Description

Technical Field

[0001] This invention relates to the field of textile anti-wrinkle treatment equipment, and in particular to an anti-wrinkle composite treatment device and method for four-way elastic fabric. Background Technology

[0002] Four-way stretch fabric is widely used in the production of various clothing and home textile products due to its good elasticity and extensibility. However, during the processing of this type of fabric, wrinkles may occur due to tension fluctuations, stretching deformation, and differences in fiber shrinkage. If not handled properly, these wrinkles may seriously affect the quality of the product.

[0003] Traditional wrinkle-resistant treatments for four-way stretch fabrics often involve manual soaking and natural air drying, which is not only inefficient but also results in inconsistent wrinkle-resistant effects due to the difficulty in evenly penetrating the fabric with the anti-wrinkle solution. While some automated processing equipment can achieve soaking and drying, its fixed stirring structure prevents comprehensive and uniform mixing of the anti-wrinkle solution, easily leading to stratification of the solution components and affecting the penetration effect. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention proposes a four-sided elastic fabric anti-wrinkle composite treatment device and method, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for anti-wrinkle composite treatment of four-way elastic fabric includes a body and a stirring unit fixedly connected to the body for stirring the finishing liquid raw material in the body. A pressing unit is fixedly connected to both sides of the top of the body, a drying unit is fixedly connected to both sides of the body, a fabric lifting unit is connected to both sides of the bottom of the inner wall of the body, and a draining unit is also connected to the body for discharging the anti-wrinkle finishing liquid. The mixing unit includes a mounting plate fixedly connected to the rear of the machine body and a movable component fixedly connected to the top of the mounting plate. A drive component is fixedly connected to the movable component, and a rotating platform is fixedly connected to the top of the movable component. A mixing component is fixedly connected to the end of the rotating platform away from the movable component. The mixing component includes a support platform fixedly connected to the rotating platform and away from the movable component, and a mounting groove formed on the support platform and away from the movable component. A telescopic cylinder is fixedly connected to the mounting groove. One end of a telescopic guide rod is fixedly connected to the front of the support platform, and a support plate is fixedly connected to the other end of the telescopic guide rod. The output end of the telescopic cylinder passes through the support platform and is fixedly connected to the support plate. A first... The third geared motor has an output end that passes through a support plate and is fixedly connected to a connecting rod. A stirring component is provided at the end of the connecting rod away from the support plate. The stirring component includes a locking block installed in an arc-shaped groove at the end of the connecting rod away from the support plate. An internal threaded hole is opened on the side end of the locking block. A drive column is fixedly connected to the bottom end of the locking block. A triangular plate is fixedly connected to the other end of the drive column. Multiple stirring rods are fixedly connected to the end of the triangular plate away from the drive column. A ring-shaped baffle is fixedly connected to the outer surface of the stirring rod. An irregularly shaped column is fixedly connected to the center position at the end of the triangular plate away from the drive column. The irregularly shaped column has a protruding structure in the middle. An extension extending towards the stirring rod is provided at the top end of the irregularly shaped column near the drive column.

[0006] Furthermore, the moving component includes two slide rails fixedly connected to the top of the mounting plate and a slider slidably connected to the outer surface of the two slide rails. A base is provided between the two slide rails, and a screw is rotatably connected inside the base. A housing is threadedly connected to the outer surface of the screw, and a top rod is slidably connected to the top of the housing. A drive groove is provided on the side of the housing near the drive component. A telescopic plate is fixedly connected to the end of the slider away from the slide rail. A first reduction motor is fixedly connected to one side of the base. The output end of the first reduction motor passes through the base and extends into the base and is fixedly connected to one end of the screw. Vertically distributed toothed grooves are provided on the outer surface of the top rod.

[0007] Furthermore, the drive assembly includes a fixed block fixedly connected to one side of the telescopic plate and a second reduction motor fixedly connected to one end of the fixed block. The output end of the second reduction motor passes through the fixed block and is fixedly connected to a drive rod. A drive gear is fixedly connected to the end of the drive rod away from the second reduction motor, and the drive gear meshes with the push rod.

[0008] Furthermore, the rotating platform includes a connecting platform fixedly connected to the top of the moving component and a rotating disk rotatably connected to the top of the connecting platform via a damping bearing. The outer surface of the rotating disk has multiple insertion holes arranged in a ring. A limit block is fixedly connected to one side of the top of the connecting platform, and a pin for inserting into the insertion hole of the rotating disk is slidably connected on the limit block.

[0009] Based on the same inventive concept, a method for preventing wrinkles in four-way elastic fabric is also proposed, employing the aforementioned composite treatment device for preventing wrinkles in four-way elastic fabric, including the following steps: S1. Pretreatment: Conduct an appearance inspection on the four-way stretch fabric, and measure the fabric width and weight parameters; soak the four-way stretch fabric in clean water at 30℃~40℃ for 15 minutes~20 minutes, and then gently rinse it 2 to 3 times in a washing machine at a speed of 100 rpm~200 rpm. S2. Pre-setting: Place the cleaned four-way stretch fabric into the tenter frame, set the temperature to 180℃~190℃, and the speed to 20m / min~30m / min for pre-setting. S3. Prepare finishing solution raw materials: Prepare 3% to 5% of the total finishing solution raw materials, silicone softener, 8% to 12% of dimethyloldihydroxyvinyl urea anti-wrinkle finishing agent, 0.5% to 1% of magnesium chloride catalyst, 0.2% to 0.5% of penetrant and the balance water. S4. Composite treatment: Pour the finishing liquid raw material prepared in step S3 into the four-way stretch fabric anti-wrinkle composite treatment device. The four-way stretch fabric anti-wrinkle composite treatment device is continuously stirred for 30 to 40 minutes to make an anti-wrinkle finishing liquid. The four-way stretch fabric that has been pre-shaped in step S2 is sent into the four-way stretch fabric anti-wrinkle composite treatment device to fully immerse the fabric in the anti-wrinkle finishing liquid for more than 20 minutes. Then, the soaked four-way stretch fabric is dried by the four-way stretch fabric anti-wrinkle composite treatment device. S5. Post-treatment: Put the dried four-way stretch fabric into a washing machine, add an appropriate amount of neutral detergent at 40℃~50℃ and wash for 15 minutes~20 minutes. Then, after dehydrating the four-way stretch fabric, put it into a dryer and dry at 80℃~90℃ for 20 minutes~30 minutes. S6. Quality Inspection: Check whether the surface of the treated four-way stretch fabric is flat and free from defects such as wrinkles, color spots, and color variations.

[0010] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: The specially designed stirring component of this invention, through the coordinated operation of the stirring rod with arc-shaped baffles on the edge of the triangular plate and the irregularly shaped column at the center, can transform a single circular motion into complex turbulence. The fluid guiding effect generated by the arc-shaped baffles significantly improves the shearing efficiency and effectively promotes the emulsification and dispersion of the poorly soluble components in the anti-wrinkle finishing liquid. The irregularly shaped column has a radially outward-extending and stepped-turning convective structure in the middle. Utilizing the geometric abrupt change in its rotation trajectory, a vertical pressure gradient is established at the stirring center. The axial suction effect generated by this pressure gradient induces the finishing liquid at the bottom of the machine to form a convective circulation that rolls from bottom to top. This completely solves the problems of heavy components easily depositing at the bottom and the formation of ineffective vortex dead zones in the center in traditional stirring equipment. The top of the irregular column is provided with an extension that extends towards the stirring rod. This extension and the high-speed rotating stirring rod on the periphery form a high-frequency shear interference zone, which can further break up the agglomerates of the agents in the finishing liquid. Through the above-mentioned composite fluid dynamics design, it is ensured that the components of the anti-wrinkle finishing liquid, such as silicone softener and anti-wrinkle finishing agent, are uniform at the microscopic level, thus eliminating quality defects such as color spots, color variations and uneven anti-wrinkle effect after elastic fabric treatment.

[0011] Through the cooperation of moving components, drive components, rotating platforms and telescopic cylinders, the stirring component can achieve multi-dimensional movements of horizontal, vertical, rotation and forward and backward extension. It can accurately adjust the stirring position according to different liquid levels and process requirements, and can flexibly avoid other processes such as pressing and drying. The whole machine integrates wetting, stirring, pressing, cloth lifting, drying and liquid drainage, which greatly shortens the process flow time and reduces the intensity of manual labor.

[0012] Furthermore, because four-way stretch fabric contains elastic fibers such as spandex, it is prone to shrinkage and deformation when exposed to high temperatures or chemical agents. This anti-wrinkle treatment method for four-way stretch fabric innovatively introduces a pre-conditioning process S2 at 180℃~190℃ before the composite impregnation treatment S4. This eliminates internal stress within the fabric in advance, stabilizes the fabric width, and effectively prevents severe shrinkage and curling during subsequent soaking and drying processes, significantly improving the dimensional stability of the finished product. In step S3, a specific ratio of silicone softener, anti-wrinkle agent, and magnesium chloride catalyst is formulated for four-way stretch fabric. An appropriate amount of dimethyloldihydroxyethylene urea anti-wrinkle agent, catalyzed by magnesium chloride, can undergo a full cross-linking reaction with the fibers, giving the fabric excellent anti-wrinkle properties. Simultaneously, the addition of silicone softener compensates for the common problem of fabric becoming stiff and brittle after anti-wrinkle resin treatment, maximizing the preservation of the original high elasticity and soft, skin-friendly feel of the four-way stretch fabric. In step S4, the four-way stretch fabric anti-wrinkle composite treatment device is used to continuously stir for 30 to 40 minutes to ensure deep emulsification of the agent. The fabric is then completely soaked for 20 minutes and dried in situ. The precise downward pressure wetting and rapid in-situ drying and shaping of the equipment are seamlessly integrated, ensuring that the anti-wrinkle agent is firmly fixed inside the fibers before migration or volatilization, significantly improving the durability of the anti-wrinkle effect and its washability. The neutral washing and secondary drying process in step S5 thoroughly removes unreacted residual resin, catalyst, and surface liquid from the fabric surface. This not only further improves the smoothness and color purity of the fabric but also significantly reduces the formaldehyde residue, ensuring that the final four-way stretch fabric meets the safety and environmental protection standards of the apparel and home textile industries.

Detailed Implementation

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] refer to Figures 1 to 12 This embodiment provides a device for anti-wrinkle composite treatment of four-way elastic fabric, including a body 1 and a stirring unit 2 fixedly connected to the body 1 for stirring the finishing liquid raw material inside the body 1. A pressing unit 3 is fixedly connected to both sides of the top of the body 1. The pressing unit 3 is used to press down the four-way elastic fabric inside the body 1 to immerse it in the anti-wrinkle finishing liquid. A drying unit 4 is fixedly connected to both sides of the body 1. The drying unit 4 is used to input heated air into the body 1 to dry the four-way elastic fabric. A fabric lifting unit 5 is connected to both sides of the bottom of the inner wall of the body 1. A draining unit 6 is also connected to the body 1 for discharging the anti-wrinkle finishing liquid.

[0028] The stirring unit 2 includes a mounting plate 21 fixedly connected to the rear of the body 1 and a moving component 22 fixedly connected to the top of the mounting plate 21. A drive component 23 is fixedly connected to the moving component 22. A rotating platform 24 is fixedly connected to the top of the moving component 22. A stirring component 25 is fixedly connected to the end of the rotating platform 24 away from the moving component 22. The stirring component 25 is used to stir the liquid inside the body 1.

[0029] The machine body 1 serves as a processing carrier, holding the anti-wrinkle finishing liquid and the four-way stretch fabric to be treated. The stirring unit 2 can stir the anti-wrinkle finishing liquid in all directions to prevent the components of the anti-wrinkle finishing liquid from separating and ensure that the four-way stretch fabric is evenly soaked. The pressing unit 3 can accurately press the four-way stretch fabric into the anti-wrinkle finishing liquid to avoid insufficient soaking caused by floating. The drying unit 4 can quickly dry the four-way stretch fabric and set its shape. The fabric lifting unit 5 facilitates the removal of the treated four-way stretch fabric. The draining unit 6 can filter and discharge the waste liquid (used anti-wrinkle finishing liquid) to achieve resource recycling and environmentally friendly discharge. In the stirring unit 2, the mounting plate 21 provides a stable mounting base for the moving component 22. The moving component 22 can drive the stirring component 25 to move horizontally. The drive component 23 provides power for the lifting and lowering of the stirring component 25. The rotating platform 24 can adjust the angle of the stirring component 25 so that the stirring component 25 can cover all areas inside the machine body 1, greatly improving the uniformity of stirring and ensuring that the components of the anti-wrinkle finishing liquid are fully mixed, thus ensuring that the four-way stretch fabric is evenly soaked.

[0030] The mixing assembly 25 includes a support platform 251 fixedly connected to the end of the rotating platform 24 away from the moving assembly 22, and a mounting groove 250 opened at the end of the support platform 251 away from the moving assembly 22. A telescopic cylinder 252 is fixedly connected in the mounting groove 250. One end of a telescopic guide rod 253 is fixedly connected to the front of the support platform 251. The other end of the telescopic guide rod 253 is fixedly connected to a support plate 255. The output end of the telescopic cylinder 252 passes through the support platform 251 and is fixedly connected to the support plate 255. A third reduction motor 254 is fixedly connected to the top of the support plate 255. The output end of the third reduction motor 254 passes through the support plate 255 and is fixedly connected to a connecting rod 256. A mixing element 258 is provided at the end of the connecting rod 256 away from the support plate 255. A connecting bolt 257 is detachably connected to the top of the mixing element 258.

[0031] The support platform 251 provides an installation base for the telescopic cylinder 252 and the telescopic guide rod 253. The telescopic cylinder 252 can drive the support plate 255 to adjust its position back and forth. The telescopic guide rod 253 ensures that the support plate 255 runs smoothly. The third reduction motor 254 drives the connecting rod 256 to rotate the stirring component 258, thereby agitating the anti-wrinkle finishing liquid. The end of the connecting rod 256 is engaged with the connecting bolt 257, which allows the stirring component 258 to be quickly disassembled and replaced. This facilitates the replacement of different specifications of the stirring component 258 according to the viscosity of the anti-wrinkle finishing liquid and the type of four-sided elastic fabric, thereby improving the mixing adaptability. This structure has both back and forth position adjustment and stirring functions, and can accurately control the stirring depth and stirring intensity to ensure uniform mixing of the anti-wrinkle finishing liquid.

[0032] The mixing component 258 includes a locking block 2581 installed in an arc-shaped groove at the end of the connecting rod 256 away from the support plate 255. The locking block 2581 has an internal threaded hole 2580 on its side. A drive column 2582 is fixedly connected to the bottom of the locking block 2581. A triangular plate 2583 is fixedly connected to the other end of the drive column 2582. Multiple mixing rods 2584 are fixedly connected to the end of the triangular plate 2583 away from the drive column 2582. A ring-shaped distribution of... The arc-shaped baffle plate 2583 has a triangular plate 2583 with a shaped column 2585 fixedly connected to the center of the end away from the drive column 2582. The shaped column 2585 has a protruding structure in the middle, and the top of the shaped column 2585 has an extension extending towards the stirring rod 2584 near the drive column 2582. The arc-shaped baffle plate on the surface of the stirring rod 2584 can effectively break the laminar flow state of the anti-wrinkle finishing liquid when rotating, transforming the single circular motion into complex turbulence, and utilizing the arc surface to generate The fluid guiding effect significantly improves shear efficiency and promotes the emulsification and dispersion of poorly soluble components such as silicone softeners. The shaped column 2585 has a radially outward-extending, stepped-turning protrusion structure in the middle. Utilizing the geometric abrupt change in its rotation trajectory, a vertical pressure gradient is established at the stirring center. The axial suction effect generated by this pressure gradient induces the finishing liquid at the bottom of the machine to form a convective circulation that rolls from bottom to top. This effectively solves the problem of heavy components easily depositing at the bottom and the formation of ineffective vortex dead zones in the center. The extension at the top of the shaped column protrudes towards the stirring rod 2584, creating a high-frequency shear interference zone between the central column and the outer stirring rod 2584, further pulverizing agent agglomerates. The synergistic effect of the three achieves all-round, dead-angle-free uniform mixing of the anti-wrinkle finishing liquid, ensuring uniform liquid absorption in all parts of the four-sided elastic fabric. This eliminates quality defects such as color spots, color variations, and uneven anti-wrinkle effects from the root, significantly improving the flatness and appearance quality of the finished fabric.

[0033] The locking block 2581 is engaged in the arc-shaped groove of the connecting rod 256 and fixed by the connecting bolt 257, making it easy to assemble and disassemble. The driving column 2582 drives the triangular plate 2583 to rotate, and multiple stirring rods 2584 rotate with the triangular plate 2583 to stir the anti-wrinkle finishing liquid. The arc-shaped baffle on the outer surface of the stirring rod 2584 can enhance the turbulence effect during stirring, so that the anti-wrinkle finishing liquid forms a vortex and improves the mixing uniformity. The irregular column 2585 at the center position can break the laminar flow state of the anti-wrinkle finishing liquid and further enhance the stirring effect. The stirring component 258 has a reasonable structural design, high stirring efficiency, and can effectively prevent the components of the anti-wrinkle finishing liquid from separating, ensuring that the elastic fabric on all four sides is evenly impregnated.

[0034] The moving component 22 includes two slide rails 222 fixedly connected to the top of the mounting plate 21 and a slider 225 slidably connected to the outer surface of the two slide rails 222. A base 223 is provided between the two slide rails 222. A screw 224 is rotatably connected inside the base 223. A housing 227 is threadedly connected to the outer surface of the screw 224. A top rod 228 is slidably connected to the top of the housing 227. A drive groove 221 is provided on the side of the housing 227 near the drive component 23. A telescopic plate 226 is fixedly connected to the end of the slider 225 away from the slide rails 222. A first reduction motor 229 is fixedly connected to one side of the base 223. The output end of the first reduction motor 229 passes through the base 223 and extends into the base 223 and is fixedly connected to one end of the screw 224. Vertically distributed toothed grooves 220 are provided on the outer surface of the top rod 228.

[0035] Two parallel slide rails 222 cooperate with the slider 225 to guide the horizontal movement of the stirring assembly 25, ensuring a smooth and uninterrupted movement. The first reduction motor 229 drives the screw 224 to rotate, which can drive the outer shell 227 to slide horizontally along the screw 224, thereby driving the stirring assembly 25 to move. The telescopic plate 226 can move synchronously with the slider 225 to provide stable support for the drive assembly 23. The toothed groove 220 on the outer surface of the top rod 228 can mesh with the drive gear 234 of the drive assembly 23 to realize the vertical lifting and lowering of the top rod 228, thereby driving the stirring assembly 25 to adjust its height to adapt to the stirring requirements of anti-wrinkle finishing liquid at different liquid levels. This structure, through the combination of horizontal movement and vertical lifting, greatly increases the coverage of the stirring assembly 25, ensuring that the anti-wrinkle finishing liquid inside the machine body 1 can be fully stirred.

[0036] The drive assembly 23 includes a fixed block 232 fixedly connected to one side of the telescopic plate 226 and a second geared motor 231 fixedly connected to one end of the fixed block 232. The output end of the second geared motor 231 passes through the fixed block 232 and is fixedly connected to a drive rod 233. A drive gear 234 is fixedly connected to the end of the drive rod 233 away from the second geared motor 231. The drive gear 234 meshes with the push rod 228.

[0037] The fixing block 232 fixes the second reduction motor 231 to the telescopic plate 226, ensuring that the second reduction motor 231 does not shake during the driving process. The second reduction motor 231 drives the drive gear 234 to rotate through the drive rod 233. The drive gear 234 meshes with the tooth groove 220 of the top rod 228, converting the rotational motion of the second reduction motor 231 into the vertical lifting motion of the top rod 228, thereby driving the stirring assembly 25 to adjust its height. This driving method has high transmission efficiency and precise control. It can accurately adjust the stirring depth of the stirring assembly 25 according to the liquid level of the anti-wrinkle finishing liquid and the thickness of the four-sided elastic fabric, avoiding collision between the stirring assembly 25 and the four-sided elastic fabric or the bottom of the machine body 1, while ensuring that the anti-wrinkle finishing liquid is fully stirred, thus improving the wetting effect.

[0038] The rotating platform 24 includes a connecting platform 241 fixedly connected to the top of the moving component 22 and a rotating disk 242 rotatably connected to the top of the connecting platform 241 via a damping bearing. The outer surface of the rotating disk 242 has a plurality of insertion holes 240 arranged in a ring. A limiting block 243 is fixedly connected to one side of the top of the connecting platform 241. A pin 244 for inserting into the insertion hole 240 of the rotating disk 242 is slidably connected on the limiting block 243.

[0039] The connecting platform 241 provides a mounting base for the rotating disk 242. The damping bearing allows the rotating disk 242 to rotate flexibly and stop at any angle, facilitating the adjustment of the stirring angle of the stirring component 25. The annular insertion hole 240 on the outer surface of the rotating disk 242 cooperates with the pin 244 on the limiting block 243 to lock the rotating disk 242 at a preset angle, preventing angle deviation due to vibration during stirring. The operator can rotate the rotating disk 242 to adjust the angle of the stirring component 25 according to the area distribution inside the machine body 1, so that the stirring component 25 can fully stir the anti-wrinkle finishing liquid in the corner area of ​​the machine body 1, eliminate stirring blind spots, and further improve the uniformity of stirring. At the same time, after stirring, by adjusting the height and rotation angle of the stirring component 25, the stirring component 25 does not obstruct the space on the machine body 1.

[0040] The pressing unit 3 includes two hinge seats 33 fixedly connected to the top of the body 1 and two bearing blocks 32 hinged in the hinge seats 33. The two bearing blocks 32 are fixedly connected to a bearing plate 31 at the end away from the hinge seats 33. A support rod 37 is slidably connected to the top of the bearing plate 31. A filter plate 34 is fixedly connected to the bottom of the support rod 37. Multiple round rods 38 are fixedly connected to the side of the filter plate 34 away from the body 1. A limit bolt 36 is threadedly connected to one side of the bearing plate 31. The end of the limit bolt 36 passes through the bearing plate 31 and extends into the movable hole to abut against the outer surface of the support rod 37. A magnetic column 35 is fixedly connected to the end of the filter plate 34 away from the support rod 37.

[0041] The hinge seat 33 cooperates with the support block 32, allowing the support plate 31 to be flipped open for easy placement and removal of the four-sided elastic fabric. The support rod 37 can slide through the support plate 31 to adjust the pressing height of the filter plate 34. The limit bolt 36 can firmly lock the support rod 37 to ensure that the filter plate 34 presses down on the four-sided elastic fabric stably. The round rod 38 on the filter plate 34 can prevent the four-sided elastic fabric from floating and ensure that the four-sided elastic fabric is fully immersed in the anti-wrinkle finishing liquid. The magnetic column 35 at the bottom of the filter plate 34 can be magnetically attracted to the magnet 50 of the fabric lifting unit 5, making it easy to remove the filter plate 34 and the four-sided elastic fabric together. The pressing unit 3 can precisely control the immersion depth and soaking time of the four-sided elastic fabric to avoid insufficient local soaking and improve the anti-wrinkle treatment effect.

[0042] The drying unit 4 includes a support platform 44 fixedly connected to the side of the body 1 and a mounting box 42 fixedly connected to the top of the support platform 44. Multiple heating tubes 45 are fixedly connected inside the mounting box 42. A fan 43 is fixedly connected to the side of the mounting box 42 away from the body 1. The fan 43 is connected to the mounting box 42. An air outlet 41 is fixedly connected to the side of the mounting box 42 near the body 1. The air outlet 41 penetrates the body 1 and extends into the body 1. Multiple heat conduction holes are opened on the air outlet 41. A height limit plate 46 is fixedly connected to the lower part of the end of the air outlet 41 away from the mounting box 42.

[0043] The support platform 44 provides stable support for the mounting box 42. The heating tube 45 can heat the air. The fan 43 sends the hot air into the air outlet 41. Multiple heat conduction holes on the air outlet 41 make the hot air blow evenly to the elastic cloth on all four sides, achieving rapid drying. The height limit plate 46 serves to indicate the liquid level inside the machine body 1.

[0044] The fabric lifting unit 5 includes two positioning blocks 54 inserted and connected to the bottom of the machine body 1 and two positioning plates 51 fixedly connected to the top of the two positioning blocks 54. Each of the two positioning plates 51 has a connecting ring 53 fixedly connected to its top. A magnet 50 is fixedly connected to the bottom of the connecting ring 53. The magnet 50 is magnetically attracted to the magnetic column 35 of the pressing unit 3. Multiple crossbars 52 are fixedly connected between the two positioning plates 51.

[0045] The positioning block 54 can be firmly inserted into the bottom of the machine body 1 to ensure the stable installation of the cloth lifting unit 5. The multiple crossbars 52 between the two positioning plates 51 can support the four-sided elastic cloth and prevent the four-sided elastic cloth from being deformed due to gravity during the removal process. The magnet 50 in the connecting ring 53 and the magnetic column 35 of the pressing unit 3 magnetically attract each other, which can adsorb and lift the filter plate 34 and the four-sided elastic cloth together, making it easy for operators to quickly remove the processed four-sided elastic cloth. The cloth lifting unit 5 has a simple structure and is easy to use, and can effectively protect the four-sided elastic cloth from damage during the removal process.

[0046] The draining unit 6 includes a drain pipe 63 fixedly connected to the drain port (not shown in the figure, the drain port is used to drain the anti-wrinkle finishing liquid in the body 1) and a valve 65 fixedly connected to the outer surface of the drain pipe 63. A filter pipe 61 is threadedly connected to the end of the drain pipe 63 away from the body 1. Filter screens 64 are fixedly connected inside both the filter pipe 61 and the drain pipe 63. Protrusions 62 distributed in a ring are fixedly connected to the outer surface of the filter pipe 61.

[0047] The drain pipe 63 is used to discharge the anti-wrinkle finishing liquid after use. The valve 65 can control the drainage speed and start / stop. The filter pipe 61 is threadedly connected to the drain pipe 63 for easy disassembly and cleaning. The double-layer filter screen 64 inside the filter pipe 61 and the drain pipe 63 can effectively filter fabric fibers, impurities, etc. in the waste liquid to prevent pipe blockage and facilitate waste liquid recycling. The protrusions 62 on the outer surface of the filter pipe 61 increase the friction force, making it easier for operators to turn the filter pipe 61. This drain unit 6 has both filtration and discharge functions.

[0048] When using, pour the prepared finishing liquid into the machine body 1. Before stirring, adjust the position and angle of the stirring component 25: Start the first reduction motor 229 in the moving component 22. The output end of the first reduction motor 229 drives the screw 224 in the base 223 to rotate. When the screw 224 rotates, it will drive the outer shell 227, the top rod 228, the rotating platform 24 above, and the stirring component 25 to slide horizontally along the slide rail 222 until the stirring component 25 moves to the initial stirring area inside the machine body 1; then start the second reduction motor 231 in the drive component 23, the first reduction motor 229... The second geared motor 231 drives the drive rod 233 and the drive gear 234 at its end to rotate through its output end. The drive gear 234 meshes with the tooth groove 220 on the outer surface of the push rod 228, converting the rotational motion into the vertical lifting motion of the push rod 228. The push rod 228 drives the rotating platform 24 and the stirring assembly 25 to rise and fall synchronously, adjusting the height of the stirring assembly 25 so that the stirring component 258 is immersed in the anti-wrinkle finishing liquid. Then, the rotating disk 242 is manually rotated. The rotating disk 242 can be flexibly adjusted in angle. After the stirring assembly 25 is adjusted to the preset stirring angle, the limit block 243 is... The pin 244 is inserted into the corresponding hole 240 on the outer surface of the rotating disk 242 to lock the rotation angle. If it is necessary to adjust the front and back position of the agitator, the telescopic cylinder 252 in the agitator assembly 25 is activated. The telescopic cylinder 252 drives the support plate 255 to move back and forth, adjusting the position of the agitator 258. After the adjustment is completed, the third reduction motor 254 is activated. The third reduction motor 254 drives the connecting rod 256 to rotate. The agitator 258, which is fixed by the connecting bolt 257, rotates synchronously. The locking block 2581 of the agitator 258 drives the triangular plate 2583 to rotate. Multiple stirring rods 2584 and the arc-shaped baffles on the outer surface stir the anti-wrinkle finishing liquid. The irregular column 2585 in the center breaks the laminar flow state and enhances the turbulence effect. During the stirring process, the first reduction motor 229 can be restarted to drive the stirring component 25 to move horizontally along the slide rail 222, so as to realize the all-round stirring of the anti-wrinkle finishing liquid inside the machine body 1 and ensure that the components of the anti-wrinkle finishing liquid are evenly mixed. After the stirring is completed, the stirring unit 2 is recycled by reversing the steps to reduce the space occupied in the machine body 1. If necessary, the stirring component 258 can be removed and the stirring unit 2 can be completely rotated and recycled back into the machine body 1.

[0049] Lay the four-sided elastic fabric to be treated flat on the crossbar 52 of the fabric lifting unit 5, flip the bearing plate 31, slide the support rod 37 to adjust the height of the filter plate 34, and press down the pressing unit 3 to make the four-sided elastic fabric completely immersed in the anti-wrinkle finishing liquid in the machine body 1. Tighten the limit bolt 36 to lock the position. After soaking for a certain period of time, loosen the limit bolt 36 counterclockwise to release the lock on the support rod 37. Manually pull the support rod 37 upward. The support rod 37 drives the filter plate 34 and the fabric lifting unit 5, which is magnetically connected to the magnetic column 35, to move upward. Multiple crossbars 52 lift the four-sided elastic fabric until the four-sided elastic fabric... The fabric rises above the surface of the anti-wrinkle finishing liquid, at which point the four-sided elastic fabric is in a liquid-free state. Then, the drying unit 4 is activated: the heating tube 45 is turned on, and the fan 43 is started at the same time. The fan 43 sends the hot air in the mounting box 42 into the air outlet 41. The hot air is evenly dispersed through multiple heat conduction holes on the air outlet 41 and blown onto the surface of the four-sided elastic fabric. Since the drying unit 4 is provided on both sides of the machine body 1, the hot air is blown onto the four-sided elastic fabric from both sides at the same time, achieving all-round and uniform drying. After the four-sided elastic fabric is completely dried and shaped, the heating tube 45 and the fan 43 are turned off and the four-sided elastic fabric is taken out.

[0050] Repeat the above steps for repeated soaking and drying. When waste liquid needs to be discharged, open the valve 65 on the outer surface of the drain pipe 63. The used anti-wrinkle finishing liquid in the machine body 1 flows into the drain pipe 63 through the drain outlet. It first passes through the filter screen 64 in the drain pipe 63 for the first filtration to remove larger particles of impurities and fabric fibers. Then the waste liquid flows into the filter pipe 61, which is threaded to the drain pipe 63. It then passes through the filter screen 64 in the filter pipe 61 for the second fine filtration to further purify the waste liquid. The pore size of the filter screen 64 in the filter pipe 61 is smaller than that of the filter screen 64 in the drain pipe 63. The filtered waste liquid is discharged from the end of the filter pipe 61 and can be directly recycled or discharged in compliance with standards. During regular maintenance, the operator can hold the annular protrusion 62 on the outer surface of the filter pipe 61 and rotate the filter pipe 61 counterclockwise to separate the filter pipe 61 from the drain pipe 63, making it easier to clean or replace the two filter screens 64 and prevent clogging from affecting the drainage efficiency.

[0051] A method for preventing wrinkles in four-way stretch fabric, employing the aforementioned composite treatment device for preventing wrinkles in four-way stretch fabric, includes the following steps: S1. Pretreatment: Conduct an appearance inspection on the four-way stretch fabric, and measure the fabric width and weight parameters; soak the four-way stretch fabric in clean water at 30℃~40℃ for 15 minutes~20 minutes, and then gently rinse it 2 to 3 times in a washing machine at a speed of 100 rpm~200 rpm. S2. Pre-setting: Place the cleaned four-way stretch fabric into the tenter frame, set the temperature to 180℃~190℃, and the speed to 20m / min~30m / min for pre-setting. S3. Prepare finishing solution raw materials: Prepare 3% to 5% of the total finishing solution raw materials, silicone softener, 8% to 12% of dimethyloldihydroxyvinyl urea anti-wrinkle finishing agent, 0.5% to 1% of magnesium chloride catalyst, 0.2% to 0.5% of penetrant and the balance water. S4. Composite treatment: Pour the finishing liquid raw material prepared in step S3 into the four-way stretch fabric anti-wrinkle composite treatment device. The four-way stretch fabric anti-wrinkle composite treatment device is continuously stirred for 30 to 40 minutes to make an anti-wrinkle finishing liquid. The four-way stretch fabric that has been pre-shaped in step S2 is sent into the four-way stretch fabric anti-wrinkle composite treatment device to fully immerse the fabric in the anti-wrinkle finishing liquid for more than 20 minutes. Then, the soaked four-way stretch fabric is dried by the four-way stretch fabric anti-wrinkle composite treatment device. S5. Post-treatment: Put the dried four-way stretch fabric into a washing machine, add an appropriate amount of neutral detergent at 40℃~50℃ and wash for 15 minutes~20 minutes. Then, after dehydrating the four-way stretch fabric, put it into a dryer and dry at 80℃~90℃ for 20 minutes~30 minutes. S6. Quality Inspection: Check whether the surface of the treated four-way stretch fabric is flat and free from defects such as wrinkles, color spots, and color variations.

[0052] In step S3, the formulation simultaneously uses a silicone softener accounting for 3% to 5% of the total raw materials of the finishing liquid and a dimethyloldihydroxyethylene urea anti-wrinkle finishing agent accounting for 8% to 12% of the total raw materials of the finishing liquid. In textile chemical industry, silicone softeners are lightweight and easily demulsify to form floating oil, while high-concentration anti-wrinkle resins are heavy and easily settle to the bottom. Traditional stirring makes it extremely difficult to maintain the uniformity of the composite liquid. By continuously stirring for 30 to 40 minutes in step S4, the composite liquid can be uniformly stirred using the stirring element 258 in the above-mentioned four-sided elastic fabric anti-wrinkle composite treatment device.

[0053] Because four-way stretch fabric is rich in spandex, it has a large liquid absorption capacity. If traditional manual transfer to other dryers is used after 20 minutes of soaking in step S4, gravity will cause the finishing liquid to flow violently downwards on the fabric surface, which is a common migration phenomenon in the dyeing and finishing industry. This results in excessive hardness at the bottom of the fabric and failure of anti-wrinkle properties at the top. This process utilizes the magnetic attraction of the fabric lifting unit 5 in the four-way stretch fabric anti-wrinkle composite treatment device to steadily lift the fabric to a liquid-free state. Without moving the physical coordinates of the fabric, the drying units 4 on both sides of the machine body 1 are activated instantly. Hot air is blown onto the fabric through the bidirectional air outlet 41, so that the moisture of dimethyloldihydroxyethylene urea is rapidly evaporated in situ and cross-linked and solidified inside the fibers before migration occurs, ensuring the absolute consistency of anti-wrinkle effect, softness and weight of the entire fabric.

[0054] In step S2, a high-temperature pre-forming process at 180℃~190℃ is used, which not only stabilizes the dimensions of the four-way stretch fabric, but also fully opens the microscopic capillaries of the spandex and polyester or cotton fibers. Next, the pre-treated fabric is fed into a highly homogenized finishing liquid containing 0.2%~0.5% penetrant, which is broken up by the strong turbulence equipment of the four-way stretch fabric anti-wrinkle composite treatment device. The open fiber pores and the microemulsion of the finishing liquid with extremely small particle size combine instantly, and the magnesium chloride catalyst can penetrate deep into the fiber core, which greatly improves the cross-linking depth of the anti-wrinkle resin. This allows the final product to maintain its long-lasting, wash-resistant anti-wrinkle performance after washing in step S5, and has a full hand feel and excellent resilience.
