Description

Mesh fabric and method for knitting mesh fabric by single feeder Technical Field The invention relates to a mesh fabric and a weaving method of the mesh fabric by a single feeder. Background As a fabric in which loops (loops) are formed by two yarns in a superimposed state, a mesh fabric in which loops at predetermined positions are formed by one yarn is known. In the mesh fabric, a loop formed by two yarns and a loop formed by one yarn are mixed. The loops formed by one yarn are finer than the loops formed by two yarns. Thus, the fabric is woven into a mesh fabric having gaps at portions where the loops formed by one yarn are located. Patent document 1 discloses a single-sided knitting material knitted by two feeders in a circular knitting machine and a knitting method of the single-sided knitting material. In the knitting method described in patent document 1, a step of forming a knitting yarn loop (ground yarn loop) formed by two yarns, a step of forming a mesh yarn loop formed by one yarn, and a step of forming a pile knitting yarn loop (pile loop) formed by one yarn can be selectively performed. Therefore, the knitting method can knit mesh fabric, mesh fabric with pile yarn loops and pile fabric. The knitting method can knit various kinds of fabrics by combining knitting structures of ground loops, mesh loops, and pile loops. [ Prior Art literature ] [ Patent literature ] [ Patent document 1] Japanese patent application laid-open No. 2016-204769. Disclosure of Invention [ Problem to be solved by the invention ] The mesh fabric is woven by a combination of the ground and mesh stitches. The ground yarn loop is formed by moving a knitting needle holding two yarns to a knitting position in a state where the knitting needle is lowered and the two yarns are supported by a sinker top of a sinker (sinkers). The mesh yarn is formed by moving a knitting needle to a knitting position in a state where the knitting needle holding one yarn is lowered and the one yarn is supported by a sinker top portion of the sinker. The mesh fabric may be woven by adjusting the combination of the ratio of the number of the ground loops to the number of the mesh loops per unit area, the arrangement with respect to the ground loops, and the like. In the knitting method of the circular knitting machine described in patent document 1, since knitting is performed by using two feeders, the production amount of the knitting material is smaller than in the knitting method using one feeder. In addition, in the knitting method, the knitting position of the knitting needle in the circular knitting machine is mechanically defined by a cam (cam) for the knitting needle. Thus, the ground and mesh loops will be formed into loops of approximately the same size. Therefore, in this knitting method, when it is necessary to increase the area of the seemingly pore surrounded by the yarn on the inner side of the turns of the mesh yarn on the surface of the mesh fabric, a method of changing the arrangement and the number of the mesh yarn is used. However, in the case of a fabric in which the arrangement and number of the mesh yarn are not changed, the area of the region surrounded by the yarns inside the mesh yarn cannot be increased. Accordingly, in a method of knitting a single feeder mesh fabric using one feeder, there is a demand for a method of knitting a mesh fabric and a mesh fabric capable of increasing the area of a region surrounded by yarns inside the mesh yarn on the surface of the mesh fabric without changing the arrangement and the number of the mesh yarn. The purpose of the present invention is to provide a mesh fabric and a method for knitting a single feeder mesh fabric, wherein the area of a region (hole) surrounded by yarns inside the mesh yarn on the surface of the mesh fabric can be increased without changing the arrangement and the number of the mesh yarn. [ Means of solving the problems ] The present inventors studied a mesh fabric and a method of knitting a single feeder mesh fabric, in which the area of the mesh fabric in which the yarn on the inner side of the mesh fabric is surrounded (hereinafter, the area surrounded by the yarn on the inner side of each of the loops is simply referred to as "the area of the loop". As the area surrounded by the yarn on the inner side of each of the loops, the area of the ground loop, the area of the mesh loop, the area of the large mesh loop, and the area of the medium mesh loop) is increased without changing the arrangement and the number of the mesh loops. As a result of intensive studies, the present inventors have thought of the following constitution. The mesh fabric according to an embodiment of the present invention is knitted by a combination of a ground yarn formed by a first yarn and a second yarn in an overlapped state and a mesh yarn formed by the first yarn and not including the second yarn. The mesh yarn ring includes a large mesh yarn ring having a longer circumference than the
