Description

Technical Field

[0001] This utility model relates to the field of functional textile materials, specifically to a warp-knitted elastic fabric structure that combines warmth retention, one-way moisture wicking, and quick drying properties, suitable for outdoor sportswear and close-fitting thermal clothing. Background Technology

[0002] Current conventional thermal fabrics (such as fleece and down) primarily achieve warmth by trapping still air through a thickened structure. However, this design has significant drawbacks: the fabric is heavy and has poor moisture permeability, leading to sweat buildup and a damp, cold feeling, significantly reducing its warmth retention. For example, Chinese patent CN119858358A proposes using a double-layered fabric to form a down filling layer, with a waterproof and breathable membrane laminated on the surface to improve warmth. However, this structure still significantly weakens its insulation effect when internal moisture liquefies or when sweat accumulates in the skin-contact layer due to moisture retention. To improve moisture wicking, unidirectional moisture-wicking fabrics use wicking action to guide sweat from the skin-contact layer to the outer layer of the garment. However, this design presents a new problem: the outer layer of the garment lacks efficient moisture diffusion channels, resulting in slow sweat diffusion and insufficient evaporation. A typical example is Chinese patent CN117822187A, which uses a polyester / spandex weft-knitted fabric combined with a cotton-wool structure, processed with a napping process to form a moisture-wicking and warm fabric. Although the capillary layer enables the directional transfer of sweat, the single structure of the clothing surface limits the droplet diffusion area, and the evaporation efficiency is still difficult to meet the needs of high-activity scenarios.

[0003] In summary, existing technologies struggle to simultaneously achieve the three functions of efficient warmth retention, stable unidirectional moisture wicking, and rapid evaporation within the same fabric system. Overcoming the bottlenecks in material structure and functional integration to develop composite fabrics that combine lightweight design, sustained warmth retention, and dynamic moisture management capabilities has become a pressing technical challenge for the industry. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a warm, single-wicking, quick-drying warp-knitted elastic fabric.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A warm, single-wicking, quick-drying warp-knitted elastic fabric includes a fabric body. The fabric body comprises a porous texture layer, a binding layer, a weft layer, and a capillary layer, which are woven integrally with yarns and distributed sequentially from the garment surface to the skin-contact surface. The porous texture layer is formed by weaving yarns Y1 and Y2. Yarn Y1 forms at least two different structural regions in the warp direction, and yarn Y2 forms at least one structural region in the warp direction. The weft layer is formed by weaving non-elastic yarn Y3 with a weft-supporting structure with a comb transverse shift number ≥ 4. The binding layer is formed by weaving elastic yarn Y4 with a warp plain, warp satin, or double warp structure.

[0007] As a further improvement, the yarn Y1 is a non-elastic yarn, and the yarn Y1 is woven in the warp direction to form at least one warp flat structure or warp chain structure area and at least one warp pile structure area.

[0008] As a further improvement, the yarn Y2 is a non-elastic yarn, and the yarn Y2 is woven in the warp direction to form at least one warp pile structure region.

[0009] As a further improvement, the yarn Y2 is also woven to form at least one warp flat structure or warp chain structure area.

[0010] As a further improvement, the tufted layer is formed by a process of brushing, tufting, or abrasioning the surface of the weft layer.

[0011] As a further improvement, the yarns Y1, Y2 and Y3 are selected from one or more combinations of polyester, nylon and polypropylene.

[0012] As a further improvement, the elastic yarn Y4 is selected from one or a combination of two of spandex and polyether ester elastic fibers, and the gap ratio between the binding layer and the porous texture layer is 0-50%.

[0013] As a further improvement, in the porous texture layer, the number of loops M1 contained in the warp flat structure or warp chain structure region woven by yarn Y1 and the number of loops N1 contained in the warp pile structure region satisfy 0. <M1 / N1≤1。

[0014] As a further improvement, in the porous texture layer, the number of braided loops M2 contained in the warp flat structure or warp chain structure region woven by yarn Y2 and the number of loops N2 contained in the warp pile structure region satisfy 0≤M2 / N2≤1.

[0015] As a further improvement, the fabric is knitted on a single-needle bed warp knitting machine with a needle density of 28-50 needles / inch and a hair height of 0.2-0.8 mm in the capillary layer.

[0016] This utility model has the following beneficial technical effects:

[0017] 1. Moisture-wicking-evaporation synergy: The capillary force of the capillary layer drives sweat, the high lateral displacement of the weft layer increases the diffusion area, and the pores of the structural layer accelerate evaporation.

[0018] 2. Warmth and Lightweight Balance: The fleece layer and the weft layer form a warm layer that stores static air, and the non-loop structure significantly reduces the fabric weight.

[0019] 3. Elasticity and Functionality in One: The restraint layer provides four-way elasticity, enhancing comfort. Attached Figure Description

[0026] Example 1

[0027] like Figure 1-3As shown, a warm, single-wicking, quick-drying warp-knitted elastic fabric includes a fabric body. The fabric body comprises a porous texture layer 1, a binding layer 2, a weft layer 3, and a capillary layer 4, all woven integrally with yarns and sequentially distributed from the garment surface to the skin-contact surface. The porous texture layer 1 is formed by weaving yarns Y1 and Y2. Yarn Y1 forms at least two different structural regions in the warp direction, and yarn Y2 forms at least one structural region in the warp direction. The weft layer 3 is formed by weaving non-elastic yarn Y3 with a weft-supporting structure of ≥4 guide bar shifts. The binding layer 2 is formed by weaving elastic yarn Y4 with a plain warp, satin warp, or double warp structure. The porous texture layer 1, as the surface layer of the fabric, has several pores for breathability. The binding layer has good elasticity, binding the fabric and providing elastic properties.

[0028] The porous texture layer refers to the fabric surface layer with breathable pores formed by a combination of different structural elements, creating air storage space through structural differences. The binding layer is a tension-regulating layer formed by weaving elastic yarns. The weft layer is a supporting structure formed by horizontally laying inelastic yarns, used to maintain the stability of the fabric's shape. The capillary layer is a capillary conduction layer formed through surface treatment, specifically by mechanical brushing, napping, or abrasion processes on the surface of the weft layer, providing good skin-friendly feel and warmth, and also serving to create directional moisture-wicking channels.

[0029] The yarn Y1 is a non-elastic yarn, and yarn Y1 is woven in the warp direction to form at least one warp flat structure or warp chain structure region A1 and at least one warp pile structure region B1. The yarn Y2 is a non-elastic yarn, and yarn Y2 is woven in the warp direction to form at least one warp pile structure region B2, and may also be selectively woven to form at least one warp flat structure or warp chain structure region A2.

[0030] By using two non-elastic yarns, Y1 and Y2, to create differentiated weave structures along the warp direction, controllable breathable pores are generated to store still air while maintaining the fabric's lightweight properties. The elastic weave structure of the binding layer dynamically adjusts the opening and closing of the pores, maintaining warmth while avoiding excessive compression. The dense structure of the weft layer, formed by a multi-comb transverse process, provides a stable base for the capillary layer, ensuring uniform distribution of hair. All functional layers achieve structural synergy through integrated weaving. The porous texture layer and the capillary layer form a continuous moisture-wicking path, while the binding layer and the weft layer together maintain the fabric's shape, keeping the moisture-wicking channels unobstructed during movement.

[0031] The capillary layer 4 and the weft layer 3 together store still air to achieve the function of warmth retention, and guide sweat from the capillary layer to the weft layer in one direction; the high lateral displacement structure of the weft layer 3 increases the moisture diffusion area and works with the porous texture layer to accelerate evaporation.

[0032] Specifically, the non-elastic yarn Y1 forms a composite structure with differentiated pore distribution by alternating weaving of warp plain or warp chain structure regions A1 and warp pile structure regions B1. Warp plain or chain structure region A1 provides support and moisture-wicking channels, while warp pile structure region B1 stores still air through fluffy loops to enhance warmth. This alternating layout of the two structural regions allows the fabric to maintain its lightweight while achieving a balance between breathability and thermal insulation.

[0033] Yarn Y2 forms a continuous network of extended yarns on the fabric surface through a warp-pile structure, creating uniform microporous channels between adjacent extended yarns. When liquid is conducted upwards through the capillary layer, the pores between the extended yarns provide lateral diffusion paths, increasing the liquid contact area. The non-elastic yarn maintains structural rigidity during weaving, preventing pore deformation due to fabric stretching and ensuring the long-term unobstructed flow of moisture-wicking channels.

[0034] By using yarns Y1 and Y2 to create various different weave structures, the problem of low moisture diffusion efficiency in the outer layer of unidirectional moisture-wicking fabrics is solved. The introduction of warp-knitted or warp-stretched structures creates longitudinally penetrating moisture-wicking channels in the porous texture layer. Sweat migrates quickly to the garment surface along these channels under capillary action, preventing accumulation on the skin-contact surface. At the same time, the dense pores in the warp-knitted areas maintain an air insulation layer, ensuring that the warmth retention performance is not affected during sweat wicking.

[0035] The yarns Y1, Y2, and Y3 are selected from one or more combinations of polyester, nylon, and polypropylene.

[0036] The elastic yarn Y4 is selected from one or a combination of two of spandex and polyether ester elastic fibers, and the gap ratio between the binding layer and the porous texture layer is 0-50%.

[0037] The Y4 elastic yarn is selected from yarns with high resilience, specifically spandex or polyether ester elastic fibers in monofilament or multifilament form. This is achieved by weaving to form a binding layer structure with continuous shrinkage force. This material selection allows the binding layer to maintain the overall elasticity of the fabric while preventing structural deformation due to excessive stretching. The gap ratio refers to the percentage of the area between the binding layer and the porous texture layer that is not covered by yarn. This can be achieved by adjusting the yarn arrangement density or weave structure. When the gap ratio is controlled between 0-50%, it maintains the three-dimensional air storage space of the porous texture layer while applying moderate pressure to the weft layer through the binding layer to maintain structural stability.

[0038] Specifically, when spandex or polyether ester elastic fibers are warp-knitted to form a binding layer, their elastic modulus complements the rigidity of the porous texture layer. When the gap ratio is 0%, the binding layer completely adheres to the porous texture layer, suitable for applications requiring high thermal insulation. When the gap ratio is increased to 50%, the created airflow channels accelerate moisture removal. By adjusting the blending ratio of the two elastic materials, the resilience of the binding layer can be precisely controlled, ensuring effective constraint on the weft layer during dynamic stretching.

[0039] Example 2

[0040] like Figure 1-3 As shown, in the porous texture layer, the number of loops M1 in the warp flat structure or warp chain structure region woven by yarn Y1 and the number of loops N1 in the warp pile structure region satisfy 0. <M1 / N1≤1。

[0041] Among them, the warp plain structure refers to the weave structure formed by interlocking loops in adjacent warp rows, which can be achieved using two-needle or three-needle warp plain knitting to form a stable mesh structure. The warp chain structure refers to the chain-like structure formed by loops extending along the warp direction, which can be achieved using open or closed chain knitting to form a continuous longitudinal chain texture. The warp pile structure refers to the weave structure formed by loops spanning multiple stitch lengths between adjacent warp rows, which can be achieved using three-needle or four-needle warp pile knitting to form a three-dimensional structure with slanted patterns. The limitation of the loop ratio M1 / N1 controls the distribution density of different structural areas, creating a gradient porosity distribution in the porous texture layer.

[0042] Specifically, during the weaving process of the porous texture layer 1, the warp pile structure region B1 forms a support area through low-density loops, while the warp flat structure or warp chain structure region A1, in conjunction with the warp pile structure region, forms a loose porous area through high-density loops. When M1 / N1 is in the range of 0 to 1, the distribution density of the dense area does not exceed that of the loose area, allowing the fabric to form a continuous, interconnected multi-level porous network while maintaining structural strength. This pore distribution gradient can guide sweat to migrate directionally along the skin-contact surface to the garment surface, while reducing heat loss through convection through the pores. For example, when M1 / N1 is 0.5, every two warp pile structure loops correspond to one warp flat structure loop, forming alternating dense and loose areas.

[0043] Example 3

[0044] like Figure 1-3 As shown, in the porous texture layer, the number of weaving loops M2 contained in the warp flat structure or warp chain structure region A2 woven by yarn Y2 and the number of loops N2 contained in the warp pile structure region B2 satisfy 0≤M2 / N2≤1.

[0045] During the weaving process of the porous texture layer, yarn Y2 forms a moisture-wicking network with a gradient porosity distribution by alternating warp flat or chain braided structures and warp pile structures A2. When M2 / N2 approaches 0, the warp pile structure region B2 dominates, forming a high-porosity region to accelerate the lateral diffusion of sweat; when M2 / N2 approaches 1, the proportion of warp flat or chain braided structures increases, forming a longitudinal support framework to prevent excessive fabric deformation. By dynamically adjusting this ratio, the capillary effect can be optimized while maintaining fabric dimensional stability, allowing sweat to quickly migrate to the capillary layer along a predetermined path.

[0046] In one embodiment, yarn Y2 can be made of 75D / 72F polyester filament, with alternating four-needle warp pile and two-needle warp plain weave in the warp direction. In every 10 rows, the warp plain weave occupies 3 rows and the warp pile occupies 7 rows, resulting in an M2 / N2 ratio of 0.43. Alternatively, 50D / 48F nylon filament can be used, with alternating single-needle chain knit and four-needle warp pile in the warp direction. In every 8 rows, the chain knit occupies 2 rows and the warp pile occupies 6 rows, resulting in an M2 / N2 ratio of 0.33.

[0047] The fabric is knitted on a single-needle bed warp knitting machine with a needle density of 28-50 needles / inch and a hair height of 0.2-0.8 mm in the capillary layer.

[0048] This application can accelerate the directional transfer of sweat from the skin to the clothing surface through an optimized wicking layer structure while maintaining the lightweight characteristics of the fabric. At the same time, it can improve the moisture diffusion efficiency by expanding the evaporation area formed by high-density weaving. This effectively solves the problem of sweat retention caused by the single moisture wicking path in the prior art, and achieves a balance between continuous dryness and warmth in dynamic activity scenarios.
