Description

Technical Field

[0001] This invention relates to the field of dyeing and finishing equipment technology, and in particular to a narrow-width enzyme washing machine and its control system and method. Background Technology

[0002] Enzymatic washing of fabrics is a water-washing process that uses biological enzymes to treat the surface of fabrics. Its core function is to achieve effects such as softness, anti-aging, pilling removal, and color enhancement by controlling and selectively degrading cellulose through enzymes.

[0003] Current enzyme washing methods require cutting the fabric into small rolls before placing them in a special washing vat. While this achieves the desired effect, it has the following drawbacks: 1. The entire processing procedure is complicated. For example, it requires multiple workers (about 6 people) to work together to turn and open the textile fabric to be processed. After that, the prepared textile fabric needs to be put into the washing vat manually. After the washing vat is completed, it requires multiple people (6-7 people) to work together to complete the work of taking the fabric out of the vat and sorting it. Second, the process generates a large amount of wastewater, which not only pollutes the environment but also wastes raw materials (washing a vat involves making a vat of cloth and filling it with water). Third, the automation level of the entire processing is low, the labor consumption is high and the labor intensity of workers is high, which increases the production cost of finished products. Fourth, because textile fabrics need to be cut into small pieces, there is a serious waste of textile fabrics and labor, and the products are prone to producing a large number of unwanted wrinkles, dead wrinkles, and sand marks, resulting in defective products and reducing the yield of finished products.

[0004] Therefore, this case is brought. Summary of the Invention

[0005] The purpose of this invention is to provide a narrow-width enzyme washing machine and its control system and method. The entire enzyme washing process does not require manual intervention and achieves enzyme washing of the fabric by combining fabric humidification and airflow gentle beating. At the same time, it can improve the softness and fluffiness of the fabric after enzyme washing and reduce processing costs.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A narrow-width enzyme washing machine, comprising: A plurality of fabric circulation units, each fabric circulation unit including a conveying pipe, a beater plate located at both ends of the conveying pipe, and a fabric storage hopper located below the beater plate. The two ends of the conveying pipe are respectively used for guiding and discharging fabric. The wall of the fabric storage hopper is provided with a water filter hole. A flow guiding mechanism is provided in the middle of the conveying pipe. The flow guiding mechanism is used to introduce airflow and selectively guide the airflow from the middle of the conveying pipe to one end or the other end, so as to drive the fabric in the conveying pipe to hit the beater plates on both sides. A fabric guiding mechanism is provided at both ends of the fabric flow unit and is used to guide the fabric into or out of the fabric flow unit. A liquid storage tank is used to store fabric treatment liquid. The liquid storage tank is located below the fabric storage hopper and is provided with a liquid inlet. The liquid inlet is used to receive the fabric treatment liquid filtered from the water filter hole. A spray piping system includes a pump body and a nozzle. The input end of the pump body is connected to the output end of the liquid storage tank, and the output end of the pump body is connected to the nozzle. The nozzle is installed in the fabric guiding mechanism and / or in the delivery pipe and / or at the openings at both ends of the delivery pipe for spraying fabric treatment liquid onto the fabric. A fan, the output end of which is connected to the input end of the flow guiding mechanism, is used to form an airflow to be delivered to the flow guiding mechanism.

[0007] Furthermore, the conveying pipe is horizontally arranged and includes a middle section pipe and side sections pipes located on both sides of the axial direction of the middle section pipe. The middle section pipe includes a middle outer pipe and a middle inner pipe. The middle outer pipe is a T-shaped tee pipe, including a horizontal connection port one, a connection port two, and a vertical connection port three. The connection port one and the connection port two are respectively connected to the side sections pipes on both sides. The middle inner pipe is a straight pipe horizontally arranged between the connection port one and the connection port two, and the outer diameter of the middle inner pipe is smaller than the inner diameter of the pipe between the connection port one and the connection port two. The flow guiding mechanism includes a rotating shaft drive unit, a rotating shaft, flow guiding blades, and a flow guiding pipe. The upper end of the flow guiding pipe is connected to the connection port 3, and the lower end is connected to the output end of the fan. The flow guiding blades are installed inside the T-shaped tee pipe via the rotating shaft and are located directly below the middle section inner pipe. The middle section inner pipe has an isolation plate in the middle of its outer wall. The isolation plate extends upward to the inner wall of the middle section outer pipe and downward to the rotating shaft. The rotating shaft drive unit is used to drive the rotating shaft to make the flow guiding blades reciprocate to rotate, so as to guide the airflow into the delivery pipe and flow from the middle of the delivery pipe to one end or the other end.

[0008] Furthermore, the rotating shaft drive unit includes a cylinder and a linkage lever, wherein the cylinder seat end of the cylinder is rotatably connected to the external frame, the piston end of the cylinder is rotatably connected to one end of the linkage lever, and the other end of the linkage lever is rotatably connected to the rotating shaft.

[0009] Furthermore, a filter module is provided on the pipeline of the spray pipeline system.

[0010] Furthermore, the system includes a fabric treatment liquid replenishment unit, comprising a liquid storage tank and a second pump body. The input end of the second pump body extends into the liquid storage tank via a pipeline, and the output end of the second pump body extends into the liquid storage tank via a pipeline.

[0011] Furthermore, it includes a return air duct, the air inlet of which is located above both ends of the delivery pipe, and the air outlet of the return air duct is connected to the input end of the fan through a filter module.

[0012] Furthermore, the fabric circulation unit includes an enzyme-washing fabric circulation unit, an inactivation fabric circulation unit, and a water-washing fabric circulation unit. The fabric is output after passing through the enzyme-washing fabric circulation unit, the inactivation fabric circulation unit, and the water-washing fabric circulation unit in sequence. A heating module is provided inside the liquid storage tank and / or in the delivery pipe and / or at the air inlet of the fan.

[0013] Furthermore, the surface of the striking plate is covered with a flexible layer.

[0014] A control system for the narrow-width enzyme washing machine includes: The database module is used to store fabric parameters and processing solution parameters; The weighing module is installed at the fabric storage hopper and is used to measure the weight of the fabric in the two fabric storage hoppers on both sides. The temperature measurement module is used to measure the temperature of the liquid storage tank and the delivery pipe; The treatment fluid monitoring module is used to monitor the pH value, concentration, and liquid level of the treatment fluid in the storage tank; Pump body driver, used to control the start and stop of the pump body; Fan drive, used to control the speed of the fan; The central control module is used to coordinate the operation of the pump, fan, heating module and shaft drive unit based on fabric parameters, treatment fluid parameters, feedback weight signals, temperature signals and treatment fluid monitoring signals.

[0015] Furthermore, it includes an alarm module, which includes a pressure sensor and an audible and visual alarm installed inside the delivery pipe. The pressure sensor is used to monitor the airflow pressure inside the delivery pipe. The central control module issues an alarm message when the feedback weight signal, temperature signal, processing fluid monitoring signal, or airflow pressure signal is abnormal, according to a preset threshold range.

[0016] A control method for the narrow-width enzyme washing machine includes tapping control and enzyme washing control; The tapping control includes the following process: When 0≤T<10min, the beating force is set between 0.5-1N and the beating frequency is set between 10-15 times / minute, where T represents the time for the fabric to be enzyme washed. When 10≤T<30min, the patting force should be set between 1-2N and the patting frequency should be set between 20-30 times / minute. When T≥30min, the patting force should be set between 0.5-1N and the patting frequency should be set between 10-15 times / minute; The enzyme washing control includes the following processes: The fabric is first transported in the enzyme washing fabric flow unit. Temperature control is required to maintain the optimal activity of the enzyme, generally between 40-60℃. The fabric is then transported in the inactivation fabric circulation unit, and the temperature must be controlled just enough to completely destroy the enzyme activity, generally between 80-85℃. Finally, the fabric is conveyed in the washing fabric circulation unit, with the temperature controlled between 30℃ and 40℃.

[0017] The advantages of this invention are: 1. This solution abandons the traditional enzyme washing and soaking process, and innovatively adopts a non-contact treatment method of "guide roller conveying + gentle beating + enzyme washing". By setting a T-shaped three-way guide mechanism in the middle of the horizontal conveying pipe, combined with reciprocating rotating guide blades, the airflow direction can be precisely switched, allowing the fabric to impact both ends in the conveying pipe for gentle beating. The gentle beating makes the fabric more fluffy and soft. At the same time, enzyme solution is sprayed onto the fabric during the conveying and beating process. The gentle beating can promote the penetration of enzyme solution and micro-abrasion of the fabric fiber surface to achieve uniform aging and lint removal effects. On the other hand, it can avoid fabric damage, holes or wrinkles caused by hard friction, significantly improving the yield and hand feel quality of the finished product. In addition, the equipment uses guide rollers to realize the fully automated conveying of fabric during the enzyme washing process, eliminating complicated processes such as fabric cutting, loading and unloading, and handling, significantly improving the level of automation and fabric utilization.

[0018] 2. During the enzyme washing process, temperature is a key variable affecting enzyme activity and reaction rate. This solution implements a three-stage intelligent temperature control strategy for the entire enzyme washing process: maintaining 40–60℃ in the enzyme washing unit stage to activate the cellulase for optimal catalytic efficiency; rapidly raising the temperature to 80–85℃ after entering the inactivation unit stage to ensure complete inactivation of the enzyme protein and prevent color difference or strength reduction caused by continuous enzyme action in subsequent water washing; and finally, cooling to 30–40℃ for gentle rinsing in the water washing unit stage to quickly remove residual enzyme solution and protect the fiber structure. Each heating module is independently configured in the storage tank, delivery pipe, or air duct, and with real-time temperature monitoring feedback, ±1℃ precision control is achieved to ensure the stability and reproducibility of the enzyme reaction.

[0019] 3. During the enzyme washing process, the intensity of airflow beating is effectively controlled according to the washing time. Low-intensity beating is used in the initial stage to avoid fiber damage caused by high-intensity beating before the enzyme solution has fully penetrated. In the middle stage (10–30 minutes), the beating intensity is increased (1–2 N) to accelerate enzyme-fiber contact, fiber swelling, and dye stripping. In the later stage, low-intensity beating is resumed, combined with inactivation and rinsing, to avoid excessive friction and prevent secondary damage to the treated fabric. This variable linkage control of "temperature + intensity" achieves an optimal balance between the chemical action of the enzymes and the mechanical action of the physical beating.

[0021] The present invention will be further described in detail below with reference to embodiments. It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer" used in this document indicate the orientation or positional relationship based on the attached embodiments. Figure 3 The orientations or positional relationships shown are for the purpose of facilitating the description of the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0022] like Figures 1 to 11 As shown in the figure, this embodiment proposes a narrow-width enzyme washing machine, including a fabric flow unit 1, a fabric guiding mechanism 2, a liquid storage tank 3, a spray pipeline system 4, and a fan 5.

[0023] refer to Figure 2 or Figure 3 The device includes five fabric flow units 1 arranged in a Y-direction. Specifically, the five fabric flow units 1, in the Y-direction, include, in sequence, an enzyme-washing fabric flow unit a101, an enzyme-washing fabric flow unit b102, an enzyme-washing fabric flow unit c103, an inactivation fabric flow unit d104, and a water-washing fabric flow unit e105. (Reference) Figure 10 When in use, the fabric passes through the enzyme washing fabric circulation unit a101, enzyme washing fabric circulation unit b102, enzyme washing fabric circulation unit c103, inactivation fabric circulation unit d104 and water washing fabric circulation unit e105 in sequence before being output.

[0024] refer to Figures 5 to 9Each fabric circulation unit 1 includes a conveying pipe 106, striking plates 108 located at both ends of the conveying pipe 106, and a fabric storage hopper 109 located below the striking plates 108. The two ends of the conveying pipe 106 are open for fabric inlet and outlet, respectively, and the wall of the fabric storage hopper 109 is provided with filter holes. A flow guiding mechanism 107 is provided in the middle of the conveying pipe 106. The flow guiding mechanism 107 is used to introduce airflow and selectively guide the airflow from the middle of the conveying pipe 106 to one end or the other end, so as to drive the fabric in the conveying pipe 106 to impact the striking plates 108 on both sides.

[0025] Specifically, such as Figure 6 and Figure 8 As shown, the conveying pipe 106 is horizontally arranged and includes a middle section pipe and side sections pipes 1061 located on both sides of the axial direction of the middle section pipe. The middle section pipe includes a middle outer pipe 1062 and a middle inner pipe 1063. The middle outer pipe 1062 is a T-shaped tee pipe, including a horizontal connection port 10621, a horizontal connection port 10622, and a vertical connection port 3 10623. The connection port 10621 and the connection port 2 10622 are respectively connected to the side sections pipes 1061 on both sides. The middle inner pipe 1063 is a straight pipe horizontally arranged between the connection port 10621 and the connection port 2 10622, and the outer diameter of the middle inner pipe 1063 is smaller than the inner diameter of the pipe between the connection port 10621 and the connection port 2 10622.

[0026] like Figure 7 and Figure 8 As shown, the flow guiding mechanism 107 includes a shaft drive unit 1071, a shaft 1072, a flow guide vane 1073, and a flow guide pipe 1074. The upper end of the flow guide pipe 1074 is connected to the connection port 10623, and the lower end is connected to the output end of the fan 5. The flow guide vane 1073 is installed inside the T-shaped tee pipe via the shaft 1072 and is located directly below the middle section inner pipe 1063. A partition plate 1075 is provided in the middle of the outer wall of the middle section inner pipe 1063. The partition plate 1075 extends upward to the inner wall of the middle section outer pipe 1062 and downward to the shaft 1072. The partition plate 1075 divides the T-shaped tee pipe space into two independent airflow guiding chambers. The shaft drive unit 1071 drives the shaft 1072 to make the flow guide vane 1073 reciprocate, so as to guide the airflow into the delivery pipe 106 and flow from the middle of the delivery pipe 106 to one end or the other. Figure 9 As shown, when the guide vane rotates to the left, the introduced airflow is drawn into the right-side side section pipe 1061 and ejected from the right end of the delivery pipe 106; similarly, when the guide vane rotates to the right, the introduced airflow is drawn into the left-side side section pipe 1061 and ejected from the left end of the delivery pipe 106. The striking principle mentioned in this application is as follows: refer to Figure 5The fabric entering the right-side storage hopper 109 enters the conveying pipe 106, then flows into the left-side storage hopper 109 and is output. A certain amount of fabric is required in both storage hoppers 109. When the airflow flows to the left in the conveying pipe 106, it causes the fabric to impact the left-side striking plate 108 and fall into the left-side storage hopper 109; when the airflow flows to the right in the conveying pipe 106, it causes the fabric to impact the right-side striking plate 108 and fall into the right-side storage hopper 109. Thus, by switching the airflow direction left and right, the fabric is flexibly impacted and patted on the striking plates 108 on both sides, making the fabric more fluffy and soft. Preferably, this embodiment provides a flexible layer on the striking plate 108, such as a silicone buffer layer (2-3mm thick, Shore A 50-60 hardness), to reduce the impact force during fabric impact and prevent snagging. Preferably, such as... Figure 6 As shown, in this embodiment, a guide plate 110 is provided between the fabric storage hopper 109 and the port of the conveying pipe 106. The guide plate 110 is located diagonally below the beating plate 108. This design allows the fabric impacting the beating plate 108 to slide down into the fabric storage hopper 109 through the guide plate 110. Furthermore, it allows some of the impact airflow to flow back to the fabric surface, creating a secondary beating effect and improving beating efficiency and uniformity. The switching of the airflow direction is achieved based on the weighing sensors installed at both fabric storage hoppers 109. When the weight of the left fabric storage hopper 109 is greater than a certain threshold of the right fabric storage hopper 109, the airflow direction is switched to the right; when the weight of the right fabric storage hopper 109 is greater than a certain threshold of the left fabric storage hopper 109, the airflow direction is switched to the left.

[0027] refer to Figure 7 The rotating shaft drive unit 1071 includes a cylinder 10711 and a linkage rocker arm 10712. The cylinder seat end of the cylinder 10711 is rotatably connected to the external frame, the piston end of the cylinder 10711 is rotatably connected to one end of the linkage rocker arm 10712, and the other end of the linkage rocker arm 10712 is rotatably connected to the rotating shaft 1072.

[0028] like Figure 1 As shown, the fabric guiding mechanism 2 is located at both ends of the fabric flow unit 1, and is used to guide or guide the fabric into or out of the fabric flow unit 1. (Reference) Figure 4 and Figure 10In this embodiment, the fabric guiding mechanism 2 includes 7 guide rollers (guide rollers a201 to g207) and 14 guide holes (guide holes a208 to n221). The fabric conveying path is as follows: entering guide hole a208 → passing through guide roller a201 → guide hole b209 → storage hopper 109 on the right side of enzyme washing fabric circulation unit a101 → conveying pipe 106 of enzyme washing fabric circulation unit a101 → storage hopper 109 on the left side of enzyme washing fabric circulation unit a101 → guide hole c210 → guide roller b202 → guide hole d211 → storage hopper 109 on the left side of enzyme washing fabric circulation unit b102 → conveying pipe 106 of enzyme washing fabric circulation unit b102 → storage hopper 109 on the right side of enzyme washing fabric circulation unit b102 → guide hole e212 → guide roller c203 → guide hole f213 → Storage hopper 109 on the right side of enzyme-washing fabric flow unit c103 → Delivery pipe 106 of enzyme-washing fabric flow unit c103 → Storage hopper 109 on the left side of enzyme-washing fabric flow unit c103 → Guide hole g214 → Guide wheel d204 → Guide hole h215 → Storage hopper 109 on the left side of inactivation fabric flow unit d104 → Delivery pipe 106 of inactivation fabric flow unit d104 → Storage hopper 109 on the right side of inactivation fabric flow unit d104 → Guide hole i216 → Guide wheel e205 → Guide hole j217 → Guide hole k218 → Guide wheel f206 → Guide hole l219 → Storage hopper 109 on the right side of washing fabric flow unit e105 → Delivery pipe 106 of washing fabric flow unit e105 → Storage hopper 109 on the left side of washing fabric flow unit e105 → Guide hole m220 →Guide roller g207 →Guide hole n221, complete enzyme washing and discharge the fabric.

[0029] refer to Figure 1 and Figure 6The storage tank 3 is used to store the fabric treatment solution, which includes liquids such as enzymes, auxiliary agents, and water. For example, the storage tanks 3 on both sides of the enzyme washing fabric circulation units a, b, and c store a mixture of enzyme solution and auxiliary agents; the storage tanks 3 on both sides of the inactivation fabric circulation unit d store high-temperature water (80-85℃); and the storage tanks 3 on both sides of the water washing fabric circulation unit e store room-temperature water (30-40℃). The storage tank 3 is located below the fabric storage hopper 109 and has a liquid inlet for receiving the fabric treatment solution filtered from the filter holes. In addition, this embodiment also includes a fabric treatment solution replenishment unit 6, which includes a storage tank 601 and a second pump body 602. The input end of the second pump body 602 extends into the storage tank 601 through a pipeline, and the output end of the second pump body 602 extends into the storage tank 3 through a pipeline. The storage tank 3 is equipped with a treatment liquid monitoring module to monitor the pH value, concentration and liquid level of the treatment liquid in the storage tank 3. When the pH value, concentration or liquid level needs to be adjusted, the pH value, concentration and liquid level of the treatment liquid in the storage tank 3 are adjusted by activating pump body 2 602 (there are multiple pump bodies 602, one pump corresponds to one storage tank 601).

[0030] The spray piping system 4 includes a pump body 401 and a nozzle. The input end of the pump body 401 is connected to the output end of the liquid storage tank 3, and the output end of the pump body 401 is connected to the nozzle. The nozzle can be installed in the fabric guiding mechanism 2 and / or in the delivery pipe 106 and / or at the openings at both ends of the delivery pipe 106, for spraying fabric treatment liquid onto the fabric. Preferably, in this embodiment, it is installed at 14 fabric guiding holes (fabric guiding holes a208 to n221), specifically as follows: Figure 6 As shown. Additionally, the spray piping system 4 is equipped with a filter module 403 to remove fiber debris from the piping (the beating process generates many impurities, such as fabric lint and dust). Preferably, the nozzles should be staggered to ensure the treatment liquid evenly covers both sides of the fabric. Part of the treatment liquid sprayed onto the fabric is carried away by the fabric, and part is filtered out through the filter holes on the fabric storage hopper and returned to the storage tank.

[0031] In this embodiment, the fan 5 is located below the fabric circulation unit 1. Preferably, each conveying pipe of the fabric circulation unit 1 is equipped with a fan 5, which facilitates the adjustment and control of the beating frequency and intensity within each conveying pipe. The entire unit also includes a return air duct. The air inlet of the return air duct 7 is located above both ends of the conveying pipe 106, and the air outlet of the return air duct 7 is connected to the input end of the fan 5 through a filter module 403. The output end of the fan 5 is connected to the lower end of the drain pipe 1074. This equipment requires heating of the enzyme solution and airflow during operation. The design of the return air duct enables waste heat recovery and utilization. Test data shows that it can reduce natural gas consumption by more than 80% and steam consumption by more than 75%, significantly reducing equipment operating costs.

[0032] As mentioned earlier, this equipment requires heating of the enzyme solution and airflow during operation. In this embodiment, a heating module is installed inside the storage tank 3 and at the air inlet of the fan 5. The heating module can adopt steam heating, heat exchanger heating, jacketed heating structure, etc. The specific heating parameter design is described below.

[0033] This embodiment proposes a control system for a narrow-width enzyme washing machine, such as... Figure 12 As shown, the system includes a database module, a weighing module, a temperature measurement module, a processing solution monitoring module, a pump driver, a fan driver, and a central control module. The database module stores fabric and processing solution parameters. During startup, by inputting these parameters, the central control module automatically selects the appropriate enzyme washing mode based on built-in strategies, such as automatically controlling the washing temperature, beating force, enzyme concentration, conveying rate, and beating frequency. The weighing module, located at the fabric storage hopper 109, measures the weight of the fabric in both hoppers 109. Based on the weight comparison between the two hoppers, the airflow direction in each fabric conveying unit is switched. The temperature measurement module measures the temperature at the storage tank 3 and the conveying pipe 106. The processing solution monitoring module monitors the pH value, concentration, and level of the processing solution in the storage tank 3. The pump driver controls the pump's start and stop. The fan driver controls the fan's speed. The central control module is used to coordinate the operation of the pump body, fan 5, heating module and shaft drive unit 1071 based on fabric parameters, processing liquid parameters, feedback weight signals, temperature signals and processing liquid monitoring signals.

[0034] The specific operation process of the device in this embodiment is as follows: 1. Before the fabric enters the equipment, the type of fabric is selected through the human-machine interface, and the specific parameters of the fabric (weight, thickness, etc.) and the type, concentration, pH value and initial temperature of the enzyme are determined (e.g., for denim, neutral cellulase 1.5%, pH 7.0, initial temperature 55℃ is used). For example, if type A enzyme is input into the fabric flow unit a101 for enzyme washing, then type A enzyme is also input into the fabric flow unit b102 for enzyme washing, while type B enzyme is input into the fabric flow unit c103 for enzyme washing. Type B enzyme is used to neutralize type A enzyme.

[0035] The selection of enzymes in existing washing tanks is also similar: first, soak with type A enzymes, then soak with type B enzymes, and finally rinse with water. However, this embodiment adds an inactivation process because even after type A and type B enzymes are neutralized, some enzyme solution will still remain on the fabric, and water may not be able to completely remove the enzyme solution. The residual enzyme solution will cause excessive enzymatic hydrolysis of the fabric, thereby damaging the fabric fibers. This embodiment completely deactivates the enzyme solution through the inactivation process, so even if the enzyme solution on the fabric is not completely rinsed off, it will not cause excessive enzymatic damage to the fabric.

[0036] 2. After the fabric enters the equipment, it travels and is conveyed in the equipment according to the direction described above. In this embodiment, the journey of the fabric in the equipment is divided into three stages: the initial stage of enzyme washing (first 10 minutes), the middle stage of enzyme washing (10-30 minutes), and the later stage of enzyme washing (after 30 minutes).

[0037] In the initial stage of enzyme washing, i.e., when 0 ≤ T < 10 min (T represents the time for enzyme washing of the fabric), the fabric is located in the fabric circulation unit a101 for enzyme washing. At this time, when the enzyme solution has not fully penetrated, low-intensity beating is used, with the beating force set between 0.5-1 N and the beating frequency set at 10-15 times / minute. This can avoid fiber damage caused by high-intensity beating when the enzyme solution has not fully penetrated (beating is essentially mechanical friction + impact force acting on the fiber surface. If strong beating is applied before the fiber is softened by the enzyme solution and a lubricating water film is formed, dry friction will occur between the fibers and between the fibers and the beating plate 108, which can easily lead to fiber breakage, pilling, or even holes). In addition, at this time, the temperature of the enzyme solution A needs to be controlled to maintain the optimal activity of the enzyme, which is generally between 40-60℃.

[0038] Reasonable gentle patting makes the fabric fluffier and softer. At the same time, enzyme solution is sprayed onto the fabric during the patting process. Gentle patting can promote the penetration of enzyme solution and micro-abrasion of fabric fiber surface to achieve uniform aging and depilation effect. On the other hand, it avoids fabric damage, holes or dead wrinkles caused by hard friction, significantly improving the yield of finished products and the hand feel quality.

[0039] During the mid-stage of enzyme washing, i.e., when 10 ≤ T < 30 min, the fabric flows in enzyme washing fabric flow units b102 and c103. The temperature control of enzyme solution A and enzyme solution B needs to maintain the optimal enzyme activity, generally between 40-60℃, such as 40-50℃ for acidic enzyme washing and 50-60℃ for neutral enzyme washing. The beating intensity is set to medium-high intensity, between 1-2N, and the beating frequency is set to 20-30 times / minute to accelerate fiber swelling and dye stripping.

[0040] In the later stages of enzyme washing, i.e., when T≥30min, the fabric is transported between the inactivation fabric flow unit d104 and the washing fabric flow unit e105. At this point, the enzyme washing is basically complete, and low-intensity patting needs to be resumed to avoid excessive friction and damage to the fabric. The patting force is set between 0.5-1N, and the patting frequency is set at 10-15 times / minute. Regarding temperature settings, in the inactivation fabric flow unit d104, the temperature control must be just enough to completely inactivate the enzyme (using hot water to rinse the fabric, deactivating or directly washing away the enzymes on the fabric), but the temperature should not be too high to avoid damaging the fabric; it is generally set at 80-85℃. After entering the washing fabric flow unit e105, a water spray wash is performed to remove residual enzyme solution and fiber debris, laying the foundation for subsequent softening finishing. The temperature is controlled between 30℃-40℃ to cool the fabric, ensuring a good rinsing effect, while avoiding the problem of residual enzyme solution being difficult to remove due to low temperatures.

[0041] The entire process requires no human intervention, achieving a collaborative operation of "precise temperature-controlled enzyme washing + gentle patting + uninterrupted conveying". Compared with existing processes, the treated fabric has 20-30% more softness and fluffiness, reduced fiber damage rate to below 5%, and significantly reduced energy consumption and chemical additive usage.

[0042] In this embodiment, the fan 5 is a vortex fan 5, and the power of the fan 5 is adjustable in the range of 0~5000W to achieve precise control of the airflow speed, drive the fabric to move back and forth in a tension-free state, and repeatedly impact the beater plate 108 to promote fiber swelling and enzyme penetration.

[0043] In addition, this device also includes an alarm module, which includes a pressure sensor and an audible and visual alarm installed in the delivery pipe. The pressure sensor is used to monitor the airflow pressure in the delivery pipe. The central control module issues an alarm message when the feedback weight signal, temperature signal, processing fluid monitoring signal, or airflow pressure signal (delivery pipe blockage) is abnormal according to a preset threshold range.

Any non-substantial modifications made to the present invention using this concept should fall within the protection scope of the present invention.
