Description

Technical Field

[0001] This application relates to the field of textile technology, and more specifically, to a multifunctional bio-functional textile based on traditional Chinese medicine and its application method. Background Technology

[0002] With the increasing popularity of the traditional Chinese medicine concept of "prevention of disease" in the field of national health management, wearable health-care functional textiles have been widely applied and developed as an important carrier for daily health intervention. These textiles combine functional materials with textile structures, using close-fitting clothing and protective gear as carriers to achieve continuous health maintenance without affecting daily work and life. They meet the daily intervention needs of modern people in their sub-health state and have broad application scenarios and market potential.

[0003] Currently, related health textiles struggle to effectively balance the precise meridian-based conditioning needs guided by Traditional Chinese Medicine (TCM) meridian theory with overall product performance in practical applications. Existing products often employ a design that uniformly loads functional materials onto all fabrics, failing to achieve targeted enrichment of functional materials at meridian points. This results in low utilization of functional materials and difficulty in matching the conditioning logic of meridian-based warming. Some products with multi-layered functional structures rely on subsequent lamination processes, which not only fail to create unobstructed functional conduction channels, affecting the synergistic effect of different functional layers, but also suffer from insufficient fabric softness and breathability, and poor interlayer structural stability. Consequently, they cannot simultaneously meet the demands for precise targeting, synergistic efficacy, and long-term comfortable wear. Summary of the Invention

[0004] To address the problem that existing health-care functional textiles struggle to simultaneously meet the needs of precise targeted conditioning based on traditional Chinese medicine meridian theory, achieve synergistic functional effects, and maintain comfort and stability when worn close to the body for extended periods, this application provides a multifunctional bio-functional textile based on traditional Chinese medicine and its usage method.

[0005] In the first aspect, this application provides a multifunctional bio-functional textile based on traditional Chinese medicine, employing the following technical solution: A multifunctional bio-textile based on traditional Chinese medicine includes a textile body woven from a bio-functional composite fabric. The bio-functional composite fabric consists of an inner skin-friendly layer, a first functional layer, a second functional layer, and an outer strengthening layer, arranged sequentially from the inside out. These four layers are interwoven to form a porous cross-linked composite structure, creating a permeable conductive channel connecting all four layers. The bio-functional composite fabric of the textile body has meridian-targeting functional zones corresponding to the surface projection of acupoints on human meridians. These meridian-targeting functional zones are arranged in a matrix of dots matching the acupoints. Within these meridian-targeting functional zones, the mass ratio of modified fibers in the first functional layer, the second functional layer, and the outer strengthening layer is 2 to 5 times that of the modified fibers in the corresponding non-functional layers of the fabric.

[0006] By adopting the above technical solution, the inner skin-friendly layer, as the layer in direct contact with human skin, undertakes the basic functions of close-fitting comfort and moisture absorption and wicking. The first functional layer, the second functional layer, and the outer solidifying layer can each carry corresponding functional components. Through layered arrangement, different functional zones are independently laid out, avoiding mutual interference between different functional materials. The integrated warp and weft interweaving adopts a multi-layered weaving structure, allowing the four layers to form a continuous interweaving connection in the same weaving process, rather than being independently layered and then bonded. The resulting porous cross-linked composite structure not only retains the independent functional attributes of each layer, but also forms a stable structure through the interweaving points. The interlayer bonding avoids the problem of delamination during use and washing; the synchronously formed porous conduction channel that runs through four layers provides a continuous and stable medium path for the inward transmission of functional effects; the meridian-targeting functional area is pre-formed based on the surface distribution of acupoints in traditional Chinese medicine meridians, and adopts a dot matrix unit arrangement that matches the acupoints to achieve the fixed-point and controllable layout of modified fibers in the corresponding acupoint areas. Through the multiple enrichment of modified fibers, the modified fibers form a concentrated arrangement in the core area corresponding to the acupoints, and the targeted layout and precise utilization of functional materials are achieved without changing the total amount of functional materials.

[0007] Preferably, within the meridian-targeting functional area, with the center of the acupoint projection on the body surface as the origin, the mass percentage of modified fibers decreases gradually along the direction of the corresponding meridian, forming a gradient woven conduction belt extending along the meridian. The gradient woven conduction belt adopts a gradient arrangement of dots matrix that matches the meridian circulation path.

[0008] By adopting the above technical solution, the modified fiber mass ratio is designed with a gradient decrease, taking the center of the acupoint projection on the body surface as the origin. This allows the distribution of modified fibers to match the circulation path of traditional Chinese medicine meridians. Combined with a gradient arrangement of dot matrix that matches the meridian circulation path, a continuous functional gradient transition is formed from the core area of ​​the acupoint to the upstream and downstream of the meridian circulation, rather than the isolated accumulation of acupoints. This aligns with the design principle of meridian-based conditioning in traditional Chinese medicine, achieving continuous coverage from the core acupoint to the meridian circulation path. At the same time, this gradient structure and dot matrix arrangement are directly integrated and formed by dynamically adjusting the modified fiber feeding ratio during the weaving process. No subsequent secondary processing is required, and there will be no sudden changes in the local feel or thickness of the fabric, ensuring the overall wearing comfort and structural uniformity of the fabric.

[0009] Preferably, the functional components in the first functional layer, the second functional layer, and the outer solid layer are all integrally fixed with the fiber-forming polymer fiber body through fiber-level blending modification combined with bonding grafting method, and the overall porosity of the biofunctional composite fabric is 35% to 65%.

[0010] By adopting the above technical solution, fiber-level blending modification combined with bonding grafting method, functional components are uniformly dispersed in the polymer melt during the melting stage of the fiber-forming polymer, while the functional components form a stable chemical bond structure with the molecular chain of the fiber-forming polymer. After spinning, stretching and setting processes, the functional components are coated and fixed inside the fiber body formed by the polymer, rather than adsorbed on the fiber surface. In the subsequent weaving, washing and wearing processes, the functional components will not dissolve or fall off due to friction and washing, ensuring the long-term stability of the product function from the source of fiber forming. The overall porosity of 35% to 65% is achieved through the coordinated control of weaving structure, warp and weft density and setting process. This range can ensure that the fabric has continuous breathable pores to meet the needs of moisture and heat discharge when worn close to the body, and will not cause the functional effect to dissipate outward due to excessive pores. A stable fit is formed between the wearing comfort and functional transmission efficiency of the fabric.

[0011] Secondly, this application provides a method for preparing multifunctional bio-textiles for traditional Chinese medicine, employing the following technical solution: A method for preparing multifunctional bio-textiles based on traditional Chinese medicine includes the following steps: S1. Preparation of functional modified fibers: First modified fibers for the first functional layer, second modified fibers for the second functional layer, and third modified fibers for the outer solid layer are prepared respectively. The corresponding functional components are mixed with fiber-forming polymer chips in proportion, and then melt-blended and bonded by a twin-screw extruder. After spinning, stretching and shaping, the corresponding modified fibers are obtained. S2, Layered Yarn Plying and Warping: For the four-layer structure of biofunctional composite fabric, weaving yarns corresponding to each layer are prepared separately. The corresponding modified fibers and skin-friendly basic fibers are plyed and twisted according to the design ratio to obtain special yarns for each layer. Then, the special yarns for each layer are warped in batches. S3. Differentiated layered weaving and warp-targeting zone formation: The multi-arm rapier loom is used for integrated layered weaving. According to the four-layer structure layout design, the inner skin-friendly layer, the first functional layer, the second functional layer, and the outer foundation layer are interwoven and woven in an integrated manner. At the same time, at the preset warp-targeting functional zone position, the feed ratio of modified fibers is dynamically adjusted to complete the differentiated weaving of the dot matrix warp-targeting functional zone. S4. Interlayer cross-linking and pore setting: The woven fabric is pre-set and interlayer cross-linked, and the cross-linking morphology of the four-layer structure and the pore structure of the fabric are fixed by heat setting process. S5. Finishing: The finished fabric is then washed, softened and shaped, and dried in sequence to obtain the finished biofunctional composite fabric. The fabric is then cut and sewn to obtain the target textile body.

[0012] By adopting the above technical solution, specific modified fibers are first prepared for the positioning of different functional layers, rather than general modified fibers. This allows for the adjustment of the types and proportions of functional components according to the functional requirements of each layer, avoiding mutual interference between different functional components. Combined with melt blending and bonding grafting processes, the functional components and fiber-forming polymers form a stable integrated structure, ensuring the bonding strength of functional components from the fiber preparation stage. Layered yarn preparation and batch warping provide precisely matched yarn raw materials for subsequent integrated layered weaving, ensuring that the functional properties and yarn tension of each layer meet the design requirements. Integrated layered weaving uses the multi-warp beam warp feeding system of a multi-arm rapier loom to control the warp feed amount and weft interlacing pattern of the four layers, completing the four layers simultaneously in the same weaving process. The integrated weaving structure, along with the real-time adjustment of the modified fiber feeding ratio at preset warp-targeting functional areas via an electronic warp feeding system, directly forms a dot matrix warp-targeting functional area and a gradient-decreasing weaving structure without interrupting the weaving process. This achieves one-step forming of the fabric structure and functional distribution, eliminating the need for subsequent coating, printing, lamination, and other secondary processing. This significantly simplifies the production process and avoids damage to the fiber structure and fabric performance caused by secondary processing. The two-step setting process first eliminates the internal stress of the yarn generated during weaving, and then fixes the interlayer cross-linking structure and pore morphology of the fabric, ensuring the long-term stability of the fabric's dimensions and performance. The finishing process removes residual oils and impurities from the production process, optimizes the fabric's skin-friendly feel, and finally yields a finished fabric that meets the design requirements.

[0013] Preferably, in step S1, the mass ratio of the functional component to the fiber-forming polymer chips is 3:97 to 12:88, the operating temperature of the twin-screw extruder is 220°C to 285°C, the screw speed is 280 r / min to 450 r / min, and the spinning speed is 800 m / min to 1500 m / min; the fiber-forming polymer chips are any one of polyester chips, polyamide chips, and regenerated cellulose chips, and the linear density of the modified fiber obtained is 1.1 dtex to 7.8 dtex.

[0014] By adopting the above technical solution, the ratio range of functional components to fiber-forming polymer chips is determined based on the balance between the dispersibility of functional powder, fiber spinnability, and functional effects. Too low an addition amount cannot achieve stable functional effects, while too high an addition amount will affect the rheological properties of the polymer melt, leading to increased fiber breakage and fuzz during spinning, and a decrease in fiber mechanical properties, failing to meet subsequent weaving requirements. The temperature parameters of the twin-screw extruder are matched with the melting temperature range of the fiber-forming polymer, ensuring that the polymer is fully melted while avoiding high-temperature decomposition and failure of functional components. The screw speed setting ensures that the functional powder is uniformly dispersed in the polymer melt, avoiding uneven fiber performance caused by powder agglomeration. The spinning speed is coordinated with the stretching and setting processes to precisely control the linear density and crystallinity of the modified fiber, ensuring that the fiber's breaking strength, elongation, and other mechanical properties meet the requirements of textile processing. The selection of different fiber-forming polymer chips is adapted to the differentiated needs of different products such as waist supports, socks, and neck supports for strength, abrasion resistance, skin-friendliness, and environmental protection, expanding the applicable product range of this technical solution.

[0015] Preferably, in step S2, the twist coefficient of the twisting is set to 320 to 480, the warping tension is controlled to 15cN to 35cN, and the warping linear speed is controlled to 200m / min to 400m / min; the skin-friendly base fiber is any one of cotton fiber, modal fiber, or lyocell fiber, and the mass percentage of modified fiber in the yarns of the first functional layer, the second functional layer, and the outer solid layer is 15% to 45%.

[0016] By adopting the above technical solutions, the twist coefficient is set according to the fiber type and linear density of different yarns. A suitable twist coefficient can enable the fibers in the yarn to form a stable cohesion, improve the breaking strength and evenness of the yarn, and reduce yarn breakage and pilling problems during the weaving process. The tension and speed control of the warping process can ensure that the tension of each warp yarn on the same warp beam is consistent, and the tension of the warp yarns between different warp beams is matched with each other, providing a stable warp foundation for subsequent integrated layered weaving and avoiding weaving defects such as uneven tension and weft skew on the fabric surface. The skin-friendly base fibers are all skin-friendly fibers commonly used in close-fitting textiles, with good moisture absorption and wicking properties and a soft hand feel, which are suitable for the comfort needs of long-term close-fitting wear. The mass ratio range of modified fibers in each functional layer yarn can balance the basic textile performance and functional effect of the yarn, and can be flexibly adjusted according to the functional requirements of different products.

[0017] Preferably, in step S3, the loom speed is set to 220 r / min to 380 r / min, and the weaving warp and weft density is set to 300 threads / 10cm to 550 threads / 10cm. During the weaving process of the meridian-targeted functional area, with the acupoint projection center as the origin, the feeding ratio of modified fibers relative to the acupoint projection center is reduced by 5% to 15% for every 1cm to 3cm extension along the meridian direction, forming a gradient decreasing dot matrix weaving structure.

[0018] By adopting the above technical solutions, the loom speed and weaving warp and weft density are matched to each other, adapting to the weaving difficulty of four-layer integrated interlacing, avoiding problems such as inaccurate interlacing and yarn breakage caused by excessive speed. The setting of warp and weft density directly determines the basic weight, thickness, porosity and mechanical properties of the fabric, which can be flexibly adjusted according to the usage scenarios of different products such as waist support, socks, and neck support. The dynamic adjustment of the modified fiber feeding ratio is achieved through the combination of the loom's electronic jacquard and multi-weft feeding system. When the fabric is woven to the area corresponding to the preset meridian acupoints, the interlacing ratio of modified fiber yarn and ordinary fiber yarn is adjusted in real time, thereby achieving a gradient change in the mass ratio of modified fiber and simultaneously forming a gradient decreasing dot matrix weaving structure. The design of reducing the feeding ratio by 5% to 15% every 1cm to 3cm along the meridian direction can match the circulation length and direction of different meridians, flexibly adjust the magnitude of gradient change, and achieve precise matching between the distribution of dot matrix functional units and the meridian circulation path.

[0019] Preferably, in step S4, the setting temperature is set to 120°C to 180°C, the setting time is set to 30s to 90s, and the fabric overfeed rate is controlled at 2% to 8%; the pre-setting temperature is set to 100°C to 130°C, the pre-setting time is set to 20s to 45s, the warp tension of the fabric is controlled at 500N to 1200N during the setting process, and the porosity of the fabric is stabilized at 35% to 65% after setting.

[0020] By adopting the above technical solutions, the setting of the setting temperature and time is matched with the glass transition temperature of the fiber-forming polymer, allowing the fiber molecular chains to rearrange under thermal action, eliminating internal stress, and fixing the fabric's structure and dimensions. The setting of the overfeed rate can regulate the weft shrinkage rate and surface smoothness of the fabric, while also providing auxiliary control over the fabric's porosity. The pre-setting process uses low-temperature short-time treatment to initially stabilize the basic structure of the fabric, eliminate internal stress generated during weaving, and avoid uneven fabric surface and unstable width caused by uneven release of internal stress during the main setting process. The precise control of the warp tension can ensure the consistency of the fabric's warp dimensions during the setting process and avoid uneven stretching. Through the combination of the pre-setting and main setting processes, the fabric's porosity can be precisely stabilized within the design range of 35% to 65%, ensuring the long-term stability of the fabric's breathability and functional conductivity.

[0021] Preferably, in step S5, the washing temperature is controlled at 40℃ to 60℃, the drying temperature is controlled at 80℃ to 110℃, and the drying time is set to 8min to 20min; the softening and shaping uses a formaldehyde-free skin-friendly softener, the amount of softener is 1% to 3% of the fabric weight, no finishing agents containing formaldehyde or heavy metals are added during the treatment process, and the pH value of the finished fabric is controlled at 5.5 to 7.0.

[0022] By adopting the above technical solutions, the setting of washing temperature and drying parameters can effectively remove impurities such as spinning oils and sizing agents adhering to the fabric during weaving and finishing processes, without damaging the bonding and grafting structure of the functional components inside the fiber, thus avoiding damage to the fabric's structure and fiber properties. The use of formaldehyde-free skin-friendly softener optimizes the soft feel of the fabric without introducing harmful chemicals, meeting the safety standards for close-fitting textiles. No finishing agents containing formaldehyde or heavy metals are added during the processing, controlling harmful substance residues in the product from the source of the process and ensuring the product's biosafety. The pH value of the finished fabric is controlled within the range of 5.5 to 7.0, which is compatible with the acid-base environment of human skin, avoiding irritation to the skin barrier from long-term close-fitting wear. Combined with the aforementioned fiber-level blending modification and bonding grafting process, the finished fabric can achieve the performance requirement that the functional component retention rate is not less than 95% after 150 standard washes.

[0023] Thirdly, this application provides a method of using a multifunctional bio-textile based on traditional Chinese medicine, employing the following technical solution: A method for using a multifunctional bio-functional textile based on traditional Chinese medicine includes the following steps: selecting a textile body with a corresponding meridian-targeting functional area according to the target meridian and acupoint area of ​​the human body; wearing the textile body on the target body surface, so that the dot matrix action unit of the meridian-targeting functional area is completely aligned with the surface projection of the target meridian and acupoint of the human body; maintaining continuous contact between the bio-functional composite fabric and the human body surface, with a daily continuous wearing time of not less than 6 hours.

[0024] By adopting the above technical solution, and selecting textile bodies with corresponding meridian-targeting functional areas based on the target meridians and acupoints of the human body, it is possible to ensure that the dot matrix action units of the meridian-targeting functional areas accurately correspond to the conditioning target points, avoiding the decrease in efficiency caused by the positional deviation of the functional areas. When wearing the product, the position is adjusted so that the dot matrix action units of the meridian-targeting functional areas are completely aligned with the surface projection of the target meridians and acupoints of the human body, which can minimize the air gap between the fabric and the skin and ensure the efficient transmission of functional effects to the human body surface. Maintaining continuous contact between the biofunctional composite fabric and the human body surface, combined with a daily wearing time of no less than 6 hours, can achieve continuous and stable intervention of functional effects without additional time and operating costs. It can be adapted to various daily scenarios such as office, home, commuting, and light exercise, integrating health conditioning into the daily wearing process and improving long-term use compliance.

[0025] In summary, this application has the following beneficial effects: 1. This application adopts a four-layer structure consisting of an inner skin-friendly layer, a first functional layer, a second functional layer, and an outer foundation layer. Through an integrated weft-and-weft interlacing, a porous cross-linked composite structure is formed, simultaneously creating a porous conduction channel that runs through all four layers. At the same time, a meridian-targeting functional area corresponding to the surface projection of human meridian acupoints is set up. A matrix arrangement of dots matching the meridian acupoints is used to achieve targeted enrichment of modified fibers, ensuring the synergistic conduction and precise targeting effect of each layer.

[0026] 2. In this application, fiber-grade blending modification combined with bonding grafting method is preferred, so that the functional components of each functional layer form an integral fixed structure with the fiber body of the fiber-forming polymer. This is different from the conventional surface coating and impregnation process, which avoids the loss and migration of functional components from the source of fiber forming, ensures the long-term stability of product function, and reduces the risk of skin irritation caused by auxiliary agent residue.

[0027] 3. The preparation method of this application uses an integrated layered weaving process on a multi-arm rapier loom to simultaneously complete the integrated interweaving of four layers; at the same time, by dynamically adjusting the feeding ratio of modified fibers during the weaving process, the differentiated forming of the dot matrix warp-guided targeted functional area and the gradient decreasing weaving structure is achieved in one step, which simplifies the production process while ensuring the stability of the interlayer structure and the accuracy of the functional distribution of the fabric.

[0028] 4. The preparation method of this application uses a two-step heat setting process that combines pre-setting and interlayer cross-linking setting to precisely fix the interlayer cross-linking morphology and overall pore structure of the fabric. Combined with a formaldehyde-free, skin-friendly, and biosafe finishing process, the pH range of the finished fabric is precisely controlled to ensure the fabric's dimensional stability, wearing comfort, and biocompatibility, making it suitable for long-term close-fitting use.

[0029] 5. The method of use of this application involves selecting corresponding textiles by matching the target meridians and acupoints of the human body, so that the dot matrix action units of the meridian-targeting functional area are precisely aligned with the acupoint surface projection. Through continuous daily wear, the function is stabilized, greatly improving the compliance of the conditioning process and adapting to the daily use needs of multiple scenarios. Attached Figure Description

[0030] Figure 1 This is a flowchart of a preparation method for a multifunctional bio-textile based on traditional Chinese medicine, provided in this application. Detailed Implementation

[0031] The present application will be further described in detail below with reference to embodiments and comparative examples. Unless otherwise specified, the experimental methods used below are conventional methods. Unless otherwise specified, the materials, reagents, methods and instruments used are all conventional materials, reagents, methods and instruments in the art, which can be obtained by those skilled in the art through commercial channels or prepared according to literature methods.

[0032] Technical Concept: With the increasing popularity of the TCM concept of "prevention of disease" in daily health interventions, wearable health textiles have become an important carrier for daily conditioning of sub-healthy individuals, and their application scenarios continue to expand. However, existing related products still have significant technical shortcomings. Most existing products use a design that uniformly loads functional materials across the entire fabric, failing to incorporate the distribution characteristics of TCM meridians and acupoints for precise and differentiated layout. They lack targeted structural designs that match the pathways of meridians, resulting in low utilization of functional materials and difficulty in achieving the meridian-based conditioning effects consistent with TCM theory. Some multi-layered functional products use a process of first weaving and then hot-pressing composite, which fails to form a functional conduction channel that connects multiple layers. This not only results in insufficient synergy between functional layers but also leads to poor fabric breathability and easy delamination between layers. Furthermore, most products load functional components through surface coating and impregnation finishing processes, where the functional components only adhere to the fiber surface. These components are easily detached and weakened during washing and wearing, and there is also a risk of skin irritation caused by residual additives.

[0033] This application addresses the core pain points of existing technologies by employing a four-layer, layered, integrated warp and weft weaving structure. Through synchronous weaving, a porous, cross-linked composite structure with interconnected conductive channels is formed, ensuring long-term stability of interlayer bonding while achieving synergistic transmission of functions across each layer. Targeted functional zones corresponding to the surface projection of acupoints along the meridians are incorporated, using a matrix arrangement of dots matching the acupoints and a gradient-decreasing weaving structure along the meridian pathways, aligning with the design principles of traditional Chinese medicine's meridian-based conditioning. Simultaneously, a fiber-level blending modification combined with bonding grafting method allows functional components to form a stable, integrated structure with the fiber body. Combined with a process that dynamically adjusts the feeding ratio of modified fibers during integrated layered weaving, a differentiated functional structure is formed in one step, balancing the product's targeted precision, long-lasting functionality, wearing comfort, and biosafety.

[0034] Example 1: This example provides a multifunctional bio-functional textile based on the TCM concept of preventing disease, specifically a multifunctional bio-functional waist support suitable for waist and abdomen conditioning. It focuses on meridian warming and nourishing, and harmonizing Qi and blood. It is suitable for daily wear by people who sit for long periods at work, those who are afraid of cold in their waist and abdomen, and those who are undergoing postpartum gentle conditioning. The product includes a textile body woven from a bio-functional composite fabric. The core material of the finished lumbar support is also a bio-functional composite fabric. From the inside out, the fabric consists of an inner skin-friendly layer, a first functional layer, a second functional layer, and an outer foundation layer. These four layers are interwoven to form a porous cross-linked composite structure, simultaneously creating porous conduction channels that connect all four layers. This ensures synergistic conduction of functions across each layer while maintaining the fabric's breathability and moisture-wicking properties. The fabric features targeted functional zones that precisely correspond to acupoints on the body's lower back, such as the Mingmen, Shenshu, Qihai, and Guanyuan acupoints. These targeted functional zones are arranged in a matrix of dots matching the acupoints, allowing for the directional release of heat energy that penetrates inwards to the body surface. Within these targeted functional zones, the proportion of modified fibers in the first, second, and outer foundation layers is 3.5 times that of the corresponding non-functional layers, achieving functional enrichment and targeted action at the acupoint locations.

[0035] Within the meridian-targeting functional area, with the center of the acupoint projection on the body surface as the origin, the mass ratio of modified fibers decreases in a gradient along the direction of the corresponding meridian, forming a gradient woven conduction belt extending along the meridian. The gradient woven conduction belt adopts a gradient arrangement of dots matrix matching the Du meridian and Dai meridian circulation paths to achieve the meridian-warming and nourishing effect along the Du meridian and Dai meridian.

[0036] The functional components in the first functional layer, the second functional layer, and the outer solid layer are all integrated with the fiber-forming polymer fiber body through fiber-level blending modification and bonding grafting, which prevents the functional components from falling off and migrating, and ensures the stability and safety of long-term wear. The overall porosity of the biofunctional composite fabric is 50%, which takes into account both the breathability and functional conduction efficiency of close-fitting wear.

[0037] The preparation method of the above-mentioned multifunctional bio-functional textiles based on the TCM concept of disease prevention includes the following steps: S1. Preparation of functional modified fibers: First modified fibers for the first functional layer, second modified fibers for the second functional layer, and third modified fibers for the outer solid layer are prepared respectively; the functional components corresponding to each modified fiber are uniformly mixed with fiber-forming polymer chips in a preset ratio, and then melt-blended and bonded by a twin-screw extruder. After spinning, stretching, and setting processes, the modified fibers corresponding to each layer are obtained. The mass ratio of functional components to fiber-forming polymer chips is 7.5:92.5. The operating temperature of the twin-screw extruder is 252.5℃, the screw speed is 365r / min, and the spinning speed is 1150m / min. The fiber-forming polymer chips are made of polyester chips, and the linear density of the modified fiber is 4.45dtex, which is suitable for the weaving strength and softness requirements of the waist support fabric.

[0038] S2, Layered Yarn Doubling and Warping: For the four-layer structure of biofunctional composite fabric, weaving yarns corresponding to each layer are prepared separately. The corresponding modified fibers and skin-friendly base fibers are doubling and twisted according to the design ratio to obtain special yarns for each layer. Then, the special yarns for each layer are warped in batches to ensure uniform warp tension in subsequent weaving. The twist coefficient is set to 400, the warping tension is controlled at 25cN, and the warping speed is controlled at 300m / min. The skin-friendly base fiber is Modal fiber, which takes into account both skin-friendly feel and moisture absorption and wicking properties. The modified fiber accounts for 30% of the mass of the yarn in the first functional layer, the second functional layer and the outer solid layer.

[0039] S3. Differentiated Layered Weaving and Meridian Targeting Zone Formation: A multi-arm rapier loom is used for integrated layered weaving. According to the four-layer structure layout design, the inner skin-friendly layer, the first functional layer, the second functional layer, and the outer foundation layer are interwoven and woven simultaneously. At the same time, at the preset meridian targeting functional zone position, the feeding ratio of modified fibers is dynamically adjusted to complete the differentiated weaving of the dot matrix meridian targeting functional zone and the gradient decreasing weaving structure, so as to realize the functional differentiation design between the acupoint area and the non-functional area. The loom speed is set to 300 r / min, and the weaving warp and weft density is set to 425 threads / 10cm. During the weaving process of the meridian-targeted functional area, with the acupoint projection center as the origin, the proportion of modified fiber fed relative to the acupoint projection center is reduced by 10% for every 2cm extension along the meridian, forming a gradient decreasing dot matrix weaving structure to match the design requirements of meridian-based warming.

[0040] S4. Interlayer cross-linking and pore setting: The woven fabric is pre-set and interlayer cross-linked, and the cross-linking morphology and pore structure of the four-layer structure are fixed by heat setting process to stabilize the dimensional stability and functional transmission structure of the fabric. The setting temperature is set at 150℃, the setting time is set at 60s, and the fabric overfeed rate is controlled at 5%; the pre-setting temperature is set at 115℃, the pre-setting time is set at 32.5s, the warp tension of the fabric is controlled at 850N during the setting process, and the porosity of the fabric is stabilized at 50% after setting.

[0041] S5. Finishing: The shaped fabric undergoes a bio-safe finishing process, including washing, softening and shaping, and drying, to remove residual impurities from the fabric weaving process, optimize the skin-friendly feel of the fabric, and produce a finished bio-functional composite fabric. The fabric is then cut and sewn to produce the target waist support product. The washing temperature is controlled at 50℃, the drying temperature at 95℃, and the drying time at 14 minutes. The softening and shaping process uses a formaldehyde-free, skin-friendly softener, with the amount of softener being 2% of the fabric weight. No finishing agents containing formaldehyde or heavy metals are added during the process. The pH value of the finished fabric is controlled at 6.25, which is in line with the slightly acidic environment of human skin and suitable for long-term close-fitting wear. After 150 standard washes, the functional component retention rate of the finished fabric is not less than 95%, and it can maintain stable functional effects even after long-term wear and washing.

[0042] The method of using the multifunctional bio-functional textile based on traditional Chinese medicine's preventive medicine approach provided in this embodiment includes the following steps: Select the waist support product of this embodiment according to the Du meridian, Dai meridian and corresponding acupoints in the waist and abdomen area to be regulated; Wear the waist support on the waist and abdomen area, adjust the tightness and position of the wearer so that the dot matrix action unit of the meridian-targeting functional area on the fabric is completely in contact with the surface projection of the target meridian acupoints such as Mingmen, Shenshu, Qihai, and Guanyuan; Maintain continuous contact between the inner side of the fabric and the skin of the waist and abdomen during the wearing process, and wear it continuously for no less than 6 hours a day. It can be used in various scenarios such as daily office work, home rest, light exercise, and commuting. Continuous wear can achieve a stable meridian-regulating effect.

[0043] Example 2: This example provides a multifunctional bio-functional textile based on the TCM concept of preventing disease, specifically a multifunctional bio-functional health sock adapted for foot care. It focuses on warming and ventilating the feet, inhibiting bacteria and deodorizing, and improving microcirculation. It is suitable for daily wear by people who have cold feet, sweat easily and have odor, or who commute for long periods. The product includes a textile body woven from a bio-functional composite fabric. The core material of the finished health socks is also a bio-functional composite fabric, which consists of an inner skin-friendly layer, a first functional layer, a second functional layer, and an outer foundation layer, arranged sequentially from the inside out. These four layers are interwoven to form a porous cross-linked composite structure, simultaneously creating porous conduction channels that connect all four layers, balancing breathability and sweat-wicking requirements with functional conduction efficiency. The fabric features meridian-targeting functional zones that precisely correspond to acupoints such as Yongquan, Taixi, and Sanyinjiao on the feet. These zones are arranged in a matrix of dots matching the acupoints on the feet, allowing for the directional release of heat energy that penetrates inwards to the body surface. Within these meridian-targeting functional zones, the proportion of modified fibers in the first, second, and outer foundation layers is twice that of the corresponding non-functional layers of the fabric, achieving targeted action on key acupoints on the feet.

[0044] Within the meridian-targeting functional area, with the center of the acupoint projection on the body surface as the origin, the mass ratio of modified fibers decreases gradually along the direction of the corresponding meridian, forming a gradient woven conduction belt extending along the meridian. The gradient woven conduction belt adopts a gradient arrangement of dots matrix that matches the meridian circulation path of the foot, thereby achieving the meridian-warming and nourishing effect of the foot meridian.

[0045] The functional components in the first functional layer, the second functional layer, and the outer solid layer are all integrated with the fiber-forming polymer fiber body through fiber-level blending modification and bonding grafting, forming an integral fixed structure that is water-resistant and abrasion-resistant, suitable for the high-frequency wearing and washing of socks; the overall porosity of the biofunctional composite fabric is 35%, taking into account both abrasion resistance and breathability for foot wear.

[0046] The preparation method of the above-mentioned multifunctional bio-functional textiles based on the TCM concept of disease prevention includes the following steps: S1. Preparation of functional modified fibers: First modified fibers for the first functional layer, second modified fibers for the second functional layer, and third modified fibers for the outer solid layer are prepared respectively; the functional components corresponding to each modified fiber are uniformly mixed with fiber-forming polymer chips in a preset ratio, and then melt-blended and bonded by a twin-screw extruder. After spinning, stretching, and setting processes, the modified fibers corresponding to each layer are obtained. The mass ratio of functional components to fiber-forming polymer chips is 3:97. The operating temperature of the twin-screw extruder is 220℃, the screw speed is 280r / min, and the spinning speed is 800m / min. The fiber-forming polymer chips are made of polyamide chips, and the linear density of the modified fiber is 1.1dtex, which is suitable for the softness, abrasion resistance and high elasticity requirements of sock fabrics.

[0047] S2, Layered Yarn Doubling and Warping: For the four-layer structure of biofunctional composite fabric, weaving yarns corresponding to each layer are prepared separately. The corresponding modified fibers and skin-friendly basic fibers are doubled and twisted according to the design ratio to obtain special yarns for each layer. Then, the special yarns for each layer are warped in batches to ensure that the warp tension of the subsequent weaving is uniform and stable. The twist coefficient is set to 320, the warping tension is controlled at 15cN, and the warping speed is controlled at 200m / min. The skin-friendly base fiber is made of cotton fiber, which is suitable for the skin-friendly and moisture-wicking needs of footwear. The modified fiber accounts for 15% of the mass of the yarns in the first functional layer, the second functional layer, and the outer solid layer.

[0048] S3. Differentiated Layered Weaving and Meridian Targeting Zone Formation: A multi-arm rapier loom is used for integrated layered weaving. According to the four-layer structure layout design, the inner skin-friendly layer, the first functional layer, the second functional layer, and the outer foundation layer are interwoven and woven simultaneously. At the same time, at the preset meridian targeting functional zone position, the feeding ratio of modified fibers is dynamically adjusted to complete the differentiated weaving of the dot matrix meridian targeting functional zone and the gradient decreasing weaving structure, so as to realize the functional differentiation design between the acupoint area and the non-functional area. The loom speed is set to 220 r / min, and the weaving warp and weft density is set to 300 threads / 10cm. During the weaving process of the meridian-targeted functional area, with the acupoint projection center as the origin, the proportion of modified fiber fed relative to the acupoint projection center is reduced by 5% for every 1cm extension along the meridian, forming a gradient decreasing dot matrix weaving structure to match the meridian-guided warming and nourishing needs of the foot meridian.

[0049] S4. Interlayer cross-linking and pore setting: The woven fabric is pre-set and interlayer cross-linked. The cross-linking morphology of the four-layer structure and the pore structure of the fabric are fixed by heat setting process to stabilize the dimensional stability of the fabric and prevent the socks from shrinking and deforming after washing. The setting temperature is set at 120℃, the setting time is set at 30s, and the fabric overfeed rate is controlled at 2%; the pre-setting temperature is set at 100℃, the pre-setting time is set at 20s, the warp tension of the fabric is controlled at 500N during the setting process, and the porosity of the fabric is stabilized at 35% after setting.

[0050] S5. Finishing: The shaped fabric undergoes a biosafe finishing process, including washing, softening and shaping, and drying, to remove residual impurities from the fabric weaving process, optimize the skin-friendly and soft feel of the fabric, and produce a finished biofunctional composite fabric. The fabric is then cut and sewn to produce the target health sock product. The washing temperature is controlled at 40℃, the drying temperature is controlled at 80℃, and the drying time is set at 8 minutes. The softening and shaping uses a formaldehyde-free skin-friendly softener, with the amount of softener being 1% of the fabric weight. No finishing agents containing formaldehyde or heavy metals are added during the process. The pH value of the finished fabric is controlled at 5.5, which is in line with the slightly acidic environment of human skin and suitable for long-term close-fitting footwear. After 150 standard washes, the functional component retention rate of the finished fabric is not less than 95%, making it suitable for the daily use scenario of high-frequency washing of socks.

[0051] The method of using the multifunctional bio-functional textile based on traditional Chinese medicine for disease prevention provided in this embodiment includes the following steps: Select the health sock product of this embodiment according to the meridians and corresponding acupoints on the human foot to be regulated; wear the health sock normally on the foot, adjust the position of the sock so that the dot matrix action unit of the meridian-targeting functional area on the fabric is completely aligned with the surface projection of the target meridian acupoints such as Yongquan and Taixi; keep the inner side of the fabric in continuous contact with the skin of the foot during the wearing process, and wear it continuously for no less than 6 hours a day. It can be used for all scenarios such as daily commuting, walking and exercise, and resting at home. It can still maintain stable functional effects after high-frequency washing.

[0052] Example 3: This example provides a multifunctional bio-functional textile based on the TCM concept of disease prevention, specifically a multifunctional bio-functional neck protector suitable for neck and shoulder conditioning. It focuses on warming and relieving neck and shoulder discomfort, dispelling cold, and soothing along the meridians. It is suitable for people who work at a desk for long periods, experience neck and shoulder stiffness due to cold, and require daily protection in air-conditioned rooms. The product includes a textile body woven from a bio-functional composite fabric. The core material of the finished neck brace is also a bio-functional composite fabric, which consists of an inner skin-friendly layer, a first functional layer, a second functional layer, and an outer foundation layer, arranged sequentially from the inside out. These four layers are interwoven to form a porous cross-linked composite structure, simultaneously creating porous conduction channels that connect all four layers, ensuring both breathability and comfort when worn close to the neck and shoulders, as well as efficient functional conduction. The fabric features meridian-targeting functional zones that precisely correspond to acupoints such as Dazhui, Fengchi, and Jianjing on the neck and shoulders. These zones are arranged in a matrix of dots matching the acupoints on the neck and shoulders, allowing for the directional release of heat energy that penetrates inwards to the body surface. Within these meridian-targeting functional zones, the modified fiber mass ratio in the first, second, and outer foundation layers is five times that of the modified fiber mass ratio in the non-functional layers of the fabric, achieving a high-intensity targeted effect on key acupoints in the neck and shoulders.

[0053] Within the meridian-targeting functional area, with the center of the acupoint projection on the body surface as the origin, the mass ratio of modified fibers decreases in a gradient along the direction of the corresponding meridian, forming a gradient woven conduction belt extending along the meridian. The gradient woven conduction belt adopts a gradient arrangement of dots matrix that matches the meridian pathway of the neck and shoulders, thereby achieving the meridian-guided warming and soothing effect of the neck and shoulders.

[0054] The functional components in the first functional layer, the second functional layer, and the outer solid layer are all integrated with the fiber-forming polymer fiber body through fiber-level blending modification and bonding grafting, ensuring long-term functional stability and eliminating the risk of additive shedding. The overall porosity of the biofunctional composite fabric is 65%, which meets the breathability requirements of the neck and shoulder area and does not cause stuffiness even after long-term wear.

[0055] The preparation method of the above-mentioned multifunctional bio-functional textiles based on the TCM concept of disease prevention includes the following steps: S1. Preparation of functional modified fibers: First modified fibers for the first functional layer, second modified fibers for the second functional layer, and third modified fibers for the outer solid layer are prepared respectively; the functional components corresponding to each modified fiber are uniformly mixed with fiber-forming polymer chips in a preset ratio, and then melt-blended and bonded by a twin-screw extruder. After spinning, stretching, and setting processes, the modified fibers corresponding to each layer are obtained. The mass ratio of functional components to fiber-forming polymer chips is 12:88. The operating temperature of the twin-screw extruder is 285℃, the screw speed is 450r / min, and the spinning speed is 1500m / min. The fiber-forming polymer chips are made from regenerated cellulose chips, and the linear density of the modified fiber is 7.8dtex, which is suitable for the soft, skin-friendly, and drape requirements of neck support fabrics.

[0056] S2, Layered Yarn Doubling and Warping: For the four-layer structure of biofunctional composite fabric, weaving yarns corresponding to each layer are prepared separately. The corresponding modified fibers and skin-friendly basic fibers are doubled and twisted according to the design ratio to obtain special yarns for each layer. Then, the special yarns for each layer are warped in batches to ensure that the warp tension is uniform and the fabric is formed smoothly in subsequent weaving. The twist coefficient is set to 480, the warping tension is controlled at 35cN, and the warping speed is controlled at 400m / min. The skin-friendly base fiber is Lyocell fiber, which has the advantages of being extremely skin-friendly, moisture-wicking and breathable, and environmentally friendly. The modified fiber accounts for 45% of the mass of the yarn in the first functional layer, the second functional layer and the outer solid layer.

[0057] S3. Differentiated Layered Weaving and Meridian Targeting Zone Forming: A multi-arm rapier loom is used for integrated layered weaving. According to the four-layer structure layout design, the inner skin-friendly layer, the first functional layer, the second functional layer, and the outer foundation layer are interwoven and woven simultaneously. At the same time, at the preset meridian targeting functional zone position, the feeding ratio of modified fibers is dynamically adjusted to complete the differentiated weaving of the dot matrix meridian targeting functional zone and the gradient decreasing weaving structure, so as to realize the high-strength functional differentiation design between the acupoint area and the non-functional area. The loom speed is set to 380 r / min, and the weaving warp and weft density is set to 550 threads / 10cm. During the weaving process of the meridian-targeted functional area, with the acupoint projection center as the origin, the proportion of modified fiber fed relative to the acupoint projection center is reduced by 15% for every 3cm extension along the meridian, forming a gradient decreasing dot matrix weaving structure to match the meridian-guided warming and nourishing needs of the neck and shoulder meridians.

[0058] S4. Interlayer cross-linking and pore setting: The woven fabric is pre-set and interlayer cross-linked. The cross-linking morphology and pore structure of the four-layer structure are fixed by heat setting process, which stabilizes the dimensional stability and functional transmission structure of the fabric and avoids structural deformation after long-term wear and washing. The setting temperature is set at 180℃, the setting time is set at 90s, and the fabric overfeed rate is controlled at 8%; the pre-setting temperature is set at 130℃, the pre-setting time is set at 45s, the warp tension of the fabric is controlled at 1200N during the setting process, and the porosity of the fabric is stabilized at 65% after setting.

[0059] S5. Finishing: The shaped fabric undergoes a bio-safe finishing process, including washing, softening and setting, and drying, to remove residual impurities from the fabric weaving process, optimize the skin-friendly and soft feel of the fabric, and produce a finished bio-functional composite fabric. The fabric is then cut and sewn to produce the target neck protection product. The washing temperature is controlled at 60℃, the drying temperature at 110℃, and the drying time at 20 minutes. A formaldehyde-free, skin-friendly softener is used for softening and shaping, with the softener amounting to 3% of the fabric weight. No finishing agents containing formaldehyde or heavy metals are added during the process. The pH value of the finished fabric is controlled at 7.0, conforming to the slightly acidic environment of human skin and suitable for long-term close-fitting wear on the neck and shoulders. After 150 standard washes, the functional component retention rate of the finished fabric is no less than 95%, maintaining stable functional effects even after long-term wear and washing.

[0060] The method of using the multifunctional bio-functional textile based on traditional Chinese medicine for disease prevention provided in this embodiment includes the following steps: Select the neck support product of this embodiment according to the meridians and corresponding acupoints to be regulated in the neck and shoulder area; Wear the neck support on the neck and shoulder area, adjust the wearing position and tightness so that the dot matrix action units of the meridian-targeting functional area on the fabric are completely in contact with the surface projection of the target meridian acupoints such as Dazhui, Fengchi, and Jianjing; Keep the inner side of the fabric in continuous contact with the skin of the neck and shoulders during the wearing process, and wear it continuously for no less than 6 hours a day. It can be used in various scenarios such as office work, home rest, business travel, and air-conditioned room protection to achieve continuous meridian regulation of the neck and shoulder area.

[0061] Comparative Example 1: The only difference between this comparative example and Example 1 is that: within the meridian-targeting functional area, the gradient decreasing design of modified fibers along the meridian direction is eliminated, and the mass ratio of modified fibers in the entire meridian-targeting functional area is the highest ratio at the acupoint center, without gradient woven conduction belts; the total amount of functional components, other structures and process parameters are completely consistent with Example 1.

[0062] Comparative Example 2: The only difference between this comparative example and Example 1 is that the differentiated design of the meridian-targeting functional area is cancelled. In the first functional layer, the second functional layer, and the outer solidification layer of the full-width fabric, the mass ratio of modified fiber is the same as the basic ratio of non-functional area in Example 1, and there is no acupoint enrichment area. The total amount of functional components, the remaining structure and process parameters are completely consistent with Example 1.

[0063] Comparative Example 3: The only difference between this comparative example and Example 1 is that the four-layer integrated warp and weft interlacing structure is cancelled and replaced with the conventional three-layer separate weaving and lamination structure; the inner skin-friendly base fabric, the single-function base fabric, and the outer protective base fabric are woven separately, and the three base fabrics are hot-pressed and laminated with hot melt adhesive, without the through-pore conduction channel formed by the integrated interlacing; the total amount of functional components, the design of the warp-guided target area, and the other process parameters are completely consistent with Example 1.

[0064] Comparative Example 4: The only difference between this comparative example and Example 1 is that the fiber-level blending modification process in step S1 is omitted, and all functional layers are woven from ordinary polyester fibers. After the base fabric is woven, the conventional impregnation finishing process of existing technology is used to load an equal amount of functional components from Example 1 onto the fiber surface. The loading of functional components is increased by local printing in the targeted functional areas along the warp, matching the enrichment ratio of Example 1. The remaining structure, product form, and total raw material usage are completely consistent with Example 1.

[0065] Comparative Example 5: The only difference between this comparative example and Example 1 is that it adopts the existing mainstream far-infrared health care waist support solution, the fabric is ordinary cotton-polyester blended fabric, and the basic health care function is achieved by coating the surface with far-infrared ceramic powder and antibacterial agent; there is no layered functional structure, no meridian-targeting functional area, no gradient weaving design, and no fiber-level blending modification, and only the product size and shape are the same as Example 1.

[0066] I. Far-infrared targeting performance test: Referring to GB / T30127-2013 "Detection and evaluation of far-infrared performance of textiles", far-infrared performance and targeting effect test were carried out. Samples to be tested were prepared for Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, Comparative Example 3, Comparative Example 4, and Comparative Example 5. For each sample, specimens were cut to the standard size at the acupoint center of the meridian targeting functional area, the meridian extension gradient area, and the non-functional area. All specimens were placed in a standard atmospheric environment with a temperature of 20℃ and a relative humidity of 65% for 24 hours to acclimate. The far-infrared normal emissivity of each specimen was tested using a far-infrared spectrometer. At the same time, the far-infrared radiation temperature rise index of the specimens was tested according to the standard method. The test data of different sampling positions of each sample were recorded completely.

[0067] II. Long-term stability test of wash resistance: Referring to GB / T8629-2017 "Home washing and drying procedures for testing textiles" and GB / T20944.3-2008 "Evaluation of antimicrobial properties of textiles - Part 3: Oscillation method", the stability test of wash resistance was carried out. Samples to be tested were prepared for Examples 1, 2, 3, Comparative Examples 1, 2, 3, 4, and 5. Three sets of parallel samples were prepared for each sample. The standard 5A washing program was adopted, and the washing temperature was set at 40℃. Each washing and drying cycle was considered a complete cycle. The far-infrared normal emissivity and antimicrobial properties of each sample were tested after 0, 50, 100, and 150 washing cycles. Staphylococcus aureus and Escherichia coli were used as test bacteria for antimicrobial performance testing. The performance test results of each sample after different washing cycles were fully recorded, and the retention rate of the corresponding functional indicators was calculated.

[0068] III. Fabric breathability and biosafety performance testing: Referencing GB / T5453-1997 "Determination of air permeability of textile fabrics", GB / T18401-2010 "National Basic Safety Technical Specifications for Textile Products", and GB / T16886.10-2017 "Biological evaluation of medical devices - Part 10: Irritation and skin sensitization tests", we conducted fabric breathability and biosafety performance tests. We prepared finished fabric samples for Examples 1, 2, 3, Comparative Examples 1, 2, 3, 4, and 5. All samples were placed in a standard atmospheric environment with a temperature of 20℃ and a relative humidity of 65% for 24 hours to acclimate. The air permeability of each sample was tested using a fabric breathability meter. The test pressure difference was set to 100 Pa, and the test area was set to 20 cm². Ten points were tested continuously for each sample, and the average value was taken. Simultaneously, according to the corresponding standards, the pH value, formaldehyde content, decomposable carcinogenic aromatic amine dye index, and skin irritation performance of each sample were tested sequentially. All test data were fully recorded.

The functional enrichment of the acupoint center and the gradient arrangement along the meridian direction can match the range of action designed by the meridian circulation path in traditional Chinese medicine, directly determining the targeted coverage mode of the fabric's functional effect.

[0070] As can be seen from Examples 1-3 and Comparative Example 2, and Table 1, the differentiated design of the meridian-targeting functional areas set for human meridian acupoints is the core structure for achieving targeted enrichment of functional materials. The differentiated arrangement of functional fibers in the acupoint-corresponding area and non-functional area directly affects the intensity of the local functional effect of the fabric, and is the key design for achieving precise acupoint action.

[0071] Based on Examples 1-3 and Comparative Example 3, and in conjunction with Tables 1 and 3, it can be seen that the porous cross-linked composite structure formed by the integrated warp and weft weaving of the four layers is the core factor affecting the synergistic transmission of fabric functions and breathability. The through-pore transmission channel formed by the integrated weaving can ensure the effective transmission of functions of each layer, and directly determines the breathability and comfort performance of the fabric. This structure has an essential difference in characteristics from the structure of layered weaving followed by heat pressing composite.

[0072] As can be seen from Examples 1-3 and Comparative Example 4, and Tables 2 and 3, the integrated fixed structure of functional components formed by fiber-level blending modification is a key process that determines the long-term stability of product functions and biosafety performance. The way functional components are combined with the fiber body of the fiber-forming polymer directly affects the retention rate of functional materials during the washing process, and is also directly related to the skin irritation risk of the fabric.

[0073] Based on Examples 1-3 and Comparative Example 5, and in conjunction with Tables 1, 2, and 3, it can be seen that the overall technical solution of layered functional design, warp-guided targeted weaving, and fiber-level blending modification adopted in this application has significant differences in technical path in terms of functional targeting, long-lasting effect, wearing comfort, and biosafety compared to the coating process and uniform fabric design of existing conventional health textiles. The core structures and processes form a synergistic effect of mutual cooperation.

[0074] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
