Description

Technical Field

[0001] The invention belongs to the technical field of antibacterial fabric preparation, and specifically relates to an antibacterial fabric and a preparation process thereof. Background Art

[0002] Antibacterial fabrics can be used to make clothing and bedding, etc. During the preparation of the antibacterial fabrics, the pretreated fabrics are immersed in an antibacterial solution so that the antibacterial solution is adsorbed on the surface of the fabric, thereby achieving an antibacterial effect. During the use of the impregnation equipment, the antibacterial solution inside it may sink to the bottom due to poor fluidity, and thus cannot be evenly adsorbed on the surface of the fabric. In addition, during the impregnation process, the fabrics may be relatively loose and cannot be evenly adsorbed with the antibacterial solution. In the prior art, a conveyor wheel is used to tighten the fabric so that the fabric can be opened, but this completely limits the fabric and is inconvenient to remove, making it inconvenient to impregnate a small amount of fabric at a time.

[0051]

[0052] It can be seen from the above table that the added silver ion chitosan quaternary ammonium salt and plant antibacterial agent have good antibacterial effects, among which the antibacterial effects of silver ion chitosan quaternary ammonium salt and plant antibacterial agent are the main antibacterial components.

[0053] like Figures 1 to 6 As shown, the embodiment of the present invention provides a process for preparing an antibacterial fabric, comprising the following steps:

[0054] S1. Pretreatment: Polyester fiber and flax fiber are mixed to make warp, modal fiber and bamboo fiber are mixed to make weft, double-layer twill weave is used as the weave structure, and the blended fabric is made. Then the fabric is cleaned to remove oil and impurities to ensure the subsequent treatment effect;

[0055] S2. Impregnation: Powder the silver ion chitosan quaternary ammonium salt and dissolve it in water, then add nisin and sodium benzoate, and finally add sodium alginate, mix and dissolve them fully to make an antibacterial solution, transport the antibacterial solution to the impregnation equipment, and then soak the fabric in the antibacterial solution for a certain period of time to allow the silver ions to be adsorbed on the surface of the fabric;

[0056] S3. Silver ion finishing: preheat the oven to 150°C, then lay the fabric impregnated in step S2 on the rack in the oven for heat treatment. During the heat treatment, the temperature error is monitored to be no less than 20°C. After the heat treatment is completed, the temperature in the oven with light is naturally cooled before taking out the fabric;

[0057] S4. Post-treatment: Soften and waterproof the fabric to improve its performance;

[0058] S5. Inspection: Test the antibacterial effect and other performance indicators of the finished product to ensure compliance with the standards.

[0059] The impregnation equipment in the above-mentioned S2 impregnation includes an impregnation bin 1, a support frame 2 is fixedly connected to the rear side of the impregnation bin 1, a threaded rod 4 is movably connected to the inner cavity of the support frame 2, a movable ring 5 is meshed on the surface of the threaded rod 4, a bent connecting rod 6 is fixedly connected to the front side of the movable ring 5, a supporting plate 7 is fixedly connected to the bottom end of the bent connecting rod 6, a spring assembly 8 is fixedly connected to the inner cavity of the supporting plate 7, a moving frame 9 is fixedly connected to the side of the spring assembly 8 away from the supporting plate 7, a ramp block 10 is fixedly connected to the rear side of the moving frame 9, a moving frame 11 is fixedly connected to the side of the moving frame 9 away from the spring assembly 8, an extrusion wheel 13 is movably sleeved in the inner cavity of the moving frame 11, and a fixed frame 14 is fixedly connected to the side of the supporting plate 7 close to the moving frame 9.

[0060] The working principle and beneficial effects of the above technical solution are as follows: by delivering the antibacterial solution to the inner cavity of the impregnation bin 1, and at this time the carrying plate 7 is located above the impregnation bin 1 and the inclined surface block 10 is in contact with the second limiting rod 33, the limiting rod 33 limits the inclined surface block 10, so that the movable frame 9 is located in the inner cavity of the carrying plate 7, thereby separating the extrusion wheel 13 from the fixed frame 14, and then the fabric is wrapped around the outer surface of the carrying plate 7 for multiple turns and is located between the extrusion wheel 13 and the fixed frame 14, and then the servo motor 13 is started to drive the threaded rod 4 to rotate, and the rotation of the threaded rod 4 drives the carrying plate 7 at the bottom end of the curved connecting rod 6 to descend, thereby separating the second limiting rod 33 from the inclined surface block 10, and at this time, the movable frame 9 is driven to move by the tension of the spring assembly 8, thereby driving the extrusion wheel 13 to move toward the direction of the fixed frame 14, thereby clamping and fixing the fabric by the extrusion wheel 13 and the fixed frame 14, and squeezing the fabric by the extrusion wheel 13, so that the fabric is in a tight and open state;

[0061] When the supporting plate 7 is located in the inner cavity of the impregnation bin 1, the servo motor 3 is started to drive the threaded rod 4 to rotate, drive the moving ring 5 to move, and then drive the supporting plate 7 at the bottom end of the curved connecting rod 6 to move up and down, thereby realizing the up and down shaking of the fabric by the supporting plate 7, so that the antibacterial solution can fully contact the fabric and adsorb it, and the up and down shaking of the supporting plate 7 drives the antibacterial solution in the inner cavity of the impregnation bin 1 to shake, so that it remains active, and the antibacterial components in the antibacterial solution can be evenly and comprehensively attached to the surface of the fabric.

[0062] like Figure 5 As shown, in one embodiment, a piston cylinder 16 is fixedly connected to the bottom end of the support frame 2, a return spring 17 is fixedly connected to the inner cavity of the piston cylinder 16, a piston rod 18 is fixedly connected to the top of the return spring 17, a one-way air inlet valve 19 and a one-way air outlet valve 20 are fixedly connected to the bottom end of the piston cylinder 16, a compression cylinder 21 is fixedly connected to the bottom end of the one-way air outlet valve 20, an extrusion spring 22 is fixedly connected to the inner cavity of the compression cylinder 21, a compression plate 23 is fixedly connected to the side of the extrusion spring 22 close to the one-way air outlet valve 20, a delivery pipe 24 is fixedly connected to the side of the extrusion spring 22 close to the one-way air outlet valve 20, a switch pipe 25 is fixedly connected to the middle of the delivery pipe 24, a limit spring 26 is fixedly connected to the inner cavity of the switch pipe 25, a closing block 27 is fixedly connected to the side of the limit spring 26 close to the threaded rod 4, a triangular block 28 is fixedly connected to the side of the closing block 27 close to the threaded rod 4, and a driving wheel 34 is movably connected to the rear side of the switch pipe 25;

[0063] The working principle and beneficial effects of the above technical solution are as follows: by pressing the piston rod 18 when the movable ring 5 moves up and down, and then through the tension of the return spring 17, the piston rod 18 can draw external air into the inner cavity of the piston cylinder 16 when it moves upward in the inner cavity of the piston cylinder 16, and when the movable ring 5 drives the piston rod 18 to move downward, the air in the inner cavity of the piston cylinder 16 is squeezed into the inner cavity of the compression cylinder 21 through the one-way air outlet valve 20, and then the compression plate 23 is driven by the tension of the extrusion spring 22 to squeeze and compress the air in the inner cavity of the compression cylinder 21.

[0064] like Figure 2 As shown, in one embodiment, the top end of the delivery pipe 24 is fixedly connected to a heating chamber 29, the inner cavity of the heating chamber 29 is fixedly connected to a heating plate 30, and the bottom end of the heating chamber 29 is fixedly connected to a gas outlet 31;

[0065] The working principle and beneficial effects of the above technical solution are as follows: after the fabric in the inner cavity of the impregnation bin 1 is impregnated, the servo motor 3 is started to drive the moving ring 5 to move upward, thereby driving the carrying plate 7 to move upward from the inner cavity of the impregnation bin 1. At this time, the moving ring 5 drives the driving wheel 34 to contact the triangular block 28 and squeeze the triangular block 28, thereby squeezing the triangular block 28 in the direction of the closing block 27, and then the closing block 27 leaves the connection between the switch tube 25 and the conveying tube 24, so that the air in the inner cavity of the compression cylinder 21 is transported along the conveying tube 24 to the inner cavity of the heating bin 29, and then the air is heated by the heating bin 29. Due to the squeezing of the squeezing spring 22, the air flow rate is faster, and the air with a faster flow rate is blown out from the air outlet 31 to the surface of the fabric, thereby drying the fabric, thereby preventing the antibacterial solution on the fabric from dripping on other locations, thereby affecting the sanitary environment of other places.

[0066] like Figure 3 As shown, in one embodiment, a servo motor 12 is fixedly connected to the front side of the moving frame 11, an extrusion wheel 13 is fixedly sleeved on the output shaft of the servo motor 12, a limit rod 32 is fixedly connected to the top of the impregnation bin 1, and a triangular block 35 is fixedly connected to the side of the inclined block 10 close to the curved connecting rod 6;

[0067] The working principle and beneficial effects of the above technical solution are as follows: when the fabric is driven to rise by the carrying plate 7, the triangular block 2 35 contacts the limiting rod 1 32, and the limiting rod 1 32 squeezes the triangular block 2 35, driving the inclined block 10 to move, and then the inclined block 10 drives the moving frame 9 to move a distance toward the fixed frame 14 again, so that the squeezing wheel 13 moves toward the fixed frame 14, and the squeezing wheel 13 squeezes the fabric with greater force to deform it;

[0068] Then, the servo motor 12 is started to drive the extrusion wheel 13 to rotate, so that the fabric on the surface of the carrier plate 7 rolls. At this time, an external receiving device is used to receive and fix one end of the fabric. Then, through the rotation of the extrusion wheel 13, all the fabrics are slowly transported to the outside through the extrusion wheel 13 and the fixed frame 14. At this time, the air outlet head 31 blows hot air to the surface of the fabric, and the extrusion wheel 13 extrudes the fabric through the extrusion deformation, so that the antibacterial solution inside the fabric is quickly squeezed out, thereby realizing the ability to quickly dry the fabric and collect and recycle the antibacterial solution.

[0069] like Figure 2 As shown, in one embodiment, the top end of the limiting rod 1 32 is fixedly connected to the limiting rod 2 33, the limiting rod 2 33 is located in the action path of the inclined block 10, and the bottom end of the immersion bin 1 is fixedly connected to the control pump 36;

[0070] The working principle and beneficial effects of the above technical solution are as follows: after the fabric is completely unloaded, the threaded rod 4 rotates and continuously drives the supporting plate 7 to rise. At this time, the inclined block 10 contacts the limiting rod 33, and the inclined surface of the inclined block 10 contacts the limiting rod 33, so that the inclined block 10 moves toward the center of the supporting plate 7, thereby increasing the distance between the extrusion wheel 13 and the fixed frame 14, thereby facilitating the staff to load the material next time, and after the antibacterial solution in the inner cavity of the immersion bin 1 has been used multiple times, it can be discharged by starting the control pump 36.

[0071] like Figure 3 As shown, in one embodiment, a waterproof compartment is fixedly connected to the front side of the moving frame 11, a servo motor 2 12 is located in the inner cavity of the waterproof compartment, and a spring assembly 8 is composed of a damping telescopic rod and a spring, and the damping telescopic rod is located at the center of the spring inner cavity;

[0072] The working principle and beneficial effects of the above technical solution are as follows: by setting up a waterproof compartment, the waterproof compartment can protect the servo motor 12 to prevent the servo motor 12 from being damaged by water, and then the spring assembly 8 is composed of a damping telescopic rod and a spring, and the tension of the spring drives the movable frame 9 to extend out of the inner cavity of the supporting plate 7, and then the damping telescopic rod is set up to position and guide the movable frame 11 to prevent it from being offset during movement.

[0073] like Figure 5 As shown, in one embodiment, the top end of the piston rod 18 is fixedly connected with a contact plate, the bottom end of the moving ring 5 contacts the contact plate, the piston cylinder 16 is connected with the inner cavity of the compression cylinder 21 through the one-way air outlet valve 20, and the compression plate 23 is in contact with the inner wall of the compression cylinder 21;

[0074] The working principle and beneficial effects of the above technical solution are as follows: when the supporting plate 7 is driven by the movable ring 5 to move up and down in the inner cavity of the support frame 2, the piston rod 18 is pressed, and then the air in the inner cavity of the piston cylinder 16 is squeezed to the inner cavity of the compression cylinder 21 through the one-way air outlet valve 20, and then the compression plate 23 is driven by the extrusion spring 22 to compress the air in the inner cavity of the compression cylinder 21, so that the inner cavity of the compression cylinder 21 has a higher air pressure when it is discharged.

[0075] like Figure 3 As shown, in one embodiment, the inner cavity of the support frame 2 is fixedly connected with a guide rod 15, the moving ring 5 is movably sleeved on the surface of the moving ring 5, and the triangular block 1 28 is located in the action path of the driving wheel 34;

[0076] The working principle and beneficial effects of the above technical solution are as follows: the movable ring 5 is movably sleeved on the surface of the movable ring 5, so that the movable ring 5 can be positioned and guided by the guide rod 15, and then when the threaded rod 4 rotates to drive the movable ring 5 to rise and fall, the movable ring 5 can be positioned and guided by the guide rod 15 to avoid the dipping chamber 1 from deviating, and then the triangular block 28 is located in the action path of the driving wheel 34, so that when the movable ring 5 moves upward, the driving wheel 34 can squeeze the triangular block 28.

[0077] Working principle and use process: in the initial state, the carrying plate 7 is located above the impregnation bin 1 and the limiting rod 2 33 contacts the inclined surface of the inclined surface block 10 to limit the inclined surface block 10. At this time, the distance between the extrusion wheel 13 and the fixed frame 14 is large;

[0078] Then, the fabric is wound on the surface of the carrier plate 7, and passes between the extrusion wheel 13 and the fixed frame 14, and then the servo motor 13 is started to drive the threaded rod 4 to rotate, so that the movable ring 5 engaged therewith moves downward along the axial direction of the threaded rod 4 and the guide rod 15, thereby driving the carrier plate 7 at the bottom end of the curved connecting rod 6 to move down to the inner cavity of the impregnation bin 1. At this time, the inclined block 10 is separated from the limiting rod 2 33, and the extrusion wheel 13 is driven by the tension of the spring assembly 8 to extrude the fabric, so that the fabric is clamped and limited by the extrusion wheel 13 and the fixed frame 14, and then the antibacterial solution is output to the inner cavity of the impregnation bin 1, and then the servo motor 13 is started again to drive the carrier plate 7 at the bottom end of the curved connecting rod 6 to move up and down;

[0079] As a result, the fabric shakes up and down, and shakes the antibacterial solution in the inner cavity of the impregnation chamber 1 to keep it active. At the same time, the moving ring 5 presses the piston rod 18. When the piston rod 18 moves upward in the inner cavity of the piston cylinder 16, the external air is sucked into the inner cavity of the piston cylinder 16 through the one-way air inlet valve 19. When the moving ring 5 presses the piston rod 18 downward, the air in the inner cavity of the piston cylinder 16 is transported to the inner cavity of the compression cylinder 21 along the one-way air outlet valve 20, and then the compression plate 23 is driven by the extrusion spring 22 to compress the air in the inner cavity of the compression cylinder 21.

[0080] After the impregnation is completed, the servo motor 13 is started to drive the carrier plate 7 to rise, firstly making the limit rod 132 contact with the inclined surface of the triangular block 2 35, thereby driving the inclined surface block 10 to move through the extrusion of the limit rod 132, thereby driving the extrusion wheel 13 to move a distance toward the fixed frame 14, so that the fabric is strongly and stably extruded by the extrusion wheel 13 and the fixed frame 14, so that the fabric is deformed;

[0081] Then, the servo motor 12 is started to drive the extrusion wheel 13 to rotate, so that the fabric passes between the extrusion wheel 13 and the fixed frame 14. Then, the staff connects one end of the fabric to the external receiving device from the bottom of the extrusion wheel 13 and the fixed frame 14, and fixes the fabric, so that the entire fabric passes through the extrusion wheel 13 and the fixed frame 14 for extrusion and deformation, so that the antibacterial solution inside the fabric is discharged, and the fabric is slowly transported by the rotation of the extrusion wheel 13;

[0082] At this time, the driving wheel 34 contacts the inclined surface of the triangular block 28 and squeezes the triangular block 28, and the triangular block 28 drives the closing block 27 to move in the direction of the limit spring 26, so that the conveying pipe 24 is connected, and the high-pressure air is conveyed to the inner cavity of the heating chamber 29 along the conveying pipe 24, and then heated by the heating plate 30 to become hot air and blown to the surface of the fabric being squeezed and deformed by the squeezing wheel 13, so as to dry it;

[0083] When the material is completely unloaded, the carrying plate 7 moves upward so that the second limiting rod 33 contacts the inclined surface block 10 , thereby separating the extrusion wheel 13 from the fixing frame 14 .
