Abstract
Description
Technical Field
[0001] This invention relates to the field of dyeing and finishing equipment technology, specifically to intelligent dyeing and finishing equipment and dyeing and finishing processes for Tencel-linen blended woven fabrics. Background Technology
[0002] Tencel-linen blended woven fabric is a new type of fabric made by blending and weaving Tencel fibers with linen fibers. It combines the softness and smoothness of Tencel and its good drape with the crispness, breathability, antibacterial and mildew-proof properties of linen fibers. It is widely used in high-end clothing, home textiles and other fields.
[0003] Reference patent (CN223674919U) discloses a dyeing and finishing equipment for fabric dyeing, including a dyeing box. A control panel is installed on the front surface of the dyeing box, and a top cover is installed inside the dyeing box. From left to right, an inlet trough and an outlet trough are sequentially formed on the upper surface of the top cover. An outlet frame is installed inside the outlet trough, and an inclined block is installed on one side of the inner wall of the outlet frame. An inclined plate is installed on the outer surface of the inclined block, and an electric push rod is installed on the other side of the inner wall of the outlet trough. Because the contact surface between the inclined block and the inclined extrusion plate is inclined, the inclined extrusion plate effectively extrudes the fabric, and excess dye falls downwards after extrusion without affecting the already extruded fabric. Simultaneously, the inclined plate can scrape off excess fabric from the surface, resulting in a good overall effect of extruding and draining the dye after dyeing.
[0004] Based on the aforementioned patent, hemp fiber has high crystallinity and a tight molecular arrangement. Furthermore, the fiber surface is covered with pectin and lignin, making dye penetration difficult. Air bubbles easily accumulate in the fiber gaps, hindering dye molecules from entering the fiber interior, resulting in shallow dyeing and poor colorfastness. While Tencel fiber has good hygroscopicity and is easy to dye, its dense cortex structure causes rapid dye adsorption upon contact with the dye solution. If not properly controlled, this can easily lead to "ring dyeing," where the fiber surface is deeply dyed while internal penetration is insufficient, resulting in a significant color difference between the inside and outside, affecting the overall dyeing effect. Moreover, Tencel fiber has extremely strong hygroscopicity. In traditional dyeing and finishing processes, if Tencel-hemp blended woven fabric is directly immersed in the dye vat, the Tencel fiber will rapidly absorb a large amount of dye, leading to excessively deep surface dyeing and insufficient internal dye penetration, forming a "ring dyeing" phenomenon, i.e., a color difference between the inside and outside. Therefore, this invention provides an intelligent dyeing and finishing equipment and process for Tencel-hemp blended woven fabric. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides intelligent dyeing and finishing equipment and processes for Tencel-linen blended woven fabrics. It solves the problem that in traditional dyeing and finishing processes, if the Tencel-linen blended woven fabric is directly immersed in the dye vat, the Tencel fibers will quickly absorb a large amount of dye, resulting in excessively dark surface dyeing and insufficient internal dye penetration, forming a "ring dyeing" phenomenon, i.e., color difference between the inside and outside.

The spray assembly includes a dye liquor tank fixed to one side of the dye liquor shell, a spray pipe connected to the upper end of the dye liquor tank via a flow assembly, spray nozzles evenly distributed on the lower end face of the spray pipe, and a sealing pipe connected to the spray pipe via a push assembly inside the spray pipe.
[0007] Preferably, a second bevel gear is fixed to the lower end of the vertical shaft, and a first shell is fixed to the lower end of the dye liquor shell. The first shell has a drive shaft driven by a motor inside, and a first bevel gear is fixed to one end of the drive shaft. The first bevel gear and the second bevel gear are meshed together.
[0008] Preferably, a second outer shell is fixed to both ends of the lower end face of the dye liquor shell. A drive shaft is horizontally rotatably connected inside the second outer shell. A worm gear shaft is fixed to one end of the drive shaft, and a worm is fixed to the lower end of the vertical shaft. The worm and the worm gear shaft are meshed together. A drive disk is fixed to the other end of the drive shaft. A movable rod connected to the edge of the drive disk is provided through a rotating shaft. The other end of the movable rod is connected to a vertical rod through a rotating shaft. The vertical rod is slidably connected to the dye liquor shell, and the disturbance plate is fixedly connected to the vertical rod.
[0009] Preferably, an installation plate is provided on the outer side of the dye liquor shell, and a take-up roller is provided on the upper end face of the installation plate on both sides of the dye liquor shell. A guide roller is provided on one side of the take-up roller, and the guide roller is used to guide the fabric between the spray pipes.
[0010] Preferably, the flow assembly includes a conduit body connected to the upper end of the dye bath via a pump body, one end of the conduit body is connected to a connector, the spray pipe is located at the lower end of the connector, and there are two sets of spray pipes distributed vertically.
[0011] Preferably, the push assembly includes an L-shaped bracket fixed on both sides of the dye liquor shell, a third electric push rod fixed horizontally on the L-shaped bracket, a fixed plate fixed to the telescopic end of the third electric push rod, and a sealing tube fixedly connected to one side of the fixed plate.
[0012] Preferably, the dye liquid shell is provided with downwardly inclined drainage shells on both sides, and the drainage shells are located below the spray pipe.
[0013] Preferably, a fixing bracket is fixed to the rear side wall of the dye liquor shell, a first electric push rod is fixed to the upper end of the fixing bracket, a connecting shell is fixed to the lower end of the first electric push rod, a shock-absorbing spring is fixed to the lower end of the connecting shell, a connecting block is fixed to the lower end of the shock-absorbing spring, a damping support rod is provided in the inner ring of the shock-absorbing spring and the damping support rod is fixedly connected to the connecting shell, the connecting block is slidably connected to the connecting shell, a connecting plate is fixed to the lower end of the connecting block, a first tensioning roller frame is provided on both sides of the connecting plate, a telescopic sleeve rod is fixed to the edge of the connecting shell, and one end of the telescopic sleeve rod is fixedly connected to the connecting block.
[0014] This invention also provides an intelligent dyeing and finishing process for Tencel-linen blended woven fabrics, comprising the following steps: Step 1: The fabric is released from the take-up roller and guided into the spray pipes through the guide roller. The dye liquor is evenly sprayed on both sides for pretreatment. Excess dye liquor is recovered through the drain shell. Step 2: The pre-treated fabric enters the upper part of the dye bath shell. The first electric push rod drives the pressing mechanism to immerse the fabric in the dye bath after buffering, and the tension is adjusted by the tension roller. Step 3: During the dyeing process, the motor drives the spiral fan blades to generate a spiral upward liquid flow, while the disturbance plate swings up and down to form a composite flow field, which promotes the penetration of the dye solution and uniform coloring.
[0015] This invention provides intelligent dyeing and finishing equipment and processes for Tencel-linen blended woven fabrics. Compared with existing technologies, it has the following advantages: Firstly, this invention utilizes the meshing transmission of the first and second bevel gears to drive the stirring bracket and the spiral fan blades to form a vortex, causing the dye liquor to flow upwards in a spiral shape. This ensures thorough mixing of the dye liquor while preventing it from directly impacting the Tencel-linen blended woven fabric, thus preventing fabric damage or uneven dyeing. The disturbance plate swings up and down within the slide rail bracket, working in conjunction with the spiral dye liquor flow, essentially providing micro-vibration "assisted turning" from below the fabric. This ensures that the front and back sides and the middle layer of the Tencel-linen blended fabric can evenly contact the dye liquor, while simultaneously dislodging air bubbles from the gaps in the linen fibers, preventing them from hindering dye liquor penetration and solving the problem of difficult linen fiber penetration. The micro-vortex formed by the micro-vibration can remove the floating dye from the Tencel surface, preventing color differences between the inside and outside caused by Tencel being saturated with dye first. At the same time, the combination of spiral stirring and up-and-down disturbance further improves the contact efficiency between the dye liquor and the fabric, ensuring dyeing uniformity.
[0016] Secondly, this invention uses spray nozzles to uniformly pre-treat the fabric, which can pre-wet the Tencel-linen blended fabric and avoid uneven dyeing caused by localized drying after the fabric enters the dye bath. This allows the dye bath to "forcefully" wet the surface and gaps of the linen fibers, opening the fiber's immersion channels in advance and laying the foundation for deep penetration during subsequent main dyeing. Tencel fibers are highly hygroscopic; if directly immersed in the dye vat, they will quickly absorb a large amount of dye, easily leading to a "ring dyeing" phenomenon where the surface is deeply dyed but the interior is not penetrated, i.e., color difference between the inside and outside. The spray pre-treatment allows both Tencel and linen fibers to uniformly absorb a portion of the dye bath first, balancing the dyeing rates of both, thereby effectively reducing floating dye and color difference between the inside and outside of Tencel, resulting in a more uniform dyeing effect and more stable color. At the same time, the third electric push rod drives the sealing tube to move, adjusting the spray range of the spray tube, which can be adapted to Tencel-linen blended woven fabrics of different widths, improving the versatility of the equipment.

[0019] 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.
[0020] Please see Figures 1 to 10 The present invention provides the following two technical solutions. First embodiment: Intelligent dyeing and finishing equipment for Tencel-linen blended woven fabric, including a dye liquor shell 1, on which an installation mechanism for dyeing and finishing Tencel-linen blended woven fabric is provided, the installation mechanism including: The mixing assembly includes a vertical shaft 303 disposed inside the dye liquor shell 1, a stirring bracket 305 fixed at the upper end of the vertical shaft 303, a support plate 306 disposed on the outer side of the stirring bracket 305, cylindrical through holes 307 fixed on the surface of the support plate 306, a spiral fan blade 308 fixed inside the cylindrical through holes 307, and slide rail brackets 407 fixed on both sides of the dye liquor shell 1, with multiple sets of disturbance plates 408 slidably connected inside the slide rail brackets 407. The spray assembly includes a dye liquor tank 7 fixed to one side of the dye liquor shell 1. A spray pipe 703 connected to the upper end of the dye liquor tank 7 via a flow assembly is provided. Spray nozzles 704 are evenly distributed on the lower end face of the spray pipe 703. A sealing pipe 708 connected to the spray pipe 703 via a push assembly is provided inside the spray pipe 703.
[0021] In this embodiment of the invention, a second bevel gear 304 is fixed to the lower end of the vertical shaft 303, and a first outer shell 3 is fixed to the lower end of the dye liquor shell 1. A drive shaft 301 driven by a motor is provided inside the first outer shell 3. A first bevel gear 302 is fixed to one end of the drive shaft 301. The first bevel gear 302 and the second bevel gear 304 are meshed and connected to drive the rotation of the stirring bracket 305, so that the liquid is driven upward and passes through the spiral fan blade 308, ensuring that the dye liquor is spiraled upward, avoiding direct impact on the dyeing cloth, and without weakening the stirring effect.
[0022] Specifically, inside the first outer shell 3 at the lower end of the dye liquor shell 1, the drive shaft 301 is driven to rotate by a motor. The first bevel gear 302 at one end of the drive shaft 301 meshes with the second bevel gear 304 at the lower end of the vertical shaft 303, driving the vertical shaft 303 to rotate synchronously, thereby rotating the stirring bracket 305. The rotation of the stirring bracket 305 can drive the dye liquor upward, passing through the spiral fan blade 308 to form a spiral upward liquid flow, which not only ensures that the dye liquor is fully mixed, but also avoids the dye liquor directly impacting the Tencel-linen blended woven fabric.
[0023] In this embodiment of the invention, a second outer shell 4 is fixed to both ends of the lower end face of the dye liquor shell 1. A transmission shaft 401 is horizontally rotatably connected inside the second outer shell 4. A worm gear shaft 402 is fixed to one end of the transmission shaft 401, and a worm 403 is fixed to the lower end of the vertical shaft 303. The worm 403 and the worm gear shaft 402 are meshed together. A transmission disk 404 is fixed to the other end of the transmission shaft 401. A movable rod 405 connected to the edge of the transmission disk 404 via a rotating shaft is provided. A vertical rod 406 is connected to the other end of the movable rod 405 via a rotating shaft. The vertical rod 406 is slidably connected to the dye liquor shell 1, and a disturbance plate 408 is fixedly connected to the vertical rod 406. While stirring, the disturbance plate 408 is driven to swing up and down. Combined with the spiral flow of stirring, it is equivalent to using micro-vibration to "assist turning" the fabric from below, so that the front and back sides and the middle layer of the fabric can be evenly contacted with the dye liquor. The air bubbles in the gaps of the hemp fibers are more easily shaken out, and the floating dye on the surface of Tencel can also be carried away by the micro-vortex.
[0024] Specifically, the worm gear 403 fixed at the lower end of the vertical shaft 303 meshes with the worm wheel shaft 402 at one end of the transmission shaft 401 inside the second housing 4, causing the transmission shaft 401 to rotate. The transmission disk 404 at the other end of the transmission shaft 401 rotates, and its edge drives the vertical rod 406 to slide up and down through the movable rod 405 connected by the rotating shaft. This, in turn, drives the disturbance plate 408 fixedly connected to the vertical rod 406 to swing up and down inside the slide rail bracket 407. This, together with the spiral dye liquor, forms a composite flow field, creating a micro-vibration environment. The vibration helps to break the static liquid film and air bubbles between the gaps in the hemp fibers, allowing the dye liquor to penetrate deeper into the hemp fibers more easily.
[0025] The second embodiment differs from the first embodiment in that: a mounting plate 2 is provided on the outer side of the dye liquor shell 1; a take-up roller 201 is provided on both sides of the upper end of the mounting plate 2 on the dye liquor shell 1; a guide roller 202 is provided on one side of the take-up roller 201, and the guide roller 202 is used to guide the fabric between the spray pipes 703; the flow assembly includes a conduit body 701 connected to the upper end of the dye liquor tank 7 via a pump body; one end of the conduit body 701 is connected to a connecting joint 702; the spray pipes 703 are located at the lower end of the connecting joint 702; and two sets of spray pipes 703 are distributed vertically; the pushing assembly includes the dye liquor shell. 1. An L-shaped bracket 705 is fixed on both sides. A third electric push rod 706 is fixed horizontally on the L-shaped bracket 705. A fixing plate 707 is fixed to the telescopic end of the third electric push rod 706. A sealing tube 708 is fixedly connected to one side of the fixing plate 707. Inclined downward drainage shells 8 are provided on both sides of the dye liquor shell 1. The drainage shells 8 are located below the spray pipe 703 and are used for spraying to pre-treat the dye. This addresses the problem of difficult penetration of hemp fibers and easy floating of Tencel fibers when dyeing Tencel-linen blended woven fabrics. Water is easily trapped in the gaps of hemp fibers, so the dye liquor does not penetrate deeply. Tencel may absorb the dye first, resulting in color difference between the inside and outside.
[0026] Specifically, the upper end of the dye bath 7 is connected to the conduit body 701 via the pump body. One end of the conduit body 701 is connected to the connector 702. The spray pipe 703 is located below the connector 702. The dye bath enters the spray pipe 703 through the conduit body 701 and the connector 702. The spray nozzles 704, which are evenly distributed on the lower end face of the spray pipe 703, spray the dye liquor evenly onto the surface of the Tencel-linen blended woven fabric to perform dyeing pretreatment on the fabric. The third electric push rod 706, which is horizontally fixed on the L-shaped brackets 705 on both sides of the dye liquor shell 1, extends and retracts, causing the fixed plate 707 fixed at its extension end to move. This, in turn, causes the sealing tube 708, which is fixedly connected to the fixed plate 707, to move inside the spray pipe 703, adjusting the spray range of the spray pipe 703 to adapt to fabrics of different widths. The downward-sloping drainage shell 8 below the spray pipe 703 drains and recycles the excess dye liquor after spraying, avoiding waste of dye liquor.
[0027] In this embodiment of the invention, a fixing bracket 5 is fixed to the rear side wall of the dye liquor shell 1. A first electric push rod 501 is fixed to the upper end of the fixing bracket 5, and a connecting shell 502 is fixed to the lower end of the first electric push rod 501. A shock-absorbing spring 503 is fixed to the lower end of the connecting shell 502, and a connecting block 505 is fixed to the lower end of the shock-absorbing spring 503. A damping support rod 504 is provided on the inner ring of the shock-absorbing spring 503, and the damping support rod 504 is fixedly connected to the connecting shell 502. The connecting block 505 is connected to the connecting shell 502. 02 is slidably connected. The lower end of the connecting block 505 is fixed with a connecting plate 506. The two sides of the connecting plate 506 are provided with a first tension roller frame 6. The edge of the connecting shell 502 is fixed with a telescopic sleeve rod 507. One end of the telescopic sleeve rod 507 is fixedly connected to the connecting block 505. The center of the connecting plate 506 is provided with a second electric push rod 601. The lower end of the second electric push rod 601 is provided with a second tension roller frame 602, which is used to press the pre-treated sprayed dyed cloth into the dye shell 1 for immersion.
[0028] Specifically, the take-up roller 201 on the upper end of the mounting plate 2 on the outer side of the dye liquor shell 1 releases the Tencel-linen blended woven fabric, and the guide roller 202 guides the fabric between the upper and lower spray pipes 703 to achieve continuous fabric conveying. After pretreatment, the fabric enters the upper part of the dye liquor shell 1. The first electric push rod 501 on the fixed bracket 5 extends, driving the connecting shell 502 to move downward. The connecting shell 502 drives the connecting block 505 and the connecting plate 506 to move downward through the shock-absorbing spring 503 and the damping support rod 504. The first tensioning roller frame 6 on both sides of the connecting plate 506 and the second tensioning roller frame 602 driven by the second electric push rod 601 at the center press the fabric down into the dye liquor of the dye liquor shell 1 to achieve immersion dyeing. The shock-absorbing spring 503 and the damping support rod 504 play a shock-absorbing role to prevent damage to the fabric during the pressing process. The telescopic sleeve rod 507 ensures that the connecting block 505 slides smoothly. The second electric push rod 601 adjusts the height of the second tensioning roller frame 602 to ensure that the fabric tension is appropriate and improve the dyeing effect.
[0029] This invention also provides an intelligent dyeing and finishing process for Tencel-linen blended woven fabrics, including the following steps: Step 1: The fabric is released from the take-up roller 201 and introduced into the spray pipe 703 through the guide roller 202. The dye liquor is evenly sprayed on both sides for pretreatment. Excess dye liquor is recovered through the drainage shell 8. Step 2: The pre-treated fabric enters the dye bath shell 1. The first electric push rod 501 drives the pressing mechanism to immerse the fabric in the dye bath after buffering, and the tension is adjusted by the tension roller. Step 3: During the dyeing process, the motor drives the spiral fan blades 308 to generate a spiral upward liquid flow. Simultaneously, the disturbance plate 408 oscillates up and down to form a composite flow field, promoting dye penetration and uniform coloring. Specifically, inside the first outer shell 3 at the lower end of the dye liquor shell 1, the motor drives the drive shaft 301 to rotate. The first bevel gear 302 at one end of the drive shaft 301 meshes with the second bevel gear 304 at the lower end of the vertical shaft 303, causing the vertical shaft 303 to rotate synchronously. This rotation of the stirring support 305 allows the dye liquor to rise upwards. Driven by the spiral fan blades 308, the liquid flows upward in a spiral. The worm gear 403 fixed at the lower end of the vertical shaft 303 meshes with the worm wheel shaft 402 at one end of the transmission shaft 401 inside the second housing 4, causing the transmission shaft 401 to rotate. The transmission disk 404 at the other end of the transmission shaft 401 rotates, and its edge drives the vertical rod 406 to slide up and down through the movable rod 405 connected by the rotating shaft. This, in turn, drives the disturbance plate 408 fixedly connected to the vertical rod 406 to swing up and down inside the slide rail bracket 407, forming a composite flow field in conjunction with the spiral dye liquid.
[0030] The aforementioned drive shaft 301 and take-up roller shaft 201 use OEMER_LQ225L three-phase liquid-cooled variable frequency motors, the electric push rods use DT-1600-400 electric push rods, and the pump body uses 80FBZ-22 type acid and alkali resistant self-priming pumps. All models are suitable for the corrosion resistance and dye liquor erosion prevention requirements of Tencel and linen blend dyeing and finishing, avoiding damage to electrical components due to contact with dye liquor, and extending the service life of the equipment. This is existing technology and will not be elaborated further.
[0031] Working principle: The fabric is first released by the take-up roller 201 and guided by the guide roller 202 to the space between the upper and lower spray pipes 703; the dye liquid in the dye liquid tank 7 enters the spray pipe 703 through the pump body, the conduit body 701 and the connecting joint 702, and is evenly sprayed on both sides of the fabric by the spray nozzles 704 for pretreatment. At the same time, the third electric push rod 706 drives the fixing plate 707 to move the sealing pipe 708 to adjust the spray range. After spraying, the excess dye liquid is recovered by the drainage shell 8. After pretreatment, the fabric enters the upper part of the dye bath housing 1. The first electric push rod 501 pushes the connecting housing 502 downward. After being buffered by the shock-absorbing spring 503, the damping support rod 504, and the telescopic sleeve rod 507, the connecting block 505 and the connecting plate 506 are driven to descend, so that the first tensioning roller shaft 6 and the second tensioning roller shaft 602, whose height is adjusted by the second electric push rod 601, press the fabric down and immerse it in the dye bath. During the dyeing process, the motor drives the drive shaft 301 to rotate, and the first bevel gear 302 and the second bevel gear... The meshing of wheel 304 drives the vertical shaft 303 to rotate, causing the support plate 306 on the stirring bracket 305 and the internal spiral fan blades 308 to generate a spiral upward liquid flow. At the same time, the worm 403 at the lower end of the vertical shaft 303 drives the worm wheel shaft 402 to rotate the transmission shaft 401, which drives the transmission disc 404, the movable rod 405 and the vertical rod 406 to move. This causes the disturbance plate 408 in the slide rail bracket 407 to swing up and down, forming a composite flow field, ultimately achieving the effects of gentle stirring, deep penetration and uniform dyeing.
