Abstract
Nonwoven fabric, film, and blocks of polyester were dipped into the various concentrations of methanol solution of γ-aminopropyltriethoxysilane for different times. The best wettability, according to the impregnating velocity and the contact angle of diglycidylether bisphenol A with the treated nonwoven fabric, film, and block, can be analyzed by the improved Langmuir adsorption rate equation, in which the diffusion rate for the γ-aminopropyltriethoxysilane molecule in the methanol solution is introduced. The maximum molecular number in the γ-aminopropyltriethoxysilane monolayer, deposited on the polyester surface, is equal to the molecular number theoretically calculated from the area occupied by the rotation of γ-aminopropyltriethoxysilane dimer around the axis of the interface linkage to the polyester. According to the analysis of impregnating rate through the polyester nonwoven fabric by using Gibbs's adsorption equation, the number of diglycidylether bisphenol A molecules adsorbed on the treated polyester fiber surface becomes 4 times larger than that on the polyester fiber surface without treatment.
