The present invention teaches a vehicular upholstery PPT-fiber fabric that is formed from a double woven fabric in which a face weaving textile design has a number of intersections, called warp up intersections where a warp yarn passes over a weft yarn, and these are more than the number of intersections, called weft up intersection, where a weft yarn passes over a warp yarn. The warp yarn is formed by twisting an intermingled yarn composed of a PPT-multi-filament yarn and a high heat shrinkable PET-multifilament yarn whose shrinkage percentage in boiling water is more than 15%. An intermingle ratio of the PPT-multifilament yarn of the warp yarn is more than the intermingle ratio of the PET-multifilament yarn of the warp yarn. In the warp yarn, the PET-multifilament yarn is shrunk by heating, so that the substantial length of the PET-multifilament yarn becomes shorter than the substantial length of the PPT-multifilament yarn. The weft yarn is composed of PPT-multifilament yarn.

Vehicular upholstery polypropyleneterephthalate fiber woven fabric

Vehicular upholstery fabric is woven by using chenille yarn and multi-fiber yarn for weft yarns. The weaving interval between chenille yarns is set up less than the apparent thickness of the chenille yarn, which is specified as an observed value of the thickness. The apparent thickness of the multi-fiber yarn is less than one-fifth of the apparent thickness of the chenille yarn. There are tight portions where a great number of warp yarns passes over the chenille yarn, and rough portions, where a small number of warp yarns passes over the chenille yarn that is formed on the surface of fabric. PPT-fibers are used for the pile of the chenille yarn and the warp yarn.
