Abstract:

This paper stated the preparation of nano-modified polyacrylic acid sizing agents by adding self-made hybridized nano-TiO2(titanium dioxide)/PSt(Polystyrene) and nano-SiO2(silica dioxide)/PSt emulsion respectively into self-made polyacrylic acid sizing agents which called SW. Influences of two kinds of nano hybrid particles in nano-modified SW with different dosages on the strength of sizing yarns and mechanisms of increasing adhesion were analyzed. Experimental results showed that: 1. when two kinds of nano particles’ weight was about 1.1% of SW solid content, adhesion force of nano-modified sizing agents with Terylene/Cotton(T/C)fibers will reach the maximum,while when the weight of nano particles were less than 1.1% or more than 1.1%, the adhesion force between sizes and (T/C)fibers increased obviously or declined evidently; 2. scanning electronic microscope(SEM) photograph of roving chips displayed that fibers’ surface were completely covered by smooth size film and many hybrid nanoparticles between macromolecules of sizes, thus engendering huge bonding force between sizes and fibers, and increasing the slip resistance between fibers.
