[0044] A screen fabric 10 for a golf simulator according to one embodiment is a member that is installed in a golf simulator and provides images of a golf simulation game while being hit by a golf ball.

[0045] Referring to FIGS. 1 and 2, the screen fabric 10 according to one embodiment may be configured to include a fabric body 100 and a coating layer 200.

[0046] The fabric body 100 forms the body of the screen fabric 10, and may be obtained by processing a biodegradable resin (poly(lactic acid) (PLA)) into yarn and weaving the yarn into a fabric with a predetermined area.

[0047] In this case, the 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.

[0048] Since the biodegradable resin is made from ingredients extracted from natural sources, it is environmentally friendly, non-toxic, highly biodegradable, and biocompatible, and thus is a material for solving environmental pollution problems and is used as an alternative to plastic materials.

[0049] Since the fabric body 100 is obtained by processing the biodegradable resin into yarn and weaving the yarn into a fabric with a predetermined area as described above, it may be recycled or microbially biodegraded when disposed of, and thus has the advantage of being environmentally friendly.

[0050] The coating layer 200 is a component that is formed by applying a coating solution to at least one of both surfaces of the fabric body 100 and serves to protect the fabric body 100.

[0051] The coating layer 200 is preferably formed only on the front surface of the fabric body 100, which is hit by a golf ball, without being limited thereto, and may be formed on both surfaces of the fabric body 100.

[0052] In this case, the coating layer 200 may be composed of a coating solution containing at least one of polyurethane and silicone and formed on the fabric body 100 to have a thickness of 2 to 4 mm.

[0053] Meanwhile, since the coating layer 200 has an elongation (i.e., degree of stretching) different from that of the fabric body 100, a phenomenon may occur in which the costing layer is separated from the fabric body 100 when hit by a golf ball.

[0054] In order to reduce the above phenomenon, in the screen fabric 10 according to one embodiment, as shown in FIG. 1, the coating layer 200 may be formed by stripe coating to have a gap 300 that may provide a space capable of compensating for the difference in elongation.

[0055] More specifically, the gap 300 is formed in the coating layer 200 to expose the fabric body 100 while dividing the coating layer 200 into multiple stripes, thereby providing a space that may compensate for the difference in elongation between the fabric body 100 and the coating layer 200 through the exposed portion of the fabric body 100.

[0056] In this case, as shown in FIG. 1, the gap 300 and each stripe of the coating layer 200 divided into multiple stripes by the gap 300 may be formed to have a width smaller than the maximum diameter of a golf ball 1.

[0057] In addition, the gap 300 and each stripe of the coating layer 200 divided into multiple stripes by the gap 300 may be formed to have a width that allows at least two gaps 300 to be positioned within a region corresponding to the maximum diameter of the golf ball 1.

[0058] For example, each stripe of the coating layer 200 may be formed to have a width of 15 to 20 mm, and the gap 300 may be formed to have a width of 0.5 to 1 mm. Accordingly, at least two gaps 300 may be positioned within a region corresponding to the maximum diameter (42.87 mm) of the golf ball to provide a buffer space.

[0059] Meanwhile, as shown in FIGS. 7 to 9, regions of 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, and the gap 300 may be formed in a polygonal shape between polygonal regions of the coating layers 200 to expose the fabric body 100.

[0060] More specifically, each of the coating layer 200 and the gap 300 may be formed in a triangular shape as shown in FIG. 7, or may be formed in a square shape as shown in FIG. 8. Alternatively, as shown in FIG. 9, the coating layer 200 and the gap 300 may be formed in a hexagonal shape and a tetragonal shape, respectively.

[0061] Meanwhile, as shown in FIGS. 7 to 9, the coating layer 200 having a polygonal shape and the gap 300 having a polygonal shape may be formed to have an area smaller than the maximum diameter of the golf ball 1.

[0062] In addition, the coating layer 200 having a polygonal shape and the gap 300 having a polygonal shape may each be formed to have an area that allows at least two gaps 300 to be positioned within a region corresponding to the maximum diameter of the golf ball 1.

[0063] The coating layer 200 having a polygonal shape and the gap 300 having a polygonal shape may reduce cracks in the coating surface caused by impact when hit by the golf ball 1 and maintain the tensile strength of the fabric body 100. In addition, since they are formed in a polygonal shape, unlike the golf ball 1 having a circular shape, they may have the effect of maintaining the coating strength (adhesion).

[0064] Hereinafter, a method for manufacturing the screen fabric 10 according to one embodiment will be described with reference to FIGS. 2 to 5.

[0065] A method for manufacturing the screen fabric according to one embodiment may include a fabric body manufacturing step S100, a CIRE processing step S200, and a coating step S300.

[0066] The fabric body manufacturing step S100 is a process of manufacturing the fabric body 100 described above. As shown in FIG. 4, step S100 may include a processing step S110, a step S120 of manufacturing yarn, a step S130 of weaving the yarn into the fabric body, and a post-processing step S140.

[0067] The processing step S110 is a process of processing a biodegradable resin into fibers. In this step, the biodegradable resin may be processed into staple fibers and filaments.

[0068] 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, while filaments are made by making long fibers into a single thread, and their thickness is expressed in units of denier.

[0069] More specifically, in the processing step S110, the biodegradable resin raw material may be melted and extruded, and then filaments and staple fibers may be made through stretching, clamping, and cutting processes.

[0070] The yarn manufacturing step S120 is a step of manufacturing yarn by processing filaments and staple fibers into yarn. More specifically, a covering yarn may be manufactured through a covering process in which filaments are rolled around staple fibers, and then yarn may be manufactured through a twisting process in which multiple strands of the covering yarn are twisted.

[0071] In this case, in the yarn manufacturing step S120, yarn may be manufactured using, for example, filaments of 250 to 500 denier and staple fibers of 10 to 40 counts, and the tensile and bursting strength of the yarn may be adjusted through two- or three-ply twisting.

[0072] The step S130 of weaving the yarn into the fabric body is a process of making a fabric body 100 with a predetermined area by weaving the yarn into warp and weft. The fabric body 100 may be manufactured by weaving the yarn into a plain weave or twill weave.

[0073] As is known, plain weaving is a weaving method in which warp and weft yarns are alternately crossed one by one, while twill weaving is a weaving method in which the numbers of warp and weft yarns crossing each other are different.

[0074] For example, in the step S130 of weaving the yarn into the fabric body, the yarns may be woven into a twill weave in which the number of weft and warp yarns crossing each other is to .

[0075] Accordingly, as shown in FIG. 6, the fabric body 100 may have a diagonal pattern of yarns.

[0076] The post-processing step S140 is a step of post-processing the manufactured fabric body 100.

[0077] More specifically, in the post-processing step S140, the fabric body may be subjected to a refining process to remove impurities, and then dyed, and the dyed fabric body may be flame-retardant treated, and then water-repellent treated to lower the moisture absorption rate of the fabric body 100, thereby completing the fabric body 100.

[0078] The CIRE processing step S200 is a process of increasing the resolution of the structure of the post-processed fabric body 100, and may be performed by pressing the fabric body 100 with a predetermined pressure through rollers at a predetermined temperature.

[0079] For example, in the CIRE processing step S200, the resolution of the structure of the fabric body 100 may be increased by pressing the fabric body 100 with a roller pressure of 30 to 60 tons at a temperature of 180 to 240 C.

[0080] The coating step S300 is a process of forming the above-described coating layer 200 by applying a coating solution to at least one of both surfaces of the fabric body 100 while forming the above-described gap 300 in the coating layer 200.

[0081] In this coating step S300, the fabric body 100 may be coated with a coating solution containing at least one of polyurethane and silicone to a thickness of 2 to 4 mm as described above. As the coating method, a knife coating method or a foam coating method may be applied, and in addition, any method of coating the fabric with the coating solution may be applied.

[0082] More specifically, in the coating step S300, as shown in FIG. 5, the coating layer 200 may be formed in a stripe shape 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 to form a first row of a coating layer in step S310, and then repeatedly forming multiple rows of a coating layer 200, each having the same width as the first row of the coating layer, so as to be spaced apart from each other by the above-described gap 300 in step S320.

[0083] Meanwhile, in the coating step S300, a first polygonal region of a coating layer may be formed by applying a coating solution to the fabric body 100 in a polygonal shape, and then polygonal regions of a coating layer may be repeatedly formed in the length direction and width direction of the fabric body 100 while forming the gap 300 in a polygonal shape between the polygonal regions of the coating layers 200.

[0084] Accordingly, the coating layer 200 may be formed in a form divided into multiple rows by the gap 300, and a space that may compensate for the difference in elongation between the fabric body 100 and the coating layer 200 may be provided through the gap 300.

[0085] As described above, according to the method for manufacturing a screen fabric according to one embodiment and the screen fabric 10 manufactured thereby, the fabric body 100 is manufactured by processing biodegradable resin into yarn and weaving the yarn, and thus the screen fabric 10 may be recycled or biodegraded when disposed of, indicating that it is environmentally friendly and disposal costs may be reduced. In addition, since the gap 300 is formed in the coating layer 200 to provide a space that may compensate for the difference in elongation between the fabric body 100 and the coating layer 200, the separation of the coating layer 200 and damage to the fabric body 100, which may occur when impacted by a golf ball, may be reduced.

[0086] The above-described embodiments are intended for illustrative purposes. It will be understood that those having ordinary knowledge in the art to which the present invention pertains can easily make modifications and variations without changing the technical spirit and essential features of the present invention. Therefore, the above-described embodiments are illustrative and are not limitative in all aspects. For example, each component described as being in a single form may be practiced in a distributed form. In the same manner, components described as being in a distributed form may be practiced in an integrated form.

[0087] The scope of protection pursued through the present specification should be defined by the attached claims, rather than the detailed description. All modifications and variations which are derived from the meanings, scopes and equivalents of the claims should be construed as falling within the scope of the present invention.
