Abstract
The present disclosure provides a compound and methods of preparing the compound. The compound has anti-microbial and anti-mite properties and can be bonded to materials such as fiber and synthetic polymer. The compound may also be used in a finishing agent for textiles, fibers, or yarns to protect these materials against microorganisms and mites. Additionally, when these materials are treated with a relatively low dosage of the compound, long-lasting and effective anti-mold and anti-mite effects may be achieved at a relatively low cost.
