Carpets made with different blending ration of bamboo and cotton fibers were treated with modified chitosan by padding process. The best performance of the carpets treated was obtained when the carpets were padding with 70 g /L modified chitosan solution under the roller pressure of 0.14 MPa, and cured at 160 degrees C for 90 min. The antibacterial effect of the carpets treated with modified chitosan was characterized by the inhibition ratio to staphylococcus aureus, escherichia coli and Candida albicans and the lustrating ratio of mite. The treated carpets all showed broad-spectrum antimicrobial activity against gram-positive and gram-negative bacteria and fungi tested and modified chitosan is effective on anti mite.
