Description

Technical Field

[0001] The embodiments disclosed in this specification relate to a method for manufacturing a screen fabric for use in a screen golf course, and the screen fabric obtained therefrom. Background Technology

[0002] In recent years, with the popularization of golf, more and more people are going to golf courses, and golf driving ranges are also frequently used by beginners or people with limited time.

[0003] The golf driving range features an indoor screen golf course equipped with a golf simulation system, allowing participants to play golf as if they were on a real golf course.

[0004] In this screen-based golf course system, when a golfer hits a golf ball, the ball first strikes the front screen before falling. However, as it reaches the screen, the ball's trajectory is detected by a flight detection device and transmitted to the control unit. The control unit uses the transmitted trajectory information to calculate the ball's flight distance and stopping point, and then displays a 3D image generated along the flight path on the screen via a projector.

[0005] Generally, the screen fabric used in in-screen golf is mainly made of synthetic fibers, namely polyester yarn. Screen fabrics made from these synthetic fibers are non-recyclable and non-biodegradable, thus posing environmental hazards and resulting in high waste disposal costs.

[0006] As a related prior art, although Korean Patent Publication No. 10-1185705 discloses a screen for a golf simulator, the screen of the prior art, as described above, is also made of synthetic fiber yarn, which poses a problem of environmental pollution when it is discarded.

[0046] According to one embodiment, the screen fabric 10 for screen golf is a component installed on a screen golf course and subjected to the impact of a golf ball while providing images of a golf simulation game.

[0047] Reference Figure 1 and Figure 2 According to one embodiment, the screen fabric 10 may include a fabric substrate 100 and a coating 200.

[0048] The fabric substrate 100 constitutes the main body of the screen fabric 10. It can be made by processing biodegradable resin (polylactic acid (PLA)) into raw yarn and weaving it to form a specified area.

[0049] Biodegradable resin (PLA), as is known, is a biopolymer produced by fermentation of lactic acid contained in natural materials such as corn and sugarcane.

[0050] Because this biodegradable resin is made from components extracted from natural sources, it is environmentally friendly and has excellent non-toxicity, biodegradability, and biocompatibility, making it suitable as a material for solving environmental pollution problems and as an alternative to plastic materials.

[0051] The fabric substrate 100 is woven by using raw yarn processed from the biodegradable resin described above to weave a specified area, so it can be recycled or biodegraded by microorganisms when discarded, thus having environmental advantages.

[0052] The coating 200 is formed by applying a coating liquid to at least one of the two sides of the fabric substrate 100, and is a component for protecting the fabric substrate 100.

[0053] This coating 200 is preferably applied only to the front surface of the fabric substrate 100 that is subjected to golf ball impacts, but it is not limited thereto and may also be applied to both sides of the fabric substrate 100.

[0054] The coating 200 is composed of a coating liquid containing at least one of polyurethane and silicone, and can be applied to the fabric substrate 100 with a thickness of 2 to 4 mm.

[0055] On the other hand, since the coating 200 and the fabric substrate 100 have different elongation rates (i.e., elongation), the coating 200 may separate from the fabric substrate 100 when it is hit by a golf ball.

[0056] To reduce the phenomena described above, such as Figure 1 As shown, in a screen fabric 10 according to one embodiment, the coating 200 is formed in a striped pattern and provides space through gaps 300 to buffer elongation differences.

[0057] Specifically, the gap 300 is formed in the coating 200 to divide the coating 200 into multiple rows of stripe shapes and expose the fabric substrate 100, thereby providing space through the exposed portion of the fabric substrate 100 that can buffer the elongation difference between the fabric substrate 100 and the coating 200.

[0058] Among them, such as Figure 1 As shown, the coating 200 and the gap 300, which are divided into multiple columns by the gap 300, can be formed to have a width smaller than the maximum diameter of the golf ball 1.

[0059] Furthermore, the width of the coating 200 divided into multiple columns by the gap 300 and the width of the gap 300 can be respectively formed such that at least two gaps 300 can be arranged in the area corresponding to the maximum diameter of the golf ball 1.

[0060] For example, the width of coating 200 can be 15–20 mm, and the width of gap 300 can be 0.5–1 mm. Thus, at least two gaps 300 can be configured in an area corresponding to the maximum diameter of a golf ball (42.87 mm) to provide buffer space.

[0061] On the other hand, such as Figures 7 to 9 As shown, the coating 200 can be in the form of a non-striped polygonal shape, repeatedly formed along the length and width directions of the fabric substrate 100, and the gaps 300 can be formed in a polygonal form between the coatings 200 constituting the polygon to expose the fabric substrate 100.

[0062] Specifically, such as Figure 7 As shown, the coating 200 and the gap 300 can each be triangular in shape, such as... Figure 8 As shown, they can also be in quadrilateral form, such as Figure 9 As shown, they can also be in hexagonal and quadrilateral form respectively.

[0063] On the other hand, such as Figures 7 to 9 As shown, the areas of the polygonal coating 200 and the polygonal gap 300 can be formed to be smaller than the maximum diameter of the golf ball 1.

[0064] Furthermore, the area of ​​the polygonal coating 200 and the area of ​​the polygonal gap 300 can be respectively formed such that at least two gaps 300 can be arranged in the area corresponding to the maximum diameter of the golf ball 1.

[0065] The polygonal coating 200 and gaps 300 can reduce cracking of the coating surface caused by the impact of the golf ball 1 when it is hit, and maintain the tension of the fabric substrate 100. Unlike the round golf ball 1, it is formed in a polygonal shape, so it can be expected to maintain the coating firmness (adhesion).

[0066] The following will refer to Figures 2 to 5 A method for manufacturing screen fabric 10 according to one embodiment is described.

[0067] A method for manufacturing a screen fabric according to one embodiment may include: a step of manufacturing a fabric substrate (S100), a step of performing a calendering (CIRE) process (S200), and a coating step (S300).

[0068] The step of manufacturing the fabric substrate (S100) is the process of manufacturing the aforementioned fabric substrate 100, such as... Figure 4 As shown, it includes: a processing step (S110), a step of manufacturing raw yarn (S120), a step of making fabric substrate (S130), and a post-processing step (S140).

[0069] The processing step (S110) is a process for processing biodegradable resin into fibers, which can be processed into short fibers and long fibers.

[0070] As is known, short fibers are made by spinning or twisting an aggregate of short fibers, and their thickness is expressed in count. Long fibers are a thread made of long fibers, and their thickness is expressed in denier.

[0071] Specifically, in the processing step (S110), the biodegradable resin raw material can be melt-extruded and then processed into long fibers and short fibers by stretching, clamping and cutting.

[0072] The step of manufacturing the raw yarn (S120) is to spin long fibers and short fibers to manufacture the raw yarn. Specifically, the raw yarn can be manufactured by wrapping the long fibers around the short fibers in a winding form, and then by twisting the multiple strands of the wrapped raw yarn together.

[0073] In the step of manufacturing the raw yarn (S120), for example, long fibers with a denier of 250 to 500 and short fibers with a count of 10 to 40 can be used to manufacture the raw yarn, and the tensile and breaking strength of the raw yarn can be adjusted by plying 2 to 3 strands.

[0074] The step of weaving the fabric substrate (S130) is a process of weaving the raw yarn with warp and weft yarns to form the fabric substrate 100 with a specified area. The fabric substrate 100 can be woven by weaving the raw yarn with plain weave or twill weave.

[0075] Plain weave, as is known, is a method of weaving where warp and weft yarns are woven alternately one by one. Twill weave (twill method) refers to a method of weaving where the number of intersections between warp and weft yarns is different.

[0076] For example, in the step of weaving the fabric substrate (S130), the number of intersecting weft yarns and warp yarns can be set to 1 / 2 to 1 / 5 to be woven in a twill weave.

[0077] Therefore, as Figure 6 As shown, the raw yarn of the fabric substrate 100 can form a twill pattern.

[0078] The post-processing step (S140) is a step that involves post-processing the woven fabric substrate 100.

[0079] Specifically, in the post-processing step (S140), a refining process to remove impurities from the fabric substrate 100 can be performed, followed by dyeing of the fabric substrate, flame retardant treatment of the dyed fabric substrate, and then waterproofing treatment to reduce the moisture absorption rate of the fabric substrate 100, thereby completing the fabric substrate 100.

[0080] The calendering process (S200) is a process to improve the resolution of the fabric substrate 100 for subsequent processing. It can be performed by pressing the fabric substrate 100 with a specified pressure through a roller at a specified temperature.

[0081] For example, in the calendering process (S200), the fabric substrate 100 is pressurized at a temperature of 180 to 240 degrees Celsius with a roller pressure of 30 to 60 tons, thereby improving the fabric substrate 100's structure resolution.

[0082] The coating step (S300) is a process of applying a coating liquid to at least one of the two sides of the fabric substrate 100 to form the aforementioned coating 200 and to form the aforementioned gap 300 in the coating 200.

[0083] As mentioned above, the coating step (S300) can coat the fabric substrate 100 with a coating liquid containing at least one of polyurethane and silicone to a thickness of 2 to 4 mm. The coating method can be a scraper method or a foaming method, etc. In addition, all methods that can be used to coat the coating liquid onto the fabric are applicable.

[0084] Specifically, such as Figure 5 As shown, in the coating step (S300), the coating liquid can be applied along at least one of the length direction and the width direction of the fabric substrate 100 to form a column of coating (S310), and then multiple columns of coating 200 with the same width as the coating are formed. The coating 200 is repeatedly formed in such a way that the aforementioned gap 300 is provided between each column of coating (S320), so that the coating 200 can be striped.

[0085] On the other hand, in the coating step (S300), the coating liquid can be coated on the fabric substrate 100 in a polygonal form to form a polygonal coating, and then the polygonal coating can be repeatedly formed along the length and width directions of the fabric substrate 100, and polygonal gaps 300 are formed between the coatings 200.

[0086] Thus, the coating 200 can be divided into multiple rows by the gap 300, and the gap 300 can provide space to buffer the elongation difference between the fabric substrate 100 and the coating 200.

[0087] As described above, according to an embodiment of the screen fabric manufacturing method and the screen fabric 10 obtained therefrom, the fabric substrate 100 is manufactured by processing biodegradable resin into raw yarn and weaving it. Therefore, when the screen fabric 10 is discarded, it can be recycled or biodegraded, which is environmentally friendly and can reduce waste costs. Furthermore, since gaps 300 are formed in the coating 200, space is provided to buffer the elongation difference between the fabric substrate 100 and the coating 200. Therefore, the separation of the coating 200 and the damage to the fabric substrate 100 that may occur due to the impact of a golf ball can be reduced.

[0088] The above embodiments are merely illustrative, and those skilled in the art should understand that they can be easily modified into other specific forms without changing the technical concept or essential features of the above embodiments. Therefore, it should be understood that the above embodiments are exemplary in all respects and not limiting. For example, the constituent elements described in a single form can also be implemented separately, and similarly, the constituent elements described in a separate form can also be implemented in a combined form.
