摘要

Functions of the polyamines in neutral rosin sizing were investigated using X-ray photoelectron spectroscopy(XPS) and laser diffraction particle analysis. The polyamine with a higher charge density and a smaller unite size could retainmore rosin and cover larger fiber surfaces. The XPS spectra demonstrated that polyallylamine.(PAAm) and polyvinylamine(PVAm) could react with a rosin size to form a -OC-N-CO- structure

but polydimethylamino ethyl methacrylate(PDMAEMA) could not. The formation of this structure may be a key step for effective sizing.
