Description

Technical Field

[0001] This application relates to the technical field of fabric dyeing, and in particular to an integrated dyeing apparatus and method for abrasion-resistant and wrinkle-resistant polyester fabric. Background Technology

[0002] Polyester's main component is polyester fiber, which is produced through a polycondensation reaction. This fiber possesses excellent abrasion and wrinkle resistance, resulting in highly durable fabrics. During production, polyester fabrics are dyed to produce different colors, meeting the aesthetic and fashion demands of clothing, home textiles, and other products.

[0003] In existing technology, based on the fabric material and desired color, appropriate amounts of dye and auxiliaries are accurately weighed, added to a certain amount of water, and stirred evenly to prepare a dye solution. The pre-treated fabric is then placed in the dye solution and dyed under specific temperature, time, and pH conditions, with continuous stirring during the dyeing process to ensure even coloring.

[0004] While such dyeing devices can ensure uniform dye diffusion in the dye bath and reduce the possibility of dye precipitation or excessively high local concentrations through continuous stirring during the dyeing process, in practical applications, the fabric tends to clump together during stirring, failing to fully unfold. This results in insufficient dyeing on the surfaces where the fabric pieces adhere, thus reducing the overall dyeing effect. Therefore, there is an urgent need for a dyeing device to further improve the uniformity of fabric dyeing. Summary of the Invention

[0005] To improve the uniformity of fabric dyeing, this application provides an integrated dyeing apparatus and method for abrasion-resistant and wrinkle-resistant polyester fabric.

[0006] Firstly, the integrated dyeing device for wear-resistant and wrinkle-resistant polyester fabric provided in this application adopts the following technical solution: An integrated dyeing device for wear-resistant and wrinkle-resistant polyester fabric includes a dyeing vat and a lifting frame mounted on the dyeing vat. The lifting frame is rotatably mounted on two take-up and untake-up rollers for winding the fabric. The lifting frame is equipped with a rotating component for driving the take-up and untake-up rollers to rotate. A dyeing zone is formed between the two take-up and untake-up rollers. Multiple reversing rollers for winding the fabric are rotatably mounted in the dyeing zone. The fabric is wound in a serpentine pattern in the dyeing zone. Each reversing roller has stirring blades on its outer peripheral wall.

[0007] By adopting the above technical solution, the fabric to be dyed is wound around one of the take-up and unwind rollers. After passing through multiple reversing rollers in the dyeing zone, the fabric is connected to another take-up and unwind roller. A lowering frame places the fabric inside the dyeing vat. A rotating component drives the take-up and unwind rollers to rotate, transferring the fabric from one roller to another. By switching the rotation direction of the take-up and unwind rollers, the fabric can be repeatedly switched between the two rollers. When the fabric passes through the dyeing zone, the multiple reversing rollers separate the fabric, reducing the possibility of uneven dyeing caused by the fabric surfaces sticking together. Furthermore, the rotation of the reversing rollers in the dyeing zone agitates the dye liquor through stirring blades, reducing the possibility of dye precipitation or excessively high local concentrations, thereby improving the dyeing effect of the fabric.

[0008] Optionally, the stirring blades of the reversing roller are arranged in two sets at intervals along the axial direction of the reversing roller, and a winding area for the fabric to be wound is formed between the two sets of stirring blades; when the reversing roller rotates, the stirring blades guide the dye liquor along the axial direction of the reversing roller.

[0009] By adopting the above technical solution, two sets of stirring blades are installed on the heat exchange roller to increase the stirring range and improve the fluidity of the dye liquor. Furthermore, when the reversing roller rotates, the two sets of stirring blades guide the flow of the dye liquor, causing it to flow along the axial direction of the reversing roller, thus ensuring sufficient contact between the dye liquor and the fabric surface and improving the dyeing effect.

[0010] Optionally, the two sets of stirring blades of the reversing roller are arranged in opposite directions to guide the dye liquor, and the rotation directions of two vertically adjacent reversing rollers are arranged in opposite directions.

[0011] By adopting the above technical solution, the two sets of stirring blades of the reversing roller are arranged in opposite directions to guide the dye liquor, so that when the reversing roller rotates, the dye liquor can move closer to or away from the winding area. The rotation directions of two vertically adjacent reversing rollers are arranged in opposite directions, that is, if the stirring blades of one reversing roller guide the dye liquor closer to the winding area, the stirring blades of the other reversing roller guide the dye liquor away from the winding area. The two flow directions are opposite, which improves the uniformity of the dye and thus improves the dyeing effect.

[0012] Optionally, the portion of the fabric located between two vertically adjacent reversing rollers is a reversing section, and a reversing zone is formed between two adjacent reversing sections; the reversing zone is provided with a support assembly for intermittently expanding or shrinking the reversing zone.

[0013] By adopting the above technical solution, the reversing zone is intermittently forced to expand or shrink by the support component, so that the reversing zone can achieve a "breathing" effect. When the reversing zone expands, the dye liquid is "absorbed" into the reversing zone, and when the reversing zone shrinks, the dye liquid is "exhaled", thereby increasing the flow rate of the dye liquid in the reversing zone and thus improving the dyeing effect.

[0014] Optionally, the supporting assembly includes supporting bars, driving bars, and driving components. Two supporting bars and two driving bars are provided, and both are slidably installed within the reversing zone. The two supporting bars correspond to two reversing segments in the reversing zone, and each supporting bar has a through-passage for the reversing segment to pass through. A connecting rod is provided between each driving bar and the two supporting bars, with one end hinged to the driving bar and the other end hinged to the supporting bar. When the two driving bars approach each other, the two supporting bars move away from each other. The driving component is provided on the two driving bars to drive them to approach or move away from each other.

[0015] By adopting the above technical solution, during fabric conveying, the two drive bars are driven to slide by the drive component. When the two drive bars approach each other, under the action of the connecting rod, the two supporting bars can move away from each other and open up the two reversing sections to expand the reversing zone. When the two drive bars move away from each other, under the action of the connecting rod, the two supporting bars can move closer to each other to reduce the reversing zone, thereby enabling the reversing zone to achieve a "breathing" effect and improve the dyeing effect.

[0016] Optionally, the rotation directions of two vertically adjacent reversing rollers are arranged in opposite directions. The driving component includes a first driving cam and a return spring. There are two first driving cams, which are respectively disposed on the outer peripheral walls of two vertically adjacent reversing rollers. The two first driving cams are correspondingly disposed with two driving bars. When the fabric is conveyed, the first driving cams of the two vertically adjacent reversing rollers force the two driving bars to move closer to each other. The return spring is disposed between the two driving bars. Under normal conditions, the return spring forces the two driving bars to move away from each other.

[0017] By adopting the above technical solution, under normal conditions, the return spring forces the two drive bars to move away from each other, that is, forces the two supporting bars to move closer together, thereby reducing the reversing zone. During fabric conveying, the first drive cams of the two vertically adjacent reversing rollers can push the two drive bars respectively, causing the two drive bars to move closer together, that is, forcing the two supporting bars to move away from each other, thereby expanding the reversing zone. As the reversing rollers continue to rotate, the first drive cams can intermittently push the drive bars, which, in conjunction with the return spring, achieves a "breathing" effect in the reversing zone.

[0018] Optionally, two vertically adjacent reversing rollers are arranged in opposite directions of rotation, and two horizontally adjacent reversing rollers are arranged in the same direction of rotation; the driving component includes a second driving cam, the number of the second driving cams is arranged corresponding to the number of reversing rollers in the reversing zone, and each second driving cam is arranged on the outer peripheral wall of the corresponding reversing roller; during fabric conveying, the second driving cams of two horizontally adjacent reversing rollers push the driving strip in opposite directions.

[0019] By adopting the above technical solution, the rotation directions of two horizontally adjacent reversing rollers are the same, and the second drive cams of the two horizontally adjacent reversing rollers push the drive bar in opposite directions. That is, when the fabric is conveyed, the drive bar can slide back and forth to achieve the "breathing" effect of the reversing zone.

[0020] Optionally, the support bars are rotatably mounted with push rods and pull rods, and the push rods and pull rods are spaced apart to form the through-channel.

[0021] By adopting the above technical solution, when the two opposing support bars are far apart, the opposing support bars push the reversing section through the push rod to expand the reversing area; when the two opposing support bars are close to each other, the opposing support bars pull the reversing section through the pull rod to shrink the reversing area, thereby achieving the "breathing" effect of the reversing area.

[0022] Optionally, the outer diameter of the push rod gradually decreases from the middle position to both ends, and the outer diameter of the pull rod gradually decreases from the middle position to both ends.

[0023] By adopting the above technical solution, the outer diameters of both the push rod and the pull rod are set to gradually decrease from the middle to both ends. This allows the push rod to push the reversing section or the pull rod to pull the reversing section, guiding the reversing section to lay out as flat as possible, reducing the possibility of wrinkles during fabric conveying, and thus improving the dyeing effect of the fabric. In addition, by changing the outer diameter, the pushing resistance of the push rod on the reversing section and the pulling resistance of the pull rod on the reversing section can be reduced to a certain extent.

[0024] Secondly, the dyeing method for abrasion-resistant and wrinkle-resistant polyester fabric provided in this application adopts the following technical solution: A dyeing method for wear-resistant and wrinkle-resistant polyester fabric includes the following steps: S1, pretreatment: removing impurities from the fabric; S2, dyeing: placing the fabric in a dyeing vat for dyeing; S3, posttreatment: washing the fabric; S4, drying.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Using reversing rollers and stirring blades, the fabric to be dyed is wound around one of the take-up and release rollers. After passing through multiple reversing rollers in the dyeing zone, the fabric connects to another take-up and release roller. A lowering frame places the fabric into the dyeing vat. A rotating component drives the take-up and release rollers to rotate, transferring the fabric from one roller to another. By switching the rotation direction of the take-up and release rollers, the fabric can be repeatedly switched between the two rollers. When the fabric passes through the dyeing zone, the multiple reversing rollers separate the fabric, reducing the possibility of uneven dyeing caused by the fabric surfaces sticking together. Furthermore, the rotation of the reversing rollers, along with the stirring blades, agitates the dye liquor as the fabric passes through the dyeing zone, reducing the possibility of dye precipitation or excessively high local concentrations, thereby improving the dyeing effect. 2. By setting the support components, the reversing zone is intermittently forced to expand or shrink, enabling the reversing zone to "breathe". When the reversing zone expands, the dye solution is "drawn" into the reversing zone, and when the reversing zone shrinks, the dye solution is "exhaled", which increases the flow rate of the dye solution in the reversing zone and thus improves the dyeing effect. 3. Through the configuration of the first drive cam and the return spring, under normal conditions, the return spring forces the two drive bars to move away from each other, that is, forces the two opposing support bars to move closer together, thereby reducing the reversing zone. During fabric conveying, the first drive cams of the two vertically adjacent reversing rollers can push the two drive bars respectively, causing the two drive bars to move closer together, that is, forcing the two opposing support bars to move away from each other, thereby expanding the reversing zone. As the reversing rollers continue to rotate, the first drive cam can intermittently push the drive bars, which, in conjunction with the return spring, achieves a "breathing" effect in the reversing zone.

[0028] The following combination Figures 1-7 This application will be described in further detail.

[0029] Example 1: This application discloses an integrated dyeing device for wear-resistant and wrinkle-resistant polyester fabric.

[0030] Reference Figure 1 , Figure 2 An integrated dyeing device for wear-resistant and wrinkle-resistant polyester fabric includes a dyeing vat 1 and a lifting frame 2. The dyeing vat 1 is filled with dye liquor for dyeing polyester fabric 6. The lifting frame 2 is slidably installed on the dyeing vat 1 so that it can be raised and lowered. In this embodiment, the lifting frame 2 is driven by a gantry crane (the gantry crane can be an electric hoist, which is not shown in the figure).

[0031] Two take-up and release rollers 3 are rotatably mounted on the side wall of the lifting frame 2. The take-up and release rollers 3 are used for winding the fabric 6. The fabric 6 can be connected to the outer peripheral wall of the take-up and release rollers 3 by clamping. In other embodiments, the fabric 6 can also be connected to the outer peripheral wall of the take-up and release rollers 3 by binding. The two take-up and release rollers 3 are spaced apart in the horizontal direction. The lifting frame 2 is provided with a rotating component for driving the take-up and release rollers 3 to rotate.

[0032] In this embodiment, the rotating frame is configured as a rotating motor 22, which is fixedly mounted on the lifting frame 2. A sealing housing 23 is installed on the side wall of the lifting frame 2. The output shaft of the rotating motor 22 and one end of the take-up and untake-down roller 3 are both inserted into the sealing housing 23. A belt is installed inside the sealing housing 23 (belt drive is prior art, and its specific structure will not be described in detail here, nor is it shown in the figure). The output shaft of the rotating motor 22 and the take-up and untake-down roller 3 are connected in series by the belt so that the rotating motor 22 can drive the take-up and untake-down roller 3 to rotate.

[0033] Reference Figure 2 , Figure 3In this embodiment, the area between the two take-up and release rollers 3 is defined as the dyeing area 21. The lifting frame 2 is rotatably mounted on the side wall of the dyeing area 21 with multiple reversing rollers 4 for the fabric 6 to be wound. The fabric 6 is wound around the multiple reversing rollers 4 in sequence and is wound in a serpentine pattern in the dyeing area 21. When the lifting frame 2 descends and moves into the dyeing vat 1, both the take-up and release rollers 3 and the reversing rollers 4 are immersed in the dyeing liquid of the dyeing vat 1.

[0034] Reference Figure 2 , Figure 4 Each reversing roller 4 has stirring blades 41 installed on its outer peripheral wall. Two sets of stirring blades 41 are spaced apart along the axial direction of the reversing roller 4, forming a winding area 42 for the fabric 6 to be wound around. When the reversing roller 4 rotates, the stirring blades 41 guide the dye liquor along the axial direction of the reversing roller 4. It should be noted that in this embodiment, the two sets of stirring blades 41 of the reversing roller 4 are arranged in opposite directions to guide the dye liquor; two horizontally adjacent reversing rollers 4 rotate in the same direction; and two vertically adjacent reversing rollers 4 rotate in opposite directions.

[0035] Specifically, when the upper reversing roller 4 rotates, the two sets of stirring blades 41 of the upper reversing roller 4 guide the dye liquor to the side away from the winding area 42; while when the lower reversing roller 4 rotates, the two sets of stirring blades 41 of the lower reversing roller 4 guide the dye liquor to the side closer to the winding area 42; when the take-up and release roller 3 reverses direction, the guiding direction of the stirring blades 41 of the upper reversing roller 4 and the stirring blades 41 of the lower reversing roller 4 is opposite.

[0036] In this embodiment, stirring blades 41 can also be installed at the bottom of the dyeing vat 1 to further improve the stirring effect at the bottom of the dyeing vat 1 and reduce the possibility of dye sedimentation. In addition, depending on the number of reversing rollers 4, the reversing rollers 4 and the take-up and release rollers 3 can also be connected in series by belts to enable the reversing rollers 4 to achieve the effect of "active" rotation, thereby improving the conveying effect on the fabric 6.

[0037] The implementation principle of Embodiment 1 of this application is as follows: The fabric 6 to be dyed is wound around one of the take-up and release rollers 3. After multiple reversing rollers 4 are sequentially wound around the fabric 6 in the dyeing zone 21, it is connected to another take-up and release roller 3. The lifting frame 2 is lowered to place the fabric 6 into the dyeing vat 1. Then, the take-up and release rollers 3 are driven to rotate to transfer the fabric 6 from one take-up and release roller 3 to another. By switching the rotation direction of the take-up and release rollers 3, the fabric 6 can be switched back and forth between the two take-up and release rollers 3. When the fabric 6 passes through the dyeing zone 21, the arrangement of multiple reversing rollers 4 can separate the fabric 6, reducing the possibility of uneven dyeing caused by the fabric 6 surfaces sticking together.

[0038] When fabric 6 passes through dyeing zone 21, the rotation of reversing roller 4 can agitate the dye liquor through stirring blades 41, reducing the possibility of dye precipitation or excessive local concentration, thereby improving the dyeing effect of fabric 6. Furthermore, when reversing roller 4 rotates, the two sets of stirring blades 41 of reversing roller 4 can guide the flow direction of dye liquor, so that dye liquor flows along the axial direction of reversing roller 4, thereby allowing dye liquor to fully contact the surface of fabric 6 and improving the dyeing effect.

[0039] Example 2: This application discloses an integrated dyeing device for wear-resistant and wrinkle-resistant polyester fabric.

[0040] The integrated dyeing apparatus for wear-resistant and wrinkle-resistant polyester fabric disclosed in this application differs from Embodiment 1 in that: Reference Figure 5 , Figure 6 In this embodiment, for ease of description, the portion of the fabric 6 located between two vertically adjacent reversing rollers 4 is defined as the reversing segment 61, and the area between two adjacent reversing segments 61 is defined as the reversing zone 62. Multiple reversing rollers 4 cause the fabric 6 to form multiple reversing zones 62. A support assembly 5 is provided within the reversing zone 62. The support assembly 5 is used to intermittently expand or shrink the reversing zone 62. It should also be noted that in this embodiment, the number of support assemblies 5 is less than the number of reversing zones 62, and the multiple support assemblies 5 are spaced apart along the multiple reversing zones 62.

[0041] The support assembly 5 includes support bars 51, drive bars 52, and drive components. In this embodiment, there are two support bars 51 and two drive bars 52. Both support bars 51 and drive bars 52 are located in the reversing zone 62. The side wall of the lifting frame 2 (the lifting frame 2 is not shown in the figure of this embodiment) is equipped with a first mounting bar 24. One end of each of the two support bars 51 extends out of the reversing zone 62 and is slidably mounted on the side wall of the first mounting bar 24 so that it can slide in the horizontal direction.

[0042] The side wall of the lifting frame 2 is equipped with a second mounting strip 25. One end of the second mounting strip 25 extends into the reversing area 62. The number of second mounting strips 25 in the reversing area 62 corresponds to the number of drive strips 52. Each drive strip 52 is slidably mounted on the corresponding second mounting strip 25 so that it can slide in the vertical direction.

[0043] Each drive bar 52 is connected to two supporting bars 51 by a connecting rod 53. One end of the connecting rod 53 is hinged to the drive bar 52 and the other end is hinged to the supporting bar 51. When the two drive bars 52 approach each other in the vertical direction, the two supporting bars 51 move away from each other. When the two drive bars 52 move away from each other in the vertical direction, the two supporting bars 51 approach each other.

[0044] Reference Figure 5 , Figure 6Each of the support bars 51 is rotatably mounted with a push rod 512 and a pull rod 513. The pull rod 513 is located on the side of the push rod 512 away from the support bar 51. The push rod 512 and the pull rod 513 are spaced apart to form a through channel 511. The through channels 511 of the two support bars 51 are corresponding to the two reversing sections 61. The through channels 511 of each pair of support bars 51 are used for the corresponding reversing section 61 to pass through. In this embodiment, the outer diameter of the push rod 512 gradually decreases from the middle position to both ends, and the outer diameter of the pull rod 513 gradually decreases from the middle position to both ends.

[0045] A driving element is disposed on two driving bars 52 to drive the two driving bars 52 to move closer to each other or further apart. In this embodiment, the driving element includes a first driving cam 54 and a return spring 55. Two first driving cams 54 are disposed, and the two first driving cams 54 are respectively installed on the outer peripheral walls of two vertically adjacent reversing rollers 4. The two first driving cams 54 are correspondingly disposed with the two driving bars 52. When the fabric 6 is conveyed, the first driving cams 54 of the two vertically adjacent reversing rollers 4 simultaneously force the two driving bars 52 to move closer to each other. The ends of the two driving bars 52 that move away from each other each have a first pushing strip 521 for the first driving cam 54 to push. The two ends of the return spring 55 are respectively fixedly connected to the two driving bars 52. Under normal conditions, the return spring 55 forces the two driving bars 52 to move away from each other.

[0046] The implementation principle of Embodiment 2 of this application is as follows: When the fabric 6 is conveyed (i.e., when the reversing roller 4 rotates), the two drive bars 52 are pushed closer to each other by their respective first drive cams 54, thereby driving the two supporting bars 51 to move away from each other under the action of the connecting rod 53, so as to open the two reversing sections 61 and expand the reversing area 62. As the reversing roller 4 rotates, when the first drive cam 54 disengages from the corresponding drive bar 52, the two drive bars 52 move away from each other under the action of the return spring 55, driving the two supporting bars 51 to move closer to each other, thereby reducing the reversing area 62.

[0047] As the reversing roller 4 continues to rotate, the reversing zone 62 is expanded or contracted intermittently, thereby enabling the reversing zone 62 to "breathe". When the reversing zone 62 expands, the dye liquor is "drawn" into the reversing zone 62, and when the reversing zone 62 contracts, the dye liquor is "exhaled", which increases the flow rate of the dye liquor in the reversing zone 62 and thus improves the dyeing effect.

[0048] In addition, the first drive cam 54 forces the two drive bars 52 to move closer to each other, causing the return spring 55 to contract and become elastic. As the reversing roller 4 rotates, when the first drive cam 54 disengages from the corresponding drive bar 52, the elastic force of the return spring 55 is released, causing the support bar 51 to oscillate, which to a certain extent increases the flow speed of the dye liquor in the reversing zone 62, thereby improving the dyeing uniformity.

[0049] Example 3: This application discloses an integrated dyeing device for wear-resistant and wrinkle-resistant polyester fabric.

[0050] The difference between the integrated dyeing device for wear-resistant and wrinkle-resistant polyester fabric disclosed in this application embodiment and Embodiment 2 is as follows: Reference Figure 7 In this embodiment, the driving component includes a second driving cam 56. The number of second driving cams 56 corresponds to the number of reversing rollers 4 in the reversing zone 62 (i.e., there are four second driving cams 56). Each second driving cam 56 is installed on the outer peripheral wall of the corresponding reversing roller 4. When the fabric 6 is conveyed, the second driving cams 56 of two horizontally adjacent reversing rollers 4 push the driving strip 52 in opposite directions (i.e., during the rotation of two horizontally adjacent reversing rollers 4, the second driving cam 56 of one reversing roller 4 is used to push the driving strip 52 to slide closer to the center of the reversing zone 62, while the second driving cam 56 of the other reversing roller 4 is used to push the driving strip 52 to slide away from the center of the reversing zone 62). The ends of the two driving strips 52 that are far apart from each other have a second pushing strip 522 for the second driving cam 56 to push.

[0051] The implementation principle of Embodiment 3 of this application is as follows: the rotation direction of two horizontally adjacent reversing rollers 4 is the same, so that the second drive cam 56 of the two horizontally adjacent reversing rollers 4 pushes the drive bar 52 in opposite directions. That is, when the fabric 6 is conveyed, the two horizontally adjacent reversing rollers 4 can force the corresponding drive bar 52 to slide back and forth, thereby intermittently expanding or shrinking the reversing area 62 and realizing the "breathing" effect of the reversing area 62.

[0052] Example 4: This application also discloses a dyeing method for abrasion-resistant and wrinkle-resistant polyester fabric.

[0053] A dyeing method for abrasion-resistant and wrinkle-resistant polyester fabric specifically includes the following steps: S1. Pretreatment: Remove impurities from fabric 6.

[0054] S2. Dyeing: a. Dye solution preparation: Weigh the dye and auxiliaries according to the required color of fabric 6, add them to water, and stir evenly to prepare the dye solution. b. Dyeing: Place the pretreated fabric 6 in the dyeing vat 1 and dye it under certain temperature, time, and pH conditions. Stir during the dyeing process to ensure that the fabric 6 is evenly dyed.

[0055] S3. Post-treatment: Wash the dyed fabric 6 multiple times to remove unfixed dyes and auxiliaries from the surface of the fabric 6.

[0056] S4. Drying: Dry the post-treated fabric 6 to remove moisture and bring the fabric 6 to the specified moisture content.

[0057] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
