The invention provides a tire cord fabric and a pneumatic tire, which can improve the tire uniformity by improving the processability of the cord fabric during rolling and slitting. In the tire cord fabric (1) provided with a plurality of warp yarns (2) arranged in parallel and weft yarns (3) crossed with respect to the warp yarns (2) at a low density, the warp yarns (2) are organic fiber cords containing polyethylene terephthalate fibers or aramid fibers, the weft yarns (3) are cotton spun yarns, the fineness of the weft yarns (3) is in the range of 150 dtex to 350 dtex, and the density of the weft yarns (3) is in the range of 2.0 pieces/50 mm to 4.0 pieces/50 mm. The pneumatic tire is provided with a belt cover layer (18) formed by spirally winding a strip (10) of a rubber-coated cord fabric (1) in the circumferential direction of the tire.
提供能够改善帘子布的压延时以及分切时的加工性、由此能够改善轮胎均匀性的轮胎用帘子布以及充气轮胎。在具有平行排列的多根经纱(2)、和相对于经纱(2)以低密度交叉地打入的纬纱(3)的轮胎用帘子布(1)中,经纱(2)是包含聚对苯二甲酸乙二醇酯纤维或芳族聚酰胺纤维的有机纤维帘线,纬纱(3)是棉纺纱线,纬纱(3)的纤度处于150dtex~350dtex的范围,纬纱(3)的密度处于2.0根/50mm~4.0根/50mm的范围。充气轮胎具有将被覆有橡胶的帘子布(1)的带材(10)沿轮胎周向呈螺旋状地卷绕而成的带束覆盖层(18)。
