Abstract
Abstract A size for lubricating fibers, including glass fibers, which is a water dispersion of a solid unctuous material, as for example a solid wax, fat, or gelled or otherwise solidified oil, and a starch ether of a cyclic hydrocarbon, as for example a starch ether of an aryl compound, an aralkyl compound, an alkaryl compound, a cycloalkyl compound and a cycloalkenyl compound, or homologues thereof. The wax may be an animal, vegetable, mineral, or synthetic wax which is unctuous and insoluble in water. The oils can be gelled by adding any gelling agent, and preferably a thixotropic gelling agent to the oil. The starch ethers or, as the case may be, are only partially cooked so that unburst starch granules are retained, and this dispersion is intimately mixed with the unctuous solid emulsified particles. Other ingredients such as cationic lubricants, coloring matter, bactericides, waxes having particular characteristics, etc. can be added to provide their separate functions. The combination of the above defined partially burst starch granules of etherified starch, and the emulsified particles of the solid unctuous material have very low migration from coated glass fibers, and when dried, provide low tensions when pulled over guide surfaces.
