Description

Technical Field

[0001] The invention belongs to the technical field of spinning, and in particular relates to a fractal yarn preparation device and a preparation method based on a bionic principle. Background Art

[0002] Fractal yarn, inspired by bionic principles, is a textile material designed and manufactured based on the principles of bionics and fractal geometry. During the manufacturing process, fibers of staple yarns such as cotton, wool, Modal, Lyocell, and viscose tend to protrude. This phenomenon results in excessive hairiness on the yarn surface, impacting the fractal yarn's appearance, feel, and performance. Furthermore, fiber protrusion affects the yarn's smoothness and overall strength, limiting the fractal yarn's durability and service life.

[0003] Chinese invention patent publication number CN114990747B discloses a bionic yarn preparation method based on fractal principles and its spinning device. The device sets up a fiber coagulation mechanism to first loosen the structure of the yarn, then uses hot air flow to soften the fibers of the yarn, and uses two guide wheels to comb and smooth the fibers on the yarn upward, so that the protruding fibers are reintegrated into the yarn. Then, the two first electric shafts above are controlled to drive the two upper discs to rotate. The two discs rotate in opposite directions to tighten the yarn structure, thereby achieving the coagulation of the protruding fibers of the yarn.

[0004] However, the above technical solution has at least the following problems:

[0005] 1. When using a ventilator to heat the yarn, the hot air will quickly dissipate into the air, resulting in poor heating effect, serious waste of heat energy, and increased working environment temperature, affecting the physical comfort of the workers.

[0006] 2. A large amount of fibers float in the air with the hot air, threatening the health of workers. They will also fall on materials, products, and equipment, causing adverse effects.

[0007] 3. After repeated contact and friction with the disc and guide wheel, the yarn and fiber are prone to static electricity, which causes the fiber to curl up, the fiber cohesion effect is poor, and may even produce negative effects. Summary of the Invention

[0008] In order to solve the problems in the background technology, the present invention provides a fractal yarn preparation device and preparation method based on bionic principles.

[0009] The technical solution adopted in the present invention is:

[0010] A biomimetic fractal yarn production device includes a yarn loosening assembly, a combing assembly, a yarn tightening assembly, a heating cylinder, a heating device, a circulating power device, and a purification device. The heating cylinder, heating device, circulating power device, and purification device form a gas circulation system that circulates, heats, and purifies the gas. The gas inlet and gas outlet of the heating cylinder are located at both ends of the heating cylinder. Extending outward from the side of the heating cylinder near the gas outlet is an inlet support cylinder, and extending outward from the side of the heating cylinder near the gas inlet is an outlet support cylinder. Both the inlet and outlet of the inlet support cylinder are immersed in softener. The combing and yarn tightening assemblies are located within the heating cylinder.

[0011] Furthermore, the wire loosening assembly is located in the wire inlet support tube.

[0012] Furthermore, a secondary tensioning assembly is provided above the softener liquid level, and the yarn passes through the secondary tensioning assembly after coming out of the outlet support cylinder.

[0013] Furthermore, the purification equipment is a gas purification box, and a partition is vertically arranged in the middle of the gas purification box. The upper and side edges of the partition are in sealed contact with the inner wall of the gas purification box, and a space is left between the lower edge and the inner wall of the gas purification box. The gas purification box is filled with liquid, and the liquid level is always higher than the lower edge of the partition. A circulating power device is installed above the liquid level of the partition. The circulating power device transports gas from one side of the partition to the other side, thereby forming a high-pressure side and a low-pressure side. The gas inlet of the circulating power device is located below the liquid level on the low-pressure side, and the gas outlet is located above the liquid level on the high-pressure side.

[0014] Furthermore, the gas purification box further comprises a liquid pump and a filter. A liquid inlet and a liquid outlet are provided below the liquid level of the gas purification box, and the gas purification box, the liquid pump and the filter are connected in series to form a liquid circulation system.

[0015] Furthermore, a temperature sensor is provided inside the heating cylinder or at the front end of the gas inlet of the heating cylinder.

[0016] A method for preparing fractal yarn based on bionic principles comprises the following steps:

[0017] Step 1: Soak part or all of the yarn in softener;

[0018] Step 2: Extruding and dehydrating the yarn obtained in step 1, and rotating and loosening the yarn;

[0019] Step 3: heating and smoothing the yarn obtained in step 2;

[0020] Step 4: Tighten the yarn obtained in step 3;

[0021] Step 5: soaking the yarn obtained in step 4 in softener for a second time, and performing secondary tightening and squeezing dehydration;

[0022] Step 6: The yarn obtained in step 5 and other yarns that have not been treated above are paralleled and twisted to form fractal yarn;

[0023] Step 7: Drying the fractal yarn obtained in step 6.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] 1. In the present invention, the softener not only makes the yarn soft and smooth, improving its smoothness and wear resistance, thereby improving the appearance, feel, and performance of the textile, but also reduces static electricity. Wet yarns are further protected from static electricity, preventing static electricity generated by repeated contact and friction between the yarn and the mechanical structure, which can cause fiber warping and affect fiber cohesion. Furthermore, the present invention immerses the inlet and outlet of the heating cylinder's wire feed support tube in softener, forming a water seal. This allows the gas in the heating cylinder to flow only through the gas inlet and outlet of the heating cylinder, preventing shed fibers from being blown into the outside air. This significantly reduces heat loss, does not affect the workplace environment, and saves energy.

[0026] 2. The second soaking in softener can quickly cool the heated yarn, avoid fiber deformation caused by continuous heat, and avoid the heat affecting the performance of yarns of other materials during the subsequent doubling and twisting process.

[0027] 3. The function of the secondary tightening component is not only to tighten the yarn for the second time, but also to squeeze out the excess softener from the yarn that has been soaked in softener for the second time.

[0028] 4. The gas purification box of the present invention can remove impurities at any time without stopping the machine.

[0029] 5. The method of the present invention can improve the product performance of bionic fractal yarns obtained by different raw materials and paralleling and twisting methods, effectively reduce fiber leakage, make the fractal yarn soft and smooth, have a firm structure, and improve wear resistance and durability.

Therefore, they cannot be understood as limitations on the present invention.

[0034] In the description of this embodiment, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "connected" and "connect" should be understood in a broad sense.

[0035] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2This embodiment discloses a fractal yarn preparation device based on a bionic principle, comprising a loosening assembly 100, a combing assembly 200, a tightening assembly 300, a heating cylinder 400, a heating device 500, a circulating power device 600, and a purification device. The heating cylinder 400, the heating device 500, the circulating power device 600, and the purification device constitute a gas circulation system for circulating, heating, and purifying the gas, wherein the gas inlet and gas outlet of the heating cylinder 400 are located at both ends of the heating cylinder 400. An inlet support cylinder 410 extends outward from the side of the heating cylinder 400 near the gas outlet, and an outlet support cylinder 420 extends outward from the side near the gas inlet. The inlet of the inlet support cylinder 410 and the outlet of the outlet support cylinder 420 are both immersed in a softener, which is contained in a softening tank 700. The combing assembly 200 and the tightening assembly 300 are located inside the heating cylinder 400. Among them, the loosening component 100 and the tightening component 300 have the same principle, and the loosening of the yarn or the re-tightening of the yarn is achieved by rotating the yarn. Its structure can be two discs with the same rotational direction. The prior art in the background technology has disclosed this technical solution, or it can be two conveyor belts with the same rotational direction. The two discs or two conveyor belts are adjacent and squeeze the yarn, and the rotation of the yarn is achieved by applying opposite tangential friction forces to the yarn. The function of the combing component 200 is to comb the fibers on the yarn. It can be a drum structure that can roll with the yarn. The prior art in the background technology has disclosed this technical solution, or it can be a fixed multi-tooth structure.

[0038] Furthermore, the thread loosening assembly 100 is located in the thread inlet support tube 410, and can squeeze the yarn to squeeze out excess softener while rotating the yarn, and return it to the container containing the softener under the action of gravity.

[0039] Furthermore, a secondary tightening assembly 800 is provided above the softener liquid level, and the yarn passes through the secondary tightening assembly 800 after coming out of the outlet support tube 420. The function of the secondary tightening assembly 800 is not only to tighten the yarn for the second time, but also to squeeze out the excess softener from the yarn soaked in softener for the second time.

[0040] The biomimetic fractal yarn preparation device of this embodiment primarily involves the yarn processing stage before twisting the biomimetic yarn. After the yarn is soaked in softener, the loosening assembly 100 rotates the yarn through friction, loosening it and squeezing it to remove excess softener. The yarn then enters the heating cylinder 400 through the inlet support 410 of the heating cylinder 400. A gas circulation system continuously provides hot air to the heating cylinder 400, removing and purifying any loose fibers. The heated and softened yarn passes through the combing assembly 200 to smooth the fibers, allowing the damp fibers to adhere to the yarn. The tightening assembly 300 then rotates the yarn to re-tighten it. The re-tightened yarn passes through the outlet support 420 of the heating cylinder 400 and re-enters the softener for a second softening. The secondary tightening assembly 800 then tightens the yarn again, squeezing out any excess softener.

[0041] In this embodiment, the softener not only makes the yarn soft and smooth, improving its smoothness and wear resistance, thereby improving the appearance quality, feel, and performance of the textile, but also reduces static electricity. Wet yarns are further protected from static electricity, preventing static electricity from being generated after repeated contact and friction between the yarn and the mechanical structure, which can cause fiber warping and thus affect the fiber cohesion effect. Furthermore, in this embodiment, the inlet of the inlet support tube 410 and the outlet of the outlet support tube 420 of the heating cylinder 400 are both soaked in softener, forming a water seal. This allows the gas in the heating cylinder 400 to flow only through the gas inlet and gas outlet of the heating cylinder 400, preventing the detached fibers from being blown into the outside air. This greatly reduces heat loss, does not affect the working environment in the workplace, and saves energy. Furthermore, the secondary soaking in softener allows the heated yarn to cool quickly, preventing fiber deformation caused by continued heat, and preventing heat from affecting the performance of yarns of other materials during the subsequent doubling and twisting process.

[0042] As a further solution of this embodiment: the purification equipment is a gas purification box 900, and a partition 910 is vertically arranged in the middle of the gas purification box 900. The upper and side edges of the partition 910 are in sealed contact with the inner wall of the gas purification box 900, and a space is left between the lower side and the inner wall of the gas purification box 900. The gas purification box 900 is filled with liquid, and the liquid level is always higher than the lower edge of the partition 910. A circulation power device 600 is installed above the liquid level of the partition 910. The circulation power device 600 transports gas from one side of the partition 910 to the other side, thereby forming a high-pressure side 920 and a low-pressure side 930. The gas inlet of the circulation power device 600 is located below the liquid level of the low-pressure side 930, and the gas outlet is located above the liquid level of the high-pressure side 920.

[0043] The negative pressure side in the gas purification box 900 draws the gas into the gas purification box 900 through the action of negative pressure, and the positive pressure side discharges the gas through the action of positive pressure, thereby realizing the circulation of the gas. The gas entering the gas purification box 900 is broken in the liquid, impurities such as fibers are adsorbed by the liquid, and the clean gas is loosened downstream through the circulation power device 600. A structure that promotes bubble breakage, such as a mesh structure, suspended objects, etc., can be set below the liquid level on the negative pressure side, or the gas can be ejected from different directions through multiple holes at the gas inlet to reduce the volume of the bubbles and enhance the purification effect. The heating device 500 heats the circulating gas, and a temperature sensor 430 can be set in the heating tube 400 or in front of the gas inlet of the heating tube 400 to monitor the change in gas temperature and then adjust the power of the heating device 500. The heating device 500 can also directly heat the liquid in the gas purification box 900 and indirectly control the temperature of the air gas through the liquid.

[0044] Furthermore, it also includes a liquid pump 940 and a filter 950. A liquid inlet and a liquid outlet are provided below the liquid level of the gas purification box 900. The gas purification box 900, the liquid pump 940 and the filter 950 are connected in series to form a liquid circulation system. The liquid circulation system is started regularly to remove impurities in the liquid through the filter 950. During the intermittent stage of the liquid circulation system, the filter 950 can be cleaned or the filter screen can be replaced at any time to achieve impurity removal without stopping the machine. Of course, it is also possible to directly drain the liquid in the gas purification box 900 and then replenish clean liquid. Although the gas will not be purified for a period of time, the effect on the operation of the entire device is very small.

[0045] In this embodiment, it is necessary to set a transmission roller at an appropriate position to control the moving direction of the yarn.
