Description

Technical Field

[0001] The invention relates to the field of fabric processing, in particular to a polyester-spandex fabric washing and shaping device and process. Background Art

[0002] In the textile industry, polyester-spandex fabrics are widely used in sportswear, casual wear, and other fields due to their unique performance advantages. However, existing dyeing and finishing technologies for polyester-spandex fabrics still have significant shortcomings in improving dyeing reproducibility and color fastness. High temperatures, in particular, can damage the spandex component, causing the fabric to lose its original elasticity and strength. Furthermore, traditional finishing techniques often fail to simultaneously improve the fabric's feel and gloss, limiting the quality of the final product.

[0003] To improve the dyeing and finishing of polyester-spandex fabrics, several commonly used methods include low-temperature wet heat setting, microwave radiation setting, and chemical modification. Low-temperature wet heat setting reduces the impact on spandex fibers by lowering the temperature, but this method is inefficient and time-consuming. Microwave radiation setting effectively shortens the processing time, but its applicability for fabrics with complex patterns is limited. Chemical modification may introduce harmful substances, which is not environmentally friendly. While these three methods each have their own advantages, in practice, none fully meets the multiple requirements for high-quality polyester-spandex fabric production. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1 The present invention provides a polyester-spandex fabric washing and shaping device, comprising a washing structure and a cooling structure. The washing structure comprises a washing tank 1, wherein the washing tank 1 is loaded with washing liquid. Both sides of the washing tank 1 are provided with a transmission component and a tension adjustment component. When the polyester-spandex fabric washing and shaping device is in use, the transmission component can be used to drive the polyester-spandex fabric to be processed to move in the washing tank 1. The tension adjustment component automatically adjusts the tension of the polyester-spandex fabric to ensure that the fabric is flat and not twisted. As the fabric passes through the washing tank 1, the residual dye and attachments on the fabric are fully cleaned, and at the same time, the fabric is appropriately stretched to enhance the interweaving force between fibers, thereby improving color fastness and wrinkle resistance.

[0021] The transmission assembly includes a support roller 8, two conveying rollers 6 rotatably connected to the support roller 8, and a servo motor 34 that drives the conveying rollers 6 to rotate. The two conveying rollers 6 are vertically distributed. The support roller 8 is connected to the washing tank 1. When the servo motor 34 is working, it can drive the conveying rollers 6 connected thereto to rotate. The coordinated use of the two conveying rollers 6 in the transmission assembly can realize the conveying of fabrics.

[0022] The tension adjustment assembly includes a hydraulic telescopic rod 12, a support rod connected to the end of the output shaft of the hydraulic telescopic rod 12, and two adjusting rollers 5 movably connected to the support rod. The two adjusting rollers 5 are in a vertically distributed state. The hydraulic telescopic rod 12 can be connected to the support roller 8. The extension and retraction of the hydraulic telescopic rod 12 can change the position of the support rod connected thereto. The support rod drives the two adjusting rollers 5 connected thereto to move. When the height of the adjusting roller 5 changes, the tension of the fabric can change.

[0023] A heating component and a temperature sensor 32 are provided in the washing tank 1. The heat generated by the heating component when it is working can heat the washing liquid in the washing tank 1. The temperature sensor 32 is used to detect the temperature of the washing liquid in real time, so that the control system in the polyester-spandex fabric washing and setting device can accurately control the temperature of the washing liquid. When the polyester-spandex fabric washing and setting device is in use, the staff can determine the appropriate washing temperature according to the color depth and thickness of the polyester-spandex fabric to be processed.

[0024] The heating component can be an electric heating rod 9, which is evenly distributed at the bottom of the water washing tank 1. In order to speed up the uniform distribution of heat of the heating component, a circulation component is provided on the water washing tank 1, and the circulation component includes a circulation pump 4 and a flow equalizing plate 33. The circulation pump 4 is arranged outside the water washing tank 1, and the liquid inlet end of the circulation pump 4 is connected to the inner cavity of the water washing tank 1 through the liquid inlet pipe 19, and the liquid outlet end of the circulation pump 4 is connected to the inner cavity of the flow equalizing plate 33 through the liquid outlet pipe 37. One end of the liquid outlet pipe 37 is connected to the liquid outlet end of the circulation pump 4, and the other end of the liquid outlet pipe 37 extends to the inner cavity of the flow equalizing plate 33. The inner side of the inner cavity of the flow equalizing plate 33 is evenly provided with drainage holes 38. When the circulation pump 4 is working, it can pump the washing liquid in the water washing tank 1 into the inner cavity of the flow equalizing plate 33, and the washing liquid in the inner cavity of the flow equalizing plate 33 is evenly sprayed into the inner cavity of the water washing tank 1 through the drainage holes 38.

[0025] The inner cavity of the washing tank 1 is provided with a guide roller 35, which can guide the fabric so that the fabric moves along a specific route in the washing tank 1. Under the action of the guide roller 35, the fabric at the inlet of the washing tank 1 and the fabric at the outlet of the washing tank 1 are both in a vertical state. Figures 1 to 4 shown.

[0026] During the dyeing process, some industrial pulp, cotton wool, floating hair and floating color may remain on the fabric. During the cleaning process, these attachments will float on the liquid surface. Some impurities will adhere to the fabric when the fabric is out of water, affecting the fabric cleaning effect. In order to avoid the impurities floating on the liquid surface affecting the fabric cleaning efficiency, a dust removal component is provided on the washing tank 1, such as Figures 1 to 7 As shown, the dust removal assembly includes a dust blowing plate 13 arranged above the water washing tank 1, an opening and closing plate 17 and a blower 3 arranged on the other side of the water washing tank 1.

[0027] The air outlet of the blower 3 is connected to the inner cavity of the dust blowing plate 13 through the air outlet pipe 39. When the blower 3 is working, the outside air can be blown into the inner cavity of the dust blowing plate 13 through the air outlet pipe 39. The bottom of the dust blowing plate 13 is evenly provided with air blowing pipes 40. The two adjacent air blowing pipes 40 are in a staggered state, and the dust blowing plate 13 is provided with at least three, such as Figures 1 to 4 As shown, the air in the inner cavity of the dust-blowing plate 13 is ejected through the blowing pipe 40. The airflow ejected from the blowing pipe 40 can blow away impurities floating on the liquid surface, causing the impurities to be gathered together and facilitated. The outlet pipe 39 can be made of a corrugated tube. The outlet end of the blower 3 can be provided with a four-way pipe, one end of which is connected to the outlet end of the blower 3, and the other three ends of the four-way pipe are respectively connected to the outlet pipe 39, and the other end of the outlet pipe 39 is connected to the dust-blowing plate 13.

[0028] The dust blowing plate 13 is connected to the water washing tank 1 through a transmission structure. The transmission structure includes a ball screw 16 movably connected to the top of the water washing tank 1. The outer ring of the ball screw 16 is threadedly connected to a ball nut. The ball nut is connected to the dust blowing plate 13. Two adjacent ball screws 16 are connected by a synchronous belt 31. A servo motor 30 is provided on one side of the top of the water washing tank 1. The end of the output shaft of the servo motor 30 is connected to the ball screw 16 through a reducer. Through the setting of the transmission structure, the rotation of the servo motor 30 can drive the ball screw 16 connected to it to rotate, and the rotating ball screw 16 can drive other ball screws 16 to rotate through the synchronous belt 31. The rotation of the ball screw 16 causes the ball nut threadedly connected to it to move in the direction of the ball screw 16. When the ball nut moves, it drives the dust blowing plate 13 fixedly connected to it to move. The dust blowing plate 13 can drive the blowing pipe 40 to move. The airflow ejected from the blowing pipe 40 can blow away impurities floating on the liquid surface, so that the impurities are separated from the fabric, and the amount of impurities adhering to the fabric when the fabric is out of water is reduced.

[0029] An impurity filter box 11 is provided on the other side of the water washing tank 1 away from the flow equalizing plate 33. The liquid inlet end of the impurity filter box 11 is inclined, and the opening and closing plate 17 is located at the high end of the liquid inlet end of the impurity filter box 11. The liquid inlet end of the impurity filter box 11 is movably connected with a rotating shaft 26, and the rotating shaft 26 is fixedly connected to the opening and closing plate 17. A servo motor 25 is provided on one side of the water washing tank 1, and the rotating shaft 26 is driven by the servo motor 25. When the servo motor 25 drives the rotating shaft 26 to rotate, the rotating shaft 26 drives the opening and closing plate 17 to rotate. When the opening and closing plate 17 is in the open state, the inner cavity of the impurity filter box 11 is connected to the inner cavity of the water washing tank 1. At this time, impurities floating on the liquid surface can enter the inner cavity of the impurity filter box 11. When the opening and closing plate 17 is in the closed state, the normal operation of the polyester-spandex fabric washing and shaping device is facilitated. The inner cavity of the impurity filter box 11 and the inner cavity of the water washing tank 1 are separated by the opening and closing plate 17.

[0030] The bottom end of the inner cavity of the impurity filter box 11 is fixedly connected with an inclined filter plate 28, and the bottom of the inner cavity of the impurity filter box 11 is fixedly connected with a second liquid inlet pipe 29. The second liquid inlet pipe 29 is located below the high end of the inclined filter plate 28. One end of the second liquid inlet pipe 29 is provided with an electric ball valve. The liquid outlet end of the impurity filter box 11 is connected to the liquid inlet end of the circulation pump 4 through the second liquid inlet pipe 29. Through the setting of the inclined filter plate 28, the inclined filter plate 28 can filter the washing liquid entering the impurity filter box 11, intercept impurities, and facilitate the recycling of the washing liquid.

[0031] The dust removal assembly also includes two first spray plates 7 connected to the liquid outlet end of the circulation pump 4 through the liquid outlet pipe 2 41. When the circulation pump 4 is working, the washing liquid is pumped into the inner cavity of the first spray plate 7. The washing liquid in the first spray plate 7 is sprayed onto the fabric through the spray holes arranged on the inner side thereof, flushing the fabric and further improving the fabric cleaning effect.

[0032] The cooling structure is set at the outlet of the washing structure. The fabric after washing is cooled by the cooling structure, which quickly reduces the temperature of the fabric, protects the spandex from high temperature damage, and maintains good elasticity and strength.

[0033] The cooling structure includes a cooling box 14, a guide roller group 18 arranged at the bottom end of the inner cavity of the cooling box 14, two second spray plates 10 arranged at the top end of the inner cavity of the cooling box 14, another transmission component and a cooling water circulation device 2 arranged above the second spray plate 10, the fluid discharge end of the cooling water circulation device 2 is connected to the inner cavity of the second spray plate 10 through a cooling water pipe 42, a drain pipe 43 is provided on one side of the bottom end of the cooling box 14, the other end of the drain pipe 43 is connected to the return end of the cooling water circulation device 2, and the bottom of the inner cavity of the cooling box 14 is inclined, and the drain pipe 43 is located at the lower end of the bottom of the inner cavity of the cooling box 14. When the cooling water circulation device 2 is working, it can pump cooling water into the inner cavity of the second spray plate 10, and the second spray plate 10 sprays the fabric located inside it to cool it down, and the fabrics inside the two second spray plates 10 are in a vertical state. The cooling water circulation device 2 is a prior art. In some embodiments of the present application, the cooling water circulation device 2 is disclosed in the authorized patent document with application number CN202322508895.7.

[0034] Another transmission assembly is located above the guide roller group 18, as shown in FIG. Figure 3 and Figure 4 As shown, with such an arrangement, the cooling water sprayed from the second spray plate 10 can fall on the fabric wrapped around the guide roller set 18, thereby achieving pre-cooling of the fabric and improving the fabric cooling efficiency.

[0035] Example 2 The difference between Example 2 and Example 1 is that a partition component is provided in the middle of the inner cavity of the water washing tank 1, and the partition component divides the inner cavity of the water washing tank 1 into two cleaning chambers. Each cleaning chamber is provided with a guide roller 35, a heating component, a temperature sensor 32, a flow equalizing plate 33 and an opening and closing plate 17. Through the setting of the partition component, the partition component can be used to intercept impurities, and the fabric can be washed multiple times, thereby improving the fabric cleaning effect.

[0036] like Figure 8 As shown, the partition assembly includes a fixed plate 15 and a lifting roller 23. A groove is provided at the bottom of the fixed plate 15, and a roller 24 is movably connected to the top of the groove. The lifting roller 23 is arranged below the roller 24, and the lifting roller 23 is connected to the bottom of the inner cavity of the washing tank 1 through a telescopic belt 21 and an electric telescopic rod 22. The electric telescopic rod 22 is fixedly connected to the bottom of the inner cavity of the washing tank 1, and the output shaft end of the electric telescopic rod 22 is fixedly connected to the middle part of the bottom of the lifting roller 23. Both sides of the bottom of the lifting roller 23 are fixedly connected with a telescopic belt 21, and the other end of the telescopic belt 21 is fixedly connected to the bottom of the inner cavity of the washing tank 1. The electric telescopic rod 22 can drive the lifting roller 23 to move, change the distance between the lifting roller 23 and the roller 24, so that the partition assembly can adapt to fabrics of various thicknesses, and the telescopic belt 21 is used to seal the gap between the lifting roller 23 and the bottom of the inner cavity of the washing tank 1. The material of the telescopic belt 21 can be high-temperature resistant rubber. And when the polyester-spandex fabric washing and shaping device needs to adapt to fabrics of different widths, a compensation block 20 can be fixed on the top of the lifting roller 23 to seal the excess gap between the lifting roller 23 and the roller 24 using the compensation block 20.

[0037] Example 3 Both the first and second spray plates 7 and 10 are equipped with nozzles with adjustable angles. The two adjustment rollers 5, conveyor roller 6, roller 24, lift roller 23, and guide roller 1 35 in the tension adjustment mechanism are all made of corrosion-resistant stainless steel with a smooth surface to prevent scratches on the fabric. The liquid inlet of the circulation pump 4 is connected to the liquid inlet pipe 19 and the two liquid inlet pipes 29 via a four-way pipe. The liquid outlet of the circulation pump 4 is connected to the two liquid outlet pipes 1 37 and the two liquid outlet pipes 2 41 via a five-way pipe. The fluid outlet of the cooling water circulation device 2 is connected to the two cooling water pipes 42 via a three-way pipe.

[0038] From the above description, it can be seen that when the polyester-spandex fabric washing and shaping device is in use, residual dyes, lint and other attachments on the fabric are removed by water washing, and at the same time, the fabric is appropriately stretched to enhance the interweaving force between fibers, thereby improving color fastness and wrinkle resistance; after leaving the washing tank 1, the cooling system is immediately started, and cold water spray is used to quickly reduce the temperature of the fabric, thereby protecting the spandex from high temperature damage and maintaining good elasticity and strength.

[0039] The polyester spandex fabric washing and shaping device further comprises a guide belt 36, the thickness of the guide belt 36 is the same as the thickness of the polyester spandex fabric to be processed, the width of the guide belt 36 is the same as the width of the polyester spandex fabric to be processed, and the state of the guide belt 36 on the polyester spandex fabric washing and shaping device is as follows: Figures 1 to 4 As shown, when the polyester-spandex fabric washing and shaping device is in use, the guide belt 36 is used to guide the fabric so that the fabric can pass through each roller group in sequence, which is convenient for cleaning the fabric.

[0040] The polyester-spandex fabric washing and shaping device also includes a control system, which can be a PLC control system. The control system controls the operation of the washing structure and the cooling structure. The entire process is carried out in an orderly manner under the unified scheduling of the control system to ensure that each step is executed accurately.

[0041] The electrical components involved in this application are all existing technologies. Technical personnel in this field are familiar with their connection methods. Through these personnel, all electrical components in this application are connected to their corresponding power supplies through wires, and a suitable control system is selected according to actual conditions to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed between the electrical components in a sequential working order. The detailed connection means are well known in this field. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0042] A polyester-spandex fabric washing and shaping device for washing and shaping polyester-spandex fabric comprises the following steps: Step 1: The staff determines the appropriate washing temperature and treatment time according to the color depth and thickness of the polyester spandex fabric to be processed; put the washing liquid for cleaning the polyester spandex fabric into the washing tank 1, and fix the end of the guide belt 36 located at the inlet end of the washing tank 1 to the polyester spandex fabric to be processed. The fabric and the guide belt 36 can be connected with glue. The type of glue can be selected according to needs and is not limited here; Step 2: Start the heating component and use it to heat the washing liquid in the washing tank 1. During the heating process, the circulating pump 4 works to pump the liquid in the washing tank 1 into the inner cavity of the flow equalizer 33. The washing liquid in the inner cavity of the flow equalizer 33 is discharged through the drainage hole 38, thereby improving the heat uniformity of the heating component. During this process, the temperature of the washing liquid is detected in real time by the temperature sensor 32 until the temperature of the washing liquid meets the requirements. Step 3: The transmission component works, and the transmission component drives the guide belt 36 to move, and the guide belt 36 drives the fabric to move, and the fabric can enter the washing tank 1. As the fabric passes through the washing tank 1, the residual dye on it is fully washed away. At the same time, under the action of the tension adjustment component, the fabric is properly stretched, and the interweaving force between the fibers is enhanced, thereby improving color fastness and wrinkle resistance. In the washing process, the dust removal component works to blow away floating objects on the liquid surface to prevent impurities from affecting the fabric cleaning effect. Step 4: The circulation pump 4 pumps the washing liquid into the inner cavity of the first spray plate 7. After the fabric leaves the washing liquid, the first spray plate 7 sprays the washing liquid onto the fabric to rinse the fabric. The rinsed fabric enters the cooling box 14. Step 5. When the fabric moves to the inner side of the second spray plate 10, the cooling water sprayed from the second spray plate 10 is sprayed onto the fabric to cool the fabric, protect the spandex from being damaged by high temperature, and maintain good elasticity and strength. The sprayed water falls onto the fabric wrapped around the guide roller group 18 under the action of gravity, thereby pre-cooling the fabric and increasing the fabric cooling speed. The cooled fabric is transported away by another transmission component. When the guide belt 36 is separated from the polyester-spandex fabric washing and shaping device, the staff separates the guide belt 36 from the fabric and fixes the guide belt 36 at the end of the fabric. The fabric is used to drive the guide belt 36 to reset, which is convenient for the reuse of the polyester-spandex fabric washing and shaping device.
