Title:
ANTIBACTERIAL FINISHING AGENT AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/045572
Kind Code:
A1
Abstract:
The present invention relates to the technical field of antibacterial agent preparation, and in particular to an antibacterial finishing agent and a preparation method therefor and a use thereof. The antibacterial finishing agent is prepared by dissolving a polymeric guanidine antibacterial agent, a cyanate monomer, imidazolidinyl urea, a dispersing agent, and an acid in deionized water, carrying out ultrasonic dispersion for 1 h to obtain a dispersion liquid, heating the dispersion liquid in a water bath to 30-80°C, reacting for 5-24 h, cooling to room temperature, and then performing filtering. The antibacterial finishing agent can be simply synthesized, has a water-soluble characteristic, and can be well combined with fabric, such that antibacterial fabric prepared from the antibacterial finishing agent has broad-spectrum, efficient, and lasting antibacterial performance, and is more washable and free of cleaning limitation of anionic detergents compared with some existing commercially available antibacterial fabric products.
