摘要： A netlike sheet comprises woven warp and weft yarns, either the warp yarns or the weft yarns being a five-layered yarn composed of two stretched layers of polyolefin resin and layers of polyolefin resin having a melting point lower than that of the former disposed between the two stretched layers an on the outer surfaces thereof and the other being the same the five-layered yarn or a three-layered yarn composed of a central stretched layer of polyolefin resin and layers of polyolefin resin having a melting point lower than that of the former, which are disposed on both side of the stretched layer, the warp and weft yarns being heat bonded at intersections of these yarns. The netlike sheet exhibits good stiffness and excellent retention of sheet-like shape and the meshes of the net are stable during using the same.
