Description

Technical Field

[0001] This invention relates to the field of yarn dyeing technology, specifically to a dyeing device and method for cashmere, wool, and mulberry silk fancy yarns. Background Technology

[0002] Fancy yarns refer to yarns with special structures and appearances formed by using special raw materials, equipment, or processes during spinning and yarn making. Among them, cashmere, wool, and silk fancy yarns, with their softness and warmth of cashmere, crispness and durability of wool, and luster and smoothness of silk, have become the preferred raw materials for high-end textiles. Their typical structure is a slub yarn: silk fibers are used as the base yarn (ground yarn), relying on the excellent strength of silk to form the yarn skeleton, and a blend of cashmere and wool fibers is used as the finishing yarn. Through the periodic changes in the feeding speed during spinning, the cashmere and wool blend section forms a periodically raised slub structure, while the silk base yarn section maintains a uniform shape, ultimately forming a unique appearance texture with a fluffy texture at the slub section (rich in cashmere and wool) and a smooth texture at the flat section (mainly silk).

[0003] However, during the dyeing process, the slub section of this type of multi-component slub yarn is formed by the accumulation of cashmere and wool blended rovings. The fiber density is much higher than that of the flat base yarn. Furthermore, the scale layer on the surface of cashmere and wool fibers forms a natural penetration barrier, making it difficult for the dyeing solution to penetrate to the core of the slub section. This easily results in a white core defect with a darker outer layer and a lighter inner layer. Existing dyeing processes mostly use traditional immersion dyeing methods, which can only achieve uniform coloring on the surface of the yarn and cannot penetrate and strengthen the high-density fiber accumulation structure at the slub section.

[0004] To address these issues, a dyeing apparatus and method for cashmere, wool, and mulberry silk fancy yarns are provided. Summary of the Invention

A second inlet hole is provided on the end face of the rotating ring, and a first inlet hole is provided on the side of the staining enhancement seat at the position corresponding to the second inlet hole, for conveying staining solution into the first annular cavity.

[0010] As a further optimization of the present invention, the penetration enhancement component further includes a circulation pipeline, which is used to extract the dyeing solution in the dyeing tank and transport it to the rotating ring; the circulation pipeline includes a circulation pump, an infusion pipe and a suction pipe; one end of the infusion pipe is connected to the outlet end of the circulation pump, and the other end is fixedly connected to each of the first inlet holes; one end of the suction pipe is connected to the inlet end of the circulation pump, and the other end extends to the inner bottom surface of the dyeing tank, and the suction pipe is provided with a plurality of suction holes.

[0011] As a further optimization of the present invention, the penetration enhancement component further includes a vibration ring, which is used to perform ultrasonic vibration treatment on the slub joint of the fancy yarn passing through the through hole, so as to assist the dyeing solution penetration and improve the dyeing uniformity.

[0012] As a further optimization of the present invention, the dyeing enhancement seat is further provided with a plurality of second annular cavities distributed at equal intervals along the axial direction of the through hole.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1 To address the issue of thicker accumulation of cashmere and wool fibers at the slub joints in existing slub-type fancy yarns, hindering dye penetration, please refer to [link to relevant documentation]. Figures 1-3This invention provides a dyeing device for cashmere, wool, and mulberry silk fancy yarns. The fancy yarns are formed by fancy twisting cashmere fibers, wool fibers, and mulberry silk fibers to create slub yarns with constant slub intervals. The base yarn of the slub yarn is mulberry silk fiber, and the finishing yarn is a blended roving of cashmere and wool fibers. The device includes: Dyeing tank 1, which contains dyeing solution, is used to completely immerse and dye fancy yarns. A yarn conveying mechanism for driving fancy yarns in a step-by-step intermittent conveying manner with a step length matching the slub interval; Multiple sets of penetration enhancement components are arranged at equal intervals in the dyeing tank 1 along the conveying direction of the fancy yarn, and the spacing of each set of penetration enhancement components is adapted to the slub interval of the fancy yarn, which is used to perform radial penetration enhancement treatment on the slub of the fancy yarn. The penetration enhancement component includes a dyeing enhancement seat 2, which has multiple through holes 201 for fancy yarns to pass through, so as to dye multiple fancy yarns at the same time. The inner diameter of the through holes 201 is slightly larger than the maximum diameter of the fancy yarn slub. The inner wall of the through holes 201 is uniformly provided with multiple first spray holes 203 along the circumference, which are used to guide the dyeing liquid to be sprayed radially from multiple directions to the yarn slub, so as to achieve deep penetration of the dyeing liquid into the interior of the slub.

[0022] It should be noted that the device also includes a yarn guiding mechanism, which includes multiple sets of yarn guiding rollers. The yarn guiding rollers are respectively rotatably located at the yarn inlet end, yarn outlet end and inside of the dyeing tank 1. This is a conventional structure, and its working principle and specific structure will not be described in detail here.

[0023] In use, the fancy yarn to be dyed is passed sequentially through the through holes 201 of each dyeing reinforcement seat 2. The yarn conveying mechanism sets the step distance according to the constant slub interval of the yarn and drives the yarn to be conveyed intermittently. After each step is completed, the yarn stops moving. Specifically, a closed-loop control method using a servo motor and encoder or other implementation methods can be used. At this time, the through holes 201 of each penetration reinforcement component are precisely aligned with the slub segments on the yarn, while the base yarn segment is located in the area between adjacent dyeing reinforcement seats 2. The dyeing tank 1 is filled with dyeing liquid, and the fancy yarn is in a fully immersed state throughout the process. Under pressure, the dyeing liquid is sprayed synchronously from multiple first spray holes 203 evenly distributed circumferentially on the inner wall of the through holes 201, forming a multi-directional radial liquid flow impact, which directly acts on the cashmere and wool blended roving fiber bundles of the slub segments. The impact force of the liquid flow tears the gaps between the fibers, causing the dyeing liquid to penetrate from the surface of the slub segments to the core. At the same time, the mulberry silk base yarn segment located between adjacent dyeing reinforcement seats 2 naturally absorbs the dye in a mild dyeing liquid environment.

[0024] To enhance the penetration of the dye solution into the bamboo joints, and to utilize the thrust of the jetting liquid to stably press the bamboo joints against the vibrating ring 6, thereby improving the energy transfer efficiency of subsequent ultrasonic vibration, such as... Figures 3-5As shown, the penetration enhancement component also includes a rotating ring 3 and a rotating drive mechanism 5. The rotating ring 3 is used to control the periodic opening and closing of the first spray hole 203 in the circumferential direction to achieve pulse spraying treatment of the fancy yarn slub. The rotating drive mechanism 5 is connected to the rotating ring 3 and is used to drive the rotating ring 3 to rotate around the axis of the through hole 201. Multiple equally spaced first annular cavities 202 are opened in the dyeing enhancement seat 2 along the axial direction of the through hole 201. The first annular cavities 202 are coaxially arranged with the through hole 201. One end of the first spray hole 203 is connected to the first annular cavity 202, and the other end is connected to the inner wall of the through hole 201. The rotating ring 3 is rotatably disposed in the first annular cavity 202 and forms a sealing fit with the inner wall of the first annular cavity 202.

[0025] A second spray hole 301 is provided on the inner wall of the rotating ring 3 at the position corresponding to the first spray hole 203. The second spray hole 301 is periodically aligned or misaligned with the first spray hole 203 as the rotating ring 3 rotates, so as to realize the opening and closing control of the first spray hole 203. A second inlet hole 302 is provided on the end face of the rotating ring 3, and a first inlet hole 205 is provided on the side of the dyeing enhancement seat 2 at the position corresponding to the second inlet hole 302, for conveying dyeing solution into the first annular cavity 202.

[0026] In use, the rotary drive mechanism 5 drives the rotary ring 3 to rotate around the axis of the through hole 201. When the second spray hole 301 on the rotary ring 3 is aligned with the first spray hole 203 on the dyeing enhancement seat 2, the high-pressure dyeing liquid in the first annular cavity 202 is sprayed radially towards the bamboo segment through the aligned spray hole along the circumference of the through hole 201. When the second spray hole 301 rotates with the rotary ring 3 to the point of being misaligned with the first spray hole 203, the spraying stops. When the second spray hole 301 continues to rotate to align with the next first spray hole 203, the spraying continues. In this way, the intermittent pulse penetration treatment of the bamboo segment is achieved.

[0027] like Figure 6 As shown, the permeation enhancement component also includes a circulation pipeline 4, which is used to extract the dyeing solution in the dyeing tank 1 and transport it to the rotating ring 3. The circulation pipeline 4 includes a circulation pump 401, a delivery pipe 402, and a suction pipe 403. One end of the delivery pipe 402 is connected to the outlet end of the circulation pump 401, and the other end is fixedly connected to each of the first inlet holes 205. One end of the suction pipe 403 is connected to the inlet end of the circulation pump 401, and the other end extends to the inner bottom surface of the dyeing tank 1. The suction pipe 403 is provided with a plurality of suction holes 404.

[0028] When the circulation pipeline 4 is in use, the circulation pump 401 is started, and the suction pipe 403 draws the dyeing liquid from the bottom of the dyeing tank 1 through the suction holes 404 arranged at its bottom. During the extraction process, the dyeing liquid at the bottom of the tank can be continuously disturbed, which can effectively prevent the dye particles from settling and ensure that the concentration of dyeing liquid in all parts of the dyeing tank 1 is uniform. Under the pressure of the circulation pump 401, the dyeing liquid is stably transported to the first inlet hole 205 of each dyeing enhancement seat 2 through the delivery pipe 402, and flows smoothly into the first annular cavity 202 for storage, providing a stable and continuous supply of pressure dyeing liquid for the pulse radial injection controlled by the rotating ring 3.

[0029] Optionally, such as Figure 7 As shown, to achieve synchronous and precise driving of multiple sets of rotating rings 3, the rotating drive mechanism 5 specifically includes a drive motor 504, a first drive shaft 503, a second drive shaft 505, a gear 502, and a gear ring 501. The number of gear rings 501 is the same as the number of rotating rings 3. Each gear ring 501 is coaxially fixedly sleeved on the outer wall of the corresponding rotating ring 3. The gear 502 meshes with the gear ring 501 one by one to transmit power to the rotating ring 3. The first drive shaft 503 is connected to the output shaft of the drive motor 504. The first drive shaft 503 and the second drive shaft 505, and the second drive shaft 505 and the rotating shaft of the gear 502 are all vertically reversed through bevel gear reversing devices to adapt to the spatial layout in the dyeing tank 1 and avoid interference between the drive shaft and the yarn conveying path and the circulation pipeline 4.

[0030] Furthermore, the shafts of the first drive shaft 503, the second drive shaft 505, and the gear 502 are all supported and positioned by bearing seats, which are fixedly connected to the inner wall of the dyeing tank 1 or the dyeing enhancement seat 2.

[0031] When the rotary drive mechanism 5 is used, after the drive motor 504 is started, the power is transmitted sequentially through the first drive shaft 503 and the bevel gear commutator to the second drive shaft 505, and then distributed to the rotating shafts of each gear 502 through the bevel gear commutator. When the gear 502 rotates, it drives the meshing gear ring 501 to rotate synchronously, thereby driving each rotating ring 3 to rotate around the axis of the through hole 201.

[0032] Example 2 Based on Example 1, in order to further penetrate the dye solution after pulse spraying into the bamboo segment and improve the dyeing uniformity, such as Figure 4 , Figure 8 As shown, the penetration enhancement component also includes a vibration ring 6, which is used to perform ultrasonic vibration treatment on the slub joint of the fancy yarn passing through the through hole 201 to assist the dyeing solution penetration and improve dyeing uniformity.

[0033] Multiple equally spaced second annular cavities 204 are also provided in the dyeing enhancement seat 2 along the axial direction of the through hole 201. The second annular cavities 204 are coaxially arranged and connected with the through hole 201. The vibration ring 6 is embedded in the second annular cavity 204. An elastic ring 601 is provided between the outer wall of the vibration ring 6 and the inner wall of the second annular cavity 204. The elastic ring 601 can buffer rigid impact and prevent the vibration ring 6 from being damaged by high-frequency vibration.

[0034] The penetration enhancement component also includes a vibration drive mechanism 7 located above the dyeing enhancement seat 2. The vibration drive mechanism 7 is used to synchronously drive each vibration ring 6 to perform high-frequency vibration. The vibration drive mechanism 7 includes an ultrasonic transducer 701 and a vibration transmission frame 702. The vibration transmission frame 702 is fixedly located at the end of the amplitude transformer of the ultrasonic transducer 701. The bottom of the vibration transmission frame 702 is provided with multiple mounting seats 703 corresponding to each vibration ring 6. A movable rod 704 is movably passed through the mounting seat 703. An arc-shaped seat 705 is fixedly located at the bottom end of the movable rod 704. The arc-shaped seat 705 abuts against the outside of the vibration ring 6. A spring 706 is sleeved on the movable rod 704. One end of the spring 706 abuts against the mounting seat 703, and the other end abuts against the arc-shaped seat 705.

[0035] When the vibration ring 6 is used, the ultrasonic transducer 701 is activated. The high-frequency mechanical vibration generated by the transducer is amplified by the amplitude transformer and transmitted to the vibration transmission frame 702. The vibration transmission frame 702 drives the mounting seats 703 at the bottom to vibrate synchronously. The spring 706 on the movable rod 704 provides a continuous pre-tightening force, so that the arc-shaped seat 705 fits tightly against the outer wall of the vibration ring 6, ensuring that the vibration energy is transmitted to the vibration ring 6 without loss. The vibration ring 6 generates high-frequency vibration in the second annular cavity 204. The vibration is transmitted to the bamboo segment in the through hole 201 through the dyeing liquid medium. The ultrasonic cavitation effect is used to accelerate the diffusion of dye molecules, and finally achieves deep penetration of the dyeing liquid and improved dyeing uniformity.

[0036] Example 3 This invention also provides a dyeing method for cashmere, wool, and mulberry silk fancy yarns, comprising the following steps: S1. A constant slub yarn with mulberry silk fiber as the base yarn and cashmere fiber and wool fiber blended as the decorative yarn is sequentially threaded into the through holes 201 of each dyeing reinforcement seat 2 and completely immersed in the dyeing solution in the dyeing tank 1. S2. The fancy yarn is driven by the yarn conveying mechanism to perform intermittent step-by-step conveying with a step length matching the slub interval, so that each slub stops in turn at the set position of the corresponding through hole 201. S3. During the period when the bamboo joint is in place, the dyeing liquid is supplied to the first spray hole 203, so that it is sprayed radially in multiple directions along the circumferential direction from the inner wall of the through hole 201, penetrating the outer fiber layer of the bamboo joint to promote the dyeing liquid to penetrate into the bamboo joint, so as to achieve deep dyeing of the decorative yarn, while the base yarn naturally absorbs the color in the mild dyeing liquid environment outside the through hole 201. S4. Repeat steps S2-S3 until the entire fancy yarn has been dyed.

[0037] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.

The arc-shaped seat (705) abuts against the outside of the vibration ring (6). A spring (706) is sleeved on the movable rod (704).

9. A method for dyeing cashmere, wool, and mulberry silk fancy yarns, comprising using the dyeing apparatus for cashmere, wool, and mulberry silk fancy yarns as described in any one of claims 1-8, characterized in that, Includes the following steps: S1. A constant slub yarn with mulberry silk fiber as the base yarn and cashmere fiber and wool fiber as the decorative yarn is sequentially inserted into the through holes (201) of each dyeing reinforcement seat (2) and completely immersed in the dyeing solution in the dyeing tank (1). S2. The fancy yarn is driven by the yarn conveying mechanism to perform step-by-step intermittent conveying with a step length matching the slub interval, so that each slub stops in turn at the set position of the corresponding through hole (201). S3. During the period when the bamboo joint is in place, the dyeing liquid is supplied to the first spray hole (203) so that it is sprayed radially in multiple directions along the circumferential direction from the inner wall of the through hole (201) to penetrate the outer fiber layer of the bamboo joint and promote the dyeing liquid to penetrate into the bamboo joint, so as to achieve deep dyeing of the decorative yarn. The base yarn absorbs the dye naturally in the mild dyeing liquid environment outside the through hole (201). S4. Repeat steps S2-S3 until the entire fancy yarn has been dyed.
