Description

Manufacturing method of screen fabric for screen golf and screen fabric produced thereby

[0001] The embodiments disclosed in this specification relate to a method for manufacturing a screen fabric to be installed in a screen golf course and a screen fabric produced thereby.

[0002] In recent years, as golf has become more popular, many people are visiting golf courses, and beginners or those who do not have much time are also frequently using golf practice ranges.

[0003] Among golf practice ranges, indoor screen golf ranges have golf simulation systems installed so that players can play golf as if they were playing on an actual golf course.

[0004] When a golfer hits a golf ball in a screen golf course implemented in this system, the hit golf ball hits the front screen and then falls, but the flight trajectory of the golf ball as it reaches the screen is detected by a flight detection means and is sent to the control unit, and the control unit uses the sent flight trajectory information to calculate the flight distance and stopping point of the golf ball, and then displays a 3D image along the flight path on the screen using a projector.

[0005] Typically, screen fabrics used in screen golf are primarily made from polyester fibers, a synthetic fiber. These synthetic fibers are non-recyclable and non-biodegradable, posing environmental risks and leading to high waste disposal costs.

[0006] As a related prior art, there is a screen for a golf simulator disclosed in Korean Patent Publication No. 10-1185705. However, since the screen of the above prior art is also made of synthetic fiber, there is a problem of causing environmental pollution when disposed of.

[0007] Accordingly, new technologies are required to overcome the limitations of the above prior art.

[0008] Meanwhile, the background technology described above is technical information that the inventor possessed for the purpose of deriving the present invention or acquired during the process of deriving the present invention, and cannot necessarily be said to be publicly known technology disclosed to the general public prior to the application for the present invention.

[0013] As a technical means for achieving the above-described technical task, a method for manufacturing a screen fabric for screen golf according to one embodiment is a method for manufacturing a screen fabric to be installed in a screen golf course, comprising the steps of: processing a biodegradable resin (PLA: Poly lactic acid) into yarn and weaving it to manufacture a fabric body having a predetermined area; and a coating step of applying a coating solution to at least one surface among both surfaces of the fabric body to form a coating layer, and forming at least one gap exposing the fabric body to the coating layer.

[0014] In addition, the coating step may include a step of forming a single row of coating layers by applying a coating solution containing polyurethane or silicone along at least one of the longitudinal direction and the width direction of the fabric body to a predetermined width; and a step of forming multiple rows of coating layers by repeatedly forming coating layers having the same width as the coating layer and spaced apart with a predetermined gap therebetween.

[0015] Additionally, the coating layer and the gap may each be formed with a width smaller than the maximum diameter of the golf ball.

[0016] Additionally, the coating layer and the gap may each be formed with a width such that at least two gaps can be placed within an area corresponding to the maximum diameter of the golf ball.

[0017] In addition, the coating step may include a step of forming a polygonal coating layer by applying a coating solution containing polyurethane or silicone in a polygonal shape to one surface of the fabric body; and a step of forming a gap in a polygonal shape between the polygonal coating layers while repeatedly forming the polygonal coating layer in the length direction and width direction of the fabric body.

[0018] Additionally, the polygonal coating layer and the gap may each be formed as a polygon having an area smaller than the maximum diameter of the golf ball.

[0019] Additionally, the polygonal coating layer and the gap may each be formed with an area in which at least two of the gaps can be placed within an area corresponding to the maximum diameter of the golf ball.

[0020] In addition, the step of manufacturing the fabric body may include a step of processing the biodegradable resin into long fibers and short fibers, respectively; a step of manufacturing yarn by processing the long fibers and short fibers; a step of weaving the yarn to make the fabric body; and a step of post-processing the woven fabric body.

[0021] In addition, the step of manufacturing the yarn may include a step of manufacturing a covering yarn by covering the long fibers and the short fibers; and a step of completing the yarn by twisting multiple strands of the covering yarn.

[0022] In addition, the step of weaving the above fabric body can weave the yarn into a plain weave or twill weave.

[0023] In addition, the post-processing step may include a step of refining the fabric body; a step of dyeing the refined fabric body; a step of flame-retarding the dyed fabric body; and a step of water-repellent processing the fabric body.

[0024] In addition, the manufacturing method may further include a step of performing CIRE processing by pressing the fabric body with a predetermined pressure through a roller at a predetermined temperature, prior to the coating step.

[0030] In addition, according to any one of the aforementioned problem solving means, a gap is formed in the coating layer to provide a space that can buffer the difference in elongation between the main body of the fabric and the coating layer, thereby suggesting a method for manufacturing a screen fabric that can reduce separation of the coating layer and damage to the main body of the fabric that may occur when impacted by a golf ball is applied.

[0041] Hereinafter, embodiments will be described in detail with reference to the attached drawings.

In addition, FIG. 3 is a process diagram showing a method for manufacturing a screen fabric according to one embodiment, FIG. 4 is a process diagram showing a fabric body according to one embodiment, FIG. 5 is a process diagram showing a coating step according to one embodiment, FIG. 6 is a configuration diagram showing the structure of a fabric body according to one embodiment, and FIGS. 7 to 9 are front views showing the configuration of screen fabrics according to other embodiments.

[0043] A screen fabric (10) for screen golf according to one embodiment is a member installed in a screen golf course to provide images of a golf simulation game while hitting a golf ball.

[0044] Referring to FIGS. 1 and 2, a screen fabric (10) according to one embodiment may be configured to include a fabric body (100) and a coating layer (200).

[0045] The above fabric body (100) forms the body of the screen fabric (10), and can be woven into a predetermined area by processing biodegradable resin (PLA: Poly lactic acid) into yarn and weaving it.

[0046] Here, biodegradable resin (PLA) is a biopolymer obtained through the fermentation process of lactic acid contained in natural materials such as corn and sugarcane, as is well known.

[0047] These biodegradable resins are made from ingredients extracted from natural sources and are therefore environmentally friendly, non-toxic, biodegradable, and biocompatible, making them a material for solving environmental pollution problems and an alternative to plastic materials.

[0048] The fabric body (100) is woven into a predetermined area using yarn processed from the biodegradable resin as described above, so it has the advantage of being environmentally friendly as it can be recycled or biodegraded by microorganisms when discarded.

[0049] The above coating layer (200) is a component for protecting the fabric body (100) by being formed by applying a coating liquid to at least one of the two sides of the fabric body (100).

[0050] It is preferable that this coating layer (200) be coated only on the front surface of the fabric body (100) where the golf ball is hit, but this is not limited to this, and it may be coated on both sides of the fabric body (100).

[0051] Here, the coating layer (200) is composed of a coating liquid containing at least one of polyurethane and silicone and can be coated on the fabric body (100) to a thickness of 2 to 4 mm.

[0052] Meanwhile, since the coating layer (200) has a different elongation, or degree of stretching, than the main body of the fabric (100), there is a risk that it may separate from the main body of the fabric (100) when struck by a golf ball.

[0053] In order to reduce the above phenomenon, a screen fabric (10) according to one embodiment can provide a space that can buffer the difference in stretching through a gap (300) while the coating layer (200) is formed in a stripe-shaped coating manner as shown in FIG. 1.

[0054] Specifically, the gap (300) is formed in the coating layer (200) to expose the fabric body (100) while dividing the coating layer (200) into a plurality of stripe shapes, thereby providing a space that can buffer the difference in elongation between the fabric body (100) and the coating layer (200) through the exposed portion of the fabric body (100).

[0055] Here, the coating layer (200) and the gap (300) divided into multiple parts by the gap (300) can be formed with a width smaller than the maximum diameter of the golf ball (1), as shown in FIG. 1.

[0056] In addition, the width of the coating layer (200) and the gap (300) divided into multiple parts by the gap (300) can be formed to a width that allows at least two gaps (300) to be positioned within an area corresponding to the maximum diameter of the golf ball (1).

[0057] For example, the coating layer (200) may be formed with a width of 15 to 20 mm, and the gap (300) may be formed with a width of 0.5 to 1 mm. Accordingly, at least two gaps (300) may be arranged within an area corresponding to the maximum diameter (42.87 mm) of the golf ball to provide a buffer space.

[0058] Meanwhile, the coating layer (200) may be repeatedly formed in the length direction and width direction of the fabric body (100) in a polygonal shape rather than a stripe shape as shown in FIGS. 7 to 9, and a gap (300) may be formed in a polygonal shape between the coating layers (200) forming the polygon to expose the fabric body (100).

[0059] Specifically, the coating layer (200) and the gap (300) can be formed in a triangular shape as shown in FIG. 7, can be formed in a square shape as shown in FIG. 8, and can be formed in a hexagonal and square shape as shown in FIG. 9, respectively.

[0060] Meanwhile, the coating layer (200) forming a polygon and the gap (300) of the polygon can be formed with an area smaller than the maximum diameter of the golf ball (1), as shown in FIGS. 7 to 9.

[0061] In addition, the area of ​​the polygonal coating layer (200) and the polygonal gap (300) can each be formed as an area in which at least two gaps (300) can be located within an area corresponding to the maximum diameter of the golf ball (1).

[0062] The polygonal coating layer (200) and gap (300) can reduce cracks in the coating surface caused by impact when a golf ball (1) is hit and maintain the tensile strength of the fabric body (100). Unlike a circular golf ball (1), the polygonal shape can be expected to have the effect of maintaining the coating strength (adhesion).

[0063] Hereinafter, a method for manufacturing a screen fabric (10) according to one embodiment will be described with reference to FIGS. 2 to 5.

[0064] A method for manufacturing a screen fabric according to one embodiment may be performed including a step of manufacturing a fabric body (S100), a step of processing a CIRE (Cire) (S200), and a coating step (S300).

[0065] The step of manufacturing the fabric body (S100) is a process of manufacturing the fabric body (100) described above, and can be performed including a processing step (S110), a yarn manufacturing step (S120), a fabric body manufacturing step (S130), and a post-processing step (S140), as shown in FIG. 4.

[0066] The processing step (S110) is a process for processing the biodegradable resin into fibers, and the biodegradable resin can be processed into short fibers and long fibers, respectively.

[0067] As is known, staple fibers are made by spinning or twisting a collection of short fibers, and their thickness is expressed in units of count (count), while long fibers are made by making long fibers into a single thread, and their thickness is expressed in units of denier.

[0068] Specifically, in the processing step (S110), the biodegradable resin raw material is melted and extruded, and then long fibers and short fibers can be created through stretching, clamping, and cutting processes.

[0069] The step of manufacturing yarn (S120) is a step of manufacturing yarn by twisting long fibers and short fibers. Specifically, a covering yarn is manufactured through a covering process in which long fibers are rolled around short fibers, and then a twisting process in which multiple strands of the covering yarn are twisted is performed to manufacture yarn.

[0070] Here, in the step of manufacturing yarn (S120), yarn can be manufactured using, for example, long fibers of 250 to 500 denier and short fibers of 10 to 40 counts, and the tensile and bursting strength of the yarn can be adjusted through two- or three-ply twisting.

[0071] The step of weaving the fabric body (S130) is a process of weaving yarns into warp and weft yarns to create a fabric body (100) with a predetermined area, and the fabric body (100) can be woven by weaving the yarns into a plain weave or twill weave.

[0072] Plain weave, as is known, is a weaving method in which the warp and weft yarns are alternately crossed one by one, while twill weave is a weaving method in which the number of warp and weft yarns crossing each other is different.

[0073] For example, in the step of weaving the main body of the fabric (S130), it can be woven into a twill structure with the number of intersecting wefts and warps being 1 / 2 to 1 / 5.

[0074] Accordingly, the fabric body (100) can form a diagonal pattern of yarns as shown in FIG. 6.

[0075] The post-processing step (S140) is a step of completing the woven fabric body (100) by post-processing.

[0076] Specifically, the post-processing step (S140) may be performed to perform a refining process to remove impurities from the fabric body (100), after which the fabric body may be dyed, and after the dyed fabric body is flame-retardant treated, a water-repellent treatment may be performed to lower the moisture absorption rate of the fabric body (100), thereby completing the fabric body (100).

[0077] The above CIRE processing step (S200) is a process for increasing the resolution of the post-processed fabric body (100) tissue, and can be performed by pressing the fabric body (100) with a predetermined pressure through a roller at a predetermined temperature.

[0078] For example, in the CIRE processing step (S200), the tissue resolution of the fabric body (100) can be increased by pressing the fabric body (100) with a roller pressure of 30 to 60 tons at a temperature of 180 to 240 degrees.

[0079] The above coating step (S300) is a process of forming the aforementioned coating layer (200) by applying a coating solution to at least one of both sides of the fabric body (100) and forming the aforementioned gap (300) in the coating layer (200).

[0080] This coating step (S300) can coat the fabric body (100) with a coating solution containing at least one of polyurethane and silicone to a thickness of 2 to 4 mm as described above, and the coating method can be applied by a knife method or a foaming method, and in addition, any method of coating the coating solution on the fabric can be applied.

[0081] Specifically, the coating step (S300) forms a single row of coating layers by applying a coating solution along at least one of the longitudinal direction or the width direction of the fabric body (100) to a predetermined width as illustrated in FIG. 5 (S310), and then repeatedly forming a plurality of coating layers (200) having the same width as the coating layer in multiple rows while being spaced apart from each other by the aforementioned gap (300) (S320), thereby forming the coating layers (200) in a stripe shape.

[0082] Meanwhile, the coating step (S300) may form a polygonal coating layer by applying a coating liquid to the fabric body (100) in a polygonal shape, and then repeatedly forming the polygonal coating layer in the length direction and width direction of the fabric body (100) to form a gap (300) in a polygonal shape between the coating layers (200).

[0083] Accordingly, the coating layer (200) can be formed in a form divided into multiple rows by gaps (300), and a space that can buffer the difference in elongation between the main body (100) and the coating layer (200) can be provided through the gaps (300).

[0084] As described above, the method for manufacturing a screen fabric according to one embodiment and the screen fabric (10) thereby manufactured are manufactured by processing a biodegradable resin into yarn and weaving it, so that the screen fabric (10) can be recycled or biodegraded when discarded, making it environmentally friendly and reducing disposal costs. In addition, a gap (300) is formed in the coating layer (200) to provide a space that can cushion the difference in elongation between the fabric body (100) and the coating layer (200), thereby reducing the separation of the coating layer (200) and the damage to the fabric body (100) that may occur when impacted by a golf ball is applied.

[0085] The embodiments described above are provided for illustrative purposes only, and those skilled in the art will readily appreciate that the embodiments described above can be readily modified into other specific forms without altering the technical concepts or essential characteristics of the embodiments described above. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, components described as being single may be implemented in a distributed manner, and similarly, components described as being distributed may be implemented in a combined manner.
