Abstract
Sizing compositions for coating glass fibers as well as the coated fibers in which the compositions are constituted essentially of two film forming agents and of two lubricants. One film forming agent is a modified starch in which almost the entire mass of starch granules is burst. The second is an acrylic polymer, preferably a water-soluble one. One lubricant is non-ionic and preferably a mineral oil. The second is a polyethylene wax in the form of an aqueous emulsion containing a cationic emulsifier.
