Description

Technical Field

[0001] This invention relates to the field of fabric technology, and in particular to a double-warp cotton-feel nylon plain weave fabric and its preparation process. Background Technology

[0002] While existing double-warp cotton-feel nylon plain weave fabrics offer a balance of strength and comfort, they suffer from weak antistatic properties, making them particularly unsuitable for use as workwear. Furthermore, during fabric winding, tension sensors or mechanical swing arms are typically used to detect the fabric edge position and then actively adjust the position of the fabric roll or guide rollers to keep the fabric centered during winding. This requires the fabric to have a certain tension or clear edges, making the fabric susceptible to damage from the mechanical devices. Additionally, the mechanical components used for detection are prone to wear and tear, making them unsuitable for long-term testing and use. Summary of the Invention

[0003] To address the technical problem of weak antistatic effect in existing double-warp cotton-feel nylon plain weave fabrics, this invention proposes a double-warp cotton-feel nylon plain weave fabric and its preparation process.

[0004] The present invention proposes a double-warp cotton-feel nylon plain weave fabric, comprising a base layer, wherein the base layer is woven from nylon yarn, cotton-feel yarn and conductive fibers, and both the upper and lower surfaces of the base layer are coated with a conductive coating.

[0005] Preferably, the conductive coating is made of a conductive polymer suspension.

[0006] The above technical solution utilizes a conductive polymer suspension to coat the fabric surface, thereby increasing the fabric's antistatic effect.

[0007] A preparation process for a double-warp cotton-feel nylon plain weave fabric, the preparation method is as follows: Step 1, prepare conductive fibers, treat the yarn with antistatic treatment, prepare a cationic antistatic agent solution with a concentration percentage of 1-2, soak the yarn for 16-20 minutes, and then dry it to make conductive fibers; Step two: Weave conductive fibers with nylon yarn and cotton-feel yarn in a ratio of 1:5:4; the base layer is then formed. Step 3: Prepare a conductive polymer suspension, coat the conductive polymer suspension onto the surface of the base layer, and then dry it at a temperature of 150-160 degrees Celsius for 50-60 seconds to produce the fabric. Step four: The prepared fabric is rolled up and the fabric is corrected by a correction device. Step 5: Randomly sample the fabric and conduct electrostatic performance testing, physical performance testing, and appearance inspection.

[0008] Preferably, the correction device includes a base, a correction mechanism is mounted on the upper surface of the base, the correction mechanism drives the fabric to shift horizontally; a drive mechanism is mounted on the upper surface of the base, the drive mechanism provides power for the operation of the correction mechanism.

[0009] Preferably, the correction mechanism includes a correction roller, the outer surface of which is rotatably connected to a conveying pipe. The outer surface of the conveying pipe is provided with traction grooves, and the inner wall of the traction grooves is provided with air holes. The end of the air holes communicates with the interior of the conveying pipe.

[0010] The above technical solution utilizes air holes inside the traction pattern to facilitate the blowing of air into the traction pattern, thereby facilitating the removal of impurities such as lint from the traction pattern.

[0011] Preferably, a guide pipe is fixedly connected to the inner bottom wall of the correction roller, and a drive seat is fixedly connected to both ends of the correction roller. The lower end of the drive seat is slidably connected to the upper surface of the base via a guide rail.

[0012] The above technical solution utilizes a guide pipe to direct airflow only to the lower end of the conveying pipe, thereby facilitating the directional cleaning of lint in the traction groove. A receiving bag can also be installed at the lower end of the conveying pipe to facilitate the directional collection of the cleaned lint.

[0013] Preferably, a power box is fixedly connected to the surface of the drive seat, an airbag is fixedly connected to the inner side wall of the power box, a pressure plate is fixedly connected to the outer surface of the airbag, and the interior of the airbag is connected to one end of the guide tube through an air pipe.

[0014] The above technical solution utilizes a pressure plate to pull one end of the airbag, thereby facilitating the control of airbag inflation and deflation through the movement of the pressure plate.

[0015] Preferably, the driving mechanism includes a drive motor, the upper surface of the base is fixedly connected to the lower end of the drive motor, the output shaft of the drive motor is connected to a lead screw through a reduction gearbox, a sleeve is threaded onto the outer surface of the lead screw, and the outer surface of the sleeve is fixedly connected to the lower end of the drive seat.

[0016] The above technical solution utilizes a drive motor to provide power for the movement of the drive base, thereby facilitating the control of the drive base's movement.

[0017] Preferably, the output shaft of the gearbox is driven by a power transmission mechanism. The inner wall of the power box is rotatably connected to a drive gear and a driven gear via a mounting plate. The upper end of the power transmission mechanism is driven by a rotating shaft to the drive gear. The two driven gears are located at the upper and lower ends of the drive gear, respectively. The surfaces of the two driven gears mesh with the surface of the drive gear through snap teeth. A non-circular gear is fixedly connected to the surface of the driven gear. A bidirectional rack is fixedly connected to the surface of the pressure plate via a fixing block. The bidirectional rack is located between the two non-circular gears.

[0018] The above technical solution utilizes the synchronous rotation of two irregular gears, which ensures that at most one irregular gear contacts the bidirectional rack during the operation of the drive gear.

[0019] Preferably, a detection transmission mechanism is fixedly inserted into one side surface of the power box. The lower end of the detection transmission mechanism is connected to the drive gear via a rotating shaft. A detection box is fixedly connected to the upper surface of the detection transmission mechanism. A detection gear is drivenly connected to the upper end of the detection transmission mechanism. The detection gear is located inside the detection box. A sliding groove is formed on the outer surface of the detection box. A detection plate is slidably connected to the inner wall of the sliding groove. A magnetoresistive sensor is fixedly connected to one end of the detection plate. The magnetoresistive sensor is located on the outer surface of the detection box. A detection rack is fixedly connected to the other end of the detection plate.

[0020] The above technical solution utilizes a magnetoresistive sensor to perform non-contact detection of fabric offset, avoiding wear between the equipment and the fabric. Both the power transmission mechanism and the detection transmission mechanism consist of a housing, a transmission belt, and two pulleys. The transmission belt and the two pulleys are located inside the housing, with the transmission belt sleeved on the surface of the two pulleys.

[0021] The beneficial effects of this invention are as follows: 1. By adding conductive fibers to the double-warp cotton-feel nylon plain weave fabric, the antistatic effect of the fabric is improved while maintaining the soft and skin-friendly feel of cotton, avoiding the stiffness and roughness of traditional conductive fabrics, and taking into account both functionality and comfort.

[0022] 2. The fabric is corrected during winding by setting up a correction mechanism. A magnetoresistive sensor is used instead of a traditional tension sensor. The magnetoresistive sensor detects the conductive fibers in the fabric, avoiding direct contact between the sensor and the fabric, thus avoiding wear and tear on the equipment and the fabric, and facilitating long-term use.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figures 1-8 A double-warp cotton-feel nylon plain weave fabric includes a base layer woven from nylon yarn, cotton-feel yarn and conductive fibers. The upper and lower surfaces of the base layer are coated with a conductive coating, which is made of a conductive polymer suspension. The conductive polymer suspension is applied to the fabric surface to increase the antistatic effect of the fabric.

[0027] A preparation process for a double-warp cotton-feel nylon plain weave fabric includes the following steps: Step 1: Prepare conductive fibers by treating the yarn with antistatic agents, preparing a cationic antistatic agent solution with a concentration of 1-2%, soaking the yarn for 16-20 minutes, and then drying it to produce conductive fibers; Step 2: Weave the conductive fibers with nylon yarn and cotton-feel yarn in a ratio of 1:5:4 to produce a base layer; Step 3: Prepare a conductive polymer suspension, coat the surface of the base layer with the conductive polymer suspension, and then dry it at a temperature of 150-160 degrees Celsius for 50-60 seconds to produce the fabric; Step 4: Roll up the prepared fabric and correct its deviation using a web-correcting device; Step 5: Randomly inspect the fabric and perform electrostatic performance testing, physical performance testing, and appearance inspection.

[0028] By adding conductive fibers to the double-warp cotton-feel nylon plain weave fabric, the antistatic effect of the fabric is improved while maintaining the soft and skin-friendly feel of cotton, avoiding the stiffness and roughness of traditional conductive fabrics, and taking into account both functionality and comfort.

[0029] To correct the fabric roll-up, a correction device is provided, including a base 1. A correction mechanism is mounted on the upper surface of the base 1, which drives the fabric to shift horizontally. A drive mechanism is mounted on the upper surface of the base 1, providing power for the operation of the correction mechanism. The correction mechanism includes a correction roller 2. A conveying pipe 21 is rotatably connected to the outer surface of the correction roller 2. The outer surface of the conveying pipe 21 has traction patterns, and the inner wall of the traction patterns has air holes. The ends of the air holes communicate with the interior of the conveying pipe 21. By opening air holes inside the traction patterns, it is easy to blow air into the traction patterns, thereby facilitating the discharge of impurities such as lint. A guide pipe 22 is fixedly connected to the inner bottom wall of the correction roller 2. Both ends of the correction roller 2 are... A drive base 23 is fixedly connected, and the lower end of the drive base 23 is slidably connected to the upper surface of the base 1 via a guide rail. The airflow is sent only to the lower end of the delivery pipe 21 by the guide pipe 22, which facilitates the directional cleaning of the lint in the traction groove. A receiving bag can also be installed at the lower end of the delivery pipe 21 to facilitate the directional collection of the cleaned lint. A power box 24 is fixedly connected to the surface of the drive base 23. An airbag 25 is fixedly connected to the inner wall of the power box 24. A pressure plate 26 is fixedly connected to the outer surface of the airbag 25. The interior of the airbag 25 is connected to one end of the guide pipe 22 through an air pipe. The pressure plate 26 is used to pull one end of the airbag 25, which facilitates the inflation and deflation of the airbag 25 by moving the pressure plate 26.

[0030] To drive the straightening roller 2, the drive mechanism includes a drive motor 3. The upper surface of the base 1 is fixedly connected to the lower end of the drive motor 3. The output shaft of the drive motor 3 is driven by a lead screw 31 through a reduction gearbox. A sleeve 32 is threaded onto the outer surface of the lead screw 31. The outer surface of the sleeve 32 is fixedly connected to the lower end of the drive seat 23. The drive motor 3 provides power for the movement of the drive seat 23, thereby facilitating the control of the movement of the drive seat 23. The output shaft of the reduction gearbox is driven by a power transmission mechanism 33. The inner wall of the power box 24 is rotatably connected to a drive gear 34 and a driven gear 35 through a mounting plate. 5. The upper end of the power transmission mechanism 33 is connected to the drive gear 34 via a rotating shaft. Two driven gears 35 are located at the upper and lower ends of the drive gear 34, respectively. The surfaces of the two driven gears 35 are engaged with the surfaces of the drive gear 34 via snap teeth. A special-shaped gear 36 is fixedly connected to the surface of the driven gear 35. A bidirectional rack 37 is fixedly connected to the surface of the pressure plate 26 via a fixing block. The bidirectional rack 37 is located between the two special-shaped gears 36. By utilizing the synchronous rotation of the two special-shaped gears 36, it is possible to ensure that at most one special-shaped gear 36 contacts the bidirectional rack 37 when the drive gear 34 is running.

[0031] To detect fabric offset, a detection transmission mechanism 38 is fixedly inserted into one side surface of the power box 24. The lower end of the detection transmission mechanism 38 is connected to the drive gear 34 via a rotating shaft. A detection box 39 is fixedly connected to the upper surface of the detection transmission mechanism 38, and a detection gear 310 is drivenly connected to the upper end of the detection transmission mechanism 38. The detection gear 310 is located inside the detection box 39. A sliding groove is formed on the outer surface of the detection box 39, and a detection plate 311 is slidably connected to the inner wall of the groove. A magnetoresistive sensor 312 is fixedly connected to one end of the detection plate 311. On the outer surface of the detection box 39, the other end of the detection plate 311 is fixedly connected to a detection rack 313. The surface of the detection rack 313 meshes with the surface of the detection gear 310 through a toothed engagement. The two detection racks 313 are located above and below the detection gear 310, respectively. The magnetoresistive sensor 312 is used to perform non-contact detection of the fabric offset, avoiding wear between the equipment and the fabric. The power transmission mechanism 33 and the detection transmission mechanism 38 are both composed of a housing, a transmission belt and two pulleys. The transmission belt and the two pulleys are located inside the housing, and the transmission belt is sleeved on the surface of the two pulleys.

[0032] By setting up a correction mechanism to correct the fabric during winding, a magnetoresistive sensor 312 is used instead of a traditional tension sensor to detect conductive fibers in the fabric. Direct contact between the sensor and the fabric is avoided, thus preventing wear and tear on the equipment and the fabric, and facilitating long-term use.

[0033] Working principle: In use, the fabric is fed into the correction device and slides on the surface of the conveying tube 21. The magnetoresistive sensor 312 detects the change in the magnetic field on one side of the fabric. When the fabric deviates, the magnetic field changes, and the drive motor 3 is started. The drive motor 3 drives the drive seat 23 to move through the lead screw 31 and the sleeve 32. The drive seat 23 drives the fabric to move back to the correct position through the conveying tube 21.

[0034] When the drive motor 3 is running, the drive gear 34 is driven to rotate through the power transmission mechanism 33. The drive gear 34 drives the irregular gear 36 to rotate through the driven gear 35. The two irregular gears 36 alternately push the bidirectional rack 37. The bidirectional rack body squeezes the airbag 25 through the pressure plate 26. The airbag 25 sprays air into the lower inner wall of the delivery pipe 21 through the guide pipe 22 and cleans out the lint in the traction groove on the surface of the delivery pipe 21.

[0035] Meanwhile, the irregular gear 36 drives the detection gear 310 to rotate through the detection transmission mechanism 38. The detection gear 310 drives the magnetoresistive sensor 312 on the surface of the detection plate 311 to translate through the detection rack 313, thereby adjusting the detection position and increasing the accuracy of the detection results.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
