Abstract
Polysaccharide fibres, such as cellulose or starch, modified by grafting an amino-containing antimicrobial polymer (ACP) onto the fibres or starch using a co-polymerization reaction, exhibits high antimicrobial activity. For example, the presence of 1.0% by weight grafted polymer in the cellulose fibres or starch fibres results in excellent antimicrobial activity (over 99% inhibition). The application further discloses that including triclosan or butylparaben into a novel cationic β-cyclodextrin polymer or nanocapsule yields a bacteriostat.
