Patent attributes
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.
