Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of moxa quilt, and particularly relates to a moxa health air-conditioning quilt. BACKGROUND

[0002] With the acceleration of social aging and the continuous expansion of sub-health population, the traditional medical model is gradually changing to the concept of "prevention first, combination of prevention and treatment" of big health. According to the data of the World Health Organization, more than 75% of the global population has different degrees of sleep disorders and chronic strain problems, and the health preservation concept of "warming meridians, dredging collaterals, supporting yang and consolidating the root" shows unique value in improving such health problems.

[0003] Artemisia argyi, as an important component of traditional Chinese medicine, its leaves are rich in eucalyptol, camphor, alpha-terpinene alcohol and other active ingredients, and have significant antibacterial and anti-inflammatory, dampness and cold dispelling, and promoting microcirculation effects. Moxa, as a product processed from the leaves of Artemisia argyi, also has the above properties and the effects of warming the meridians, dispelling cold, relieving pain, and regulating blood. The application of moxa natural health care properties and sleep is the research focus of the application.

[0004] Then, the inherent brittleness of moxa fibers leads to insufficient elongation at break, restricting the spinnability and product durability; the active substances in moxa are prone to loss due to volatilization, and the health care effect is not long-lasting; the natural antibacterial ingredients in moxa are prone to cause itching and hardening of the fabric due to the large fiber rigidity and poor spinnability, and it is difficult to meet the long-term close-to-body use demand, and the ordinary air-conditioning quilt has a low moisture absorption rate, which cannot match the sweat fluctuation in the human sleep cycle, and is prone to increase the hot and humid feeling and the turning frequency. Therefore, how to improve the long-acting antibacterial, body comfort and health intervention functions of the moxa quilt is the research focus of the application. SUMMARY

[0005] The application discloses a moxa health air-conditioning quilt to solve the above and any potential problems in the prior art. In order to solve the above technical problems, the specific preparation process is as follows:

[0006] The moxa, spandex and polyamide are blended and spun to obtain blended yarn as weft yarn, Xinjiang long-staple cotton yarn is used as warp yarn for weft knitting, and the knitted fabric is used as the close-to-body outer layer, and the basis weight of the fabric is 140±5 g / m²; the moxa and the polyamide are mixed in equal quality, and are laid into uniform flake by using an air-laid machine, and are used as the filling layer, and the basis weight is 150-160 g / m², and finally needle punching is used for reinforcement, the needle punching density is 120-150 punctures / cm², and hot air 130℃ is used for reinforcement for 30s to obtain the moxa health air-conditioning quilt.

[0007] The blending spinning includes: after 20-25 parts of the moxa is dry mixed with 0.8% lubricant powder in a mixer for 5 minutes, 8-15 parts of spandex master batch and 10-20 parts of nylon are added, the temperature in the mixer is 140-155 DEG C, 180-220 rpm is premixed and stirred for 15 minutes, spinning forming: screw rotation speed: 120 rpm, conventional melt spinning, spinneret aperture 0.15 mm, hole number: 72 holes, draft ratio 1:3.5, finally treated with water vapor, 100 DEG C for 3 minutes for setting;

[0008] The lubricant is rice chaff wax.

[0009] The moxa further includes modification treatment: five-year-old moxa is selected as raw material, composite biological enzyme hydrolysis technology is adopted, solid-liquid ratio is 1:12, liquid is acetic acid solution with pH 5.0, and 0.5% cellulase, 0.3% pectinase and 0.2% xylanase are added, pH is adjusted to 5.0±0.2 by adding acid salt, 45 DEG C, 150 rpm shock reaction is carried out for 2 hours, then 80 DEG C water bath is carried out for 10 minutes for inactivation, 40 DEG C deionized water is used for rinsing twice, vacuum filtration is carried out at-0.08 MPa until the moisture content is less than or equal to 35%, the moxa is immersed in 4-8% modified solution, the solid-liquid ratio is 1:8, 60 DEG C reaction is carried out for 40 minutes, 80 rpm, then the modified moxa is immersed in 4-8% softener solution, the ratio of the dry weight of the moxa to the weight of the solution is 1:10-15, the temperature is 40-50 DEG C, the time is 20-30 minutes, then 2000 rpm is used for spinning for 10 minutes, the moxa is laid on the environment of 60-85 DEG C for hot air drying for 10 minutes to obtain flexible moxa.

[0010] The modified solution is casein glue solution.

[0011] The softener is distearyl oxy ethyl hydroxy ethyl methyl ammonium methyl sulfate.

[0012] The advantages and beneficial effects of the application are:

[0013] 1. The application fuses the high active components of five-year-old moxa and complex enzymatic hydrolysis technology, significantly improving the release efficiency of antibacterial substances, and through body temperature stimulation to simulate the effect of traditional Chinese medicine moxibustion, achieving deep cold and dampness; The nano honeycomb pore structure formed by enzymatic modification gives the fiber excellent moisture absorption and quick drying performance; Casein glue constructs a three-dimensional protein network on the surface of moxa, greatly enhances the flexibility and compatibility with spandex and nylon, synchronously releases skin-friendly amino acids to neutralize metabolic acidic substances, optimizes the sleep microenvironment combined with distearyl oxy ethyl hydroxyethyl methyl ammonium methyl sulfate for softening treatment; Rice chaff wax, through surface lubrication and γ-oryzanol synergy, not only ensures smooth spinning and uniform distribution of functional components, but also forms a "membrane rupture-kill" dual antibacterial mechanism with moxa active ingredients, and realizes long-acting controlled release through casein glue film, combined with repellent substances to build an anti-mite and anti-allergic barrier, ultimately obtaining a moxa air conditioner quilt that can warm the meridians, dynamically dehumidify, long-acting antibacterial and comfortable.

[0014] 2. The enzymatic moxa and blending spinning process form nano-sized honeycomb pores, which give the fiber the ability to quickly adsorb body sweat and rapidly direct it to the outside of the fiber for evaporation through capillary action and vapor diffusion, preventing moisture from remaining between the skin and the quilt.

[0015] 3. The casein glue crosslinks into a three-dimensional network protein film on the surface of moxa, binds with moxa cellulose through hydrogen bonds, and makes moxa have a certain elasticity, which can improve the processing fluidity and component compatibility of the subsequent blend, and help spandex, nylon and other fibers better exert their elasticity and strength advantages, making the mechanical properties of the overall fiber more optimal and stable, enhancing its spinnability, and ultimately achieving better mechanical properties on the fiber.

[0016] 4. However, after the casein glue treatment enhances the spinnability of the fiber, its softness performance has decreased accordingly, so distearyl oxy ethyl hydroxyethyl methyl ammonium methyl sulfate is added to enhance its softness. Distearyl oxy ethyl hydroxyethyl methyl ammonium methyl sulfate is a high-efficiency and commonly used cationic quaternary ammonium salt. The long-chain alkyl group in its molecular structure can be adsorbed on the surface of the moxa fiber, forming a soft molecular film that effectively reduces the frictional resistance between fibers, directly compensating for the increased fiber rigidity that may be caused by the crosslinking network of casein glue, giving moxa excellent loftiness. This makes the final flexible moxa not only have the strength and spinnability given by casein glue, but also have the soft and comfortable feeling required for close-to-skin products, which is a key attribute for making high-end close-to-skin textiles. This treatment makes the subsequent high-shear intensive mixing and melt spinning with synthetic fiber masterbatch such as spandex and nylon have better processing fluidity, less fiber damage, and higher uniformity of each component, resulting in softer and more breathable textiles with better moisture absorption.

[0017] 5. Rice chaff wax powder is evenly wrapped on the surface of the flexible raw silk during the dry mixing stage, playing a lubricating role, reducing fiber friction and entanglement during the subsequent high-shear intensive mixing process with nylon and spandex masterbatch, and improving the uniformity of dispersion of each component. The lubricity helps to reduce the melt viscosity, making the subsequent melt spinning process smoother, reducing broken filaments, and improving spinning stability and efficiency. As a carrier of functional components, the uniform dispersion of rice chaff wax ensures the effective distribution of antibacterial and other functions in the final fiber. A small amount of wax can slightly plasticize the blended system, helping to further improve the flexibility and processing performance of the fiber.

[0018] 6. The mechanism of action of γ-oryzanol of rice chaff wax and active ingredients of raw silk is complementary, forming a strong and lasting double antibacterial and antiviral barrier. It not only has good antibacterial effect on Escherichia coli, Candida albicans and Staphylococcus aureus, etc., but also has good antiviral activity rate on influenza virus.

[0019] 7. The three-dimensional protein film formed by casein glue not only wraps raw silk, but also effectively fixes rice chaff wax particles on the surface or near-surface area of the blended fiber. This layer of protein film itself also has a certain barrier effect. When contacting microorganisms, the surface layer of the protein film may first act, at the same time, allowing γ-oryzanol and active ingredients of raw silk to be continuously and controllably released, achieving longer and more stable double antibacterial effect, and avoiding rapid loss of effective ingredients. The volatile repellent substances of raw silk and the active ingredients in rice chaff wax work together to form an unsuitable chemical environment for pests to breed inside and on the surface of the fiber, effectively preventing mosquitoes and mites, and having good antibacterial effect, which can improve the hygiene and durability of the product, especially suitable for people prone to allergies.
