Description

Technical Field

[0001] The present invention relates to the field of fabric dyeing, and in particular to a fabric dyeing device and method for garment production. Background Art

[0002] Fabric dyeing is a crucial step in the garment manufacturing process, directly determining key quality characteristics of the finished garment, including color, gloss, uniformity, and feel. Dyeing quality not only impacts the product's market competitiveness but also the consumer's wearing experience. Therefore, dyeing technologies and equipment that are efficient, uniform, environmentally friendly, and capable of meeting diverse color requirements have been a focus of ongoing research and development within the textile and apparel industry. Currently, widely used fabric dyeing equipment includes overflow dyeing machines, jet dyeing machines, jigger dyeing machines, and some continuous dyeing equipment.

[0003] Existing dyeing devices, especially the traditional hanging dyeing method, easily lead to different shades of dyeing in different parts of the fabric (such as the edge and center, top and bottom).

The inner side of the connecting arm is fixedly connected to the positioning frame, and the inner side of the positioning frame is fixedly connected to the adsorption hood.

[0013] Preferably, a plurality of liquid guide tubes are provided on the side of the waste gas and liquid treatment box close to the fabric dyeing tank, and a liquid suction pump is connected to one end of the liquid guide tube away from the waste gas and liquid treatment box, the discharge end of the liquid suction pump and the liquid guide tube are interconnected, and the liquid suction end of the liquid suction pump is arranged inside the multi-stage dyeing tank.

[0014] Preferably, two guide rollers are provided on the upper surface of the multi-stage dyeing tank, and the front and rear ends of the guide rollers are rotatably connected to the front and rear sides of the fabric dyeing tank, and clothing fabrics are provided between the two guide rollers and the fabric pressing roller.

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

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

[0018] Step 1: Fabric Introduction and Guidance: The garment fabric is first fed into the fabric dyeing tank. Before entering the multi-stage dyeing tank area, it passes over two guide rollers installed above the dyeing tank. These rollers are responsible for the initial guidance of the fabric, aligning its path with the area where the fabric pressing rollers will form a V-shaped structure.

[0019] Step 2: V-shaped structure formation and dyeing: When dyeing is required, the drive motor starts, driving the drive screw to rotate. Through the thread engagement, the threaded lifting frame moves downward, and drives the fabric pressing roller to press down on the garment fabric through the connecting rod and fixed ring. Since the pressing 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 solution;

[0020] Step 3: Real-time detection and automatic control of dye liquor: As the fabric pressing roller presses 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 automatically works according to the signal from the detection head to replenish dye liquor to the dyeing tank or adjust the pH value of the dye liquor through the pH adjustment cylinder to maintain the stability of dye liquor parameters and ensure 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 vapor, etc. from the opening of the adsorption hood set on the upper and rear side of the fabric dyeing tank, and introduce the waste gas into the waste gas and liquid treatment box through the air duct. At the same time, the suction pump is started to extract the waste liquid containing residual dyes, auxiliary agents and impurities from the inside of the multi-stage dyeing tank, and pump it into the waste gas and liquid treatment box through the liquid duct.

[0022] Beneficial effects

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

[0024] 1. In the present invention, the clothing fabric is first sent into the fabric dyeing tank through the dye liquid detection mechanism. Before entering the multi-stage dyeing tank area, the fabric will pass through two guide rollers arranged above the dyeing tank. When the clothing fabric needs to be immersed in the dye liquid, the drive motor is started, and its output end drives the drive screw to rotate. The drive screw and the threaded lifting frame are engaged through threads. When the drive screw rotates clockwise (or counterclockwise, depending on the direction of the thread), the threaded lifting frame will move downward along the screw. When the threaded lifting frame moves downward, the fabric pressure roller also moves downward through the connecting rod and the fixed ring. The fabric pressure roller presses down on the clothing fabric and presses it downward into the dye liquid in the multi-stage dyeing tank. Since the action point of the pressure roller is usually in the middle of the fabric, the two sides of the fabric naturally tilt to the sides and downward while being pressed down, thereby forming a V-shaped distribution in the dye liquid. Compared with traditional hanging dyeing, the V-shaped structure allows the fabric to have a larger and more uniform area to contact the dye liquid at the same time. , reduces the problem of uneven dyeing between the edge and center, and between the upper and lower parts due to gravity suspension, and greatly improves the overall dyeing uniformity. While the threaded lifting frame descends, its other end is fixedly connected to the lifting plate, on which the dye liquid detector and the detection rod and dye liquid detection head below it are installed. Therefore, the dye liquid detection head will descend to the appropriate dye liquid depth for detection along with the fabric pressure roller. The dye liquid detection head monitors the state of the dye liquid (such as temperature, concentration, pH value) in real time. The liquid pump automatically works according to the signal of the dye liquid detection head to replenish dye liquid to the dyeing tank or adjust the pH value of the dye liquid to maintain the stability of the dye liquid parameters. The 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 driving screw, forcing the formation of a V-shaped structure that is conducive to uniform dyeing, and combines real-time dye liquid detection and automatic control to provide an efficient, uniform, intelligent and adaptable modern dyeing solution;

[0025] 2. In the present invention, by setting up the waste material treatment mechanism, during the dyeing process, waste gas containing pollutants such as dye volatiles and auxiliary agent vapor will be generated on the upper rear side of the fabric dyeing tank. When the exhaust fan is started, it will extract the waste gas generated above the dyeing tank from the opening of the adsorption cover. The waste gas sucked by the exhaust fan passes through its exhaust end, enters the connected air duct and is introduced into the waste gas liquid treatment box. During the dyeing process, waste liquid containing residual dye, auxiliary agent and impurities will be generated in the multi-stage dyeing tank. When the liquid suction pump is started, it will extract the waste liquid from the bottom of the multi-stage dyeing tank or a designated position, pass through the liquid suction end, the pump body, and then through the liquid duct to discharge the waste liquid. The liquid is pumped into the waste gas-liquid treatment box and merged with the waste gas sent by the exhaust fan. Some soluble volatile organic compounds (VOCs) in the waste gas will dissolve or be absorbed into the waste liquid. The acidic waste gas can react with the alkaline substances in the waste liquid to neutralize. Some volatile substances in the waste gas can be directly absorbed by the waste liquid, and some chemical components in the waste liquid can react with the waste gas, realizing the synergistic purification effect of "treating waste with waste". The mixed liquid is enriched with the absorbents from the waste gas and the useful components in the waste liquid. This part of the liquid can be further recovered, purified or centrally treated as a resource, thereby improving resource utilization. BRIEF DESCRIPTION OF THE DRAWINGS

10. A fabric dyeing method for garment production, based on the fabric dyeing device for garment production according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Fabric introduction and guidance: The garment fabric (8) is first fed into the fabric dyeing tank (1). Before entering the multi-stage dyeing tank (2), it passes through two guide rollers (9) arranged above the dyeing tank. These rollers are responsible for initially guiding the fabric so that its path is aligned with the area where the V-shaped structure is subsequently formed by the fabric pressing roller (308); Step 2: V-shaped structure formation and dyeing: When dyeing is required, the drive motor (313) is started, driving the drive screw (303) to rotate, and the threaded lifting frame (304) moves downward through the thread engagement, and drives the fabric pressing roller (308) to press down on the clothing fabric (8) through the connecting rod (306) and the fixed ring (307). Since the pressing 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 solution; Step 3: Real-time detection and automatic control of dye liquor: When the fabric pressing roller (308) is pressed down, the lifting plate (309) connected to it also drives the dye liquor detection head (312) to descend to a suitable dye liquor depth. The dye liquor detection head (312) monitors the parameters of the dye liquor in real time. The liquid pump automatically works according to the signal of the detection head to replenish the dye liquor to the dyeing tank 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 material treatment mechanism (4) is started to extract the waste gas containing dye volatiles, auxiliary agent vapors, etc. from the opening of the adsorption cover (403) set on the upper rear side of the fabric dyeing tank (1), and introduce the waste gas into the waste gas and liquid treatment box (407) through the air guide pipe (404). At the same time, the suction pump (408) is started to extract the waste liquid containing residual dye, auxiliary agent and impurities from the inside of the multi-stage dyeing tank (2), and pump it into the waste gas and liquid treatment box (407) through the liquid guide pipe (409).
