Description

  The present invention relates to a ball collecting sheet laid on the ground surface of a golf driving range.

  The ground surface of the golf driving range is inclined in a certain direction in order to collect golf balls at predetermined locations. A cushioning sheet is laid on the inclined surface to prevent damage to the golf ball when it lands. For example, natural turf, artificial turf, non-woven fabric, rubber sheet, foamed resin sheet and the like are laid.

  As this cushioning sheet, a double raschel knitted fabric described in Patent Document 1 is also used. Double raschel knitted fabric has excellent cushioning properties and good water permeability. Therefore, it is preferable because the golf ball is hardly damaged and the drainage is good.

  However, in the double raschel knitted fabric described in Patent Document 1, since the connecting yarns connecting the outer material and the lining material are upright, the structure provided on the outer material is likely to be displaced. When the structure is displaced, sand enters between the yarns constituting the outer material, and when the texture is displaced again in this state, the yarn is easily cut by friction. In addition, even when the yarn constituting the double raschel knitted fabric is deteriorated due to change with time due to the influence of sunlight or the like, the yarn is easily cut. When the yarns that make up the double raschel knitted fabric, especially the yarns that make up the outer material, are cut, the structure of the outer material is damaged, and although the golf ball was initially easy to roll, Has become difficult to roll and cannot automatically collect balls.

  The problem of the present invention is that in a ball collecting sheet made of a double raschel knitted fabric, the surface of the knitted fabric is less likely to be displaced, and the yarns constituting the knitted fabric are less likely to change with time. It is to be able to collect well.

  In order to solve the above-described problems, the present invention connects a double raschel knitted fabric that supports the knitting yarn constituting the outer fabric from both the left and right directions without causing the connecting yarn that connects the outer fabric and the lining to be upright. The double raschel knitted fabric is kneaded with a weathering agent to prevent deterioration.

  That is, the present invention provides a golf practice field ball-collecting sheet comprising a double raschel knitted fabric composed of a outer material and a lining material, and a connecting thread connecting the outer material and the lining material, wherein the outer material comprises two or more chain stitches. It is a mesh-like structure with a substantially hexagonal or rhombus-shaped watermark by knitting yarn knitted with yarn, and the lining is a plain structure knitted with chain knitting yarn and insertion yarn, The connecting yarn is a structure that extends from the knitting yarn of the outer fabric to the left and right by two ridges, and connects the chain knitting yarn of the lining material at an interval, and constitutes the outer fabric and the lining fabric. The yarn is a multi-filament yarn that is kneaded with a weathering agent, and the yarn that constitutes the connecting yarn is a monofilament yarn that is kneaded with a weathering agent. This is related to the practice field collection sheet.

  The present invention can be knitted by a conventionally known double raschel knitting machine. A double raschel knitted fabric knitted with a double raschel knitting machine is composed of a surface material 1 and a lining material 2 and a connecting yarn 3 that connects the surface material 1 and the lining material 2 (FIG. 1).

  The outer material 1 has a mesh-like structure having a substantially hexagonal or diamond-shaped openwork 4. FIG. 2 shows an organization of the outer surface having a hexagonal watermark 4. The net legs 5 are formed of knitting yarns 7 knitted with chain knitting yarns 6a and 6b (FIG. 3). FIG. 3 shows an example in which the knitting yarn 7 is knitted with two chain knitting yarns 6a and 6b, but may be formed with three or more chain knitting yarns 6a, 6b, 6c. .

  The lining 2 is a plain structure knitted by the chain knitting yarn 6m and the insertion yarn 8 (FIG. 4). This structure is a basic structure of the Russell knitting, and is a warp knitting structure composed of a chain knitting yarn 6m arranged in each wale and an insertion yarn 7 arranged in each course.

  The outer material 1 and the lining 2 are connected by a connecting thread 3. In the present invention, the connecting yarn 3 is supplied by two scissors. That is, the connecting yarn 3a is supplied by one hook, and the connecting yarn 3b is supplied by another one hook. The connecting yarns 3a and 3b connect the knitting yarn 7 of the outer fabric 1 and the chain knitting yarn 6m of the lining 2 respectively. The knitting structure diagram of the connecting yarns 3a and 3b is, for example, as shown in FIG.

  The connecting yarns 3a and 3b are divided and extended to the left and right of the knitting yarn 7 of the outer fabric 1 (FIG. 6). The connecting yarns 3 a and 3 b are connected to the chain knitting yarn 6 m of the lining 2. At this time, as shown in FIG. 6, there is one chain knitting yarn 6m between the chain knitting yarn 6m to which the connecting yarn 3a is connected and the chain knitting yarn 6m to which the connecting yarn 3b is connected. There are two or more. That is, the connecting yarns 3a and 3b are connected to the chain knitting yarn 6m at a constant interval. Accordingly, the knitting yarn 7 of the outer material 1 is supported by the connecting yarns 3a and 3b from the left and right. Since the lining 2 has a plain structure and is excellent in form stability, the knitting yarn 7 is supported from the left and right by the connecting yarns 3a and 3b extending from the lining 2 which is difficult to shift. Will be. As a result, the knitting yarn 7 has a structure that is difficult to shift from side to side.

  The structure of the double raschel knitted fabric used in the present invention has been described above. Next, the yarn constituting the knitted fabric will be described. The yarn constituting the outer material 1 is an original multifilament yarn kneaded with a weathering agent. A conventionally well-known thing can be employ | adopted as a weathering agent. Specifically, a UV absorber, an antioxidant, or a combination of both is used. As the ultraviolet absorber, benzotriazole compounds, benzophenone compounds, cyanoacrylate compounds, nickel compounds, copper compounds such as copper chloride and copper iodide, and the like can be used. In addition, a binderd amine compound can be used as the antioxidant. In the present invention, it is particularly preferable to use a copper-based compound, and it is most preferable to use copper iodide. The kneading of the weathering agent may be added at the time of polymerization of the polymer that is the raw material of the multifilament yarn, may be added to the polymer after polymerization, or added at the time of melt spinning the multifilament yarn. It may be exhausted when dyeing or refining the double raschel knitted fabric. In addition, any pigment can be used for the original, but since this double raschel knitted fabric is used at a golf driving range, it is preferable to use a green pigment for the original.

  The yarn constituting the lining 2 is also an original multifilament yarn kneaded with a weathering agent. The kind of weathering agent to be used, the method of kneading the weathering agent, the kind of the original material, and the like are the same as those of the outer material 1. The reason for using multifilament yarns for the outer material 1 and the lining material 2 is to impart flexibility to the outer material 1 and the lining material 2. When the outer material 1 is rigid, the cushioning property is lowered and it is difficult to walk. Further, if the lining 2 is rigid, it is difficult to follow the slope of the ground surface of the golf driving range, and it is difficult to automatically collect balls.

  The yarn constituting the connecting yarn 3 is an original monofilament yarn kneaded with a weathering agent. The kind of weathering agent, the method of kneading the weathering agent, and the kind of the original material are the same as those of the outer material 1 and the lining material 2. The difference between the outer material 1 and the lining 2 is that the original monofilament yarn is used as the yarn without using the original multifilament yarn. This is because if the thickness (fineness) of the multifilament yarn and the monofilament yarn are the same, the monofilament yarn has higher rigidity. That is, it is for increasing the rigidity of the connecting yarn 3 and making the structure of the surface material 1 difficult to shift.

  The connecting yarn 3 may be a single monofilament yarn, but preferably one in which two are aligned. This is because it is more rigid when two monofilament yarns are aligned than a single monofilament yarn. In addition, there may be two or more, but when there are many, such as five or more, the rigidity tends to decrease.

  In the ball collecting sheet according to the present invention, a surface material having a mesh-like structure having an approximately hexagonal or approximately rhombus-shaped watermark and a lining which is a plain structure are connected by a connecting thread. The connecting yarn is connected to the lining in a state in which the knitting yarn of the outer fabric is supported from the left-right direction. Therefore, even when a golf ball lands on the outer surface and an external force that shifts the outer surface is generated, the shape stability of the lining is good, and the connecting yarn supports the outer knitting yarn from the left and right directions. , The organization of the outer material is difficult to slip. Since the structure of the outer material is not easily displaced, even if the golf ball is landed, foreign matter such as sand is difficult to enter due to the displacement, and the yarn constituting the outer material is difficult to cut by the foreign material. In addition, a weathering agent is kneaded into the yarn constituting the ball collecting sheet according to the present invention. Therefore, even when exposed to sunlight or the like, deterioration with time is unlikely to occur, and the yarn is difficult to cut. Therefore, it is possible to prevent the outer surface from being damaged and the golf ball from being difficult to roll by cutting the yarn. Moreover, since the ball-collecting sheet according to the present invention is made of a double raschel knitted fabric using multifilament yarns as the yarns constituting the outer material and the lining material, the ball collecting sheet is excellent in cushioning and water permeability as in the prior art.

  Therefore, the ball-collecting sheet according to the present invention can be used in the same manner as before, and the golf ball can easily roll over a long period of time, and the number of laying of the ball-collecting sheet can be reduced.
