Description

Technical Field

[0002] The present invention relates to the technical field of knitted fabrics, and particularly relates to a yarn pretreatment mechanism and a preparation method for a constant-temperature knitted fabric. Background Art

[0003] A knitted fabric is a fabric formed by bending yarns and interlacing them with each other using a loom, and is a basic component of textiles. With the development and progress of society, people's demand for high-quality, high-grade, and comfortable-to-wear textiles is also increasing. For textiles, being able to not overheat and cause excessive sweating when worn in hot weather is a criterion for judging the comfort of knitted fabrics.

[0004] Most traditional textiles are passive in temperature regulation, achieving heat preservation by passively blocking heat conduction and heat convection between the human body and the external environment. When the external temperature is very high, in order to maintain a constant body temperature, the human body needs to sweat, and the evaporation of sweat takes away heat to ensure the normal working state of the human body. However, this passive way of regulating the human body temperature easily makes people feel uncomfortable, and these knitted fabrics that can only let people dissipate heat passively cannot meet the requirements of modern people for the comfort performance of clothing.

The immersion water channel sequentially includes an installation part, an immersion part, and a lifting part. The installation part is connected to the outer periphery of the immersion part and is arranged towards the inside of the circulating water channel. A locking member is provided between the installation part and the bottom of the circulating water channel.

[0008] In an embodiment of the present application, the lifting part is a lifting bottom plate. The lifting bottom plate is threaded through the immersion part, and the lifting bottom plate and the immersion part are clamped to form a trapezoidal groove structure.

[0009] In an embodiment of the present application, at least two immersion water channels are provided in the circulating water channel. The slopes of the two immersion water channels are the same. The horizontal heights of the inlet ends of the two immersion water channels are the same. The two immersion water channels are arranged at intervals along the extension direction of the circulating water channel. A first lifting structure is provided between the two immersion water channels, and the first lifting structure is connected to the circulating water channel.

[0010] In an embodiment of the present application, the horizontal height between the circulating water channel and the circulating component gradually decreases along the direction towards the circulating component; A second lifting structure is provided at one end of the circulating water channel away from the circulating component relative to the yarn, and a plurality of active mechanisms are arranged in an array on the circulating water channel.

[0011] In an embodiment of the present application, at least two circulating water channels are provided. The two circulating water channels are connected to opposite ends of the circulating component along the transmission direction of the yarn; Each of the circulating water channels is provided with at least one immersion water channel.

[0012] In an embodiment of the present application, a concentration sensor is provided in the circulating component. The circulating component is provided with a feeding mechanism.

[0015] To achieve the above object, the present invention provides a method for preparing a thermostatic knitted fabric, including the yarn pretreatment mechanism of the above-mentioned thermostatic knitted fabric. The method for preparing the thermostatic knitted fabric includes: S1: Pass the yarn for weaving the knitted fabric into the atomization bin. The sulfuric acid solution is atomized by the atomizer, and the yarn is atomized. S2: Dry the atomized yarn through a drying mechanism to stabilize the state of the yarn. S3: Transmit multiple strands of processed yarn into the gathering mechanism. Use the gathering mechanism to gather multiple yarns into a row and transmit them into the fusion mechanism. S4: The circulation component transports the solution uniformly containing phase change microcapsules to the soaking water channel. The yarn passes through the soaking water channel and contacts and fuses with the active homogeneous phase change microcapsule solution. S5: Transmit the yarn led out of the soaking water channel into another drying mechanism. S6: Pass the dried yarn into a loom for knitting to obtain a thermostatic knitted fabric.

[0016] By adopting the above technical solutions, the present invention has the following advantages: 1. The processing mechanism structurally includes an atomization chamber, an atomizer, and a circulation mechanism. The yarn through-holes are arrayed between two opposite end faces of the atomization chamber. Multiple yarn through-holes correspond to multiple yarns. With this structure, multiple yarns can be processed simultaneously, effectively improving the processing efficiency. To ensure the uniformity and stability of the sulfuric acid concentration in the atomization chamber, one end of the atomizer passes through the bottom end face of the atomization chamber and is arranged obliquely upward towards the diagonal of the atomization chamber. Through this structure, the atomized sulfuric acid ejected is made to move uniformly towards the yarn as little as possible, avoiding the sedimentation of the atomized sulfuric acid at the bottom. A blower is provided at a position on the bottom end of the atomization chamber far from the atomizer, and the blower is arranged towards the lower part of the nozzle of the atomizer. While the atomizer sprays liquid upwards itself, a wind path is formed below the atomizer by the blower, which can further prevent the atomized sulfuric acid from sedimenting at the bottom and at the same time activate a large amount of atomized sulfuric acid, avoiding the aggregation of the atomized sulfuric acid in the atomization chamber. A recovery port is provided at the top of the atomization chamber far from the atomizer, and the recovery port is connected to the suction port of the circulation mechanism. Moreover, the atomizer is connected to the circulation mechanism. The circulation mechanism can input the sulfuric acid solution into the atomizer, and through the suction port, the circulation mechanism can extract the atomized sulfuric acid from the atomization chamber before it aggregates, which is beneficial to ensuring the stability of the atomized sulfuric acid concentration in the atomization chamber. When the yarn passes through the atomized sulfuric acid, the atomized sulfuric acid will uniformly etch out holes in the yarn. In this way, when the yarn passes through the fusion mechanism, the phase change particle capsules inside the fusion mechanism will fill the inside of the yarn, endowing the yarn itself with more characteristics.

[0017] 2. The fusion mechanism is arranged along the transmission direction of the yarn. A solution containing phase change particle capsules is provided inside the fusion mechanism. The phase change particle capsules are microcapsules obtained by reacting two monomers at the oil-water emulsion interface to form a polymer shell, thereby encapsulating the phase change material. They can be mass-produced industrially. For example, by using the interfacial polymerization method, an oil-soluble monomer (such as diisocyanate) and a water-soluble monomer (such as polyvinyl alcohol or amine) are dispersed in an emulsifying system, and a polymerization reaction occurs at the oil-water interface to form a stable polymer shell, encapsulating the phase change material (such as paraffin or stearic acid) inside to form a core-shell structured microcapsule. When the environmental temperature rises, the phase change material in the microcapsule, the inner core material (paraffin), will absorb heat and melt. The liquid core material can store a large amount of latent heat to achieve a cooling effect; when the temperature drops, the liquid core material solidifies again and releases latent heat to realize a temperature rise. The fusion mechanism immerses the microcapsules into the yarn processed by atomization in an immersion manner. The fabric woven with this kind of yarn can actively reduce body temperature to a certain extent, effectively ensuring a constant temperature effect and improving the user experience.

[0018] 3. The fusion mechanism itself includes a circulating water channel, a soaking water channel, and a circulating component. The circulating water channel is connected to the circulating component, and the soaking water channel is arranged within the circulating water channel. The orientation of the soaking water channel is along the transmission direction of the yarn and is inclined downward towards the circulating component. The mixed solution within the circulating component will be conducted to the soaking water channel through the liquid outlet structure. Although the soaking water channel is obliquely arranged, as long as the liquid flow rate introduced by the liquid outlet structure is large enough, a certain volume of the mixed solution can still be stably stored within the soaking water channel. The slope of the soaking water channel towards the circulating component is limited, and the yarn can be continuously and stably soaked in the mixed solution. Moreover, multiple liquid outlet structures can be arranged along the soaking water channel to ensure that the solution distribution within the soaking water channel is more uniform and stable. When microcapsules are in water, they will form an emulsion or suspension state. If water and microcapsules are filled in a container and then the yarn is directly placed therein for soaking, the solution is prone to stratification, resulting in uneven concentration within the solution and poor soaking effect. With the structure of the present application, after the solution enters the soaking water channel, it cannot stay within the soaking water channel for a long time and will be guided into the circulating water channel along the soaking water channel and then transported back to the circulating component by the circulating water channel. In such a structure, it can be ensured that the solution within the soaking water channel can maintain a state of uniform and stable concentration. Moreover, the volume of water that can be stored within the soaking water channel is limited, its solution update rate is fast, and only a small amount of solution is required to completely immerse the yarn, which can effectively improve the soaking and fusion effect of the yarn and effectively improve the quality of the thermostatic knitted fabric.

[0019] 4. Multiple yarns can be processed simultaneously within the processing mechanism to achieve the purpose of improving processing efficiency. At the same time, in order to enable these multiple yarns to enter the fusion mechanism simultaneously, a gathering mechanism is provided between the processing mechanism and the fusion mechanism. The gathering mechanism includes a tensioning structure and a wire gathering and guiding part. The tensioning structure is arranged corresponding to the yarn through holes. By using the tensioning structure, the state of the yarn can be ensured and damage to the yarn itself can be avoided. The wire gathering and guiding part is arranged towards the fusion mechanism. After the yarn passes through the tensioning structure, it is guided to the guiding wire groove arranged on the wire gathering and guiding part. After the yarns are gathered, they are uniformly transported to the fusion mechanism. By using this structure, the fusion mechanism can process multiple yarns simultaneously, improving the processing efficiency while ensuring the processing quality, enabling the knitted fabric to have a thermostatic effect, and improving the user experience.

[0020] 5. The pretreatment mechanism further includes a stabilizing mechanism, which stabilizes the properties of the yarn through a drying mechanism. After passing through the drying mechanism behind the processing mechanism, the state of the yarn is stabilized, the holes are uniform and do not expand further, ensuring the stability of subsequent fusion and avoiding yarn breakage. When passing through the fusion mechanism, the drying mechanism is used to dry the yarn, which can make the state of the yarn more stable, improve the fusion effect while making the yarn convenient to be transported to a loom for the production of thermostatic knitted fabric, effectively improving the processing quality.

[0024] The realization, functional characteristics and advantages of the object of the present invention will be further described with reference to the embodiments and the drawings. Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] Referring to Figures 1 to 9 , to achieve the above object, a yarn pretreatment mechanism for a constant temperature knitted fabric proposed by the present invention is used for processing yarns, and includes a processing mechanism 1, a fusion mechanism 5, and a stabilizing mechanism 4. The processing mechanism 1 includes an atomization chamber 11, an atomizer 12, and a circulation mechanism 2. The atomization chamber 11 is provided with a plurality of yarn through holes. The atomizer 12 is disposed through the atomization chamber 11 and is oriented towards the yarn through holes. A blower is provided in the atomization chamber 11 towards the atomizer 12. A recovery port is provided at a position of the atomization chamber 11 away from the atomizer 12. A sulfuric acid solution is provided in the circulation mechanism 2 and is communicated with the recovery port; The fusion mechanism 5 is arranged along the extension direction of the yarn through holes. The processing mechanism 1 is provided with a gathering mechanism 3 towards the fusion mechanism 5. The fusion mechanism 5 includes a circulating water channel 6, a soaking water channel 7, and a circulation component 8. The soaking water channel 7 is disposed through the circulating water channel 6. The height difference between the soaking water channel 7 and the circulation component 8 gradually decreases along the direction towards the circulation component 8. The circulating water channel 6 is communicated with the circulation component 8. A solution containing phase change particle capsules is provided in the circulation component 8. The circulation component 8 is provided with a liquid outlet structure 81 relative to the soaking water channel 7; The stabilizing mechanism 4 includes at least two drying mechanisms 41. One drying mechanism 41 is connected to the discharge port of the processing mechanism 1 and is located between the processing mechanism 1 and the gathering mechanism 3. The other drying mechanism 41 is connected to the discharge port of the fusion mechanism 5.

[0027] The processing mechanism 1 structurally includes an atomization chamber 11, an atomizer 12, and a circulation mechanism 2. The yarn through-holes are arrayed between two opposite end faces of the atomization chamber 11. Multiple yarn through-holes correspond to multiple yarns. With this structure, multiple yarns can be processed simultaneously, effectively improving the processing efficiency. To make the sulfuric acid concentration in the atomization chamber 11 uniform and stable, the atomizer 12 penetrates one end face at the bottom of the atomization chamber 11 and is arranged obliquely upward towards the diagonal of the atomization chamber 11. Through this structure, the atomized sulfuric acid ejected is directed towards the yarn as evenly as possible with as little as possible, avoiding the atomized sulfuric acid from settling to the bottom. A blower is provided at a position on the bottom end of the atomization chamber 11 far from the atomizer 12, and the blower is arranged below the nozzle of the atomizer 12. While the atomizer 12 sprays liquid upward itself, a wind path is formed below the atomizer 12 by the blower, which can further avoid the atomized sulfuric acid from settling to the bottom and at the same time activate a large amount of atomized sulfuric acid, preventing the atomized sulfuric acid from aggregating in the atomization chamber 11. A recovery port is provided at the top of the atomization chamber 11 far from the atomizer 12, and the recovery port is connected to the suction port of the circulation mechanism 2. Moreover, the atomizer 12 is connected to the circulation mechanism 2. The circulation mechanism 2 can input the sulfuric acid solution into the atomizer 12, and through the suction port, the circulation mechanism 2 can extract the atomized sulfuric acid from the atomization chamber 11 before it aggregates, which is beneficial to ensuring the stability of the atomized sulfuric acid concentration in the atomization chamber 11. When the yarn passes through the atomized sulfuric acid, the atomized sulfuric acid will uniformly etch holes in the yarn. In this way, when the yarn passes through the fusion mechanism 5, the phase change particle capsules inside the fusion mechanism 5 will fill the inside of the yarn, endowing the yarn itself with more characteristics.

[0028] The fusion mechanism 5 is arranged along the transmission direction of the yarn. The fusion mechanism 5 contains a solution with phase change particle capsules. The phase change particle capsules are microcapsules obtained by reacting two monomers at the oil-water emulsion interface to form a polymer shell, thereby encapsulating the phase change material. They can be mass-produced industrially. For example, using the interfacial polymerization method, oil-soluble monomers (such as diisocyanates) and water-soluble monomers (such as polyvinyl alcohol or amines) are dispersed in an emulsifying system, and a polymerization reaction occurs at the oil-water interface to form a stable polymer shell, encapsulating the phase change material (such as paraffin or stearic acid) inside to form a core-shell structure microcapsule. When the environmental temperature rises, the phase change material in the microcapsule, the inner core material (paraffin), will absorb heat and melt. The liquid core material can store a large amount of latent heat to achieve a cooling effect; when the temperature drops, the liquid core material solidifies again and releases latent heat to realize a temperature rise. The fusion mechanism 5 soaks the microcapsules into the yarn treated by atomization in an immersion manner. The fabric woven with this kind of yarn can actively reduce body temperature to a certain extent, effectively ensure the constant temperature effect, and improve the user experience.

[0029] The fusion mechanism 5 itself includes a circulating water channel 6, a soaking water channel 7, and a circulating component 8. The circulating water channel 6 is connected to the circulating component 8, and the soaking water channel 7 is arranged inside the circulating water channel 6. The orientation of the soaking water channel 7 is along the transmission direction of the yarn and is obliquely downward towards the circulating component 8. The mixed solution in the circulating component 8 will be conducted to the soaking water channel 7 through the liquid outlet structure 81. Although the soaking water channel 7 is obliquely arranged, as long as the liquid flow rate introduced by the liquid outlet structure 81 is large enough, a certain volume of the mixed solution can still be stably stored in the soaking water channel 7. The slope of the soaking water channel 7 towards the circulating component 8 is limited, and the yarn can always be stably soaked in the mixed solution. Moreover, multiple liquid outlet structures 81 can be arranged along the soaking water channel 7 to ensure that the solution distribution in the soaking water channel 7 is more uniform and stable. The microcapsules will form an emulsion or suspension state in the water body. If water and microcapsules are filled in a container and then the yarn is directly placed in it for soaking, the solution is likely to stratify, resulting in uneven concentration in the solution and poor soaking effect. With the structure of this application, after the solution enters the soaking water channel 7, it cannot stay in the soaking water channel 7 for a long time and will be introduced into the circulating water channel 6 along the soaking water channel 7 and then transported back to the circulating component 8 by the circulating water channel 6. In such a structure, it can be ensured that the solution in the soaking water channel 7 is in a state of uniform and stable concentration. Moreover, the volume of the water body that can be stored in the soaking water channel 7 is limited, its solution update rate is fast, and only a small amount of solution can completely immerse the yarn, which can effectively improve the soaking and fusion effect of the yarn and effectively improve the quality of the thermostatic knitted fabric.

[0030] Multiple yarns can be processed simultaneously in the processing mechanism 1 to achieve the purpose of improving processing efficiency. At the same time, in order to enable these multiple yarns to enter the fusion mechanism 5 simultaneously, a gathering mechanism 3 is provided between the processing mechanism 1 and the fusion mechanism 5. The gathering mechanism 3 includes a tensioning structure and a wire gathering and guiding part 23. The tensioning structure is arranged corresponding to the yarn through holes. By using the tensioning structure, the state of the yarn can be ensured and the yarn itself can be prevented from being damaged. The wire gathering and guiding part 23 is arranged towards the fusion mechanism 5. After the yarn passes through the tensioning structure, it is guided to the guiding wire groove arranged on the wire gathering and guiding part 23. After the yarns are gathered, they are uniformly transported to the fusion mechanism 5. With this structure, the fusion mechanism 5 can process multiple yarns simultaneously, improving the processing efficiency while ensuring the processing quality, enabling the knitted fabric to have a thermostatic effect and improving the user experience.

[0031] The pretreatment mechanism also includes a stabilizing mechanism 4, which stabilizes the properties of the yarn through the drying mechanism 41. After passing through the drying mechanism 41 after the processing mechanism 1, the state of the yarn is stabilized, the holes are uniform and do not expand further, ensuring the stability of subsequent fusion and preventing the yarn from breaking. When passing through the fusion mechanism 5, the drying mechanism 41 is used to dry the yarn, which can make the state of the yarn more stable, improve the fusion effect while making the yarn convenient to be transported to the loom for the production of thermostatic knitted fabric, effectively improving the processing quality.

[0032] Refer to in combination Figures 6 to 9 , the soaking water channel 7 is of a V-shaped groove structure. The soaking water channel 7 successively includes an installation part 71, a soaking part 72, and a lifting part 73. The installation part 71 is connected to the outer periphery of the soaking part 72 and is arranged towards the inside of the circulating water channel 6. A locking member is provided between the installation part 71 and the bottom of the circulating water channel 6. The lifting part 73 is connected to the bottom of the soaking part 72; the yarn is threaded through the soaking part 72.

[0033] The soaking water channel 7 is designed in a V-shaped groove structure. By using the V-shaped structure, the water level of the solution can be lifted. When there is only a small amount of solution, the yarn can also be completely immersed, saving space to the greatest extent and improving the soaking quality. A locking member composed of fixing rods is vertically arranged between the installation part 71 and the circulating water channel 6. By using the fixing rods, the soaking water channel 7 can be suspended above the circulating water channel 6. Multiple yarns are threaded through the soaking part 72. The solution completely immerses the soaking part 72. The lifting part 73 is used to lift the liquid level to ensure that the liquid can immerse the yarn, which can effectively improve the constant temperature effect of the knitted fabric.

[0034] Refer to in combination Figures 7 to 8 , the lifting part 73 is a lifting bottom plate. The lifting bottom plate is threaded through the soaking part 72. The lifting bottom plate and the soaking part 72 are clamped to form a trapezoidal groove structure.

[0035] The lifting part 73 is of a flat plate structure. By using the lifting bottom plate, the liquid level can also be lifted to form a trapezoidal structure, improving the utilization rate of the solution and ensuring the uniform and stable concentration of the solution.

[0036] Refer to in combination Figure 6 , at least two soaking water channels 7 are provided in the circulating water channel 6. The slopes of the two soaking water channels 7 are the same. The horizontal heights of the inlet ends of the two soaking water channels 7 are the same. The two soaking water channels 7 are arranged at intervals along the extension direction of the circulating water channel 6. A first lifting structure is provided between the two soaking water channels 7. The first lifting structure is connected to the circulating water channel 6.

[0037] Multiple soaking water channels 7 can be arranged at intervals in the circulating water channel 6 at the same time. Arranging multiple soaking water channels 7 can increase the soaking time of the yarn. And in such a structure, the slope of the soaking water channel 7 can be set higher, improving the renewal efficiency of the solution and making it easier for the solution to enter the circulating water channel 6. The length of the circulating water channel 6 that requires multiple soaking water channels 7 also needs to be longer. By increasing the soaking time, the soaking effect can be guaranteed, and while improving the fusion effect, the knitted fabric can achieve the effect of actively regulating the temperature. If multiple soaking water channels 7 need to be arranged in the circulating water channel 6 and the water channel length is long, in order to prevent the excessive sag of the yarn from causing scratching between the yarn and the bottom surface of the water channel and damaging the yarn, a lifting structure is provided between adjacent soaking water channels 7 to lift the yarn and prevent the yarn from touching the bottom.

[0038] Refer to in combination Figures 6 to 9 , the horizontal height between the circulating water channel 6 and the circulating component 8 gradually decreases along the direction towards the circulating component 8; One end of the circulating water channel 6 far from the circulating component 8 is provided with a second lifting structure 61 relative to the yarn, and a plurality of active mechanisms are arranged in an array on the circulating water channel 6.

[0039] The circulating water channel 6 is also arranged obliquely downward relative to the circulating component 8, which can enable the solution in the circulating water channel 6 to return to the circulating component 8 faster, improving the circulation efficiency of the solution. A second lifting structure 61 is provided at the end of the circulating water channel 6 far from the circulating component 8, which can be used to avoid scratching between the yarn and the end of the soaking water channel 7, enabling the yarn to enter the soaking water channel 7 more stably and improving the soaking effect. An active mechanism is arranged on the circulating water channel 6, and the active mechanism is an inflation structure. By using the active mechanism, the solution can be made more uniform, avoiding the solute from settling at the bottom of the circulating water channel 6 and ensuring the circulation effect of the solution.

[0040] Refer to in combination Figure 6 , at least two circulating water channels 6 are provided, and the two circulating water channels 6 are connected to opposite ends of the circulating component 8 along the transmission direction of the yarn; Each circulating water channel 6 is provided with at least one soaking water channel 7.

[0041] Arranging multiple circulating water channels 6 can extend the soaking time and make the temperature adjustment effect of the product more stable. At least one soaking water channel 7 is arranged on each circulating water channel 6 to ensure the processing effect of the yarn and improve the quality of the knitted fabric finished product.

[0042] Refer to in combination Figure 7 , a concentration sensor is arranged in the circulating component 8, a feeding mechanism 9 is arranged on the circulating component 8, the concentration sensor is electrically connected to the feeding mechanism 9, and a feeding one-way valve is arranged on the feeding mechanism 9 relative to the circulating component 8.

[0043] The circulating component 8 can also be called a solution tank, and a concentration sensor is arranged therein, which can be used to sense the concentration of the solute. When the concentration is insufficient, the feeding mechanism 9 supplements the solution to the circulating component 8 through the feeding one-way valve, which can make the solution concentration more stable and uniform, ensure the processing quality of the yarn, and enable the knitted product to achieve a constant temperature effect.

[0044] Refer to in combination Figures 1 to 4 , the circulating mechanism 2 includes an air extraction mechanism 21 and a liquid storage mechanism 25, the atomizer 12 is connected to the liquid storage mechanism 25, the air extraction mechanism 21 is connected to the atomization chamber 11, one end of the air extraction mechanism 21 communicates with the recovery port, the other end communicates with the liquid storage mechanism 25, and a cooling mechanism 22 is arranged between the air extraction mechanism 21 and the liquid storage mechanism 25; The cooling mechanism 22 is connected to the side wall of the atomization chamber 11. The cooling mechanism 22 includes a guiding portion 23 and a turning portion 24. The horizontal height of the guiding portion 23 gradually decreases along the direction from the air extraction mechanism 21 to the liquid storage mechanism 25. The turning portion 24 is connected between two adjacent guiding portions 23.

[0045] The air extraction mechanism 21 is used to recover the atomized sulfuric acid in the atomization chamber 11, and cooperate with the atomizer 12 and the blower to make the concentration of the atomized sulfuric acid in the atomization chamber 11 more uniform. The air extraction mechanism 21 can guide the sulfuric acid back into the liquid storage mechanism 25. The atomizer 12 can extract liquid from the liquid storage mechanism 25. Through this structure, the circulation of the sulfuric acid solution is realized. An exhaust port can be arranged on the liquid storage mechanism 25 to ensure the air pressure balance in the atomization chamber 11.

[0046] A cooling mechanism 22 can be arranged between the air extraction mechanism 21 and the liquid storage mechanism 25 to cool the atomized sulfuric acid and make them polymerize and then flow into the liquid storage mechanism 25. This can ensure the stability of the sulfuric acid solution and avoid potential safety hazards. The guiding portion 23 has a certain slope and can slowly transport the sulfuric acid. The turning portion 24 can make the cooling mechanism 22 have multiple guiding portions 23, which can effectively increase the flow path of the sulfuric acid solution, improve the cooling effect, ensure that the sulfuric acid can flow back into the liquid storage mechanism 25 in a polymerized liquid state, ensure the stability of the state of the sulfuric acid solution, avoid the splashing of the sulfuric acid solution, and ensure the safety of the equipment and personnel.

[0047] Refer to Figure 4 , the atomizer 12 includes a nozzle 13 and an atomization chamber 14. The atomization chamber 14 penetrates through the atomization chamber 11. One end of the atomization chamber 14 communicates with the liquid storage mechanism 25, and the other end communicates with a high-pressure air jet port. The liquid storage mechanism 25 is provided with a solution check valve facing the atomization chamber 14; The nozzle 13 is provided with a plurality of spray ports in an array.

[0048] The atomization chamber 14 is connected to the liquid storage mechanism 25. The liquid storage mechanism 25 inputs the sulfuric acid solution into the atomization chamber 14 through the solution check valve. The atomization chamber 14 is connected with a high-pressure air jet port. By using high-pressure air jet, the sulfuric acid solution can be broken up and sprayed out in an atomized state from the spray ports of the nozzle 13. In this way, atomized sulfuric acid can be quickly and evenly generated, and the concentration of the atomized sulfuric acid in the atomization chamber 11 is made more uniform, ensuring the pretreatment effect of the yarn and improving the subsequent fusion effect.

[0049] Refer to Figure 10 , the present invention also proposes a preparation method of a thermostatic knitted fabric. The specific structure of the yarn pretreatment mechanism of the preparation method of the thermostatic knitted fabric refers to the above-mentioned embodiments. Since the preparation method of the present thermostatic knitted fabric adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.

[0050] S1: Feed the yarn for knitting fabric into the atomization chamber 11. The sulfuric acid solution is atomized by the atomizer 12 and the yarn is atomized.

[0051] Preferably, when the yarn passes through the atomization chamber 11, the atomized sulfuric acid will etch uniformly and stably voids for uniformly accommodating the phase change microcapsules in the yarn, which can improve the subsequent yarn fusion effect and enable the knitted fabric to have a better function of actively regulating stability.

[0052] S2: Dry the atomized yarn through the drying mechanism 41 to stabilize the state of the yarn.

[0053] Preferably, drying the yarn ensures the stability of the yarn state and avoids the residual sulfuric acid on the yarn from continuing to react with the yarn, resulting in damage to the structure of the yarn itself.

[0054] S3: Transmit multiple processed yarns into the gathering mechanism 3. Use the gathering mechanism 3 to gather multiple yarns into a row and transmit them into the fusion mechanism 5.

[0055] Preferably, multiple yarns are processed simultaneously. In order to avoid the need for multiple fusion mechanisms 5 to further process the yarns, using the gathering mechanism 3 to gather the yarns and then transmit them into the fusion mechanism 5 can effectively improve the processing efficiency.

[0056] S4: The circulation component 8 transmits the solution uniformly containing the phase change microcapsules to the immersion water channel 7. The yarn is threaded through the immersion water channel 7 and contacts and fuses with the homogeneous phase change microcapsule solution containing activity.

[0057] Preferably, the circulation component 8 circulates quickly with a small amount of solution to ensure the uniform stability of the solution concentration, and a small amount of solution can completely immerse the yarn, which can save the use of the solution and reduce costs. Through this structure, the fusion effect can be ensured and the knitted product can have a better constant temperature effect.

[0058] S5: Transmit the yarn led out from the immersion water channel 7 into another drying mechanism 41.

[0059] Preferably, the soaked yarn will enter a drying mechanism 41 different from that in S2, so that the yarn is dried, the fusion effect is improved, and the yarn is convenient for further processing.

[0060] S6: Feed the dried yarn into a loom for knitting to obtain a constant temperature knitted fabric.

[0061] Preferably, the yarn at the drying temperature is input into the loom for weaving. Through the above structure, the knitted fabric can have the function of actively regulating temperature, which can improve the user experience.
