Description

Technical Field

[0001] This invention belongs to the technical field of wool processing equipment, and in particular relates to an array-type high-efficiency device and method for stripping wool scales. Background Technology

[0002] Wool fiber, as a protein fiber, is widely used in the apparel market due to its natural warmth-retaining properties. However, in actual production and use, it has been found that the dense scaly layer structure on the surface of wool fibers, while resisting external mechanical and chemical erosion, also brings problems such as felting, static electricity, itching, and difficulty in dyeing, greatly limiting the application potential of wool products. To address these issues, the commonly used method is to peel and destroy the wool scales, reducing the thickness of the scale layer to achieve a smoother overall fiber surface and improved hydrophilicity, thereby alleviating problems such as felting and itching.

[0003] Common descaling methods include chlorination or alkaline treatment. For example, the invention patent application CN201710812156.3, "A method and equipment for treating wool scales," effectively destroys wool scales by sequentially treating the parallel wool layers of the wool slivers with chlorination, dechlorination, dephosphorization, and resin impregnation. However, such methods increase the process steps in normal wool spinning, and the use of large amounts of chlorides weakens the controllability of damage to the main wool fibers and increases environmental pressure.

[0004] In addition, the invention patent with application number CN201610163206.5 uses a micro-water system to modify the scales on the surface of wool. It uses microcapsules formed by ethoxylated alkyl sulfate sodium, n-octanol and decamethylcyclopentasiloxane to encapsulate sodium hydroxide, which reduces the amount of sodium hydroxide used and its damage to wool fibers. However, the impregnation method still has quantitative requirements on the amount of treatment solution used.

[0005] Besides chemical methods, physical methods such as plasma and ultrasound can also be used to damage wool scales. For example, plasma technology can generate high-energy particles to bombard the fiber surface, thereby etching and destroying the scales. However, this process often requires the injection of gases such as helium or nitrogen to achieve the desired effect, which places high demands on the environment and can negatively affect the basic mechanical properties of wool. The patent application number CN202010825079.7, however, uses ultrasonic vibration and microwave action to damage the scale tips of wool fibers loaded with inorganic particles, thereby reducing the directional friction effect of the fiber and improving its shrinkage resistance and dyeability without affecting its basic mechanical properties.

[0006] In summary, while physical methods in the prior art can effectively reduce damage to the wool fiber matrix compared to chemical methods and avoid the use of strong oxidizing agents, they generally suffer from higher equipment costs or lower processing efficiency. Furthermore, purely chemical methods struggle to control the degree of damage to the wool fiber matrix. Therefore, it remains necessary to provide a device or method for peeling wool scales that combines physical and chemical methods while avoiding severe damage to the wool fiber matrix caused by chemical reagents. Summary of the Invention

[0007] The purpose of this invention is to provide an array-type high-efficiency device and method for stripping wool scales, combining physical and chemical methods to solve the technical problems mentioned in the background art.

[0008] The technical solution adopted by this invention to solve its technical problem is: to provide an array-type high-efficiency wool scale removal device, including a wool conveying device, a negative pressure suction device, and an array stripping device. The wool conveying device includes a metal conveying mesh curtain arranged in a ring. Several mesh curtain winding rollers and the negative pressure suction device are provided on the inner side of the metal conveying mesh curtain. The mesh curtain winding rollers support and drive the metal conveying mesh curtain in a cyclical transmission. One side of the metal conveying mesh curtain is the working surface. The suction port of the negative pressure suction device is arranged facing the working surface. The wool combing web is adsorbed onto the outer surface of the metal conveying mesh curtain by the negative pressure suction device and moves with the wool. This is a transmission mesh curtain drive transportation system. The array stripping device includes a high-voltage power supply, a liquid supply device, and several sets of nozzle arrays. Each set of nozzle arrays is connected in parallel with the high-voltage power supply. Each set of nozzle arrays includes an electric field enhancement module and an array ionization module. The electric field enhancement module includes a connecting plate with an internal solution channel and an electric field enhancement cone. The array ionization module is located on the connecting plate. The electric field enhancement cone is located on both sides of the array ionization module. The array ionization module consists of several single-needle nozzles arranged in an array facing the working surface. The single-needle nozzles are connected to the solution output pipe of the liquid supply device through the solution channel located in the connecting plate.

[0009] Preferably, the metal conveyor screen is supported by four rubber screen rollers located on its inner side, forming a hollow trapezoidal structure. The upper and lower bases of the trapezoidal structure are parallel to the horizontal plane, with the lower base serving as the working surface. The array peeling device is located below the working surface, and the single-needle nozzle is arranged vertically upwards towards the working surface.

[0010] Preferably, the metal transmission mesh curtain has a plain weave structure, wherein the warp direction of the plain weave is made of polyvinyl chloride yarn and the weft direction is made of stainless steel yarn.

[0011] Preferably, the negative pressure suction device is located inside the ring of the metal conveyor screen, with the suction port of the negative pressure suction device facing the working surface. The applied negative pressure range is -1000 to -300 Pa, used to adsorb the wool combing web and make it adhere tightly to the side of the working surface of the metal conveyor screen away from the negative pressure suction device.

[0012] Preferably, the liquid supply device includes a scale treatment liquid storage tank, which is connected to a peristaltic pump via a solution input pipe. The peristaltic pump is connected to the solution channel via several solution output pipes, and the other end of the solution channel is connected to each of the single-needle nozzles.

[0013] Preferably, the peristaltic pump has a rotational speed range of 10~300 rpm, the solution inlet pipe is made of polyvinyl chloride with a diameter of 10~15 mm, and the solution outlet pipe is made of polyvinyl chloride with a diameter of 5~8 mm.

[0014] Preferably, the single-needle nozzle is made of stainless steel, has a cross-sectional diameter of 0.1-1mm, and is arranged at a linear density of 10-25 nozzles / cm along the length of the connecting plate.

[0015] To address the aforementioned technical problems, the present invention also provides a method for efficiently removing wool scales in an array, using the aforementioned apparatus for efficiently removing wool scales in an array, comprising the following steps:

[0016] Step 1: Dissolve the scale treatment substance in water and stir to obtain a scale treatment solution with a solute concentration of 2-5 wt%.

[0017] Step 2: Loosen and comb the wool fibers to obtain a wool combing web. Place both ends of the wool combing web on the conveyor screen and start the negative pressure suction device to draw air, so that the wool combing web is in close contact with the working surface of the metal conveyor screen to start transportation.

[0018] Step 3: The scale treatment solution prepared in Step 1 is transferred from the solution input pipe to each solution output pipe using the suction action of a peristaltic pump. Finally, it is transported to the surface of the single needle nozzle through each array of dispensing pipes. Under the action of a high-voltage power supply, it undergoes array ionization, electro-atomizing into micro-nano-sized droplets. These droplets are then sprayed towards the fiber web under the action of the electric field force. At the same time, under the action of the electric field enhancement module, the spatial field strength of the fiber web is enhanced, and the fiber polarization movement forms pore channels arranged along the electric field direction. This allows the negatively charged micro-nano-sized droplets to be sprayed vertically into the pore channels along the thickness direction of the wool combing fiber web and quickly combine with the positively charged wool fiber surface. Meanwhile, the warping deformation caused by the charge accumulation at the scale tip and the enhanced electrostatic repulsion accelerates the penetration of the scale treatment substance, realizing the online and efficient composite of the scale treatment substance and wool fiber.

[0019] Step 4: The resulting composite wool combed web is gathered through a funnel-shaped opening, and the resulting wool tops are left to stand to ensure that the scale treatment solution fully reacts with the wool scales.

[0020] In step 1, the scale treatment solution is a dichloroisocyanurate solution, a sodium bisulfite solution, or a sodium hypochlorite solution.

[0021] Preferably, in step 3, the process parameters for array ionization are: the high-voltage power supply operating range is -50~-10kV, the vertical distance between the tip of the single-needle nozzle arranged in the array and the metal transmission mesh curtain is 3~10cm, the ambient humidity is 35~65%, and the ambient temperature is 20~27℃; the resting conditions for the wool strips in step 3 are: the ambient humidity is 50~70%, the ambient temperature is 25~30℃, and the resting time is 0.5~2h.

[0022] The beneficial effects are as follows: Based on the original wool combing web production device, the present invention extends the web conveying path, adds an array stripping device, and uses an electric field enhancement module and an array ionization module in conjunction to achieve online and efficient stripping of wool scales without affecting the wool combing process.

[0023] The synergistic operation of the above-mentioned devices enables the array bonding of micro- and nano-scale scale treatment liquid with wool fibers. By adjusting the electric field strength and array distribution, the penetration and reaction of the scale treatment liquid can be controlled, providing technical support for the controllable production of scale removal. This solves the technical problems of conventional scale removal technology, such as long process flow, high reagent consumption, and significant damage to fiber strength, and ensures efficient and controllable removal of wool scales.

[0024] This invention combines physical and chemical methods to remove the scales from wool fibers. First, an external electric field is applied through an electric field enhancement module to initially damage the wool scales, causing them to warp due to electrostatic repulsion. Then, a scale treatment liquid further removes the scales in a controlled manner based on this electrostatic repulsion. Specifically, under the drive of an electric field, a positively charged atomized scale treatment liquid adheres to the surface of the wool fibers and, under the influence of electrostatic force, penetrates into the interior, achieving a controlled distribution of the liquid within the wool fiber scale layer and effective control over the degree of wool scale removal.

[0033] like Figure 1In one specific embodiment shown, the present invention provides an array-type high-efficiency wool scale removal device, including a wool conveying device, a negative pressure suction device 6, and an array stripping device. The wool conveying device includes a metal conveying mesh curtain 5 arranged in a ring. A plurality of mesh curtain winding rollers 4 and the negative pressure suction device 6 are arranged inside the metal conveying mesh curtain 5.

Source 1, liquid supply device and several sets of nozzle arrays, each set of nozzle arrays is connected in parallel with the high voltage power supply 1, each set of nozzle arrays includes an electric field enhancement module 2 and an array ionization module 3 welded together, the electric field enhancement module 2 has an "H" shaped cross-section and includes two vertically arranged support legs 201, the upper part of the support legs 201 has a tip with a right-angled triangular cross-section, the support legs 201 are connected by a horizontally arranged connecting plate 202, the upper surface of the connecting plate 202 is provided with the array ionization module 3, the array ionization module 3 is a number of single needle nozzles 301 arranged in an array, the single needle nozzles 301 are connected to the solution output pipe 9 of the liquid supply device through a solution channel provided in the connecting plate 202.

[0034] In this embodiment, the metal transmission mesh curtain 5 is supported by four rubber mesh curtain rollers 4 located at its four inner corners, forming a hollow trapezoidal structure. The upper and lower bases of the trapezoidal structure are parallel to the horizontal plane, with the lower base serving as the working surface and longer than the upper base. The cavity inside the trapezoidal structure accommodates the negative pressure suction device 6. The metal transmission mesh curtain 5 is grounded to ensure that the negatively charged scale treatment atomized liquid and the positively charged wool combing fiber web after friction are not affected.

[0035] In this embodiment, the metal conveyor mesh curtain 5 has a plain weave structure with a width of 80cm. The warp direction of the plain weave is made of polyvinyl chloride yarn, and the weft direction is made of stainless steel yarn. The mesh curtain winding roller 4 is driven by a rotary motor to rotate and drive the metal conveyor mesh curtain 5 to rotate cyclically. The conveying speed of the metal conveyor mesh curtain 5 is 15m / min.

[0036] In this embodiment, the negative pressure suction device is located inside the ring of the metal conveyor mesh curtain. The negative pressure suction device includes a vacuum pump connected to a suction pipe. The end of the suction pipe is an open suction port 601, which is arranged facing the working surface. The applied negative pressure range is -1000 to -300 Pa, used to adsorb wool combing fibers and make them adhere tightly to the side of the working surface of the metal conveyor mesh curtain opposite to the negative pressure suction device.

[0037] The liquid supply device includes a scale treatment liquid storage tank, which is connected to a peristaltic pump 7 via a solution input pipe 8. The peristaltic pump 7 is connected to the nozzle array via several solution output pipes 9.

[0038] The peristaltic pump 7 has a rotational speed range of 100 rpm, the solution inlet pipe 8 is made of polyvinyl chloride and has a diameter of 10 mm, and the solution outlet pipe 9 is made of polyvinyl chloride and has a diameter of 6 mm.

[0039] like Figure 2 In one specific embodiment shown, the electric field enhancement module 2 is a horizontally arranged straight copper prism with an "H"-shaped cross-section. The concave portion formed by the two vertical and one horizontal sections at the top of the "H" shape is an isosceles trapezoid. The two vertical sections at the top of the "H" shape are the electric field enhancement cone 203. The apex of the electric field enhancement cone 203 is parallel to the horizontal plane. The circumscribed rectangle of the straight copper prism has a length of 2 cm and a height of 3 cm. The upper base of the isosceles trapezoid coincides with the upper long side of the rectangle, while the lower base is inside the rectangle. The angle between the two legs of the isosceles trapezoid and the two wide sides of the rectangle is 10°, and the height is 1.5 cm. The "H"-shaped crossbar is a connecting plate 202, which has a hollow structure inside and contains a solution delivery channel with a rectangular cross-section. The rectangular cross-section is 0.8 cm long and 0.5 cm high. The lower surface of the solution delivery channel is 5 mm away from the lower surface of the connecting plate 202, and it forms a hollow structure by penetrating along the length (horizontal) of the prism line. The hollow structure is connected to the solution output pipe 9 for solution loading and transportation. Several dispensing pipes with a diameter of 0.4 mm are connected to the upper surface of the solution output pipe 9.

[0040] The nozzle array is composed of several parallel array ionization modules 3. The array ionization module 3 is 70cm long, and the single needle nozzle 301 on it is made of stainless steel with a cross-sectional diameter of 0.2mm. The linear density of the nozzles arranged along the length of the connecting plate 202 is 15 nozzles / cm. The bottom outer surface of the nozzle is welded to the prism bar and connected to the liquid distribution pipe. The liquid distribution pipe transports the solution provided by the liquid supply device to the surface of the array single needle nozzle 301. Under the action of external high pressure, the array ionization effect is performed, and the resulting electro-atomized scale treatment liquid is sprayed onto the surface of the wool combing web.

[0041] To address the aforementioned technical problems, the present invention also provides a method for efficiently removing wool scales in an array, using the aforementioned apparatus for efficiently removing wool scales in an array, comprising the following steps:

[0042] Step 1: Dissolve the scale treatment substance in water and stir to obtain a scale treatment solution with a solute concentration of 3 wt%.

[0043] Step 2: Loosen and comb the wool fibers to obtain a wool combed web. Place both ends of the wool combed web on the conveyor screen and start the negative pressure suction device 6 to suck air, so that the wool combed web is tightly attached to the metal conveyor screen 5 to start transportation.

[0044] Step 3: The scale treatment solution prepared in Step 1 is transferred from the solution input pipe 8 to each solution output pipe 9 by the peristaltic pump 7. Finally, it is transported to the surface of the single needle nozzle 301 through each array of dispensing pipes. Under the action of the high voltage power supply 1, it undergoes array ionization and electro-atomization into micro-nano-sized droplets. Under the action of the electric field force, the droplets are sprayed towards the fiber web. At the same time, under the action of the electric field enhancement module 2, the field strength of the space where the fiber web is located is enhanced. The fiber polarization movement forms pore channels arranged along the electric field direction, so that the negatively charged micro-nano-sized droplets are sprayed vertically into the pore channels along the thickness direction of the wool combing fiber web and quickly combine with the positively charged wool fiber surface. At the same time, the warping deformation caused by the charge accumulation at the scale tip and the enhanced electrostatic repulsion accelerates the penetration of the scale treatment substance, realizing the online efficient composite of the scale treatment substance and wool fiber.

[0045] Step 4: The resulting composite wool combed web is gathered through a funnel-shaped opening, and the resulting wool tops are left to stand to ensure that the scale treatment solution fully reacts with the wool scales.

[0046] The scale treatment solution in step 1 includes dichloroisocyanurate, sodium bisulfite, or sodium hypochlorite.

[0047] In one specific embodiment, the process parameters for the array ionization effect in step 3 are as follows: the high-voltage power supply 1 operates within a range of -50kV, the vertical distance between the tip of the single-needle nozzle 301 arranged in the array and the metal transmission mesh curtain 5 is 5cm, the ambient humidity is 35%, and the ambient temperature is 25℃; the conditions for the strand resting in step 4 are as follows: the ambient humidity is 50%, the ambient temperature is 25℃, and the resting time is 1h.

[0048] The electron micrograph of scaled wool produced by the array-based high-efficiency wool scale removal method provided in this embodiment is shown in the figure below. Figure 4 As shown.

[0049] In addition, a commonly used chemical chlorination process for wool treatment in the prior art is as follows: Take 5 mL of NaClO solution with an effective chlorine content of 12%, dilute it with deionized water to 50 mL, adjust the pH to 2, add wool fibers at a bath ratio of 1:20, react at room temperature for 20 minutes, then remove the wool fibers, wash and squeeze dry several times, treat with 1% sodium bisulfite solution for 15 minutes at a bath ratio of 1:20, finally wash with deionized water several times, and dry in an oven at 60℃. The electron micrograph of the scaled wool produced using this chemical method is shown below. Figure 5 As shown.

[0050] For example Figure 3 Based on the electron microscope image of unscaled wool shown below, it can be seen that compared to... Figure 5 The wool shown is descaled using only chemical methods of chlorination, while the wool obtained using the apparatus and method of this invention is as follows. Figure 4 The scaled wool shown is cleanly scaled while suffering minimal chemical damage.

[0051] Based on the original wool combing web production device, this invention extends the web conveying path and adds an array stripping device. It works in conjunction with an electric field enhancement module 2 and an array ionization module 3. On the one hand, the electric field enhancement module 2 optimizes the array electric field distribution in the space where the web is located, causing the wool fibers to polarize and align along the electric field direction to form pore channels. On the other hand, the array ionization module 3 promotes the array ionization and atomization spraying of the scale treatment liquid. The negatively charged atomized droplets are driven by electrostatic force and sprayed through the pore channels onto the surface of the wool fibers that are positively charged due to friction, achieving efficient online combination of the two. Simultaneously, driven by the electric field, the wool scales warp due to electrostatic repulsion, causing the oxidized negative ions in the atomized scale treatment solution to tend to migrate directionally to the anode, i.e., the metal mesh end. This accelerates the penetration and reaction of the micro-nano scale treatment solution in the wool scale layer. By controlling the array electric field, the array spraying of the atomized scale treatment solution can be achieved. Under the premise of using as little scale treatment solution as possible, its controllable distribution in the wool fiber scale layer can be achieved, providing a strong guarantee for the effective control of the degree of wool descaling reaction and the maintenance of the basic strength of wool fibers.

[0052] The working principle of this device is as follows: During the carding process, wool fibers become positively charged after rubbing against other fibers or carding components. As they travel along the conveyor mesh to the array stripping device, the electric field enhancement module 2 polarizes the fibers in the web and causes them to move under force, tending to align along the direction of the electric field and forming pore channels within the web. Simultaneously, the liquid supply device delivers the flake treatment liquid to the surface of the single-needle nozzle 301 of the array ionization module 3. Under the action of an external negative high voltage, the solution undergoes array ionization, forming a negatively charged electrospray that is sprayed towards the web and enters the formed pore channels. Through the attraction of positive and negative charges, the array of flake treatment liquid droplets adheres to the surface of the wool fibers. Simultaneously, driven by the electric field, the wool scales warp due to electrostatic repulsion, and the oxidized negative ions in the atomized scale treatment liquid tend to migrate directionally to the anode, i.e. the metal mesh end, accelerating the penetration and reaction of the micro-nano scale treatment liquid in the wool scale layer. By controlling the array electric field, the array spraying of the atomized scale treatment liquid can be realized, achieving its controllable distribution and reaction in the wool fiber scale layer.
