Description

Technical Field

[0001] This invention relates to a method for manufacturing arch support socks and arch support socks. Background Technology

[0002] Sports socks are made of materials such as cotton and can be developed to have functions such as warmth, breathability, sweat absorption, and shock absorption.

[0003] In particular, in record-breaking competitions such as marathons and running, or in sports requiring agility such as tennis, basketball, football, and golf, slippage between the foot and sock, and between the sock and shoe, during safe and rapid changes of direction, as well as stopping and starting, can hinder the maximization of athletic performance and may also adversely affect the athlete's safety.

[0004] To improve the slippage problem of sports socks, a sports sock has been developed that includes a cushioning pad on the bottom to fill the recessed area of ​​the foot and a cushioning mechanism to ensure a tight fit between the foot and the shoe when the weight transmitted to the recessed area of ​​the foot deforms.

[0005] While the cushioning mechanism of the aforementioned sports socks can ensure a tight seal between the foot and the shoe, effectively preventing slippage, poor breathability may lead to sweaty feet.

[0006] Consequently, the aforementioned sports socks may not be able to quickly wick away sweat, leading to structural problems such as a deterioration in the cushioning mechanism.

[0007] To this end, the inventors of this invention have developed a method for manufacturing arch support socks and arch support socks that can quickly absorb and dry sweat in the anti-slip mechanism and completely prevent the sole of the foot from sliding against the shoe by means of the anti-slip mechanism. After long-term research and repeated experiments, this invention was finally completed. Summary of the Invention

[0008] The problem to be solved

[0009] According to an embodiment of the present invention, a method for manufacturing an arch support sock and an arch support sock are provided. The arch support sock has a sliding prevention mechanism at the arch portion of the sock corresponding to the arch portion of the foot. The sliding prevention mechanism can support the arch of the foot, thereby distributing the user's weight, reducing the impact with the ground and achieving foot balance, thereby reducing foot fatigue, reducing or preventing foot pain, and can quickly absorb and dry the sweat produced in the sliding prevention mechanism. At the same time, the sole of the foot is made to fit tightly with the shoe due to the sliding prevention mechanism, thereby completely preventing the sole of the foot from sliding with the shoe.

[0010] On the other hand, other objects not specified in the present invention will be considered in addition to the scope that can be readily inferred from the following detailed description and its effects.

[0011] Methods for solving problems

[0012] According to an embodiment of the present invention, a method for manufacturing an arch support sock may include: (a) mixing PVC powder and DOTP liquid resin to manufacture a resin solution; (b) adding a heat stabilizer to the resin solution and stirring; (c) removing impurities from the resin solution by sieving; (d) degassing the resin solution under vacuum; (e) filling the degassed resin solution into a molding die; (f) heating the molding die; and (g) attaching a sliding anti-adhesion mechanism removed from the molding die to the arch portion of the sock sole.

[0013] Furthermore, in step (a) above, a resin solution can be prepared by mixing PVC powder and DOTP liquid resin in a weight ratio of 1:1.5 to 1.9.

[0014] Furthermore, in step (b) above, the resin solution can be added at a ratio of 1.6 x 10 relative to 100 parts by weight. -3 ~2.4X10 -3 Add the above heat stabilizer by weight and stir for 10-15 minutes.

[0015] In step (e) above, the resin solution can be injected in such a way that the filling height of the degassed resin solution is consistent with the height of the honeycomb cavity.

[0016] In step (f) above, the molding die can be heated in an oven for 60 to 80 seconds.

[0017] In step (g) above, the anti-slip mechanism removed from the molding die can be kept at a temperature of 50–70°C at a rate of 4 kgf / cm. 2 Apply pressure to the arch area of ​​the sock for 30 seconds to perform heat bonding.

[0018] In (g) above, after removing the molded anti-slip mechanism from the above-mentioned molding die, air holes can be processed in the honeycomb unit of the anti-slip mechanism, and then it can be bonded to the arch part of the sock sole.

[0019] On the other hand, the arch support socks manufactured by the above manufacturing method can have air holes set in the honeycomb units of the slip prevention mechanism.

[0020] Invention Effects

[0021] According to one embodiment of the present invention, the method for manufacturing arch support socks and the arch support socks, by providing a slip-prevention mechanism in the sock portion corresponding to the arch of the foot, can provide the following practical effects: the slip-prevention mechanism can quickly absorb and dry the generated sweat; the slip-prevention mechanism can completely prevent the foot from sliding against the shoe by making the sole of the foot fit tightly against the shoe; and the slip-prevention mechanism can support the arch of the foot, thereby distributing the user's weight, reducing the impact with the ground and achieving foot balance, thereby reducing foot fatigue and alleviating or preventing foot pain, etc.

[0034] In describing this invention, detailed descriptions will be omitted if any related well-known functions are deemed obvious to those skilled in the art and may unnecessarily obscure the spirit of the invention.

[0035] The terminology used in this application is for illustrative purposes only and is not intended to limit the invention. Singular expressions include plural expressions unless explicitly indicated by the context. It should be understood that terms such as "comprising" or "having" in this application are intended to indicate the presence of features, numbers, steps, actions, constituent elements, components, or combinations thereof as described in the specification, and are not intended to presuppose the presence or additional possibilities of one or more other features, numbers, steps, actions, constituent elements, components, or combinations thereof.

[0036] The sizes and thicknesses of the components shown in the accompanying drawings are arbitrary for ease of illustration, and therefore the invention is not necessarily limited to the contents shown. In the drawings, the first direction can be defined as the length direction or the extension direction of the lane, the second direction can be defined as the width direction, and the third direction can be defined as the height direction.

[0037] Hereinafter, the manufacturing method of the arch support sock of the present invention and embodiments of the arch support sock will be described in detail with reference to the accompanying drawings. When describing with reference to the accompanying drawings, the same or corresponding constituent elements are given the same reference numerals, and repeated descriptions thereon are omitted.

[0038] Figure 1 This is a diagram illustrating the construction of an arch support sock according to an embodiment of the present invention.

[0039] like Figure 1 As shown, the arch support sock of the present invention can be configured to have the anti-slip mechanism 500 glued to the arch portion of the sock sole 10.

[0040] The arch support socks of the present invention can improve the fit between the foot and the ground during sports such as running, and can prevent the arch area of ​​the foot from becoming less fitted due to weight movement, thereby preventing slippage.

[0041] Furthermore, in the arch support sock of the embodiment of the present invention, the anti-slip mechanism 500 bonded to the arch portion of the sock sole 10 can effectively prevent the arch portion of the sock sole 10 from being tightly sealed with the shoe, thereby fundamentally preventing the slippage between the sole of the foot and the shoe.

[0042] In particular, in the arch support socks of the embodiments of the present invention, the anti-slip mechanism 500 of the arch portion bonded to the sock sole 10 can be composed of a hexagonal structure, i.e., honeycomb or honey paper, similar to the structure of the honeycomb unit 510.

[0043] At this time, the honeycomb cell 510 has a honeycomb or honey paper structure, which can form a very stable and gapless plane. Therefore, it can make very efficient use of space with minimal material and achieve excellent durability against compressive forces applied vertically or from top to bottom.

[0044] In addition, the honeycomb unit 510 of the anti-slip mechanism 500 may have an air hole 520 in its center, and the honeycomb unit 510 may be configured to have an air hole in whole or in part.

[0045] Figure 2 This is a structural diagram illustrating the anti-slip mechanism of an arch support sock according to an embodiment of the present invention.

[0046] like Figure 2 As shown, the anti-slip mechanism 500 of the arch support sock in an embodiment of the present invention can be configured to form the arch shape of the foot and be bonded to the arch portion of the sock sole 10 and to be tightly fitted to the inner bottom surface of the shoe.

[0047] At this time, the anti-slip mechanism 500 of the arch support sock of the present invention can be composed of honeycomb units 510, which are hexagonal structures and can be made of elastic material to have elasticity.

[0048] Here, the anti-slip mechanism 500 can transmit the compressive force generated by the weight transmitted from the arch of the foot, while simultaneously pressing the honeycomb unit 510.

[0049] In particular, although the upper part of each honeycomb unit 510 of the sock sole 10 varies in depth according to the arch shape of the foot, the lower part of each unit fits tightly against the inner bottom surface of the shoe regardless of the different sizes and depths of the arch shape of the foot, thus providing the same fit to sock wearers of all groups.

[0050] Furthermore, the anti-slip mechanism 500 is fully sealed to the inner bottom surface of the shoe while each honeycomb unit 510 is in close contact with the arch of the foot. This prevents the foot from sliding against the shoe, thereby preventing the lower body of the sock wearer from swaying and preventing injury by inducing balance between the upper and lower body.

[0051] Ultimately, the arch support sock of the present invention can transfer the weight transmitted from the arch of the foot to the inner bottom surface of the shoe through the sliding anti-slip mechanism 500 provided in the arch part of the sock sole 10, while making the entire sole of the foot and the inner bottom surface of the shoe fit together, thereby minimizing the insecurity caused by weight imbalance and achieving stable movement by ensuring a stronger fit with the ground.

[0052] In addition, the arch support socks of the present invention naturally wick away sweat generated on the soles of the feet during exercise, and the sweat wicked away from the socks can be wicked away into the shoes through the sliding anti-sweating mechanism 500.

[0053] At this time, the arch support socks of the present invention can have air holes 520 processed in each honeycomb unit 510 to facilitate the expulsion of sweat.

[0054] Here, the arch support socks of the present invention can be configured to ensure the breathability of the anti-slip mechanism 500 through the air holes 520.

[0055] Therefore, the arch support socks of the present invention can quickly absorb and discharge sweat generated on the soles of the feet to the inner bottom surface of the shoe through the air holes 520 of each honeycomb unit 510 of the sliding prevention mechanism 500, thereby achieving rapid drying.

[0056] Figure 3 This is a flowchart illustrating a method for manufacturing an arch support sock according to an embodiment of the present invention.

[0057] like Figure 3 As shown, the method for manufacturing an arch support sock according to an embodiment of the present invention may include: (a) mixing PVC powder and DOTP liquid resin in a certain proportion to manufacture a resin solution; (b) adding a heat stabilizer to the resin solution and stirring; (c) removing impurities from the resin solution by sieving; (d) degassing the mixed resin solution under vacuum to remove air bubbles; (e) filling the degassed resin solution into a molding die; (f) heating the molding die filled with the degassed resin solution; and (g) attaching a sliding anti-adhesion mechanism removed from the molding die to the arch portion of the sock sole.

[0058] First, in the method for manufacturing arch support socks according to an embodiment of the present invention, (a) the step of mixing PVC powder and DOTP liquid resin in a certain ratio to manufacture a resin solution can be carried out by mixing PVC powder and DOTP liquid resin in a weight ratio of 1:1.5 to 1.9.

[0059] At this point, polyvinyl chloride (PVC) is a polymer made from vinyl chloride, which can be manufactured by addition polymerization of vinyl chloride monomers produced by reacting ethylene obtained from petroleum with chlorine gas.

[0060] Furthermore, regarding polyvinyl chloride (PVC), if a plasticizer is added to rigid PVC, which is a colorless, transparent, and hard material, it can become soft PVC.

[0061] Table 1 below shows the physical properties of polyvinyl chloride.

[0062] [Table 1]

[0063] Physical property items hard soft proportion 1.30～1.58 1.16～1.35 Tensile strength (MPa) 41～52 11～25 Tensile modulus of elasticity (MPa) 2400～4100 - Compressive strength (MPa) 55～89 6～12 Bending strength (MPa) 69～110 -

[0064] In particular, polyvinyl chloride (PVC) has an ignition temperature of 391°C and a fire temperature of 455°C, making it a superior flame-retardant material that is more difficult to ignite or catch fire than paper, wood, and polyethylene.

[0065] In addition, PVC is not easily oxidized by oxygen in the air, has excellent durability, can exhibit high resistance to most inorganic reagents, such as acids or alkalis, and has arc resistance of 60 to 800 seconds and excellent electrical insulation. It also has excellent processability, including calendering, thermoforming, dip-molding, injection molding and machining.

[0066] Additionally, dioctyl terephthalate (DOTP) is a C-type terephthalate. 24 H 38 O4 is a colorless liquid resin with the molecular formula O4, and it is a widely used plasticizer.

[0067] Dioctyl terephthalate (DOTP), also known as bis(2-ethylhexyl) terephthalate, can be derived from terephthalic acid and 2-ethylhexanol.

[0068] DOTP is a polymer-based plasticizer that improves the flexibility, ductility, and toughness of PVC to make it suitable for various end uses. It is widely used in the production of PVC products such as cables, flooring, automotive parts, and medical devices.

[0069] DOTP can be added to adhesives and sealants to improve bond strength and flexibility, and can enhance adhesion to a variety of substrates, thereby improving the overall performance of adhesive formulations.

[0070] In particular, DOTP is an environmentally friendly, odorless liquid resin with non-toxic and biodegradable properties, making it suitable for use in skin contact formulations.

[0071] On the other hand, in the method for manufacturing arch support socks according to embodiments of the present invention, a resin solution can be manufactured by mixing PVC powder and DOTP liquid resin in a weight ratio of 1:1.5 to 1.9.

[0072] If the weight ratio of DOTP liquid resin to PVC powder is less than 1.5, the flexibility of the PVC resin may be insufficient, resulting in a decrease in its fit with the shoe. If the weight ratio exceeds 1.9, it may release harmful substances and cause environmental pollution during manufacturing steps that are carried out at high temperatures, such as the mixing or melting process.

[0073] In addition, in the method for manufacturing arch support socks according to embodiments of the present invention, step (b) of adding a heat stabilizer to a resin solution and stirring can be performed by adding a heat stabilizer to a resin solution containing PVC powder and DOTP liquid resin to maintain the physical and chemical properties of the resin solution.

[0074] At this point, heat stabilizer is a compound added during the mixing of various resins and the production of the product through processing steps in order to maintain the physical and chemical properties of the formulated resin.

[0075] The series of processes used in the mixing and manufacturing of plastics are carried out at high temperatures, so the decomposition of the resin may occur rapidly due to heat and oxygen.

[0076] In particular, PVC, which is used for a variety of purposes as a general-purpose plastic due to its low price and excellent processability, has the disadvantage of being not heat-resistant. Therefore, heat stabilizers can be used to compensate for this disadvantage.

[0077] At this point, heat stabilizers can be classified according to their form into powder, liquid, paste, and granule stabilizers, and according to their properties into Cd / Ba / Zn system, Cd / Ba system, Ba / Zn system, Ca / Zn system, Na / Za system, Sn system, Pb system, Cd system, and Zn system.

[0078] In addition, heat stabilizers can be classified according to their use into soft materials (calendering and injection processing) and hard materials (calendering and injection processing). For calendering, they can be further classified into foaming, sheet and leather processing, sol processing (sheet, leather, and foaming), and heat-resistant materials.

[0079] As the main types of heat stabilizers for PVC, lead stabilizers, metal soap stabilizers such as Ba-Cd, Ca-Zn, and Ba-Zn, and organotin stabilizers can be used.

[0080] In addition, organic stabilizers, which are not effective when used alone but produce a synergistic effect on thermal stability when used in combination with the main heat stabilizer, can be used as auxiliary stabilizers.

[0081] Lead stabilizers have excellent electrical insulation, weather resistance, and long-term thermal stability, but their drawbacks include toxicity, opacity, and the polluting effect of sulfur components. Due to their relatively low price, they can be used in a wide range of applications, such as wire covering, rigid pipes or profiles, PVC tiles, and PVC fittings.

[0082] Ba-Cd stabilizers offer excellent thermal stability and transparency, but they suffer from the problem of the heavy metal cadmium. Ba-Zn stabilizers, on the other hand, exhibit relatively good thermal stability and transparency, and are used throughout flexible PVC products. They are particularly suitable for processing paste-like resins and have lower toxicity than Ba-Cd stabilizers, thus accelerating the trend of replacing Ba-Cd stabilizers.

[0083] Ca-Zn stabilizer is a non-toxic stabilizer widely used in food packaging materials, toys, food containers, medical devices, etc. However, compared with other stabilizers, its thermal stability is poor. Therefore, it is used in combination with auxiliary stabilizers. Powder form is the mainstream, but there is a trend towards liquid phase.

[0084] Organotin stabilizers have excellent transparency and thermal stability, but may have problems such as lack of external activity, sulfur pollution caused by cadmium or lead, and the strong odor characteristic of sulfur compounds.

[0085] As inorganic and metal soap-based stabilizers, representative ones include tribasic lead sulfate (TLS), DBL, and dibasic lead phosphite (DLP). DLP and Pb-St are widely used in window products.

[0086] In the method for manufacturing sports socks according to an embodiment of the present invention, the content of heat stabilizer can be 1.6 × 10 parts per 100 parts by weight of the resin solution prepared from PVC powder and DOTP liquid resin. -3 ~2.4X10 -3 Parts by weight.

[0087] At this point, if the addition of heat stabilizer is less than 1.6 × 10 parts per 100 parts by weight relative to the resin solution prepared from PVC powder and DOTP liquid resin. -3 If the amount exceeds a certain percentage by weight, toxic gases generated during the manufacturing process may not be completely removed and may be released, posing a danger and potentially causing thermal decomposition of the PVC resin.

[0088] If the amount of heat stabilizer added is greater than 2.4 × 10 per 100 parts by weight of a resin solution prepared from PVC powder and DOTP liquid resin. -3 If the amount is in parts by weight, it cannot be completely mixed in the resin solution, which may result in some of the heat stabilizer precipitating and being burned during the melting process.

[0089] In particular, in the method for manufacturing sports socks according to embodiments of the present invention, step (b) of adding a heat stabilizer to a resin solution and stirring can be configured to add the heat stabilizer to a resin solution containing PVC powder and DOTP liquid resin and then stir thoroughly for 10 to 15 minutes.

[0090] In the method for manufacturing sports socks according to an embodiment of the present invention, step (c) of removing impurities from the resin solution by sieving can be configured to remove impurities from the resin solution by sieving through a sieve during the mixing process of adding a heat stabilizer to a resin solution prepared from PVC powder and DOTP liquid resin and then sieving the resin solution through a sieve during the mixing process.

[0091] In the method for manufacturing sports socks according to an embodiment of the present invention, the degassing step (d) of removing air bubbles from the mixed resin solution under vacuum can be performed by the following degassing operation: placing the resin solution into the vacuum chamber of a degassing device and removing air bubbles from the solution by dispersing and stirring with a paddle.

[0092] Fluids such as coatings, epoxy resins, greases, coating solutions, or sealants can undergo a degassing process to remove the air bubbles contained within them.

[0093] For example, high-viscosity fluids, such as coating solutions or sealants, which are made by mixing materials with different components, must be stirred to ensure that the components are evenly dispersed, but air bubbles may be introduced during the stirring process.

[0094] Resin solutions containing air bubbles can cause defects in the final product, so a defoaming process is necessary to remove these air bubbles.

[0095] A degasser can remove air bubbles from the resin solution in a vacuum device by drawing air out of the resin solution during the process of stirring the resin solution with the blades of the vacuum chamber.

[0096] In particular, in the method for manufacturing arch support socks according to embodiments of the present invention, the degassing step (d) in which the air bubbles of the mixed resin solution are removed under vacuum can be performed for 10 to 15 minutes, but in the case of a large amount of moisture, the degassing step can be performed for up to 30 minutes.

[0097] In addition, in the manufacturing method of the arch support socks of the present invention, the step of filling the degassed resin solution into the molding die can be performed by filling the degassed resin solution into the cavity of the molding die using an injector.

[0098] Figure 4 This is a cross-sectional schematic diagram illustrating the step (e) of filling the defoamed resin solution into the molding die in the method for manufacturing arch support socks according to an embodiment of the present invention.

[0099] like Figure 4 As shown, in the method for manufacturing arch support socks according to an embodiment of the present invention, step (e) can be configured to load the defoamed resin solution 400 into the injector 300 and then inject it into the honeycomb cavity 200 of the molding mold 100.

[0100] At this time, when the degassed resin solution 400 discharged from the injector 300 is injected into the honeycomb cavity 200 of the molding die 100, it can be controlled so that the honeycomb cavity 200 is 100% completely filled.

[0101] In other words, the degassed resin solution 400 can be injected in such a way that its filling height is consistent with the height of the honeycomb cavity 200 of the molding mold 100, so that each honeycomb unit 510 of the sliding anti-slip mechanism 500 manufactured therefrom can have the same height and achieve the same compressive stress and elasticity.

[0102] In addition, in the method for manufacturing arch support socks according to an embodiment of the present invention, the step of heating the molding die filled with the defoamed resin solution in step (f) can be configured to heat the molding die 100, which is 100% filled with the defoamed resin solution 400 in the honeycomb cavity 200, for 60 to 80 seconds using a heating mechanism such as an oven.

[0103] At this time, if the molding die 100, which is 100% filled with degassed resin solution 400 in the honeycomb cavity 200, is heated for less than 60 seconds, the sliding prevention mechanism 500 formed in the honeycomb cavity 200 of the molding die may break.

[0104] Furthermore, if the molding die 100, which is 100% filled with degassed resin solution 400 in the honeycomb cavity 200, is heated for more than 80 seconds, the sliding anti-slip mechanism 500 formed in the honeycomb cavity 200 of the molding die may burn.

[0105] In addition, if the molding die 100, which is 100% filled with degassed resin solution 400 in the honeycomb cavity 200, is subjected to a heating process using a heating mechanism such as an oven, the sliding prevention mechanism 500 can be molded to be transparent.

[0106] In the method for manufacturing arch support socks according to an embodiment of the present invention, the step of (g) attaching the sliding prevention mechanism removed from the molding die to the arch portion of the sock sole can be configured as follows: after removing the molded sliding prevention mechanism 500 from the molding die 100, the sliding prevention mechanism is attached to the arch portion of the sock sole 10.

[0107] Furthermore, in the method for manufacturing arch support socks according to embodiments of the present invention, the step of (g) attaching the sliding prevention mechanism removed from the molding die to the arch portion of the sock sole can be configured as follows: after removing the molded sliding prevention mechanism 500 from the molding die 100, air holes 520 are processed on the honeycomb units 510 of the sliding prevention mechanism 500 in whole or in part, and then the sliding prevention mechanism with air holes is attached to the arch portion of the sock sole 10.

[0108] At this point, the sock can be inserted into the sock-shaped support pad and the anti-slip mechanism 500 can be attached to the arch area of ​​the sock sole 10, and then pressed together using a press machine to bond them together.

[0109] The method of attaching the anti-slip mechanism 500 to the arch portion of the sock sole 10 can be by means of heat-pressing or by means of adhesive material.

[0110] In particular, under hot pressing conditions, it is possible to achieve a speed of 4 kgf / cm at a temperature atmosphere of 50–70°C. 2 The pressure will be applied by pressing the anti-slip mechanism 500 against the arch of the foot in the sock 10 for 30 seconds to complete the process.

[0111] Such heat-pressing conditions can prevent the anti-slip mechanism 500 from lifting off the arch of the sock sole 10, and can allow the dyeing color of the sock sole 10 to naturally transfer to the transparent anti-slip mechanism 500, thus determining the color of each honeycomb unit 510.

[0112] The arch support socks manufactured as described above can be worn in various sports environments and daily life. They are suitable for sports that require prolonged foot movement, such as golf, mountaineering, hiking, and walking, which require continuous and even use of the feet for extended periods.

[0113] However, the arch support socks of the present invention may not be suitable for sports such as football and tennis, which require rapid changes of direction and vigorous foot movements.

[0114] The arch support socks of this invention are ideal for workers who stand for long periods of time or engage in outdoor activities.

[0115] In particular, for workers who work on construction sites or stand for long periods of time outdoors or indoors, as well as those who are prone to foot fatigue or pain, or those with flat feet, wearing the arch support socks of this invention can reduce foot fatigue, relieve and prevent pain, and prevent injury.

[0116] The scope of protection of this invention is not limited to the embodiments described and illustrated above. Furthermore, it should be reiterated that the scope of protection of this invention should not be limited by obvious changes or substitutions within the technical field to which this invention pertains.
