Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a production process and equipment for a high-elasticity antibacterial knitted fabric. Background Technology

[0002] The core advantage of high-elasticity antibacterial knitted fabric lies in its perfect combination of unparalleled wearing comfort, freedom of movement, and proactive hygiene protection. It not only improves the physical properties and wearing experience of clothing, but more importantly, it improves the hygiene environment that is closely related to human health through technological means, meeting the higher pursuit of modern consumers for functionality, comfort, and a healthy lifestyle.

[0003] Mercerizing is a production process for knitted fabrics. Its core involves immersing the fabric in a high-concentration caustic soda solution under low tension. The cotton fibers swell violently under the influence of concentrated alkali. However, during this process, tension is needed to constrain the knitted fabric to prevent excessive shrinkage. Subsequently, a stretching process is required to mechanically pull the shrunken fabric back to the required width and unit length (gram weight per meter) and fix it in place. However, in actual production, the fibers of the knitted fabric are easily damaged during stretching, resulting in significant loss of elasticity and a stiffer hand feel. To address this issue, this invention proposes a production process and equipment for a high-elasticity antibacterial knitted fabric. Summary of the Invention

[0004] To achieve the above objectives, the present invention specifically adopts the following technical solution: A production process for a high-elasticity antibacterial knitted fabric includes the following steps: S1: Core-spun yarn knitting: using spandex filament as the core yarn and wrapping it with cotton / polyester blended yarn for knitting; S2: Pretreatment: Treat in an alkaline-oxygen bath at 90-95℃ for 20-30 minutes; S3: Integrated mercerizing and stretching treatment: Immerse the fabric in a caustic soda solution with a concentration of 220-250g / L, and simultaneously start the bidirectional stretching device to apply intermittent warp and weft elastic expansion to the fabric. S4: Mechanical stretching and resetting: The neutralized wet fabric is fed into a continuous tenter frame and mechanically stretched without heating to expand the width to 102-105% of the target width, while controlling the longitudinal overfeed by 1-3%; S5: Neutralize with water wash: neutralize with acetic acid solution at 40-50℃ to pH=6.5-7.0; S6: Antibacterial treatment: Impregnated with an aqueous polyurethane finishing liquid containing nano-silver / zinc ions, with a liquid retention rate of 70-80%; S7: Microwave-assisted drying: Treat in a 5-10kW microwave field for 90-120 seconds; S8: Hot air setting: Set the shape with hot air at 160-180℃ for 30 seconds to lock in the final size.

[0005] A production device for high-elasticity antibacterial knitted fabric, applied to the production process of the aforementioned high-elasticity antibacterial knitted fabric, includes: A mercerizing trough, in which a conveyor roller is rotatably mounted; Two extrusion rollers are rotatably engaged with a mercerizing trough, and meshing spur gears are installed at their ends; Two eccentric rollers are rotatably installed in the mercerizing trough. The conveying roller, eccentric roller and extrusion roller are sequentially connected by a pulley assembly. Both ends of the eccentric roller are slidably fitted with cylindrical sleeves. The eccentric roller is equipped with a power unit to drive the two cylindrical sleeves to move synchronously in opposite directions.

[0006] Furthermore, the power unit includes a slider constructed inside the cylindrical sleeve, the eccentric roller having a groove that slides in cooperation with the slider, a movable rod rotatably mounted inside the eccentric roller, the movable rod having symmetrically formed oblique annular grooves on its outer side, the slider having a guide post constructed on it, and a roller being sleeved on its outer side, the roller being tangentially rolled to the inner side of the oblique annular groove, and the eccentric roller having a drive mechanism for driving the movable rod to rotate.

[0007] Furthermore, the driving mechanism includes a rotating rod coaxially passing through the eccentric roller shaft, a first gear mounted on the movable rod, a second gear meshing with the rotating rod, a first helical gear mounted on the eccentric roller shaft, a second helical gear connected to the end of the rotating rod, a mounting block constructed on the outside of the silkening groove, a third helical gear rotatably mounted on the mounting block, and both the first and second helical gears meshing with the third helical gear.

[0008] Furthermore, a seal is installed on the eccentric roller, which covers the groove and slides against the inner side of the cylindrical sleeve.

[0009] Furthermore, the sealing element includes a rubber ring, and two annular grooves are opened on the outer side of the eccentric roller. Two sliding grooves are respectively located in the two annular grooves. The rubber rings are symmetrically arranged on both sides of the sliding grooves and connected to the annular grooves. Conical sleeves are connected to the opposite sides of the rubber rings. The conical sleeves slide and overlap with the inner side of the cylindrical sleeves. A pressure boosting element is provided on the rotating rod, which is used to increase the air pressure inside the eccentric roller.

[0010] Furthermore, the inner side of the cylindrical sleeve is coated with a Teflon coating.

[0011] Furthermore, the pressurizing component includes an air groove coaxially formed at the end of the rotating rod, the air groove being connected to the interior of the eccentric roller through a connecting hole, an air storage tank being mounted on the mounting block, a cavity being constructed on the second helical gear for connecting the air storage tank and the air groove, a solenoid valve being mounted on the air storage tank, and a pressure gauge being mounted on the second helical gear and electrically connected to the solenoid valve.

[0012] Furthermore, a set of annular blocks are linearly distributed on the cylindrical sleeve. Each annular block has a right-angled surface and an inclined surface on its two sides. The right-angled surface is located on the opposite sides of the two sets of annular blocks and is perpendicular to the axis of the cylindrical sleeve.

[0013] Furthermore, both sides of the two eccentric rollers are provided with inclined plates, which are connected to the inner wall of the mercerizing groove and form an installation cavity, in which an ultrasonic generator is installed.

[0014] The beneficial effects of this invention are as follows: This invention intervenes in the shrinkage process of knitted fabric by using a bidirectional stretching device when the knitted fabric first begins to shrink, so as to perform intermittent and multiple stretches on the knitted fabric. By repeatedly stretching and relaxing the knitted fabric, the shrinkage of the knitted fabric is controlled within a small range, and some structures are maintained, so that the knitted fabric does not shrink excessively. This can effectively reduce fiber damage when the knitted fabric is mechanically stretched and reset at the end, making it more elastic and softer to the touch.

[0015] This invention employs a design that combines an eccentric roller and a cylindrical sleeve. When processing knitted fabrics, the eccentric roller gently pulls the fabric to prevent excessive shrinkage. Then, by rotating the eccentric roller in conjunction with the sliding cylindrical sleeve, a gap stretching design is used to promptly limit excessive shrinkage of the knitted fabric, controlling its shrinkage rate within a reasonable range (e.g., 5%-10%). This avoids excessive fiber compaction in the knitted fabric, ensuring that the fibers are in a more plastic state during subsequent swelling and stretching, significantly reducing the risk of strength loss.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] An embodiment of the present invention discloses a production process for a high-elasticity antibacterial knitted fabric, comprising the following steps: S1: Core-spun yarn knitting: using spandex filament as the core yarn and wrapping it with cotton / polyester blended yarn for knitting; S2: Pretreatment: Treat in an alkaline-oxygen bath at 90-95℃ for 20-30 minutes; S3: Integrated mercerizing and stretching treatment: Immerse the fabric in a caustic soda solution with a concentration of 220-250g / L, and simultaneously start the bidirectional stretching device to apply intermittent warp and weft elastic expansion to the fabric. S4: Mechanical stretching and resetting: The neutralized wet fabric is fed into a continuous tenter frame and mechanically stretched without heating to expand the width to 102-105% of the target width, while controlling the longitudinal overfeed by 1-3%; S5: Neutralize with water wash: neutralize with acetic acid solution at 40-50℃ to pH=6.5-7.0; S6: Antibacterial treatment: Impregnated with an aqueous polyurethane finishing liquid containing nano-silver / zinc ions, with a liquid retention rate of 70-80%; S7: Microwave-assisted drying: Treat in a 5-10kW microwave field for 90-120 seconds; S8: Hot air setting: Set the shape with hot air at 160-180℃ for 30 seconds to lock in the final size; This invention intervenes in the shrinkage process of knitted fabric by using a bidirectional stretching device when the knitted fabric first begins to shrink, so as to perform intermittent and multiple stretches on the knitted fabric. By repeatedly stretching and relaxing the knitted fabric, the shrinkage of the knitted fabric is controlled within a small range, and some structures are maintained, so that the knitted fabric does not shrink excessively. This can effectively reduce fiber damage when the knitted fabric is mechanically stretched and reset at the end, making it more elastic and softer to the touch.

[0020] like Figures 1-8 As shown, an embodiment of the present invention provides a production equipment for a high-elasticity antibacterial knitted fabric, applied to the production process of the aforementioned high-elasticity antibacterial knitted fabric, comprising: Mercerizing tank 1 contains caustic soda solution, and a conveying roller 2 is rotatably installed inside it. The conveying roller 2 is driven to rotate by motor 16. Two extrusion rollers 3 are rotatably engaged with mercerizing groove 1. The two extrusion rollers 3 are far apart from conveying roller 2, and their ends are equipped with meshing spur gears 4. Two eccentric rollers 5 are rotatably mounted in the mercerizing trough 1. The two eccentric rollers 5 are located between the conveyor roller 2 and the extrusion roller 3, and are situated within the caustic soda solution. The conveyor roller 2, eccentric roller 5, and extrusion roller 3 are sequentially connected via a pulley assembly 6. The pulley assembly 6 includes a drive wheel 601 connected to the shafts of the three rollers. Adjacent pulleys are connected via belts 602. The knitted fabric is sequentially wound around the conveyor roller 2, eccentric roller 5, and extrusion roller 3. When the motor 16 operates, it drives the conveyor roller 2, eccentric roller 5, and extrusion roller 3 to rotate synchronously. When the eccentric part of the eccentric roller 5 rotates below the axis, the eccentric roller 5 abuts against the top of the knitted fabric, thus slightly stretching the shrunken knitted fabric in the length direction. When the eccentric roller 5 rotates above the axis, the eccentric roller 5 gradually disengages from the top of the knitted fabric, thereby releasing the abutment. The fabric can shrink under the action of caustic soda solution. Under the action of two spur gears 4, two extrusion rollers 3 rotate relative to each other, thereby squeezing out the caustic soda solution from the knitted fabric. Both ends of the eccentric roller 5 are slidably fitted with cylindrical sleeves 7. The eccentric roller 5 is equipped with a power unit 8 to drive the two cylindrical sleeves 7 to move synchronously in opposite directions. When the eccentric part of the eccentric roller 5 rotates downward toward the axis, the two cylindrical sleeves 7 slide synchronously in opposite directions under the action of the power unit 8. Under the action of the frictional force generated by the contact between the top of the knitted fabric and the cylindrical sleeves 7, the knitted fabric can be stretched slightly in the width direction as the two cylindrical sleeves 7 move. When the eccentric part of the eccentric roller 5 rotates upward toward the axis, the two cylindrical sleeves 7 slide synchronously relative to each other under the drive of the power unit 8. At this time, the two cylindrical sleeves 7 on the eccentric roller 5 separate from the knitted fabric, and the knitted fabric can shrink. This invention employs a design that combines an eccentric roller 5 and a cylindrical sleeve 7. When processing knitted fabrics, the eccentric roller 5 gently pulls the fabric to prevent excessive shrinkage. Then, by rotating the eccentric roller 5 in conjunction with the sliding cylindrical sleeve 7, a gap stretching design is used to promptly limit excessive shrinkage of the knitted fabric, controlling its shrinkage rate within a reasonable range (e.g., 5%-10%). This avoids excessive fiber compaction in the knitted fabric, ensuring that the fibers are in a more plastic state during subsequent swelling and stretching, significantly reducing the risk of strength loss.

[0021] like Figures 3-8As shown, a further technical solution of the present invention is disclosed. The power unit 8 includes a slider 801 constructed inside the cylindrical sleeve 7. An eccentric roller 5 is provided with a sliding groove 802 and is slidably engaged with the slider 801. A movable rod 803 is rotatably mounted inside the eccentric roller 5. The movable rod 803 is parallel to the eccentric roller 5. A symmetrical oblique annular groove 804 is formed on the outer side of the movable rod 803. A guide post 805 is constructed on the slider 801. The guide post 805 is inserted into the oblique annular groove 804, and a roller 806 is sleeved on its outer side. The roller 806 is tangentially rolled with the inner side of the oblique annular groove 804. A drive mechanism 807 is provided on the eccentric roller 5. The movable rod 803 is used to drive the rotation of the movable rod 803. When the eccentric part of the eccentric roller 5 rotates to above the axis, the opposite ends of the two inclined ring grooves 804 on the movable rod 803 are close to the sliding groove 802. When the eccentric part of the eccentric roller 5 rotates to below the axis, the opposite ends of the two inclined ring grooves 804 on the movable rod 803 are close to the sliding groove 802. By adopting the above design, when the movable rod 803 is driven to rotate, the two guide posts 805 can be forced to drive the slider 801 to slide in opposite directions in the two sliding grooves 802 due to the contact between the inner walls of the two inclined ring grooves 804. In this way, the two cylindrical sleeves 7 can be linked together.

[0022] like Figure 1 , Figure 5 and Figure 6 The specific structure of the drive mechanism 807 in this invention is disclosed. The drive mechanism 807 includes a rotating rod 8071 coaxially passing through the rotating shaft of the eccentric roller 5. The rotating rod 8071 is coaxial with the rotating shaft of the eccentric roller 5. A first gear 8072 is mounted on the movable rod 803, and a second gear 8073 meshing with it is mounted on the rotating rod 8071. When the rotating rod 8071 rotates, the movable rod 803 can be driven to rotate synchronously through the second gear 8073 and the first gear 8072. A first helical gear 8074 is mounted on the rotating shaft of the eccentric roller 5, and a second helical gear 8074 is connected to the end of the rotating rod 8071. 075, the outer side of the mercerizing groove 1 has a mounting block 8076, on which a third helical gear 8077 is rotatably mounted. The first helical gear 8074 and the second helical gear 8075 are both meshed with the third helical gear 8077. That is, when the eccentric roller 5 drives the first helical gear 8074 to rotate, it can drive the third helical gear 8077 to drive the second helical gear 8075 to rotate, thereby driving the rotating rod 8071 to rotate synchronously. By adopting the cooperative design of the first helical gear 8074, the second helical gear 8075 and the third helical gear 8077, the eccentric roller 5 and the movable rod 803 can be linked.

[0023] like Figures 6-8As shown, a further technical solution of the present invention is disclosed. A sealing element 9 is installed on the eccentric roller 5, which covers the slide groove 802 and slides and overlaps with the inner side of the cylindrical sleeve 7. It should be specifically noted that no matter where the slider 801 moves to the slide groove 802, the cylindrical sleeve 7 covers the opening of the slide groove 802. By adopting the design of the sealing element 9, the opening of the slide groove 802 is dynamically sealed in conjunction with the shell of the cylindrical sleeve 7, so that the caustic soda solution is not easy to enter the interior of the eccentric roller 5 through the opening of the slide groove 802.

[0024] like Figures 6-8 The specific structure of the sealing element 9 in this invention is disclosed. The sealing element 9 includes four rubber rings 901. Two annular grooves 902 are formed on the outer side of the eccentric roller 5. Two sliding grooves 802 are respectively located in the two annular grooves 902. The rubber rings 901 are symmetrically arranged on both sides of the sliding grooves 802 and connected to the annular grooves 902. The two rubber rings 901 are respectively connected to the inner walls of both sides of the annular grooves 902. Conical sleeves 903 are connected to the opposite sides of the rubber rings 901. With the larger outer diameter end of 903 facing each other, the tapered sleeve 903 slides and overlaps with the inner side of the cylindrical sleeve 7. The rotating rod 8071 is equipped with a pressure booster 904, which is used to increase the air pressure inside the eccentric roller 5. When the tapered sleeve 903 experiences sliding wear, the air entering the tapered sleeve 903, under the action of atmospheric pressure, can push the tapered sleeve 903 against the inner wall of the cylindrical sleeve 7, thereby compensating for the wear of the tapered sleeve 903 and keeping it in close contact with the inner wall of the cylindrical sleeve 7, thus maintaining good sealing performance for a long time. It should be specifically noted here that during the processing of knitted fabric, the movement speed is relatively slow. In other words, the rotation speed of the eccentric roller 5 and the sliding speed of the cylindrical sleeve 7 are also relatively slow. This effectively reduces the impact of the sliding friction resistance generated when the cylindrical sleeve 7 slides on the rubber sleeve, making it less likely for the rubber sleeve to fold.

[0025] like Figure 8 As shown, a further technical solution of the present invention is disclosed: the inner side of the cylindrical sleeve 7 is coated with a Teflon coating. The Teflon coating has alkali resistance and friction resistance, and can also enhance the smoothness of the inner side of the cylindrical sleeve 7, so that the cylindrical sleeve 7 and the conical sleeve 903 are less prone to sliding wear.

[0026] like Figure 1 , Figure 2 and Figure 6The specific structure of the pressurizing component 904 in this invention is disclosed. The pressurizing component 904 includes an air groove 9041 coaxially formed at the end of the rotating rod 8071. The air groove 9041 communicates with the interior of the eccentric roller 5 through a connecting hole 9042, which penetrates the outside of the rotating rod 8071. An air storage tank 9043 is mounted on the mounting block 8076, and the air storage tank 9043 stores compressed air. A cavity 9044 is constructed on the second helical gear 8075 to connect the air storage tank 9043 and the air groove 9041. A solenoid valve 9045 is mounted on the air storage tank 9043. After the solenoid valve 9045 is opened, the air storage tank... The gas inside 9043 can pass sequentially through cavity 9044, air groove 9041 and connecting hole 9042, and enter the eccentric roller 5. A pressure gauge 9046 is installed on the second helical gear 8075 and is electrically connected to the solenoid valve 9045. The pressure gauge 9046 can detect the internal air pressure of the eccentric roller 5. When the cylindrical sleeve 7 moves and the conical sleeve 903 wears, a small amount of gas inside the eccentric roller 5 will leak. When the internal air pressure of the eccentric roller 5 decreases, a signal can be sent and the solenoid valve 9045 can be opened to inject the gas stored in the air tank 9043 into the eccentric roller 5 so that the internal air pressure of the eccentric roller 5 is not easily reduced.

[0027] like Figures 5-7 As shown, a further technical solution of the present invention is disclosed. A set of annular blocks 10 are linearly distributed on the cylindrical sleeve 7. Right-angled surfaces 11 and inclined surfaces 12 are respectively constructed on both sides of the annular blocks 10. The right-angled surfaces 11 are located on the opposite sides of the two sets of annular blocks 10 and are perpendicular to the axis of the cylindrical sleeve 7. When the two cylindrical sleeves 7 are in contact with the top of the knitted fabric and slide in opposite directions, this design can increase the sliding resistance between the cylindrical sleeve 7 and the knitted fabric, so that the knitted fabric is not easy to slide on the cylindrical sleeve 7 during its movement.

[0028] like Figure 3 As shown, a further technical solution of the present invention is disclosed. Both sides of the two eccentric rollers 5 are provided with inclined plates 13. The inclined plates 13 are connected to the inner wall of the mercerizing trough 1 and form an installation cavity 14. The inclined plates 13 and the installation cavity 14 occupy the internal space of the mercerizing trough 1, which can reduce the amount of caustic soda solution. An ultrasonic generator 15 is installed in the installation cavity 14. The ultrasonic generator 15 can promote the penetration of alkali solution into the knitted fabric fibers and improve processing efficiency.

[0029] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
