| Abstract: | The advantages of using starch graft copolymers as warp sizes in textile were briefly discussed, and the factors of affecting adhesive capacity to the fiber were analysed. By using eerie ammonium nitrate as an initiator under nitrogen atomosphere, a number of vinyl and / or acrylic monomers such as acrylic acid, acrylamide, methyl acrylate, ethyl acrylate, butyl acrylate, hydroxyethyl acrylatc, methyl methacrylate, butyl methacrylate, vinyl acetate and the combinations among them were graft copolymcrized respectively onto granular corn starch in aqueous dispersion. The adhesive capacity of these starch graft copolymers to polyester / cotton fibers was evaluated by a slightly sized rovings according to V. K. Aggarwal's method which measures the breaking strength and elongation of the rovings impregnated with the size paste. The influences of the monomers and their combinations, the grafting technological processes and the pretrcatment methods before graft copolymerization upon adhesive capacity have been discussed in this paper. The results show that the factors above all have a marked influence upon the adhesive capacity of starch graft copolymers to polyester / cotton fibers. |
