Definitions
- the purpose of the present invention is to provide a composite microsphere for antimicrobial use and a preparation method and application thereof.
- the present invention adopts the technical scheme as follows:
- the second oil phase is an oil-soluble liquid immiscible with water, preferably kerosene, paraffin oil, petroleum ether
- FIG. 2 is a photograph of a scanning electron microscope taken 7 days after the preparation of the composite microspheres according to the embodiment of the present invention (preserved in pure water).
- 5 is a scanning electron microscope image of fabric fibers after washing 30 times and 50 times in the embodiment of the present invention.
- the inorganic antibacterial drug is selected from the group consisting of silver or silver salt, and the ratio of silicon to aluminum.
- the cross-linked polysaccharide is selected from any one or a combination of at least two of the cross-linked natural linear polysaccharides and their derivatives and analogs; preferably the cross-linked natural linear polysaccharides are selected from the cross-linked chitosan, cross-linked sodium alginate, cross-linked gum arabic, cross-linked gelatin, cross-linked cellulose.
- the miscibility filtration method is to filter the natural plant extract; take the filtrate, add the stabilizer after standing, filter the filtrate after standing again, and then get the natural antimicrobial agent after standing again.
- This example evaluates the washability of the antimicrobial composite microspheres prepared in the present invention. That is, the composite microspheres are attached to the surface of the fabric by post-finishing, and after different times of washing, the retained amount of the composite microspheres is determined, and the durability of its antimicrobial function is evaluated.
