Description

Technical Field

[0001] The invention relates to the technical field of textile desizing, in particular to a fabric desizing process with high-efficiency water circulation. Background Art

[0002] Desizing is a crucial step in the production of textiles. Desizing refers to the process of removing the sizing agent on the fabric to improve the subsequent processing performance of the fabric. Before weaving, the warp yarn is usually treated with sizing to improve the breaking strength and abrasion resistance of the yarn. However, these sizing agents affect the wettability, dyeing uniformity and feel of the fabric, so they need to be removed in the subsequent process.

[0003] A Chinese patent application with application number 201810228280.X discloses a method for desizing a fabric, wherein the fabric to be treated is subjected to plasma treatment, drying treatment and desizing treatment in sequence while being conveyed on a conveying mechanism; wherein, before the plasma treatment, the moisture regain of the fabric is controlled to be 3%-8%, the speed at which the fabric moves on the conveying mechanism is 50-70 m / min, and during the drying treatment, the moisture regain of the plasma-treated fabric is controlled to be 2%-7%; the invention can realize continuous production of the plasma treatment and desizing treatment processes, and has the advantages of high desizing rate, fast desizing speed, and can greatly reduce the use of chemicals in the desizing solution and thus reduce pollution.

[0004] A Chinese patent with application number 202011251190.6 discloses a desizing and washing device for thicker fabrics, including a box body, a placement space is provided inside the box body, a cleaning mechanism is provided inside the placement space, and the cleaning mechanism includes a cleaning box fixedly connected to the lower inner wall of the placement space. The invention is provided with a cleaning mechanism, which can clean the surface of the fabric to prevent the fluff on the surface of the fabric from affecting the desizing effect. By tightening the fabric to the inlet of the suction box, the desizing agent is allowed to penetrate the fabric by suction. Even if the fabric is thick, a good desizing effect can be achieved, ensuring that the subsequent processing and printing and dyeing process can obtain high-quality products.

[0005] The traditional desizing process has problems such as high water consumption and low desizing efficiency. Furthermore, when desizing fabrics similar to the above-mentioned prior art, multiple transmission shafts are set in the desizing tank to tension the fabric and drive the fabric to move in the desizing tank, so that the desizing liquid and the fabric are fully in contact for desizing. However, during the contact between the fabric and the transmission shaft, if the surface of the transmission shaft becomes rough due to aging or absorption of foreign matter, it will scratch the fabric, causing the surface of the fabric to be damaged and unusable.

[0006] At the same time, in order to improve the desizing effect on the fabric, multiple desizing tanks are usually set up to desizing the fabric multiple times. If the desizing liquid in the same desizing tank is not replaced for a long time, its desizing ability for the fabric will decrease. If the desizing liquid is replaced frequently, it will cause unnecessary waste, which is not conducive to production. In addition, the desizing liquid will separate after standing for a long time, affecting the desizing effect on the fabric.

[0007] Therefore, it is necessary to invent a fabric desizing process with efficient water circulation to solve the above problems. Summary of the invention

Compared with the traditional process, while ensuring the desizing effect of the textile, it greatly saves water.

[0047] Second embodiment

[0048] like Figure 2 As shown, in order to further reflect the superiority of the fabric desizing process of the present invention with high-efficiency water circulation, the present embodiment provides a desizing device for high-efficiency water circulation fabric desizing, the device comprises a connecting part 2, a immersion section 3 is fixedly connected to the connecting part 2, a conveying part 4 is provided at both ends of the immersion section 3, a conveying part 5 is provided in the immersion section 3, the fabric 1 passes through a plurality of immersion sections 3 in sequence through the conveying part 4, a temperature sensor is provided in the immersion section 3, the temperature sensor is used to detect the temperature of the desizing liquid in the immersion section 3, the immersion section 3 is provided with a heating element, the temperature of the desizing liquid is detected in real time by arranging the temperature sensor in the immersion section 3, and the heating element is controlled to heat the desizing liquid according to the temperature change, so that the temperature of the desizing liquid in the immersion section 3 is always maintained within a preset range, thereby ensuring the desizing effect of the desizing liquid on the fabric 1, and at the same time, through the arrangement of a plurality of conveying parts 4, the fabric 1 can pass through a plurality of desizing devices in sequence for multiple desizing, thereby further improving the desizing effect of the device.

[0049] like Figure 3 As shown, the connecting portion 2 includes a plurality of first connecting rods 21, a plurality of second connecting rods 22 are arranged between two first connecting rods 21 on the same side, a plurality of load-bearing rods 23 are arranged between the second connecting rods 22 at the bottom on both sides, and a plurality of supporting rods 24 are fixedly connected to the bottom of the second connecting rod 22 at the bottom, and two adjacent desizing devices are connected through the same first connecting rod 21. By respectively arranging a plurality of second connecting rods 22 at both ends of a first connecting rod 21, the plurality of desizing devices are connected together, so that the fabric 1 can be desizing through the plurality of desizing devices in turn, thereby further improving the desizing effect of the fabric 1. At the same time, the arrangement of the plurality of desizing devices can avoid the problem of unsatisfactory desizing effect caused by excessive use of desizing liquid in the desizing device.

[0050] like Figure 4-Figure 5As shown, the impregnation section 3 includes a shell 31, which is fixedly mounted on the connecting portion 2. A plurality of desizing grooves 32 are provided in the middle of the inner cavity of the shell 31. Two adjacent desizing grooves 32 are separated by a same limiting member 33. A feed groove 34 and a discharge groove 35 are respectively provided at both ends of the inner cavity of the shell 31 distributed along the length direction. A plurality of observation windows 38 are fixedly connected to the shell 31, and the observation windows 38 correspond to the desizing grooves 32 one by one. By arranging a plurality of desizing grooves 32 in the shell 31 and separating the plurality of desizing grooves 32 by the limiting member 33, the fabric 1 entering the shell 31 can pass through the plurality of desizing grooves 32 in sequence to complete the desizing operation. At the same time, the plurality of observation windows 38 can be provided to intuitively observe the use of the desizing liquid in each desizing groove 32, so as to facilitate the subsequent replenishment and replacement of the desizing liquid, and avoid the problem that the desizing capacity cannot meet the actual use requirements due to excessive use of the desizing liquid.

[0051] The conveying part 4 includes a rotating seat, two rotating seats located on one side of the feed trough 34 are fixedly connected to the shell 31, two rotating seats located on one side of the discharge trough 35 are fixedly connected to the first connecting rod 21, and a rotating roller is provided between the two rotating seats located on the same side. The transmission part 5 includes a conveying roller 51, and a plurality of conveying rollers 51 are sequentially arranged above the feed trough 34, the stopper 33 and the discharge trough 35 and are rotatably connected to the shell 31. A padding roller 52 is provided at the lower part of each desizing trough 32. The fabric 1 is fed into the feed trough 34 through the conveying part 4, and sequentially passes through a plurality of conveying rollers 51 and the padding roller 52 to move toward the discharge trough 35, and the fabric 1 is transported by the conveying part 4. The sending-out padding section 3, when the fabric 1 needs to be desized, the rotating roller is driven by the motor to rotate, so that the fabric 1 moves into the feed trough 34, and the fabric 1 is moved to a desizing trough 32 by the conveying roller 51 arranged on the feed trough 34, and then the fabric 1 is continued to be driven to move into the second desizing trough 32 by the padding roller 52 arranged in the desizing trough 32 and is turned and moved into the second desizing trough 32 by the conveying roller 51 arranged on the limiter 33, and at the same time, the fabric 1 is driven by the padding roller 52 in the second desizing trough 32 to move to the conveying roller 51 located on the discharge trough 35, thereby completing the desizing operation of the fabric 1.

[0052] It should be noted that when the fabric 1 is conveyed multiple times by multiple conveying rollers 51 and padding rollers 52, a section of the fabric 1 in the desizing device is distributed in an "S" shape, so that the fabric 1 continuously contacts the desizing liquid in multiple desizing tanks 32 and completes the desizing operation.

[0053] A dust removal member 36 is provided in the feed trough 34. The dust removal member 36 is fixedly connected to the side wall of the desizing trough 32 near the feed trough 34, and one end of the dust removal member 36 penetrates the side wall and extends into the desizing trough 32. A water absorbent member 37 is also provided in the feed trough 34. The water absorbent member 37 is fixedly connected to the inner wall of the shell 31. By respectively arranging the dust removal member 36 and the water absorbent member 37 in the feed trough 34, when the fabric 1 moves from the feed trough 34 to the desizing trough 32, the impurities and desizing liquid adsorbed on the fabric 1 are first scraped and cleaned, thereby avoiding the problem of excessive contamination of the desizing liquid by impurities on the fabric 1.

[0054] Third embodiment

[0055] Based on the desizing equipment of the above embodiment, the operator found that the equipment has the problem of high water consumption. At the same time, when the fabric 1 is desizing, the surface of the shaft becomes rough due to aging or absorption of foreign matter by the transmission shaft during the contact between the fabric 1 and the transmission shaft, thereby scratching the fabric 1 and causing the surface of the fabric 1 to be damaged and unusable; and if the desizing liquid in the same desizing tank 32 is not replaced for a long time, its desizing ability for the fabric 1 will decrease, and if the desizing liquid is replaced frequently, it will cause unnecessary waste, which is not conducive to production. At the same time, the desizing liquid will separate after standing for a long time, and the device cannot effectively clean the impurities suspended in the desizing liquid, thereby affecting the desizing effect.

[0056] Therefore, in order to solve the above technical problem, the device is improved according to the method described in this embodiment.

[0057] like Figure 6-Figure 10 As shown, the conveying part 5 also includes a collecting roller 53, which is arranged above the desizing tank 32, and one end of the collecting roller 53 passes through the shell 31 and is connected to the rotating motor, and the other end of the collecting roller 53 passes through the shell 31 and is connected to a conveying pipe 54, and the other end of the conveying pipe 54 is communicated with the immersion roller 52 in another desizing tank 32, and the conveying pipe 54 is provided with a pumping part 56. The collecting roller 53 and the immersion roller 52 have the same structure, and the collecting roller 53 is provided with a plurality of water outlet holes 55 in an annular array along the side of the shaft. The collecting roller 53 is a hollow structure, and the collecting roller 53 The inner cavity is connected with the conveying pipe 54. A collecting roller 53 is arranged above the desizing tank 32, and one end of the collecting roller 53 is connected with the conveying pipe 54. Meanwhile, the other end of the conveying pipe 54 is connected with the padding roller 52 in another desizing tank 32. When the collecting roller 53 is driven by the rotating motor to rotate, the pumping unit 56 is controlled to work. Under the action of suction, the collecting roller 53 sucks the desizing liquid in one desizing tank 32 into the conveying pipe 54, and transports it to another desizing tank 32 through the conveying pipe 54, thereby realizing the recycling of the desizing liquid.

[0058] It should be noted that when desizing the fabric 1, multiple desizing devices need to be set up to ensure the desizing effect. Figure 6As shown, two desizing devices are provided as an example. When the desizing liquid needs to be recycled, the desizing liquid that contacts the fabric 1 later is transported to the desizing tank 32 that contacts the fabric 1 first through the pumping unit 56. Since the desizing liquid that contacts the fabric 1 later has a relatively pure component for desizing compared to the desizing liquid that contacts the fabric 1 first, the purity of the desizing liquid in the desizing tank 32 that contacts the fabric 1 first can be improved by transporting the desizing liquid that contacts the fabric 1 later to the desizing tank 32 that contacts the fabric 1 first. At the same time, the prepared desizing liquid is sent to the desizing tank 32 that contacts the fabric 1 later through the transmission pipe 54, and the desizing liquid that contacts the fabric 1 first is sent to the purification and recovery equipment through the transmission pipe 54 for purification and secondary use, thereby realizing efficient recycling of the desizing liquid and avoiding the problem of waste of the desizing liquid to a great extent. At the same time, by continuously replacing the desizing liquid, the desizing effect of the desizing liquid in each desizing tank 32 on the fabric 1 is further improved, avoiding the problem of decreased desizing ability due to excessive use of the desizing liquid.

[0059] A scraping portion 6 is provided on the limiting member 33, and the scraping portion 6 includes a base 61, which is fixedly connected to the top of the limiting member 33, and two telescopic members 62 are symmetrically provided at both ends of the base 61 distributed in the width direction, and each telescopic member 62 is fixedly connected to a connecting member 63 at one end away from the base 61, and an elastic member 64 is fixedly connected between the two connecting members 63, the elastic member 64 is arranged in the upper half area of ​​the two connecting members 63, and the telescopic member 62 is arranged in the lower half area of ​​the connecting members 63, and the elastic member 64 includes an elastic layer and a cleaning layer, the elastic layer is located below the cleaning layer, and the cleaning layer includes a water-absorbing sponge.

[0060] First, when it is necessary to move the fabric 1 from the feed trough 34 to the first desizing trough 32, the conveying roller 51 arranged above the feed trough 34 is controlled to drive the fabric 1 to move into the first desizing trough 32. When it is necessary to move the fabric 1 from the first desizing trough 32 to the second desizing trough 32, the padding roller 52 located in the first desizing trough 32 and the conveying roller 51 arranged on the limiter 33 are controlled to drive the fabric 1 from the first desizing trough 32 to the second desizing trough 32. During this process, the collecting roller 53 located in the second desizing trough 32 conveys the desizing liquid in the second collecting roller 53 to the padding roller 52 in the first desizing trough 32 through the work of the pumping part 56, and the desizing liquid is discharged through the multiple water outlets 55 arranged on the padding roller 52. At this time, since the padding roller 52 keeps rotating, the water flow sprayed by the padding roller 52 contacts the fabric 1 instead of the transmission shaft to drive the fabric 1 to move, thereby avoiding the problem that the surface of the fabric 1 is scratched during the movement and cannot be used subsequently.

[0061] Secondly, the water sprayed from the water outlet 55 contacts the surface of the fabric 1 through the rotation of the padding roller 52, and washes the surface of the fabric 1. On the one hand, the desizing liquid is fully immersed in the fabric 1 to improve the desizing effect on the fabric 1. On the other hand, new desizing liquid is discharged to the bottom of the desizing tank 32 and the desizing liquid is mixed for the second time under the rotation of the padding roller 52, thereby avoiding the problem of precipitation and stratification of the desizing liquid after being placed in the desizing tank 32 for a long time, thereby further improving the desizing effect of the device on the fabric 1.

[0062] Next, when it is necessary to clean the impurities adsorbed on the upper and lower surfaces of the fabric 1 in the desizing tank 32, the telescopic member 62 is controlled to extend in a direction away from the base 61, so that the elastic member 64 arranged on the telescopic member 62 is driven by the connecting member 63 to be equipped from a bent state to a horizontal state. At this time, the side of the elastic member 64 will contact the lower surface of the fabric 1, and the impurities adsorbed on the lower surface of the fabric 1 will be scraped off. At the same time, the amount of water discharged outward by the immersion roller 52 is changed by controlling the suction force of the pumping part 56, so that the desizing liquid discharged from the water outlet 55 rinses the upper surface of the fabric 1, separates the impurities adsorbed on the upper surface of the fabric 1 from the fabric 1, and moves the impurities upward under the drive of the water flow, and collects and processes the impurities through the collecting roller 53, thereby avoiding the problem that too many impurities are adsorbed on the surface of the fabric 1, resulting in insufficient contact between the fabric 1 and the desizing liquid.

[0063] Finally, when it is necessary to clean the surface of the collecting roller 53 arranged above the limiter 33, the water pressure of the desizing liquid discharged outward by the padding roller 52 is controlled to become smaller, thereby reducing the tension of the fabric 1, so that the fabric 1 and the collecting roller 53 arranged on the limiter 33 slide against each other. At this time, the collecting roller 53 here cannot drive the fabric 1 to continue to move. At the same time, the telescopic member 62 is controlled to move in the direction close to the base 61, so that the elastic member 64 is changed from a horizontal state to an upward bending state, so as to contact with the bottom of the collecting roller 53 here, and the impurities adsorbed on the collecting roller 53 are scraped off, so as to avoid the impurities adsorbed on the collecting roller 53 contacting with the fabric 1 under the extrusion force, resulting in the surface of the fabric 1 being scratched. At the same time, by controlling the size of the water flow sprayed from the padding roller 52, the tension of the fabric 1 can be adjusted according to the thermal expansion and contraction of different fabrics 1, so as to avoid the problem of excessive stretching of the fabric 1 during the desizing process, resulting in the breakage of the fabric 1.

[0064] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
