A kind of preparation method of antibacterial auxiliary material

Abstract

The invention discloses a method for preparing antibacterial auxiliary materials, which improves the hydrophilicity of fiber webs through plasma treatment, so that antibacterial agents are more easily absorbed by the fiber webs. The treatment of the fiber web through the electric field can make the fiber monomers on the fiber web stand upright, which is more conducive to the penetration and embedding of the antibacterial agent; the direction of the magnetic field lines in the magnetic field can be parallel to or perpendicular to the running direction of the fiber web, and the fiber web After passing through the magnetic field, the nano-magnetic particles applied in the fiber web will be oriented under the action of an external magnetic field, making the orientation of the magnetic particles more regular, and the regularly oriented magnetic particles will make the auxiliary material have a magnetic field effect in a certain direction, which can improve the auxiliary material. blood microcirculation in the clothing site, and promote wound healing and tissue regeneration.

Description

technical field

[0001] The invention relates to a method for preparing a medical material, in particular to a method for preparing an antibacterial auxiliary material. Background technique

[0002] Plasma is an ionized gas that is the fourth state of matter different from solid, liquid, and gas. 99% of matter in the universe exists in the form of plasma. Macroscopically, plasmas are electrically neutral, however, plasmas contain free charges and are electrically conductive. Plasma technology is an emerging technology with amazing potential application value. In the medical field, plasma treatment technology can be used in wound healing, tumor treatment, tissue engineering, equipment disinfection and surgical equipment. In the field of textiles, plasma can graft new functional groups on the surface of textile substrates and use some active gases (such as oxygen, nitrogen, ammonia or water vapor) to improve the surface properties of polymers. In the electronics industry, p...
