Title: Non-migrating size compositions
IPC: C03C25/321
Filed: 1961-02-23
Abstract: A non-migrating size composition, e.g. for glass fibres, comprises as the principal filmforming ingredient a starch fraction composed substantially of one of the two components of starch known as amylose and amylopectin.  The size composition, which is preferably applied in a water base, may include the following constituents by weight: oils (0-2,0%); surface active emulsifying agents (0,1-1,0%); lubricantsofteners (0,1-1,0%); additional film-forming materials (0-0,4%); plasticizers (0-1,0%) and water 87-98%).  Oils: animal or vegetable oils, or other oleaginous material; emulsifying agents: polyalkylene compounds such as polyoxyethylene sorbitan mono-oleate and other equivalent compounds; lubricant-softeners: cationic materials such as condensates of tetraethylene pentamine with stearic or pelargonic acid which are solubilized with acetic acid, or the chlorides, acetates, bromides, dibasic acid salts and salts of primary, secondary and tertiary amines, quaternary ammonium compounds, and of phosphonium and sulphonium compounds; additional film-forming materials: polyvinyl alcohol or gelatin (preferred), copolymers of acrylonitrile and styrene, vinyl chlorides and acetates, vinyl chlorides or nitriles; cellulose derivatives such as acetates, nitrates and alkyl cellulose; polyamides; polyalkylenes and their halogenated derivatives; polyvinyl compounds, polystyrene and polyacrylates; plasticizers: polyalkylene glycols, fatty acid esters of glycols, organo phosphates such as tricresyl phosphate, phthalic acid derivatives, chlorinated paraffins, other glycol and glycerol derivatives and the esters or derivatives of the following acids: adipic, fumaric, maleic, oleic, azelaic, benzoic, citric, sebacic, phosphoric, ricinoleic, stearic, sulphonic and tartaric.  Examples are directed to the preparation of size compositions containing the following ingredients: (1 and 4) amylose, vegetable oil, polyoxyethylene sorbitan mono-oleate, octadecyl amine acetate, polyethylene glycol or alternatively gelatin and polyvinyl alcohol, and water; (2 and 3) amylopectin, vegetable oil, polyoxyethylene sorbitan monooleate, octadecyl amine acetate, polyethylene glycol or alternatively gelatin and polyvinyl alcohol, and water.ALSO:A non-migrating size composition, e.g. for glass fibres, comprises as the principal filmforming ingredient a starch fraction composed substantially of one of the two components of starch known as amylose and amylopectin.
