Problems solved by technology

However, the functional components used in the above patents are silver-containing hydrogels, rather than silver metal particles with better effects; moreover, a considerable part of elemental silver is always enclosed in the hollow fiber and cannot be released, and the release efficiency is low, and the sterilization and inhibition The effect of bacteria is limited
[0007] It can be seen that in the prior art, there is still a lack of a functional component that uses nano-silver metal particles as a bactericidal and antibacterial agent, and realizes that the nano-silver metal particles are tightly combined with fibers and is not easy to detach, which is conducive to the efficient use and full release of silver particles, and can Antibacterial functional clothing material that prevents rapid oxidation of silver metal particles

Embodiment I

[0038] Take polylactic acid (PLLA), polycarbonate (PC) and polyvinylcarbazole (Polyvinylcarbazole), dissolve in methylene chloride at room temperature to obtain a mixed spinning solution; wherein, in the mixed spinning solution, PLLA The mass concentration of PC is 3-5wt%, the mass concentration of PC is 12-15wt%, and the concentration of polyvinylcarbazole is 6-8wt%;

[0039] Put the mixed spinning solution into an electrospinning machine, and perform jet drawing under the action of a strong electric field to obtain a fiber material intermediate; the drawing speed is 2-5 m / s, the ambient temperature of the drawing process is 20-25 degrees Celsius, and the electric field Strength 10KV. During the electrospinning process, the electric field force overcomes the surface tension of the tiny droplets of the spinning solution to form a droplet shape suitable for spinning, dichloromethane evaporates quickly, and PLLA, PC and Polyvinylcarbazole are poorly compatible with each other. ...

Embodiment II

[0045] Put polyvinylpyrrolidone (PVP) and polyvinylidene fluoride (PVDF) into dimethylformamide (DMF) to prepare a mixed solution as a spinning solution; the mass-volume ratios of the above three in the mixed solution are: PVP10g: PVDF 20g : DMF100mL, that is, add 10g of PVP and 20g of PVDF to every 100mL of DMF.

[0046] Put the spinning liquid into the electrospinning machine, and spray and draw under the action of a strong electric field to obtain the intermediate fiber material; the drawing speed is 2-5 m / s, the ambient temperature during the drawing process can be kept at room temperature, and the electric field strength is 15KV. After electrospinning and drawing, it is placed in a vacuum environment for drying to promote solvent volatilization and form a fiber material intermediate with high-density holes. During the electrospinning process, due to the mutual incompatibility of PVP and PVDF, the two phases are separated and enriched, and DMF as a solvent is fully volatil...

Embodiment III

[0051] Get polyacrylonitrile (PAN) and polyethylene oxide (PEO) and drop into dimethylformamide (DMF), prepare mixed solution under the constant temperature condition of 80 degrees centigrade; Wherein the mass concentration of PAN in the mixed solution is 4wt%-7wt %, preferably 6.8wt%; the mass concentration of PEO in the mixed solution is 1.2wt%-4.0wt%; the total mass concentration of PAN and PEO in the mixed solution remains 8wt%; the mixed solution is used as spinning solution.

[0052] Put the spinning solution into the electrospinning machine, and carry out jet drawing under the action of a strong electric field; the temperature can be kept at room temperature, and the fiber obtained after drawing with an electric field strength of 8KV during the drawing process is placed in vacuum for 24 hours, so that the remaining DMF solvent on the fiber Volatilize; then, immerse the fiber in deionized water at 70 degrees Celsius for 10 minutes to remove the PEO in the fiber. Cavities...

Abstract

The invention relates to a fiber clothing material with antibacterial and health-care functions and a preparation process thereof. The present invention prepares functional fibers with holes with a high distribution density, so that most of the nano-silver metal particles are embedded and distributed in the holes on the fiber surface, and only a small part of the nano-silver metal particles are attached to the fiber surface; In the long-term use of clothing materials, even if they are washed repeatedly, they are not easy to fall off, and the oxidation of silver is also inhibited, so that the efficient and full use of precious metal raw materials is achieved.

Description

technical field [0001] The invention relates to the field of textile and clothing materials, in particular to a fiber clothing material with antibacterial and health-care functions and a preparation process thereof. Background technique [0002] Functional clothing materials refer to clothing materials that have special functions such as health care, treatment, magnetism, luminescence, and heat generation on the basis of the general functions of ordinary clothing materials. Among them, antibacterial and health-care functional clothing materials can prevent disease infection, prevent mildew and deodorize, and promote health. They are especially suitable for clothing products such as underwear, footwear, and masks that directly contact human skin and organs. [0003] Antibacterial and health-care functional clothing materials are made by adding ingredients with bactericidal and antibacterial effects to ordinary clothing materials, and these ingredients will be continuously and...
