Abstract: Invention-wise three-dimensional net made by warp knitting has high shape retainability in three-dimensional cords defining three-dimensional mesh spaces, capability of suppressing direction dependency, superiority in structural stability and pressure resistance, capability of retaining a suitable degree of elasticity and formation of three-dimensional cords simply by imparting tension, high void content, and lightweight, which are suitable for various applications.

Abstract: The invention is aimed to provide a three-dimensional marquisette-like knitted fabric, that is good in air retainability, air and water conductibility, light transmittance, as well as dimensional stability and shape retainability in the knitting and knitting-width directions, and in linearity; and has unevenness and slippage preventing property on its surface, thus being suitable in various uses. To this end, a three-dimensional marquisette-like structure is made as follows. A double-web knitted fabric is made by warp knitting, and is preferably comprised of the front and back mesh webs (1, 2) and connecting yarns (3) passed between the mesh webs alternately. At least one of the mesh webs (1, 2) has a marquisette-like construction formed by the rows of chain stitches (11, 21) and inlay yarn (5).

Abstract: The present invention provides a water retention net having water retentivity not obtainable in conventional nets, usable suitably, for example, to a vegetation treatment for slopes of arid places or greening treatment of deserts or the like, wherein a water absorbing resin or a water retention agent 10 mainly comprising the water absorbing resin is deposited by a coating means to at least one side of a net prepared by warp knitting, or a steric net in which a string portion 1 forming net meshes 2 has air transmittable and water transmittable gap spaces, for example, a steric structure net prepared by warp knitting, so as to provide water transmittability due to the steric structure and water retentivity due to the water retention agent together, and provide a satisfactory function of supplying water.

Abstract: A three-dimensional net includes front and rear base nets interconnected with connecting yarn with a predetermined space therebetween. The front and rear base nets each include braid parts forming a meshed structure which presents mesh openings bounded by intersections of the braid parts, each of the braid parts including at least one wale. The mesh openings of a first of the front and rear base nets is larger than the mesh openings of a second of the front and rear base nets, and the front and rear base nets are connected together by passing the connecting yarns between all the braid parts of the first base net and a corresponding portion of the braid parts of the second base net in positions opposed to the braid parts of the first net.

Abstract: This invention relates to a three-dimensionally constructed net A for use in various applications including a water collecting and discharging net or a protection net in the faces of slopes in created land or residential sites, a plant protection net, such as a spray sowing net and so on, a building protecting net, an agricultural light-shielding net and a medical net. The net may be conveniently formed by knitting or weaving, so that cord portions which define the meshes are made in hollow three-dimensional construction capable of ventilation and water passage. Thereby, despite the fact that the net is a thick, three-dimensional body, the possession of a void content by the cord portions improves the ventilating and water collecting and discharging effects and saves weight, facilitating the handling and installing of the net, so that the net can be easily handled and well suited for the above-mentioned applications.
