[0023] The realization of the purpose, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0024] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to 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.

[0025] As Figures 2 to 9 shown, this embodiment proposes a production process for knitted flannel. S1: Select natural fiber or synthetic fiber as the yarn, and place the yarn obtained in S1 into an enzyme solution. The enzyme solution is 0.1% - 1% lipase, with a pH of 5.5 - 8 and the temperature controlled at 30°C - 50°C for 30 minutes to 2 hours for degreasing. Through experiments, it is confirmed that if the lipase concentration is too low, the degreasing effect may not be significant and the degreasing process will be slow; if the concentration is too high, it may lead to waste of enzymes and over-reaction, resulting in side effects and even damage to the fibers. Within the concentration range of 0.1% to 1%, it can ensure the full play of enzyme activity, avoid unnecessary side effects, and achieve a good degreasing effect. Lipase usually has the strongest activity under weakly acidic to neutral conditions (pH 5.5 - 8). Within this range, the activity of the enzyme can be maintained to the greatest extent, thereby improving the degreasing efficiency. The activity of lipase usually reaches the best between 30°C and 50°C. Within this temperature range, the lipase molecules are active, the catalytic reaction speed is relatively fast, and it can effectively decompose the fat and impurities on the fiber surface.

[0026] S2: Place the yarn obtained in S1 into clean water, adjust the water temperature to 50 - 60 °C, add a surfactant, and wash for 10 - 30 minutes. The surfactant used in this embodiment is preferably alkylbenzene sulfonate or fatty acid salt. The temperature of 50 - 60 °C can effectively help remove the grease and wax on the fiber surface, but is not too high to damage the fiber structure or cause thermal damage.

[0027] S3: After drying the yarn obtained in S2, place it into titanium dioxide with a concentration of 0.5% - 3%, adjust the pH value of the solution to 6 - 8, control the light intensity at 100 - 500 μW / cm², control the temperature between 20 °C and 30 °C, and react for 30 minutes to 2 hours for bleaching. The photocatalytic process of titanium dioxide can not only bleach organic substances, but also has strong selectivity and will not cause serious damage to the fiber. Compared with traditional chemical bleaching agents, titanium dioxide can provide a milder and more efficient bleaching in this process. Too low a concentration may not produce enough reactive oxygen species, resulting in an unsatisfactory bleaching effect; while too high a concentration may cause waste and even affect the stability of the reaction. The concentration range of 0.5% - 3% is a carefully designed range based on the photocatalytic efficiency of titanium dioxide and the actual application needs, which can ensure effective bleaching while maintaining cost - effectiveness. Within the pH range of 6 - 8, the catalytic activity of titanium dioxide is relatively stable, which helps to form more reactive oxygen species, thus improving the bleaching effect. At the same time, this pH range has less impact on the fiber, avoiding excessive damage to the fiber. The light intensity range of 100 - 500 μW / cm² can effectively stimulate the photocatalytic activity of titanium dioxide without damaging the fiber, providing an appropriate bleaching effect. Within the temperature range of 20 °C - 30 °C, the photocatalytic reaction can proceed efficiently while avoiding fiber damage or titanium dioxide degradation caused by too high a temperature. The appropriate temperature can also increase the molecular movement rate of the reactants in the solution, thus accelerating the bleaching process.

[0028] S4: Place the yarn obtained in S3 into a circular knitting machine or a warp knitting machine to knit it into double - sided flannelette, and then raise the nap of the double - sided flannelette through a napping machine. Knitting into double - sided flannelette through a circular knitting machine or a warp knitting machine and then raising the nap through a napping machine can significantly improve the fabric in terms of softness, warmth retention, appearance beauty, durability, breathability, etc. Such a process design makes the final product not only have excellent wearing comfort and functionality, but also have strong market attractiveness.

[0029] S5: Place the yarn obtained in S4 into the dyeing device, adjust the rotation speed of the stirring blade to be controlled between 30 and 50 revolutions per minute, the temperature of the dye 8 to be 60 to 80 °C, and perform dyeing for 30 to 60 minutes. Finally, dry and wind up the dyed double-sided flannel to complete the production of the knitted flannel. The role of stirring is to ensure the uniform distribution of the dye 8 on the surface of the yarn or fabric. If the stirring is too fast, the dye 8 may cause uneven local dyeing due to high-speed flow, and may even cause friction damage to the fabric; while too slow stirring may cause the dye 8 to stay on the fabric surface for too long, affecting the dyeing effect. Therefore, controlling the stirring speed at 30 to 50 revolutions per minute helps the dye 8 to uniformly penetrate into the yarn or fabric, ensuring uniform dyeing and avoiding color differences. The temperature of the dye is crucial for the dyeing effect of textiles. Too low a temperature may result in insufficient activity of the dye 8 molecules, and the dye 8 cannot effectively penetrate into the fiber interior, resulting in poor dyeing effect; while too high a temperature may cause problems such as fiber damage and dye 8 loss. In the temperature range of 60 to 80 °C, the activity of the dye 8 is relatively high, which can ensure that the dye 8 quickly and uniformly penetrates into the fiber structure of the yarn or fabric, and at the same time is not easy to damage the performance of the fiber, thus obtaining a good dyeing effect.

[0030] Another object of the invention in this embodiment: to provide a production device for knitted flannel.

[0031] The production device for knitted flannel includes the dyeing device in step S5, and the dyeing device includes a dyeing tank 1; In this embodiment, the feed inlet 11 and the discharge outlet 12 are arranged on both sides of the dyeing tank 1, the storage cavity 15 is arranged inside the dyeing tank 1, the dye 8 is arranged inside the storage cavity 15, and the stirring structure is arranged at the bottom of the storage cavity 15 for stirring the dye 8. The first transport roller 61 and the second transport roller 62 are respectively rotatably arranged on the sides of the storage cavity 15 close to the feed inlet 11 and the discharge outlet 12, and the immersion roller 63 is arranged between the first transport roller 61 and the second transport roller 62. The immersion roller 63 is rotatably connected to the storage cavity 15, and the immersion roller 63 is completely immersed in the dye 8. The first partition block 71 and the second partition block 72 are respectively arranged on both sides of the immersion roller 63 to isolate the upper layer of the dye 8 and ensure that the upper first sealing film 81 and the second sealing film 82 will not affect the knitted flannel entering the dye 8. The first sealing film 81 is arranged on the dye 8 between the first partition block 71 and the feed inlet 11, and the second sealing film 82 is arranged on the dye 8 between the second partition block 72 and the discharge outlet 12. In this embodiment, the first sealing film 81 and the second sealing film 82 isolate the air and the dye 8, reducing the contact between the dye 8 and the air, so that even when the dye 8 is in a stirred state, it is not easy to generate bubbles in the dye 8, improving the printing and dyeing efficiency of the knitted flannel.

[0032] In this embodiment, the cross-sections of the first partition block 71 and the second partition block 72 are in the shape of a right trapezoid, which is designed according to the position of the knitted fabric feeding to minimize the area of contact between the dye 8 and the air as much as possible. Both sides of the first partition block 71 and the second partition block 72 are fixedly connected to the material storage cavity 15, and there is a gap between the first partition block 71 and the second partition block 72 and the bottom of the material storage cavity 15. This right trapezoid design is to fit the channel formed when the knitted flannelette passes through the first transport roller 61 and the dipping roller 63, and to minimize the area of contact with the air in this channel, and to reduce the bubbles generated in the dye 8 due to the stirring of the stirring structure.

[0033] In this embodiment, the first sliding hole 13 and the second sliding hole 14 are arranged on both sides of the material storage cavity 15. The third partition block 31 is slidably arranged in the first sliding hole 13, and the fourth partition block 32 is slidably arranged in the second sliding hole 14. The cross-sections of the third partition block 31 and the fourth partition block 32 are both in the shape of an isosceles trapezoid, which is used to minimize the area of contact between the dye 8 and the air as much as possible. Such a design of the third partition block 31 and the fourth partition block 32 is to ensure that when the third partition block 31 abuts against the fourth partition block 32, under the action of the third partition block 31 and the fourth partition block 32, the area of contact between the dye 8 and the air is reduced, and the generation of bubbles is reduced; and when the third partition block 31 and the fourth partition block 32 move away from each other, it is also convenient to install the knitted flannelette with the first transport roller 61, the second transport roller 62, and the dipping roller 63.

[0034] In this embodiment, the adjusting screw rod 4 is rotatably arranged at the bottom of the dyeing box 1. The first thread 41 and the second thread 42 are respectively arranged on both sides of the adjusting screw rod 4. The first connecting frame 311 is fixedly arranged on the third partition block 31, and the second connecting frame 321 is fixedly arranged on the fourth partition block 32. The first connecting frame 311 is threadedly connected to the first thread 41, and the second connecting frame 321 is threadedly connected to the second thread 42. In this embodiment, the third partition block 31 and the fourth partition block 32 are synchronously controlled to move by the adjusting screw rod 4. Since the third partition block 31 and the fourth partition block 32 cannot drive the screw rod to rotate in the reverse direction, when the power supply of the screw rod is cut off, the positions of the third partition block 31 and the fourth partition block 32 are self-locked to prevent the occurrence of positioning deviation. Moreover, since the rotation stroke of the adjusting screw rod 4 is much larger than the movement stroke of the third partition block 31 and the fourth partition block 32, it is more accurate and reliable to control the movement of the third partition block 31 and the fourth partition block 32 by the adjusting screw rod 4.

[0035] In this embodiment, the sealing cover 2 is rotatably arranged on the top of the dye tank 8, and the sealing film is fixedly arranged on the sealing cover 2. The sealing film is made of rubber material to ensure the sealed connection between the sealing cover 2 and the dye tank 8. The first locking member 21 is rotatably arranged on the sealing cover 2, the second locking member 22 is fixedly arranged on the dyeing tank 1, and the first locking member 21 and the second locking member 22 are latched. The design of the first locking member 21 and the second locking member 22 ensures the sealing degree between the sealing cover 2 and the dye tank 8 and ensures a good sealing effect.

[0036] The first locking member 21 in this embodiment includes a screw rod 211 which is rotatably connected to the sealing cover 2. The first limit bolt 212 is rotatably arranged on the screw rod 211. The second locking member 22 includes a first limiting member 221 and a second limiting member 222. Both the first limiting member 221 and the second limiting member 222 are in an "L" shape. The first limiting member 221 and the second limiting member 222 are parallel to each other, and there is a gap between the first limiting member 221 and the second limiting member 222. When the screw rod 211 rotates between the first limiting member 221 and the second limiting member 222, the first limit bolt 212 can be rotated to abut against the first limiting member 221 and the second limiting member 222, which can ensure that the sealing cover 2 fully abuts against the dye tank 8, thereby ensuring the sealing of the dye tank 8. When the first limit bolt 212 rotates away from the first limiting member 221 and the second limiting member 222, the screw rod 211 can be rotated and disengaged from the first limiting member 221 and the second limiting member 222, ensuring that the sealing cover 2 can open the dye tank 8 so that the knitted flannel can be installed into the dyeing tank 1.

[0037] In this embodiment, the drying chamber 16 is arranged on the side of the dyeing box 1 close to the discharge port 12. The drying lamp 161 is fixedly arranged at the top of the drying chamber 16. The first film pressing roller 91 and the second film pressing roller 92 are arranged on the side of the material storage chamber 15 close to the discharge port 12. The second film pressing roller 92 is rotatably connected to the material storage chamber 15. The first adjusting block 912 and the second adjusting block 917 are rotatably arranged on both sides of the first film pressing roller 91. The first sliding rail 911 and the second sliding rail 916 are fixedly arranged on both sides of the material storage chamber 15. The first adjusting block 912 is slidably connected to the first sliding rail 911, and the second adjusting block 917 is slidably connected to the second sliding rail 916. The limiting groove 913 is arranged in the first adjusting block 912, and the third sliding hole 9131 is arranged on the limiting groove 913. The adjusting bolt 914 is rotatably arranged in the third sliding hole 9131, and the adjusting bolt 914 is threadedly connected to the first sliding rail 911. The second limiting bolt 915 is arranged in the limiting groove 913, and the second limiting bolt 915 is fixedly connected to the adjusting bolt 914. The structures of the first adjusting block 912 and the second adjusting block 917 are the same. When the knitted flannel passes between the first film pressing roller 91 and the second film pressing roller 92, the dyes 8 on both sides of the knitted flannel are extruded by the first film pressing roller 91 and the second film pressing roller 92, and the dyes 8 adhering to the knitted flannel will separate from the first film pressing roller 91 and the second film pressing roller 92 and fall back into the dye 8 chamber again, reducing the waste of the dye 8. Moreover, through the extrusion between the first film pressing roller 91 and the second film pressing roller 92, the dye 8 can be more thoroughly incorporated into the knitted flannel, ensuring more thorough dyeing of the knitted flannel and improving the dyeing effect.

[0038] The first sealing film 81 in this embodiment includes an isolation layer, a stabilizing layer, and a protective layer. The isolation layer is made of mineral oil material, and the thickness of the isolation layer is between 0.5 mm and 1 mm. The stabilizing layer is made of silicone oil material, and the thickness of the stabilizing layer is between 0.3 mm and 0.5 mm. The protective layer is made of high-temperature antioxidant oil material, and the thickness of the protective layer is between 0.2 and 0.3 mm. The structures of the first sealing film 81 and the second sealing film 82 are the same. The main function of the isolation layer is to prevent the dye 8 from contacting with air and to prevent the dye 8 from being oxidized or contaminated. Mineral oil has good sealing performance and can effectively isolate the entry of oxygen and moisture, thereby preventing the dye 8 from deteriorating due to oxidation. A thickness of 0.5 mm to 1 mm can ensure sufficient isolation efficiency and avoid changes in the properties of the dye 8 caused by long-term contact with air, especially for those dyes 8 that are prone to oxidation. A thicker isolation layer helps to improve the sealing effect but is not too thick to cause space waste. As a material for the stabilizing layer, silicone oil has excellent chemical stability and high-temperature stability. It can ensure that the chemical stability of the internal dye 8 is not affected when the external environment changes. Silicone oil can help maintain the environment inside the sealing film from being disturbed by external factors, especially changes in temperature and humidity. A thickness of 0.3 mm to 0.5 mm is appropriate, which can provide sufficient protection without being too thick to affect the flexibility of the film or increase the overall volume. The function of the protective layer is to prevent the dye 8 from undergoing an oxidation reaction when exposed to a high-temperature environment or oxygen. High-temperature antioxidant oil can prevent the dye 8 from decomposing or oxidizing under high-temperature conditions, ensuring the quality and service life of the dye 8. It can also prevent the dye 8 from contacting with external pollutants and provide additional physical protection. The thickness of the protective layer is relatively thin (0.2 mm to 0.3 mm) because its main function is to prevent high temperature and oxidation, and a thin layer can provide effective protection. An overly thick protective layer may make the overall film structure cumbersome, and not much protection thickness is required to achieve the antioxidant effect.

[0039] The stirring structure in this embodiment includes a first stirring blade 51 and a second stirring blade 52, the first stirring blade 51 is arranged at the lower end of the first partition block 71, and the second stirring blade 52 is arranged at the lower end of the second partition block 72. The first stirring blade 51 and the second stirring blade 52 are both connected to the storage chamber 15 for rotation, and a synchronous belt 511 is connected between the first stirring blade 51 and the second stirring blade 52. The first stirring blade 51 and the second stirring blade 52 are respectively arranged at the lower ends of the two partition blocks, and the stirring force can be effectively transmitted to different areas of the storage chamber 15. Since both are connected to the storage chamber 15 for rotation, the stirring blades can work simultaneously in the entire storage chamber 15, thereby ensuring uniform stirring of the material, avoiding the problem that the material in some areas is not stirred or stirred unevenly. The first stirring blade 51 and the second stirring blade 52 are connected by a synchronous belt 511, which enables the two to rotate in a synchronous manner. The synchronous belt 511 ensures that the rotation speed and movement direction of the two are consistent, thereby avoiding unbalanced movement or irregular stirring caused by the uncoordinated stirring blades. Synchronous stirring not only improves efficiency, but also reduces mechanical wear and vibration, and extends the service life of the equipment. Due to the design of the stirring blades and the action of the synchronous belt 511, the materials will not accumulate in the storage chamber 15 and can be stirred and mixed more evenly, thus avoiding the problem of dead corners or accumulation of materials in the storage chamber 15, ensuring the full mixing of the materials, and helping to improve the quality of subsequent processing.

[0040] The working process of this embodiment is as follows: first open the sealing cover 2, start the screw rod, so that the third partition block 31 and the fourth partition block 32 move away from each other, and the flannel cloth passes through the feed port 11, the first transport roller 61, the dyeing roller 63, the second transport roller 62, the first film pressing roller 91 and the second film pressing roller 92 and the drying chamber 16 in sequence, and finally flows out from the discharge port 12, and then start the screw rod in the reverse direction to make the third partition block 31 and the fourth partition block 32 move toward each other until they abut, and finally close the sealing cover 2, and the flannel cloth is transported and dyed by rotating the first transport roller 61 and the second transport roller 62.
