Description

Technical Field

[0001] This invention relates to the field of wool fulling technology, and in particular to a special fulling and washing process for granular wool. Background Technology

[0002] Wool pellets are a type of woolen fabric spun from wool yarn with a granular surface. During processing, fulling is typically required. The purpose of fulling is to shrink the wool fibers tightly, causing them to intertwine and form felt, resulting in a fine, short pile layer on the fabric surface and a unique granular appearance. After fulling, wool pellets become denser, fluffier, and more elastic, while also increasing their warmth, pilling resistance, and durability.

[0003] Currently, most wool fulling equipment used is fulling machines, such as the wool sweater fulling machine disclosed in Chinese invention patent CN119663577A. While this machine can increase the speed and dehydration of wool sweater fulling when fulling ordinary wool, shortening the overall fulling process and improving work efficiency, and ensuring the wool sweater is fully in contact with the fulling solution, guaranteeing uniformity and effectiveness, it presents the following problems when fulling tufted wool: First, tufted wool and ordinary wool differ in fiber characteristics and fabric structure. Tufted wool, after special treatment, has finer and shorter fibers. Under the same felting process, the felting degree and speed of wool may differ from those of ordinary wool. This can result in either insufficient felting, failing to form the desired granular appearance and dense texture, or excessive felting, leading to felting, a stiff hand feel, and other problems that affect product quality. Furthermore, due to the different felting characteristics of the two types of wool, it is difficult to find the optimal process parameters suitable for both using the same set of equipment. This requires operators to adjust the parameters and the mechanical structure, and then adjust them back later, which is quite cumbersome and requires optimization and improvement of existing equipment. Therefore, this application provides a special felting and washing process for wool pellets to meet the needs. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a special fulling and washing process for granular wool, which solves the problem that existing fulling machines require frequent adjustments to parameters and mechanical structures when fulling granular wool, making them cumbersome and inconvenient to use.

The separator rod is welded and installed on the outer side inside the inner lining ring, and the arc-shaped groove is symmetrically opened on the inner side of the front end of the inner cylinder ring.

[0012] Preferably, the balancing module and the lateral clamping module are combined into an integrated installation structure. Two sets of felting modules are symmetrically distributed on the left and right. The transmission end of the rotating motor extends into the interior of the integrated structure formed by the balancing module and the lateral clamping module. Two transmission motors are symmetrically distributed on the left and right. The transmission motors and the rotating module transmit power through a transmission chain.

[0016] The separator bars are welded together with the inner cylinder ring, permeable plate, and inner lining ring to form a cylindrical structure. Then, the assembly strips are inserted into the arc-shaped grooves to complete the installation. Since the assembly strips are an assembly structure and have striped protrusions on the inner side, they can better allow the wool particles to rub against them during felting. When it is necessary to adjust the internal friction parts later, they can be replaced as needed, and it is also quicker to replace them when they are worn out. Attached Figure Description

[0026] like Figures 1 to 9 As shown, embodiments of the present invention provide a special felting and washing process for granular wool, including the following steps: S1. Soaking: First, soak the wool garment in water. You can use cashmere detergent or other suitable detergents. S2. Fulling: The soaked wool pellet garment is placed into the fulling liquid of the fulling equipment for fulling treatment; S3. After the fulling is completed, the wool pellet garments need to be washed to remove any residual fulling solution and other impurities. S4. Dehydration: After washing, dehydrate the clothes to remove excess water. S5. Drying: Finally, dry the dehydrated wool garments. The felting equipment includes a base 1, a balancing module 2 on the inner side of the upper end of the base 1, transverse clamping modules 3 on the left and right sides of the outer end of the balancing module 2, a felting module 4 sleeved on the inner side of the transverse clamping module 3, a protruding plate 5 on the upper part of the front end of the base 1, a rotating motor 6 on the upper end of the protruding plate 5, a transmission motor 7 on the left and right sides inside the base 1, a rotating module 8 on the upper part of the transmission motor 7, an inner cylinder module 9 in the middle of the inner side of the felting module 4, and an assembly strip 10 distributed in a ring on the outer side inside the inner cylinder module 9. A support plate 11 is provided at the lower end of the rotating module 8.

[0027] The balancing module 2 and the transverse clamping module 3 are combined into an integrated installation structure. Meanwhile, since the front and rear ends of the balancing module 2 penetrate the interior of the upper structure of the base 1, and the transmission end of the rotating motor 6 is connected to the rear end of the balancing module 2, two sets of felting modules 4 are symmetrically distributed on the left and right, and are clamped and fixed on the front and rear sides by the transverse clamping module 3. There are two transmission motors 7 symmetrically distributed on the left and right. The transmission motors 7 and the rotating module 8 transmit power through a transmission chain. The assembly strip 10 is embedded in the inner cylinder module 9 on the outer side in a ring. The support plate 11, the rotating module 8 and the base 1 are reinforced with bolts.

[0028] The rotating motor 6 can rotate and drive the integrated structure formed by the balance module 2 and the horizontal clamping module 3 to move left and right, forming a swing structure. At the same time, two sets of fulling modules 4 are installed at the left and right ends of the swing structure. According to production needs, the two sets of fulling modules 4 and the transmission motor 7 and rotating module 8 installed symmetrically on the left and right below can be preset to form two working modes. The left side is used for ordinary wool fulling, and the right side is used for granular wool fulling. Compared with the traditional single-tube design, it does not require frequent changes to internal parameters and mechanical structure. The overall operation is more convenient, improving the applicability of the device for fulling wool products.

[0029] like Figures 1 to 4 As shown, in this embodiment, the base 1 includes a base body 101, a U-shaped frame 102, mounting holes 103, a reinforcing groove 104, and a concave groove 105. The U-shaped frame 102 is provided in the middle of the upper end of the base body 101. Mounting holes 103 are provided on the left and right sides of the upper end of the U-shaped frame 102. Reinforcing grooves 104 are provided on the left and right sides of the outer end of the base body 101. A concave groove 105 is provided on the front side of the upper end of the base body 101.

[0030] The base 101 and the U-shaped frame 102 are integrated into one structure. The mounting holes 103 are symmetrically distributed, and rectangular screw holes are provided below the mounting holes 103. A ground pin hole is provided on the lower inner side of the reinforcing groove 104. There are two concave grooves 105 symmetrically distributed on the left and right.

[0031] The U-shaped frame 102 allows the integrated structure formed by the balancing module 2 and the transverse clamping module 3 to be installed on the inner side. This, combined with the rotating motor 6, forms a bidirectional swing structure. When a particular side of the felting module 4 needs to work, the rotating motor 6 rotates in that direction, lowering that side of the felting module 4 to fit snugly against the rotating module 8 below. Simultaneously, the concave groove 105 allows the transmission end of the drive motor 7 to extend out. A sprocket is then installed on the transmission end of the drive motor 7. This, along with the central guide rod 803 installed in the middle of the upper part of the rotating module 8, uses a chain to transmit power between the extended end of the central guide rod 803 and the sprocket installed on the transmission end of the drive motor 7. This drives the meshing guide wheel 806 in the rotating module 8 to rotate, thereby rotating the fitted felting module 4 and initiating the felting process.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the balancing module 2 includes a middle rod 201, a wear-resistant bearing 202, a central shaft 203, and a pin 204. The wear-resistant bearing 202 is provided on the front and rear sides of the outer end of the middle rod 201, the central shaft 203 is provided on the inner side of the middle rod 201, and the pin 204 is provided on the front and rear sides of the upper end of the middle rod 201. The transverse clamping module 3 includes a crossbar 301, an arc-shaped block 302, and a collar 303. The arc-shaped block 302 is provided on the left and right sides of the outer end of the crossbar 301, and the collar 303 is provided on the outer end of the arc-shaped block 302.

[0033] The middle rod 201 and the cross rod 301 are installed in an I-shape. The cross rod 301 passes through the interior of the front and rear ends of the middle rod 201. The connecting structures extending from both sides of the cross rod 301 are of equal length. Then, the central shaft 203 passes through the middle of the combined structure of the middle rod 201 and the cross rod 301. Subsequently, the pin 204 is used at the top to pass through the interior of the middle rod 201, the cross rod 301 and the central shaft 203 in sequence, and extends to the outside at the bottom to be fixed with a nut, so as to ensure the stability of the installation structure between the middle rod 201, the cross rod 301 and the central shaft 203. Then, the anti-wear bearing 202 is sleeved and installed at the front and rear ends of the central shaft 203. The arc block 302 and the cross rod 301 are installed in an integrated structure. The arc block 302 and the collar 303 are reinforced with bolts.

[0034] The wear-resistant bearing 202 is installed on the inner side of the contact end between the middle rod 201 and the U-shaped frame 102. Then, the I-shaped structure formed by the combination of the middle rod 201 and the crossbar 301 is installed on the inner side of the U-shaped frame 102. After maintaining a horizontal angle with the mounting hole 103, the central shaft 203 is inserted. The pin 204 is used to pass through the interior of the middle rod 201, the crossbar 301 and the central shaft 203 in sequence, and extends to the lower outer side to be fixed with a nut, so that it forms a swing structure that can be raised and lowered left and right on the inner side of the U-shaped frame 102.

[0035] like Figure 7 As shown, in this embodiment, the felting module 4 includes an outer cylinder 401, a sealing block 402, a cylinder bushing 403, an inner sealing ring 404, a sealing groove 405, an outer toothed ring 406, a guide ring 407, and a sealing door 408. The outer cylinder 401 has sealing blocks 402 on its front and rear sides. The outer end of the sealing block 402 is fitted with a cylinder bushing 403. The inner sealing ring 404 is provided on the front and rear sides inside the outer cylinder 401. A sealing groove 405 is opened on the inner side of the front end of the inner sealing ring 404. The outer toothed ring 406 is provided in the middle of the outer end of the outer cylinder 401. The guide ring 407 is provided on the front and rear sides of the outer end of the outer cylinder 401. The sealing door 408 is provided at the front end of the sealing block 402.

[0036] The outer cylinder 401, outer toothed ring 406, and guide ring 407 are integrated into a single unit. Two sets of sealing blocks 402, cylinder bushing 403, inner sealing ring 404, and sealing groove 405 are symmetrically distributed front and rear. The sealing blocks 402 and sealing gate 408 installed on the front side are connected by a slot-type installation. A conveying pipe is located in the middle of the inner side of the sealing block 402 installed on the rear side. A sealing gasket is installed between the sealing groove 405 at the front end of the inner sealing ring 404 and the contact end of the sealing block 402. The outer toothed ring... The tooth groove spacing of 406 is matched with the tooth groove spacing of the meshing guide wheel 806, and the two can mesh and transmit power. There are two guide rings 407 symmetrically distributed, and the distance between the two guide rings 407 matches the distance between the embedded guide wheels 807 installed on the front and rear sides of the outer end of the side guide rod 804. The outer end of the guide ring 407 protrudes and matches the size of the inner groove of the embedded guide wheel 807. The sealing door 408 is a known technology, so it will not be described in detail in this article.

[0037] The outer toothed ring 406 and guide ring 407 form a power transmission structure at the outer end of the outer cylinder 401. Then, in conjunction with the middle guide rod 803 and side guide rod 804 in the lower rotating module 8, a roller-type rotating structure is formed. Together with the inner cylinder module 9, a horizontal fulling cavity is maintained. During the subsequent fulling of the wool pellets, the mixing of the internal liquid and the wool, as well as the friction space, are more sufficient. When removing the wool, it is only necessary to drain the internal liquid and open the sealing door 408 to remove it.

[0038] like Figures 1 to 6 As shown, in this embodiment, the rotating module 8 includes a bushing 801, a lower through block 802, a middle guide rod 803, a side guide rod 804, a middle clamping block 805, a meshing guide wheel 806, and an embedded guide wheel 807. The lower through block 802 is provided below the front end of the bushing 801. The middle guide rod 803 is provided in the middle of the upper end of the bushing 801. The side guide rods 804 are provided on the left and right sides of the upper end of the bushing 801. The middle clamping block 805 is provided in the middle of the middle guide rod 803. The meshing guide wheel 806 is provided on the inner side of the middle clamping block 805. The embedded guide wheel 807 is provided on the front and rear sides of the outer end of the side guide rod 804.

[0039] The bushing 801 and the lower through block 802 are integrated into one piece. The left and right sides of the upper end of the bushing 801 are 5 cm higher than the middle part, which is used to install the side guide rod 804. The front and rear sides of the middle guide rod 803 and the side guide rod 804 are reinforced with the bushing 801 by bolts. The installation areas of the middle guide rod 803 and the side guide rod 804 and the bushing 801 are all provided with longitudinal slots. The embedded guide wheels 807 are symmetrically distributed, and two embedded guide wheels 807 are installed on the front and rear of each side guide rod 804.

[0040] The guide rod 803 passes through the interior of the meshing guide wheel 806 and fixes the contact ends of the two, making them an integrated structure to facilitate subsequent power transmission. Then, a sprocket is installed at one end of the guide rod 803, which works in conjunction with the sprocket installed on the transmission end of the drive motor 7. The two are connected by a chain, so that the power of the drive motor 7 can drive the meshing guide wheel 806 in the rotating module 8 to rotate. The meshing guide wheel 806 meshes with the external toothed ring 406 set at the outer end of the fulling module 4, thereby driving the fulling module 4 to start rotating and thus start the fulling of the wool particles. At the same time, the side guide rod 804, in conjunction with the embedded guide wheel 807, can play a stabilizing role on the front and rear sides of the lower end of the fulling module 4.

[0041] like Figure 8 and Figure 9 As shown, in this embodiment, the inner cylinder module 9 includes an inner cylinder ring 901, a permeable plate 902, an inner lining ring 903, a separator rod 904, and an arc-shaped groove 905. The permeable plate 902 is provided in the middle of the inner cylinder ring 901, and the inner lining ring 903 is distributed in a ring in the middle of the inner side of the permeable plate 902. The separator rod 904 is welded and installed on the outer side inside the inner lining ring 903. The arc-shaped groove 905 is symmetrically opened on the inner side of the front end of the inner cylinder ring 901.

[0042] The inner lining ring 903 is welded and reinforced with the partition rod 904. Then, the permeable plate 902 is fitted and installed on the outside. The two ends are reinforced by welding the inner cylinder ring 901 and the partition rod 904 to form a cylindrical structure. Then, the assembly strip 10 is inserted into the inner side for splicing and assembly through the arc groove 905 formed by welding the partition rod 904 with the inner cylinder ring 901 and the inner lining ring 903. The inner side of the assembly strip 10 is provided with striped protrusions.

[0043] The separator bar 904 is welded and reinforced together with the inner cylinder ring 901, the permeable plate 902 and the inner lining ring 903 to form a cylindrical structure. Then, the assembly strip 10 is inserted into the arc groove 905 in sequence to complete the installation. Since the assembly strip 10 is an assembly structure and the inner side of the assembly strip 10 has striped protrusions, it can better allow the wool particles to rub against it during the felting process. When it is necessary to adjust the internal friction parts later, they can be replaced as needed. It is also quicker to replace them when they are worn out.

[0044] The electrical components mentioned in this article are all connected to an external controller and mains power, and the controller can be a conventional known device such as a computer that provides control.

[0045] The working principle of the technical solution provided by this invention is as follows: The rotating motor 6 drives the integrated structure formed by the balance module 2 and the horizontal clamping module 3 to move left and right, creating a swinging structure. Simultaneously, two sets of fulling modules 4 are installed at the left and right ends of the swinging structure. According to production needs, the two sets of fulling modules 4, along with the symmetrically installed transmission motor 7 and rotating module 8 below, can be preset to form two working modes: the left side for ordinary wool fulling and the right side for granular wool fulling. Compared to the traditional single-tube design, this eliminates the need for frequent changes to internal parameters and mechanical structures, making overall operation more convenient and improving the device's applicability in fulling wool products. Secondly, before starting work, the sealing door 408 is opened. The wool pellets to be felted are placed inside the felting module 4. Then, the rotating motor 6 drives the integrated structure formed by the balance module 2 and the lateral clamping module 3 to lift and lower. Depending on the production needs, the felting modules 4 installed on the left and right sides with different operating modes are moved downwards and come into contact with the rotating module 8 installed below. Then, the drive motor 7 starts to work. Since the sprocket installed on its transmission end is connected to the central guide rod 803 installed on the rotating module 8 through a chain, the power is transmitted, causing the central guide rod 803 to drive the meshing guide wheel 806 in the middle to start rotating. The meshing guide wheel 806 meshes with the external toothed ring 406 set on the outer end of the felting module 4, thereby driving the felting module 4 to start rotating, thus starting the felting work of the wool pellets.

[0046] About felting solution: The fulling solution used in this invention for fulling granulated wool preferably comprises: 2-5%wt of a cashmere / wool-specific fulling agent (e.g., containing surfactants, lanolin derivatives, etc., commercially available brands such as AATCC standard fulling agents or similar products), with soft water or deionized water as the solvent, and a pH value controlled between 4.5 and 5.5. The specific ratio can be adjusted according to the type of granulated wool, fiber fineness, and desired fulling degree. For example, for finer granulated wool that is easily felted, the concentration of the fulling agent can be appropriately reduced to 2-3%wt; for slightly coarser granulated wool with a slower fulling reaction, the concentration can be appropriately increased to 4-5%wt. Appropriate amounts of antistatic agents (such as polyethylene glycol) and antifungal agents (such as quaternary ammonium salts) can also be added to the fulling solution as needed, typically not exceeding 10% of the fulling agent dosage.

[0047] Regarding fulling time and temperature: The time and temperature are key parameters affecting the final result of fulling wool pellets, and need to be precisely controlled according to the specific characteristics of the wool pellets and the desired degree of fulling. Preferably, the fulling temperature should be controlled between 38-45℃. Too low a temperature results in a slow fulling reaction and low efficiency; too high a temperature may damage the wool fibers, worsen the hand feel, or even cause excessive felting. The fulling time is typically 30-90 minutes. Too short a time results in insufficient fulling and an unsatisfactory pellet effect; too long a time may cause over-fulling, affecting the fluffiness and softness of the wool pellets. For example, for wool pellets with finer fibers that are easier to full, treatment at 42℃ for about 40-60 minutes is recommended; for wool pellets with coarser fibers that are slower to full, treatment at 40℃ for about 60-90 minutes is recommended. In practice, operators should determine the optimal fulling endpoint based on the specific characteristics of the wool pellets, combining visual observation (such as wool fluffiness and pellet shape) and tactile feel, and adjust the time and temperature parameters as necessary.

[0048] Regarding the assembly of the strip panels: The assembly strip 10 described in this invention is preferably made of wear-resistant plastic (e.g., polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), etc.), but ceramic or metal materials (e.g., stainless steel) can also be used. The assembly strip is elongated, with a trapezoidal cross-section or raised stripes to ensure a tight fit with the arcuate groove 905 of the inner cylinder module 9, providing sufficient friction to promote relative movement between the wool particles and the inner cylinder module, thereby achieving an effective felting effect. The size of the assembly strip can be adjusted according to the size of the inner cylinder module and the space of the felting cavity to ensure that the assembly strips are tightly arranged and cover the entire inner surface of the inner cylinder module. The assembly strip is detachable for easy replacement and maintenance.

[0049] Regarding the inner cylinder module: The inner cylinder module 9 described in this invention is preferably made of stainless steel or other corrosion-resistant metals, but plastic or ceramic materials can also be used. The inner cylinder module is cylindrical in shape, and its internal space constitutes a felting cavity. The diameter and height of the inner cylinder module can be adjusted according to the size of the felting module and the space of the felting cavity to ensure that the felting cavity has sufficient volume to accommodate the wool particles and felting liquid, and to ensure the effective execution of the felting process. The inner surface of the inner cylinder module is smooth to improve the flowability of the wool particles and reduce frictional resistance. An arc-shaped groove 905 is provided at the front end of the inner cylinder module for installing the assembly strip 10, forming a friction surface to promote the felting effect of the wool particles.

[0050] Regarding the drive motor and rotating module: The power of the drive motor 7 described in this invention can be adjusted according to the size of the felting module and the felting load, preferably 0.5-2kW. The speed of the drive motor can be adjusted according to the felting efficiency and stability, preferably 50-150rpm. The structural design of the rotating module 8 should be able to withstand the power and speed of the drive motor and ensure its stable operation.

[0051] Experimental Results and Discussion To verify the effectiveness of the special felting and washing process and supporting equipment for granular wool provided by this invention, we conducted a series of comparative experiments. The experimental materials included two typical granular wool fabric samples (Sample A: finer fibers, easily felted; Sample B: coarser fibers, slower felting) and a commercially available ordinary single-cylinder felting machine (existing technology) and the double-cylinder felting equipment designed in this invention (this invention). During the experiments, we controlled parameters such as the composition of the felting solution (3%wt cashmere / wool-specific felting agent, pH 5.0, soft water), temperature (40℃), and basic felting time, focusing on comparing the felting effect, production efficiency, and equipment applicability.

[0052] Comparison of felting effects: Figure 10 and Figure 11 The presentation shows a comparison of the appearance of sample A before and after fulling treatment using existing technology equipment and the equipment of this invention. From Figure 10 It can be seen that sample A, processed using existing technology and equipment, has an indistinct grainy texture after felting, with some areas showing excessive felting resulting in a stiff feel, and slight signs of damage at the edges. Meanwhile... Figure 11 In the sample A processed using the equipment of this invention, the granular appearance is clearly visible, the fabric is fluffy overall, the short pile layer unique to granular wool is more delicate, the hand feel is soft, and there is no damage.

[0053] In addition to appearance, we also tested the felting rate, warmth retention, and pilling resistance. The test results are summarized in the table. It can be seen that the two samples treated with the equipment of this invention have more ideal felting rate control, significantly improved warmth retention, and better pilling resistance than those treated with existing technology equipment.

[0054] The results of the felting rate, warmth retention, and anti-pilling properties of sample A before and after felting treatment using existing technology equipment and the equipment of this invention are summarized in the table below: index Existing technology equipment processing The device of this invention processes Flocking rate (%) 20% 30% Warmth retention (°C) 2.5 3.8 Anti-pilling Level 3 Level 4 Felting rate: Felting rate refers to the percentage reduction in length of wool fibers during the felting process. The felting rate of sample A processed by the equipment of this invention is significantly higher than that of existing equipment, indicating that the process of this invention can more effectively shrink wool fibers, forming a denser felted structure, thereby achieving a better felting effect.

[0055] Warmth retention: Warmth retention refers to the fabric's ability to resist heat loss. Sample A processed by the equipment of this invention exhibits significantly better warmth retention than existing equipment, indicating that the process of this invention can better maintain the fluffiness and warmth of wool fibers, making the fabric warmer.

[0056] Pilling resistance: Pilling resistance refers to the fabric's ability to resist pilling. Sample A processed by the equipment of this invention exhibits better pilling resistance than existing equipment, indicating that the process of this invention can better control the degree of felting, avoid excessive felting leading to fiber breakage, and thus reduce pilling.

[0057] Conclusion: By comparing indicators such as shrinkage rate, warmth retention and anti-pilling properties, it can be concluded that the special shrinkage washing process and supporting equipment for granular wool provided by this invention can effectively improve the shrinkage effect and product quality of granular wool, making it fluffier, warmer and more durable.
