The antibacterial agent is chitosan and/or modified chitosan nanoparticles.
The chitosan is a natural glucosamine-based cationic polymer and has the characteristics of good biocompatibility, biodegradability, nontoxicity and the like; and the chitosan nanoparticles have larger surface area, Zeta potential and excellent activity, so compared with chitosan, the chitosan nanoparticles have more excellent functions of static resistance, antibiosis, crease resistance and the like.
Preferably, the antibacterial agent is modified chitosan nanoparticles.

The antibiotic is one or more than two of tetracycline hydrochloride, gentamicin sulfate and ciprofloxacin.
Preferably, the antibiotic is a mixture of gentamicin sulfate and ciprofloxacin, wherein the mass ratio of gentamicin sulfate to ciprofloxacin is (1-3): (1-2).
According to the invention, chitosan nanoparticles are prepared by using chitosan with positive charges and polyanions with negative charges through a physical cross-linking ionic gel method, so that the use of toxic materials is avoided, the side effect is reduced, and the biocompatibility is improved. The chitosan nanoparticles have the same functional groups as chitosan, and have a high surface area due to the nanostructure thereof, so that a large amount of amino groups are present on the surface of the chitosan nanoparticles. In the invention, the chitosan nanoparticles are used as carriers, and antibiotics with negative charges are adsorbed on the chitosan nanoparticles with positive charges of amino hydrogen through intermolecular hydrogen bonds, so that the antibiotics are introduced into a chitosan structure to form a semi-reticular structure, and the chitosan structure has super-strong antibacterial activity.

1. the invention provides a preparation method of super-washable coral fleece fabric, which uses a tree-shaped macromolecular polymer to treat gray fabric in pre-finishing, and has the advantages of simple process, environmental protection and high production efficiency, and greatly reduces the loss of structure and strength of fabric fibers, and improves the washing fastness of the coral fleece fabric. In addition, due to the introduction of silver ions, the antibacterial performance of the fabric is improved.
2. The dendritic polyamidoamine is adopted for pretreatment, and aminolysis can be caused to a polyester chain by the amino group existing at the tail end of a branched chain of the dendritic polyamidoamine, so that a large amount of amine and hydroxyl functional groups are formed on the fabric; the self-made antibacterial agent used by the invention takes chitosan with positive charge amino hydrogen as a carrier, so that the antibacterial agent can be firmly fixed with the fabric through electrostatic action, and the washing resistance is further improved.
3.
