  • Patent number: 8056373
    Abstract: An object of the present invention is to provide a light-transmitting sheet material capable of transmitting sufficient amount of light and providing high blinding effect. A sheet material (1) includes a front fabric (2), a back fabric (3), and light-shielding layers (4), and is shaped such that the front fabric (2) and the back fabric (3) are held with a predetermined distance therebetween by fixing entire constituent yarns by resin treatment. The front fabric (2) and the back fabric (3) are formed into a planar shape by arranging stitch rows of chain stitches, knitted in a warp direction, in a weft direction at a predetermined interval and by knitting an insertion yarn alternately in adjoining stitch rows by a predetermined length.
