Description

Technical Field

[0001] This utility model relates to the field of multifunctional textile fabric technology, specifically to an underwear fabric with moisture-absorbing, skin-protecting, warmth-keeping, and odor-eliminating functions. Background Technology

[0002] The current problem of limited functionality in underwear fabrics is prominent, making it difficult to meet consumers' comprehensive needs for comfort, health, and multifunctionality.

[0003] Traditional fabrics like pure cotton, while skin-friendly, dry slowly after absorbing moisture, easily leading to bacterial growth and odor residue. Chemical fiber fabrics are prone to static electricity and have poor breathability. Some existing technologies achieve functional enhancement through multi-layer composites or the addition of chemical finishing agents, but these suffer from weak interlayer bonding, insufficient functional durability, and skin irritation from chemical residues. For example, some multi-layered fabrics rely on simple bonding or sewing processes, affecting elasticity and comfort; while solutions that add antibacterial functions through finishing have poor wash resistance, with significant functional degradation after multiple washes.

[0004] In the prior art, the multi-layer fabric structure disclosed in publication number CN210501699U achieves functional zoning by setting multiple layers such as a skin-friendly layer, a moisture-absorbing layer, and a thermal insulation layer. However, the layers are mostly connected by stitching, which makes them prone to delamination and lacks elasticity. In addition, the selection of functional materials lacks systematic coordination. For example, the properties of the moisture-absorbing layer and the thermal insulation layer conflict, resulting in obstructed moisture expulsion and a stuffy feeling. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide an underwear fabric with moisture-absorbing, skin-protecting, warmth-keeping and odor-removing functions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An underwear fabric with moisture-wicking, skin-protecting, warmth-retaining, and odor-eliminating functions includes:

[0008] It includes a three-layer structure that is stacked from the inside out and fixedly connected by environmentally friendly hot melt adhesive technology: a skin-friendly layer, a functional core layer, and a thermal insulation and protective layer;

[0009] The skin-friendly layer is a blend of natural colored cotton fibers and modal fibers, which is formed by weft knitting to create a uniformly distributed breathable pore structure.

[0010] The functional core layer is an antibacterial and temperature-regulating layer made of hemp fiber, chitin fiber and merino wool composite.

[0011] The thermal insulation and protective layer is a bird's-eye fabric structure formed by interweaving Lycra and Tencel fibers.

[0012] Furthermore, the breathable pore size of the skin-friendly layer is 0.2–0.3 mm, and the density is 200–300 pores / m².

[0013] Furthermore, in the skin-friendly layer, the mass ratio of natural colored cotton fibers to modal fibers is 55-65:35-45.

[0014] Furthermore, in the functional core layer, the mass ratio of hemp fiber, chitin fiber and merino wool is 45–55:25–35:15–25.

[0015] Furthermore, in the bird's-eye fabric structure of the thermal insulation protective layer, the pore size of the bird's-eye holes is 0.1–0.3 mm, and the distribution density is 150–200 holes / square centimeter.

[0016] Furthermore, the environmentally friendly hot melt adhesive technology uses a polyamide-based hot melt adhesive film with a melting point of 110–120℃; the composite processing temperature is 120–140℃, and the pressure is 0.3–0.5MPa.

[0017] Furthermore, the fabric is also treated by soaking in a green tea extract solution with a concentration of 5–8%.

[0018] Furthermore, the weaving density of the functional core layer 2 is 35–40 stitches per inch.

[0019] Furthermore, the total thickness of the fabric is 0.8–1.2 mm, and the total areal density is 140–160 g / m².

[0020] The advantages of this invention compared to existing technologies are as follows:

[0021] 1. The skin-contact layer utilizes a blend of natural colored cotton and modal fabric with a breathable porous structure to achieve moisture absorption and wicking; the functional core layer, composed of hemp, chitosan, and merino wool, provides antibacterial, deodorizing, and dynamic temperature regulation; the thermal insulation and protective layer employs a bird's-eye fabric structure and a hydrophobic coating to achieve warmth and windproofing. Each layer has a clearly defined function and is bonded together with thermal fusion to form a stable whole.

[0022] 2. The vent holes and bird's eye holes form a gradient ventilation mechanism to avoid moisture accumulation between layers; the hot melt bonding technology replaces traditional suturing, improving the interlayer bonding strength and elastic recovery.

[0023] 3. Natural fibers are used instead of chemical finishing agents to improve safety and washability; refined material parameters ensure continuous functionality. Attached Figure Description

[0028] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0029] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figures 1 to 2 As shown, this embodiment provides an underwear fabric with moisture-absorbing, skin-protecting, warmth-retaining, and odor-eliminating functions, comprising a three-layer structure arranged sequentially from the inside out and fixedly connected by environmentally friendly hot-melt bonding technology: a skin-friendly layer 1, a functional core layer 2, and a heat-insulating and protective layer 3.

[0031] The skin-friendly layer 1 is made of natural colored cotton fiber (undyed, fineness 1.5dtex) and modal fiber (dry breaking strength ≥3.2cN / dtex) in a mass ratio of 60:40; the functional core layer (2) is made of hemp fiber, chitin fiber and merino wool in a mass ratio of 50:30:20; the thermal insulation and protective layer (3) is made of Lycra fiber and Tencel fiber in a yarn ratio of 70:30. The adhesive used is polyamide hot melt adhesive film with a melting point of 115℃.

[0032] The skin-friendly layer (1) is formed by weft knitting to create breathable pores with a diameter of 0.25 mm and a density of 250 pores / square meter; the functional core layer (2) is woven using warp knitting technology with a density of 38 needles / inch; the thermal insulation and protective layer (3) is woven by bird's-eye loom with a bird's-eye hole diameter of 0.2 mm and a density of 180 pores / square centimeter.

[0033] The three layers of material are stacked in sequence, with a hot melt adhesive film laid in the middle, and then hot-pressed in a laminator at 130°C and 0.4MPa for 60 seconds.

[0034] The composite fabric was immersed in 6.5% green tea extract at 50°C for 25 minutes, and then dehydrated, dried and shaped.

[0035] The fabric has a total thickness of 1.0mm, a surface density of 150g / m², and an interlayer peel strength of ≥8N / 5cm.

[0036] In this embodiment, the proportions of the functional core layer materials are optimized: the proportion of hemp fiber is increased to 55%, chitin fiber is adjusted to 25%, and merino wool is 20%, in order to improve moisture absorption and antibacterial properties. The thickness of the hydrophobic coating on the surface of the thermal insulation protective layer (3) is controlled to 0.01 mm to further enhance wind resistance. The remaining processes are the same as in Embodiment 1.

[0037] During fabric operation: The skin-friendly layer (1) quickly absorbs moisture from the skin surface through its breathable pore structure and hydrophilic fibers; the moisture is guided to the outside through the hemp and chitosan fibers in the functional core layer (2), where the high hygroscopicity of the hemp fibers and the antibacterial properties of the chitosan work together to inhibit odor growth; Merino wool forms a thermal barrier layer to reduce heat loss. The bird's-eye structure of the thermal insulation layer (3) locks in air for insulation, while the hydrophobic coating prevents external moisture from intruding. Hot-melt bonding ensures the consistency of the three layers' deformation and avoids separation between layers during activity.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
