摘要

Modification of woolen fabrics were achieved by grafting β-cyclodextrin and β-chloro triazinylcyclodextrin in the presence of citric acid (CA) as cross-linking agent and phosphorous salts such as sodium hypophosphite (SHP) and sodium dihydrogen phosphate (SDP) using the pad dry cure technique. CA is expected to react with the β-CD (or wool) hydroxyl groups and wool terminal amino groups, to form ester cross-linkages or ionic bonds. The improved properties of wool fabrics were evaluated using urea bisulfite solubility test, tensile strength, elongation and crease recovery angle. Also, yellowness index and scanning electron microscopy were performed. Woolen fabrics treated with CA alone and CA/ CD shows antimicrobial properties.
