Vehicular upholstery polypropyleneterephthalate fiber woven fabric

A vehicular upholstery polypropyleneterephthalate fiber woven fabric characterized by the following:

• a vehicular upholstery polypropyleneterephthalate fiber fabric is formed from a double woven fabric in which a face weaving textile design has a number of warp up intersections where a warp yarn passes over a weft yarn, which is more than the number of weft up intersections where the weft yarn passes over the warp yarn;
• the warp yarn is formed by twisting an intermingled yarn composed of a polypropyleneterephthalate multifilament yarn and a heat shrinkable polyetyhleneterephthalate multifilament yarn whose shrinkage percentage in boiling water is more than 15%;
• a blending ratio of the polypropyleneterephthalate multifilament yarn of the warp yarn is more than the blending ratio of the polyetyhleneterephthalate multifilament yarn of the warp yarn;
• in the warp yarn, the polyetyhleneterephthalate multifilament yarn has been shrunk by heating, and the substantial length of the polyetyhleneterephthalate multifilament yarn is shorter than the substantial length of the polypropyleneterephthalate multifilament yarn;
• the weft yarn is composed of polypropyleneterephthalate multifilament yarn;
• the single fiber finenesses of the polypropyleneterephthalate multifilament yarn and the polyetyhleneterephthalate multifilament yarn composing the warp and the weft yarns are respectively less than 7 dtex;
• and
• the basis weight of the vehicular upholstery polypropyleneterephthalate fiber fabric is from 150 g/m2 to 800 g/m2, wherein
• the face weaving textile design is a warp satin weave;
• the total fineness of the warp yarn is from 150 dtex to 400 dtex;
• the blending ratio of the polypropyleneterephthalate multifilament yarn is from 60 weight % to 80 weight % in the warp yarn;
• the total fineness of the weft yarn is from 150 dtex to 400 dtex;
• the heat shrinkable polyetyhleneterephthalate multifilament yarn forming the warp yarn has been shrunk by heating after weaving;
• and
• the density of the warp is greater than the density of the weft.
