Description

Technical Field

[0001] This invention relates to the field of textile spinning technology, and more specifically to a composite twisting process for improving the anti-pilling and anti-fuzzing properties of silk yarn. Background Technology

[0002] The twisting and plying process uses a twisting and plying machine. The twisting and plying process is a textile technology that combines multiple single yarns into one yarn through twisting. It applies a twisting force to the silk yarn through a twister, making the fibers tightly bound together. Twisting and plying is the core process of silk yarn processing. After plying, the yarn strength is significantly enhanced, and its anti-friction and tensile properties are better than those of single yarns.

[0003] The specific steps of twisting in a twisting and plying machine are as follows: first, put the combined and wound silk yarn into the twister; then, connect the silk yarn guide on the winding drum to the twisting path component; start the equipment; the twister applies a stable torsional force to make the yarn wrap and bind together; after twisting is completed, the finished product is collected through the winding structure.

[0004] During the twisting process, the silk fibers of the aforementioned twisting and plying machine are prone to moisture loss. In the dry state, they have high friction and poor flexibility, and are prone to pilling and fuzzing during twisting, which affects the yarn quality and twisting efficiency. The twisting and plying machine does not have a targeted humidification structure, so it cannot improve the yarn humidity, which brings certain shortcomings to the twisting and plying process. Summary of the Invention

[0005] In view of the above-mentioned problems in the prior art, one objective of the present invention is to provide a composite twisting process to improve the anti-pilling and anti-fuzzing properties of silk yarn, so as to solve the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides a composite twisting process for improving the anti-pilling and anti-fuzzing properties of silk yarn, comprising a twisting and plying machine body and a twister, and further comprising: a placement seat disposed on the twisting and plying machine body; a humidifier detachably disposed on the placement seat; a fog guide disposed on the placement seat, which engages with the fog guide; an interface portion on the fog guide communicating with the spray hole of the humidifier; and an opening portion on the twister communicating with the interface portion. During operation, the mist generated by the humidifier enters the twister through the fog guide to humidify the silk yarn, thereby improving the twisting effect and enhancing the anti-pilling and anti-fuzzing properties.

[0007] Preferably, the placement base has a placement part adapted to the humidifier.

[0008] Preferably, the humidifier is provided with a ring clamp, and the placement part is provided with a clamp plate that engages with the ring clamp.

[0010] Preferably, the interface portion is a circular hole structure that is adapted to the spray hole on the top cover.

[0011] Preferably, the fog guide has a guide port that communicates with the interface portion.

[0012] Preferably, the guide opening is a flat, flared structure with an upper and lower arc shape, and its opening size is adapted to the opening portion.

[0013] Preferably, the twister is provided with a winding drum on which silk yarn is wound.

[0014] Preferably, the twisting and plying machine body is provided with a cross frame, and the cross frame is provided with guide wheels.

[0015] Preferably, the crossbar is also provided with a limiting ring to limit the position of the silk yarn.

[0016] In the above technical solution, the present invention provides a composite twisting process for improving the anti-pilling performance of silk yarn, which has the following beneficial effects: The invention uses a placement seat set on the body of the twisting and plying machine, and a humidifier is installed on the placement seat in a detachable manner. At the same time, a clamping seat and a mist guide are used to achieve a snap-fit ​​fixation, so that the interface of the mist guide is accurately connected to the spray hole of the humidifier. Together with the opening on the twister and the interface, a through mist channel is formed. During the operation, the mist is directly sent into the interior of the twister through the mist guide and acts on the yarn surface, so that the silk yarn always maintains a suitable humidity during the twisting process, reduces dry friction between fibers, reduces hair generation and fiber slippage, thereby improving the problem of yarn pilling and improving the overall twisting quality.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-7 The composite twisting process improves the anti-pilling and anti-fuzzing properties of silk yarn. It is used to solve the problems that silk fibers are prone to moisture loss during twisting in twisting and plying machines. In the dry state, they have high friction and poor flexibility, which makes them prone to pilling and fuzzing during twisting, affecting yarn quality and twisting efficiency. There is no targeted humidification structure on twisting and plying machines, which cannot improve yarn humidity and brings certain shortcomings to the twisting and plying process.

[0022] As a further technical solution proposed in this invention, the device includes a twisting and plying machine body 1 and a twister 3, and further includes: a placement seat 4, which is disposed on the twisting and plying machine body 1; a humidifier 5, which is detachably disposed on the placement seat 4; a retainer 4.1 disposed on the placement seat 4; a mist guide 6, which engages with the retainer 4.1; the mist guide 6 has an interface portion 6.2 communicating with the spray hole 5.2 of the humidifier 5; the twister 3 has an opening portion 3.1 communicating with the interface portion 6.2; during operation, the mist generated by the humidifier 5 enters the twister 3 through the mist guide 6 to humidify the silk yarn, thereby improving the twisting effect and improving the anti-pilling performance. Specifically, By setting a placement seat 4 on the twisting and plying machine body 1, and detachably installing a humidifier 5 on the placement seat 4, and using a locking seat 4.1 to lock and fix the mist guide 6, the interface 6.2 of the mist guide 6 and the spray hole 5.2 of the humidifier 5 are accurately connected and aligned. Together with the opening 3.1 and interface 6.2 on the twister 3, a through mist channel is formed. During operation, the mist is directly sent into the twister 3 through the mist guide 6 and acts on the yarn surface, so that the silk yarn always maintains a suitable humidity during the twisting process, reducing dry friction between fibers, reducing hair generation and fiber slippage, thereby improving the problem of yarn pilling and improving the overall twisting quality.

[0023] In this embodiment, the mist generated by the humidifier 5 enters the internal space of the twister 3 directly through the opening 3.1 via the mist guide 6. The rotating shaft inside the twister 3 drives the winding drum 7, which is wrapped with silk yarn, to rotate synchronously under the power drive. This allows the silk yarn to be continuously and evenly wrapped with mist while it is being twisted. Under this structure, the continuously sprayed mist will not be directly blown away by the high-speed rotating silk yarn, but will form a stable, soft and evenly distributed humidifying atmosphere inside the twister 3. This allows the silk yarn to maintain a moderately moist state at the moment of twisting and binding. This structure can not only avoid the yarn from becoming too wet and sticking together due to excessive local humidification, but also reduce the dry friction and pilling phenomenon between fibers, thereby improving the anti-pilling performance of the silk yarn.

[0024] In another embodiment of the present invention, the placement base 4 has a placement portion 4.3 adapted to the humidifier 5, the humidifier 5 is provided with a ring clamp 5.3, the placement portion 4.3 is provided with a clamping plate 4.5 that engages with the ring clamp 5.3, the humidifier 5 is provided with a top cover 5.1, and the placement portion 4.3 is provided with an annular portion 4.4 adapted to the top cover 5.1. Furthermore, the placement portion 4.3 on the placement base 4 provides a stable positioning for the humidifier 5. The engagement of the ring clamp 5.3 and the clamping plate 4.5 on the humidifier 5 enables quick assembly and disassembly of the humidifier 5, while preventing the humidifier 5 from shaking or shifting during operation, ensuring accurate and stable humidification. The annular portion 4.4 wraps around and limits the spray nozzle of the top cover 5.1 on the humidifier 5.Figure 3 As described above, the installation stability is further improved; the humidifier 5 is provided with a knob 5.4, which is used to realize the on / off control of the humidifier 5 and the graded adjustment of the spray intensity. For example, turning it to the right will start the machine, and continuing to turn it will gradually increase the spray intensity level to meet the humidification needs under different working conditions.

[0025] In another embodiment of the present invention, the twisting and plying machine body 1 is provided with a base 2 and a control screen 1.1, which is the prior art. The twister 3 is set on the base 2, and the control screen 1.1 is used for the operator to intuitively set process parameters such as twisting speed, twisting intensity and running time, so as to realize the automated and intelligent control of the equipment and improve the convenience of operation and processing accuracy.

[0026] In another embodiment of the present invention, the interface portion 6.2 is specifically a circular hole structure, which is adapted to the spray hole 5.2 on the top cover 5.1. The mist guide 6 has a guide port 6.1 that communicates with the interface portion 6.2. Furthermore, the interface portion 6.2 adopts a circular hole structure and is adapted to the spray hole 5.2 on the top cover 5.1, which allows the mist to enter the mist guide 6 smoothly and centrally, avoiding mist leakage and improving mist transmission efficiency. The guide port 6.1 on the mist guide 6 communicates with the interface portion 6.2 to guide the mist in a directional manner, so that the mist is accurately delivered into the twisting area inside the twister 3, ensuring accurate humidification position and uniform and stable humidification effect. Figure 7 The status is as shown.

[0027] In another embodiment of the present invention, preferably, the guide port 6.1 is a flat flared structure with an upper and lower arc shape, the opening size of which is adapted to the opening 3.1. Furthermore, the guide port 6.1 can spread the mist evenly, increase the contact area with the silk yarn, and the spray diffuses linearly from top to bottom. The vertically mounted winding drum 7 rotates under the drive of the inner shaft of the twister 3, so that the linear spray is distributed around the winding drum 7, thereby filling the interior of the twister 3 with spray and achieving all-round uniform humidification of the silk yarn wound on the winding drum 7. In addition, the arc-shaped flared port fits and connects better with the opening 3.1, reducing the leakage of mist and further improving the humidification utilization rate.

[0028] In another embodiment of the present invention, the card holder 4.1 is provided with a slot 4.2 for engaging with the protrusion of the fog guide 6, such as... Figure 3 As shown in the diagram, the stability of the fog guide 6 after it is installed in the mounting bracket 4.1 is improved by engaging the protrusion of the fog guide 6 with the recessed slot 4.2.

[0029] In another embodiment of the present invention, a winding drum 7 is provided on the twister 3, and silk yarn is wound on the winding drum 7. Furthermore, a winding and twisting machine body 1 is also provided with a winding and twisting mechanism (not shown in the figure) for winding the silk yarn. The twisting and twisting process first places the two types of silk yarn that need to be combined and wound on the winding and twisting mechanism, and then the silk and yarn are combined and wound on the winding drum 7 by the winding and twisting mechanism. Then the winding drum 7 is placed in the twister 3, and the silk yarn on the winding drum 7 is twisted by the twister 3.

[0030] In another embodiment of the present invention, a crossbeam 1.2 is provided on the body 1 of the twisting and plying machine, and a guide wheel 1.4 is provided on the crossbeam 1.2. Furthermore, the guide wheel 1.4 can stably guide and tension the combined yarn, so that the yarn remains straight and does not tangle during the conveying process, ensuring that the yarn smoothly enters the subsequent winding and twisting process, effectively avoiding yarn deviation, loosening or breakage, and improving the continuity of twisting and plying and the quality of the finished product.

[0031] In another embodiment of the present invention, a limiting ring 1.3 for limiting the silk yarn is further provided on the cross frame 1.2. Further, as... Figure 6 As shown in the figure, the limiting ring 1.3 can radially limit the silk yarn during the conveying process, preventing the silk yarn from deviating to the left or right, jumping or detaching from the guide wheel 1.4 during the yarn feeding process, so that the silk yarn is always kept within the set route for stable conveying, further avoiding yarn tangling, deviation and fuzz breakage, and ensuring continuous and stable twisting and plying process.

[0032] When using the twisting and plying machine body 1 for the twisting and plying process of silk yarn, the following process considerations should be taken into account to ensure processing quality and stable equipment operation. First, the twisting speed and twisting time should be reasonably set through the control panel 1.1 according to the material, linear density, and number of plies of the silk and yarn. This avoids excessive speed leading to excessive yarn tension and breakage, or insufficient twisting and loose bonding due to excessive speed. Second, during the operation of the humidifier 5, the spray intensity should be adjusted to a moderate level through the knob 5.4 to ensure that the mist concentration meets the humidification needs of the yarn without causing water accumulation inside the twister 3 or excessive moisture and sticking of the yarn due to excessive spray volume. After being combined by the doubling mechanism, the yarn enters the crossbeam 1.2. When installing the device, the yarn should be accurately threaded into the limiting ring 1.3 and aligned with the guide wheel 1.4 to prevent the yarn from running off-center or jumping, which could lead to increased fuzz or broken yarn. Additionally, when assembling the mist guide 6 with the mounting bracket 4.1 and the humidifier 5 with the placement seat 4, ensure they are properly engaged to prevent mist leakage and reduced humidification effect due to loose assembly. Before operating the equipment, check the secure installation of the winding drum 7 within the twister 3 to ensure it rotates smoothly with the shaft, allowing the mist to evenly surround the yarn for comprehensive humidification. Finally, after processing, promptly turn off the humidifier 5 and regularly clean and maintain the mist guide 6, guide wheel 1.4, and limiting ring 1.3 to remove adhering fiber dust and ensure long-term stable operation of the device.

[0033] Furthermore, to further ensure the stability of the twisting quality and anti-pilling performance of silk yarn, the environmental parameters during processing need to be reasonably controlled. The temperature of the processing environment should be controlled between 22℃ and 26℃, and the relative humidity should be maintained at 60%-70%. The specific temperature and humidity should be set according to the needs of those skilled in the art. This environmental condition can help maintain the inherent flexibility of silk yarn and reduce fiber embrittlement and pilling caused by dry environment. It works synergistically with the internal humidification of humidifier 5 to further improve the humidification effect and twisting stability. At the same time, before entering the doubling mechanism, the silk and yarn need to be pre-treated to remove impurities, knots and loose fibers from the surface of the yarn. This prevents such impurities from being rolled into the yarn during doubling and twisting, which would lead to uneven yarn structure and cause pilling problems. The pre-treated yarn needs to be placed in a cool place. Place it in a clean, dry environment to prevent secondary contamination. In addition, the selection of the winding drum 7 should be compatible with the linear density of the silk yarn. A winding drum with a smooth surface and moderate hardness should be selected to avoid the additional friction caused by the rough surface of the winding drum during the winding and twisting process, which could damage the fiber surface. During the twisting process, the operator needs to monitor the equipment operating parameters in real time through the control panel 1.1, and promptly detect and adjust abnormal situations, such as uneven yarn tension, abnormal mist spraying, and rotational deviation of the winding drum 7, to ensure that the twisting process is carried out continuously and stably. At the same time, the rotating shaft inside the twister 3, the winding drum 7, and the guide port 6.1 of the mist guide 6 should be inspected and lubricated regularly to reduce frictional wear between equipment parts, avoid affecting the processing quality due to equipment failure, extend the service life of the equipment, and ensure the consistency of the anti-pilling performance of the silk yarn.

[0034] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
