Preparation of A Novel Anti-bacterial Wool Fabrics
β-cyclodextrin (β-CD) was modified by sulfonated reaction. The sulfonated-β-CD was grafted onto wool fabrics. A novel kind of anti-bacterial fabrics was prepared by filling the anti-bacterial agent (miconazole nitrate) into β-CDs caves fixed onto the fabrics. The optimum grafting conditions for sulfonated-β-CD onto wool fabrics were: sulfonated-β-CD 60 g/L,Na2SO4 5 g/L,pH=2~ 3,dipping the fabrics into solution at 90-100 0C for 50~60 min. Compared with the unmodified fabrics,the fabrics modified with sulfonated-β-CD increased the uptake of antibacterial agent,enhancing the antibacterial properties of the modified fabrics. The binding of β-CD onto the wool fabrics improved the resistance of the entrapped antibacterial agents to washing cycles,prolonging the antibacterial effect. The antibacterial abilities of the unmodified fabrics was almost lost when washing 5 times,while the modified fabrics with sulfonated-β-CD kept 60％~ 70％ even after washing 10 times.
