Description

Technical Field

[0001] This utility model relates to the field of fabric technology, specifically to an antibacterial textile fabric. Background Technology

[0002] As people's living standards continue to improve, the requirements for the quality and functionality of textiles are becoming increasingly stringent. In daily life, textiles are widely used in clothing, home furnishings, and other fields, often coming into contact with various bacteria, fungi, and other microorganisms. Due to the material characteristics and usage environment of textiles, they can easily become breeding grounds for bacteria, not only producing odors and affecting the user experience, but also potentially causing health problems such as skin allergies. Therefore, textile fabrics with highly effective antibacterial functions have become an urgent market demand.

[0003] Currently available antibacterial textile fabrics on the market primarily achieve their antibacterial effect by adding antibacterial agents to the fabric. Common antibacterial agents include silver ions and nanomaterials. However, these fabrics often have some shortcomings. On the one hand, the antibacterial effect is not long-lasting; its antibacterial performance gradually weakens with prolonged use and increased washing frequency. On the other hand, the antibacterial properties are relatively limited, potentially only inhibiting a few specific types of bacteria and unable to cope with complex bacterial environments. Furthermore, existing antibacterial textile fabrics are also limited in functionality. For example, their waterproof and breathable properties are poor, failing to adequately meet the needs of users in different environments. In humid environments, the fabric is easily permeated by moisture, affecting its antibacterial performance and comfort; while in active or high-temperature environments, good breathability is required to keep the user dry.

[0004] Therefore, it is necessary to propose an improved technical solution to address the aforementioned problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] An antibacterial textile fabric includes a base fabric, an antibacterial layer on the upper surface of the base fabric, a skin-friendly layer on the lower surface of the base fabric, a waterproof and breathable layer on the upper surface of the antibacterial layer, and a plurality of breathable micropores arranged in a honeycomb pattern on the waterproof and breathable layer.

[0007] The antibacterial layer has hemispherical protrusions evenly distributed on its upper surface, and the interior of each hemispherical protrusion has a hollow channel that communicates with the outside.

[0008] As a further aspect of this utility model: the antibacterial layer also contains uniformly distributed antibacterial plant extract capsule structures.

[0009] As a further aspect of this utility model: the surface of the hemispherical protrusion structure is provided with nanoscale antibacterial texture.

[0010] As a further embodiment of this utility model: the height of the hemispherical protrusion structure is 0.1 mm to 0.3 mm, and the diameter of the hollow channel is 0.05 mm to 0.1 mm.

[0011] As a further aspect of this utility model: the antibacterial layer contains nano-silver particles, chitosan fibers, and mugwort fibers.

[0012] As a further aspect of this utility model: the anti-slip layer is made of a material with anti-slip properties, and the lower surface of the anti-slip layer has a wavy, irregular texture.

[0013] As a further aspect of this invention: the skin-friendly layer is made of soft natural fibers.

[0014] As a further embodiment of this utility model: the waterproof and breathable layer is made of polytetrafluoroethylene material.

[0015] As a further embodiment of this utility model: the base material is cotton or linen.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1) The synergistic effect of multiple antibacterial components in the antibacterial layer, coupled with the increased surface area due to the hemispherical protrusion structure, gives this textile fabric a strong inhibitory effect on various bacteria, fungi and other microorganisms. It can effectively reduce bacterial growth and the possibility of odor generation, providing users with a clean and healthy wearing environment. Compared with traditional antibacterial fabrics, this fabric has a more significant antibacterial effect and can maintain high-efficiency antibacterial performance for a longer period of time, reducing the risk of health problems such as skin allergies caused by bacterial growth.

[0018] 2) The hollow channel design makes it possible for the sustained release of antibacterial ingredients. As the usage time and number of washes increase, the antibacterial ingredients can be gradually released from the hollow channel to continue to exert their antibacterial effect. This design makes the antibacterial effect of the fabric more durable and extends the service life of the fabric. At the same time, the reasonable combination of multiple antibacterial ingredients also enhances the durability of the antibacterial effect. Different antibacterial ingredients have different antibacterial mechanisms and durability. By using them in combination, they can exert their antibacterial effect at different stages and under different conditions, ensuring that the fabric always maintains good antibacterial performance.

[0019] 3) The honeycomb-shaped breathable micropores of the waterproof and breathable layer can effectively block the penetration of external moisture while ensuring that internal moisture and heat can be discharged in time. In humid environments, the fabric can prevent water from entering and keep the inside dry; in sports or high-temperature environments, it can quickly wick away moisture and heat, keeping the user comfortable at all times. This excellent waterproof and breathable performance makes the fabric suitable for various environments and occasions, providing the best wearing experience for users, whether for daily wear or outdoor sports.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-2In this embodiment of the present invention, an antibacterial textile fabric includes a base fabric 1, an antibacterial layer 2 on the upper surface of the base fabric 1, a skin-friendly layer 3 on the lower surface of the base fabric 1, a waterproof and breathable layer 4 on the upper surface of the antibacterial layer 2, and a plurality of breathable micropores 5 arranged in a honeycomb pattern on the waterproof and breathable layer 4.

[0028] The antibacterial layer 2 has hemispherical protrusions 6 evenly distributed on its upper surface, and the interior of the hemispherical protrusions 6 has a hollow channel 7 that communicates with the outside.

[0029] In this utility model, the multi-layer structure design of the antibacterial textile fabric fully considers the needs of different functions. Specifically, the base fabric 1 serves as the basic support to ensure the overall strength and stability of the fabric. The antibacterial layer 2 on the upper surface is the core part for achieving the antibacterial function, which works through specific antibacterial ingredients. The skin-friendly layer 3 on the lower surface focuses on the comfort of contact with the human body, giving users a good wearing experience. The waterproof and breathable layer 4 set above the antibacterial layer 2 cleverly combines the seemingly contradictory properties of waterproof and breathable, meeting the usage needs in different environments. This multi-layer structure works together, and the functions of each layer complement each other, so that the fabric can achieve good results in terms of antibacterial, comfort, waterproof and breathable properties.

[0030] The antibacterial layer 2 contains a variety of antibacterial ingredients, including common high-efficiency antibacterial agents such as silver ions and nanomaterials, as well as natural antibacterial ingredients such as artemisia extract. This combination can leverage the advantages of different antibacterial ingredients and enhance the diversity and durability of the antibacterial effect.

[0031] The hemispherical protrusions 6, evenly distributed on the surface of the antibacterial layer 2, greatly increase the surface area of ​​the antibacterial layer 2. More surface area means more antibacterial components can come into contact with bacteria, thereby improving the antibacterial efficiency. At the same time, the hemispherical shape is also conducive to the adhesion of bacteria to the surface and the killing of bacteria by antibacterial components. The hollow channels 7 inside the hemispherical protrusions 6 are connected to the outside and have multiple functions. First, the hollow channels 7 can increase air circulation and improve the breathability of the fabric. During wear, air can circulate through the hollow channels 7 inside the fabric, taking away moisture and heat and keeping the body dry and comfortable. Second, the hollow channels 7 play a role in adsorbing and storing antibacterial components to a certain extent. During the production process, antibacterial components can be injected into the hollow channels 7, so that they are gradually released during use, prolonging the durability of the antibacterial effect.

[0032] The honeycomb-shaped arrangement of breathable micropores 5 on the waterproof and breathable layer 4 is a major highlight of this fabric. The honeycomb structure has the characteristics of high stability and good breathability. These micropores can block the entry of external moisture while allowing internal moisture and heat to escape. When encountering external moisture, the surface tension of the micropores can prevent moisture penetration, while internal moisture and heat can diffuse out through the micropores, thus achieving the function of waterproof and breathable.

[0033] In summary, the synergistic effect of multiple antibacterial components in the antibacterial layer 2, coupled with the increased surface area from the hemispherical protrusion structure 6, gives this textile fabric a powerful inhibitory effect on various bacteria, fungi, and other microorganisms. This effectively reduces bacterial growth and the possibility of odor generation, providing users with a clean and healthy wearing environment. Compared with traditional antibacterial fabrics, this fabric has a more significant antibacterial effect and can maintain highly efficient antibacterial performance for a longer period of time, reducing the risk of health problems such as skin allergies caused by bacterial growth.

[0034] The hollow channel 7 design enables the sustained release of antibacterial ingredients. As the usage time and number of washes increase, the antibacterial ingredients can be gradually released from the hollow channel 7 to continue to exert their antibacterial effect. This design makes the antibacterial effect of the fabric more durable and extends the service life of the fabric. At the same time, the reasonable combination of multiple antibacterial ingredients also enhances the durability of the antibacterial effect. Different antibacterial ingredients have different antibacterial mechanisms and durability. By using them in combination, they can exert their antibacterial effect at different stages and under different conditions, ensuring that the fabric always maintains good antibacterial performance.

[0035] The honeycomb-shaped breathable micropores 5 of the waterproof and breathable layer 4 can effectively block the penetration of external moisture while ensuring that internal moisture and heat can be discharged in time. In humid environments, the fabric can prevent water from entering and keep the inside dry; in sports or high-temperature environments, it can quickly wick away moisture and heat, keeping the user comfortable at all times. This excellent waterproof and breathable performance makes the fabric suitable for various environments and occasions, providing the best wearing experience for users, whether for daily wear or outdoor sports.

[0036] In this embodiment of the present invention, the antibacterial layer 2 contains nano-silver particles, chitosan fibers and mugwort fibers, and the antibacterial layer 2 also contains uniformly distributed antibacterial plant extract capsule structures 8.

[0037] Nano-silver particles possess powerful antibacterial capabilities, effectively killing various bacteria; chitosan fibers naturally possess antibacterial properties and are environmentally friendly; artemisia fibers provide the antibacterial effects of traditional herbs while imparting a unique scent to the fabric; the antibacterial plant extract capsule structure 8 allows for the selection of appropriate plant extracts, such as tea tree oil, to release antibacterial components under specific conditions, enhancing the durability and diversity of antibacterial properties. The capsule structure can slowly release antibacterial components under different environmental conditions, complementing other antibacterial components to ensure that the fabric maintains highly efficient antibacterial performance at different stages of use. Moreover, the presence of the capsule structure also increases the stability and durability of the antibacterial layer 2.

[0038] In this embodiment of the invention, the surface of the hemispherical protrusion structure 6 is provided with nanoscale antibacterial texture 9.

[0039] The combination of nano-level antibacterial texture 9 and hemispherical raised structure 6 increases the stability and durability of antibacterial layer 2. The presence of texture can reduce the adhesion and accumulation of bacteria on the surface and reduce the corrosive effect of bacteria on the fabric. At the same time, the nano-level size makes the texture less prone to wear and damage, and it can still maintain good antibacterial performance even after multiple washes and long-term use.

[0040] In this embodiment of the present invention, the height of the hemispherical protrusion structure 6 is 0.1 mm to 0.3 mm, and the diameter of the hollow channel 7 is 0.05 mm to 0.1 mm.

[0041] In this system, the hemispherical protrusion structure 6 has a height of 0.1 mm to 0.3 mm. This size range can effectively increase the surface area of ​​the antibacterial layer 2, allowing more antibacterial components to come into contact with bacteria and improve the antibacterial efficiency, without affecting the overall softness and wearing comfort of the fabric due to excessive height. The hollow channel 7 has a diameter of 0.05 mm to 0.1 mm. This size can ensure good air circulation, improve the breathability of the fabric, and at the same time, it can also adsorb and store antibacterial components to a certain extent, allowing them to be gradually released during use and prolonging the durability of the antibacterial effect.

[0042] In this embodiment of the invention, the anti-slip layer is made of a material with anti-slip properties, and the lower surface of the anti-slip layer has a wavy, irregular texture.

[0043] The skin-friendly layer 3 is made of soft natural fibers;

[0044] The waterproof and breathable layer 4 is made of polytetrafluoroethylene material;

[0045] The base fabric 1 is made of cotton or linen.

[0046] The base fabric 1 is made of cotton or linen because they have good moisture absorption and breathability, keeping the skin dry, and natural materials are gentler on the body. The skin-friendly layer 3 uses soft natural fibers, such as modal fibers, which provide a soft touch and reduce skin irritation. The waterproof and breathable layer 4 uses polytetrafluoroethylene (PTFE) because of its excellent waterproof and breathable properties, effectively blocking external moisture penetration while allowing internal moisture to escape. The anti-slip layer uses anti-slip materials and features a wavy, irregular texture to increase friction between the fabric and the contact surface, preventing the fabric from slipping during use.

[0047] Furthermore, the synergistic effect of the hollow channel 7 and the waterproof and breathable layer 4 is also crucial for improving breathability. The waterproof and breathable layer 4 has several breathable micropores 5 arranged in a honeycomb pattern. These micropores are mainly used to expel internal moisture and heat. The hollow channel 7 and the breathable micropores 5 cooperate with each other in the vertical direction. When the internal air rises through the hollow channel 7 to the interface between the antibacterial layer 2 and the waterproof and breathable layer 4, it can be smoothly discharged to the outside through the breathable micropores 5. At the same time, the base fabric 1 and the skin-friendly layer 3 also have a certain degree of breathability. If the base fabric 1 is made of cotton or linen, it has good breathability. The skin-friendly layer 3 is made of soft natural fibers and will not hinder the flow of air. The breathability of this multi-layer structure is superimposed, so that the hollow channel 7 can play a better role in the entire fabric's breathability system.

[0048] In summary, the manufacturing process of this antibacterial textile fabric can be as follows:

[0049] I. Preparation of Base Fabric

[0050] 1. Choose cotton or linen materials and pre-treat them to remove impurities and short fibers. This can be achieved through washing and drying to ensure the cleanliness and dryness of the material.

[0051] 2. Based on the required fabric specifications and performance requirements, the spinning and weaving processes are carried out. Traditional spinning methods, such as ring spinning and air-jet spinning, can be used to spin cotton or linen fibers into yarn. Then, the yarn is woven into the base fabric 1 using a loom. Appropriate weaves, such as plain weave, twill weave, or satin weave, can be selected to meet different strength and appearance requirements.

[0052] II. Preparation of Antibacterial Layer 2

[0053] 1. Prepare nano-silver particles, chitosan fibers, and artemisia fibers. Nano-silver particles can be prepared using chemical reduction or physical methods, ensuring the particle size is within a suitable range. Chitosan fibers and artemisia fibers can be prepared into fibers using specific spinning processes.

[0054] 2. Formulate antibacterial plant extracts into capsule structures. Microencapsulation technology can be used to encapsulate the antibacterial plant extracts within capsules made of polymer materials, controlling the uniform distribution of capsule particle size.

[0055] 3. Mix the nano-silver particles, chitosan fibers, artemisia fibers, and antibacterial plant extract capsule structure 8 evenly. Stirring or ultrasonic treatment can be used to ensure thorough mixing of all components.

[0056] 4. The mixed antibacterial material is processed into an antibacterial layer 2 using textile technology. Weaving, knitting, or nonwoven processes can be used to process the antibacterial material into an antibacterial layer 2 with a certain thickness and strength. During processing, care should be taken to control the height of the hemispherical protrusion structure 6 to be 0.1 mm-0.3 mm, and the diameter of the hollow channel 7 to be 0.05 mm-0.1 mm. This structure can be achieved using special molds or processing equipment.

[0057] For example, using 3D printing technology: 3D printing technology can construct objects by layering materials according to a pre-designed three-dimensional model. For this hemispherical protrusion structure 6 with hollow channels 7, the model can be designed in 3D printing software, and the hollow channels 7 can be constructed by controlling the movement of the nozzle and the extrusion of material during the printing process.

[0058] Alternatively, a laser-assisted processing method can be used. First, a solid hemispherical protrusion 6 is fabricated, and then a hollow channel 7 is machined inside the hemispherical protrusion 6 using laser processing technology. Laser processing can precisely control the processing depth and diameter, and by scanning and adjusting parameters multiple times, the required size of the hollow channel 7 can be achieved.

[0059] III. Preparation of Waterproof and Breathable Layer 4

[0060] 1. Polytetrafluoroethylene (PTFE) material can be selected, either in the form of a film or a coating. For films, a microporous PTFE film can be prepared using processes such as stretching. For coatings, PTFE material can be applied to the antibacterial layer 2 using methods such as spraying or impregnation.

[0061] 2. Honeycomb-shaped permeable micropores are fabricated on polytetrafluoroethylene (PTFE) material. Methods such as laser drilling and mechanical punching can be used to control the size and uniformity of the micropore distribution.

[0062] IV. Preparation of Skin-Friendly Layer 3

[0063] 1. Choose soft natural fibers, such as Modal and Tencel. Then, use spinning and weaving processes to create a skin-friendly layer from these natural fibers.

[0064] 2. The skin-friendly layer 3 can be softened, such as by soaking or spraying with a softener, to improve the softness and comfort of the skin-friendly layer 3.

[0065] V. Preparation of Anti-slip Layer

[0066] 1. Choose materials with anti-slip properties, such as rubber or silicone. These materials can be processed into sheets or coatings.

[0067] 2. An irregular, wavy texture is created on the lower surface of the anti-slip layer. This texture can be achieved through methods such as mold embossing or engraving.

[0068] VI. Fabric Assembly

[0069] 1. The antibacterial layer 2 is attached to the upper surface of the base fabric 1, and can be fixed by methods such as hot pressing or adhesive.

[0070] 2. Attach the skin-friendly layer 3 to the lower surface of the base fabric 1, using the same appropriate fixing method.

[0071] 3. Attach the waterproof and breathable layer 4 to the upper surface of the antibacterial layer 2, ensuring that the breathable micropores 5 face upwards.

[0072] 4. Finally, attach the anti-slip layer to the lower surface of the skin-friendly layer 3 to complete the assembly of the entire antibacterial textile fabric.

[0073] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
