Description

TECHNICAL FIELD

[0001] The application relates to the technical field of textiles, and particularly discloses an anti-mosquito and antibacterial fabric and a jacket. BACKGROUND

[0002] The jacket is an important equipment for outdoor activities, and becomes the first choice of people for outdoor activities because of good air permeability, windproofness and waterproofness. With the rapid development of outdoor hiking and mountaineering, people have put forward new requirements for the comfort and functionality of outdoor clothes in order to resist the harm of outdoor harsh environment to the human body. In summer, there are many mosquitoes and bacteria outside, and how to prevent mosquito bites and bacterial growth becomes the focus of people. People need the jacket to not only quickly absorb moisture, but also have good anti-mosquito and antibacterial effects. Therefore, the development of the anti-mosquito and antibacterial fabric as the preparation fabric of the jacket can better meet the consumer demand and improve the market competitiveness of the product.

[0003] For the related technologies in the above, the inventors find that the anti-mosquito and antibacterial fabric used by the clothes with anti-mosquito and antibacterial effects on the market adopts a chemical dipping or coating method to fix the anti-mosquito and antibacterial agent on the fabric. Although this method can achieve certain anti-mosquito and antibacterial effects, the anti-mosquito and antibacterial agent is prone to falling off and unstable, resulting in poor anti-mosquito and antibacterial effects and durability of the fabric. SUMMARY

[0004] In order to improve the durability of the anti-mosquito and antibacterial effects of the fabric and improve the anti-mosquito and antibacterial performance of the fabric, the application provides an anti-mosquito and antibacterial fabric and a jacket.

[0005] In a first aspect, the application provides an anti-mosquito and antibacterial fabric, which adopts the following technical solution:

[0006] The anti-mosquito and antibacterial fabric comprises a base cloth layer, an anti-mosquito and antibacterial layer arranged on one side of the base cloth layer, and an inner layer arranged on the side of the anti-mosquito and antibacterial layer away from the base cloth layer. The base cloth layer comprises 240-380 parts by weight of base fibers and 30-50 parts by weight of functional components. The anti-mosquito and antibacterial layer comprises 150-250 parts by weight of antibacterial fibers and 100-150 parts by weight of anti-mosquito fibers. The inner layer comprises 100-200 parts by weight of warm-keeping carbon fibers, 50-100 parts by weight of ramie fibers and 20-50 parts by weight of ceramic powder fibers.

[0007] Through the above technical solution, the base fibers of the base cloth layer make the fabric have good wear resistance and washing resistance, and the addition of the functional components endows the base cloth layer of the fabric with more comprehensive performance. The inner layer mainly improves the warmth and comfort of the fabric. The warm-keeping carbon fibers and the ceramic powder fibers can lock heat and improve the warmth-keeping effect of the fabric. The ramie fibers have excellent air permeability and moisture absorption, can keep the skin dry and comfortable, and reduce bacterial growth and odor generation.

[0008] The mosquito-repellent and antibacterial fibers in the mosquito-repellent and antibacterial layer are functional fibers that are directly woven into the fabric through fiber integration, rather than achieving mosquito-repellent and antibacterial properties through surface coating or impregnation. This integration method makes the mosquito-repellent and antibacterial properties an integral part of the fabric itself, ensuring the stability and durability of these functional fibers in the fabric. It has stronger water resistance and will not easily fall off or shift even after repeated washing and mechanical friction, so it can continue to play its mosquito-repellent and antibacterial functions, significantly enhancing the durability of the fabric's mosquito-repellent and antibacterial effects.

[0009] Optionally, the antibacterial fiber comprises, by weight, 12-18 parts graphene, 20-30 parts polyethyleneimine, 2-6 parts silver nitrate and 30-40 parts polyethylene.

[0010] By adopting the above technical solution, compared with traditional antibacterial materials, graphene has the advantages of high surface activity, high reactivity and high biocompatibility. Its antibacterial principle is mainly through mechanical cutting. When bacteria adhere to the graphene fabric, the graphene physically destroys the bacteria through its sharp boundaries, thereby inhibiting the growth and reproduction of bacteria. This antibacterial mechanism is not only effective but also broad-spectrum, and can inhibit the growth of a variety of bacteria.

[0011] Silver nitrate provides silver ions to the antibacterial fibers. Silver ions are known for their broad-spectrum antibacterial effects. When graphene combines with silver ions, its antibacterial properties are significantly enhanced, which can more effectively inhibit and kill bacteria, fungi and other microorganisms, thus improving the antibacterial properties of the fabric. Graphene contains oxygen atoms, which can easily form hydrogen bonds, covalent bonds and other bonds, and can also form a stable composite structure through electrostatic adsorption. It has high chemical stability, and the silver ions in the graphene-silver composite material can be continuously released, making the antibacterial effect durable. After multiple washes and uses, the fabric can still maintain excellent antibacterial properties, significantly improving the fabric's washability and the durability of the antibacterial effect.

[0012] Optionally, the method for preparing the antibacterial fiber includes the following steps:

[0013] After dispersing graphene in water and sonicating for 30-40 minutes, polyethyleneimine was added, and sonication was continued. The pH was adjusted to 7-8 to obtain the dispersion.

[0014] Silver nitrate was added to the dispersion, and ammonia was added until the precipitate disappeared. The mixture was then microwaved at 100-120℃, cooled, and freeze-dried to obtain a graphene-silver blend.

[0015] The graphene-silver blend and polyethylene were mixed and added to water, and the mixture was heated and stirred at 40-60℃ for 6-8 hours to obtain the spinning solution. Antibacterial fibers were then prepared by electrospinning.

[0016] By adopting the above technical solution, the addition of silver ions enhances the antibacterial activity of graphene in antibacterial fibers. The graphene-silver composite material is used to prepare antibacterial fibers through electrospinning, so that the antibacterial fibers combine the long-lasting and stable antibacterial properties of graphene and silver ions. Even after multiple washes and uses, the antibacterial fibers can still maintain their stable antibacterial effect.

[0017] Optionally, by weight, the mosquito-repellent fiber comprises 20-25 parts bamboo fiber, 20-30 parts polyethylene, 8-12 parts mosquito-repellent microcapsules, and 30-40 parts polyester fiber; the mosquito-repellent microcapsules comprise permethrin, melamine resin, and tetrachlorpyrifos in a mass ratio of (2-8):(3-7):1.

[0018] By adopting the above technical solutions, both permethrin and tetrafluoroethylene have highly efficient, low-toxicity and long-lasting mosquito-repellent effects. Tetrafluoroethylene has excellent knockdown properties against mosquitoes, while permethrin has a lethal effect. The combination of the two as the core material of mosquito-repellent microcapsules can significantly enhance the efficacy and improve the dispersibility and stability of permethrin and tetrafluoroethylene in the microcapsules. This helps the two to be better and more evenly dispersed in the microcapsules, preventing precipitation or aggregation, thereby effectively prolonging the mosquito-repellent activity and durability of the mosquito-repellent fiber.

[0019] Optionally, the method for preparing the mosquito-repellent fiber includes the following steps:

[0020] Mosquito-repellent microcapsules were prepared by in-situ polymerization using permethrin and tetrachlorpyrifos as core materials and melamine resin as wall material. Mosquito-repellent fibers were prepared by mixing bamboo fiber and polypropylene as core material and mixing mosquito-repellent microcapsules and polyester fiber as skin material through core-skin composite spinning.

[0021] By adopting the above technical solution, mosquito-repellent fibers are prepared by core-sheath composite spinning. Polyester fiber, as the core layer, provides mechanical strength to the mosquito-repellent fiber. Microcapsule technology can form a physical barrier between the core material and the wall material, allowing the core material to slowly release through the wall material and exert its effect. Polyester fiber with added mosquito-repellent microcapsules as the core layer can stably and slowly release the effective ingredients in the mosquito-repellent microcapsules, thereby achieving a long-lasting mosquito-repellent effect. Bamboo fiber and polypropylene composite as the sheath layer further increases the spinnability, strength and durability of the mosquito-repellent fiber.

[0022] In addition, bamboo fiber has natural antibacterial properties, which can effectively inhibit the growth of bacteria and enhance the antibacterial properties of mosquito-repellent fibers. On the other hand, bamboo fiber has a special microporous structure inside, which, as the outer layer of mosquito-repellent fibers, can ensure that the active ingredients in mosquito-repellent microcapsules can be slowly released through the outer layer to achieve the mosquito-repellent effect.

[0023] Optionally, by weight, the functional components include 50-70 parts phenolic resin, 60-80 parts graphene dispersion slurry, 20-30 parts tea tree oil, 15-20 parts chitosan, 40-50 parts polar solution, 0.3-0.8 parts leveling agent, 1-4 parts waterproofing agent and 6-13 parts curing agent.

[0024] By adopting the above technical solution, phenolic resin has good heat resistance, corrosion resistance and mechanical strength, which can effectively improve the wear resistance and heat resistance of the base fabric layer.

[0025] Graphene not only has excellent antibacterial properties, but also good electrical conductivity, thermal conductivity, and UV resistance. As a functional component, it can be adsorbed onto the outermost base layer of a fabric to enhance its mosquito-repellent and antibacterial properties, as well as give it antistatic, warm, and UV-resistant properties. In addition, graphene is an ultra-thin and strong material that can form a physical barrier that prevents mosquitoes from penetrating the base layer, effectively preventing mosquito bites.

[0026] Tea tree oil and chitosan are both natural antibacterial agents with strong antibacterial, anti-inflammatory and insect-repellent effects. The combination of the two can further enhance the antibacterial and mosquito-repellent properties of the base fabric layer.

[0027] Optionally, by weight, the matrix fibers include 100-150 parts polyamide fiber, 50-80 parts acrylic fiber, 100-120 parts polyester fiber and 30-70 parts asbestos fiber.

[0028] By adopting the above technical solutions, the base fabric layer prepared from polyamide fiber, acrylic fiber, polyester fiber and asbestos fiber can form the first mosquito-proof and antibacterial barrier of the fabric. These fibers have high strength and abrasion resistance, which makes the base fabric layer less prone to damage during use and improves the durability of the fabric.

[0029] Optionally, the preparation method of antibacterial mosquito-repellent fabric includes the following steps:

[0030] The base fabric yarn is prepared by blending the base fibers, and then woven to obtain a pre-treated base fabric layer. The base fabric yarn is then woven to obtain a pre-treated base fabric layer. The pre-treated base fabric layer is then immersed in functional components for padding, drying and curing to obtain the base fabric layer. Antibacterial fibers and mosquito-repellent fibers are blended to prepare antibacterial and mosquito-repellent yarn, and then woven to obtain a mosquito-repellent and antibacterial layer. Inner layer yarn is blended with heat-insulating carbon fiber, ramie fiber and ceramic powder fiber, and then woven to obtain the inner layer. The woven base fabric layer, mosquito-repellent and antibacterial layer and inner layer are then stacked in sequence, and adjacent fabric layers are sewn together with metal wires and then glued.

[0031] By adopting the above technical solutions, the fabric successfully achieves multiple functions such as antibacterial, mosquito repellent, warmth retention, and breathability and moisture wicking through the blending of different fiber materials in the base fiber. Immersing the pre-treated base fabric layer in the functional components and then rolling and drying it significantly enhances the antistatic, antibacterial, mosquito repellent, and UV-resistant properties of the outer base fabric layer. After weaving, the three-layer fabric structure is sewn together with metal filaments and then glued to form a fabric, which further enhances the stability and durability of the fabric.

[0032] Secondly, this application provides a windproof jacket made from a mosquito-repellent and antibacterial fabric of this application.

[0033] By adopting the above technical solution, the down jacket of this application has excellent and long-lasting mosquito repellent and antibacterial effects.

[0034] In summary, this application has the following beneficial effects:

[0035] 1. The fabric of this application includes a base fabric layer, a mosquito-repellent and antibacterial layer, and an inner layer. The inner layer gives the fabric better warmth retention, breathability, moisture wicking, and comfort. The base fabric layer gives the fabric good comprehensive properties such as waterproofing, UV protection, breathability, and moisture wicking. By integrating mosquito-repellent and antibacterial fibers into the fabric, a mosquito-repellent and antibacterial layer is formed, making the mosquito-repellent and antibacterial properties an integral part of the fabric itself. This significantly enhances the durability of the fabric's mosquito-repellent and antibacterial properties and improves the fabric's mosquito-repellent and antibacterial characteristics.

[0036] 2. In the mosquito-repellent fiber of this application, mosquito-repellent microcapsules are incorporated into the mosquito-repellent fiber through core-sheath composite spinning. The core material of the mosquito-repellent microcapsule, permethrin and tetrachlorpyrifos, are combined as effective ingredients, which significantly improves the mosquito-repellent and insect-repellent properties of the mosquito-repellent fiber. At the same time, the core material can be slowly released outward through the wall material of the mosquito-repellent microcapsule and exert its effect, which significantly enhances the effectiveness and durability of the fabric's mosquito-repellent performance.

[0037] 3. The antibacterial fiber of this application contains graphene and silver ions to form a graphene-silver composite material, which significantly improves the antibacterial properties of the antibacterial fiber; the graphene in the functional components of the base fabric layer of this application further enhances the antibacterial, antistatic, and UV protection properties of the fabric, while tea tree oil and chitosan further enhance the antibacterial and insect-repellent effects of the fabric.

[0153] Mosquito repellency performance testing: The mosquito repellency performance of the fabric was tested by placing it in a repulsion tester in accordance with GB / T30126-2013 "Test and evaluation of mosquito repellency performance of textiles".

[0154] Antibacterial performance testing: The antibacterial performance of the fabric was tested according to GB / T20944.3-2008 "Evaluation of antibacterial properties of textiles - Part 3: Vibration method".

[0158] As shown in Table 7, the performance test data indicates that the mosquito-repellent and antibacterial fabric of this application has a mosquito repellency rate of ≥81.2%, demonstrating its strong mosquito-repellent and insect-repellent effect. The fabric also exhibits an inhibition rate of 97.2-99.2% against Staphylococcus aureus, 94.3-95.6% against Escherichia coli, and 90.3-91.2% against Candida albicans, demonstrating its effective antibacterial properties. Furthermore, the fabric maintains high mosquito-repellent and insect-repellent effects and antibacterial properties even after 50 washes, indicating its long-lasting mosquito-repellent and antibacterial performance.

[0159] According to the performance test data of Examples 1-6 and Comparative Examples 1-4, it can be seen that the fabric uses a blend of mosquito-repellent and antibacterial fibers to prepare a mosquito-repellent and antibacterial layer as part of the fabric. Through fiber integration, the mosquito-repellent and antibacterial properties become part of the fabric itself, which significantly enhances the mosquito-repellent and antibacterial properties of the fabric. Even after multiple washes, it still has a significant mosquito-repellent and antibacterial effect, effectively improving the durability of the fabric's mosquito-repellent and antibacterial effect. The use of functional components further enhances the mosquito-repellent and antibacterial properties of the fabric.

[0160] According to the performance test data of Examples 1-6 and Example 7, the addition of silver ions gives the antibacterial fiber stronger antibacterial properties. Compared with the fabric made of antibacterial fiber with only graphene added as an effective antibacterial component, the graphene-silver composite component effectively enhances the antibacterial properties of the fabric made of antibacterial fiber and can maintain a stable antibacterial effect after multiple washes.

[0161] According to the performance test data of Examples 1-6 and Example 8, both permethrin and tetrachlorpyrifos have highly efficient, low-toxicity and long-lasting mosquito repellent effects. The fabric made of mosquito repellent fibers prepared by combining permethrin and tetrachlorpyrifos with mosquito repellent microcapsules has a stronger mosquito repellent and insect-repelling effect than the fabric made of mosquito repellent fibers prepared by mosquito repellent microcapsules containing only permethrin.

[0162] According to the performance test data of Examples 1-6 and Examples 9-12, the graphene in the functional components further enhances the antibacterial properties of the fabric, and the addition of tea tree oil and chitosan can effectively improve the mosquito and insect repellent effect of the fabric. Moreover, the mosquito and insect repellent effect is better when tea tree oil and chitosan are used in combination.

[0163] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
