| Summary: | The hydrophilicity of polyester fabric surfaces has
been modified using silica-chitosan nanocomposites. The silica-chitosan
nanocomposite was synthesized by the sol-gel method from sodium silicate and
various chitosan concentrations of 0 – 1.5% at a pH of 3 – 5. A single jersey
knitted polyester fabric was coated by silica-chitosan nanocomposite using the
pad-dry-cure method. It was found that the chitosan concentration and the
solution pH controlled the formation of various size distributions of sphere
nanocomposites with an average size of 96.0-201nm. The coated polyester fabric
with sphere silica-chitosan exhibits a rough surface and produces a contact
angle approaching 0°, facilitating the polyester fabric's speed-up water
absorption and hydrophilic properties. |
