Abstract:
In order to realize the in situ directed assembling of silver nanoparticles on cotton fabric and the green, convenient, efficient, and recyclable processing technology of antibacterial textile with silver nanoparticles, modified cotton fabric with the capabilities of capture and reduce silver ions, control the size of nanoparticles, and fixing them on the fabric was prepared by oxidizing cotton fabrics and then grafting modified polyamide hyperbranched polymer with a core-shell structure on them. The modified active cotton fabrics were utilized to in-situ assemble silver nanoparticles. The treated cotton fabrics were characterized. The antibacterial activity and washing durability of them were measured. The results active cotton fabrics were utilized to in-situ assemble silver nanoparticles. The treated cotton fabric were characterized. The antibacterial activity and washing durability of them were measured. The results indicate that the modified active cotton fabrics are prepared successfully by the above method and the modification treatment does not affcet the mechanical pwoperties of the fabrics obviously. The treatment of assembling silver nanoparticles on active cotton fabric can be peocessed continuously and realized zero release. Silver nanoparticles with the size of 5 to 25 nm are dispersed on the treated cotton fibers. The silver nanoparticles assembled cotton fabrics have excellent antibacterial activities and laundering durability. The bacterial reduction rates against Staphylococcus aureus and Escherichia coli both reach above 99.9%.
Key words: hyperbranched polymer, cotton fabric, silver nanoparticle, in situ, antibacterial finishing
