Chitosan-modified corn starch was prepared and then applied as a glass fiber sizing agent.?The effect of the chitosan on starch-based emulsion, film and sized glass fiber was studied.?When 5 % of the chitosan was added, the overall performance of the modified film-forming?agent was optimal. The viscosity, surface tension and zeta potential of the sizing agent were?44.99 mPa·s, 51.29 mN·m-1 and 4.5 mV, respectively. The modified sizing agent could easily?spread over the surface of glass fibre, and conglutinated to the glass surface firmly. The tensile?strength and stiffness of modified-starch glass fiber reached 0.43 N·tex-1 and 4.96 cm. Glass?fiber with good overall performance was obtained.
