Description

Technical Field

[0001] This invention relates to the field of fabric enzymatic technology, and in particular to a continuous enzymatic treatment device for Tencel fabrics. Background Technology

[0002] Tencel fiber is a regenerated cellulose fiber spun from wood pulp using N-methylmorpholine-N-oxide as a solvent. It possesses the comfort of cotton, the strength of polyester, the drape of viscose, and the feel of silk. However, Tencel fiber exhibits significant fibrillation characteristics, making it prone to fibrillation during wet processing. This characteristic can be used to achieve a peach-skin effect, but uneven fibrillation can also lead to quality problems.

[0003] Currently, the conventional process for achieving a peach-skin effect on Tencel fabrics is as follows: fabric turning and sewing → singeing → desizing and refining → mercerizing → fiber opening and enzyme washing → dyeing → defiberization treatment → stretching and finishing. Among these, the defiberization treatment is the key step. Traditionally, it is performed using industrial sand washing tanks for intermittent rope-like processing, which suffers from drawbacks such as low production efficiency, high labor intensity, easy crease formation, and inability to produce continuously. In recent years, however, air softeners have been introduced into the finishing of Tencel fabrics. These machines use airflow to drive the fabric in reciprocating motion, impacting a stainless steel mesh, thus combining physical beating with chemical enzyme treatment.

[0004] Regarding the aforementioned technologies, existing processing techniques have the following technical problems: Intermittent production: Traditional air softeners use rope-like intermittent processing, with the fabric moving back and forth in the chamber. The processing time for each batch is fixed, making continuous production impossible. After each batch is completed, the machine must be stopped to unload and reload, which prevents continuous operation and affects overall production efficiency.

[0005] The contradiction between enzyme reaction time and mechanical action time: Enzyme treatment requires a certain reaction time (usually 20-30 minutes), but prolonged mechanical beating can excessively damage the fabric structure, leading to decreased strength and excessive pilling. If the beating time is shortened, the enzyme reaction will be insufficient, resulting in a poor peach skin effect.

[0006] Although there are improved air softeners in the existing technology that use fan-shaped beating technology to change the original intermittent rope-like treatment to continuous fan-shaped beating, which improves the treatment effect and efficiency, they still cannot solve the contradiction between enzyme reaction time and mechanical action time. Summary of the Invention

[0007] In order to adapt the enzyme reaction time and mechanical action time in the enzyme treatment process of Tencel fabrics and realize continuous production, this application provides a continuous enzyme treatment device for Tencel fabrics.

[0008] This application provides a continuous enzyme treatment device for Tencel fabrics, which adopts the following technical solution: A continuous enzyme treatment device for Tencel fabric includes a feeding device for continuously moving the fabric along a preset direction, and further includes: The pretreatment box is located at the front end of the fabric conveying direction. A stacking conveyor belt is installed at the lower end of the pretreatment box. The pretreatment box is equipped with a stacking component for evenly stacking the fabric onto the stacking conveyor belt. When the stacking conveyor belt is working, it drives the stacked fabric to move slowly in the pretreatment box. The pretreatment box is also equipped with a spraying component. Before stacking, the fabric passes through the spraying component and is sprayed with an enzyme treatment liquid. The pretreatment box is also equipped with a temperature control module to control the internal temperature of the pretreatment box. The beating box is located behind the pretreatment box and has several support rollers arranged inside. The fabric is wrapped around all the support rollers in sequence and moves along the length direction. The beating box is equipped with several rotating beating elements for beating the fabric. The cleaning and unloading device is located at the end of the fabric conveying direction. It is used to clean the fabric after it has been beaten and to convey the fabric out of the conveying direction.

[0009] By adopting the above technical solution, the feeding device drives the fabric movement. After the fabric enters the pretreatment chamber, the enzymatic treatment liquid is sprayed onto the fabric by the spraying component. The pushing component evenly stacks the fabric on the stacking conveyor belt, allowing the conveyor belt to slowly move the fabric and fully react. After the reaction is complete, the fabric is sent into the beating chamber, where it is unfolded again under the support of the support rollers, facilitating mechanical beating by the beating elements. After beating, the fabric is sent to the washing and unloading device for washing, and then unloaded. The movement path of the enzymatic process within the pretreatment chamber is extended, thus allowing sufficient reaction time. This ensures that the enzymatic reaction time of the Tencel fabric is matched with the mechanical action time, which helps to achieve continuous production.

[0010] Optionally, the feeding device includes a placement frame and an unfolding assembly. One side of the placement frame is provided with a support arm for supporting the fabric material, and the placement frame is provided with a rotating traction roller. The fabric material is wound around the traction roller and unwound under the drive of the traction roller. The unfolding assembly includes several stretching rollers. The fabric material is in an unfolded state after being wound around all the stretching rollers in sequence.

[0011] By adopting the above technical solution, the placement frame supports and places the fabric raw material through the support arm, and the traction roller drives the fabric to continuously unwind and move. Multiple flattening rollers work together to stretch and pull the fabric, making it easier to spray the enzymatic reaction solution.

[0012] Optionally, the pretreatment box is also equipped with a rotating flattening roller. The fabric is wound around the flattening roller and rolled in connection with it. An arc-shaped plate is fixedly connected inside the pretreatment box. The arc-shaped plate is located outside the flattening roller. The fabric passes through the arc-shaped plate and the flattening roller. Two sets of spiral guide plates are fixedly connected to the side of the arc-shaped plate near the flattening roller. When the fabric passes through the spiral guide plates, it contacts the spiral guide plates. The spiral guide plates guide the fabric to flatten from the middle of the flattening roller to both ends.

[0013] By adopting the above technical solution, the flattening roller drives the fabric to move. Under the support of the arc plate, the two sets of spiral guide plates cooperate to flatten and guide the fabric, so that the fabric is stretched and unfolded from the middle to both sides, which helps to further reduce the wrinkles of the fabric and increase the contact area between the enzyme reaction solution and the fabric.

[0014] Optionally, the stacking assembly includes a swing arm and two limiting rollers. The swing arm is rotatably connected to the pretreatment box in a vertical direction. The pretreatment box is provided with a drive unit for driving the swing arm to swing back and forth. The two limiting rollers are parallel to each other and are located at the free-moving end of the swing arm. The fabric passes through the two limiting rollers and is in a vertical state. When the swing arm swings, it drives the fabric to continuously fold on the stacking conveyor belt through the limiting rollers.

[0015] By adopting the above technical solution, the driving component drives the swing arm to swing, so that the swing arm drives the fabric to swing back and forth through two limit rollers, thereby causing the fabric to fold and stack back and forth under the action of gravity.

[0016] Optionally, the stacking assembly further includes two fixed rollers and two clamping rollers. The two fixed rollers are parallel to each other and are fixedly connected to the pretreatment box. The fabric is folded between the two fixed rollers. The clamping rollers correspond one-to-one with the fixed rollers, and the two clamping rollers are located between the two fixed rollers. The pretreatment box is provided with a power component for driving the clamping rollers to swing radially. When the clamping rollers are close to the fixed rollers, they cooperate with the fixed rollers to clamp the fabric. When the clamping rollers are far away from the fixed rollers, they completely leave the area where the fabric is located.

[0017] By adopting the above technical solution, the power component drives the clamping roller to move. When the fabric approaches the fixed roller, the clamping roller approaches the fixed roller and clamps the fabric. At this time, the swing arm swings to the other side, causing the fabric to fold back. At this time, the fabric between the fixed roller and the clamping roller is at the crest of the crease. The two sets of clamping rollers alternately clamp and position the fabric, which helps to improve the folding uniformity of the fabric, thereby improving the enzymatic reaction effect.

[0018] Optionally, the pretreatment box is also equipped with a smoothing roller. The smoothing roller is located at the lower end of the fixed roller and is rotatably connected to the pretreatment box around its own axis. The pretreatment box is equipped with a rotating component for driving the smoothing roller to rotate. An elastic sheet is spirally arranged on the outer side of the smoothing roller in the circumferential direction. When the smoothing roller rotates, it drives the elastic sheet to flatten the folded fabric from top to bottom.

[0019] By adopting the above technical solution, when the rotating component drives the smoothing roller to rotate, the smoothing roller flattens the folded fabric through the elastic sheet, thereby improving the folding uniformity of the fabric.

[0020] Optionally, the stacking conveyor belt includes an arc-shaped section and a horizontal section. The arc-shaped section is located below the stacking assembly, and the horizontal section is located on the side of the arc-shaped section near the striking box. The pre-treatment box is fixedly connected to an arc-shaped limiting plate, which is located on the side of the arc-shaped section near its own center. The arc-shaped limiting plate and the arc-shaped section form a stacking cavity. The folded fabric is located in the stacking cavity and moves along the arc-shaped section to the horizontal section. During the movement, the folded fabric rotates from a vertical state to a horizontal state.

[0021] By adopting the above technical solution, the pretreatment box limits the stacking conveyor belt. After the fabric is folded, it falls on the arc-shaped part. At this time, the arc-shaped part supports the fabric, and the arc-shaped part cooperates with the arc-shaped limiting plate to limit the folded fabric. When the stacking conveyor belt is working, it drives the folded fabric to rotate from vertical to horizontal, thereby reducing the pressure of the upper fabric on the lower fabric, so that the fabric is evenly stressed, which helps to improve the reaction effect.

[0022] Optionally, a number of pushing blocks are arranged circumferentially on the outer side of the stacking conveyor belt. After the fabric is folded, it forms a uniform wave structure. During the operation of the stacking conveyor belt, the pushing blocks are inserted between two peaks of the fabric wave structure.

[0023] By adopting the above technical solution, the pusher block helps reduce the probability of slippage between the stacking conveyor belt and the fabric, and by separating the folded fabric with the pusher block, the reaction effect is improved.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Achieve continuous production: By using a stacked pretreatment to allow the fabric to fully react with the enzyme solution before entering the continuous beating treatment, the contradiction between enzyme reaction time and mechanical action time is resolved: the enzyme reaction process is decoupled from the mechanical beating process. The fabric is first placed in the pretreatment device to complete the enzyme reaction, and then enters the beating device for physical treatment. This avoids excessive damage to the fabric structure caused by prolonged beating, breaks the limitations of traditional intermittent production, realizes continuous operation of the entire line, and greatly improves production efficiency. 2. Uniform and stable treatment effect: The stacked reaction chamber allows the fabric to remain folded in a tension-free state, ensuring consistent reaction conditions in all parts of the fabric. 3. Improved fabric quality: The combination of sufficient enzyme reaction and appropriate mechanical action gives the fabric a uniform and delicate peach skin effect, with a soft and fluffy feel, excellent drape, and high strength retention. 4. Energy saving and consumption reduction: Continuous production reduces downtime and lowers energy consumption per unit output; 5. High degree of automation: Each module works in concert and can be integrated with a PLC control system to achieve automatic adjustment of process parameters and real-time monitoring of the production process.

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.

[0035] This application discloses a continuous enzyme treatment device for Tencel fabrics. Example

[0036] Reference Figure 1 and Figure 2 A continuous enzyme treatment device for Tencel fabric includes, in sequence along the fabric processing direction, a feeding device 1, a pretreatment box 2, a beating box 3, and a washing and unloading device 4. The feeding device 1 includes a placement frame 11 and an unfolding assembly. A support arm 111 is mounted on one side of the placement frame 11, and the support arm 111 is detachably connected to a rotating shaft for supporting the fabric raw material roll. Multiple parallel traction rollers 112 are also rotatably connected to the placement frame 11. The fabric is sequentially wound around all the traction rollers 112 and rolled in connection with them. A motor is also mounted on the placement frame 11 to drive any one of the traction rollers 112 to rotate. When the traction roller 112 rotates, it continuously unwinds the fabric raw material roll.

[0037] Reference Figure 1 and Figure 2 The unfolding assembly includes multiple stretch rollers 121, which are parallel to each other and rotatably connected to the placement frame 11 around their own axes. The fabric is sequentially wound around all the stretch rollers 121 and rolled in connection with them. All the stretch rollers 121 cooperate to keep the fabric taut, thereby allowing the fabric to unfold after unwinding. The pretreatment box 2 is hollow and made of heat-insulating material. A temperature control module is installed inside the pretreatment box 2 to control the temperature inside the pretreatment box 2.

[0038] Reference Figure 2 and Figure 3 The pretreatment chamber 2 has an inlet and an outlet for the fabric to pass through. The inlet is close to the placement rack 11, and the fabric enters the pretreatment chamber 2 through the inlet. The outlet is located at the end of the pretreatment chamber 2 away from the placement rack 11. Both the inlet and outlet have narrow diameters adapted to the fabric to reduce heat loss. A stacking conveyor belt 21 is installed inside the pretreatment chamber 2. The stacking conveyor belt 21 is located at the lower end of the pretreatment chamber 2 and includes an arc-shaped section 211 and a horizontal section 212. The arc-shaped section 211 is located near the inlet of the pretreatment chamber 2, and the horizontal section 212 is horizontally positioned and extends from the inlet to the outlet.

[0039] Reference Figure 2 and Figure 4The arc-shaped portion 211 extends upward from the horizontal portion 212 and eventually reaches a vertical position. Multiple shaping rollers 213 are installed inside the pretreatment box 2, arranged in an arc shape to support and shape the arc-shaped portion 211. An arc-shaped limiting plate 201 is fixedly connected inside the pretreatment box 2, located on the side of the arc-shaped portion 211 closest to its own center, forming a stacking cavity between the arc-shaped limiting plate 201 and the arc-shaped portion 211. Several pushing blocks 214 are evenly distributed circumferentially on the outer side of the stacking conveyor belt 21. The pushing blocks 214 are all made of elastic materials, such as rubber or silicone.

[0040] Reference Figure 2 and Figure 4 The pretreatment chamber 2 is also equipped with a flattening roller 24, which is rotatably connected to the pretreatment chamber 2 around its own axis. A tensioning roller parallel to the flattening roller 24 is also rotatably connected inside the pretreatment chamber 2. The fabric is sequentially wound around the flattening roller 24 and the tensioning roller and is in a tensioned state. Two opposing pull rollers are also rotatably connected inside the pretreatment chamber 2. After the fabric passes over the tensioning roller, it passes between the two pull rollers. When the pull rollers rotate, they pull the fabric through friction, thereby causing the fabric to move.

[0041] Reference Figure 4 and Figure 5 Pretreatment box 2 (reference) Figure 2 An arc-shaped plate 25 is fixedly connected to the fabric, located outside and coaxial with the flattening roller 24. The fabric passes between the arc-shaped plate 25 and the flattening roller 24. Two sets of opposing spiral guide plates 251 are fixedly connected to the side of the arc-shaped plate 25 closest to the flattening roller 24, extending from the middle to the ends of the arc-shaped plate 25. The spiral guide plates 251 are made of an elastic material, such as rubber. When the fabric passes between the arc-shaped plate 25 and the flattening roller 24, it contacts the spiral guide plates 251. As the fabric moves, the spiral guide plates 251 flatten the fabric from the middle to both ends, thereby further reducing wrinkles on the fabric.

[0042] Reference Figure 2 and Figure 4 Two sets of spraying assemblies 23 are installed inside the pretreatment chamber 2. Each spraying assembly 23 includes a spraying pipe and several nozzles. The two spraying pipes are parallel to each other, and the fabric passes between the two spraying pipes. The nozzles are evenly distributed on the side of the spraying pipes facing the fabric. A liquid supply tank 5 is installed on one side of the pretreatment chamber 2. The liquid supply tank 5 contains an enzyme reaction solution. A delivery pipe connects the liquid supply tank 5 to the spraying pipes, and the enzyme reaction solution is delivered to the spraying pipes through the delivery pipe. The enzyme reaction solution is sprayed from the nozzles onto the fabric, ensuring uniform contact between the fabric and the enzyme reaction solution.

[0043] Reference Figure 2 and Figure 6Inside the pretreatment chamber 2, a stacking assembly 22 is also provided. The stacking assembly 22 includes a swing arm 221 and two limiting rollers 222. The swing arm 221 is rotatably connected to the pretreatment chamber 2 in a vertical direction. The two limiting rollers 222 are parallel to each other and are both installed at the lower end of the swing arm 221. When the swing arm 221 moves, it drives the two limiting rollers 222 to move radially. The fabric passes between the two limiting rollers 222 and moves synchronously with the movement of the limiting rollers 222.

[0044] Reference Figure 2 and Figure 6 The pretreatment chamber 2 is equipped with a drive component 26 for reciprocating the swing arm 221. The drive component 26 includes a drive motor 261 and a turntable 262. The drive motor 261 is fixedly connected to the pretreatment chamber 2, and the turntable 262 is coaxially fixed to the output shaft of the drive motor 261. A movable rod 263 is fixedly connected to the turntable 262, and the movable rod 263 is eccentrically positioned relative to the axis of the turntable 262. The swing arm 221 has a groove 223 along its length, and the movable rod 263 is located within the groove 223 and is slidably connected to the swing arm 221 along the length of the groove 223. When the drive motor 261 drives the turntable 262 to rotate, the turntable 262 drives the swing arm 221 to reciprocate via the movable rod 263, causing the swing arm 221 to swing the limiting roller 222.

[0045] Reference Figure 6 and Figure 7 Under the influence of gravity, the fabric passes between the two limiting rollers 222 and moves towards the arc-shaped portion 211 of the stacking conveyor belt 21. When the swing arm 221 swings, it drives the fabric to move back and forth and fold back and forth. The stacking assembly 22 also includes two fixed rollers 224 and two clamping rollers 225. The fixed rollers 224 and clamping rollers 225 correspond one-to-one. The two fixed rollers 224 are parallel to each other and are fixedly connected to the pretreatment box 2. The swing range of the swing arm 221 is between the two fixed rollers 224.

[0046] Reference Figure 4 and Figure 7 Both clamping rollers 225 are positioned between two fixed rollers 224. The pretreatment box 2 is equipped with a power component 27 for moving the clamping rollers 225. The power component 27 includes a swing motor 271 and a swing rod 272. One end of the swing rod 272 is hinged to the pretreatment box 2, and the other end is hinged to the clamping rollers 225. There are two swing rods 272, which are parallel to each other. The two swing rods 272 cooperate to support and position the clamping rollers 225. During the swing of any swing rod 272, the clamping rollers 225 are moved, causing them to move closer to or away from the corresponding fixed rollers 224. The movement trajectory of the clamping rollers 225 is arc-shaped. The swing motor 271 is mounted on the pretreatment box 2 and is used to drive the swing rods 272 to swing.

[0047] Reference Figure 4 and Figure 7 Initially, the clamping roller 225 is away from the fixed roller 224. When the swing arm 221 moves the fabric closer to the fixed roller 224, the power component 27 moves the clamping roller 225 closer to the fixed roller 224, so that the clamping roller 225 and the fixed roller 224 cooperate to clamp and position the fabric. When the swing arm 221 moves the fabric to the other side, the lower end of the fabric is fixed by the fixed roller 224 and the clamping roller 225, so it is not easily deformed. When the fabric moves to another fixed roller 224, the other clamping roller 225 clamps the fabric again. At this time, the first set of clamping rollers 225 moves away from the corresponding fixed roller 224 again and completely leaves the area where the fabric is located, thereby releasing the clamping of the fabric. The fixed roller 224 and the clamping roller 225 cooperate to make the fabric form a wave crest structure, and all the wave crest structures are uniform in shape.

[0048] Reference Figure 4 and Figure 7 During the fabric folding process, the stacking conveyor belt 21 rotates continuously, causing the fabric to move slowly. When the clamping roller 225 moves away from the corresponding fixed roller 224, under the influence of gravity and the stacking conveyor belt 21, the fabric forming a wave crest detaches from between the fixed roller 224 and the clamping roller 225. This facilitates the cooperation between the fixed roller 224 and the clamping roller 225 to clamp and shape the next batch of fabric. The two sets of clamping rollers 225 and fixed rollers 224 work alternately to form a uniformly distributed wave crest structure, resulting in evenly stacked fabric, which helps improve the enzymatic reaction effect.

[0049] Reference Figure 3 and Figure 4 The folded fabric falls between the arc-shaped limiting plate 201 and the arc-shaped portion 211 of the stacking conveyor belt 21. The arc-shaped portion 211 and the arc-shaped limiting plate 201 cooperate to limit the fabric. When the stacking conveyor belt 21 is working, it drives the folded fabric to move towards the horizontal portion 212, so that the evenly folded fabric changes from a vertical state to a horizontal state, thereby reducing the probability that the fabric will be squeezed against each other under the action of gravity, resulting in excessive deformation of the creases and affecting the enzymatic reaction effect. Furthermore, when the stacking conveyor belt 21 is working, it drives the pushing block 214 to be inserted between two adjacent crests in sequence, thereby further separating and shaping the crests and reducing the probability of slippage between the stacking conveyor belt 21 and the fabric.

[0050] Reference Figure 3 and Figure 7Inside the pretreatment chamber 2, a smoothing roller 28 is also provided. The smoothing roller 28 is located below the fixed roller 224 and is parallel to the fixed roller 224. The pretreatment chamber 2 is equipped with a rotating component 29 for driving the smoothing roller 28 to rotate. Specifically, the rotating component 29 is a motor pulley assembly, which is existing technology and will not be described in detail here. Elastic sheets 281 are spirally arranged on the outer side of the smoothing roller 28. During the rotation of the smoothing roller 28, the elastic sheets 281 flatten the crests on the fabric that have initially detached from the clamping roller 225 from top to bottom, thereby smoothing out the deformation of the fabric caused by the movement of the clamping roller 225 when it moves away from the fabric, further improving the uniformity of fabric stacking.

[0051] Reference Figure 1 and Figure 8 The beating box 3 is located on the side of the pretreatment box 2 away from the placement frame 11, and multiple support rollers 31 are installed inside the beating box 3. The fabric enters the beating box 3 after being removed from the outlet of the pretreatment box 2. The beating box 3 is also made of heat-insulating material, and a temperature control system is also installed in the beating box 3 to regulate the internal temperature.

[0052] Reference Figure 1 and Figure 8 The fabric is sequentially wound around all the support rollers 31 inside the beating box 3. The beating box 3 contains beating elements 32, including a rotating roller and a fan-shaped beating plate. The rotating roller is rotatably mounted on the beating box 3, and a motor is installed inside the beating box 3 to drive the rotating roller. The fan-shaped beating plate is located on the outer surface of the rotating roller, and when the rotating roller rotates, it drives the fan-shaped beating plate to beating the fabric. The folded fabric moves slowly inside the pretreatment box 2. The conveying speed of the fabric inside the pretreatment box 2 is adjustable, ensuring consistent reaction conditions in all parts of the fabric. The enzymatic reaction time of the fabric is matched with the time required for mechanical beating. Furthermore, the speed at which the fabric enters or exits the pretreatment box 2 is matched with the speed required for beating, thereby achieving efficient continuous production.

[0053] Reference Figure 1 The washing and unloading device 4 includes a washing chamber and an unloading bracket. After leaving the beating chamber 3, the fabric enters the washing chamber. The washing chamber is equipped with a conveyor roller for moving the fabric, and a spray system is installed inside the washing chamber. When the fabric moves, it passes through the working range of the spray system, thereby undergoing spray cleaning. A transfer roller is rotatably connected to the upper end of the unloading bracket. After washing, the fabric is wrapped around the transfer roller to complete the unloading and stacking process, thus completing the continuous enzymatic treatment process.

[0054] The implementation principle of the continuous enzymatic treatment device for Tencel fabrics in this application embodiment is as follows: By extending the fabric movement path, the fabric is allowed to remain sufficiently within the pretreatment chamber 2 after being sprayed with the enzymatic reaction solution. This ensures complete reaction before the fabric undergoes mechanical beating, matching the enzymatic reaction time with the mechanical beating time, thus reducing damage to the fabric structure caused by prolonged beating. The fabric reacts within the pretreatment chamber 2 without tension, and the uniform stacking of the fabric ensures identical reaction conditions in all parts, contributing to improved reaction efficiency. The continuous processing of the fabric helps reduce downtime, energy consumption, and improve work efficiency. All modules cooperate and coordinate with each other, and can be controlled by a PLC control system to achieve automatic adjustment of process parameters and real-time monitoring of the entire process.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

The pretreatment box (2) is provided with a drive (26) for driving the swing arm (221) to swing back and forth. The two limiting rollers (222) are parallel to each other and are set at one end of the swing arm (221) where it can move freely. The fabric passes between the two limiting rollers (222) and is in a vertical state. When the swing arm (221) swings, it drives the fabric to continuously fold on the stacking conveyor belt (21) through the limiting rollers (222).

5. The continuous enzyme treatment device for Tencel fabric according to claim 4, characterized in that: The stacking assembly (22) also includes two fixed rollers (224) and two clamping rollers (225). The two fixed rollers (224) are parallel to each other and are fixedly connected to the pretreatment box (2). The fabric is folded between the two fixed rollers (224). The clamping rollers (225) correspond one-to-one with the fixed rollers (224), and the two clamping rollers (225) are located between the two fixed rollers (224). The pretreatment box (2) is provided with a power component (27) for driving the clamping rollers (225) to swing radially. When the clamping rollers (225) are close to the fixed rollers (224), they cooperate with the fixed rollers (224) to clamp the fabric. When the clamping rollers (225) are far away from the fixed rollers (224), they are completely removed from the area where the fabric is located.
