Abstract

The invention relates to a polyhexamethylene biguanide hydrochloride compound microencapsulated antibacterial finishing agent and a preparation method thereof. The antibacterial finishing agent comprises a core material and a shell material; the core material comprises polyhexamethylene biguanide hydrochloride, nanometer copper ions, 3-methyl-4-isopropylphenol, a dispersant, an emulsifying agent and a stabilizer; and the shell material is a mixed biological adhesive material composed of a synthesized biological adhesive material and chitosan. The antibacterial finishing agent has high efficiency, wide spectrum and washing resistance to various fabrics and is high in safety, simple in preparation process and low in cost.

Description

technical field [0001] The invention relates to the field of antibacterial finishing agents, in particular to a microcapsule antibacterial finishing agent compounded with polyhexabiguanide hydrochloride and a preparation method thereof. Background technique [0002] Antibacterial finishing agents can be mainly divided into three types: inorganic, organic and natural. The early antibacterial agents basically belonged to the organic series, and most of them were various complex compounds containing nitrogen, sulfur, chlorine and other elements. The main varieties were: quaternary ammonium salts, biguanides, alcohols, phenols, aldehydes, organometallics , pyridines, thiophenes, etc. This type of antibacterial agent has good short-term antibacterial effect, but most of them have the disadvantages of poor heat resistance stability and short service life. [0003] In the past ten years, the requirements for green environmental protection have become more and more stringent, and ...
