Description

[Detailed description of the invention] Industrial applications The present invention relates to a rug and a method of manufacturing the rug.

Conventional technology and its problems In a golf ball batting range, the landing point of the hit golf ball is a gentle slope, and the golf balls rolling along the slope are collected at a predetermined position and collected. It is supposed to be done.

In conventional golf ball hitting practice ranges, the slope was hard, so the falling balls bounced a lot, making it impossible to get a feeling similar to playing on an actual golf course.

In order to suppress the bouncing of the golf ball when it falls, it is conceivable to lay on the slope a mat such as artificial grass, which is provided with cushioning properties using cut piles or loop piles. However, the cut pile or loop pile on the surface of the rug deteriorates the degree of rolling of the golf ball and tends to stop the ball midway down the slope. Therefore, in order to ensure the ball collecting function using the slope, the slope of the slope must be increased,
There was a problem that the labor and cost of construction increased.

The above-mentioned slope at a general golf ball batting practice range is
In order to avoid such problems, needle-punched nonwoven fabrics and the like are laid. However, the above nonwoven fabrics, etc.
Since extremely thin fibers are punched, the fibers are easily pulled out due to friction or impact when the golf ball falls, and there is a problem in that the fibers adhere to the ball and stain the golf ball.

An object of the present invention is to solve the above-mentioned problems, to be able to suppress the amount of bouncing of golf balls on slopes of ball collection equipment, and to ensure the rolling of golf balls even on slopes with small slopes. An object of the present invention is to provide a rug that can prevent or reduce stains on golf balls and a method for manufacturing the same.

Means for Solving the Problems The above object of the present invention is to provide a base fabric having a fibrous web layer on its surface, a base fabric having a large number of loop piles planted in rows,
The loop pile is achieved by a rug characterized in that it is connected in a chain by sequentially planting one loop through the next.

The fiber web layer preferably has a single fiber fineness of 3 denier to 80 denier.

Further, the above object of the present invention is to pierce the needle holding the pile yarn from the back side of the base fabric and move it up and down, and to form the pile yarn into a loop in conjunction with the forward and backward movement of the louver.
A method for manufacturing a rug, in which the operation of inserting the needle into the loop to form the next loop pile is continuously repeated, and a loop pile in which the loops are connected in a chain is formed on the surface of the base fabric. The present invention is also achieved by a method for producing a rug, characterized in that the base fabric is provided with a fiber web layer on its surface.

placing a web formed by intertwining fibers on the base fabric;
By piercing a plurality of points from above with a needle, a part of the web is made to protrude to the back side of the base fabric, and the web is bonded to the base fabric, thereby forming the fibrous web layer on the surface of the base fabric. You may.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2 show a rug according to the 1' embodiment of the invention. This rug has a large number of loop piles (3) formed on the surface of a base fabric (2) based on the planting of pile yarns (1), and a fibrous web layer (3) on the surface of the base fabric (2). 4)
is provided.

The loop pile (3) has its loops connected in a chain shape along the planting direction of the pile yarn (1) with respect to the base fabric (2), and one of the adjacent loop piles (3) is connected to the fiber web layer. (4) and press the other loop pile (
3), the fiber web layer (4) is pressed into a collapsed state and given elasticity, and the adjacent loop piles (
3) is sewn to the base fabric (2) so as to prevent each other from being removed. In order to further prevent the plurality of loop piles (3) from coming off, a resin layer (5) is provided on the back surface of the base fabric (2) by backing treatment. Base fabric (2
) To provide the fibrous web layer (4) on the base fabric (2), for example, a web formed by intertwining fibers is placed on the base fabric (2), and a needle is pierced through the base fabric (2) in many places to form part of the web as the base fabric. It is possible to adopt a joining method of protruding to the back side of the fabric (2), that is, needle locking, or to connect the base fabric (2) with thread.
2) It is also possible to adopt a sewing method in which a web is sewn on top. A pile yarn (1) is planted on a base fabric (2) provided with a fiber web layer (4), and a large number of loop piles (3) are formed.
form. Based on the planting of the pile yarn (1), the base fabric (2
) and the fibrous web layer (4) are firmly fixed, the initial bonding of these base fabric (2) and web layer (4) does not have to be strong, and therefore the above bonding and sewing methods Other appropriate methods can also be adopted. When using a bonding method based on needle locking, base fabric (2)
Since the resin 5 for preventing slipping out is bonded to the web protruding from the back side, a uniform resin layer (5) is not formed on the back side of the base fabric (2) and is not coated on the entire back side. Good water permeability can be imparted, and the amount of the resin used can be controlled.

This is particularly effective when the base fabric (2) is made of a polypropylene resin or the like that does not have good bonding properties with the resin.

The rug configured in this manner is placed on a slope of a ball collection facility provided at a golf ball batting practice range and is appropriately fixed.

In this rug, the surface of the base fabric (2) is the fiber web layer (4).
), and is further laid down to provide elasticity, a large number of loop piles (3) are formed, so that the impact caused by a direct hit from a golf ball is applied to the loop piles (3) and the fiber web layer (4). ), which has the advantage of suppressing the amount of bounce of the golf ball. In addition, a large number of loop piles (3) that firmly bond the fiber web layer (4) to the base fabric (2) are attached to the base fabric (2).
4) Since the single fibers of the fiber web layer (4) are formed on top of the golf ball, it is difficult for the single fibers of the fiber web layer (4) to come into direct contact with the golf ball, and it is difficult for them to receive friction, impact, etc. when the golf ball falls. Therefore,
It is possible to prevent single fibers from coming off due to a direct hit with a golf ball, and to eliminate or reduce the problem of the single fibers staining the golf ball. Furthermore, since the surface of the base fabric (2) is covered with the fiber web layer (4) as described above, the base fabric (2) is difficult to receive direct sunlight that accelerates its deterioration, and therefore has poor weather resistance. It also has the advantage of being excellent. Moreover, based on the above-described good water permeability of the base fabric (2), rainwater during rainy weather can be drained from the back surface of the base fabric (2).

As the single yarn forming the fiber web layer (4), it is preferable to use one having a fineness of 3 denier to 80 denier,
More preferably, the fineness is 10 denier to 60 denier. If the single yarns have a denier of less than 3, appropriate rigidity cannot be imparted to the intertwined single yarns, and therefore, the above-mentioned impact mitigation performance cannot be achieved sufficiently. In addition, single yarns with a fineness exceeding 80 denier have too large needle resistance when they are planted on the base fabric (2)' and when the pile yarn (1) is planted on the base fabric (2). It is difficult to manufacture, and it cannot be entwined well with the base fabric (2), resulting in a lack of a sense of unity.

When manufacturing the loop pile (3) in which loops are connected in a chain, the louvers (6) shown in FIGS. 3A and 3B are used.
) is used. The louver (6) consists of a substantially rectangular plate (61) extending vertically, and a first claw piece (62) extending from the upper end of the plate (61) to one side in the width direction; The first one is fixed to the other side in the width direction at the upper end of the plate (61).
It has a second claw piece (63) that extends parallel to the claw piece (62) side and partially overlaps the first claw piece (62). The second
The claw piece (63) has elasticity, and as shown in FIG. 3A,
Its fixed side is once bent toward the side away from the plate (61), and its tip end is the first claw piece (
62). Therefore, the second claw piece (63) is separated from the first claw piece (62) by a gap (64).

Below, a method for producing a chain-connected loop pile (3) using the louver (6) will be described.

First, a base fabric (2) having a fiber web layer (4) on its surface is prepared.

Pierce it from the back side of 2) and move it downward, then attach the base fabric (2)
The louver (6) arranged on the lower side of the louver (6) is rotated forward (see Fig. 4 (a)), and the first and second claw pieces (62), (63

reference). Next, the needle (7) is moved upward and the pile thread (1) is pulled out from the base fabric (2) while being hooked to both claw pieces (62) and (63) (Fig. 4 (C) )reference). Then, immediately pierce the base fabric (2) with the needle (7),
It is further lowered to insert the needle (7) into the gap (64) of the louver (6) (see FIG. 4(d)). At this time, the louver (6) is in a backward rotating state, and by further retreating the louver (6), the needle (7) pushes and spreads the tip of the second elastic claw piece (63). 4

, both claw pieces (62).

Pile yarn (1) with (63) held by needle (7)
is hooked, resulting in the state shown in FIG. 4(b). In this way, the pile yarn (1) is formed into a loop by the vertical movement of the needle (7) holding the pile yarn (1) and the forward and backward movement of the louver (6), and the needle ( 7)
can be inserted to form the next loop pile (3).

By continuously repeating this operation, a loop pile (3) in which loops are connected in a chain can be formed on the surface of the base fabric (2).

Effects of the Invention As is clear from the above, in the rug of the present invention, a fiber web layer is provided on the surface of the base fabric of the loop pile in which loops are connected in a chain. As a result, the amount of bouncing of golf balls on the slope of the ball collecting equipment can be suppressed. Furthermore, since the loops of the loop pile are connected in a chain, the loop pile is brought into a collapsed state, and the rolling of the golf ball can therefore be ensured even on a slope with a small slope. In addition, in the rug of the present invention, since a large number of loop piles are formed on the fiber web layer, direct contact between the fiber web layer and the golf ball can be reduced. Contamination of the ball can be prevented or reduced.

In the manufacturing method of the present invention, a needle holding a pile yarn is pierced through the back side of a base fabric having a fibrous web layer on the surface and moved up and down, and the pile yarn is formed into a loop in conjunction with the forward and backward movement of the louver. The operation of inserting a needle into the loop and forming the next loop pile is continuously repeated to form a loop pile in which the loops are connected in a chain on the surface of the base fabric, thereby producing a rug with the above effects. can do.
