More and more different types of fabrics have emerged. Knitted fabrics are made by bending yarns into loops and interlacing them with knitting needles. They are divided into warp knitted fabrics and weft knitted fabrics. They are one of the most widely used fabrics. Because of their soft texture, large extensibility and elasticity, they are often made into underwear, tights and sportswear, etc., and are welcomed and loved by consumers.

[0003] Patent CN220242641U discloses a knitted fabric, including a base layer and a surface layer, a tensile layer is arranged between the base layer and the surface layer, the tensile layer includes a plurality of tensile ribs, a plurality of covering yarns are evenly wound on the tensile ribs along the weft direction, the covering yarn includes a first winding and a second winding that are cross-wound with each other, the first winding and the second winding both include a yarn core and a wrapping wire spirally wound on the outside of the yarn core, the yarn core is twisted by a plurality of Kevlar fibers, and the wrapping wire is twisted by a plurality of polyester fibers.

[0004] However, the structure of the above-mentioned knitted fabrics is relatively tight. Once the human skin sweats, the sweat cannot be quickly absorbed and drained, and the sweat will adhere between the fabric and the skin, resulting in poor comfort. Utility Model Content

[0005] In order to improve the comfort of fabric, the present application provides an antibacterial knitted fabric.

[0006] The antibacterial knitted fabric provided in this application adopts the following technical solution:

[0007] An antibacterial knitted fabric comprises a mesh skin-friendly layer, an antibacterial layer, a sweat-absorbing layer and a surface layer, wherein the antibacterial layer is arranged on the mesh skin-friendly layer, and a first air vent is provided on the antibacterial layer, the sweat-absorbing layer is arranged on the antibacterial layer, a second air vent connected to the first air vent is provided on the sweat-absorbing layer, an elastic bag is provided on the hole wall of the second air vent, and the inner cavity of the elastic bag has a heat-shrinkable and cold-expandable part, the surface layer is arranged on the sweat-absorbing layer, and a sweat-absorbing strip is provided on the sweat-absorbing layer, one end of the sweat-absorbing strip extends into the second air vent, and the other end of the sweat-absorbing strip extends to the outer surface of the surface layer.

[0008] By adopting the above technical scheme, when the wearer's body surface temperature is low, the heat shrinkable and cold expansion component is in an expanded state, which expands the elastic bag and blocks the second air hole, thereby reducing the air permeability and improving the thermal insulation effect; when the wearer exercises or the temperature is high, the heat shrinkable and cold expansion component shrinks, the elastic bag recovers, the second air hole is in a conducting state, the wearer sweats on the body surface, and the sweat can flow through the mesh holes of the mesh skin-friendly layer and the air hole 1 of the antibacterial layer to the air hole 2 of the sweat-absorbing layer in turn, and flow to the outer surface of the surface layer under the action of the sweat-absorbing strip, so that the sweat is quickly absorbed and drained; when the wearer stops exercising or comes to an area with a lower temperature, the heat shrinkable and cold expansion component expands again, expands the elastic bag, and blocks the second air hole again. At this time, there may still be some sweat on the body surface, and the sweat can flow into the second air hole, and flow to the outer surface of the surface layer under the action of the sweat-absorbing strip. At the same time, the blocking of the second air hole can improve the thermal insulation effect, reduce the risk of the wearer catching a cold, and comprehensively improve the comfort of the fabric.

[0009] Preferably, the heat shrinkable and cold expandable component comprises an elastic capsule filled with thymopentin, and the elastic capsule is arranged in the elastic bag.

[0010] By adopting the above technical solution, thymopentin will solidify and expand when the temperature is below 20 degrees, expanding the elastic capsule and the elastic bag. Thymopentin will melt and shrink when the temperature is above 20 degrees, causing the elastic capsule to shrink and recover, and the elastic bag to shrink and recover synchronously.

[0011] Preferably, the antibacterial layer comprises a plurality of interwoven warp yarns and weft yarns, the weft yarns are flax fibers, and air holes are formed between adjacent warp yarns and weft yarns.

[0013] Preferably, the warp yarn has a plurality of medicine cavities filled with medicine liquid, and the side wall of the warp yarn is provided with a liquid outlet hole connected with the medicine cavity, and a reverse osmosis membrane is arranged on the liquid outlet hole.

[0014] By adopting the above technical solution, under normal circumstances, the drug solution will not flow out through the reverse osmosis membrane. When the drug solution in the drug cavity is subjected to external force and the pressure increases, part of the drug solution will flow through the reverse osmosis membrane to the air vent 1 for antibacterial disinfection.

[0015] Preferably, a thermal expansion and contraction component is provided in the medicine cavity.

[0016] By adopting the above technical scheme, when the body surface temperature is low, the thermal expansion and contraction component is in a contracted state, the pressure of the medicine liquid in the medicine cavity is small, and it is not easy to flow out from the reverse osmosis membrane; when the body surface temperature rises and sweat is produced, the thermal expansion and contraction component expands, thereby increasing the pressure of the medicine liquid in the medicine cavity, and the medicine liquid flows through the reverse osmosis membrane to the air vent 1, thereby sterilizing the fabric and the body surface.

[0017] Preferably, the mesh skin-friendly layer comprises a plurality of hygroscopic fibers and natural silk, the hygroscopic fibers and natural silk are weft-knitted to form a plurality of mesh holes, and the mesh holes are connected to the air permeable holes of the antibacterial layer.

[0018] By adopting the above technical solution, natural silk is soft, light, relatively cool, contains natural silk protein, is beneficial to skin health when worn, and heat and sweat can quickly flow to the first ventilation hole through the mesh, and flow to the outside of the fabric through the second ventilation hole.

[0019] Preferably, the surface layer comprises a reinforcing layer and a wear-resistant layer, the reinforcing layer is arranged on a side of the sweat-absorbing layer away from the antibacterial layer, and the wear-resistant layer is arranged on the reinforcing layer.

[0020] By adopting the above technical solution, a reinforcement layer is provided to improve the overall strength of the fabric, and a wear-resistant layer is provided to improve the service life of the fabric.

[0021] Preferably, the end of the sweat-absorbing strip facing away from the sweat-absorbing layer passes through the wear-resistant layer and extends outside the wear-resistant layer. The sweat-absorbing strip includes a moisture-conducting single core, and the outer side of the moisture-conducting single core is twisted with color-changing fibers. The color-changing fibers will change color after contacting the medicine in the medicine cavity.

[0022] By adopting the above technical solution, the medicine in the medicine cavity flows to the sweat-absorbing strip along with sweat, and the color-changing fibers of the sweat-absorbing strip change color when in contact with the medicine, reminding that the antibacterial function is normal and the medicine in the medicine cavity is sufficient. When the color-changing fibers do not change color after sweating, it means that the medicine cavity needs to be replenished with medicine.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] This fabric can keep warm at low temperatures, and can absorb moisture and resist bacteria at high temperatures.

[0025] The fabric has a medicine cavity filled with liquid medicine, which can be used to disinfect the fabric;

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] like Figure 1 , Figure 2 As shown, the antibacterial knitted fabric includes a mesh skin-friendly layer 1, an antibacterial layer 2, a sweat-absorbing layer 3 and a surface layer 4.

[0034] like Figure 1 , Figure 3 As shown, in this embodiment, the mesh skin-friendly layer 1 includes a plurality of hygroscopic fibers and natural silk, and the hygroscopic fibers and natural silk are weft-knitted to form a plurality of mesh holes, through which heat and sweat can be quickly discharged.

[0035] Among them, the hygroscopic fiber can be natural fiber, such as cotton fiber and bamboo fiber. Cotton fiber has the advantages of good hygroscopicity, good air permeability and comfortable wearing. In addition to good hygroscopicity, bamboo fiber also has antibacterial, anti-mite and environmental protection effects.

[0036] like Figure 1 , Figure 3 As shown, the antibacterial layer 2 is disposed on the mesh skin-friendly layer 1 , and a ventilation hole 23 is provided on the antibacterial layer 2 , and the ventilation hole 23 is connected to the mesh holes of the mesh skin-friendly layer 1 .

[0037] In this embodiment, the antibacterial layer 2 includes a plurality of interwoven warp yarns 21 and weft yarns 22 , and air holes 23 are formed between adjacent warp yarns 21 and weft yarns 22 .

[0038] Preferably, the weft yarn 22 is flax fiber, the warp yarn 21 has a plurality of medicine cavities 24 filled with medicine liquid, the side wall of the warp yarn 21 is provided with a liquid outlet 25 connected to the medicine cavity 24, a reverse osmosis membrane is arranged on the liquid outlet 25, and a thermal expansion and contraction part 26 is arranged in the medicine cavity 24.

[0039] The thermal expansion and contraction member 26 can be made of a temperature-sensitive polymer, such as polyacrylamide, poly-N-isopropylacrylamide, polymethacrylic acid, polyvinyl ether, polylactic acid-glycolic acid, etc. It is also possible to combine materials with different thermal expansion and contraction coefficients to form a composite material. Preferably, the thermal expansion and contraction member 26 can be deformed at 20 degrees to 30 degrees, which is more in line with actual needs.

[0040] The thermal expansion and contraction parts 26 can be implanted into the warp yarn 21 through microcapsule technology. Of course, the warp yarn 21 can be made of plastic fiber. The thermal expansion and contraction parts 26 are injected during molding, and the filling and replenishment of the liquid medicine can be done by injection.

[0041] By adopting the above method, at normal temperature, the antibacterial rate can reach 60%. When the thermal expansion and contraction component 26 expands due to heat, more liquid medicine flows out of the medicine cavity 24, and the antibacterial rate reaches 99%, and the logarithmic value reaches 2.0.

[0042] like Figure 1 , Figure 3 As shown, the sweat-absorbing layer 3 is arranged on the antibacterial layer 2, and the sweat-absorbing layer 3 is provided with a second air hole 31 connected to the first air hole 23. An elastic bag 32 is provided on the hole wall of the second air hole 31, and the inner cavity of the elastic bag 32 has a heat shrinkable and cold expansion part 33.

[0043] In this embodiment, the heat shrinkable and cold expandable member 33 includes an elastic capsule filled with thymopentin, which is arranged in the elastic bag 32. When the temperature is below 20 degrees, the thymopentin will solidify and expand, expanding the elastic capsule and the elastic bag 32. When the temperature is above 20 degrees, the thymopentin will melt and shrink, causing the elastic capsule to shrink and recover, and the elastic bag 32 to shrink and recover synchronously.

[0044] Specifically, the elastic capsule is coated with the thermosensitive phase change material through microencapsulation technology and implanted into the fiber, so that the fiber material has the function of absorbing, storing and releasing heat in the form of latent heat. During the temperature change process, the material changes phase between solid and liquid.

[0045] like Figure 1 , Figure 3 As shown, the surface layer 4 is arranged on the sweat-absorbing layer 3 . Preferably, the surface layer 4 includes a reinforcing layer 41 and a wear-resistant layer 42 . The reinforcing layer 41 is arranged on the side of the sweat-absorbing layer 3 away from the antibacterial layer 2 , and the wear-resistant layer 42 is arranged on the reinforcing layer 41 .

[0046] In this embodiment, the reinforcing layer 41 may be woven from nylon, polyester fiber or spandex, and the wear-resistant layer 42 may be made of aramid fiber. Aramid fiber has excellent wear resistance, tear resistance and high temperature resistance.

[0047] like Figure 3 , Figure 4As shown, the sweat-absorbing layer 3 is provided with a sweat-absorbing strip 5 , one end of the sweat-absorbing strip 5 extends into the second ventilation hole 31 , and the other end of the sweat-absorbing strip 5 extends to the outer surface of the surface layer 4 .

[0048] Specifically, the end of the sweat-absorbent strip 5 facing away from the sweat-absorbent layer 3 passes through the wear-resistant layer 42 and extends outside the wear-resistant layer 42. The sweat-absorbent strip 5 includes a moisture-conducting single core 51, and the outer side of the moisture-conducting single core 51 is twisted with color-changing fibers 52. The color-changing fibers 52 will change color after contacting the medicine in the medicine cavity 24.

[0049] The color-changing fiber 52 can be realized by using special color-changing dyes or coatings. These dyes or coatings can react with specific components in the antibacterial solution to cause color changes. For example, pH-sensitive dyes can be considered because certain components in the liquid medicine can change the pH of the environment. When the color-changing fiber 52 contacts the liquid medicine, the pH value of the environment changes, and the dye changes color accordingly.

[0050] In addition to color-changing dyes or coatings, nanomaterials with antibacterial and color-changing functions can also be considered. These nanomaterials can be embedded in the color-changing fibers 52 and change color when they come into contact with the liquid medicine.

[0051] The working principle of this embodiment is as follows: when the wearer's body surface temperature is low, the heat shrinkable and cold expansion member 33 is in an expanded state, the elastic bag 32 is expanded, and the air hole 2 31 is blocked to improve the heat preservation effect; when the wearer exercises or the temperature is high, the heat shrinkable and cold expansion member 33 contracts, the elastic bag 32 recovers, the air hole 2 31 is in a conducting state, the wearer sweats on the body surface, and the sweat can flow through the mesh holes of the mesh skin-friendly layer 1 and the air hole 1 23 of the antibacterial layer 2 to the air hole 2 31 of the sweat-absorbing layer 3 in turn, and flow to the outer surface of the surface layer 4 under the action of the sweat-absorbing strip 5, so that the sweat is quickly absorbed and drained, thereby improving the comfort of the fabric.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
