Description

Technical Field

[0001] The invention relates to the technical field of textile printing and dyeing, and in particular to a soaking device and a process for improving the staining fastness of wool fabrics. Background Art

[0002] For clothes with multiple colors, different compositions and obvious differences in shades, the dye will diffuse from the darker areas to the lighter areas during the washing process. We call this phenomenon of the fabric staining, and the ability of the fabric to resist staining is called staining fastness.

[0003] In order to improve the color uniformity of wool fabric products and the tightness of the combination between wool fabric fibers and dyes, wool yarns are usually dyed after they are produced. There are currently three main ways to dye wool yarns: hank dyeing, package dyeing and warp dyeing. When performing package dyeing, the wool yarn needs to be wound on a loose package with holes to form a package yarn, and then the loose package is placed on the outside of the beams and columns of the yarn-carrying tray. After all the beams and columns are filled with loose packages, the yarn-carrying tray is moved to the dyeing cylinder for dyeing. After the wool yarn is dyed, it needs to be dried and fixed. The fixing agent is used to strengthen the combination of the dye and the wool yarn. During the fixing process, It is necessary to make the fixing agent completely immersed in the cheese yarn, but because several cheese yarns are stacked and arranged on the beams, the upper and lower sides of adjacent cheese yarns are fitted together, so that all the cheese yarns on the same beam column form a whole. In this case, it takes a long time for the fixing agent to penetrate into the cheese yarn. In order to shorten the above time, a spring is usually placed between two adjacent cheese yarns or the height of the wool yarn on the loose cone is made lower than the height of the loose cone, so that there is a gap between the wool yarns of two adjacent cheese yarns, which is convenient for the immersion of the fixing agent. However, the above two methods, one, increase the step of sleeve the cheese yarn on the beam column, which reduces the efficiency of the color fixing work, and the other, increase the number of loose cones required, which increases the cost. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will be combined with the attached Figure 1 To Attachment Fig.11 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. 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 creative work are within the scope of protection of the present invention.

[0022] When the cheese yarn is subjected to the color fixing treatment, since several cheese yarns are stacked and arranged on the beams, the upper and lower sides of adjacent cheese yarns are fitted together, so that all the cheese yarns on the same beam column form a whole. In this case, it takes a long time for the color fixing agent to penetrate into the cheese yarn. In order to shorten the above time, a spring is usually placed between two adjacent cheese yarns or the height of the wool yarn on the loose cone is made lower than the height of the loose cone, so that there is a gap between the wool yarns (hereinafter referred to as yarn) of two adjacent cheese yarns, which is convenient for the penetration of the color fixing agent. However, the above two methods, one, increase the step of sleeved the cheese yarn on the beam column, which reduces the efficiency of the color fixing work, and the other, increase the number of required loose cones, which increases the cost.

[0023] Example 1: A soaking device for improving the color fastness of wool fabrics, please refer to Figure 1-Figure 4, including a soaking cylinder 1, a top cover 2 is installed on the upper side of the soaking cylinder 1, a circulating pump 3 is installed at the lower part of the soaking cylinder 1 (the circulating pump 3 is an existing device and is not specifically shown in the attached figure), the circulating pump 3 is fixedly connected and connected with six annularly distributed connecting pipes 4, a yarn loading disc 5 is arranged outside the soaking cylinder 1, and the yarn loading disc 5 is provided with six annularly distributed connecting holes 501 and six annularly distributed liquid extraction holes 502, the connecting pipe 4 is slidably matched with the corresponding connecting holes 501, and the liquid extraction holes 502 are connected and matched with the circulating pump 3, so as to make The circulation pump 3 is connected to the space above the yarn-carrying disc 5 through the adjacent liquid extraction holes 502. A traction shaft 6 is provided in the middle of the yarn-carrying disc 5. A hanging hole combined with a hanger is provided on the upper side of the traction shaft 6. Six beams 7 distributed in an annular manner are fixedly connected to the upper side of the yarn-carrying disc 5. Several groups of inner punching holes 701 distributed in an equidistant manner are provided on the beams 7 (four groups of inner punching holes 701 are used as an example for explanation in the present invention). Each group of inner punching holes 701 includes six inner punching holes 701 distributed in an annular manner. The inner punching holes 701 are connected to the interior of the adjacent beams 7. The liquid in the beam column 7 is sprayed out through the adjacent inner punching holes 701. The central angle of the inner punching holes 701 corresponding to the central axis of the adjacent beam column 7 is proportional to the height of the inner punching holes 701, which is used to make the flow rates at different heights of the beam column 7 tend to be equal. The positions near the lower parts of the adjacent inner punching holes 701 on the beam column 7 are fixed with elastic flaps 8 through elastic sheets. The group of elastic flaps 8 distributed in an annular manner at the bottom are all in contact with the upper side of the yarn carrying disc 5, which is used to limit the maximum deformation and swing of the six elastic flaps 8 distributed in an annular manner at the bottom. The elastic folding piece 8 is fixedly connected to a limiting piece 9 at the bending part on one side of the central axis of the adjacent beam column 7 through an elastic piece. The limiting piece 9 is squeezed and matched with the adjacent beam column 7 to limit the deformation range of the adjacent elastic folding piece 8. The beam column 7 is provided with a ring-shaped and equidistantly distributed pull rope 10 and staggered with all the internal punching holes 701 thereon. The adjacent and non-contacting elastic folding pieces 8 and limiting pieces 9 on the same vertical line are respectively fixedly connected to the two ends of the adjacent pull rope 10, so as to pull the upper limiting piece 9 to swing by squeezing the lower elastic folding piece 8.

[0024] Please refer to Figure 5 and Figure 6 A central axis 11 is slidably and rotatably connected inside the beam column 7. The lower side of the central axis 11 is pressed and matched with the corresponding connecting pipe 4, which is used to make the central axis 11 move upward relative to the adjacent beam column 7. The central axis 11 is rotatably connected with four equidistant mounting rings 12. The mounting rings 12 are located at the upper part of the adjacent annularly distributed inner punching holes 701. The mounting rings 12 are fixedly connected with six annularly distributed extrusion plates 13 through elastic sheets. The extrusion plates 13 are in contact with the upper sides of the adjacent inner punching holes 701, which are used to make the extrusion plates 13 swing relative to the adjacent mounting rings 12 and make the extrusion plates 13 protrude from the adjacent inner punching holes 701.

[0025] Please refer to Figure 3 , Figure 5 and Figure 6A flexible tube 14 is fixedly connected to the side of the annularly distributed extrusion plate 13 away from the central axis of the adjacent mounting ring 12. The upper part of the flexible tube 14 is fixedly connected to the adjacent beam column 7. A flexible ring 15 is fixedly connected to the bending part of the annularly distributed elastic folding piece 8. The inner side of the flexible ring 15 is fixedly connected to the adjacent beam column 7. Both the flexible tube 14 and the flexible ring 15 are made of elastic material and are used to deform the adjacent flexible tube 14 and cover the gap between the cheese yarn and the adjacent beam column 7 after the extrusion plate 13 protrudes out of the adjacent inner punching hole 701.

[0026] Please refer to Figure 5-Figure 7 Three groups of annularly distributed diverter plates 16 are fixedly connected to the positions of the four adjacent and equidistantly distributed mounting rings 12 of the central axis 11. Each group of diverter plates 16 includes two symmetrically distributed diverter plates 16. The diverter plates 16 are composed of a baffle fixedly connected to the upper sides of two bent plates of the same shape. The length of the diverter plates 16 in the vertical direction is equal to the length of the inner punching hole 701 in the vertical direction, and is used to change the direction of liquid discharged through the inner punching hole 701.

[0027] Please refer to Figure 6 A fixing ring 17 is fixedly connected to the lower part of the central axis 11 , and a plurality of fan blades 18 distributed in an annular manner are fixedly connected to the fixing ring 17 . A spring is arranged between the upper side of the fixing ring 17 and the adjacent beam column 7 .

[0028] When the yarn is undergoing a color fixing treatment, the worker puts the dyed cheese yarn on the beam column 7 in turn (the following explanation will be given with the right beam column 7 and its adjacent parts). The first cheese yarn moves from top to bottom along the beam column 7 and contacts with four groups of annularly distributed elastic folds 8 in turn. When the cheese yarn contacts with the elastic folds 8, the cheese yarn squeezes the elastic folds 8 toward the direction close to the central axis of the beam column 7. The elastic folds 8 drive the adjacent elastic folds to deform. At the same time, the elastic folds 8 themselves deform (that is, the bending angle of the elastic folds 8 themselves increases), so that the diameter of the circle formed by the six annularly distributed elastic folds 8 is smaller than the inner diameter of the cheese yarn. Subsequently, the cheese yarn passes over the annularly distributed elastic folds 8 and continues to move downward. After the cheese yarn loses contact with the elastic folds 8, the elastic folds 8 are reset under the action of their own elastic action and the action of their adjacent elastic folds.

[0029] As the first cheese yarn moves downward, until it contacts the six elastic flaps 8 at the bottom, the above-mentioned steps of deforming the elastic flap 8 are repeated. As the elastic flap 8 is deformed, the lower end of the elastic flap 8 finally contacts the upper side of the yarn carrying disk 5. At this time, the elastic flap 8 stops deforming, and at the same time, the diameter of the circle formed by the six elastic flaps 8 is still larger than the inner diameter of the cheese yarn, thus preventing the cheese yarn from continuing to move downward. When the elastic flap 8 at the bottom is deformed, the elastic flap 8 at the bottom pulls the adjacent pull rope 10, so that the pull rope 10 pulls the limiting piece 9 of the second layer to swing, and the limiting piece 9 drives the adjacent elastic piece to bend, so that the distance between the limiting piece 9 and the beam column 7 is reduced. In the process of sleeved the second cheese yarn on the beam column 7, the second cheese yarn contacts the three elastic flaps in turn. The six elastic flaps 8 of the second layer are in contact with each other, and when the second cheese yarn contacts with the six elastic flaps 8 of the second layer, the elastic flaps 8 of the second layer and its adjacent elastic flaps are bent and deformed. However, since the distance between the limiting flaps 9 of the second layer and the beam 7 is reduced, when the elastic flaps 8 of the second layer swing and deform, the elastic flaps 8 of the second layer drive the adjacent limiting flaps 9 to swing and finally contact with the beam 7. At this time, the elastic flaps 8 of the second layer stop swinging due to the support of the adjacent limiting flaps 9. At the same time, the diameter of the circle formed by the six elastic flaps 8 of the second layer is larger than the inner diameter of the cheese yarn, thus preventing the second cheese yarn from continuing to move downward. The above steps are repeated until four cheese yarns are placed on all the beams 7 and there is a gap between two adjacent cheese yarns on the beams 7.

[0030] After all the cheese yarns are placed on all the beams 7, the worker opens the top cover 2 and connects the hook of the sling to the traction shaft 6. Then, the yarn carrier 5 is lifted into the soaking cylinder 1 by the sling, and the connecting tube 4 is inserted into the adjacent connecting hole 501. The color fixing agent is added into the soaking cylinder 1 until the color fixing agent covers all the cheese yarns. Then, the soaking cylinder 1 is sealed with the top cover 2. The worker starts the circulation pump 3. The circulation pump 3 absorbs the color fixing agent in the soaking cylinder 1 and transports it to the six connecting holes 501 through the six connecting tubes 4. The color fixing agent entering the connecting hole 501 flows along the adjacent beams 7 and is finally sprayed toward the inner wall of the adjacent cheese yarn through several adjacent inner punching holes 701, so as to immerse the cheese yarn from the inside to the outside.

[0031] In the prior art, the outer side of the beam 7 is in contact with the inner wall of the cheese, so that the position where the inner punching hole 701 is not provided on the beam 7 blocks the hole on the inner side of the cheese, resulting in a small contact area between the color fixing agent sprayed from the inner punching hole 701 and the inner wall of the cheese, which makes it impossible for the color fixing agent to quickly penetrate into the cheese. The solution is as follows: during the process of inserting the connecting tube 4 into the adjacent connecting hole 501, the connecting tube 4 contacts the adjacent central axis 11, causing the central axis 11 to stop moving. As the yarn carrying disc 5 continues to move downward, the beam 7 moves along the corresponding The adjacent center axis 11 moves downward and compresses the spring between the beam column 7 and the adjacent fixing ring 17. When the beam column 7 moves downward, the beam column 7 squeezes the adjacent squeezing plate 13 through the adjacent inner punching hole 701, twisting the elastic sheet adjacent to the squeezing plate 13, so that the squeezing plate 13 protrudes out of the adjacent beam column 7 and finally contacts the inner wall of the cheese (i.e., the inner wall of the loose cone), pushes the cheese to move, and makes the central axis of the cheese collinear with the central axis of the beam column 7 (at this time, the inner wall of the cheese is not in contact with the beam column 7, and there is a gap between the beam column 7 and the cheese).

[0032] When the color fixing agent flows in the beam 7, the fan blades 18 drive the fixing ring 17 and the central shaft 11 to rotate under the impact of the color fixing agent, and the central shaft 11 drives all the diverter plates 16 thereon to rotate circumferentially. At the same time, a part of the color fixing agent enters the diverter plate 16 from the lower side and flows out through the side of the diverter plate 16. When the color fixing agent flows out of the diverter plate 16, the diverter plate 16 guides the flow direction of the color fixing agent to change and sprays it toward the inner wall of the cheese yarn through the adjacent inner punching hole 701, so that the range of the inner punching hole 701 spraying the color fixing agent is increased, and the area of ​​the color fixing agent spraying toward the inner wall of the cheese yarn is increased, thereby accelerating the rate at which the color fixing agent immerses in the cheese yarn and improving the efficiency of the color fixing work. Another part of the color fixing agent continues to flow upward through the gap between the adjacent diverter plates 16.

[0033] During the swinging process of the squeezing plate 13, the squeezing plate 13 drives the adjacent flexible tube 14 to deform, so that the diameter of the lower part of the flexible tube 14 increases, and the upper side of the gap between the cheese yarn and the beam column 7 is blocked. At the same time, the flexible ring 15 blocks the lower side of the gap between the cheese yarn and the beam column 7, reducing the flow area of ​​the color fixing agent when it is discharged from the gap between the cheese yarn and the beam column 7, increasing the pressure of the color fixing agent in the gap, and accelerating the rate of penetration of the color fixing agent into the cheese yarn.

[0034] After the color fixing work is completed, the worker opens the top cover 2 and turns off the circulating pump 3, then uses the sling to take out the yarn carrier 5 from the soaking cylinder 1, and discharges the remaining color fixing agent in the soaking cylinder 1. In the process of taking out the yarn carrier 5 from the soaking cylinder 1, the beam column 7 first moves up along the adjacent central axis 11, so that the spring between the beam column 7 and the adjacent fixing ring 17 stretches and resets, and the inner punching hole 701 gradually loses the squeeze on the adjacent extrusion plate 13. The extrusion plate 13 is reset relative to the adjacent mounting ring 12 under the action of the adjacent elastic sheet, and the central axis 11 is reset relative to the beam column 7. Then the beam column 7 drives the adjacent central axis 11 and its adjacent parts to move up together.

[0035] After taking the yarn carrying plate 5 out of the soaking cylinder 1, the worker removes the cheese yarn mounted on the beam 7 from top to bottom. When the uppermost cheese yarn is removed, the cheese yarn first loses contact with the six adjacent elastic folds 8, so that the six elastic folds 8 recover their deformation. Then, when the second cheese yarn on the upper side is removed, the cheese yarn first loses contact with the six adjacent elastic folds 8 on its lower side, so that the six elastic folds 8 recover their deformation and loses traction on the adjacent pull ropes 10. The uppermost adjacent limiting pieces 9 swing and reset under the action of the adjacent elastic pieces. Then, the second cheese yarn on the upper side contacts the six elastic folds 8 on the upper side and squeezes the six elastic folds 8 to deform. The second cheese yarn is removed, and the above steps in this paragraph are repeated until all the cheese yarns are removed and the color fixing work is completed.

[0036] When fixing the color of the cheese yarn, there are gaps after the yarn is wound onto the loose cone. After the cheese yarn is immersed in the fixing agent, a bubble layer will be formed between the yarns, which hinders the infiltration of the external fixing agent. The existing method is to remove the bubble layer by applying stirring to make the fixing agent flow, but the efficiency of destroying the bubble layer by the flow of the fixing agent is low, which makes the overall fixing time long.

[0037] Example 2: Based on Example 1, please refer to Figure 8 and Fig. 9 , also includes six inner extrusion columns 19 distributed in an annular manner, the inner extrusion columns 19 are fixedly connected to the side of the traction shaft 6, the lower side of the soaking cylinder 1 is rotatably connected with a mounting member 20, and the upper side of the mounting member 20 is fixedly connected with six outer extrusion columns 21 distributed in an annular manner, a servo motor 22 is installed on the lower side of the soaking cylinder 1, the output shaft of the servo motor 22 passes through the lower part of the soaking cylinder 1 and is transmitted to the mounting member 20 by gears, a spline shaft 23 is rotatably connected to the middle part of the lower side of the soaking cylinder 1, the spline shaft 23 is spline-matched with the traction shaft 6, and a gear transmission is transmitted between the output shaft of the servo motor 22 and the spline shaft 23. After the servo motor 22 is started, the angular velocity of the spline shaft 23 is equal to that of the mounting member 20, and the rotation direction of the spline shaft 23 is opposite to that of the mounting member 20. After the yarn loading disc 5 is placed in the soaking cylinder 1, the yarn loading disc 5 blocks the yarn and impurities in the upper color fixing agent on the upper side of the yarn loading disc 5, so that the above-mentioned impurities cannot contact the gears and do not affect the transmission of the gears.

[0038] Please refer to Figure 8 , Fig. 9 and Fig.11Four groups of equally spaced limiters 24 are fixedly connected to the inner extrusion column 19 and the outer extrusion column 21. Each group of limiters 24 includes two limiters 24 symmetrically distributed up and down, and the distance between each group of limiters 24 is equal to the height of the cheese yarn. Extrusion surfaces 241 are provided on the opposite sides of the symmetrically distributed limiters 24 for extruding adjacent cheese yarns to prevent the yarns on the cheese yarns from spreading.

[0039] Please refer to Fig.10 The traction shaft 6 is rotatably connected to the yarn loading disk 5, and the lower limit sliding connection of the traction shaft 6 is provided with three friction blocks 25 distributed in an annular manner. The friction blocks 25 are frictionally matched with the yarn loading disk 5. Initially, the upper side of the friction blocks 25 is in contact with the yarn loading disk 5 to improve the stability of the traction shaft 6 and the yarn loading disk 5. The side of the friction block 25 close to the central axis of the traction shaft 6 is fixedly connected with an extrusion block 26, and the extrusion block 26 is semi-cylindrical. A spring is fixedly connected between the side of the extrusion block 26 away from the central axis of the traction shaft 6 and the traction shaft 6, and the extrusion block 26 is extrusion-matched with the spline shaft 23.

[0040] After all beams 7 are sleeved with cheese yarn, the steps of Example 1 are repeated. The worker places the yarn-carrying disc 5 into the soaking barrel 1. During the placement process, the traction shaft 6 contacts the spline shaft 23 and is spline-connected. At the same time, the spline shaft 23 contacts the three extrusion blocks 26 and squeezes the adjacent friction blocks 25 to move away from the central axis of the traction shaft 6, compressing the springs adjacent to the extrusion blocks 26, so that the friction blocks 25 lose contact with the yarn-carrying disc 5 (reducing the resistance of the subsequent rotation of the traction shaft 6 relative to the yarn-carrying disc 5). After the lower side of the yarn-carrying disc 5 contacts the lower side of the soaking barrel 1, the steps of Example 1 are repeated to close the top cover 2 and The steps of starting the circulation pump 3 and starting the servo motor 22, the output shaft of the servo motor 22 rotates in opposite directions at the same speed through the gear transmission mounting part 20 and the spline shaft 23, the mounting part 20 drives the six outer extrusion columns 21 thereon to rotate circumferentially, and at the same time the spline shaft 23 drives the traction shaft 6 to rotate through the spline, and the traction shaft 6 drives the six inner extrusion columns 19 thereon to rotate, the inner extrusion columns 19 and the outer extrusion columns 21 approach the cheese yarn at the same time, and finally contact with the symmetrical positions on the cheese yarn, as the inner extrusion columns 19 and the outer extrusion columns 21 rotate circumferentially, the two squeeze the cheese yarn together to deform, and squeeze out the gas inside the cheese yarn.

[0041] When the inner extrusion column 19 and the outer extrusion column 21 extrude the cheese yarn together, the upper and lower sides of the contact position of the cheese yarn and the two are respectively in contact with the adjacent limit members 24, and the upper and lower sides of the cheese yarn are respectively in contact with the upper and lower adjacent extrusion surfaces 241. Under the action of the extrusion surfaces 241, the height of the yarn on the cheese yarn is kept unchanged, that is, the yarn on the cheese yarn does not loosen. With the circumferential rotation of the inner extrusion column 19 and the outer extrusion column 21, the inner extrusion column 19 and the outer extrusion column 21 drive the cheese yarn to rotate together, and finally the inner extrusion column 19 and the outer extrusion column 21 lose contact with the cheese yarn. At this time, the cheese yarn is deformed and reset under the elastic action of the yarn. During the reset process of the cheese yarn, the external color fixing agent is sucked into the cheese yarn, thereby accelerating the rate at which the color fixing agent penetrates into the cheese yarn.

[0042] After the color fixation is completed, repeat the steps of Example 1 to take out the yarn loading disc 5. In the process of the yarn loading disc 5 moving upward relative to the soaking cylinder 1, the contact area between the traction shaft 6 and the spline shaft 23 gradually decreases until the two lose contact. At this time, the extrusion block 26 moves and resets under the action of the adjacent spring, and the extrusion block 26 drives the adjacent friction block 25 to move, so that the friction block 25 contacts and frictionally cooperates with the yarn loading disc 5 again, thereby increasing the friction resistance of rotation between the yarn loading disc 5 and the traction shaft 6, and improving the stability of the yarn loading disc 5 during lifting.

[0043] Example 3: Based on Example 2, please refer to Figure 1-Figure 11 , a soaking process for improving the color fastness of wool fabric, using a soaking device for improving the color fastness of wool fabric, the specific steps are as follows: S1: The cheese yarn is sleeved on the beam column 7, and the cheese yarn is fixed on the adjacent beam column 7 in layers by means of the elastic flaps 8 which are evenly distributed above and below, and then the yarn carrying disc 5 is hoisted into the soaking cylinder 1, so that the connecting pipe 4 is connected with the adjacent beam column 7, and the color fixing agent is added into the soaking cylinder 1, the traction shaft 6 contacts and splinedly connects with the spline shaft 23, the squeezing plate 13 straightens the cheese yarn, and the friction block 25 loses contact with the yarn carrying disc 5; S2: Start the circulation pump 3 and the servo motor 22, the circulation pump 3 transports the color fixing agent in the soaking cylinder 1 to the beam 7, and discharges it through the inner punching hole 701, and soaks the cheese from the inside to the outside; S3: The servo motor 22 drives the outer extrusion column 21 and the inner extrusion column 19 to rotate circumferentially, and the outer extrusion column 21 and the inner extrusion column 19 squeeze the cheese yarn and drive the cheese yarn to rotate. At the same time, the limiter 24 prevents the yarn on the cheese yarn from spreading; S4: Stop the circulation pump 3 and the servo motor 22, and take the yarn carrier 5 out of the soaking cylinder 1. The traction shaft 6 loses contact with the spline shaft 23, the friction block 25 contacts with the yarn carrier 5 again and frictionally fits, the extrusion plate 13 resets and loses contact with the cheese yarn, and the cheese yarn is removed from the beam 7.
