Abstract: A glycidyl methacrylate(GMA)modified polyacrylate binder for pigment printing,which was synthesized by seeded semi-continuous emulsion polymerization,was applied to improve the handle and fastness of printed textile.The effects of dosage of binder,pH value and baking temperature and time on dry and wet rubbing fastness,color strength(expressed as(K/S) value) and the handle of pigment printed goods were studied and analyzed.And The results indicate that better printing effect can be obtained with this product when the dosage of this binder is about 10% of printing pastes,the range of pH value in 7-8,the baking at(150 ℃) for(3 min.) Compared with other homemade or imported similar products,the GMA modified acrylate binder can enhance more the color strength of printed goods and give softer handle.
