Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fiber fabric, specifically to a kind of moisture absorption and ventilation antibacterial superfine fiber textile fabric. BACKGROUND

[0002] In the field of textile fabric today, the existing traditional textile fabric has obvious shortcomings in many aspects, and it is difficult to meet the diversified needs of the market.

[0003] In terms of moisture absorption and ventilation, most traditional fabrics are slow to dry after absorbing moisture when facing the sweat and moisture produced by the human body, which can cause a stuffy and sticky feeling, especially in sports or high-temperature environments, and this discomfort will be more obvious. Moreover, the ventilation performance of these traditional fabrics is generally poor, and the circulation of air inside the fabric is not smooth, making it difficult for the heat and moisture around the human body to dissipate, further reducing the comfort of wearing.

[0004] Because the human skin surface will secrete oil, sweat and other substances, the traditional fabric will become a breeding ground for bacteria and microorganisms after contacting the human body, not only producing a foul odor, but also potentially posing a threat to human health, such as causing skin allergies, itching and other problems. The existing antibacterial fabric is often treated with chemical antibacterial agents, but these antibacterial agents may gradually lose effectiveness with an increase in washing frequency, and some chemical antibacterial agents may irritate the human skin, posing a certain safety hazard. SUMMARY

[0005] The utility model aims to solve the problem of slow drying after absorbing moisture, easy to cause a stuffy and sticky feeling, poor ventilation, and difficulty in dissipating heat and moisture in traditional fabrics. In terms of antibacterial properties, the utility model provides a moisture absorption and ventilation antibacterial superfine fiber textile fabric to address the problem of bacterial growth and odor production, which threatens health.

[0006] The utility model adopts the following technical solutions to achieve the above-mentioned purpose:

[0007] A kind of moisture absorption and ventilation antibacterial superfine fiber textile fabric, including composite fiber, the rear side of the composite fiber is provided with profiled fiber inner layer, the front side of the composite fiber is provided with wet outer layer, the profiled fiber inner layer is away from the inner side of the composite fiber and is provided with hydrophilic layer, the wet outer layer is away from the outer layer of the composite fiber and is provided with hydrophobic layer, the sidewall of the composite fiber is provided with antibacterial microcapsule, the composite fiber includes straight fiber and cross fiber, the straight fiber and the cross fiber form a cross shape in the transverse direction, the profiled fiber inner layer includes superfine fiber and honeycomb mesh, the honeycomb mesh is provided in the sidewall of the superfine fiber.

[0008] Furthermore, the linear fibers are made of polyester fibers, which have high strength and abrasion resistance, ensuring the structural stability of the composite fibers.

[0009] Furthermore, the cross-fiber is a polyacrylonitrile fiber containing silver nanoparticles. The silver nanoparticles are uniformly distributed inside the cross-fiber, which enhances the antibacterial properties of the composite fiber and can effectively destroy the cell membrane and DNA structure of microorganisms such as bacteria and fungi, thereby achieving a long-lasting antibacterial effect.

[0010] Furthermore, the honeycomb mesh is evenly distributed in a near-circular shape on the sidewalls of the microfiber, which effectively promotes air circulation, improves the breathability of the inner layer of the irregular fiber, provides more channels for the diffusion of moisture inside the fiber, and further optimizes the moisture absorption and breathability of the fabric.

[0011] Furthermore, the hydrophilic layer is made of hydrophilic polyurethane material and is uniformly coated on the inner side of the irregular fiber inner layer through a chemical coating process to form a firm and uniform hydrophilic layer that can quickly capture and absorb moisture from the surface of human skin.

[0012] Furthermore, the moisture-wicking outer layer is woven from modified polyamide fibers, and the fiber surface is treated with a microgroove structure, which facilitates the rapid conduction of moisture to the outside. The moisture conducted from the hydrophilic layer can be quickly conducted to the outside of the fabric under the guidance of the microgrooves, which greatly improves the overall moisture-wicking efficiency of the fabric.

[0013] Furthermore, the hydrophobic layer is a fluoropolymer coating, which is attached to the outer side of the moisture-wicking outer layer by physical vapor deposition technology. Due to the strong electronegativity and low surface energy of fluorine atoms in its molecules, the fluoropolymer gives the coating excellent hydrophobic properties.

[0014] Furthermore, the outer shell of the antibacterial microcapsule is made of biodegradable polylactic acid material, and the inside is encapsulated with plant extract antibacterial agent. When subjected to friction or temperature changes, the antibacterial agent is slowly released to exert an antibacterial effect and effectively inhibit the growth and reproduction of bacteria, fungi and other microorganisms on the fabric surface.

[0015] Furthermore, the composite fiber, the inner layer of the irregular fiber, the outer layer of the moisture-wicking layer, the hydrophilic layer and the hydrophobic layer are tightly bonded together through a hot-pressing composite process.

[0016] Compared with the prior art, this utility model provides a moisture-wicking, breathable, and antibacterial microfiber textile fabric, which has the following beneficial effects:

[0017] This moisture-wicking, breathable, and antibacterial microfiber textile fabric is made of composite fibers composed of straight and cross-shaped fibers in a cross shape, providing structural support for the fabric. It has an inner layer of irregularly shaped fibers and a moisture-wicking outer layer on the front and back, respectively. The inner layer contains microfibers with a large specific surface area and honeycomb mesh to facilitate breathability, while the outer layer is treated with microgrooves for efficient moisture wicking. In addition, the fabric absorbs moisture through the hydrophilic layer on the inside and is waterproof through the hydrophobic layer on the outside. There are also antibacterial microcapsules interspersed on the sidewalls of the composite fibers. All layers work together to achieve multiple functions such as moisture absorption, breathability, and antibacterial properties. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] like Figures 1-6As shown, a moisture-wicking, breathable, and antibacterial microfiber textile fabric includes a composite fiber 1, a profiled fiber inner layer 2 on the back side of the composite fiber 1, a moisture-wicking outer layer 3 on the front side of the composite fiber 1, a hydrophilic layer 4 on the inner side of the profiled fiber inner layer 2 away from the composite fiber 1, a hydrophobic layer 5 on the outer side of the moisture-wicking outer layer 3 away from the composite fiber 1, and antibacterial microcapsules 6 interlaced in the sidewalls of the composite fiber 1. The composite fiber 1, the profiled fiber inner layer 2, the moisture-wicking outer layer 3, the hydrophilic layer 4, and the hydrophobic layer 5 are tightly bonded together by a hot-pressing composite process.

[0028] Among them, the hydrophilic layer 4 is made of hydrophilic polyurethane material and is uniformly coated on the inner side of the irregular fiber inner layer 2 through a chemical coating process to form a firm and uniform hydrophilic layer, which can quickly capture and absorb moisture from the surface of human skin, laying the foundation for the subsequent moisture-wicking process.

[0029] Among them, the moisture-wicking outer layer 3 is woven from modified polyamide fibers. The fiber surface is treated with a microgroove structure, which facilitates the rapid conduction of moisture to the outside. The moisture conducted from the hydrophilic layer 4 can be quickly conducted to the outside of the fabric under the guidance of the microgrooves, which greatly improves the overall moisture-wicking efficiency of the fabric and effectively prevents moisture from accumulating inside the fabric.

[0030] Among them, the hydrophobic layer 5 is a fluoropolymer coating, which is attached to the outside of the moisture-wicking outer layer 3 by physical vapor deposition technology. Due to the strong electronegativity and low surface energy of fluorine atoms in its molecules, the fluoropolymer gives the coating excellent hydrophobic properties. This hydrophobic layer can effectively prevent external moisture from penetrating into the fabric, while not affecting the outward dissipation of moisture from the fabric, thus achieving a good balance between waterproof and breathable.

[0031] Among them, the outer shell of the antibacterial microcapsule 6 is made of biodegradable polylactic acid material, and the inside is encapsulated with plant extract antibacterial agent. When subjected to friction or temperature changes, the antibacterial agent is slowly released to exert an antibacterial effect and effectively inhibit the growth and reproduction of bacteria, fungi and other microorganisms on the fabric surface.

[0033] Among them, the straight fiber 11 is made of polyester fiber, which has high strength and wear resistance, ensuring that the composite fiber 1 can maintain a stable structural shape when subjected to external forces such as tension and friction.

[0034] Among them, the cross fiber 12 is a polyacrylonitrile fiber containing silver nanoparticles. The silver nanoparticles are evenly distributed inside the cross fiber 12, which enhances the antibacterial properties of the composite fiber 1. It can effectively destroy the cell membrane and DNA structure of microorganisms such as bacteria and fungi, thereby achieving a long-lasting antibacterial effect. It works synergistically with the antibacterial microcapsule 6 to comprehensively improve the antibacterial properties of the fabric.

[0035] like Figure 5 As shown, the irregular fiber inner layer 2 includes microfiber 21 and honeycomb mesh 22. The honeycomb mesh 22 is disposed in the side wall of the microfiber 21. The honeycomb mesh 22 is evenly distributed in a near-circular shape on the side wall of the microfiber 21, which effectively promotes air circulation and improves the breathability of the irregular fiber inner layer 2. At the same time, it provides more channels for the diffusion of moisture inside the fiber, further optimizing the moisture absorption and breathability of the fabric.
