Highly air-permeable woven fabric resistant to washing

Abstract

An object of the present invention is to provide a highly air-permeable woven fabric whose air permeability does not easily deteriorate even after repetitive washing and which has a good fabric quality. The woven fabric of the present invention comprises warp threads constituted by substantially quadrilateral shaped filaments and weft threads constituted by substantially quadrilateral shaped filaments. The warp threads and the weft threads overlap each other in an alternating manner forming crossover points comprising front threads and back threads, such that the warp threads and the weft threads alternate constituting the front threads. The crossover points comprise first crossover points and second crossover points. The first crossover points are the crossover points where the substantially quadrilateral shaped filaments constituting the front threads are aligned in a line. The second crossover points are the crossover points where at least 60% of the substantially quadrilateral shaped filaments constituting the front threads are aligned in a line. The rest of the substantially quadrilateral shaped filaments constituting the front threads overlap above and below in a thickness direction of the woven fabric, wherein, in a structure constituting five warp threads, six weft threads, and 30 crossover points, the total number of the first crossover points among thirty crossover points is not less than 10% and not more than 90%.
