Abstract

Provided is a mesh knitted fabric and a method for knitting a one-feeder mesh knitted fabric, in which the area ratio of openings per unit area of the mesh knitted fabric is increased without changing the arrangement and the number of mesh loops. A mesh knitted fabric 1A is formed by a combination of a ground loop formed by a first yarn 2 and a second yarn 3 in an overlapped state and a mesh loop formed by the first yarn 2 without including the second yarn 3. The mesh loop includes a large mesh loop 5 having a circumference longer than that of the ground loop 4.

Description

TECHNICAL FIELD The present teaching relates to a mesh knitted fabric and a method for knitting a one-feeder mesh knitted fabric. BACKGROUND ART In a knitted fabric in which loops are formed by two yarns in an overlapped state, there is known a mesh knitted fabric in which a loop at a predetermined position is formed by a single yarn. In the mesh knitted fabric, loops formed by two yarns and loops formed by a single yarn are mixed. The loop formed by the single yarn is thinner than the loop formed by the two yarns. Accordingly, the knitted fabric is knitted as a mesh knitted fabric having gaps in portions where the loops formed by the single yarn are located. Patent Document 1 discloses a single-knit fabric knitted using two feeders in a circular knitting machine and a method for knitting the single-knit fabric. In the knitting method described in Patent Document 1, it is possible to selectively perform a step of forming a knit loop (ground loop) by two yarns, a step of forming a mesh loop by a single yarn, and a step of forming a pile loop by a single yarn. Accordingly, the knitting method can knit a mesh knitted fabric, a mesh knitted fabric having pile loops, and a pile knitted fabric. By combining the knitting structures of the ground loop, the mesh loop, and the pile loop, the knitting method can knit fabrics having various configurations. CITATION LIST PATENT DOCUMENT Patent Document 1: Japanese Patent Application Publication No. 2016-204769 SUMMARY OF INVENTION TECHNICAL PROBLEM The mesh knitted fabric is knitted by a combination of the ground loop and the mesh loop. The ground loop is formed by lowering a knitting needle holding two yarns to support the yarns on a sinker top of a sinker, and then moving the knitting needle to a knit position while the yarns remain supported on the sinker top. The mesh loop is formed by lowering a knitting needle holding a single yarn to support the yarn on the sinker top of the sinker, and then moving the knitting needle to the knit position while the yarn remains supported on the sinker top. The structure of the mesh knitted fabric can be adjusted by a combination of a ratio between the number of the ground loops and the number of the mesh loops per unit area, and the arrangement of the mesh loops relative to the ground loops. The knitting method in the circular knitting machine described in Patent Document 1 uses two feeders for knitting, and therefore the production amount of the knitted fabric is smaller compared to a knitting method using one feeder. In addition, in the knitting method, the knit position of the knitting needle in the circular knitting machine is mechanically defined by a cam for the knitting needle. Accordingly, the ground loop and the mesh loop are formed in approximately the same size. For this reason, to increase an area of a region appearing as an opening defined by the yarn of the mesh loop on the front surface of the mesh knitted fabric, this knitting method uses an approach to change the arrangement and the number of the mesh loops. However, in a knitted fabric formed on condition that the arrangement and the number of the mesh loops are not changed, it is not possible to increase the area of the inner region of the mesh loop defined by its yarn. Thus, there is a need for a method for knitting a mesh knitted fabric with an increased area of the inner region of each mesh loop defined by its yarn on the front surface of the mesh knitted fabric, without changing the arrangement and the number of the mesh loops, and also for such a mesh knitted fabric, in a method for knitting a one-feeder mesh knitted fabric using one feeder. It is, therefore, an object of the present teaching to provide a mesh knitted fabric and a method for knitting a one-feeder mesh knitted fabric, in which an area of an inner region (opening) of a mesh loop defined by its yarn on the front surface of the mesh knitted fabric is increased without changing the arrangement and the number of mesh loops. SOLUTION TO PROBLEM The inventors of the present teaching have studied a mesh knitted fabric and a method for knitting a one-feeder mesh knitted fabric, in which an area of an inner region of a mesh loop defined by its yarn in the mesh knitted fabric is increased without changing the arrangement and the number of mesh loops (Hereinafter, the inner region of each loop defined by its yarn is simply referred to as "an inner region of a loop". The inner regions of respective loops defined by their yarns are referred to as an inner region of a ground loop, an inner region of a mesh loop, an inner region of a large mesh loop, and an inner region of a medium mesh loop). As a result of diligent examination, the inventors have arrived at the following configuration. A mesh knitted fabric according to one embodiment of the present teaching is formed by a combination of: a ground loop formed by a first yarn and a second yarn in an overlapped state; and a mesh loop formed by the first ya
