Description

Technical Field

[0001] The present invention relates to the technical field of textile dyeing, and particularly to a clean dyeing process for cotton textiles. Background Art

[0002] Cotton textiles are necessities in people's daily lives and have a wide range of uses in people's clothing, bedding, indoor supplies, interior decoration, etc. Among them, dyeing is a key link in the printing and dyeing process of cotton textiles. It is a process of borrowing the physical or chemical combination of dyes and fibers, or generating insoluble colored substances on the fibers by chemical methods to make the entire textile have a certain color.

[0003] After the embryo dyeing is completed, a water washing process is still required. Although the disperse dye molecules are small, it cannot be guaranteed that all the dye molecules enter the fiber interior during dyeing. Some disperse dyes will adhere to the fiber surface. If these floating colors are not removed, the fastness will be poor. At this time, by using a strong reducing agent in the reduction cleaning to destroy the dye molecules that have not entered the fiber interior, the fastness can be improved and the color shade can be improved.

[0004] In the prior art, an embryo cloth dyeing treatment system and its dyeing method with the publication number of CN117845462A are provided. Through the setting of the water washing promoting mechanism, the driving component can drive the tensioning roller to lift in the water washing cavity to realize the tensioning or relaxation of the embryo cloth by the tensioning component. At the same time, when the tensioning component relaxes the embryo cloth, the driving component can drive the beating component to beat the embryo cloth to improve the water washing effect.

[0005] Although it can beat the embryo cloth during the water washing process to improve the water washing effect, there are still some defects in the actual processing. Since the cotton textiles after water washing and dyeing can only be beaten and cannot be fully kneaded, it cannot ensure that the dye molecules on the embryo cloth are completely washed away, and the uniformity of rinsing cannot be guaranteed, thus affecting the color fastness of dyeing and reducing the dyeing quality of the fabric.

[0006] Therefore, a clean dyeing process for cotton textiles is proposed to solve the above problems. Summary of the Invention

[0038] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0039] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed below.

[0040] As Figure 1-8 shown, a cleaning and dyeing process for cotton textiles includes the following steps:

[0041] Step 1: Pretreatment, performing degreasing, impurity removal, and pre-shrinking treatment on the fabric.

[0042] Step 2: Pretreatment before dyeing, soaking the fabric in the pretreatment solution before dyeing to remove residual impurities and grease on the surface of the fabric.

[0043] Step 3: Dyeing treatment, filling the fabric into the dyeing machine 1, and by controlling parameters such as temperature, time, and concentration, making the dye penetrate into the fabric fibers to achieve the dyeing effect.

[0044] Step 4: Post-treatment after dyeing, passing the dyed fabric through the water washing machine 2 for washing, and then performing drying and other treatments.

[0045] Step 5: Fixing treatment, performing fixing treatment on the dyed fabric to improve the durability of the dyeing effect.

[0046] Step 6: Post-finishing, finishing the dyed fabric, including treatments such as leveling, calendering, and ironing.

[0047] The water washing machine 2 in Step 4 includes a frame body 3 and a fabric conveying mechanism 4. The fabric conveying mechanism 4 is arranged on one side of the frame body 3 away from the dyeing machine 1. The conveying mechanism 4 is mainly composed of structures such as a motor, a transmission roller, and gears, and can provide a pulling force for the blank to ensure that the blank can pass through the water washing machine 2. Through grooves 5 are opened on both sides of the frame body 3, and a pair of feeding rollers 6 are rotatably connected to the inner sides of the through grooves 5. Side rollers 7, an upper roller 8, and a lower roller 9 are respectively rotatably connected to the inner side of the frame body 3. After the fabric passes through the dyeing machine 1, it passes through between one pair of feeding rollers 6, then sequentially bypasses the side roller 7, the upper roller 8, and the lower roller 9 and passes through between the other pair of feeding rollers 6, and then enters the next process through the fabric conveying mechanism 4. A rubbing plate 10 is fixedly connected to the inner side of the frame body 3 and between the upper roller 8 and the lower roller 9. A number of rubbing grooves 11 are opened on the side wall of the rubbing plate 10, and a rubbing mechanism is provided inside the frame body 3.

[0048] The kneading mechanism includes a pair of electric telescopic cylinders 12. Above the kneading plate 10 at the top of the frame 3, there is a fixed support frame 13. The electric telescopic cylinders 12 are fixedly connected to the top end of the support frame 13. Inside the frame 3, there is a sliding connection with a fixed frame 14. On the side of the fixed frame 14 close to the kneading plate 10, there are three rotating discs 15 rotatably connected through it. On the side walls of the three rotating discs 15, there are fixedly connected several kneading blocks 16. On the side walls of the rotating discs 15, there are rotating rods 31. On the outer walls of the rotating rods 31, there are fixedly connected toothed rings 17 that mesh with each other. Between the rotating discs 15 and the rotating rods 31, there is an adjusting mechanism;

[0049] On the outer wall of the middle rotating rod 31, there is a fixedly connected winding roller 18. Inside the winding roller 18, there is a winding rope 19. One end of the winding rope 19 is fixedly connected to the outer wall of the winding roller 18. At the top of the fixed frame 14 and above the winding roller 18, there is an opening 20. The other end of the winding rope 19 passes through the opening 20 and is fixedly connected to the bottom of the support frame 13. Between the winding roller 18 and the fixed frame 14, there is a volute spring 21. One end of the volute spring 21 is fixedly connected to the side wall of the winding roller 18, and the other end of the volute spring 21 is fixedly connected to the inside of the fixed frame 14;

[0050] To improve the service life of the device, at both ends inside the opening 20, there are rotatably connected guiding rollers 22. Through the setting of the guiding rollers 22, it can play a protective role when the winding rope 19 passes through the opening 20, avoiding the winding rope 19 from contacting the opening 20, which may cause wear of the winding rope 19 in the long term and affect the service life of the equipment. And at the bottom of the fixed frame 14, there are several drain holes 28. Through the setting of the drain holes 28, it is convenient to drain the cleaning water that enters the fixed frame 14 from the opening 20, improving the practical performance of the device.

[0051] To avoid damaging the blank during the water washing process, on the top of the kneading plate 10, there is an indented groove 23. Inside the groove 23, there is a rotatably connected material passing roller 24. Through the setting of the groove 23 and the material passing roller 24, it can play a protective role when the blank passes through the upper roller 8 and is transmitted to the lower roller 9 and passes through the kneading plate 10, avoiding the blank directly contacting the edges and corners on the top of the kneading plate 10 and causing abrasion, which affects the production quality of the blank.

[0052] To be able to normally drain and discharge the cleaning water into and out of the frame 3, at the top end inside the frame 3, there is a water inlet pipe 25 with a valve fixedly connected through it. At the bottom end of the side wall of the frame 3, there is a drain pipe 26 with a valve fixedly connected through it. And the water inlet pipe 25 is connected to an external water source. Before the water washing of the blank, first open the valve on the water inlet pipe 25 to drain the cleaning water into the frame 3. When the production is over or when it is necessary to replace the cleaning water, open the valve on the drain pipe 26, and the cleaning water in the frame 3 can be quickly drained.

[0053] In order to automatically control the up and down movement of the electric telescopic cylinder 12, touch sensors 27 are fixedly connected through the inner side of the frame 3 and on both the upper and lower sides of the kneading plate 10. The touch sensors 27 are electrically connected to the electric telescopic cylinder 12 through a controller. Through the arrangement of the upper and lower touch sensors 27, when the electric telescopic cylinder 12 drives the fixed frame 14 to move up and down and touches the touch sensor 27, the touch sensor 27 can transmit a signal to the controller, and the controller controls the electric telescopic cylinder 12 to drive in the reverse direction, so as to drive the fixed frame 14 to reciprocate up and down beside the kneading plate 10, without manual operation, improving the automation efficiency of the device.

[0054] In order to adjust the distance between the kneading block 16 and the kneading plate 10 according to cotton textiles of different thicknesses, the adjusting mechanism includes an adjusting frame 29. The adjusting frame 29 is fixedly connected to the side wall of the fixed frame 14, and the side wall of the rotating rod 31 passes through the side wall of the fixed frame 14 and is arranged inside the adjusting frame 29. A rectangular groove 30 is opened inside the rotating rod 31. A rectangular block 32 is fixedly connected to the side wall of the rotating disk 15, and the rectangular block 32 is slidably connected inside the rectangular groove 30.

[0055] The side wall of the rectangular block 32 is rotatably connected to a round rod 33 and passes through the side wall of the rotating rod 31. Adjusting blocks 34 are fixedly connected to the side walls of the round rod 33, and the adjusting blocks 34 are slidably connected to the inner bottom end of the adjusting frame 29. An inclined groove 35 is opened at the top of the adjusting block 34. A right-angle block 36 is slidably connected inside the adjusting frame 29 and above the inclined groove 35, and the inclined surface of the right-angle block 36 is mutually attached to the inclined groove 35. A screw rod 37 is threadedly connected through the top of the adjusting frame 29, and the bottom of the screw rod 37 is rotatably connected to the top end of the right-angle block 36. Springs 38 are fixedly connected between the adjusting blocks 34 and the adjusting frame 29. Through the arrangement of the springs 38, when the right-angle block 36 moves upward to relieve the extrusion of the adjusting block 34, the adjusting block 34 can be quickly pulled back to its original position.

[0056] In order to improve the stability during the operation of the device, inwardly recessed guiding grooves 39 are opened at both ends inside the adjusting frame 29. Guiding blocks 40 are fixedly connected to both sides of the right-angle block 36 and are slidably connected inside the guiding grooves 39. Through the arrangement of the guiding blocks 40 and the guiding grooves 39, the up and down sliding positions of the right-angle block 36 can be restricted, and at the same time, it is ensured that when the screw rod 37 moves spirally, the right-angle block 36 will not be driven to rotate, thereby improving the stability during the adjustment process.

[0057] When the blank is being cleaned by the water washing machine 2 after being dyed by the dyeing machine 1, the electric telescopic cylinder 12 is controlled to start and drive the fixed frame 14 to slide downward, thereby driving the rotating disk 15 to slide downward. The blank is squeezed into the rubbing groove 11 on the rubbing plate 10 by the rubbing block 16 to achieve the preliminary rubbing and cleaning of the blank. During this process, due to the downward sliding of the fixed frame 14, one end of the pulling rope 19 is fixed inside the support frame 13, so the pulling rope 19 will gradually be pulled out from the winding roller 18. And the other end of the pulling rope 19 is fixed on the winding roller 18. Therefore, the gradual pulling out of the pulling rope 19 will drive the winding roller 18 to rotate, and at the same time drive the rotating rod 31 to rotate;

[0058] Meanwhile, since one end of the scroll spring 21 is fixed on the side wall of the winding roller 18 and the other end is fixed inside the fixed frame 14, through the rotation of the winding roller 18, the scroll spring 21 will be gradually compressed, and then drive the middle gear ring 17 to rotate. Subsequently, drive the two meshing gear rings 17 on both sides to rotate simultaneously, and then drive the three rotating rods 31 to rotate simultaneously. Then, since the rectangular block 32 fixedly connected to the side wall of the rotating disk 15 is inserted into the rectangular groove 30, it will drive the rotating disk 15 to rotate simultaneously, and then drive multiple rubbing blocks 16 to rotate and rub the surface of the blank while descending, achieving the simulation of the rubbing method to improve the sufficient degree of contact between the cleaning liquid and the blank, thereby increasing the color fastness after dyeing and improving the dyeing quality. Finally, when the electric telescopic cylinder 12 drives the fixed frame 14 to move to the lowest position of the rubbing plate 10, control the electric telescopic cylinder 12 to move upward and repeat the above operations in reverse to achieve the comprehensive rubbing and cleaning of the passing blank.

[0059] When it is necessary to adjust the distance between the rubbing block 16 and the rubbing plate 10 according to cotton textiles of different thicknesses, first rotate the screw rod 37 to spiral downward, and then push the right-angle block 36 to slide downward. Thus, the inclined plane of the right-angle block 36 squeezes the inclined groove 35 to make the adjusting block 34 slide, and at the same time gradually stretch the spring 38. Then, push the rectangular block 32 to slide in the rectangular groove 30 through the round rod 33 to achieve the position movement of the rotating disk 15, and then adjust the distance between the rubbing block 16 and the rubbing plate 10, so as to adjust the rubbing effect of cotton textiles of different thicknesses and improve the applicable range of the device.
