Problems solved by technology

[0004] The technical problem to be solved by the present invention: due to the extremely high water solubility of the cationic quaternary ammonium salt, the antibacterial performance of the antibacterial fabric will drop sharply after being washed several times, resulting in unsatisfactory antibacterial durability. A preparation method of a durable fabric antibacterial finishing agent. The invention uses wool as a raw material, and after washing, undergoes alkali-soluble decolorization to make a wool keratin solution, and then uses sodium hydroxymethyl cellulose as a template agent to convert nano Silicon is made of nano-silica with a porous structure with good dispersion, and then the porous structure is used to absorb octadecyl ammonium chloride to make an antibacterial agent. Finally, the prepared wool keratin solution is used to compound the antibacterial agent and silicone oil to obtain a durable type Fabric Antibacterial Finishing Agent

Abstract

The invention relates to a preparation method of a durable fabric antibacterial finishing agent, belonging to the technical field of fabric finishing. In the present invention, wool is used as a raw material, and after being washed and decolorized by alkali solution, a wool keratin solution is prepared, and then sodium hydroxymethyl cellulose is used as a template agent to make nano silicon dioxide into a porous structure nanometer with good dispersibility. Silicon oxide, and then use the porous structure to absorb stearyl ammonium chloride to make an antibacterial agent, and finally use the prepared wool keratin solution to compound the antibacterial agent and silicone oil to obtain a durable fabric antibacterial finishing agent. The durable fabric antibacterial finishing agent prepared by the present invention prepares porous nano-silica, uses its large specific surface area to load quaternary ammonium salt antibacterial agents, and then uses wool keratin solution to coat the antibacterial agent and covers it on the surface of the fabric. , Form a protective film, significantly improve the antibacterial durability of the fabric.

Description

technical field [0001] The invention relates to a preparation method of a durable fabric antibacterial finishing agent, belonging to the technical field of fabric finishing. Background technique [0002] For a long time, the development of my country's textile industry has mainly relied on the production of low-value-added, traditional, and general-purpose fiber varieties. With the technological progress of the industry and the development of social needs, the market challenges and survival of traditional low-value-added textile products are facing The pressure is increasing day by day. Under the background of the country's industrial upgrading, the development of high-tech, healthy and green fiber fabrics has become an important part of the structural adjustment of the textile industry. Among them, the development of a new type of high-efficiency textile fiber antibacterial agent is of great significance for improving the economic added value of my country's textile product...
