Grafting onto cotton fiber with acrylamidomethylated beta-cyclodextrin andits application

To chemically attach beta-cyclodextrin (CD) molecules to cotton cellulose, N-methylol-acrylamide (NMA) was used to synthesize a CD containing monomer, which was then grafted onto cellulose fibers. Initiation of the cotton cel lulose backbone with ceric ion before the addition of acrylamidomethyl cycl odextrin (CD-NMA) monomer was shown to be beneficial for grafting onto cott on cellulose by studying the reactions of eerie ion with CD, CD-NMA, or cot ton cellulose. The amount of chemically attached CD was determined by fluor escence measurements and compared with graft yields. The possibility of tex tile finishing of CD containing cotton fibers was investigated using benzoi c acid as an antibacterial finishing agent or vanillin as an aroma finishin g agent. Antibacterial activity of benzoic acid-treated samples were retain ed even after 10 laundering cycles and the vanillin fragrance lasted much l onger compared with the control sample, suggesting that utilization of CD i n functional textile finishing is indeed possible.
