[0023] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0025] Figure 1 This is a schematic diagram of the structure of a windproof and warm multi-layer fabric provided in this application. Figure 1 As shown, the windproof and warm multi-layer fabric provided in this embodiment includes a surface layer 101 , a middle layer 102 and a polar layer 103 .
[0026] The upper surface of the surface layer 101 is provided with an intermediate layer 102, and the intermediate layer 102 is provided with a polar layer 103. The intermediate layer 102 and the polar layer 103 are prepared at a set fineness ratio to achieve the effect of windproof and warmth preservation; the intermediate layer 102 is used to increase the strength and compactness of the fabric.
[0027] In a possible implementation, the surface layer 101 may be made of a fabric with high density and good windproof performance, such as a high-count nylon or polyester material, to ensure that the surface is smooth and can effectively resist wind.
[0028] The middle layer 102 is an auxiliary reinforcement layer, and the single filament fineness of the auxiliary reinforcement layer is a fully drawn filament with a fineness greater than 1 dtex (Dtex) to ensure that it has sufficient strength and durability.
[0029] The polarization layer 103 is made of ultra-fine fibers with a single filament fineness of less than 0.5 dtex, and fine fluff is formed on the surface thereof through a polarization process to enhance the warmth retention performance.
[0030] The surface layer 101, the middle layer 102 and the polar layer 103 can be combined together by an integral weaving method to ensure a close fit between the layers, thereby forming a multi-layer fabric with windproof and warmth-keeping functions.
[0031] In a possible implementation, the yarn fineness of the middle layer 102 is set to 0.2 to 0.5 times the yarn fineness of the polar layer 103. For example, if the yarn fineness of the polar layer 103 is 2 dtex, the yarn fineness of the middle layer 102 is set to 0.4 to 1 dtex. In practical applications, the thermal insulation performance, air permeability and hand feel of the fabric under different fineness ratios can be tested experimentally to determine the most appropriate fineness ratio. The fineness ratio is not specifically limited in this embodiment.
[0032] In a possible implementation, the thermal stability of the fabric may be controlled by controlling the boiling water shrinkage of the middle layer 102 and the polar layer 103 .
[0033] Specifically, when controlling the boiling water shrinkage of the middle layer 102, the heat treatment process of the fibers of the middle layer 102 can be adjusted, for example, by using a heat setting process or a heat stretching process to control the boiling water shrinkage to be greater than 10% to ensure the dimensional stability of the fabric after washing.
[0034] Specifically, when controlling the boiling water shrinkage of the polar layer 103, the boiling water shrinkage of the polar layer 103 can be controlled within a range of less than 5% by selecting a fiber material with lower heat shrinkage or by a proper heat treatment process.
[0035] In one possible implementation, the yarn of the middle layer 102 can be made of graphene fiber. In this way, the excellent thermal conductivity and antistatic properties of graphene fiber can be used to improve the warmth retention and wearing comfort of the fabric, and the problem of fabric pilling can also be reduced.
[0036] Optionally, the graphene fibers can be combined with other fiber materials of the polar layer 103 through a specific process to form a multi-layer fabric with enhanced warmth retention and antistatic functions.
[0037] The windproof and warm multi-layer fabric of this embodiment is provided with a surface layer 101, and an intermediate layer 102 is provided on the upper surface of the surface layer 101, and a polar layer 103 is provided on the intermediate layer 102; the intermediate layer 102 and the polar layer 103 are prepared at a set fineness ratio; the intermediate layer 102 is used to increase the strength and compactness of the fabric. According to this embodiment, the intermediate layer 102 and the polar layer 103 are prepared at a set fineness ratio. Compared with the general fabric structure, there is no high shrinkage yarn of the middle auxiliary reinforcement layer. This high shrinkage yarn has a fully drawn yarn (Fully Drawn Yarn, FDY) that makes the surface layer denser and the intermediate layer thinner, so that the gap between the polar layer and the surface layer is larger, and the fabric is lighter and more heat-insulating. At the same time, the yarn of the intermediate layer adopts graphene fiber, which has good antistatic properties and can reduce the pilling phenomenon caused by static electricity in the polar layer during friction. Therefore, this embodiment can provide a windproof and warm multi-layer fabric while improving the anti-pilling, tearing strength, warmth retention and comfort performance of the fabric.
[0038] Figure 2 The present invention provides a flow chart of a method for preparing a windproof and warm multi-layer fabric. Figure 2 As shown, the method of this embodiment may include the following steps 2100 to 2200:
[0039] Step 2100: Prepare an intermediate layer 102 on the surface layer 101, wherein the yarn fineness of the intermediate layer 102 is 0.2 to 0.5 times the yarn fineness of the polar layer 103, the single filament fineness of the intermediate layer 102 is a fully drawn yarn greater than 1 dtex, and the boiling water shrinkage is greater than 10%.
[0040] For example, assuming that the yarn fineness of the polar layer 103 is 2 dtex, the yarn fineness of the middle layer 102 is set to 0.4 dtex to 1 dtex. In practical applications, the thermal insulation performance, air permeability and hand feel of the fabric under different fineness ratios can be tested experimentally to determine the most appropriate fineness ratio. This embodiment does not specifically limit the fineness ratio.
[0041] The single filament fineness of the middle layer 102 is greater than 1 dtex, which can ensure that it has sufficient strength and durability. The boiling water shrinkage rate is greater than 10%, which can ensure the dimensional stability of the fabric after washing.
[0042] The yarn of the middle layer 102 may be made of graphene fiber to achieve the purpose of anti-static and pilling reduction.
[0043] Step 2200: Prepare a polar layer 103, wherein the polar layer 103 has a single yarn fineness of less than 0.5 dtex of a textured yarn and a boiling water shrinkage of less than 5%.
[0044] The polarization layer 103 is made of ultra-fine fibers with a single-filament fineness of less than 0.5 dtex, and fine fluff is formed on the surface thereof through a polarization process to enhance the warmth-keeping performance.
[0045] The boiling water shrinkage of the polar particle layer 103 can be controlled within a range of less than 5% by selecting a fiber material with lower heat shrinkage or by a proper heat treatment process.
[0046] Step 2300: The middle layer 102 and the polar layer 103 are woven into one piece through a specific process to form a multi-layer fabric.
[0047] The specific process for integrally weaving the middle layer 102 and the polar layer 103 can be selected according to actual needs, and this embodiment does not specifically limit the specific process.
[0048] According to the preparation method of the windproof and warm multi-layer fabric of this embodiment, the middle layer 102 is prepared on the surface layer 101, the yarn fineness of the middle layer 102 is 0.2 to 0.5 times the yarn fineness of the polar layer 103, the monofilament fineness of the middle layer 102 is a fully drawn yarn greater than 1 dtex, and the boiling water shrinkage is greater than 10%; the polar layer 103 is prepared, the monofilament fineness of the polar layer 103 is less than 0.5 dtex of the elastic yarn, and the boiling water shrinkage is less than 5%; and then the middle layer 102 and the polar layer 103 are woven as a whole through a specific process to form a multi-layer fabric. In this way, by preparing the middle layer 102 and the polar layer 103 with a set fineness ratio, it is possible to provide a windproof and warm multi-layer fabric while improving the anti-pilling, tearing strength, warmth and comfort performance of the fabric.
