A method for producing an antibacterial yarn

Abstract

This invention discloses a method for producing antibacterial yarn, relating to the field of antibacterial yarn production technology. Step one involves selecting high-quality fibers as raw materials, specifically cotton, polyester, and nylon; and preparing an antibacterial agent. Step two involves cleaning and removing impurities from the raw material fibers, ensuring their purity and quality through soaking and washing. When the support assembly vibrates up and down under the action of the drive assembly, the support rod, along with the piston plate, moves up and down within the end cylinder. When the piston plate moves downward, it blows air from the bottom of the end cylinder into the end box through the air blower and one-way valve, causing the antibacterial liquid in the end box to agitate, ensuring the uniformity of the antibacterial liquid. When the piston plate moves upward, it draws air out under the action of the air inlet pipe and one-way valve, repeating this process to continuously agitate the antibacterial liquid.

Description

Technical Field

[0001] This invention relates to the field of antibacterial yarn production technology, and in particular to a method for producing antibacterial yarn. Background Technology

[0002] Antimicrobial yarn is a type of yarn treated with antimicrobial agents, giving it the ability to inhibit the growth of bacteria, fungi, and other microorganisms. It is widely used in the textile industry to improve the hygiene and durability of products.

[0003] The main characteristics and advantages of antibacterial yarn include: Antibacterial properties: Antibacterial yarns typically contain antibacterial agents such as silver ions, copper ions, and zinc ions. These antibacterial agents can disrupt the cell structure of bacteria and other microorganisms, thereby inhibiting their growth and reproduction. Long-lasting properties: The antibacterial effect of antibacterial yarns usually lasts for a long time, providing durable antibacterial properties. Even after multiple washes, the antibacterial function is maintained. Hygiene properties: Antibacterial yarns effectively inhibit bacterial growth, reduce odor and contamination, and keep textiles clean and hygienic. By adding antibacterial agents, antibacterial yarns effectively inhibit the growth of bacteria and other microorganisms, and are widely used in medical, home textiles, clothing, and functional textiles, providing more hygienic and healthy products.

[0004] A search revealed Chinese patent CN108638596A, which discloses a production process for antibacterial composite fabric. This process solves the technical problems of existing composite fabrics lacking corresponding production methods, hindering rapid mass production, and resulting in slow production speeds. The production process includes the following steps: a) Making the outer layer: By weight percentage, 40-50% milk fiber, 30-40% Tencel fiber, and 10-20% wool fiber are blended and woven into fabric one; an antibacterial liquid is coated onto both surfaces of fabric one using a surface treatment device; the coated fabric one is the outer layer. b) Making the inner layer: By weight percentage, 40-60% acetate fiber, 20-30% Tencel fiber, and 10-20% polyester fiber are blended and woven into fabric two; the woven fabric two is the inner layer. c) Sewing: The outer layer is placed on top of the inner layer, and the two are sewn together using sewing equipment to obtain the antibacterial composite fabric.

[0005] However, the above invention has the following shortcomings: The above patent mainly uses the bottom plate to drive the antibacterial liquid in the soaking tank to vibrate, so that the antibacterial liquid and the fabric are mixed evenly. However, in actual use, since the yarn is relatively fixed, it can only promote the vibration and mixing of the antibacterial liquid to a certain extent, but its effect is limited and cannot achieve the ideal effect, so it has limitations.

Coaxially arranged limiting friction wheels are fixedly provided at both ends of the pay-off roller.

[0013] A drive assembly is disposed between the top of the base and the arched end.

[0014] Preferably, drive motors are fixedly installed on both outer walls of the U-shaped frame, and drive friction wheels are fixedly installed on the output shafts of the two drive motors. A receiving box is fixedly installed on the inner bottom of the U-shaped frame, and a drain port is opened on one side of the receiving box. A valved pipe is fixed inside the drain port.

[0015] Preferably, each pair of end cylinders is fixedly connected to an air inlet main pipe on one side, and a one-way air valve is fixed to one end of the air inlet main pipe. The output direction of the one-way air valve is from the one-way air valve to the end cylinder.

[0017] Preferably, both the take-up roller and the unwind roller have multiple winding grooves.

[0018] Preferably, a pair of side brackets are fixed on one side of both U-shaped frame one and U-shaped frame two, and a support rod end is fixedly connected between two adjacent side brackets. Multiple shafts are rotatably installed between the support rod ends, and multiple grooved wheels are fixed on the outer peripheral wall of each shaft.

[0019] Preferably, the drive assembly includes a dual-axis motor, which is fixed on the base. Both output shafts of the dual-axis motor are fixedly connected to extension shafts. Both ends of the top outer wall of the base are fixedly mounted with support rods, and the ends of the support rods are rotatably connected to the extension shafts.

[0036] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides an improved method for producing antibacterial yarn. The technical solution of this invention is as follows:

[0038] like Figures 1 to 7 As shown, this embodiment of the invention provides a method for producing antibacterial yarn, specifically including the following steps:

[0039] Step 1: Select high-quality fibers as raw materials, including cotton, polyester, and nylon; and prepare antibacterial agents.

[0040] Step 2: Clean and remove impurities from the raw material fibers by soaking and washing to ensure the purity and quality of the fibers;

[0041] Step 3: Add the antibacterial agent to the processing equipment to dissolve it, and mix the antibacterial agent liquid with the fiber to ensure that it is fully and evenly mixed;

[0042] Step 4: Spin the antibacterial treated fibers;

[0043] The processing equipment in step three includes a base 1, with an end box 2 fixed to the top outer wall of the base 1. An arched end 4 is located at the bottom centerline of the end box 2, and another arched end 4 is located at the bottom center of the end box 2. Support assemblies are located at both ends of the top outer wall of the base 1. Each support assembly includes a pair of end cylinders 24, and each end cylinder 24 has a prismatic structure. A piston plate 211 is slidably connected inside each end cylinder 24, and a vibration spring 29 is fixed between the top outer wall of the piston plate 211 and the top of the end cylinder 24. A support rod 21 is fixedly connected to the top of each pair of piston plates 211. U-shaped frame 11 and U-shaped frame 20 are fixedly installed at the top of the support rod 21, and both U-shaped frame 11 and U-shaped frame 20 have elongated grooves 16 at their tops. The tops of U-shaped frame 11 and U-shaped frame 20 are respectively connected to take-up roller 27 and pay-off roller 17 through the elongated grooves 16. Coaxial limiting friction wheels 19 are fixedly installed at both ends of pay-off roller 17. With the above structure, in actual use, pay-off roller 17 can release fibers and connect the other end of the fibers to take-up roller 27, so that the antibacterial liquid inside end box 2 can fully contact and mix with the fibers.

[0044] A drive assembly is disposed between the top of the base 1 and the arched end 4; the drive assembly is used to drive the support assembly to vibrate up and down, thereby improving the full contact between the fiber filaments and the antibacterial liquid.

[0045] Furthermore, drive motors 7 are fixedly installed on both outer walls of the U-shaped frame 11, and drive friction wheels 9 are fixedly installed on the output shafts of the two drive motors 7. A receiving box 10 is fixedly installed on the inner bottom of the U-shaped frame 11, and a drain port is opened on one side of the receiving box 10. A valve pipe 8 is fixed inside the drain port.

[0046] With the above structure, in actual operation, the drive motor 7 can drive the drive friction wheel 9 to rotate, and the limit friction wheel 19 at both ends of the take-up roller 27 can drive the take-up roller 27 to rotate and take up the yarn; at the same time, when the support component vibrates up and down, it can effectively drain the water from the take-up roller 27, thereby ensuring the dryness of the fiber yarn.

[0047] As a further embodiment of the present invention, an air inlet main pipe 6 is fixedly connected to one side of each pair of end cylinders 24, and a one-way air valve 5 is fixed to one end of the air inlet main pipe 6. The output direction of the one-way air valve 5 is from the one-way air valve 5 to the end cylinder 24.

[0048] Furthermore, each end cylinder 24 has a through hole 26 on the side near the end box 2, and each through hole 26 has an air pipe 3 fixed inside. The end of the air pipe 3 near the end cylinder 24 is fixed with a one-way air valve 25, and the output direction of the one-way air valve 25 is from the end cylinder 24 to the end box 2.

[0049] With the above structure, when the support assembly vibrates up and down under the action of the drive assembly, the support rod 21 together with the piston plate 211 can move up and down in the end cylinder 24. When the piston plate 211 moves down, the air at the bottom of the end cylinder 24 can be blown into the end box 2 through the air pipe 3 and the one-way air valve 25, thereby causing the antibacterial liquid in the end box 2 to turn over, so as to ensure the uniformity of the antibacterial liquid.

[0050] When the piston plate 211 moves upward, it can draw air under the action of the air inlet pipe 6 and the one-way air valve 5. This process is repeated to continuously agitate the antibacterial liquid.

[0051] Furthermore, both the take-up roller 27 and the unwind roller 17 are provided with multiple winding grooves 18; the winding grooves 18 can limit the fiber filaments to prevent them from deviating.

[0052] Furthermore, a pair of side brackets 15 are fixed on one side of both U-shaped frame 11 and U-shaped frame 20, and a support rod end 14 is fixedly connected between two adjacent side brackets 15. Multiple shafts 13 are rotatably installed between the support rod ends 14, and multiple grooved wheels 12 are fixed on the outer peripheral wall of each shaft 13. Through the above structure, the shaft 13 with multiple grooved wheels 12 can also limit the fiber thread.

[0053] As a further embodiment of the present invention, the drive assembly includes a dual-axis motor 28, which is fixed on the base 1. Both output shafts of the dual-axis motor 28 are fixedly connected to extension shafts 22. Both ends of the top outer wall of the base 1 are fixedly mounted with support rods, and the ends of the support rods are rotatably connected to the extension shafts 22. Cams 23 are fixed on the outer peripheral walls of one end of the two extension shafts 22, and arc-head abutment rods 30 are fixed on the top bottom side walls of the two support rods 21. With the above structure, when the processing equipment is running, the dual-axis motor 28 can be started and driven to rotate the two extension shafts 22 and the cams 23. When the cams 23 rotate, they can abut the arc-head abutment rods 30 above at a fixed frequency, thereby driving the support rods 21 to vibrate under the action of the vibration spring 29.

[0054] As a further embodiment of the present invention, a crossbeam is fixed between each two adjacent side brackets 15, and a folded rod 31 is fixed at the middle of the bottom side wall of each crossbeam. A slider 34 is rotatably mounted on the bottom end of each folded rod 31 via a movable shaft.

[0055] Furthermore, horizontal shafts 35 are fixedly installed on both sides of the end box 2 near the inner bottom, and a swing plate 32 is rotatably installed on the outer peripheral wall of each horizontal shaft 35.

[0056] Furthermore, the top outer walls of both swing plates 32 are provided with grooves 33, and the grooves 33 slide in cooperation with the slider 34.

[0057] With the above structure, when the support rod 21 moves up and down, it can drive the U-shaped frame 11 and the U-shaped frame 20 to move up and down, and drive the side bracket 15 to move up and down. This setting can promote the contact between the fiber thread and the antibacterial liquid. On the other hand, the side bracket 15 can also drive the crossbeam and the folded rod 31 to move up and down, and use the folded rod 31 to pull the swing plate 32 along the horizontal axis 35 by the slider 34. This setting can also promote the mixing of the antibacterial liquid itself, and at the same time, it can also promote the mixing between the antibacterial liquid and the fiber thread.

[0058] The specific working method is as follows: When in use, the feed roller 17 with the fiber thread wound on it is placed on the U-shaped frame 20, and the take-up roller 27 is placed on the U-shaped frame 11. At the same time, the fiber thread is pulled through the groove wheel 12 and fixed on the take-up roller 27. The drive motor 7 drives the drive friction wheel 9 to rotate, and the take-up roller 27 is rotated to take up the thread by the limiting friction wheels 19 at both ends of the take-up roller 27.

[0059] The dual-axis motor 28 is started and drives the two extended shafts 22 and the cam 23 to rotate. When the cam 23 rotates, it makes a fixed-frequency contact with the upper arc head abutment 30. Under the action of the vibration spring 29, the arc head abutment 30 drives the support rod 21 to vibrate.

[0060] When the support assembly vibrates up and down under the action of the drive assembly, the support rod 21, together with the piston plate 211, moves up and down in the end cylinder 24. When the piston plate 211 moves downward, the air at the bottom of the end cylinder 24 is blown into the end box 2 through the air pipe 3 and the one-way air valve 25, thereby agitating the antibacterial liquid in the end box 2 to ensure the uniformity of the antibacterial liquid. When the piston plate 211 moves upward, air is drawn out under the action of the air inlet pipe 6 and the one-way air valve 5. This process is repeated to continuously agitate the antibacterial liquid. When the support rod 21 moves up and down, it drives the U-shaped frame 11 and the U-shaped frame 211. The support assembly moves up and down, causing the side bracket 15 to move up and down as well. This arrangement promotes the contact between the fiber yarn and the antibacterial liquid. On the other hand, the side bracket 15 also causes the crossbeam and the folded rod 31 to move up and down. The folded rod 31, through the slider 34, pulls the swing plate 32 to swing along the horizontal axis 35. This arrangement also promotes the mixing of the antibacterial liquid itself and the mixing between the antibacterial liquid and the fiber yarn. At the same time, when the support assembly vibrates up and down, it effectively drains water from the take-up roller 27, thereby ensuring the dryness of the fiber yarn. The liquid generated by the draining can be collected by the receiving box 10.

[0061] The foregoing description enables those skilled in the art to make or use the present 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.
