Description

Technical Field

[0001] This invention relates to the field of shoe manufacturing technology, and specifically to an improved method for producing waterproof and breathable shoes. Background Technology

[0002] Footwear products, especially outdoor sports shoes, work shoes, and everyday waterproof shoes, have long faced the core technical challenge of effectively balancing waterproof and breathable performance. Feet produce a lot of sweat and moisture during exercise or prolonged wear. If this moisture cannot be released in time, it will lead to a damp and stuffy environment inside the shoe, affecting comfort and potentially causing health problems.

[0003] Currently, mainstream solutions focus on the waterproof and breathable design of the shoe upper (or shoe body). A common approach is to integrate a microporous waterproof and breathable membrane, such as a film based on expanded polytetrafluoroethylene (ePTFE), into the lining or composite layer of the upper. This technology allows water vapor molecules to pass through while blocking liquid water droplets, achieving a certain degree of waterproof and breathable functionality. However, the physical principles of this solution mean that its breathability is driven by temperature and humidity gradients, and the moisture evacuation path is relatively long, especially limiting its effectiveness in wicking away moisture from the sole, the primary moisture-generating area. Furthermore, with prolonged exposure to complex external environments, the membrane structure is susceptible to wear, dirt clogging, or washing, potentially leading to performance degradation.

[0004] To improve the microclimate of the feet, some existing technologies attempt to introduce breathable structures into the soles. For example, some solutions use outsole and midsole designs with simple channels or vents, attempting to create airflow through compression during walking. However, these structures often have weak waterproofing capabilities, easily absorbing liquid water directly in humid or watery environments, thus losing their waterproofing function. Other solutions attempt to integrate breathable membranes directly into the soles, but do not fully consider the enormous and complex mechanical loads that the soles bear under weight, bending, and impact. Simple sandwich structures are prone to the membrane material being compacted and cracked under repeated footsteps, or failing due to punctures by foreign objects, making their durability and reliability insufficient for practical use.

[0005] Therefore, there is an urgent need in this field for an innovative and systematic manufacturing method that can produce footwear products that not only have waterproof and breathable uppers, but also efficiently and actively expel moisture from the soles through the sole structure, and ensure that the core breathable components have excellent durability and reliable waterproofing in harsh sole environments. Summary of the Invention

[0006] The problem to be solved by the present invention is to provide an improved method for producing waterproof and breathable shoes, which significantly improves the breathability and dryness of the inside of the shoe, especially the sole area, while maintaining excellent waterproof performance, and effectively improves the wearing experience.

[0007] The technical solution provided by this invention to solve the above problems is: an improved method for producing waterproof and breathable shoes, the method comprising the following steps: S1. Prepare the upper and shoe upper components, and bond the upper and shoe upper components to form a semi-finished shoe body; S2. Prefabricated outsole breathable window module: A window is processed at a preset position on the main body of the shoe outsole. A waterproof and breathable membrane and a high-hardness microporous pressure-resistant liner are laminated and bonded together on the inner side of the window and circumferentially sealed, so that the microporous pressure-resistant liner is located on the outer side of the waterproof and breathable membrane. S3. Construct a midsole module with a protective skeleton. A ring-shaped support skeleton is formed on the lower surface of the foamed midsole body. The ring-shaped support skeleton encloses and forms a membrane protective chamber with an open top and a flat bottom. Then, the outsole breathable window module is aligned and bonded to the midsole body so that the waterproof and breathable membrane is sealed to the bottom of the membrane protective chamber. S4. Prepare a ventilated insole assembly. Open an air inlet on the insole body and cover its lower surface with an adhesive breathable and moisture-wicking layer. Then install the assembly on the upper surface of the midsole body so that the air inlet and the breathable and moisture-wicking layer are connected to the top of the membrane protection chamber. S5. Final assembly and sealing: The semi-finished shoe upper is combined with the outsole-midsole assembly using injection molding, gluing, or stitching. Then, the ventilated insole assembly is installed on the upper surface of the midsole body, connecting the air inlet and the breathable moisture-wicking layer to the top of the membrane protective chamber. Finally, the seams between the outsole and midsole, and between the midsole and upper are sealed to obtain a waterproof and breathable shoe.

[0008] Preferably, the preset position in S2 is the non-core load-bearing area of ​​the shoe outsole corresponding to the arch and / or forefoot.

[0009] Preferably, the waterproof and breathable membrane in S2 is an expanded polytetrafluoroethylene membrane.

[0010] Preferably, the compression liner in S2 is a porous mesh plate injection molded from engineering plastic or a porous plate stamped from metal.

[0011] Preferably, in step S3, the annular support skeleton and the midsole body are an integral structure formed by one-time foaming. The material density of the annular support skeleton is higher than that of other foamed areas of the midsole body.

[0012] Preferably, the material density of the annular support skeleton is higher than that of other foamed areas of the midsole body.

[0013] Preferably, the breathable and moisture-wicking layer in S4 is a three-dimensional mesh fabric or non-woven fabric.

[0014] Preferably, the sealing process in S5 is achieved by injecting sealant or hot-pressing adhesive strips.

[0015] Preferably, the method further includes the following steps: conducting a slip resistance test on the waterproof and breathable shoes made by S5: taking samples from the same batch, placing them on a shoe sole slip resistance test device, conducting a slip resistance performance test according to the standard test procedure, ensuring that the slip resistance performance meets the preset standard, and packaging the corresponding batch of samples after the test is qualified.

[0016] Preferably, the anti-slip testing device for shoe soles includes a machine base, a drive frame, a pressing component, and several test benches. The drive frame is mounted on the machine base, the pressing component is mounted on the drive frame, and the several test benches are mounted on the machine base.

[0017] Compared with the prior art, the advantages of the present invention are: the present invention sets the breathable path directly in the main sweating area of ​​the sole through the manufacturing process, and realizes the efficient conduction of moisture from the point of generation to the point of discharge by utilizing the humidity difference and thermal effect; at the same time, through the preparation of the dual physical protection structure of "compression lining" and "ring support skeleton", a safe working environment free from compression, puncture and deformation is built for the fragile waterproof and breathable membrane during the manufacturing stage, which greatly improves the life of the breathable structure of the sole.

Example 1

[0027] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a method for producing an improved waterproof and breathable shoe, the method comprising the following steps: S1. Prepare the upper and shoe upper components, and bond the upper and shoe upper components to form a semi-finished shoe body; S2. Prefabricated outsole breathable window module: A window is processed at a preset position on the main body of the shoe outsole. A waterproof and breathable membrane and a high-hardness microporous pressure-resistant liner are laminated and bonded together on the inner side of the window and circumferentially sealed, so that the microporous pressure-resistant liner is located on the outer side of the waterproof and breathable membrane. S3. Construct a midsole module with a protective skeleton. A ring-shaped support skeleton is formed on the lower surface of the foamed midsole body. The ring-shaped support skeleton encloses and forms a membrane protective chamber with an open top and a flat bottom. Then, the outsole breathable window module is aligned and bonded to the midsole body so that the waterproof and breathable membrane is sealed to the bottom of the membrane protective chamber. S4. Prepare a ventilated insole assembly. Open an air inlet on the insole body and cover its lower surface with an adhesive breathable and moisture-wicking layer. Then install the assembly on the upper surface of the midsole body so that the air inlet and the breathable and moisture-wicking layer are connected to the top of the membrane protection chamber. S5. Final assembly and sealing: The semi-finished shoe upper is combined with the outsole-midsole assembly using injection molding, gluing, or stitching. Then, the ventilated insole assembly is installed on the upper surface of the midsole body, connecting the air inlet and the breathable moisture-wicking layer to the top of the membrane protective chamber. Finally, the seams between the outsole and midsole, and between the midsole and upper are sealed to obtain a waterproof and breathable shoe.

[0028] In S2, the preset position is the non-core load-bearing area of ​​the shoe outsole corresponding to the arch and / or forefoot.

[0029] The waterproof and breathable membrane in S2 is an expanded polytetrafluoroethylene membrane.

[0030] In S2, the pressure-resistant liner is a porous mesh plate injection molded from engineering plastic or a porous plate stamped from metal.

[0031] In S3, the annular support frame and the midsole body are an integral structure formed by one-time foaming. The material density of the annular support frame is higher than that of other foamed areas of the midsole body.

[0032] The material density of the annular support skeleton is higher than that of other foamed areas of the midsole body.

[0033] The breathable and moisture-wicking layer in S4 is a three-dimensional mesh fabric or non-woven fabric.

[0034] In S5, the sealing process is achieved by injecting sealant or hot-pressing adhesive strips.

[0035] The process also includes the following steps: conducting anti-slip tests on the waterproof and breathable shoes made by S5: samples are taken from the same batch, placed on the anti-slip testing device for the sole, and the anti-slip performance is tested according to the standard testing procedure to ensure that the anti-slip performance meets the preset standard. After the test is passed, the corresponding batch of samples is packaged. Example 2

[0036] like Figure 3-12 As shown, this embodiment discloses a shoe sole anti-slip testing device, which is applied in embodiment 1. Specifically, the shoe sole anti-slip testing device includes a testing platform 1, a drive frame, a pressing component, and several testing tables. The drive frame is set on the testing platform 1, the pressing component is installed on the drive frame, and several testing tables are installed on the testing platform 1. The drive frame is used to drive the pressure assembly to move; The pressure-down component is used to provide downward pressure to the shoe being tested; The test bench includes a base 8, a sliding plate 10, a locking assembly, and several road surface simulation plates 9. The base 8 is mounted on the test platform 1. The base 8 has a sliding groove 13, within which a guide rod 11 is installed. The sliding plate 10 has guide holes that mate with the guide rods 11. Several positioning protrusions 31 are provided on the upper surface of the sliding plate 10. Several positioning recesses 32 that mate with the positioning protrusions 31 are provided on the road surface simulation plates 9. A sliding magnetic block 14 is provided at one end of the sliding plate 10. A fixed magnetic block 12 is provided on the groove wall of the sliding groove 13. The sliding magnetic block 14 and the fixed magnetic block 12 are arranged in a repulsive manner. In this design, the repulsive force between the sliding magnetic block and the fixed magnetic block provides simulated sliding resistance. This non-contact resistance method reduces mechanical wear, makes resistance changes smoother and more controllable, and allows for automatic reset, improving the durability of the device and the repeatability of the test.

[0037] In the above scheme, during the test preparation phase, the horizontal positioning and fixing of the road surface simulation board is not accomplished through complex screws or clips, but simply by placing it on the skateboard, allowing the positioning recesses on the bottom of the road surface simulation board to naturally engage with the positioning protrusions on the surface of the skateboard. This simple plug-in method achieves quick and accurate initial horizontal positioning, avoiding cumbersome alignment and tightening steps.

[0038] In the vertical direction, the road surface simulation board is stably pressed onto the skateboard surface by the downward vertical pressure applied by the hydraulic cylinder through the shoe and the pressure plate during the test, and the temporary fixation is achieved by the force of the test itself.

[0039] Therefore, once a test cycle is completed, the slide plate resets, and the locking mechanism automatically releases, the operator can easily remove the road surface simulation board by hand without any additional unlocking or loosening steps. Similarly, installing a new road surface simulation board is as simple as aligning and placing it. This design greatly simplifies the process of changing road surface simulation boards (i.e., simulated road surfaces), making switching between different test interfaces quick and easy, thereby significantly improving the usability and testing efficiency of the entire testing device.

[0040] In this embodiment, further, there are four road surface simulation plates 9. The surfaces of the four road surface simulation plates 9 are used to simulate everyday road surfaces (such as asphalt, cement, etc., the road surface simulation plates can be cast using high-hardness resin mixed with abrasives of a specific particle size (such as silicon carbide or alumina)), hard surfaces with loose particles (such as sand, gravel, or dust-covered surfaces, a standardized particle layer of about 5-10 mm thickness can be laid on the surface of the road surface simulation plate), complex interfaces with liquid and particle mixtures (a groove is designed on the surface of the road surface simulation plate, the groove is filled with a standardized particle layer of about 5-10 mm thickness and a certain volume of water is injected), and soft or deformable interfaces (such as lawn, soft mud, or soft snow, the surface of the road surface simulation plate is composed of an elastic porous material with a certain thickness and density, and there is a supporting mesh underneath); the locking assembly includes a linkage magnet 33, a locking rod 15, and L The system includes an L-shaped hook 17, a positioning mechanism, and a return spring 19. The sliding plate 10 has a locking rod hole 20 for mounting the locking rod 15. A movable hole for the linkage magnetic block 33 is located at a position corresponding to the locking rod hole 20. One end of the linkage magnetic block 33 is fixedly connected to the locking rod 15. The L-shaped hook 17 is mounted on the locking rod 15. The lower end face of the road surface simulation plate 9 has an L-shaped slot 16 that mates with the L-shaped hook 17. The L-shaped slot 16 and the locking rod hole 20 are connected via a movable channel 18, allowing the L-shaped hook 17 to move within the movable channel 18. One end of the return spring 19 is fixedly connected to the bottom of the locking rod hole 20, and the other end is fixedly connected to the locking rod 15. The positioning mechanism positions the locking rod 15 after it has moved a certain distance towards the fixed magnetic block 12. The positioning is released after the locking rod 15 returns to its original position. The linkage magnetic block and the fixed magnetic block are also arranged in a repulsive manner.

[0041] Furthermore, the positioning mechanism includes a trigger block 22, a clamping spring 26, a compression spring 24, and a positioning block 29. The wall of the locking rod hole 20 is provided with a trigger hole 28 for installing the positioning mechanism. One end of the trigger block 22 extends out of the trigger hole 28. The wall of the slide groove 13 is provided with a trigger protrusion 34 at a position corresponding to the trigger hole 28. One end of the trigger protrusion is provided with a rotatable guide roller 21. One end of the clamping spring 26 is fixedly connected to the trigger block 22, and the other end is fixedly connected to the positioning block 29. The wall of the trigger hole 28 is provided with a spring groove 25. The compression spring 24 is disposed in the spring groove 25. The trigger block 22 is provided with a stop block 23. One end of the compression spring 24 is fixedly connected to the wall of the spring groove 25, and the other end is fixedly connected to the stop block 23. The locking rod 15 is provided with a groove 27 that cooperates with the positioning block 29.

[0042] The drive frame includes a translation motor 3, a horizontal slide 2, a sliding seat 4, and a lifting bracket 5. The sliding seat 4 is mounted on the test platform 1 via a guide rail. The translation motor 3 is mounted on the test platform 1, and a lead screw is provided at the output end of the translation motor 3. The sliding seat 4 is provided with a threaded hole that mates with the lead screw. The horizontal slide 2 is mounted on the sliding seat 4, and the lifting bracket 5 is mounted on the horizontal slide 2. The pressing assembly includes a hydraulic cylinder 6 and a shoe pressing plate 7. The hydraulic cylinder 6 is fixedly mounted on the lifting bracket 5, and the pressing rod is fixedly connected to the output end of the hydraulic cylinder 6. In order to facilitate applying force to the shoe, an inner shoe fixing plate 30 is also provided on the shoe pressing plate 7. The inner shoe fixing plate 30 extends into the inside of the shoe and mates with the shoe.

[0043] In the above scheme, firstly, according to the testing requirements, a road surface simulation board simulating different road surface conditions (such as ordinary road surfaces, hard surfaces with loose particles, complex interfaces with liquid and particle mixtures, or soft and deformable interfaces) is placed on the skateboard. The positioning recesses on the lower surface of the road surface simulation board mate with the positioning protrusions on the skateboard to achieve initial positioning and alignment. Next, the shoe to be tested is placed on top of the road surface simulation board, and the hydraulic cylinder is activated. The output end of the hydraulic cylinder drives the shoe pressure plate downward, and the shoe inner fixing plate on the shoe pressure plate extends into the shoe and engages with the shoe, thereby applying vertical downward pressure to the shoe. Subsequently, the translation motor is activated. The translation motor drives the sliding seat to move horizontally along the guide rail through the lead screw drive, thereby causing the horizontal slide, lifting bracket, and the downward pressure assembly installed on it to move horizontally as a whole, thus giving the shoe a horizontal traction force. Under the action of the horizontal force, the shoe relies on the friction between the sole and the surface of the road surface simulation board to move the road surface simulation board and the skateboard below together along the guide rod direction. When moving, the sliding magnetic block at one end of the slide plate and the fixed magnetic block on the slide groove wall repel each other, generating a repulsive force. This repulsive force gradually increases as the distance between the sliding magnetic block and the fixed magnetic block decreases.

[0044] As the slide moves the road simulation board, the trigger block inside the slide contacts the trigger protrusion on the slide groove wall and the guide roller at its end. Under the squeezing action of the guide roller, the trigger block is pressed into the trigger hole, and the stop block on it compresses the spring. At the same time, the trigger block drives the clamping spring and the positioning block to move together. The positioning block then abuts against the outer surface of the locking rod until the linkage magnet, under the repulsive force of the fixed magnet, drives the locking rod to continue moving, causing the slot on the locking rod to move to the position corresponding to the positioning block. At this time, the positioning block is engaged in the slot under the elastic force of the clamping spring, thus positioning the locking rod. Simultaneously, the L-shaped hook on the locking rod enters and engages with the L-shaped slot on the lower surface of the road simulation board, thereby locking the road simulation board onto the slide through the locking assembly.

[0045] As the shoe continues to move the road surface simulation board, the repulsive force between the sliding and fixed magnetic blocks increases. When this repulsive force exceeds the maximum static friction between the sole and the road surface simulation board, relative sliding occurs, causing the shoe to slip. Subsequently, the skateboard and the road surface simulation board move in opposite directions under the repulsive force between the sliding and fixed magnetic blocks until the skateboard returns to its original position. During this return process, the trigger block disengages from the trigger cam and guide roller. The trigger block, under the restoring force of the compression spring, returns to its original position, causing the positioning block to disengage from the locking rod's slot, thus releasing the locking rod's position. Simultaneously, the locking rod, under the tension of the return spring, moves in the opposite direction, causing its L-shaped hook to disengage from the L-shaped latch on the road surface simulation board, releasing the board's lock. At this point, the test bench returns to its initial state, facilitating the replacement of the road surface simulation board for the next test. Throughout the process, the anti-slip performance of the sole on the corresponding simulated interface can be evaluated by measuring the horizontal force or related parameters when the shoe slips.

[0046] After the test, the shoe detaches from the road surface simulation board, and there is no longer any vertical pressure on the board. At this point, the skateboard will move in the opposite direction (reset direction) at high speed due to the strong repulsive force between the sliding and fixed magnetic blocks. Without a locking mechanism, the road surface simulation board may bounce off the skateboard, shift, or even fall off due to inertia, causing damage or affecting subsequent tests.

[0047] Therefore, the locking mechanism designed in this scheme plays a crucial role in security protection. Its working logic is as follows: During the test, when the shoe moves the road simulation board and skateboard against the magnetic force to the trigger point, the locking mechanism automatically activates, firmly locking the road simulation board onto the skateboard, making the two a single unit. This locked state will remain until the entire reset process is basically completed.

[0048] Specifically, throughout the entire reset process, the L-shaped hook and L-shaped latch remain engaged, securing the road surface simulation board to the slide plate, and both smoothly return to their initial positions. Only after the slide plate is fully reset and the trigger block disengages from the trigger protrusion, does the positioning block retract from its slot. The reset spring then pulls the locking rod back, disengaging the L-shaped hook from the latch. In other words, the unlocking action occurs after the reset process is complete.

[0049] This avoids the risk of the road surface simulation board flying off due to the impact of resetting. The entire "lock-test-reset-unlock" cycle is fully automated, requiring no manual intervention, which ensures both the safety of the test component (road surface simulation board) and the smoothness and reliability of the testing process.
