenille yarns, which are woven in repeatedly and adjacent longitudinally back and forth, is less than twice an apparent thickness of the chenille yarn, which is specified as an observed value of the thickness of the chenille yarn; an apparent thickness of the multi-fiber yarn, which is specified as an observed value of the thickness of the multi-fiber yarn, is less than one-fifths of the apparent thickness of the chenille yarn; wherein the warp yarn selectively passes over the chenille yarn; tight portions where a large number of the warp yarns pass over the chenille yarn and rough portions where a small number of warp yarns pass over the chenille yarn are formed on the surface of the fabric; at the tight portion, the numbers of warp yarns passed over the chenille yarn are more than five threads per unit length, which corresponds to the apparent thickness of the chenille yarn; at the rough portion, the numbers of warp yarn passed over the chenille yarn are less than three threads per unit length, which corresponds to the apparent thickness of the chenille yarn; and piles of the chenille yarn and the warp yarn are respectively formed from the polypropyleneterephthalate fiber.
