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) and dissolve them in dichloromethane at room temperature to obtain a mixed spinning solution; wherein PLLA is in the mixed spinning solution 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 electrostatic spinning machine, and perform jet drawing under the action of a strong electric field to obtain an intermediate fiber material; the drawing speed is 2-5 m / s, the environmental temperature of the drawing process is 20-25 degrees Celsius, and the electric field The intensity is 10KV. In the electrospinning process, the electric field force overcomes the surface tension of the tiny droplets of the spinning solution to form a droplet form suitable for spinning. Dichloromethane evaporates quickly. PLLA, PC and Polyvinylcarbazole have poor compatibility ...

Embodiment II

[0045] Take 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: PVDF20g: DMF100mL, that is, add 10gPVP and 20gPVDF to every 100mL of DMF.

[0046] Put the spinning solution into the electrospinning machine and perform jet drawing under the action of a strong electric field to obtain an intermediate fiber material; the drawing speed is 2-5 m / s, and the environmental temperature of 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 the volatilization of the solvent and form an intermediate fiber material with a high density of holes. In the process of electrospinning, because PVP and PVDF are incompatible with each other, the two are separated and enriched. DMF as a solvent is fully...

Embodiment III

[0051] Take polyacrylonitrile (PAN) and polyethylene oxide (PEO) into dimethylformamide (DMF), and prepare a mixed solution at a constant temperature of 80 degrees Celsius; 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 both PAN and PEO in the mixed solution remains 8wt%; the mixed solution is used as a spinning solution.

[0052] Put the spinning solution into the electrospinning machine and perform jet drawing under the action of a strong electric field; the temperature can be kept at room temperature. During the drawing process, the electric field strength is 8KV and the fiber obtained after drawing is placed in a vacuum for 24 hours to allow the residual DMF solvent on the fiber Volatile; further, the fiber is immersed in a water bath of deionized water at 70 degrees Celsius for 10 minutes to remove the PEO in the fiber. Holes are formed...

Abstract

The invention relates to a fiber costume material with an antibacterial health function and a preparation technology of the fiber costume material. By preparation of hole functional fibers with high distribution density, most of nano silver metal particles can be distributed in holes in the surfaces of the fiber in an embedded manner, and only a small part of nano silver metal particles are attached to the surfaces of the fibers; therefore, in the long-time use process of the costume material, the nano silver metal particles are unlikely to fall off even if the costume material is repeatedly washed in water; furthermore, the oxidization action of silver is suppressed, and efficient and full use of noble metal raw materials is realized.

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 with 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 achieve the effects of preventing disease and infection, preventing mold and odor, and promoting health. They are especially suitable for clothing products that directly contact human skin and organs, such as underwear, footwear, and masks. [0003] Antibacterial and health-care functional clothing materials are added with antibacterial and antibacterial ingredients into ordinary clothing materials. These ingredients will be released continuo...
