Description

Technical Field

[0001] This invention relates to the field of clothing fabrics, specifically to a biomimetic breathable fabric and its manufacturing process. Background Technology

[0002] Bionics is the simulation of nature. Applying bionic principles to fabric design and development is an innovation in fabric research and development, especially in the filament manufacturing industry. Furthermore, it allows for the addition of other elements, resulting in fabrics that meet consumer needs and possess new functions.

[0003] Among existing fabrics, those with relatively low breathability tend to cling to the body, resulting in poor wearing comfort. Alternatively, fabrics designed to be thin or have perforations to increase breathability are prone to issues like see-through problems or low structural strength, leading to easy tearing. Furthermore, thin garments, prioritizing breathability, often have simpler structural or aesthetic designs, which can diminish their overall aesthetic appeal. Summary of the Invention

[0004] The purpose of this invention is to provide a biomimetic breathable fabric and a manufacturing process for the biomimetic breathable fabric, aiming to improve the problem that existing fabric designs have limited functionality, which can easily lead to clothing with low aesthetic appeal or low comfort in terms of structural design.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a biomimetic breathable fabric, comprising:

[0006] A composite surface layer comprising, sequentially bonded from the outside in, a biomimetic surface layer, a waterproof and breathable membrane, and a tulle underlayer, wherein the biomimetic surface layer is formed by a four-way elastic woven fabric; and

[0007] The inner layer is woven from antibacterial yarn and is placed on the bottom layer of the floating yarn.

[0008] The pores of the inner fabric layer are larger than the mesh of the bottom layer of the voile fabric, and the pores of the biomimetic outer fabric layer are larger than the mesh of the bottom layer of the voile fabric.

[0009] Preferably, multiple adhesive points are arranged in a matrix between the waterproof and breathable membrane and the biomimetic surface layer, and between the waterproof and breathable membrane and the tulle bottom layer.

[0010] Preferably, the biomimetic surface layer is molded with a scale-like texture or a feather-like texture, or the biomimetic surface layer is molded with a faux leather texture.

[0011] Preferably, the inner layer is woven from milk threads.

[0012] Preferably, the four-sided elastic structure is a woven unit with the smallest pattern;

[0013] The first weft yarn of the four-sided elastic structure interweaves with the first, third, fifth, and seventh warp yarns to form weaving points;

[0014] The second weft yarn of the four-sided elastic structure interweaves with the second, fourth, sixth, and eighth warp yarns to form weaving points;

[0015] The third weft yarn of the four-sided elastic structure interweaves with the first, third, and seventh warp yarns to form a weave point;

[0016] The fourth weft yarn of the four-sided elastic structure interweaves with the second, fourth, sixth, and eighth warp yarns to form weaving points;

[0017] The fifth weft yarn of the four-sided elastic structure interweaves with the first and fifth warp yarns to form a weave point;

[0018] The 6th weft yarn of the four-sided elastic structure interweaves with the 2nd, 4th, 6th and 8th warp yarns to form a weave point;

[0019] The 7th weft yarn of the four-sided elastic structure interweaves with the 1st, 3rd, and 7th warp yarns to form a weave point;

[0020] The 8th weft yarn of the four-sided elastic structure interweaves with the 2nd, 4th, 6th and 8th warp yarns to form a weave point.

[0021] Preferably, the weft and warp yarns of the four-way elastic structure are core-spun yarns of 30D nylon and 20D spandex.

[0022] Preferably, the warp and weft yarns of the bottom layer of the voile fabric are polyester fibers.

[0023] Preferably, the fabric density of the biomimetic surface layer is 228*117g / m³ to 245*132g / m³.

[0024] A manufacturing process for a biomimetic breathable fabric is also provided, including the following steps:

[0025] To produce biomimetic breathable fabrics as described above;

[0026] The biomimetic breathable fabric is pretreated by removing sizing and impurities, followed by singeing.

[0027] The pre-treated biomimetic breathable fabric is pre-shaped.

[0028] The pre-designed biomimetic breathable fabric was dyed. The dyeing auxiliary formula used in the dyeing process was: 1-2 g / L ammonium sulfate, 2-3 g / L acidic leveling agent, 1-3 g / L chelating dispersant, 0.01%-0.04% weakly acidic pale yellow and 0.1-0.3% acidic turquoise blue, mixed at a liquor ratio of 1:20 and dyed at 120℃ for 40 minutes.

[0029] After the biomimetic breathable fabric has been dyed, it is washed with cold water and then subjected to a color-fixing treatment. The auxiliary agent formula for the color-fixing process is: 2% to 3% acidic color-fixing agent and 1.5 g / L glacial acetic acid, with a liquor ratio of 1:25, to adjust the pH value of the color-fixing solution to 4.0 to 5.0.

[0030] After the bionic breathable fabric with color fixation is washed, it is taken out and dried at 130℃~145℃.

[0031] After drying, the biomimetic breathable fabric is molded to create a biomimetic texture, resulting in a biomimetic breathable fabric with a biomimetic texture.

[0032] Preferably, the washing process for the biomimetic breathable fabric after color fixing is as follows:

[0035] Add soap powder of 1.0-2.3 g / L to water at a bath ratio of 1:10, wash at room temperature for 30 minutes, and then drain.

[0036] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0037] The entire biomimetic breathable fabric consists of two layers: a relatively thick composite outer layer and a skin-friendly and antibacterial inner layer, providing excellent skin-friendliness. Simultaneously, by adjusting the size of the pores and mesh, the breathability of the biomimetic breathable fabric is ensured. This achieves the goal of enhancing aesthetics and innovation through the biomimetic outer layer while maintaining breathability and skin-friendliness, thus improving practicality.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] Additionally, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" are all based on the orientation or positional relationship shown in the accompanying drawings. They are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element of the present invention must have a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0049] When an element is referred to as being "fixed to," "set on," or "contained on" another element, it can be directly on or indirectly on that other element. When an element is referred to as being "connected to," it can be directly connected to or indirectly connected to that other element.

[0050] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] Example 1

[0052] Please refer to Figure 1As shown, this embodiment provides a biomimetic breathable fabric, including a composite surface layer 10 and an inner layer 20. The composite surface layer 10 includes a biomimetic surface layer 101, a waterproof and breathable membrane 102, and a wavy bottom layer 103, which are sequentially bonded from the outside to the inside. The biomimetic surface layer 101 is woven into a four-way elastic structure 1011. The inner layer 20 is woven into an antibacterial yarn and is disposed on the wavy bottom layer 103. The fabric pores of the inner layer 20 are larger than the fabric mesh of the wavy bottom layer 103, and the fabric pores of the biomimetic surface layer 101 are larger than the fabric mesh of the wavy bottom layer 103.

[0053] Specifically, antibacterial yarn can be milk silk yarn. The main raw material of milk silk yarn or fiber is milk protein, thus it contains seventeen kinds of nutritious amino acids. It also has natural and long-lasting antibacterial properties, achieving a broad-spectrum antibacterial rate of over 80% against Staphylococcus aureus, Candida albicans, fungi, and molds. Due to the active proteins in the fiber, it has a moisturizing effect on the skin. Home textile fabrics blended with other fibers are fine, lightweight, breathable, smooth, and have an elegant and luxurious luster and vibrant colors.

[0054] The milk-filled quilt is soft and gentle, with good heat retention and elasticity. It promotes sleep, is mite-proof and antibacterial, and is beneficial to health, making it especially suitable for people with allergies. Therefore, the biomimetic breathable fabric possesses excellent skin-friendly and antibacterial properties.

[0055] Furthermore, the composite surface layer 10 adopts a three-layer structure, and the waterproof and breathable membrane 102 is a new type of polymer waterproof material. The waterproof and breathable membrane 102 mainly consists of three layers: PP spunbond nonwoven fabric, PE polymer breathable membrane, and PP spunbond nonwoven fabric. The spunbond nonwoven fabric primarily enhances tensile strength and hydrostatic pressure, and protects the intermediate layer (breathable membrane). True breathability mainly relies on the intermediate PE polymer breathable membrane. In the state of water vapor, water particles are very small. According to the principle of capillary motion, they can easily permeate to the other side of the capillary, thus causing vapor permeation. When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the mutual "pulling and resistance" between water molecules), water molecules cannot easily detach from the water droplets and permeate to the other side, thus preventing water penetration and giving the breathable membrane its waterproof function.

[0056] Therefore, when the waterproof and breathable membrane 102 is bonded between the biomimetic surface layer 101 and the tulle bottom layer 103, the composite surface layer 10 has good waterproof and breathable properties. At the same time, the tulle bottom layer can cover the waterproof and breathable membrane 102, improving the structural strength of the composite surface layer 10 without causing an excessive increase in the weight of the composite surface layer 10. Therefore, the lightweight and thin characteristics of the tulle make it a good supporting material.

[0057] Furthermore, the bottom layer 103 of the voile fabric is woven from polyester fiber material, also known as polyester fiber or polyester cellulose fiber, commonly referred to as "polyester". Polyester fiber has the advantages of excellent wrinkle resistance and shape retention, as well as high strength and elastic recovery; the fabric woven from it is strong and durable, wrinkle-resistant, requires no ironing, and does not attract lint. It can be well bonded or sewn with the inner layer 20, improving the practicality of the biomimetic breathable fabric.

[0058] Specifically, in this embodiment, multiple adhesive points are arranged in a matrix between the waterproof and breathable membrane 102 and the biomimetic surface layer 101, and between the waterproof and breathable membrane 102 and the tulle bottom layer 103. Through the matrix adhesive point design, the adhesion can be guaranteed, while the breathability of the waterproof and breathable membrane 102 will not be affected, thus improving practicality.

[0059] In this embodiment, the biomimetic surface layer 101 is molded with scale-like or feather-like textures, or it is molded with simulated leather textures, i.e., the skin color and texture of animals. By printing different biological textures, different biological or plant textures are formed on the biomimetic breathable fabric to enhance the biomimetic aesthetics of the fabric.

[0060] like Figure 2 As shown, in this embodiment, the four-way elastic structure 1011 is the smallest pattern woven knitting unit; the first weft yarn of the four-way elastic structure 1011 interweaves with the first, third, fifth, and seventh warp yarns to form a weaving point; the second weft yarn of the four-way elastic structure 1011 interweaves with the second, fourth, sixth, and eighth warp yarns to form a weaving point; the third weft yarn of the four-way elastic structure 1011 interweaves with the first, third, and seventh warp yarns to form a weaving point; the fourth weft yarn of the four-way elastic structure 1011 interweaves with the second and fourth warp yarns... The 6th and 8th warp yarns interweave to form a weave point; the 5th weft yarn of the four-way stretch structure 1011 interweaves with the 1st and 5th warp yarns to form a weave point; the 6th weft yarn of the four-way stretch structure 1011 interweaves with the 2nd, 4th, 6th, and 8th warp yarns to form a weave point; the 7th weft yarn of the four-way stretch structure 1011 interweaves with the 1st, 3rd, and 7th warp yarns to form a weave point; the 8th weft yarn of the four-way stretch structure 1011 interweaves with the 2nd, 4th, 6th, and 8th warp yarns to form a weave point.

[0061] Specifically, the four-way stretch structure 1011 is a minimum pattern structure of 8 yarns by 8 yarns. The four-way stretch structure 1011 includes an outer enclosure structure, which is the enclosure structure formed by the 1st, 2nd, and 8th weft yarns and the 1st, 2nd, and 8th warp yarns. The enclosed interior is in the shape of an "X", which can create a breathable effect in the middle, that is, form a breathable hole, thus ensuring that the composite surface layer 10 has good breathability.

[0062] Furthermore, in this embodiment, the weft and warp yarns of the four-way stretch structure 1011 are core-spun yarns of 30D nylon and 20D spandex, leveraging the advantages of nylon filaments—stiffness, wrinkle resistance, easy washing, and quick drying—while also utilizing the elasticity of the outer spandex fiber. Therefore, the biomimetic surface layer 101 has a quick-drying effect, and combined with the performance of the waterproof and breathable membrane 102, it possesses excellent waterproof and breathable properties.

[0063] In this embodiment, the fabric density of the biomimetic surface layer 101 is 228*117g / m² to 245*132g / m². Fabric density refers to the warp and weft density of the fabric, that is, the number of warp and weft yarns per square inch of fabric. Preferably, the biomimetic surface layer 101 fabric can have a density of 233*124g / m², a weight of 85g, and a width of 130cm. By setting a relatively high density, the structural strength of the fabric can be ensured, while also better reflecting the printed biomimetic texture.

[0064] Example 2

[0065] This embodiment provides an outer garment made from the biomimetic breathable fabric described in Embodiment 1. The outer garment 1, for example, can be a jacket, made by cutting and sewing the biomimetic breathable fabric. The biomimetic patterns on the outer garment 1 enhance its aesthetic appeal; simultaneously, the design of excellent breathability and waterproofing improves the various properties of the outer garment 1 (giving it multiple functions) and provides excellent wearing comfort. Furthermore, the inner layer of the outer garment 1 is made of milk silk, giving it excellent antibacterial and skin-friendly properties, greatly enhancing its functionality.

[0066] Example 3

[0067] like Figure 4 As shown, this embodiment provides a manufacturing process for a biomimetic breathable fabric, including the following steps:

[0068] S101. Produce the biomimetic breathable fabric as described in Example 1.

[0069] Specifically, the finished biomimetic breathable fabric needs to be inspected. The inspection includes checking the fabric's width, warp and weft density and strength, appearance defects, oil stains or damage, etc., to ensure that the biomimetic breathable fabric meets the quality standards before entering the subsequent dyeing and finishing process, so as to avoid waste.

[0070] S102. Remove the sizing agent and impurities from the biomimetic breathable fabric, and then perform a singeing pretreatment.

[0071] Specifically, after the yarn is spun, loose, finite ends protrude from the yarn surface, forming fluff of varying lengths. Therefore, singeing removes this fluff from the fabric surface, resulting in a smooth finish.

[0072] S103. The pre-treated biomimetic breathable fabric is pre-shaped.

[0073] Pre-setting, also known as heat setting, refers to the process of obtaining the desired shape of a fabric and maintaining its stability through heat setting treatment. Specifically, utilizing the thermoplasticity of fibers, the fabric is heated to the required temperature (140-150℃) under a certain tension (10% overfeed) and held at that temperature for a period of time (3-5 minutes), and then rapidly cooled to stabilize the fabric's dimensions and shape. This process is called pre-setting or heat setting.

[0074] Fabrics that have undergone heat setting have the following advantages: 1. They can eliminate internal stress and improve the dimensional stability of the fabric; 2. They can eliminate wrinkles on the fabric; 3. They can improve the strength, hand feel, and surface smoothness of the fabric; 4. They can improve the dyeing performance of plant materials and reduce pilling.

[0075] S104. The pre-designed biomimetic breathable fabric is dyed. The dyeing auxiliary agent formula used in the dyeing process is as follows: 1-2 g / L ammonium sulfate, 2-3 g / L acidic leveling agent, 0.5-1.5 g / L chelating dispersant, 0.01%-0.04% weakly acidic pale yellow and 0.1-0.3% acidic turquoise blue, mixed at a liquor ratio of 1:20, and dyed at 110℃ for 40 minutes.

[0076] Specifically, dyeing is required to achieve the desired color in fabric. The dyeing process using weakly acidic dyes involves the presence of amino and carboxyl groups in nylon fibers. When glacial acetic acid is added, the amino groups combine with hydrogen ions, giving the fiber a positive charge, which attracts the negatively charged dye ions. Simultaneously, van der Waals forces and hydrogen bonds also exist between the fiber and the dye. When the dye bath is weakly acidic, van der Waals forces and hydrogen bonds play a dominant role. This results in the acidic dyeing effect.

[0077] S105. After the biomimetic breathable fabric has been dyed, it is washed with cold water and then subjected to a color-fixing treatment. The auxiliary agent formula for the color-fixing process is: 2% to 3% acidic color-fixing agent and 1.5 g / L glacial acetic acid, with a liquor ratio of 1:25, to adjust the pH value of the color-fixing solution to 4.0 to 5.0.

[0078] In the above process, the addition of glacial acetic acid causes the amino groups to combine with hydrogen ions, giving the fiber a positive charge. This attracts negatively charged dye ions, which is the process of color fixation. The use of an acidic fixing agent allows the pH of the dyeing solution to be adjusted to between 4.0 and 5.0, ensuring a stable color fixation process.

[0079] S106. After washing the bionic breathable fabric that has been color-fixed, take it out and dry it at a temperature between 130℃ and 145℃.

[0080] After the color-fixing bionic breathable fabric is washed, it needs to be dried within 12 hours to allow it to dry quickly for subsequent steps.

[0081] The washing process for the biomimetic breathable fabric after color fixing is as follows: 1 g / L of detergent is added to water at a liquor ratio of 1:10, and the mixture is washed at room temperature for 30 minutes and then drained; 2.0-4.0% of dispersible color fixing agent is added to water at a liquor ratio of 1:10, and the mixture is washed at 50℃ for 30 minutes and then drained; 1.0-2.3 g / L of soaping powder is added to water at a liquor ratio of 1:10, and the mixture is washed at room temperature for 30 minutes and then drained.

[0082] S107. The dried biomimetic breathable fabric is molded with a biomimetic texture to obtain a biomimetic breathable fabric with a biomimetic texture.

[0083] Specifically, the biomimetic pattern is printed using a corresponding biomimetic mold to generate the desired biomimetic breathable fabric pattern, thereby improving the aesthetics of the fabric surface. In this embodiment, after color fixing, the biomimetic breathable fabric undergoes a pre-shrinking treatment process: the pre-shrinking solution is formulated with 2-3 g / L of degreasing agent, 0.5-1.5 g / L of chelating dispersant, and 3-4 g / L of soda ash, at a liquor ratio of 1:8, and kept at 100°C for 30 minutes. This improves the shaping effect of the biomimetic breathable fabric.

[0084] The following samples were prepared using the methods described above:

[0085]

[0086] Components and manufacturers

[0087]

[0088]

[0089] Samples 1-4 were tested for color fastness to washing according to GB / T12490-2007. The color fastness to washing was measured and all samples reached level 4 or above. It can be seen that the fabric has good color fastness to washing after the color fixing process of the present invention.

[0090] Compared with sample 4, samples 1-3 showed a significant decrease in shrinkage during the first wash and a very small shrinkage during the second wash, thus maintaining the garment's shape well.

[0091] Comparative Example

[0092] The patent application document "A dyeing and finishing process for an elastic and soft nylon fabric" (application number: 202010298817.7) describes a soaping and color-fixing process as follows: the dyed fabric is soaped for 15, 16, 17, 19 or 15 minutes, wherein the soaping solution contains 10, 12, 15, 18 or 20 g / L of D&Pclear, a non-foaming soaping agent produced by Dongfang Meijie Molecular Materials Technology Co., Ltd., and then fixed for 20, 25, 30, 36 or 40 minutes, wherein the color-fixing solution contains 30, 34, 40, 46 or 50 g / L of YD-1012 chlorine-resistant color-fixing agent produced by Yingda Textile Auxiliaries Co., Ltd.

[0093] Soap washing and color fixing processes

[0094]

[0095] Based on the above comparative examples, it can be seen that the amount of the mist cannon soap detergent and YD-1012 chlorine-resistant color-fixing agent used is relatively large, and the color-fixing time is also relatively long, so that a water washing fastness of level 5 (comparative example 5) can be achieved, but the processing cost is relatively high.

[0096] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
