Problems solved by technology

[0004] In the process of adding titanium dioxide nanoparticles to the spinning solution for electrospinning to obtain antibacterial fibers, titanium dioxide nanoparticles are easy to form agglomerates and easily block the needle, making the antibacterial effect worse, and the durability of titanium dioxide nanoparticle-loaded fibers is the same. Poor, titanium dioxide nanoparticles are easy to fall off during washing and friction, which affects the antibacterial effect, and when adding titanium dioxide nanoparticles to the spinning solution to prepare antibacterial fibers, knots will be formed in the fibers, reducing the mechanical properties of the fibers

Abstract

The invention discloses an anti-bacterial nanofiber material and application thereof, and belongs to the technical field of nanofiber materials. The anti-bacterial nanofiber material is prepared by performing electrostatic spinning on a spinning solution containing modified titanium dioxide nanoparticles, wherein a preparation method for the modified titanium dioxide nanofiber material comprises the following steps of uniformly mixing polydatin and a titanium dioxide nanoparticle dispersion liquid; and adding water with stirring, and performing suction filtration, washing, ball milling with aball mill and calcining to obtain the modified titanium dioxide nanoparticles. According to the anti-bacterial nanofiber material prepared by from the modified titanium dioxide nanoparticles, PET andPA6, the anti-bacterial performance is at least up to 90 percent, and the antibacterial ratio is reduced by less than 1 percent after washing by 50 times.

Description

technical field [0001] The invention belongs to the technical field of nanofiber materials, and in particular relates to an antibacterial nanofiber material and uses thereof. Background technique [0002] Antibacterial fiber refers to a new type of functional fiber that can kill or inhibit microorganisms. It is now widely used in home textiles (including underwear, sweatshirts, old, pregnant and infant clothing, etc.) and medical textiles (surgical gowns, hospital gowns, bed sheets, etc.). , curtains, and bandages, etc.). Fabrics made of antibacterial fibers can resist the adhesion of bacteria on the fabric, reduce the number of bacteria on the fabric, ensure the safety of people-fabric-environment, and keep people away from germs. The earliest use of the concept of antibacterial by humans can be traced back to the Neolithic Age more than 10,000 years ago, when people began to use salt to preserve food for long-term storage, and salt became the earliest antiseptic and antib...
