We report a rapid,
environment-friendly, and costeffective fi nishing method for cotton textiles
by using the isocyanate-coupled sulfopropylbetaine (NCO-sulfopropylbetaine) as
the AFA through covalent bond. The sulfopropylbetaine-fi nished cotton textile
performs the following functions: (i) resists initial bacterial
attachment; (ii) kills attached bacteria; and (iii) releases dead bacteria.
Moreover, the hydrophilicity, moisture/air permeability, and mechanical properties
of cotton textiles were improved after fi nishing.The antibacterial mechanism
of NCO-sulfopropylbetaine was also investigated by isobaric tags for relative
and absolute quantitation (iTRAQ) proteomics. Most intriguingly,
NCOsulfopropylbetaine shows nontoxicity and good biocompatibility in vivo.
