Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a flame-retardant and mosquito-repellent double-layer fabric, and more particularly to a flame-retardant and mosquito-repellent double-layer fabric for forest protection in the wild. Background Technology

[0002] In modern society, the functional requirements of textiles are becoming increasingly diverse. For those working in the forest (such as forestry workers and field protection workers), who face risks such as mosquito bites and fire hazards, it is essential to wear protective textiles that combine mosquito repellency and flame retardancy.

[0003] Currently, mosquito-repellent fabrics used for forest protection in the wild mostly achieve mosquito repellency by spraying or impregnating with chemical mosquito repellents containing ingredients such as DEET. Although the effect is significant, it is irritating to the skin, and long-term contact can easily cause allergies. Moreover, the mosquito repellent is easily washed off after multiple washes, and the mosquito-repellent effect is greatly reduced. Flame-retardant fabrics are often treated with halogenated and phosphorus-based flame retardants. Halogenated flame retardants have good flame-retardant effects, but they release toxic and harmful gases when burning, which harm the environment and human health. Phosphorus-based flame retardants have insufficient durability, and their flame-retardant performance decreases after multiple washes or long-term use. In addition, flame-retardant treatment will make the fabric feel stiff and reduce wearing comfort. Existing attempts to combine mosquito-repellent and flame-retardant functions in the preparation of fabrics often involve mosquito-repellent treatment first, followed by flame-retardant treatment, or vice versa. From the perspective of mechanism of action, mosquito-repellent treatment usually introduces chemical mosquito repellents on the surface of the fabric. Its main function is to interfere with mosquito perception and achieve the purpose of repelling mosquitoes. Flame-retardant treatment uses flame retardants to change the combustion characteristics of the fabric, such as inhibiting the combustion reaction and reducing heat transfer. When mosquito repellent and flame retardant are applied to fabrics in a simple sequential manner, the chemical binding sites formed on the fabric fiber surface by the two agents can easily compete. For example, the coating layer formed by the mosquito repellent on the fabric surface may hinder the effective binding of the flame retardant to the fiber, preventing the flame retardant from fully exerting its combustion-inhibiting function and resulting in unstable flame retardant performance. Simultaneously, the high temperatures and chemical reagents during the flame retardant treatment process may damage the chemical structure of the mosquito repellent, causing the active ingredients to decompose or detach from the fabric surface, significantly weakening the mosquito-repellent effect. In actual use, this lack of synergy becomes more pronounced after multiple washes; the two functions diminish more rapidly with each wash, failing to provide a consistently stable and reliable protection for the user. This clearly demonstrates that existing treatment methods struggle to achieve effective synergy between mosquito repellency and flame retardancy. Furthermore, the overall fabric performance (such as comfort and durability) remains unimproved. Therefore, there is an urgent need to develop a fabric that effectively repels mosquitoes, possesses flame retardant properties, and significantly improves wearing comfort to meet the needs of specific scenarios such as outdoor forest work. Summary of the Invention

[0004] This application provides a flame-retardant and mosquito-repellent double-layer fabric, which solves the problems of poor mosquito-repellent effect, unstable flame-retardant performance, and poor comfort of existing outdoor forest protection fabrics. The specific solution is as follows:

[0005] A flame-retardant and mosquito-repellent double-layer fabric includes: a double-woven outer layer and a mesh inner layer;

[0006] Furthermore, the outer and inner layers have junctions between the outer layer weft yarns and the inner layer warp yarns.

[0007] Furthermore, the warp and weft yarns of the outer and inner layers are configured in a 1:1 ratio.

[0008] Furthermore, the outer layer and the inner layer have:

[0009] In a double-layer structure consisting of an outer and inner layer, the outer layer warp yarns need to be fully lifted when weaving the inner layer, and the weft yarns at the joints are the outer layer weft yarns and the inner layer weft yarns.

[0010] The interlacing of warp yarns forms the joints, which are covered by the floating threads in the surface warp direction, making the fabric crisp, beautiful and without any visible seams.

[0011] Furthermore, the mesh structure includes:

[0012] The inner warp and weft yarns are combined using a plain weave and a double plain weave structure. Because the adjacent plain weave yarns interweave multiple times and the weave points are opposite, the float yarns of the double plain weave structure are sandwiched in the plain weave. Therefore, the float yarns shrink and are squeezed up by the plain weave yarns on both sides, thus forming a mesh.

[0013] Furthermore, the outer warp yarn is made of inherently flame-retardant yarn, the outer weft yarn is made of inherently flame-retardant yarn with mosquito-repellent function, and both the inner warp and weft yarns are made of moisture-absorbing and antibacterial spacer yarn.

[0014] Furthermore, the inner layer yarn is a moisture-absorbing and antibacterial spacer yarn, comprising a moisture-absorbing functional zone and an antibacterial functional zone. The moisture-absorbing functional zone is spun from one or two of the following fibers: cotton fiber, flame-retardant viscose fiber, lyocell fiber, and modal fiber; the antibacterial functional zone is spun from one or two of the following fibers: bamboo fiber, hemp fiber, polyester fiber, seaweed fiber, and chitin fiber.

[0015] Furthermore, the double-layer structure formed by the outer and inner layers is designed according to the porosity by adjusting the number of yarn cycles in the fabric structure and the arrangement ratio of warp and weft yarns in the outer and inner layers to adjust the mesh size.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] This application provides a fabric that effectively repels mosquitoes, has flame-retardant properties, and significantly improves wearing comfort by setting the comfort layer as the inner layer and setting the flame-retardant and mosquito-repellent layer as the outer layer. The flame-retardant and mosquito-repellent layer employs a double-layer weave, enabling effective synergy between mosquito-repellent and flame-retardant functions and avoiding mutual interference. The long floats in the outer warp effectively cover the junctions between the outer weft yarn and the inner warp yarn, with most of the weft yarns hidden beneath the outer warp yarns, protecting the mosquito-repellent function, enhancing its durability, and improving the fabric's longevity. The comfort layer utilizes a mesh structure with a large specific surface area and porosity, allowing for rapid absorption of sweat from the skin's surface and diffusion of sweat to the outside through the mesh openings, accelerating sweat evaporation and keeping the skin dry. Furthermore, the textured three-dimensional structure formed by the inner mesh layer makes the skin-contact layer softer, reducing the contact area and friction with the skin, further enhancing wearing comfort. The flame-retardant and mosquito-repellent layer and the comfort layer are joined in a single weaving process, improving the fabric's comfort and durability, ensuring the stability of the fabric structure and the overall performance.

[0018] In this application, the warp yarn of the surface fabric is made of inherently flame-retardant fiber, and the weft yarn is made of inherently flame-retardant yarn with mosquito-repellent function, so as to achieve an organic combination and synergistic effect of mosquito-repellent and flame-retardant functions.

[0019] In this application, both the warp and weft yarns of the inner layer fabric are made of moisture-wicking and antibacterial spacer yarn, which improves breathability and provides a cool and comfortable wearing experience. Attached Figure Description

[0040] like Figures 1-2 The present invention discloses a flame-retardant and mosquito-repellent double-layer fabric, comprising: a double-woven outer layer 100 and a mesh inner layer 200; wherein the outer layer 100 and the inner layer 200 have junction points between the outer layer weft yarn and the inner layer warp yarn. Specifically, the outer layer 100 adopts a double-woven warp structure, and the inner layer 200 adopts a mesh structure. The warp and weft yarn ratio of the outer layer and the inner layer is configured in a 1:1 ratio. The warp yarn of the outer layer is an inherently flame-retardant yarn, and the weft yarn of the outer layer is an inherently flame-retardant yarn with mosquito-repellent function, forming a flame-retardant and mosquito-repellent layer. Both the warp and weft yarns of the inner layer adopt moisture-absorbing and antibacterial spacer yarn 900, forming a comfort layer. The inner layer yarn of the comfort layer consists of a moisture-absorbing functional area 700 and an antibacterial functional area 800.

[0041] In the above description, the outer layer 100 and the inner layer 200 have a junction formed by the outer layer weft yarn and the inner layer warp yarn. Specifically, as shown... Figures 3-7As shown, the warp and weft yarns of the outer and inner layers are arranged in a 1:1 ratio, with a yarn repeat count of 16. The warp yarns are: 1, 3, 5, 7, 9, 11, 13, 15 (inner layer warp yarns), and 2, 4, 6, 8, 10, 12, 14, 16 (outer layer warp yarns). The weft yarns are: 1, 3, 5, 7, 9, 11, 13, 15 (inner layer weft yarns), and 2, 4, 6, 8, 10, 12, 14, 16 (outer layer weft yarns). "X" and "*" indicate warp interlacing points. "X" represents the warp interlacing point in the double-layer structure, and "*" represents the warp interlacing point formed when all the outer layer warp yarns are lifted during the weaving of the inner layer. "S" represents the junction point between the outer layer weft yarn and the inner layer warp yarn.

[0042] In the above, the surface layer uses a double-layered structure, and the inner layer uses a mesh structure, such as... Figure 3 As shown, warp and weft yarns 1, 3, 5, 7 and 9, 11, 13, 15 are combined using a combination of plain and double plain weave. Because the adjacent plain weave yarns interweave multiple times and the weave points are opposite, yarns 7 and 9 are separated from each other. The floats of the plain weave are sandwiched in the plain weave, which causes the floats to shrink and be squeezed up by the plain weave yarns on both sides, causing yarns 1, 3, 5, 7 and 9, 11, 13, 15 to gather together and form a mesh between yarns 7 and 9.

[0043] It should be noted that after the surface and inner layers are interwoven in the manner described above, refer to... Figure 1 As shown, it forms warp points 300 for the outer warp yarns, warp points 400 for the inner warp yarns, weft points 500 for the outer warp yarns, and weft points 600 for the inner warp yarns on the surface of the double-layer fabric.

[0044] In the above, the interlacing method of using "S" as the junction point of the outer layer weft yarn and the inner layer warp yarn can perfectly cover the junction point through the floating long thread in the outer layer warp direction, making the fabric crisp, beautiful and without any exposed spots.

[0045] In the above, the outer warp yarn is made of inherently flame-retardant yarn, the outer weft yarn is made of inherently flame-retardant yarn with mosquito-repellent function, and both the inner warp and weft yarns are made of moisture-absorbing and antibacterial spacer yarn. The inner yarn is made of moisture-absorbing and antibacterial spacer yarn, which includes a moisture-absorbing functional area and an antibacterial functional area. The moisture-absorbing functional area is a mixture of cotton fiber and flame-retardant viscose fiber in a 5:5 ratio; and / or the antibacterial functional area is a mixture of bamboo fiber and seaweed fiber in a 6:4 ratio. The two raw materials are spun into roving and then spun through Siro spinning to form the moisture-absorbing and antibacterial spacer yarn.

[0046] In the above, the inner layer yarn uses a moisture-absorbing and antibacterial spacer yarn, which is composed of two components. One component is selected from one or two fibers such as cotton fiber, flame-retardant viscose fiber, lyocell fiber, and modal fiber; the other component is selected from one or two fibers such as bamboo fiber, hemp fiber, polyester fiber, seaweed fiber, and chitin fiber. The two raw materials are spun into rovings separately, and then formed into a moisture-absorbing and antibacterial spacer yarn through Sirospinning.

[0047] In the above-described double-layer fabric, the inner layer has a uniformly arranged mesh, and the regular aggregation of yarns in the weave creates tiny, regular bumps on the inner layer, enhancing the fabric's three-dimensionality, reducing the contact area with human skin, and enabling rapid absorption of sweat from the skin's surface, carrying it to the surface and dissipating it into the air, resulting in a cool and comfortable wearing experience. Tests on the flame-retardant, mosquito-repellent, and moisture-wicking properties of the flame-retardant and mosquito-repellent double-layer fabric described in this application demonstrate that it possesses excellent flame-retardant, mosquito-repellent, and wearing comfort properties.

[0048] Specifically, flame retardant performance: After washing the flame retardant mosquito repellent double-layer fabric described in this application 50 times, its flame retardant performance was tested according to GB / T5455-2014. The results showed that the warp damage length of the fabric was 80mm, the weft damage length was 82mm, the warp and weft afterflame time was 0s, and the smoldering time was less than 2s, which met the flame retardant Class A requirements.

[0049] Mosquito repellency: After washing the flame-retardant and mosquito-repellent double-layer fabric described in this application 50 times, its mosquito knockdown effect was tested according to GB / T 30126-2013. The knockdown rate was 86.5%, which shows good knockdown effect and the mosquito repellency rating is B. The fabric was made into a 50cm×50cm sample and tested in a simulated mosquito environment. Within 10 minutes, the mosquitoes stayed on the fabric surface for no more than 1 minute and no bites were observed, showing a significant mosquito repellency effect.

[0050] Moisture absorption and quick-drying performance: After washing the flame-retardant and mosquito-repellent double-layer fabric described in this application 50 times, the moisture absorption and quick-drying performance was tested according to GB / T21655.1-2008 "Evaluation of moisture absorption and quick-drying properties of textiles - Part 1: Single-item combination test method". The water absorption rate was 105%, the drip diffusion time was 3.2s, the wicking height was 108mm, the evaporation rate was 0.38g / h, and the moisture permeability was 9545.0g / m³. 2 •d, All test indicators met the standard requirements. Through wearing tests, 10 volunteers wore the fabric in an outdoor environment for 4 hours. They reported that their skin remained dry and there was no stuffiness during the wearing process. The fabric's micro-protrusion design reduced the contact area with the skin, quickly absorbed and dissipated sweat, and made it comfortable to wear.

[0051] In addition to the above-disclosed features, this application further includes: the outer fabric uses inherently flame-retardant fibers in the warp direction and inherently flame-retardant yarns with mosquito-repellent properties in the weft direction, giving the entire fabric inherently flame-retardant properties. Furthermore, instead of using inherently flame-retardant yarns with mosquito-repellent properties in the warp direction, different materials are configured in the warp and weft directions to avoid damage to the mosquito-repellent fibers caused by repeated interlacing of the warp yarns, maximizing the effectiveness and saving costs, thus achieving an organic combination and synergistic effect of mosquito-repellent and flame-retardant functions. The inner fabric uses a combination of skin-friendly and comfortable natural fiber materials and inherently antibacterial and cool polyester fiber materials, employing moisture-wicking and antibacterial interlayer yarns. This gives the fabric's skin-friendly layer excellent moisture absorption, breathability, and natural antibacterial properties, a soft and cool touch, and the ability to quickly absorb sweat from the skin surface and dissipate it into the air, providing a refreshing and comfortable wearing experience.

[0052] The outer layer uses a double-weave structure, while the inner layer uses a mesh structure. The warp and weft yarns of the outer and inner layers are configured in a 1:1 ratio. The outer and inner layers are connected in one piece through a weaving process, ensuring the stability of the fabric structure and the overall performance. The long floats in the warp direction of the outer layer effectively cover the junctions between the weft yarns of the outer layer and the warp yarns of the inner layer, and cover most of the weft yarns under the warp yarns of the outer layer, protecting the weft yarns and enhancing the durability of mosquito repellency. The inner layer uses a mesh structure, forming a double-layer fabric with the outer layer. On the one hand, the inner layer has evenly arranged mesh; on the other hand, the regular aggregation of yarns in the weave cycle creates a small and regular distribution of ridges in the inner layer, enhancing the three-dimensionality of the fabric, reducing the contact area with human skin, and improving comfort.
