Technical Field

[0001] The invention belongs to the technical field of biomedical materials, and particularly relates to a textile for relieving varicose veins and a preparation method thereof. Background Art

[0002] Varicose veins are a common vascular disease that can lead to poor blood circulation and other health problems. Traditional treatments for varicose veins include surgery and medication, but these have several drawbacks and limitations, such as the high surgical trauma, long recovery time, and limited effectiveness of medication.

[0003] Patent application number 201410175772.9 discloses health products for restoring cell vitality, as well as their preparation and use. The preparation method involves first selecting metals and alloys with health benefits, then shaping the metal into various metal products that facilitate effective contact with the affected skin and associated acupuncture points. These include directly applied acupuncture point patches, acupuncture point clips, health necklaces, and health bracelets. More common methods involve combining metal with fabric to create metal-containing textiles. One method involves directly sewing or gluing metal wire, metal sheets, gaskets, or metal chains onto fabric; another method involves blending metal fibers with conventional fibers; and finally, metal powder is sprayed onto fabric or mixed with resin, chitin, or glue and then adhered to fabric. The health products proposed in this invention have demonstrated excellent therapeutic effects and health benefits for conditions such as cervical spondylosis, lumbar spondylosis, periarthritis of the shoulder, knee and ankle joint swelling and pain, varicose veins, hypertension, hyperglycemia, insomnia, night sweats, and prostatitis. However, their effectiveness in alleviating varicose veins is limited.

[0004] Therefore, providing a textile or method that can effectively improve varicose veins is an urgent problem to be solved. Summary of the Invention

[0011] In step 1, Preferably, the mixing treatment comprises: heating to 220-240° C. and treating the bio-based fiber with an acidic or alkaline substance for 20-40 minutes.

[0012] Preferably, the melt spinning conditions are: a spinning temperature of 270 to 290° C., and a spinning pressure of 0.5 to 3 kPa.

[0013] In step 2, Preferably, the temperature is raised to 120-130° C., and the textile preform is dyed for 40-50 minutes.

[0014] Preferably, the heat setting conditions are: temperature of 160-190° C., heat setting speed of 15-30 m / min, and pressure of 0.5-3 kPa.

[0015] The beneficial effects of the present invention are: (1) The textile for relieving varicose veins of the present invention is made of bio-based fibers and nanomaterials. The bio-based fibers are selected from textile materials with good permeability and biocompatibility. By adding nanomaterials, textiles with AATH biological effects can be produced.

[0016] The textile for relieving varicose veins described in the present invention utilizes the AATH biological effect to activate the activity of biological molecules, thereby improving blood circulation, promoting metabolism and enhancing immune function from the inside. The good permeability and biocompatibility of the textile enable the textile to better contact the human body. The textile can absorb photoelectron energy and convert it into and release human-friendly wide-wavelength energy, which reaches deep into the body, expands blood vessels, improves blood flow, thereby improving microcirculation, enhancing metabolism and enhancing immune function. The thermal energy causes vasodilation, activates the activity of biological macromolecules, regulates the body fluid mechanism, and can effectively dredge and improve blood vessels to relieve varicose veins, achieving better therapeutic effects.

[0018] (2) The preparation method of the textiles described in the present invention first performs surface treatment on the bio-based fibers to enhance the hydrophilicity and adsorption properties of the fiber surface; then the fibers are mixed with nanomaterials and melt-spun. By optimizing the raw material ratio and melt-spinning process, the present invention enables the nanomaterials to be uniformly polymerized and dispersed inside the bio-based fiber slices. Through melt spinning, a stable AATH biological effect is formed on the surface of the textile, so that the textile has both good AATH biological effect and comfort; finally, through heat curing treatment, the stability and activity of the AATH biological effect substances in the textiles can be maintained and improved.

[0019] The preparation method of the present invention can form a durable and stable AATH biological effect protective layer on the surface of textiles, and this can be achieved by forming a nanoparticle layer of AATH biological effect inside and on the surface of the fiber.

[0020] (3) The preparation method of the textile of the present invention is simple, low-cost, and has a wide range of applications and is suitable for large-scale production. DETAILED DESCRIPTION

[0021] The present invention will be described in detail below, and the characteristics and advantages of the present invention will become clearer and more distinct with the following description.

[0022] A first aspect of the present invention is to provide a textile for relieving varicose veins. The textile for relieving varicose veins is made of 95 to 99.5 parts by weight of bio-based fibers and 0.5 to 5 parts by weight of nanomaterials.

[0023] Preferably, the textile for relieving varicose veins is made of 97.5 parts by weight of bio-based fibers and 2.5 parts by weight of nanomaterials.

[0024] The bio-based fiber is selected from one or more of chitin fiber, bamboo fiber, cuprammonium fiber, cellulose fiber-Tencel Lyocell, and bio-based nylon 56 fiber. Lyocell and bio-based nylon 56 fiber are cellulose fibers with good air permeability and comfort.

[0025] Preferably, the bio-based fiber is bio-based nylon 56 fiber. Bio-based nylon 56 fiber is a textile material with good permeability and biocompatibility.

[0026] The nanomaterial is selected from one or more of noble metal nanomaterials and nano-rare earth materials.

[0027] Preferably, the nanomaterial is a noble metal nanomaterial.

[0028] More preferably, the nanomaterial is gold, ruthenium, rhodium, palladium, platinum or platinum-gold.

[0029] The present invention can prepare textiles with AATH biological effects by adding nanomaterials to bio-based fibers with good permeability and biocompatibility. AATH is a new generation of anti-thrombotic fibers that use a photluminescence structure. Photluminescence: is the phenomenon of a substance re-emitting light after absorbing photons (photons). It absorbs the energy transmitted by photons (photons), such as sunlight and human body heat, and converts and re-radiates energy. The converted energy is released in a wide wavelength that is friendly to the human body. The far-infrared rays absorbed by the AATH fiber are radiated to the human body, and the warming effect can expand blood vessels, thereby improving blood flow. AATH photon energy can reach deep into the body, avoiding the disadvantage that far-infrared can only reach shallow levels. It can penetrate into the human body, generate heat from the inside, enhance blood circulation, promote metabolism, and improve immune function and other biological effects. This textile is called the "light of life."

[0030] The second aspect of the present invention is to provide a method for preparing the textile for relieving varicose veins according to the first aspect of the present invention, the method comprising the following steps: Step 1: mixing the bio-based fiber raw material, mixing and slicing the mixed bio-based fiber raw material and the nanomaterial, and then melt-spinning and weaving the mixed bio-based fiber raw material to obtain a textile preform; Step 2: dyeing, soaping, drying, and finally heat-setting the textile preform to obtain the textile for relieving varicose veins.

[0037] Mixing treatment of bio-based fibers can improve their permeability and adsorption capacity to enhance the hydrophilicity and adsorption properties of the fiber surface.

[0038] The weaving methods include warp knitting, weft knitting, tatting and the like.

[0039] In step 2, the temperature is raised to 120-130° C., the textile preform is dyed for 40-50 minutes, and then soaped, drained, and de-dried.

[0040] Preferably, the temperature is raised to 125° C., the textile preform is dyed for 45 minutes, and then soaped, drained, and dried.
