Description

Technical Field

[0001] The utility model relates to the technical field of textile fabrics, and particularly relates to an antibacterial, anti-ultraviolet and breathable composite fabric. Background Art

[0002] With the acceleration of the pace of life, consumers' demands for outdoor products are becoming more and more diversified, and they pay more attention to their health, comfort, safety and protection functions. Chemical fibers such as polyester and nylon have the advantages of high strength, good elasticity, wear resistance and heat resistance, and are particularly suitable for sports, leisure, travel equipment and protective fabrics. In recent years, lightweight chemical fiber outdoor products with anti-ultraviolet and antibacterial functions have led the trend of the times and are loved by many consumers. Generally speaking, thick and tightly structured fabrics themselves have a certain anti-ultraviolet effect, but their comfort and breathability are poor, which is obviously not suitable for summer clothing; thin and loosely structured fabrics are suitable for summer, but their anti-ultraviolet effect is poor. Therefore, how to endow lightweight chemical fiber fabrics with excellent and durable anti-ultraviolet properties has become a difficult point in the development of high-end outdoor products. In addition, chemical fibers themselves have poor moisture absorption and moisture conduction properties, and wearing them has a stuffy feeling. In summer, when sweating a lot, the fabric is prone to bacteria breeding, which will seriously affect its application in healthy and comfortable outdoor clothing and the improvement of product grades. Conventional hydrophilic and antibacterial finishing is difficult to endow chemical fiber fabrics with ideal durable moisture absorption and antibacterial properties, and their ecological and environmental protection properties are also poor.

[0003] CN 216659146 U discloses an anti-ultraviolet woven fabric, including: a woven fabric layer. A layer of antibacterial layer and an anti-ultraviolet coating are fixedly arranged on the woven fabric layer; a nylon reinforcement layer and an anti-ultraviolet fabric layer are fixedly arranged on the side of the woven fabric layer away from the antibacterial layer. The anti-ultraviolet coating used in this fabric is nano-titanium dioxide, which has poor adhesion and poor washing resistance, so the anti-ultraviolet performance is not good. In addition, the weaving method of the anti-ultraviolet fabric layer uses three different weft yarns, the process is complicated, and the structure of the profiled polyester fiber in the weft yarn is complex, which is not conducive to industrial production.

[0004] It is necessary to develop new composite fabrics to improve the antibacterial and anti-ultraviolet properties, while taking into account lightness and breathability, and enhancing the wearing comfort and functional durability of lightweight chemical fiber products. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides an antibacterial, anti-ultraviolet and breathable composite fabric, which has good antibacterial and anti-ultraviolet properties, good wash and wear durability, and good moisture absorption and sweat discharge properties, and combines lightness, breathability and functional durability.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An antibacterial, anti-ultraviolet and breathable composite fabric, comprising an anti-ultraviolet outer layer and an antibacterial inner layer. The anti-ultraviolet outer layer is woven from a first yarn, and the first yarn includes a first anti-ultraviolet core wire and a hydrophilic coating wire wound around the outside of the first anti-ultraviolet core wire;

[0008] The antibacterial inner layer is woven from a second yarn, and the second yarn includes a second anti-ultraviolet core wire and a hydrophilic antibacterial coating wire wound around the outside of the second anti-ultraviolet core wire; both the first anti-ultraviolet core wire and the second anti-ultraviolet core wire are hydrophobic profiled anti-ultraviolet fibers.

[0009] Furthermore, the cross-section of the profiled anti-ultraviolet fiber is Y-shaped, triangular, cross-shaped or pentagram-shaped, etc. The porosity of the profiled fiber is relatively high, providing capillary channels for the diversion of sweat and moisture.

[0010] Furthermore, the profiled anti-ultraviolet fiber is a hydrophobic chemical fiber, such as polyester fiber.

[0011] In the present utility model, the second anti-ultraviolet core wire of the second yarn in the antibacterial inner layer is hydrophobic, and the antibacterial coating wire is hydrophilic, so that sweat can be transported along the surface layer of the second yarn to the first yarn in the outer layer. At the same time, sweat is not easily accumulated on the inner core wire, and the water evaporation rate is relatively fast.

[0012] The first yarn of the anti-ultraviolet outer layer also has a hydrophobic first anti-ultraviolet core wire and a hydrophilic coating wire, so that sweat can be transported from the surface layer of the first yarn to the outside for evaporation. And the first anti-ultraviolet core wire is protected by the coating wire inside, so it is not easily affected by daily use wear and washing, improving its durability and washability.

[0013] In the present utility model, the anti-ultraviolet outer layer and the antibacterial inner layer respectively include a first anti-ultraviolet core wire and a second anti-ultraviolet core wire. In the anti-ultraviolet outer layer, the first anti-ultraviolet core wire first absorbs and reflects ultraviolet rays in the first step. The ultraviolet rays that are not absorbed or reflected enter the antibacterial inner layer, and the second anti-ultraviolet core wire in the antibacterial inner layer further absorbs the ultraviolet rays entering the inner layer. Through the cooperation of the two layers, the anti-ultraviolet effect of the composite fabric is improved.

[0014] In the present utility model, the first anti-ultraviolet core wire or the second anti-ultraviolet core wire can obtain a hydrophobic anti-ultraviolet core wire by attaching or coating a hydrophobic ultraviolet absorber on the surface of the hydrophobic chemical fiber.

[0015] In the first yarn, the hydrophilic coating wire wound around the outside of the first anti-ultraviolet core wire mainly plays a role in guiding moisture and discharging sweat, and at the same time protects the first anti-ultraviolet core wire.

[0016] In the second yarn, the antibacterial coating wire wound around the outer side of the second ultraviolet-resistant core wire is a hydrophilic antibacterial fiber. Since the living environment of bacteria contains water, the hydrophilic antibacterial fiber is beneficial to killing bacteria. Moreover, the hydrophilic antibacterial fiber is located in the antibacterial inner layer and is protected by the ultraviolet-resistant outer layer, thus improving the wash durability performance.

[0017] Furthermore, in the antibacterial and ultraviolet-resistant breathable composite fabric, a skin-friendly layer is arranged on the outer side of the antibacterial inner layer.

[0018] Furthermore, a plurality of ventilation holes are provided on the skin-friendly layer, so that sweat or water vapor generated by the skin can be discharged outward through the ventilation holes, keeping the skin dry.

[0019] In summary, the following beneficial effects can be achieved by applying the present utility model:

[0020] 1. In the two-layer structure of the present utility model, the first ultraviolet-resistant core wire and the second ultraviolet-resistant core wire are combined to cooperate in ultraviolet resistance, thereby improving the ultraviolet resistance performance of the composite fabric.

[0021] 2. Both the first yarn of the ultraviolet-resistant outer layer and the second yarn of the antibacterial inner layer have a hydrophobic core wire and a hydrophilic wrapping wire. Sweat can be transported from the surface wrapping wire of the second yarn to the wrapping wire of the first yarn, and then evaporated in the outside world. The hydrophobic core wire will not store sweat and will conduct the liquid to the outer layer, thereby improving the evaporation rate of sweat and having good breathable moisture-permeable performance.

[0022] 3. The hydrophobic first ultraviolet-resistant core wire and the second ultraviolet-resistant core wire are profiled fibers and have a large porosity, which is beneficial to the discharge of sweat and water vapor.

[0023] 4. The first ultraviolet-resistant core wire of the ultraviolet-resistant outer layer is protected by a hydrophilic wrapping wire and is not easily affected by external abrasion or washing, thereby improving the wash durability performance.

[0024] 5. The antibacterial coating wire of the antibacterial inner layer is a hydrophilic antibacterial fiber, which is beneficial to killing bacteria and has good wash durability performance.

[0025] 6. The composite fabric of the present utility model takes into account antibacterial, ultraviolet-resistant, and breathable moisture-permeable performance, and has a simple structure, a light and thin fabric, and good durability. It is suitable for summer outdoor use and has great application and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example 1

[0034] Referring to Figure 1 , this embodiment provides an antibacterial and ultraviolet-resistant breathable composite fabric, including an ultraviolet-resistant outer layer 1 and an antibacterial inner layer 2. The ultraviolet-resistant outer layer 1 is woven from the first yarn, and the antibacterial inner layer 2 is woven from the second yarn 21. Both the first yarn and the second yarn are core-spun yarns with similar structures. Referring to Figure 2, including a core wire and a covering wire wound around the outside of the core wire. Specifically, the first yarn includes a first ultraviolet-resistant core wire and a hydrophilic covering wire wound around the outside of the first ultraviolet-resistant core wire; the second yarn 21 includes a second ultraviolet-resistant core wire 211 and an antibacterial covering wire 212 wound around the outside of the second ultraviolet-resistant core wire; the first ultraviolet-resistant core wire and the second ultraviolet-resistant core wire are profiled ultraviolet-resistant fibers, the antibacterial covering wire 212 is a hydrophilic fiber, and the profiled ultraviolet-resistant fibers are hydrophobic chemical fibers. In a preferred embodiment, the profiled ultraviolet-resistant fiber is a profiled ultraviolet-resistant polyester fiber.

[0035] The cross-section of the profiled ultraviolet-resistant fiber can be Y-shaped, triangular, cross-shaped, pentagram-shaped, etc. Refer to Figure 3 , which gives a schematic structural diagram of a profiled ultraviolet-resistant fiber with a Y-shaped cross-section.

[0036] In the profiled fiber, generally there are protrusions and grooves between adjacent protrusions, resulting in a higher porosity than that of an ordinary circular cross-section, which can accommodate part of the sweat and moisture. However, since the profiled ultraviolet-resistant fiber is hydrophobic, it will not store sweat for a long time, but direct the sweat and moisture to the outer hydrophilic covering wire, and these pores provide capillary channels for the diversion of sweat and moisture.

[0037] In this embodiment, the sweat or moisture generated by the human body is directed to the antibacterial covering wire of the second yarn of the antibacterial inner layer 2, further transported to the first yarn of the ultraviolet-resistant outer layer 1, and transported to the outside by the hydrophilic covering wire for evaporation.

[0038] When the moisture on the hydrophilic covering wire evaporates, the moisture in the pores of the core wires inside the second yarn and the first yarn can gradually transfer outward. Therefore, the first yarn and the second yarn play a good role in absorbing and discharging sweat and have a quick-drying property. Sweat is not easy to accumulate on the inner core wire, and the moisture evaporation rate is relatively fast.

[0039] In this embodiment, the ultraviolet-resistant outer layer 1 and the antibacterial inner layer 2 respectively include a first ultraviolet-resistant core wire and a second ultraviolet-resistant core wire. When in use, ultraviolet rays first irradiate the ultraviolet-resistant outer layer 1, and the first ultraviolet-resistant core wire first absorbs and reflects the ultraviolet rays in the first step. The ultraviolet rays that are not absorbed or reflected enter the antibacterial inner layer 2 deep in the fabric, and the second ultraviolet-resistant core wire in the antibacterial inner layer 2 further absorbs the ultraviolet rays entering the inner layer, further reducing the probability of the human skin being irradiated by ultraviolet rays. Through the collaborative combination of the first ultraviolet-resistant core wire and the second ultraviolet-resistant core wire, the ultraviolet-resistant effect of the composite fabric is improved.

[0040] In this embodiment, the first ultraviolet-resistant core wire or the second ultraviolet-resistant core wire can obtain a hydrophobic ultraviolet-resistant core wire by attaching or coating a hydrophobic ultraviolet absorber on the surface of the hydrophobic chemical fiber.

[0041] The ultraviolet absorber can be various common types of ultraviolet absorbers, but it is required to be hydrophobic. Common ultraviolet absorbers include organic ultraviolet absorbers and inorganic ultraviolet absorbers. Organic ultraviolet absorbers include salicylate ultraviolet absorbers, benzophenone ultraviolet absorbers, benzotriazole ultraviolet absorbers, etc. Inorganic ultraviolet absorbers are generally nanomaterials, such as nano-titanium dioxide, nano-zinc oxide, etc., and surface hydrophobic treatment is required.

[0042] In a preferred embodiment, the profiled anti-ultraviolet fiber is a profiled polyester fiber, which is treated with a benzotriazole ultraviolet absorber to obtain a profiled anti-ultraviolet polyester fiber.

[0043] The profiled polyester fiber can be composed of monofilament profiled polyester fibers, or can be formed by twisting and winding the monofilaments of multi-strand profiled polyester fibers.

[0044] In the first yarn, the hydrophilic coating wire wound outside the first anti-ultraviolet core wire mainly plays a role in guiding moisture and sweat, and at the same time protects the first anti-ultraviolet core wire, making the first anti-ultraviolet core wire not easily affected by daily use wear and washing, and improving the durability and washability of the composite fabric.

[0045] The hydrophilic coating wire can be natural fibers such as cotton fiber and bamboo fiber, or hydrophilic viscose fiber, or chemical fiber modified by hydrophilic modification, such as chitosan modification. If chitosan modification is used, the first yarn can also have certain antibacterial properties.

[0046] In the second yarn, the antibacterial coating wire wound outside the second anti-ultraviolet core wire is a hydrophilic antibacterial fiber. Since bacteria generally survive in an aqueous environment, the hydrophilic antibacterial fiber is beneficial to killing bacteria. And the hydrophilic antibacterial fiber is located in the antibacterial inner layer and is also protected by the anti-ultraviolet outer layer, improving the washability and durability.

[0047] Common hydrophilic antibacterial fibers include antibacterial fibers modified with nano-silver or silver ions, antibacterial fibers modified with chitosan antibacterial fibers or chitosan antibacterial agents, antibacterial fibers modified with quaternary ammonium salt antibacterial agents, antibacterial fibers modified with organosilicon betaine, etc.

[0048] In a preferred embodiment, the antibacterial coating wire is an antibacterial fiber modified with a chitosan antibacterial agent.

[0049] Example 2

[0050] Refer to Figure 4, this embodiment provides an antibacterial, anti-ultraviolet and breathable composite fabric, which includes an anti-ultraviolet outer layer 1, an antibacterial inner layer 2 and a skin-friendly layer 3. The anti-ultraviolet outer layer 1 is woven from a first yarn, and the antibacterial inner layer 2 is woven from a second yarn 21. The first yarn includes a first anti-ultraviolet core wire and a hydrophilic coating wire wound around the outside of the first anti-ultraviolet core wire; the second yarn 21 includes a second anti-ultraviolet core wire 211 and an antibacterial coating wire 212 wound around the outside of the second anti-ultraviolet core wire; the first anti-ultraviolet core wire and the second anti-ultraviolet core wire are profiled anti-ultraviolet fibers, and the antibacterial coating wire 212 is a hydrophilic fiber. The profiled anti-ultraviolet fibers are hydrophobic chemical fibers.

[0051] A number of ventilation holes 31 are provided on the skin-friendly layer 3, so that sweat or water vapor generated by the skin can be discharged outward through the ventilation holes 31 to keep the skin dry.

[0052] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
