Description

Technical Field

[0001] This invention relates to the field of fabric dyeing, and more particularly to a fabric dyeing apparatus and method for garment production. Background Technology

[0002] In the garment manufacturing process, fabric dyeing is a crucial step, directly determining the final garment's key quality characteristics such as color, luster, uniformity, and hand feel. The quality of dyeing not only affects the product's market competitiveness but also the consumer's wearing experience. Therefore, efficient, uniform, environmentally friendly dyeing technologies and equipment capable of meeting diverse color requirements have always been a key focus of research and development in the textile and apparel industry. Currently, widely used fabric dyeing equipment in the industry mainly includes overflow dyeing machines, jet dyeing machines, roll dyeing machines, and some continuous dyeing equipment.

[0003] Existing dyeing equipment, especially traditional hanging dyeing methods, can easily lead to uneven dyeing depths in different parts of the fabric (such as the edges and center, the upper and lower parts). This is mainly because the fabric is suspended under gravity, resulting in uneven contact area and contact time with the dye liquor, making it difficult to ensure the uniformity of the overall dyeing effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fabric dyeing apparatus and method for garment production, thus solving the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fabric dyeing apparatus for garment production, comprising:

[0006] Fabric dyeing pool; the fabric dyeing pool is equipped with multiple multi-stage dyeing tanks;

[0007] A dye liquor detection mechanism is installed on the upper surface of the fabric dyeing pool.

[0009] Preferably, the number of support arms is set to six, with two support arms respectively fixedly connected to the left and right sides of the upper surface of the fabric dyeing pool. A fixing plate is fixedly connected to the inner side of the upper end of each support arm. A drive motor is fixedly connected to the upper surface of the fixing plate. The output end of the drive motor is driven by a drive screw. The lower end of the drive screw is rotatably connected to the upper surface of the fabric dyeing pool. A threaded lifting frame is threadedly connected to the outer surface of the drive screw. The outer end of the threaded lifting frame is slidably connected to the inner side of the limiting slide rail. The limiting slide rail is fixedly connected to the inner side of the support arm. A connecting rod is fixedly connected to the lower surface of the threaded lifting frame away from the limiting slide rail. The lower end of the connecting rod is fixedly connected to the upper surface of the fixing ring. A fabric pressure roller is transversely arranged through the middle of the fixing ring. A lifting plate is fixedly connected to the end of the threaded lifting frame away from the limiting slide rail. A dye liquor detector is fixedly connected to the upper surface of the lifting plate. A detection rod is arranged on the lower surface of the dye liquor detector. The lower end of the detection rod passes through the lifting plate and is fixedly connected to a dye liquor detection head.

[0010] Preferably, three dye bath tanks are provided in front of the fabric dyeing pool, and two pH adjustment cylinders are provided on the upper surface of each dye bath tank. A liquid pump is provided between the dye bath tank and the pH adjustment cylinder and the fabric dyeing pool.

[0011] Preferably, the waste treatment mechanism includes a connecting arm, a positioning frame, an adsorption hood, an air guide pipe, a blower, an exhaust pipe, a waste gas-liquid treatment box, a liquid suction pump, a liquid guide pipe, a liquid discharge pipe, and a sealing plug. The front and rear ends of the connecting arm are fixedly connected to the inner sides of two support arms. The positioning frame is fixedly connected to the inner side of the connecting arm, and the adsorption hood is fixedly connected to the inner side of the positioning frame. The adsorption hood is positioned above the fabric dyeing pool.

[0012] Preferably, an exhaust fan is installed inside the adsorption hood, and the exhaust end of the exhaust fan is connected to a duct. The duct is installed on the upper surface of the adsorption hood, and the end of the duct away from the exhaust end of the exhaust fan passes through the interior of the waste gas-liquid treatment box. The waste gas-liquid treatment box is located behind the fabric dyeing pool.

[0013] Preferably, the waste gas-liquid treatment box is provided with multiple liquid guide pipes on the side near the fabric dyeing tank. The end of the liquid guide pipe away from the waste gas-liquid treatment box is connected to a liquid suction pump. The discharge end of the liquid suction pump is connected to the liquid guide pipe. The suction end of the liquid suction pump is located inside the multi-stage dyeing tank.

[0014] Preferably, the upper surface of the multi-stage dyeing tank is provided with two guide rollers, the front and rear ends of which are rotatably connected to the front and rear sides inside the fabric dyeing tank, and a garment fabric is provided between the two guide rollers and the fabric pressure roller.

[0015] Preferably, the fabric dyeing pool is fixedly connected to fixed brackets at both the front and rear ends on the left side, and a guide roller rotates between the two fixed brackets. A guide motor is provided on the outside of the fixed brackets, and the output end of the guide motor is connected to the guide roller for transmission.

[0016] Preferably, a liquid guide tube is fixedly connected to one side of the fabric dyeing pool, and a sealing plug is threaded to the end of the liquid guide tube away from the fabric dyeing pool.

[0017] A fabric dyeing method for garment production includes the following steps:

[0018] Step 1: Fabric introduction and guidance: The garment fabric is first sent into the fabric dyeing tank. Before entering the multi-stage dyeing tank area, it will pass through two guide rollers set above the dyeing tank. These rollers are responsible for initially guiding the fabric so that its path is aligned with the area where the fabric pressure rollers will form a V-shaped structure.

[0019] Step 2: V-shaped structure formation and dyeing: When dyeing is required, the drive motor starts and drives the drive screw to rotate. Through thread engagement, the thread lifting frame moves downward and drives the fabric pressure roller to press down onto the garment fabric via the connecting rod and the fixing ring. Since the pressure roller usually acts on the middle of the fabric, the two sides of the fabric naturally tilt to the sides and downward, forming a V-shaped distribution in the dye bath.

[0020] Step 3: Real-time detection and automatic control of dye liquor: While the fabric pressure roller is pressing down, the lifting plate connected to it also drives the dye liquor detection head to descend to the appropriate dye liquor depth. The dye liquor detection head monitors the parameters of the dye liquor in real time. The liquid pump works automatically according to the signal from the detection head to replenish the dyeing pool or adjust the pH value of the dye liquor through the pH adjustment cylinder to maintain the stability of the dye liquor parameters and ensure the dyeing quality.

[0021] Step 4: Waste gas extraction and waste liquid collection: During the dyeing process, the exhaust fan of the waste treatment mechanism is started to extract the waste gas containing dye volatiles, auxiliary agent vapors, etc. from the opening of the adsorption hood set above the fabric dyeing tank. The waste gas is then introduced into the waste gas-liquid treatment tank through the air guide pipe. At the same time, the liquid suction pump is started to extract the waste liquid containing residual dyes, auxiliaries and impurities from the multi-stage dyeing tank and pump it into the waste gas-liquid treatment tank through the liquid guide pipe.

[0022] Beneficial effects

[0023] This invention provides a fabric dyeing apparatus and method for garment production. Compared with the prior art, it has the following advantages:

[0024] 1. In this invention, through the dye liquor detection mechanism, the garment fabric is first sent into the fabric dyeing tank. Before entering the multi-stage dyeing tank area, the fabric passes through two guide rollers set above the dyeing tank. When the garment fabric needs to be immersed in the dye liquor, the drive motor starts, and its output end drives the drive screw to rotate. The drive screw and the threaded lifting frame are engaged by threads. When the drive screw rotates clockwise (or counterclockwise, depending on the thread direction), the threaded lifting frame moves downward along the screw. When the threaded lifting frame moves downward, the fabric pressure roller also moves downward through the connecting rod and the fixing ring. The fabric pressure roller presses down onto the garment fabric, pressing it downward into the dye liquor in the multi-stage dyeing tank. Since the point of action of the pressure roller is usually in the middle of the fabric, the fabric naturally tilts to the sides and downwards while being pressed down, thus forming a V-shaped distribution in the dye liquor. Compared with traditional hanging dyeing, the V-shaped structure allows the fabric to have a larger and more uniform contact area with the dye liquor at the same time. This reduces the problem of uneven dyeing between the edges and center, and between the upper and lower parts caused by gravity suspension, greatly improving the overall dyeing uniformity. While the threaded lifting frame descends, its other end is also fixedly connected to a lifting plate. The lifting plate is equipped with a dye liquor detector and its detection rod and dye liquor detection head below it. Therefore, the dye liquor detection head will descend with the fabric pressure roller to the appropriate dye liquor depth for detection. The dye liquor detection head monitors the state of the dye liquor in real time (such as temperature, concentration, pH value). The liquid pump works automatically according to the signal of the dye liquor detection head to replenish the dye liquor to the dyeing pool or adjust the pH value of the dye liquor to maintain the stability of the dye liquor parameters. This garment production fabric dyeing device realizes the precise downward pressure of the fabric pressure roller on the garment fabric through the precision mechanical structure driven by the drive screw, forcibly forming a V-shaped structure that is conducive to uniform dyeing. Combined with real-time dye liquor detection and automatic control, it provides a modern dyeing solution that is efficient, uniform, intelligent and highly adaptable.

[0025] 2. In this invention, through the waste treatment mechanism, during the dyeing process, waste gas containing pollutants such as dye volatiles and auxiliary agent vapors is generated above and behind the fabric dyeing tank. When the exhaust fan is started, it draws the waste gas generated above the dyeing tank from the opening of the adsorption hood. The waste gas drawn in by the exhaust fan enters the connected air guide pipe through its exhaust end and is introduced into the waste gas-liquid treatment tank. During the dyeing process, waste liquid containing residual dyes, auxiliaries, and impurities is generated in the multi-stage dyeing tank. When the liquid suction pump is started, it draws the waste liquid from the bottom of the multi-stage dyeing tank or a designated position, and then through the liquid suction end, pump body, and liquid guide pipe to discharge the waste liquid. The liquid is pumped into the waste gas-liquid treatment tank and merged with the waste gas delivered by the exhaust fan. Some soluble volatile organic compounds (VOCs) in the waste gas will dissolve or be absorbed into the waste liquid. Acidic waste gas can neutralize alkaline substances in the waste liquid. Some volatile substances in the waste gas can be directly absorbed by the waste liquid, while some chemical components in the waste liquid can react with the waste gas, achieving a synergistic purification effect of "treating waste with waste". The liquid after mixed treatment is enriched with absorbents from the waste gas and useful components from the waste liquid. This part of the liquid can be further recycled, purified or centrally treated as a resource, improving resource utilization. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-9 The present invention provides two technical solutions, specifically including the following embodiments:

[0039] Example 1:

[0040] A fabric dyeing device for garment production includes: a fabric dyeing pool 1; multiple multi-stage dyeing tanks 2 are arranged inside the fabric dyeing pool 1; a dye liquor detection mechanism 3; the dye liquor detection mechanism 3 is disposed on the upper surface of the fabric dyeing pool 1, and is used to simultaneously detect the dye liquor in the fabric dyeing pool 1 and to ensure that the garment fabric 8 is distributed in a V-shape in the dye liquor of the multi-stage dyeing tanks 2; the dye liquor detection mechanism 3 includes a support arm 301, a fixing plate 302, a drive screw 303, a threaded lifting frame 304, a limiting slide rail 305, a connecting rod 306, a fixing ring 307, a fabric pressure roller 308, a lifting plate 309, and a dyeing... The dye liquor detector 310, detector rod 311, dye liquor detector head 312, and drive motor 313 are included. Six support arms 301 are provided, with two opposite support arms 301 fixedly connected to the left and right sides of the upper surface of the fabric dyeing pool 1, respectively. A fixing plate 302 is fixedly connected to the inner side of the upper end of each support arm 301. A drive motor 313 is fixedly connected to the upper surface of the fixing plate 302. A drive screw 303 is driven to the output end of the drive motor 313. The lower end of the drive screw 303 is rotatably connected to the upper surface of the fabric dyeing pool 1. A threaded lifting frame 304 is threadedly connected to the outer surface of the drive screw 303. The outer end of the lifting frame 304 is slidably connected to the inner side of the limiting slide rail 305. The limiting slide rail 305 is fixedly connected to the inner side of the support arm 301. A connecting rod 306 is fixedly connected to the lower surface of the end of the threaded lifting frame 304 away from the limiting slide rail 305. The lower end of the connecting rod 306 is fixedly connected to the upper surface of the fixing ring 307. A fabric pressure roller 308 is transversely arranged through the middle of the fixing ring 307. A lifting plate 309 is fixedly connected to the end of the threaded lifting frame 304 away from the limiting slide rail 305. A dye liquor detector 310 is fixedly connected to the upper surface of the lifting plate 309. A detection rod 3 is arranged on the lower surface of the dye liquor detector 310. 11. The lower end of the detection rod 311 passes through the lifting plate 309 and is fixedly connected to the dye liquor detection head 312. Three dye liquor tanks 10 are set on the front side of the fabric dyeing pool 1. Each dye liquor tank 10 is equipped with two pH adjustment cylinders 11 on its upper surface. A liquid pump is set between the dye liquor tank 10 and the pH adjustment cylinder 11 and the fabric dyeing pool 1. Each liquid pump is electrically connected to the dye liquor detection head 312. Two guide rollers 9 are set on the upper surface of the multi-stage dyeing tank 2. The front and rear ends of the guide rollers 9 are rotatably connected to the front and rear sides inside the fabric dyeing pool 1. Garment fabric 8 is set between the two guide rollers 9 and the fabric pressure roller 308.

[0041] During operation, the garment fabric 8 is first fed into the fabric dyeing tank 1. Before entering the multi-stage dyeing tank 2 area, the fabric passes through two guide rollers 9 set above the dyeing tank. When it is necessary to immerse the garment fabric 8 in the dye solution, the drive motor 313 starts, and its output end drives the drive screw 303 to rotate. The drive screw 303 is engaged with the threaded lifting frame 304 through threads. When the drive screw 303 rotates clockwise or counterclockwise, depending on the thread direction, the threaded lifting frame 304 moves downward along the screw. When the lifting frame 304 moves downward, the fabric pressure roller 308 also moves downward through the connecting rod 306 and the fixing ring 307. The fabric pressure roller 308 presses down onto the garment fabric 8, pressing it downward into the dye liquor in the multi-stage dyeing tank 2. Since the point of action of the pressure roller is usually in the middle of the fabric, the fabric naturally tilts to the sides and downwards as it is pressed down, thus forming a V-shaped distribution in the dye liquor. Compared with traditional hanging dyeing, the V-shaped structure allows the fabric to have a larger and more uniform contact area with the dye liquor at the same time, reducing the impact of weight. The uneven dyeing caused by force suspension at the edges and center, and at the top and bottom, is greatly improved, significantly enhancing the overall dyeing uniformity. As the threaded lifting frame 304 descends, its other end is fixedly connected to a lifting plate 309. The lifting plate 309 is equipped with a dye liquor detector 310, a detection rod 311 below it, and a dye liquor detection head 312. Therefore, the dye liquor detection head 312 descends with the fabric pressure roller 308 to the appropriate dye liquor depth for detection. The dye liquor detection head 312 monitors the state of the dye liquor in real time, such as temperature, concentration, and pH value. The liquid pump automatically operates based on the signal from the dye liquor detection head 312, replenishing the dye liquor to the dyeing pool or adjusting the pH value to maintain stable dye liquor parameters. This garment production fabric dyeing device, through a precision mechanical structure driven by the drive screw 303, achieves precise downward pressure of the fabric pressure roller 308 on the garment fabric 8, forcibly forming a V-shaped structure conducive to uniform dyeing. Combined with real-time dye liquor detection and automatic control, it provides a highly efficient, uniform, intelligent, and adaptable modern dyeing solution.

[0042] Example 2:

[0043] Based on Embodiment 1, a waste treatment mechanism 4 is provided. The waste treatment mechanism 4 is located above and behind the fabric dyeing tank 1. It is used to treat waste gas and waste liquid generated during the dyeing process. The waste treatment mechanism 4 includes a connecting arm 401, a positioning frame 402, an adsorption hood 403, a gas guide pipe 404, a blower 405, an exhaust pipe 406, a waste gas and liquid treatment tank 407, a liquid suction pump 408, a liquid guide pipe 409, a drain pipe 410, and a sealing plug 411. The connecting arm 401 is fixedly connected to the inner sides of two support arms 301 at both ends. A positioning frame 402 is fixedly connected to the inner side of the connecting arm 401, and an adsorption hood 403 is fixedly connected to the inner side of the positioning frame 402. The adsorption hood 403 is located above the fabric dyeing tank 1, and a suction pump is installed inside the adsorption hood 403. The exhaust end of the blower 405 is connected to a guide pipe 404, which is located on the upper surface of the adsorption hood 403. The end of the guide pipe 404 furthest from the exhaust end of the blower 405 extends through the interior of the waste gas-liquid treatment box 407, which is located behind the fabric dyeing tank 1. Multiple liquid guide pipes 409 are located on the side of the waste gas-liquid treatment box 407 closest to the fabric dyeing tank 1. A liquid suction pump 408 is connected to the end of each liquid guide pipe 409 furthest from the waste gas-liquid treatment box 407. The discharge end of the liquid suction pump 408 is connected to the liquid guide pipe 409, and the suction end of the liquid suction pump 408 is located inside the multi-stage dyeing tank 2. Fixed supports 6 are fixedly connected to both the front and rear ends of the left side of the fabric dyeing tank 1, and a guide roller 5 rotates between the two fixed supports 6. A guide motor 7 is installed on the outside of the fixed bracket 6. The output end of the guide motor 7 is connected to the guide roller 5. A liquid guide pipe 409 is fixedly connected to one side of the fabric dyeing tank 1. A sealing plug 411 is threaded to the end of the liquid guide pipe 409 away from the fabric dyeing tank 1. During the dyeing process, waste gas containing pollutants such as dye volatiles and auxiliary agent vapors will be generated above and behind the fabric dyeing tank 1. When the exhaust fan 405 is started, it will draw the waste gas generated above the dyeing tank from the opening of the adsorption hood 403. The waste gas drawn in by the exhaust fan 405 enters the connected air guide pipe 404 through its exhaust end and is introduced into the waste gas liquid treatment box 407. During the dyeing process, waste liquid containing residual dyes, auxiliaries and impurities will be generated in the multi-stage dyeing tank 2. When the liquid suction pump 408 is started... It draws waste liquid from the bottom or a designated location of the multi-stage dyeing tank 2, and pumps it through the suction end and pump body, and then through the liquid guide pipe 409 into the waste gas-liquid treatment tank 407 to merge with the waste gas sent by the exhaust fan 405. Some soluble volatile organic compounds (VOCs) in the waste gas will dissolve or be absorbed into the waste liquid. Acidic waste gas can neutralize alkaline substances in the waste liquid. Some volatile substances in the waste gas can be directly absorbed by the waste liquid, while some chemical components in the waste liquid can react with the waste gas, achieving a synergistic purification effect of "treating waste with waste". The liquid after mixed treatment is enriched with absorbents from the waste gas and useful components from the waste liquid. This part of the liquid can be further recycled, purified or centrally treated as a resource, improving resource utilization.

[0044] A fabric dyeing method for garment production includes the following steps:

[0045] Step 1: Fabric introduction and guidance: The garment fabric 8 is first sent into the fabric dyeing pool 1. Before entering the multi-stage dyeing tank 2 area, it will pass through two guide rollers 9 set above the dyeing tank. These rollers are responsible for initially guiding the fabric so that its path is aligned with the area where the fabric pressure roller 308 forms a V-shaped structure.

[0046] Step 2: V-shaped structure formation and dyeing: When dyeing is required, the drive motor 313 starts, driving the drive screw 303 to rotate. Through thread engagement, the thread lifting frame 304 moves downward and drives the fabric pressure roller 308 to press down onto the garment fabric 8 via the connecting rod 306 and the fixing ring 307. Since the pressure roller usually acts on the middle of the fabric, the two sides of the fabric naturally tilt to the sides and downward, forming a V-shaped distribution in the dye bath.

[0047] Step 3: Real-time detection and automatic control of dye liquor: While the fabric pressure roller 308 is pressing down, the lifting plate 309 connected to it also drives the dye liquor detection head 312 to descend to the appropriate dye liquor depth. The dye liquor detection head 312 monitors the parameters of the dye liquor in real time. The liquid pump works automatically according to the signal from the detection head to replenish the dyeing pool or adjust the pH value of the dye liquor through the pH adjustment cylinder 11 to maintain the stability of the dye liquor parameters and ensure the dyeing quality.

[0048] Step 4: Waste gas extraction and waste liquid collection: During the dyeing process, the exhaust fan 405 of the waste treatment mechanism 4 is started to extract the waste gas containing dye volatiles, auxiliary agent vapors, etc. from the opening of the adsorption hood 403 located above and behind the fabric dyeing tank 1, and introduce the waste gas into the waste gas-liquid treatment tank 407 through the air guide pipe 404. At the same time, the liquid suction pump 408 is started to extract the waste liquid containing residual dyes, auxiliaries and impurities from the multi-stage dyeing tank 2, and pump it into the waste gas-liquid treatment tank 407 through the liquid guide pipe 409.

5. A fabric dyeing apparatus for garment production according to claim 4, characterized in that: The waste gas-liquid treatment box (407) is provided with multiple liquid guide pipes (409) on the side near the fabric dyeing tank (1). The end of the liquid guide pipe (409) away from the waste gas-liquid treatment box (407) is connected to a liquid suction pump (408). The discharge end of the liquid suction pump (408) is connected to the liquid guide pipe (409). The suction end of the liquid suction pump (408) is located inside the multi-stage dyeing tank (2).

6. A fabric dyeing apparatus for garment production according to claim 5, characterized in that: The fabric dyeing pool (1) is fixedly connected to the front and rear ends of the left side with fixed brackets (6), and a guide roller (5) rotates between the two fixed brackets (6). A guide motor (7) is provided on the outside of the fixed bracket (6), and the output end of the guide motor (7) is connected to the guide roller (5) for transmission.

7. A fabric dyeing apparatus for garment production according to claim 6, characterized in that: A liquid guide tube (409) is fixedly connected to one side of the fabric dyeing pool (1), and a sealing plug (411) is threaded to the end of the liquid guide tube (409) away from the fabric dyeing pool (1).

8. A fabric dyeing method for garment production, based on the fabric dyeing apparatus for garment production as described in claim 7, characterized in that: Includes the following steps: Step 1: Fabric introduction and guidance: The garment fabric (8) is first sent into the fabric dyeing pool (1). Before entering the multi-stage dyeing tank (2) area, it will pass through two guide rollers (9) set above the dyeing tank. These rollers are responsible for initially guiding the fabric so that its path is aligned with the area where the fabric pressure roller (308) forms a V-shaped structure. Step 2: V-shaped structure formation and dyeing: When dyeing is required, the drive motor (313) starts and drives the drive screw (303) to rotate. Through thread engagement, the thread lifting frame (304) moves downward and drives the fabric pressure roller (308) to press down onto the garment fabric (8) via the connecting rod (306) and the fixing ring (307). Since the pressure roller usually acts on the middle of the fabric, the two sides of the fabric naturally tilt to the sides and downward, forming a V-shaped distribution in the dye bath. Step 3: Real-time detection and automatic control of dye liquor: While the fabric pressure roller (308) is pressing down, the lifting plate (309) connected to it also drives the dye liquor detection head (312) to descend to the appropriate dye liquor depth. The dye liquor detection head (312) monitors the parameters of the dye liquor in real time. The liquid pump works automatically according to the signal from the detection head to replenish the dyeing pool or adjust the pH value of the dye liquor through the pH adjustment cylinder (11) to maintain the stability of the dye liquor parameters and ensure the dyeing quality. Step 4: Waste gas extraction and waste liquid collection: During the dyeing process, the exhaust fan (405) of the waste treatment mechanism (4) is started to extract the waste gas containing dye volatiles and auxiliary agent vapors from the opening of the adsorption hood (403) set above the fabric dyeing tank (1) and introduce the waste gas into the waste gas-liquid treatment tank (407) through the air guide pipe (404). At the same time, the liquid suction pump (408) is started to extract the waste liquid containing residual dyes, auxiliary agents and impurities from the multi-stage dyeing tank (2) and pump it into the waste gas-liquid treatment tank (407) through the liquid guide pipe (409).
