Abstract

The invention discloses a method for preparing an inorganic aromatic nano-antibacterial agent and antibacterial fabrics. The method for preparing the inorganic aromatic nano-antibacterial agent comprises the following steps: swelling Carbomer resins with surfactants in deionized water, adjusting the PH value to 6.0-7.0 with triethanolamine and forming a stable colloid emulsion; and adding reducing polymers and a silver salt to the colloid emulsion and adding small molecular reducing agents for reduction at 5-100 DEG C in order to improve the purity of silver, thus obtaining the nano silver antibacterial agent. The antibacterial agent is used for padding or soaking the fabrics and the prepared antibacterial fabrics have the characteristics of fast antibacterium, high efficiency, broad spectrum and durability. The preparation methods and the finishing process have the advantages of simpleness, low cost, no pollution and easiness in industrialization.

Description

technical field [0001] The invention relates to an inorganic aromatic nano-antibacterial agent and a preparation method thereof, belonging to the field of nano-materials and technologies. Background technique [0002] Antibacterial fabrics have the advantages of blocking the spread of diseases, keeping clean and hygienic, maintaining the performance of fabrics themselves, including preventing fabric products from coloring, embrittlement and discoloration, etc., and have broad application prospects. The key to obtaining fabrics with excellent antibacterial properties lies in the selection of excellent antibacterial agents. The types of antibacterial agents have developed from the initial natural antibacterial agents to organic compound antibacterial agents, then to polymer antibacterial agents, and then to inorganic nanoscale antibacterial agents. Natural antibacterial agents mainly come from natural extracts, and the antibacterial effect is not obvious; organic antibacteria...
