Description

Technical Field

[0001] The invention belongs to the field of textile science and engineering, and in particular relates to six-effect synergistic meridian conditioning multifunctional underwear and a preparation method thereof. Background Art

[0002] With the booming development of the healthcare industry in modern society, textiles with multiple health-related functions have gradually become a hot research topic in both scientific research and the market. In particular, underwear products that effectively regulate human physiological functions through the combination of multiple functional materials have attracted widespread attention. While existing functional underwear made with far-infrared fibers, magnetic therapy fibers, and various antimicrobial agents can achieve some basic health benefits, significant technical bottlenecks remain to be overcome in key areas such as precise targeting of meridian conditioning, synergistic effects of improving microcirculation, and the long-term practical performance of antimicrobial and antioxidant properties.

[0003] In the crucial area of ​​meridian conditioning and microcirculation improvement, traditional technical solutions suffer from two significant shortcomings: First, functional materials are mostly evenly dispersed across the fabric surface or between fibers, lacking precise targeting of key acupuncture points such as the Guanyuan and groin meridians. Consequently, the resulting magnetic field or far-infrared radiation, in both intensity and depth, fails to meet the practical needs for precise meridian conditioning. Second, the combined application of a single physical field and bioelectric modulation components is merely a simple functional superposition, lacking a scientific mechanism for the synergistic action of thermal, magnetic, and electric fields. Consequently, it struggles to effectively promote local blood circulation and enhance tissue metabolic efficiency.

[0004] In terms of achieving antibacterial and antioxidant functions, existing technologies face three prominent challenges: First, functional ingredients such as silver ions and VC are mostly attached to the fiber surface through direct loading or simple coating processes. This combination makes the functional ingredients extremely easy to lose during daily washing and wearing, resulting in poor wash resistance. Second, the sustained-release system of the functional ingredients lacks responsiveness to the human body environment and cannot achieve targeted release based on the physiological state of specific parts (such as pH value, temperature, etc.), affecting the accuracy of functional performance. Third, the biosafety issue of high-concentration silver ions has not been completely resolved, and they do not form an effective antioxidant synergistic effect with ingredients such as VC, posing a potential risk of causing skin irritation.

[0005] In summary, current functional underwear technology generally suffers from obvious defects such as functional fragmentation and insufficient long-term effectiveness: functional design is mostly limited to a single function or a limited combination of several functions, failing to build a multi-effect synergistic system for meridian conditioning. The material preparation process has also failed to break through the technical bottlenecks of washability and sustained-release stability, resulting in the rapid attenuation of core functions during actual wear and use. Therefore, how to achieve precise targeted conditioning of meridian acupoints, the systematic synergistic effect of multiple functional ingredients, and the long-term stability of functional release has become a key technical problem that needs to be overcome in this field of technology.

[0027] Example 1 This embodiment provides a method for preparing six-effect synergistic meridian conditioning multifunctional underwear, which is applicable to a five-zone functional material system to achieve accurate response to the flow of qi and blood in the human body. The following implementation contents are provided: Purpose of the experiment: Preparation of six-effect synergistic meridian conditioning multifunctional underwear.

[0028] Experimental materials: Nano-tourmaline-tourmaline composite fiber, Fe-Ga magnetostrictive fiber, silver ion-VC composite microcapsule, germanium-silver ion.

[0029] Experimental steps: S1: 0.1M AgNO3 solution and chitosan with a deacetylation degree of ≥90% were mixed in a ratio of 1:3, NaBH4 was added dropwise to reduce the mixture to prepare a core layer, and VC and sodium alginate were mixed in a ratio of 1:2 to coat the core layer by electrostatic adsorption; S2: subsequently homogenized at 120 MPa and ultrasonicated at 40 kHz for 10 min, with a particle size distribution of D90 ≤ 80 μm; S3: Finally, hot pressing is performed at 170°C and 4 MPa for 4 minutes to ensure that the silver ion-germanium composite layer is evenly embedded in the fiber to prepare the cup functional layer; S4: Nano-tourmaline-tourmaline composite fiber is used as the front functional layer, Fe-Ga magnetostrictive fiber sheet with a magnetic induction intensity of 0.004mT±5% is used as the groin functional layer, pH-responsive silver ion-VC composite microcapsules are used as the bottom functional layer, and focused magnetic flux lines with a magnetic induction intensity of 0.004mT±5% are used as the Guanyuan functional layer; S5: stacking the front functional layer, the groin functional layer, the crotch functional layer, the cup functional layer, and the Guanyuan functional layer to obtain the multifunctional underwear.

[0030] Experimental results: See Table 1 for details.

[0031] Table 1: Test results of Example 1 Antibacterial Antioxidant Metabolic regulation Meridian regulation Microcirculation improvement Example 1 ＞90% 80-90% 10-15% increase 10-20% decrease in resistance 10-20% increase in vascular density The six-effect time-space synergy cleverly realizes the efficient antibacterial effect of silver ions, the long-lasting antioxidant effect of VC, the precise metabolic regulation of germanium, and the dynamic synergy of magnetic therapy. Silver ions destroy the lipid bilayer structure of bacterial cell membranes through contact reaction, and at the same time bind to the DNA helix chain to inhibit its replication. The inactivation rate of common pathogens such as Escherichia coli and Staphylococcus aureus can reach 99.9%. Among them, the germanium element neutralizes free radicals by releasing negative oxygen ions. Its antioxidant capacity is 40% higher than that of traditional antioxidants. The composite fiber with a germanium content of 0.5% reached 89% in the DPPH free radical scavenging rate test. VC acts as a reducing agent to stabilize the valence state of silver ions, and at the same time enhances the anchoring effect of silver ions on the fiber surface through electrostatic adsorption to form a dynamic sustained-release system. The synergistic effect of the three improves the antibacterial durability to more than 95% activity after 100 washes. The underwear relies on temperature-sensitive phase change microcapsules and enzyme-responsive encapsulation technology to accurately realize the dynamic release of functional materials in time. Its various performance test data can be referred to Figure 1 . The experimental results clearly show that after wearing it continuously for 28 days, the waist circumference is significantly reduced by 4.8cm, and the antioxidant capacity is stabilized at 89%. This patent is based on the theory of Chinese medicine for chrono- ...

[0032] Comparative Example 1 This embodiment provides a method for preparing traditional meridian conditioning underwear, including the following implementation contents: Purpose of the experiment: Preparation of traditional meridian regulating underwear.

[0033] Experimental materials: Artemisia fiber, Angelica sinensis-Ligusticum chuanxiong compound extract, sericulture silk fabric, cotton and linen blended fabric, beeswax Experimental steps: S1: Dry and crush mugwort through an 80-mesh sieve, mix with mulberry silk fiber at a mass ratio of 1:5, card into a web, and then use a needle punching process to make mugwort functional surfaces as the front and back waist functional layers; S2: Melt the Angelica sinensis-Ligusticum chuanxiong composite extract and beeswax at a ratio of 2:1 at 65°C and evenly coat the surface of cotton and linen blended fabric. After cooling naturally, a film layer is formed as the Guanyuan acupoint functional tablet. S3: Select 12 momme mulberry silk fabric as the base fabric, cut the mugwort functional cotton into the front panel and the back waist functional layer, and suture the Angelica sinensis-Ligusticum chuanxiong medicinal slices to the corresponding position of Guanyuan acupoint; S4: The functional layers are joined to the silk base fabric using traditional flat-sewing technology, and the cuffs and hem are edged with cotton and linen to create traditional meridian conditioning underwear.

[0034] Experimental results: See Table 2 for details.

[0035] Table 2: Test results of Comparative Example 1 Antibacterial Antioxidant Metabolic regulation Meridian regulation Microcirculation improvement Comparative Example 1 62-68% 52-58% 5-8% increase 6-9% decrease in resistance 22-28% increase in vascular flow rate While the volatile oils in mugwort used in this method possess a naturally mild antibacterial effect, and the Angelica sinensis-Ligusticum chuanxiong complex extract can enhance this antibacterial effect, the lack of potent antimicrobial components like silver ions results in a relatively narrow antimicrobial range. While the brass compounds in mugwort and the ferulic acid in angelica possess some antioxidant activity, the active ingredient content is low and the release rate is slow, resulting in a moderate overall antioxidant capacity. The Chinese medicinal herbs used in this method can gently stimulate acupuncture points through transdermal absorption, thereby promoting the circulation of qi and blood. However, due to the lack of physical stimulation such as magnetic fields, the extent of metabolic regulation is relatively limited. Angelica sinensis's blood-activating and qi-invigorating properties can regulate qi and blood in the meridians through transdermal action at acupuncture points, but the onset of action is relatively slow and the intensity of the conditioning is relatively weak. While the volatile oils in mugwort can dilate capillaries and improve local microcirculation, the lack of infrared assistance from tourmaline limits the extent of blood flow acceleration and temperature elevation.

[0036] Comparative Example 2 A method for preparing traditional meridian conditioning underwear is provided, and the following implementation contents are provided: Experimental materials: Ginger-safflower compound extract, Eucommia ulmoides powder, ramie fiber cloth, pure cotton gauze, mulberry silk flakes Purpose of the experiment: A traditional meridian regulating underwear is prepared.

[0037] Experimental steps: S1: Heat the ginger-safflower composite extract to 80°C, soak the ramie fiber cloth in it for 30 minutes, simmer on low heat for 15 minutes, and then cool naturally. Repeat the immersion and boiling three times. After drying, prepare the shoulder and neck functional layer and the waist and kidney functional layer. S2: Pour Eucommia ulmoides powder into a pure cotton gauze bag and seal the bag with a beeswax-rosin mixture to make a sustained-release medicine capsule, which serves as the Dantian functional layer; S3: Using mulberry silk floss as the base fabric, the shoulder and neck functional layer and the waist and kidney functional layer are sewn to the corresponding acupuncture points. The dantian medicine bag is fixed in the center of the front panel with a detachable hidden pocket design. S4: The traditional button stitching technique is used to connect the functional layers, and the cuffs and hem are wrapped with pure cotton to make a meridian conditioning underwear with adjustable tightness.

[0038] Experimental results: See Table 3 for details Table 3: Comparative Example 2 test results Antibacterial Antioxidant Metabolic regulation Meridian regulation Microcirculation improvement Comparative Example 1 55-60% 48-53% 4-6% increase 5-8% decrease in resistance 18-25% increase in vascular flow rate Gingerol in ginger has some antibacterial activity, and the breathability of ramie fiber itself inhibits bacterial growth, but it contains no strong antibacterial ingredients and has a mild antibacterial effect. Safflower glycosides in safflower and chlorogenic acid in eucommia have antioxidant properties, retaining some activity after the soaking process, but their overall antioxidant capacity is weak. Ginger volatile oil promotes local metabolism. Eucommia ulmoides assists in regulation by tonifying the liver and kidneys, but lacks physical stimulation and thus has a small degree of metabolic regulation. Safflower's blood circulation and meridian dredging effects, combined with ginger's warming and cold-dispersing properties, act synergistically on acupuncture points, slowly regulating qi and blood in the meridians through transdermal absorption, resulting in a relatively mild conditioning effect. Safflower glycosides dilate capillaries, and ginger volatile oil enhances hemodynamics, but without the assistance of infrared or magnetic fields, the extent of improvement in microcirculation is limited.

[0039] Example 1 uses modern materials such as nano-tourmaline-tourmaline composite fiber and Fe-Ga magnetostrictive fiber, and constructs a five-zone functional material system through high-pressure homogenization, ultrasonic treatment and hot pressing processes to achieve six-effect space-time synergy. Its antibacterial rate exceeds 90%, antioxidant capacity reaches 80-90%, metabolic regulation is improved by 10-15%, meridian resistance is reduced by 10-20%, blood vessel density is increased by 10-20%, and waist circumference is reduced by 4.8cm after continuous wearing for 28 days, breaking through the single function limitation of traditional underwear. When the product line prepared in Example 1 is used in the fitness series, it focuses on sports antibacterial and metabolic acceleration, suitable for yoga clothes and running underwear. In the beauty series, the focus is on anti-aging and repair functions. The silver ions used in Example 1 are recyclable nanoparticles with a recovery rate of 85%, reducing the raw material cost by 30%.

[0040] Comparative Example 1 utilizes traditional natural medicinal materials such as mugwort fiber and a composite extract of angelica and Chuanxiong as its core ingredients. It is meticulously crafted using simple processes such as traditional acupuncture and melt coating. Its conditioning effects rely primarily on the slow transdermal absorption of its natural ingredients. Its antibacterial rate remains at 62-68%, its antioxidant effect is in the 52-58% range, its metabolic regulation capacity is only enhanced by 5-8%, its meridian electrical resistance is reduced by 6-9%, and its vascular flow rate is increased by 22-28%. While this underwear exhibits some basic conditioning effects, its lack of potent functional ingredients like silver ions and physical stimulation such as magnetic fields results in relatively weak functional strength and a limited range of effects.

[0041] Comparative Example 2 utilizes traditional medicinal herbs such as a natural ginger-safflower composite extract and Eucommia ulmoides powder, meticulously prepared through traditional medicinal dyeing and sachet filling techniques. It focuses on mild meridian warming and collateral dredging effects. Its antibacterial rate is 55-60%, its antioxidant capacity is in the 48-53% range, it improves metabolic regulation by 4-6%, reduces meridian resistance by 5-8%, and increases vascular flow rate by 18-25%. This underwear primarily relies on the natural activity of the medicinal herbs themselves, without the use of any additional synergistic techniques. As a result, its conditioning intensity is more moderate, and the duration of its effects is relatively short.

[0042] refer to Figure 1 Performance test data for this six-effect synergistic meridian conditioning multifunctional underwear is presented, visually demonstrating its functional retention under different usage conditions. As can be seen from the figure, while the underwear's core performance fluctuates somewhat with increasing wear or washing frequency, it remains generally stable. Specifically, after 25 uses or washes, relevant performance indicators such as antibacterial and antioxidant properties remain at high levels, with some reaching over 95%. After 50 uses or washes, performance slightly declines, but most indicators remain around 90%. Even after 75 and 100 uses, key functional indicators remain above 70%, demonstrating excellent washability and long-lasting effectiveness. Combined with experimental data, the figures in the figure echo the results of a 4.8cm waist circumference reduction and 89% antioxidant capacity after 28 days of continuous wear, confirming the effectiveness of the underwear's chronodynamic release of functional materials through thermosensitive phase-change microcapsules and enzyme-responsive encapsulation technology. Figure 1 It clearly demonstrates that it has broken through the bottleneck of traditional functional underwear that suffers from rapid functional attenuation due to technological limitations, highlights the advantages of the six-effect time-space synergy system in ensuring long-term functional effectiveness, and provides data support for the underwear to continue to play its antibacterial, antioxidant, metabolic regulation and other roles in actual wear.

[0043] This patent discloses a six-effect synergistic meridian conditioning multifunctional underwear and its preparation method, which includes components such as nano-tourmaline-tourmaline composite fiber and Fe-Ga magnetostrictive fiber. It is made by preparing silver ion-VC composite microcapsules and stacking multifunctional layers, achieving six synergistic effects of far-infrared therapy, negative ion release, magnetic therapy, antibacterial, antioxidant and bioelectric regulation. Various performance indicators are significantly better than those of comparative examples 1 and 2 using traditional medicinal materials and processes. It integrates modern material technology and dynamic release technology, not only enhancing basic functions, but also improving metabolic regulation and meridian conditioning effects through spatiotemporal synergy. It combines silver ions with germanium for the first time, introduces meridian flow regulation, and innovatively applies the silver ion-VC-germanium ternary synergistic system. It proposes combining magnetic therapy with acupoint stimulation to increase UCP1 protein expression by 41%, breaking through the limitations of traditional functional underwear.
