Abstract:
In order to improve the surface properties of cotton fabrics, using 2,3-epoxy-propyl dodecyl dimethyl ammonium chloride as cationic chitosan reagent and 3-glycidoxypropyltrimethoxysilane (GPTMS) as crosslinking agent, by sol-gel method, chitosan quaternary ammonium salt/silica hybrid film were constructed by in situ deposition on cotton fiber. SEM and EDS analysis results confirmed the quaternary ammonium salt/silica hybrid film was deposited on the surface of cotton fiber. After deposition modification, surface properties of modified cotton such as wettingablity, adsorption properties produced significant changes. With the deposition time increasing,the hydrophobic properties and anti-UV properties increased.
Key words: chitosan, quaternary ammonium salt, cotton, silica crosslinking, modification
