Description

Technical Field

[0001] This application belongs to the technical field of non-woven fabric production, and particularly relates to an antibacterial non-woven fabric and its production process. Background Art

[0002] Non-woven fabric, also known as non-woven cloth or spunbonded fabric, is a sheet, web or batt made of fibers arranged in a directional or random pattern and joined together by friction, entanglement or adhesion, or a combination of these methods. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, lightweight, non-flammable, easy to decompose, non-toxic, non-irritating, rich in colors, low in price, recyclable, etc. After antibacterial treatment, the product does not mildew and can isolate the erosion of bacteria and insects in the liquid, and does not mildew or rot.

[0003] The existing Chinese patent with the publication number CN111411513B discloses an antibacterial non-woven fabric. Using modified acrylic fiber as the matrix, the modified acrylic fiber is impregnated in a silver antibacterial solution. After impregnation, it is placed in a water bath shaker for shaking, taken out, washed with water, and then naturally dried to obtain an antibacterial non-woven fabric chelated with silver atoms.

[0004] Although the above non-woven fabric provides antibacterial performance, its preparation method by soaking and dipping consumes a large amount of energy in the later water removal process and results in uneven density of the disinfectant solution. Therefore, improvements are made. Summary of the Invention

[0005] The purpose of this application is to address the above-mentioned existing technical problems and provide an antibacterial non-woven fabric and its production process, which can spray the silver antibacterial solution by spraying, save the energy consumption of later water removal, and accelerate the production speed.

[0006] This application provides an antibacterial non-woven fabric, including:

[0007] A core layer;

[0008] A skin layer disposed on the outer surface of the core layer;

[0009] A silver antibacterial layer formed by spraying a silver antibacterial solution between the core layer and the skin layer;

[0010] Wherein, both the core layer and the skin layer are made of modified acrylic fiber.

[0011] The antibacterial non-woven fabric provides antibacterial properties through the silver antibacterial layer between the core layer and the skin layer. The modified acrylic fiber and the silver antibacterial solution are chelated to obtain silver atoms. At the same time, the silver antibacterial layer has a certain adhesiveness between the core layer and the skin layer, and by placing the silver atoms between the core layer and the skin layer, the structural stability between the silver atoms and the non-woven fabric is further improved.

[0012] The modified acrylic fiber uses amino fatty alcohol M as a starting material. The cyanide reaction of the amino acrylic fiber on the amino fatty alcohol M obtains a modified acrylic fiber intermediate A. An active group amidohydrazone group is introduced into the acrylic fiber, which has a strong chelating adsorption effect on elemental silver. Then, the alcohol hydroxyl group of the modified acrylic fiber intermediate A is converted into sodium alcohol in an alkaline aqueous solution, and an esterification reaction occurs with 3-mercaptoisobutyric acid, and an adsorptive functional group thiol is introduced into the acrylic fiber. In this way, the prepared modified acrylic fiber has a dual active group of amidohydrazone group and thiol group. When the modified acrylic fiber is contacted with a silver antibacterial liquid, the dual active groups can firmly adsorb silver atoms and fix them on the surface of the acrylic fiber. Since the silver and the coordination group are chemically bonded, the silver layer of the obtained silver-plated fiber has a strong bonding force with the substrate.

[0013] The present application also provides a production process for antibacterial nonwoven fabrics, the specific steps of which include:

[0014] S1, preparing a core layer and a skin layer, and placing the core layer and the skin layer on a production device;

[0015] S2, spraying the silver antibacterial liquid onto the upper side of the skin layer through the production equipment;

[0016] S3, pressing the core layer and the skin layer sides together, and then heating them at a constant temperature through production equipment.

[0017] When producing antibacterial non-woven fabrics, they are transported into the production equipment through the core layer and the skin layer. The core layer is placed between the two skin layers. In the horizontal conveying area of ​​the skin layer, the silver antibacterial liquid is sprayed on the upper side of the skin layer, and then the sides of the core layer and the skin layer are pressed and closed and moved along the direction of gravity. At the same time, a pair of pressing rollers act on the outer side of the skin layer to make the silver antibacterial liquid between the skin layer and the core layer more evenly distributed, further improving the tightness of the connection between the skin layer and the core layer, and continue to heat it at a constant temperature, controlling the temperature at 60-70°C to increase the reaction rate of chelated silver atoms.

[0018] Furthermore, the production equipment includes:

[0019] Conveying rollers, used to convey the core layer and the skin layer;

[0020] A spraying mechanism, corresponding to the cortex;

[0021] Hot pressing wheel, placed on the production equipment;

[0022] A pressure roller is placed on the outer side of the cortex;

[0023] The constant temperature room is provided with a plurality of guide rollers.

[0024] The drive roller is used to convey the core layer and the skin layer. The silver antibacterial liquid is sprayed onto the skin layer through a spraying mechanism. The sides of the skin layer and the core layer are pressed together by a hot pressing wheel. The pressing roller acts on the outer side of the skin layer to improve the connection tightness between the skin layer and the core layer. At the same time, it improves the uniformity of the distribution of the silver antibacterial liquid between the core layer and the skin layer. The constant temperature chamber is used to maintain the temperature controlled at 60 - 70 °C.

[0025] Further, the spraying mechanism includes:

[0026] A spraying housing through which the skin layer passes through;

[0027] An atomizing generator installed on the spraying housing;

[0028] A spraying port placed inside the spraying housing;

[0029] A blower installed on the spraying housing;

[0030] A connecting channel connected between the blower and the spraying port;

[0031] A first adjusting mechanism placed between the spraying port and the spraying housing;

[0032] Among them, the spraying housing is provided with a receiving groove on one side of the spraying port. The spraying housing is provided with a liquid storage cavity, and the atomizing generator is installed and connected to the liquid storage cavity.

[0033] The liquid storage cavity is installed on the spraying housing. The atomizing generator turns the silver antibacterial liquid in the liquid storage cavity into an atomized state. Then, the blower blows air into the connecting channel, and the atomized silver antibacterial liquid flows through the connecting channel and is sprayed out from the spraying port. The spraying port is placed inside the spraying housing. When the skin layer moves through the inside of the spraying housing, the silver antibacterial liquid sprayed out from the spraying port is sprayed onto the skin layer. The first adjusting mechanism is used to adjust the spraying angle of the spraying port, facilitating the adjustment of the spraying amount per unit area on the skin layer. When the atomized silver antibacterial liquid flows in the connecting channel, a small amount of the atomized silver antibacterial liquid re - aggregates into water droplets on the side wall of the connecting channel and is received through the receiving groove for convenient recycling, further ensuring the uniformity of the silver antibacterial liquid sprayed onto the skin layer.

[0034] Further, the spraying mechanism further includes:

[0035] An electric field generator installed on the spraying housing and on the other side of the spraying port;

[0036] A second adjusting mechanism placed between the electric field generator and the spraying housing.

[0037] The electric field generator generates an electric field. The electric field generator is placed on the side of the spraying port. When the atomized silver antibacterial liquid is sprayed outwards from the spraying port, there are silver ions in the silver antibacterial liquid. Under the action of the electric field, the larger the atomized particles of the silver antibacterial liquid, the more silver ions it contains. The atomized silver antibacterial liquid ejected is sorted and layered through the electric field, so that the silver antibacterial liquid is regularly distributed on the cortex, and it is ensured that the silver antibacterial liquid ejected from the spraying port is all placed on the cortex. However, during the movement of the cortex, it will pass through the silver antibacterial liquid corresponding to different levels, thereby ensuring higher uniformity of the silver antibacterial liquid sprayed on the cortex. The second adjustment mechanism is used to adjust the electric field generator so that the electric field generated by the electric field generator is always perpendicular to the ejection direction of the spraying port.

[0038] Further, the liquid storage cavity includes:

[0039] An air inlet;

[0040] Connection ports, several of which are provided and are placed between the connection channel and the liquid storage cavity;

[0041] A boss, placed in the connection channel and connected to the connection port.

[0042] The air inlet is installed in the liquid storage cavity. A filter screen is installed at the air inlet. The connection ports correspond to the boss. When the air flow generated by the fan passes through the boss, the Venturi effect is generated, creating a negative pressure to extract the atomized silver antibacterial liquid in the liquid storage cavity into the connection channel, further improving the economical use of the silver antibacterial liquid.

[0043] Further, the first adjustment mechanism includes:

[0044] An adjustment plate, on which the spraying port is placed;

[0045] A rotating shaft, installed on the adjustment plate;

[0046] A first adjustment motor, installed and connected to the rotating shaft;

[0047] Among them, the spraying housing is provided with an adjustment groove adapted to the adjustment plate.

[0048] The first adjustment motor drives the rotating shaft to rotate. The rotating shaft is integrally connected to the adjustment plate. The rotating shaft is hinged between the spraying housing. The adjustment groove is arc-shaped, and the axis of the adjustment groove is the same as the axis of the rotating shaft, which is convenient for the adjustment of the sealing performance between the adjustment plate and the spraying housing when the adjustment plate rotates.

[0049] Further, the second adjustment mechanism includes:

[0050] An elastic member, placed between one end of the electric field generator and the spraying housing;

[0051] A second adjustment motor, installed on the spraying housing;

[0052] The cam is installed on the output shaft of the second adjustment motor;

[0053] Wherein, the other end of the electric field generator is movably connected to the spraying housing.

[0054] The electric field generator is hinged to the spraying housing. When the second adjustment motor controls the cam to rotate, the electric field generator rotates around its hinge axis to realize the adjustment of the electric field generator. The elastic member acts on the electric field generator to improve the structural stability between the electric field generator and the spraying housing.

[0055] The beneficial effects of this application are:

[0056] 1. The antibacterial non-woven fabric provides antibacterial properties through the silver antibacterial layer between the core layer and the skin layer. By placing silver atoms between the core layer and the skin layer, the structural stability between the silver atoms and the non-woven fabric is further improved.

[0057] 2. In the production equipment, when the skin layer moves through the spraying housing, the silver antibacterial liquid sprayed from the spraying port is sprayed on the skin layer, and the first adjustment mechanism is used to adjust the spraying angle of the spraying port.

[0058] 3. The electric field makes the silver antibacterial liquid regularly distributed on the skin layer, so as to ensure that the silver antibacterial liquid sprayed on the skin layer has higher uniformity. The second adjustment mechanism is used to adjust the electric field generator.

[0059] 4. When the air flow generated by the fan passes through the boss, the Venturi effect is generated, creating a negative pressure to extract the atomized silver antibacterial liquid in the liquid storage cavity into the connection channel, further improving the conservation of the silver antibacterial liquid.

[0067] Next, the embodiments of the present application will be described in detail in conjunction with the accompanying drawings, through specific embodiments and their application scenarios.

[0068] Embodiment 1:

[0069] As Figure 1 shown, the embodiment of the present application provides an antibacterial non-woven fabric, including:

[0070] Core layer 100;

[0071] Skin layer 110, disposed on the outer surface of the core layer 100;

[0072] Silver antibacterial layer 120, formed by spraying silver antibacterial liquid between the core layer 100 and the skin layer 110;

[0073] Among them, both the core layer 100 and the skin layer 110 are made of modified acrylic fiber.

[0074] The antibacterial non-woven fabric provides antibacterial properties through the silver antibacterial layer 120 between the core layer 100 and the skin layer 110. The modified acrylic fiber and the silver antibacterial liquid obtain chelated silver atoms. At the same time, the core layer 100 and the skin layer 110 have a certain degree of adhesion through the silver antibacterial layer 120, and the structural stability between the silver atoms and the non-woven fabric is further improved by placing the silver atoms between the core layer 100 and the skin layer 110.

[0075] The modified acrylic fiber uses amino fatty alcohol M as a starting material. The cyanide reaction of the amino acrylic fiber on the amino fatty alcohol M obtains a modified acrylic fiber intermediate A. An active group amidohydrazone group is introduced into the acrylic fiber, which has a strong chelating adsorption effect on elemental silver. Then, the alcohol hydroxyl group of the modified acrylic fiber intermediate A is converted into sodium alcohol in an alkaline aqueous solution, and an esterification reaction occurs with 3-mercaptoisobutyric acid, and an adsorptive functional group thiol is introduced into the acrylic fiber. In this way, the prepared modified acrylic fiber has a dual active group of amidohydrazone group and thiol group. When the modified acrylic fiber is contacted with a silver antibacterial liquid, the dual active groups can firmly adsorb silver atoms and fix them on the surface of the acrylic fiber. Since the silver and the coordination group are chemically bonded, the silver layer of the obtained silver-plated fiber has a strong bonding force with the substrate.

[0076] Embodiment 2:

[0077] The present application also provides a production process for antibacterial nonwoven fabrics, the specific steps of which include:

[0078] S1, preparing a core layer 100 and a skin layer 110, and placing the core layer 100 and the skin layer 110 on a production device 200;

[0079] S2, spraying the silver antibacterial liquid onto the upper side of the skin layer 110 through the production equipment 200;

[0080] S3, pressing the core layer 100 and the skin layer 110 side edges together, and then heating them at a constant temperature by the production equipment 200.

[0081] When producing the antibacterial non-woven fabric, the core layer 100 and the skin layer 110 are conveyed into the production equipment 200, and the core layer 100 is placed between the two skin layers 110. In the horizontal conveying area of ​​the skin layer 110, the silver antibacterial liquid is sprayed on the upper side of the skin layer 110, and then the side edges of the core layer 100 and the skin layer 110 are pressed and closed and moved along the gravity direction. At the same time, a pair of pressing rollers 500 act on the outer side of the skin layer 110 to make the silver antibacterial liquid between the skin layer 110 and the core layer 100 more evenly distributed, further improve the connection tightness between the skin layer 110 and the core layer 100, and continue to heat it at a constant temperature, control the temperature at 60-70°C, and increase the reaction speed of chelated silver atoms.

[0082] Embodiment 3:

[0083] like Figures 2 - 4As shown in the figure, the embodiment of the present application provides a production process of antibacterial non-woven fabric. In addition to the above technical features, further, the production equipment 200 includes:

[0084] A conveying roller 210 for conveying the core layer 100 and the skin layer 110;

[0085] A spraying mechanism 300 corresponding to the skin layer 110;

[0086] A hot pressing wheel 220 placed on the production equipment 200;

[0087] A pressing roller 500 placed on the outer side of the skin layer 110;

[0088] A constant temperature chamber 600 provided with a plurality of guiding rollers.

[0089] The conveying roller is used to convey the core layer 100 and the skin layer 110. The silver antibacterial liquid is sprayed onto the skin layer 110 through the spraying mechanism 300. The sides of the skin layer 110 and the core layer 100 are pressed together through the hot pressing wheel 220. The pressing roller 500 acts on the outer side of the skin layer 110 to improve the connection tightness between the skin layer 110 and the core layer 100. At the same time, the distribution uniformity of the silver antibacterial liquid between the core layer 100 and the skin layer 110 is improved. The constant temperature chamber 600 is used to keep the temperature controlled at 60 - 70 °C.

[0090] Further, the spraying mechanism 300 includes:

[0091] A spraying housing 310 through which the skin layer 110 passes;

[0092] An atomizing generator 320 installed on the spraying housing 310;

[0094] A blower 340 installed on the spraying housing 310;

[0095] A connecting channel 350 connecting the blower 340 and the spraying port 330;

[0096] A first adjusting mechanism 360 placed between the spraying port 330 and the spraying housing 310;

[0097] Among them, the spraying housing 310 is provided with a receiving groove 370 on one side of the spraying port 330. The spraying housing 310 is provided with a liquid storage chamber 380. The atomizing generator 320 is installed and connected to the liquid storage chamber 380.

[0098] The liquid storage chamber 380 is installed on the spraying housing 310. The silver antibacterial liquid in the liquid storage chamber 380 is atomized by the atomizing generator 320. Then, the blower 340 blows air into the connection channel 350, and the atomized silver antibacterial liquid flows through the connection channel 350 and is ejected from the spraying port 330. The spraying port 330 is placed inside the spraying housing 310. When the skin layer 110 moves through the inside of the spraying housing 310, the silver antibacterial liquid ejected from the spraying port 330 is sprayed onto the skin layer 110. The first adjusting mechanism 360 is used to adjust the spraying angle of the spraying port 330, so as to facilitate the adjustment of the spraying amount per unit area on the skin layer 110. When the atomized silver antibacterial liquid flows in the connection channel 350, a small amount of the atomized silver antibacterial liquid re-aggregates into water droplets on the side wall of the connection channel 350 and is collected through the collecting groove 370, which is convenient for recycling and reusing, and further ensures the uniformity of the silver antibacterial liquid sprayed onto the skin layer 110.

[0101] A second adjusting mechanism 410, which is placed between the electric field generator 400 and the spraying housing 310.

[0102] The electric field generator 400 generates an electric field. The electric field generator 400 is placed on the side of the spraying port 330. When the spraying port 330 ejects atomized silver antibacterial liquid, there are silver ions in the silver antibacterial liquid. Under the action of the electric field, the larger the atomized particles of the silver antibacterial liquid, the more silver ions it contains. The atomized silver antibacterial liquid ejected is sorted and stratified through the electric field, so that the silver antibacterial liquid is regularly distributed on the skin layer 110, and it is ensured that the silver antibacterial liquid ejected from the spraying port 330 is all placed on the skin layer 110. However, the skin layer 110 will pass through the silver antibacterial liquid corresponding to different layers during the movement, so as to ensure higher uniformity of the silver antibacterial liquid sprayed on the skin layer 110. The second adjusting mechanism 410 is used to adjust the electric field generator 400 so that the electric field generated by the electric field generator 400 is always perpendicular to the ejection direction of the spraying port 330.

[0103] Furthermore, the liquid storage chamber 380 includes:

[0107] The air inlet 381 is installed in the liquid storage cavity 380. A filter screen is installed at the air inlet 381. The connection port 382 corresponds to the boss 351. When the air flow generated by the fan 340 passes through the boss 351, the Venturi effect is generated, creating a negative pressure to extract the atomized silver antibacterial liquid in the liquid storage cavity 380 into the connection channel 350, further improving the conservation of the silver antibacterial liquid.

[0108] Further, the first adjustment mechanism 360 includes:

[0109] An adjustment plate 361, on which the spraying port 330 is placed;

[0110] A rotating shaft 362, installed on the adjustment plate 361;

[0111] A first adjustment motor, installed and connected to the rotating shaft 362;

[0112] Among them, the spraying housing 310 is provided with an adjustment groove 363 adapted to the adjustment plate 361.

[0113] The first adjustment motor drives the rotating shaft 362 to rotate. The rotating shaft 362 is integrally connected to the adjustment plate 361. The rotating shaft 362 is hinged between the spraying housing 310. The adjustment groove 363 is arc-shaped, and the axis of the adjustment groove 363 is the same as the axis of the rotating shaft 362, facilitating the sealing between the adjustment plate 361 and the spraying housing 310 when the adjustment plate 361 rotates.

[0114] Further, the second adjustment mechanism 410 includes:

[0115] An elastic member 411, placed between one end of the electric field generator 400 and the spraying housing 310;

[0116] A second adjustment motor 412, installed on the spraying housing 310;

[0118] Among them, the other end of the electric field generator 400 is movably connected to the spraying housing 310.

[0119] The electric field generator 400 is hinged to the spraying housing 310. When the second adjustment motor 412 controls the cam 413 to rotate, the electric field generator 400 rotates around its hinge axis, realizing the adjustment of the electric field generator 400. Through the action of the elastic member 411 on the electric field generator 400, the structural stability between the electric field generator 400 and the spraying housing 310 is improved.
