Description

Technical Field

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

Background Art

[0002] Recently, with the popularization of golf, a large number of people are looking for golf courses, and beginners and people with insufficient time often use golf driving ranges.

[0003] Among golf driving ranges, in a screen golf course installed indoors, a golf simulation system is installed so that golf competitions can be held as if actually enjoying golf on a golf course.

[0004] When a golfer hits a golf ball in a screen golf course implemented by such a system, the hit golf ball hits the front screen and then falls, but the flight trajectory of the golf ball in the process until it reaches the screen is sensed by flight sensing means and applied to the control unit. The control unit calculates the flight distance and stop point of the golf ball using the applied flight trajectory information, and then displays a three-dimensional image advancing along the flight path on the screen via a projector.

[0005] Generally, as the screen fabric used for screen golf, a fabric manufactured from polyester raw yarn, which is mainly a synthetic fiber, is mainly used. Such a screen fabric made of synthetic fiber is non-recyclable and non-biodegradable, so there are problems harmful to the environment and the waste treatment cost is also high.

[0006] As a related prior art, there is a screen for a golf simulator disclosed in Korean Patent Publication No. 10-1185705. However, since such a prior art screen is also manufactured from synthetic fiber yarns, there is a problem of causing environmental pollution during disposal.

[0007] Therefore, new technologies are needed to overcome the limitations of the prior art described above.

[0008] On the other hand, the aforementioned background technology is technical information that the inventor possesses for the purpose of deriving the present invention, or that was acquired during the process of deriving the present invention, and is not necessarily publicly known technology that was made public before the filing of the present invention.

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

[0016] Furthermore, each of the coating layer and the gap may be formed with a width such that at least two of the gaps are located within a region corresponding to the maximum diameter of the golf ball.

[0021] Furthermore, the steps for manufacturing the yarn may include the steps of covering the long fibers and short fibers to manufacture a covering yarn, and twisting a plurality of the covering yarns to complete the yarn.

[0022] Furthermore, in the stage of weaving the main body of the fabric, the raw yarn can be woven into a plain weave or twill weave structure.

[0037] One embodiment of the screen golf screen fabric 10 is installed on a screen golf course and is a component that provides images for a golf simulation game and simulates the impact of hitting a golf ball.

[0038] Referring to Figures 1 and 2, the screen fabric 10 according to one embodiment may include a fabric body 100 and a coating layer 200.

[0039] The aforementioned fabric body 100 forms the core of the screen fabric 10, and can be woven by processing a biodegradable resin (PLA: Polylactic acid) into yarn to have a predetermined area.

[0040] Here, as is well known, biodegradable resin (PLA) is a biopolymer obtained through the fermentation process of lactic acid contained in natural materials such as corn and sugarcane.

[0041] Because these biodegradable resins are manufactured from components extracted from natural materials, they are environmentally friendly, non-toxic, and possess excellent biodegradability and bioexchangeability. They are used as a solution to environmental pollution problems while also serving as an alternative to plastic materials.

[0042] The fabric body 100 is woven using yarn processed from the biodegradable resin described above to have a predetermined area, and therefore has the advantage of being environmentally friendly as it can be recycled or biodegraded by microorganisms when discarded.

[0043] The coating layer 200 is formed by applying a coating liquid to at least one of the two surfaces of the fabric body 100, and is a component for protecting the fabric body 100.

[0044] Preferably, such a coating layer 200 is coated only on the front surface of the fabric body 100 that is struck by the golf ball, but it is not limited to this, and can also be coated on both sides of the fabric body 100.

[0045] Here, the coating layer 200 is composed of a coating liquid containing at least one of polyurethane and silicone, and can be coated onto the fabric body 100 to a thickness of 2 to 4 mm.

[0046] On the other hand, because the coating layer 200 has a different elongation rate, i.e., a different degree of stretching, than the main fabric 100, there is a risk that it may separate from the main fabric 100 when struck by a golf ball.

[0047] To reduce the phenomena described above, in one embodiment, the screen fabric 10, as shown in Figure 1, has a coating layer 200 formed in a striped coating manner, which provides a space that can compensate for the difference in elongation rate through the gap 300.

[0048] Specifically, the gap 300 is formed in the coating layer 200, dividing the coating layer 200 into multiple stripe-like rows and exposing the fabric body 100. This provides a space where the exposed portion of the fabric body 100 can compensate for the difference in elongation between the fabric body 100 and the coating layer 200.

[0049] Here, each of the gaps 300 and the coating layers 200 divided by the gaps 300 may be formed with a width smaller than the maximum diameter of the golf ball 1, as shown in Figure 1.

[0050] Furthermore, the widths of the gaps 300 and the coating layers 200 divided into multiple sections by the gaps 300 can be formed such that at least two gaps 300 can be located within a region corresponding to the maximum diameter of the golf ball 1.

[0051] For example, the coating layer 200 may be formed to a width of 15 to 20 mm, and the gap 300 may be formed to a width of 0.5 to 1 mm. Thus, at least two gaps 300 can be placed within a region corresponding to the maximum diameter of a golf ball (42.87 mm) to provide a buffer space.

[0052] On the other hand, as shown in Figures 7 to 9, the coating layer 200 is polygonal rather than striped, and is repeatedly formed in the longitudinal and width directions of the fabric body 100. The gap 300 is formed in a polygonal shape between the polygonal coating layer 200, allowing the fabric body 100 to be exposed.

[0053] Specifically, the coating layer 200 and the gap 300 may be formed in a triangular shape as shown in Figure 7, in a square shape as shown in Figure 8, or in a hexagonal and square shape as shown in Figure 9.

[0054] On the other hand, each of the polygonal coating layer 200 and the polygonal gap 300 can be formed in an area smaller than the maximum diameter of the golf ball 1, as shown in Figures 7 to 9.

[0055] Furthermore, the area of ​​the polygonal coating layer 200 and the polygonal gap 300 can be formed in an area where at least two gaps 300 are located within the region corresponding to the maximum diameter of the golf ball 1.

[0056] The polygonal coating layer 200 and gap 300 reduce cracking of the coating surface due to impact when the golf ball 1 is struck, and maintain the tensile strength of the main body 100. Unlike the circular golf ball 1, the polygonal shape is expected to maintain the coating's durability (adhesion).

[0057] The following describes a method for manufacturing screen fabric 10 according to one embodiment, with reference to Figures 2 to 5.

[0058] A method for manufacturing screen fabric according to one embodiment may include a step of manufacturing the fabric body (S100), a step of applying a cire (S200), and a coating step (S300).

[0059] The stage of manufacturing the main fabric (S100) is the process of manufacturing the main fabric 100 as described above, and as shown in Figure 4, it may include a processing stage (S110), a stage of manufacturing the raw yarn (S120), a stage of manufacturing the main fabric (S130), and a post-processing stage (S140).

[0060] The processing stage (S110) is a process of processing the biodegradable resin into fibers, and the biodegradable resin can be processed into short fibers and long fibers, respectively.

[0061] As is well known, staple fibers are produced by spinning or twisting a collection of short fibers, and their thickness is expressed in units of count (yarn count), while filament fibers are produced by spinning long fibers into a single thread, and their thickness is expressed in units of denier.

[0062] Specifically, in the processing stage (S110), after melting and extruding the biodegradable resin raw material, long fibers and short fibers can be produced by stretching, clamping, and cutting.

[0063] The stage of manufacturing the raw yarn (S120) is a stage in which long fibers and short fibers are processed into yarn to manufacture the raw yarn. Specifically, after manufacturing covering raw yarn by a covering process in which long fibers are wound around short fibers, the raw yarn can be manufactured by a twisting process in which multiple covering raw yarns are twisted together.

[0064] In the stage of manufacturing the raw yarn (S120), for example, the raw yarn can be manufactured using long fibers of 250 to 500 denier and short fibers of 10 to 40 counts, and the tensile strength and bursting strength of the raw yarn can be adjusted by 2-ply and 3-ply twisting processes.

[0065] The stage of weaving the main body of the fabric (S130) is a process of weaving the raw yarn into warp and weft threads to produce a main body of fabric 100 of a predetermined area. The main body of the fabric 100 can be woven by weaving the raw yarn into a plain weave or twill weave.

[0066] As is well known, plain weave is a method of weaving in which warp and weft threads are interwoven one by one alternately, while twill weave is a method of weaving in which the number of warp and weft threads intersecting is different.

[0067] For example, in the stage of weaving the main body of the fabric (S130), it is possible to weave a twill weave structure in which the number of intersecting weft and warp threads is 1 / 2 to 1 / 5.

[0068] Therefore, as shown in Figure 6, the fabric body 100 can form a diagonal pattern with its yarn.

[0069] The post-processing stage (S140) is the stage in which the woven fabric body 100 is post-processed to complete the product.

[0070] Specifically, in the post-processing stage (S140), after performing a scouring process to remove impurities from the fabric body 100, the fabric body can be dyed, and after the dyed fabric body is flame-retardant treated, a water-repellent treatment is performed to reduce the moisture absorption rate of the fabric body 100 to complete the fabric body 100.

[0071] The aforementioned cire (CIRE) processing step (S200) is a process to improve the resolution of the post-processed fabric body 100, and can be performed by pressing the fabric body 100 with a roller at a predetermined pressure at a predetermined temperature.

[0072] For example, in the CIRE processing stage (S200), the fabric body 100 can be pressed with a roller pressure of 30 to 60 tons at a temperature of 180 to 240 degrees Celsius, thereby increasing the weave resolution of the fabric body 100.

[0073] The coating step (S300) is a step in which a coating liquid is applied to at least one of the two surfaces of the fabric body 100 to form the aforementioned coating layer 200, while simultaneously forming the aforementioned gap 300 in the coating layer 200.

[0074] As mentioned above, this coating step (S300) allows for coating the fabric body 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 knife method, a foaming method, or any other method of coating the fabric with the coating liquid.

[0075] Specifically, in the coating step (S300), as shown in Figure 5, the coating liquid is applied to the fabric body 100 along at least one of the longitudinal and width directions to form a single layer of coating (S310). Then, in forming multiple layers of coating 200 having the same width as this layer, the coating layers 200 are repeatedly formed so as to be separated by the aforementioned gap 300 (S320), thereby forming the coating layers 200 in a striped pattern.

[0076] On the other hand, in the coating stage (S300), the coating liquid can be applied to the fabric body 100 in a polygonal shape to form one polygonal coating layer, and then the polygonal coating layer can be repeatedly formed in the longitudinal and width directions of the fabric body 100, thereby forming a polygonal gap 300 between the coating layers 200.

[0077] Therefore, the coating layer 200 is formed in a form divided into multiple rows by the gaps 300, and the gaps 300 provide a space that can compensate for the difference in elongation between the fabric body 100 and the coating layer 200.

[0078] As described above, the method for manufacturing screen fabric according to one embodiment and the screen fabric 10 manufactured thereby are environmentally friendly and reduce disposal costs because, by manufacturing the fabric body 100 by processing biodegradable resin into yarn and weaving it, the screen fabric 10 can be recycled or biodegraded when discarded. Furthermore, by forming a gap 300 in the coating layer 200, a space is provided that can compensate for the difference in elongation between the fabric body 100 and the coating layer 200, thereby reducing the separation phenomenon of the coating layer 200 and damage to the fabric body 100 that may occur when hit by a golf ball.

[0079] The embodiments described above are illustrative, and those with ordinary skill in the art to which the embodiments belong will understand that they can be easily modified into other specific forms without altering the technical idea or essential features of the embodiments. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not limiting. For example, each component described as a single type can be implemented in a distributed manner, and similarly, components described as distributed can be implemented in a combined manner.
