Description

Technical Field

[0001] This utility model relates to the field of functional fabrics and clothing technology, specifically to a novel composite fabric and temperature-regulating clothing. Background Technology

[0002] Traditional fabrics are mostly single-layered, limiting their use. For example, in summer, with large temperature differences between morning, noon, and evening, people who go out early and return late need to wear a light jacket over their short-sleeved shirts for warmth and wind protection; or, when walking outdoors in summer and exposed to intense sunlight, they need to wear sun-protective clothing. With the continuous development of textile technology, how to better adapt textile and apparel products to people's lives is an important direction for the innovative development of textile enterprises. Therefore, composite fabrics, which offer greater versatility in terms of wearing scenarios, have become a current research hotspot in the industry. Compared to single-layer fabrics, composite fabrics combine two or more materials with different properties through methods such as hot-melt bonding, coating bonding, and lamination bonding, achieving significant improvements in fabric performance and quality. This two- or multi-layered structure can better cope with changing climates, enabling multiple uses for one garment, and is convenient and environmentally friendly.

[0003] Currently, in order to achieve the multifunctionality of composite fabrics, functional materials are usually applied to the fabric surface through finishing processes, such as applying a waterproof coating or temperature-regulating material to the fabric layer. This allows the composite fabric to have both waterproof and temperature-regulating functions. However, the performance of the waterproof coating or temperature-regulating material will drop sharply after repeated washing, and it will not achieve the effect of permanent waterproofing or temperature regulation. Utility Model Content

[0004] The primary objective of this invention is to provide a novel composite fabric that addresses the problem of poor functionality and durability in existing composite fabrics.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel composite fabric includes a water-repellent layer, a waterproof and breathable layer, and a temperature-regulating layer arranged sequentially from the outside to the inside, with a mesh-structured adhesive layer between the layers; the water-repellent layer is a water-repellent fabric made of interwoven water-repellent polyester yarns; the waterproof and breathable layer is a TPU waterproof and breathable membrane; and the temperature-regulating layer is a PCM phase change temperature-regulating fabric made of interwoven temperature-regulating fiber yarns.

[0007] Preferably, both the water-repellent fabric and the PCM phase change temperature-regulating fabric are plain weave.

[0008] Preferably, the water-repellent polyester yarn has a specification of 40-60D.

[0009] Preferably, the temperature-regulating fiber yarn has a specification of 60-100S.

[0010] Preferably, the adhesive layer is one or more of polyamide hot melt adhesive, polyester hot melt adhesive, polyethylene hot melt adhesive, and polyesteramide hot melt adhesive.

[0011] Preferably, the overall thickness of the novel composite fabric is 0.5–3 mm, and the weight is 80–200 g / m². 2 .

[0012] The second objective of this invention is to provide a temperature-regulating garment, which aims to improve the problem of poor functionality and durability of existing temperature-regulating garments.

[0013] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] A temperature-regulating garment, wherein all or part of the fabric of the temperature-regulating garment is made of the aforementioned novel composite fabric.

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. The composite fabric in this utility model is composed of three layers of fabric with different functions bonded together by an adhesive layer. The outermost water-repellent layer is a water-repellent fabric, which reduces the absorption of water by the fabric and allows water to be "repelled" on the surface of the fabric. The middle waterproof and breathable layer is a TPU waterproof and breathable membrane, which blocks water droplets while having excellent breathability and moisture permeability. The inner temperature-regulating layer is a PCM phase change temperature-regulating fabric. The phase change material in it can regulate heat and provide a comfortable microclimate environment for the human body. In this way, the composite fabric combines the excellent properties of the three fabrics, has high comfort, and can be used in different weather and ambient temperatures.

[0017] 2. In this utility model, the water-repellent fabric is woven from water-repellent polyester yarn, and the PCM phase change temperature regulating fabric is woven from temperature regulating fiber yarn, so that the composite fabric has good functional durability and still has water-repellent and temperature regulating functions after multiple washes or uses.

[0018] 3. In this utility model, the water-repellent fabric and the PCM phase change temperature regulating fabric are plain weave fabrics. With the addition of the TPU waterproof and breathable membrane, the three-layer structure of the composite fabric is guaranteed to have a flat surface, which increases the bonding strength during the composite process and makes the final composite fabric resistant to peeling after washing.

[0029] Example 1

[0030] Please refer to Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a novel composite fabric, comprising a water-repellent layer 1, a waterproof and breathable layer 2, and a temperature-regulating layer 3 arranged sequentially from the outside to the inside, with a mesh-structured adhesive layer 4 between the layers; the water-repellent layer 1 is a water-repellent fabric, which is woven from water-repellent polyester yarn 11; the waterproof and breathable layer 2 is a TPU waterproof and breathable membrane; the temperature-regulating layer 3 is a PCM phase change temperature-regulating fabric, which is woven from temperature-regulating fiber yarn 31.

[0031] Specifically, the composite fabric in this embodiment consists of three layers of fabric and two bonding layers. The three layers have different functions: the water-repellent layer 1 is a water-repellent fabric that, while maintaining breathability, allows water droplets to form small beads or slide off the garment surface, preventing moisture absorption and making it easier to remove oil and other contaminants. The waterproof and breathable layer 2 is a TPU waterproof and breathable membrane. TPU membranes offer excellent waterproofness, breathability, moisture permeability, and durability. The microporous structure of the TPU membrane allows it to block water droplets while allowing water vapor to pass through. Its high breathability ensures the expulsion of internal moisture, preventing condensation. Furthermore, TPU has excellent abrasion resistance, tear resistance, and aging resistance, extending the fabric's lifespan. Moreover, TPU is a recyclable material, reducing environmental impact. The temperature-regulating layer 3 is a PCM phase-change temperature-regulating fabric that responds to changing temperatures, warming or cooling the wearer as needed.

[0032] The water-repellent fabric is made of water-repellent polyester yarn 11. In this embodiment, the water-repellent polyester yarn 11 is made of polyester yarn through dyeing, dehydration, drying, soaking in waterproofing agent, dehydration, and high-temperature drying. The waterproofing agent is preferably XSY-C616 yarn waterproofing agent. The PCM phase change temperature-regulating fabric is made of temperature-regulating fiber yarn 31. In this embodiment, the temperature-regulating fiber yarn 31 is made by microcapsule spinning, that is, microcapsules containing phase change substances with an average diameter of 1 to 10 μm are mixed with a fiber-forming polymer solution and spun to obtain temperature-regulating fibers, and then the temperature-regulating fibers are spun into yarn. The phase change fibers made by this method have the characteristics of uniform material dispersion, significant temperature-regulating performance, and no leakage during wearing, washing, ironing and other processes.

[0033] In addition, the composite fabric is bonded together by a mesh structure adhesive layer 4 between the layers. The adhesive layer 4 can be one or more of polyamide hot melt adhesive, polyester hot melt adhesive, polyethylene hot melt adhesive and polyesteramide hot melt adhesive. The use of a mesh structure hot melt adhesive ensures both the overall breathability and moisture permeability of the composite fabric, as well as the bonding strength of the fabric, thus ensuring the comfort and durability of the composite fabric.

[0034] Furthermore, both the water-repellent fabric and the PCM phase change temperature-regulating fabric are plain weave fabrics; please refer to [the documentation / reference]. Figure 2As shown, the water-repellent fabric is made of several water-repellent polyester yarns 11 interwoven in alternating layers. Please refer to... Figure 3 As shown, the PCM phase change temperature regulating fabric is made of several temperature regulating fiber yarns 31 interwoven in alternating layers. Specifically, under the premise that the surface of the TPU waterproof and breathable membrane is flat, the fabric structure of the water-repellent fabric and the PCM phase change temperature regulating fabric is plain weave, which ensures that the three layers of the composite fabric are all flat surfaces, increases the bonding strength during the composite process, and makes the final composite fabric resistant to peeling after washing.

[0035] Furthermore, the specifications of the water-repellent polyester yarn 11 are 40-60D, the specifications of the temperature-regulating fiber yarn 31 are 60-100S, the overall thickness of the new composite fabric is 0.5-3mm, the weight is 80-200g / m2, and the composite fabric is relatively lightweight and comfortable overall.

[0036] Example 2

[0037] Please refer to Figure 4 As shown, this embodiment provides a temperature-regulating garment, in which all or part of the fabric is made of the novel composite fabric described in Example 1, giving the temperature-regulating garment permanent waterproof, breathable, moisture-wicking, and temperature-regulating functions.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
