Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, specifically a waterproof and antibacterial composite fabric. Background Technology

[0002] Among numerous functional requirements, waterproofing is an extremely important function in modern textile fabrics. Waterproof fabrics can effectively block external liquid water, thus protecting the wearer from rain, stains, and other aggressors, playing a vital role in outdoor sports, specialized work, and daily life. Currently, various waterproof fabric technologies exist on the market, such as those that impart waterproofing properties through denser fabric structures, coatings, and other methods.

[0003] However, most waterproof fabrics currently available suffer from poor breathability. To achieve waterproofing, breathability is often sacrificed, making it difficult for moisture to escape. Wearing waterproof but non-breathable fabrics for extended periods causes body moisture and heat to accumulate inside the garment, leading to stuffiness and discomfort. This stuffiness is particularly pronounced in humid or active environments, severely impacting the wearing experience.

[0004] More importantly, the hot and humid environment inside clothing provides favorable conditions for bacterial growth and reproduction. Sweat, dead skin cells, and other organic matter accumulate inside the damp fabric, becoming a nutrient source for bacteria. Excessive bacterial growth not only produces odors and affects the hygiene of clothing, but can also cause skin itching, allergies, and other problems, posing a potential threat to human health. This is especially true in specialized applications such as medical and outdoor adventure, where there are even higher requirements for the antibacterial properties of fabrics.

[0005] Therefore, how to balance the waterproof and breathable properties of waterproof fabrics while simultaneously giving them antibacterial functions has become a pressing technical challenge in the field of functional fabrics. Utility Model Content

[0006] In order to overcome the shortcomings of existing waterproof fabrics, such as poor breathability, stuffiness and easy bacterial growth after long-term wear, this utility model provides a waterproof and antibacterial composite fabric. The aim is to provide a composite fabric that can effectively waterproof, maintain good breathability, and also has antibacterial properties, so as to meet people's demand for high-quality and multifunctional textile products.

[0007] The technical solution of this utility model is achieved as follows:

[0008] A waterproof and antibacterial composite fabric includes: a base fabric woven from antibacterial yarns; a high-density waterproof fabric disposed on one side of the base fabric; multiple breathable partitions are spaced apart on the high-density waterproof fabric, and a perforated frame is fixed inside each perforated partition. The perforated frame has an O-shaped frame structure, and snap-fit ​​grooves are provided on both side walls of the perforated frame. The edge of the high-density waterproof fabric is snapped into the snap-fit ​​grooves; a waterproof and breathable membrane is covered on the side of the perforated frame away from the base fabric.

[0009] Furthermore, in order to achieve the elastic support function of the hollow frame, the hollow frame includes: an upper plate, a lower plate and an elastic element, wherein the elastic element is disposed between the upper plate and the lower plate and is used to support the upper plate.

[0010] Furthermore, to ensure complete coverage and effective waterproofing of the waterproof and breathable membrane, the waterproof and breathable membrane completely covers the side of the perforated frame away from the base fabric and extends to the surface of the high-density waterproof fabric.

[0011] Furthermore, in order to achieve the antibacterial properties of the fabric, the antibacterial yarn is composed of multiple spirally wound silver ion fibers, copper ion fibers, and quaternary ammonium salt modified cotton fibers.

[0012] Furthermore, to ensure the strength and comfort of the base fabric, the warp density of the base fabric is 100 threads / cm and the weft density is 80 threads / cm.

[0013] Furthermore, in order to achieve the waterproof performance and thinness of the high-density waterproof fabric, the areal density of the high-density waterproof fabric is 150-250 g / m².

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention cleverly combines the waterproof performance of a high-density waterproof fabric with breathable partitions, and incorporates a perforated frame and a waterproof and breathable membrane within these partitions. This effectively improves the breathability of the fabric while maintaining its waterproof properties, overcoming the poor breathability of existing waterproof fabrics. The perforated frame supports the breathable partitions, preventing the ventilation channels from closing, while the waterproof and breathable membrane ensures the waterproofness of the breathable areas, achieving a balance between waterproofing and breathability.

[0016] Meanwhile, the base fabric is woven with antibacterial yarn, which can effectively inhibit the growth and reproduction of bacteria, improve the hygiene performance of the fabric, and reduce odor and skin discomfort caused by bacteria. It is especially suitable for application areas with high hygiene requirements.

[0017] The openwork frame structure effectively supports the breathable partition, ensuring its structural stability and shape regularity, and enhancing the overall strength and durability of the fabric. It also imparts a degree of elasticity to the breathable partition, giving the fabric better dynamic adaptability and improving wearing comfort and flexibility. Attached Figure Description

[0027] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0028] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] As attached Figure 1-3 The waterproof and antibacterial composite fabric shown includes: a base fabric 1, which is woven from antibacterial yarn 11; and a high-density waterproof fabric 2, which is disposed on one side of the base fabric 1.

[0030] Multiple breathable partitions 21 are spaced apart on the high-density waterproof fabric 2. A hollow frame 3 is fixed inside the breathable partition 21. The hollow frame 3 has an O-shaped frame structure, and a snap-fit ​​groove 31 is opened on both side walls of the hollow frame 3. The edge of the high-density waterproof fabric 2 is snapped into the snap-fit ​​groove 31.

[0031] The side of the hollow frame 3 away from the base fabric 1 is covered with a waterproof and breathable membrane 32.

[0032] In some embodiments, the hollow frame 3 includes an upper plate 33, a lower plate 35 and an elastic member 34, the elastic member 34 being disposed between the upper plate 33 and the lower plate 35 for supporting the upper plate 33.

[0033] In some embodiments, the waterproof and breathable membrane 32 completely covers the side of the cutout frame 3 away from the base fabric 1 and extends to the surface of the high-density waterproof fabric 2.

[0034] In some embodiments, the antibacterial yarn 11 is composed of multiple spirally wound silver ion fibers 111, copper ion fibers 112, and quaternary ammonium salt modified cotton fibers 113.

[0035] In some embodiments, the warp density of the base fabric 1 is 100 threads / cm and the weft density is 80 threads / cm.

[0036] In some embodiments, the areal density of the high-density waterproof fabric 2 is 150-250 g / m².

[0037] The function of the perforated frame 3 is to artificially create a three-dimensional breathable channel on the high-density waterproof fabric 2. While the high-density waterproof fabric 2 has breathable partitions 21, the fabric's softness can cause these partitions to close easily during wear or under stress, significantly reducing breathability. The perforated frame 3 expands the space around the breathable partitions 21, ensuring the breathable channel remains open. Furthermore, the waterproof breathable membrane 32 is typically made of thin and fragile material. Directly covering it with the breathable partitions 21 would easily damage it due to friction, pulling, or other external forces. The perforated frame 3, as a supporting structure, provides a stable base for the waterproof breathable membrane 32, reducing deformation and damage, extending its lifespan, and ensuring stable breathability. The perforated frame 3 creates a space where air can circulate freely. When outside air needs to enter the garment, or when humid and hot air inside the garment needs to escape, the perforated frame 3 reduces airflow resistance, improving the overall breathability of the fabric.

[0038] Directly creating perforations in the high-density waterproof fabric 2 as breathable barriers 21 can easily lead to stress concentration at the edges of the perforations, reducing the fabric's tear resistance. The addition of the perforated frame 3 effectively reinforces the edges of the breathable barrier 21, dispersing stress and increasing the strength of the breathable barrier area, making the fabric more durable. The perforated frame 3, with its upper plate 33, lower plate 35, and elastic element 34, provides the breathable barrier 21 with a certain degree of elastic cushioning. When the fabric is subjected to external forces such as compression or stretching, the elastic element 34 can deform, absorbing some of the force and reducing the impact on other parts of the fabric.

[0039] Example 1

[0040] The base fabric 1 is made of a blended yarn of cotton and polyester fibers, with a blend ratio of 60% cotton and 40% polyester. Cotton fibers provide good moisture absorption and skin-friendliness, while polyester fibers improve the strength and abrasion resistance of the base fabric 1.

[0041] The antibacterial yarn 11 is made by spirally winding silver ion fiber 111, copper ion fiber 112 and quaternary ammonium salt modified cotton fiber 113. The above three antibacterial fibers are mixed in a volume ratio of 1:1:1 and spun into an antibacterial yarn 11 with a count of 40 through a three-component composite spinning technology.

[0042] High-density waterproof fabric 2 is made of high-density polyester filament fabric with a yarn specification of 75D / 72F. The fabric structure is plain weave, with a warp density of 150 threads / cm and a weft density of 120 threads / cm. After weaving, high-density waterproof fabric 2 undergoes an environmentally friendly PU waterproof finishing process.

[0043] The waterproof and breathable membrane 32 is made of ePTFE microporous membrane with a thickness of 0.02mm and a pore size of 0.2μm.

[0044] The hollow frame 3 is made of TPU elastomer material. TPU material has good elasticity, wear resistance and weather resistance, and the elastic parts 34 and other structures are integrally formed by 3D printing.

[0045] The base fabric 1 is woven on a rapier loom using a plain weave. The high-density waterproof fabric 2 is woven on a high-speed water jet loom using a plain weave.

[0046] Using a laser cutter, the breathable partitions 21 are precisely cut out on the high-density waterproof fabric 2 according to the preset size and arrangement. The 3D-printed hollow frame 3 is glued to the base fabric 1, and then the edges of the high-density waterproof fabric 2 are manually inserted into the dovetail-shaped locking grooves 31 of the hollow frame 3 to achieve a firm fixation between the hollow frame 3 and the high-density waterproof fabric 2.

[0047] Finally, the waterproof and breathable membrane 32 is cut into a long piece slightly larger than the perforated frame 3. Then, a hot-pressing composite process is used to cover the side of the perforated frame 3 away from the base fabric 1 with the waterproof and breathable membrane 32. The hot-pressing temperature is 140℃, the pressure is 0.2MPa, and the hot-pressing time is 15 seconds. During the hot-pressing process, the edge of the waterproof and breathable membrane 32 is thermally bonded to the surface of the high-density waterproof fabric 2, achieving a waterproof seal.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
