ABSTRACT:
An aqueous starch-oil sizing composition is provided which produces improved processibility in woven and non-woven applications. The sizing has low viscosity starch, a lubricant which is a mixture of oil and wax where the wax is present in an amount of at least twice the oil, cationic lubricants, and a humectant. The size also includes an organo-functional silane coupling agent such as gamma-glycidoxypropyltrimethoxy silane which may be hydrolyzed. Emulsifiers, defoamers, and biocides may be present. Strands of glass fiber which have been treated with this size have generally shown a reduced tendency to shed the size from the strands, a reduction in the buildup of broken filaments or "fuzz" on processing equipment and reduced strand breakage.
