Description

Technical Field

[0001] The utility model relates to a warp knitted fabric, in particular to a light, thin, breathable, quick-drying and differentiated moisture-conducting warp knitted fabric. Background Art

[0002] With the development of the times, consumers' requirements for clothing are no longer limited to aesthetics, and their demand for functionality is increasing. In terms of sports fabrics, how to quickly discharge sweat generated during exercise so that the wearer does not sweat and stays dry for a long time is a major development direction of sports fabrics.

[0003] Currently, there are three common methods to achieve unidirectional moisture conduction in fabrics: 1. Use functional yarns or yarns with different water conduction capabilities; 2. Use a double-layer structure to make the two sides of the fabric have different water conductivities; 3. Perform post-processing such as printing and laminating on the fabric. For example:

[0004] Patent CN205529306U, "A one-way moisture-conducting functional fabric", discloses a one-way moisture-conducting functional fabric, comprising a body-contacting layer and a surface layer, the surface layer being woven from hydrophilic fibers. The body-contacting surface is composed of hydrophobic polypropylene fibers, which make up 75% of the body-contacting surface area, and hydrophilic fibers, which make up 25% of the body-contacting surface area. When the body-contacting layer sweats violently, the hydrophobic polypropylene fibers act as a wicking effect to discharge sweat while the hydrophilic fibers absorb the sweat, achieving the one-way moisture-conducting function.

[0005] Patent CN109972275A, "Knitted fabric with unidirectional moisture conduction, double-sided anisotropy, moisture absorption and quick-drying functions and its preparation method", discloses that the front side of the fabric is woven with hydrophilic yarn to form a hydrophilic evaporation surface, and the back side of the fabric is woven with siro composite yarn to form a moisture conduction surface, so that the front and back sides of the fabric have different hydrophilic and hydrophobic properties, thereby achieving the unidirectional moisture conduction function.

[0006] Patent CN110373902A, "A method for preparing a three-dimensional dual-unidirectional moisture-conducting fabric," discloses a method of printing a hydrophobic finishing agent on the entire bottom of one side and adjusting the printing thickness so that water can be transferred from the hydrophobic surface to the hydrophilic surface. All areas of the hydrophobic surface can be conductive and the hydrophobic surface is kept absolutely dry, making full use of the entire fabric while also considering its horizontal diffusion to achieve the purpose of moisture absorption and quick drying.

[0007] However, using yarns with moisture-wicking and quick-drying properties or using post-finishing methods to achieve unidirectional moisture-wicking properties has limited durability, gradually weakening or even disappearing with repeated washings, and is not environmentally friendly. While double-layer or multi-layer fabrics offer better unidirectional moisture-wicking properties, they lack the advantages of single-layer fabrics in thickness and weight, and have significant limitations in terms of breathability and wearing comfort.

[0008] At present, the fabrics with unidirectional moisture conduction function can be summarized in principle as achieving the unidirectional moisture conduction effect by creating a humidity gradient. Therefore, the gram weight of the fabric has a great influence on the unidirectional moisture conduction function. The smaller the gram weight of the fabric, the thinner its thickness, and the shorter the transmission distance of sweat in the vertical direction of the fabric, which is not conducive to the expansion of the humidity gradient. Summary of the Invention

[0009] In order to solve the above technical problems, the present invention provides a light, thin, breathable, quick-drying, differentiated moisture-conducting warp-knitted fabric that improves wearing comfort.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A lightweight, breathable, quick-drying, differentiated moisture-conducting warp-knitted fabric comprises a fabric body, the fabric body being woven from at least two or more yarns, including yarn Y1 and yarn Y2. The fabric body comprises a clothing surface and a skin-contacting surface, the skin-contacting surface being an extension line layer, and the clothing surface being a coil and column layer. Yarn Y1 is woven to form the skin-contacting surface of the fabric body, and yarn Y2 is woven to form the clothing surface of the fabric body. The fineness of yarn Y1 is less than 40D, and the fineness of yarn Y2 is less than 60D. The ratio of the diameter D1 of yarn Y1 to the diameter D2 of yarn Y2 is ≤0.7, and the water-conducting capacity LpY2 of yarn Y2 and yarn Y1 is: LpY1≥1.8. The extension line of yarn Y1 spans 2 to 8 stitches, which is 1 to 4 stitches more than the span of yarn Y2. The gram weight of the fabric body is ≤75 GSM.

[0012] The yarn Y1 and the yarn Y2 are both non-elastic yarns.

[0013] The yarn Y1 and the yarn Y2 are non-elastic yarns made of the same material or non-elastic yarns made of different materials.

[0014] The extension line of the yarn Y1 has a span of 2 or 3 more stitches than that of the yarn Y2.

[0015] The fabric body is a porous fabric or a non-porous fabric.

[0016] The skin-contacting surface and the clothing surface are respectively of warp-bend, warp-pile, warp-plain or variable structure woven in the same direction or in the opposite direction, and the skin-contacting surface and the clothing surface are of the same structure or different structures.

[0017] The yarn Y1 and the yarn Y2 are filaments or staple fibers, preferably polyester fibers.

[0018] The fabric body is an open structure or a closed structure.

[0019] An elastic connecting layer is provided in the fabric body, and the elastic connecting layer connects the clothing surface and the skin-contacting surface respectively.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] Two yarns with different water-conducting abilities are used to weave the garment surface and the skin-contacting surface of the fabric, respectively. This results in different water conductivities on the garment surface and the skin-contacting surface, with the garment surface's water-conducting ability being greater than that of the skin-contacting surface. This allows moisture on the skin-contacting surface to be transferred toward the garment surface, achieving a one-way moisture conduction characteristic from the base to the fabric surface.

[0022] Using a specific cross-needle structure, the fabric's main body weight is ≤75GSM, ensuring that the fabric is light and thin, improving breathability, making it more comfortable to wear and enhancing the wearing experience. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, removable connections, or integral connections. They may refer to mechanical connections or electrical connections. They may refer to direct connections or indirect connections through an intermediary, and they may refer to internal communication between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0029] A lightweight, breathable, quick-drying, differentiated moisture-conducting warp-knitted fabric comprises a fabric body, the fabric body being woven from at least two or more yarns, including yarn Y1 and yarn Y2. The fabric body comprises a clothing surface and a skin-contacting surface, the skin-contacting surface being an extension line layer, and the clothing surface being a coil and column layer. Yarn Y1 is woven to form the skin-contacting surface of the fabric body, and yarn Y2 is woven to form the clothing surface of the fabric body. The fineness of yarn Y1 is less than 40D, and the fineness of yarn Y2 is less than 60D. The ratio of the diameter D1 of yarn Y1 to the diameter D2 of yarn Y2 is ≤0.7, and the water-conducting capacity LpY2 of yarn Y2 and yarn Y1 is: LpY1≥1.8. The extension line of yarn Y1 spans 2 to 8 stitches, which is 1 to 4 stitches more than the span of yarn Y2. The gram weight of the fabric body is ≤75 GSM. By differentiating yarns Y1 and Y2 and spanning a specific needle count, yarn usage is reduced, resulting in a lighter, thinner fabric with improved breathability. Yarn Y1 forms the skin-facing surface, so its diameter is smaller, while yarn Y2, as the garment surface, requires a larger diameter for better water conduction.

[0030] Through the above settings, the water conductivity of the clothing surface is greater than that of the skin-contacting surface. When there is moisture on the skin-contacting surface, the moisture will be quickly transferred to the clothing surface, forming differentiated moisture conductivity.

[0031] The yarn Y1 and the yarn Y2 are both non-elastic yarns. The yarn Y1 and the yarn Y2 are non-elastic yarns made of the same material or different materials, and can be filaments or staple fibers, preferably polyester fibers.

[0032] The extension line of the yarn Y1 has a span of 2 or 3 more stitches than that of the yarn Y2, which is a preferred number of knitting stitches, and can form a light and thin fabric while ensuring the tightness of the fabric.

[0033] The fabric body can be either porous or non-porous. The fabric body can be either open or closed. The provision of holes can further enhance breathability.

[0034] The skin-contacting surface and the clothing surface are respectively of warp-bend, warp-pile, warp-plain or variable structure woven in the same direction or in the opposite direction, and the skin-contacting surface and the clothing surface are of the same structure or different structures.

[0035] An elastic connecting layer is provided in the fabric body, and the elastic connecting layer connects the clothing surface and the skin-contacting surface respectively, thereby improving the overall elasticity of the fabric.
