Title: Improvements in or relating to lubricating and conditioning compositions for textiles
Filed: 1949-01-10
Abstract: A composition for conditioning and minimizing the development of electrostatic charges on textiles comprises a mineral oil, castor oil, a nuclear alkylated phenol, a long-chain aliphatic acid, and an alkylolamine, together with the constituents of a product obtained by reacting together a long-chain aliphatic acid, a vegetable oil, a mineral oil and sulphuric acid, neutralizing with an alkali and an alkylolamine and desalting and dehydrating the product.  "Long-chain" is defined as containing a chain of at least 10 carbon atoms.  Where the long-chain aliphatic acid is oleic acid, it should be of low linoleic acid content.  Oleyl alcohol or diethylene glycol monolaurate may be present as a blending agent.  An acylated vegetable oil or an acylated hydroxy-higher-fatty-acid in which the acyl group is that of a lower fatty acid may be added when the composition is to be used for conditioning.  "Higher fatty acid" and "lower fatty acid" are defined as containing at least 10 and up to 4 carbon atoms respectively.  Suitable esters for this purpose are the formyl, acetyl, propionyl and butyryl esters of castor oil, and butyl acetyl ricinoleate, employed in amounts of 1-10 per cent of the conditioning fluid mixture.  The viscosity of the final composition should be in the order of 80-200 S.U.S. at 100 DEG  F., which means that the mineral oil (which may be either paraffinic or naphthenic) should have a viscosity in the range of 50-75 seconds.  The mineral oil may form 50-75 per cent of the weight of the composition.  The alkylated phenol may be di-secondary or di-tertiary amyl-phenol or the branched chain dibutyl, di-secondary amyl and di-tertiary amyl derivatives of cresols and xylenols, and the branched dibutyl and di-amyl mono-chlorphenols. The amount of alkyl phenol may be increased to improve the spreading and setting properties of the composition, and when the hand of the yarn is important the amount of softening and conditioning agent should be increased.  The alkylolamine (tri-ethanolamine, or mixed isopropanolamines) and the long-chain aliphatic acid (oleic acid) are preferably added in stoichiometric proportions to form an amine soap (e.g. triethanolamine oleate). The de-salted dehydrated component is prepared by reacting oleum with a mixture of mineral oil, vegetable oil (olive, rice or peanut oil) and a long-chain aliphatic acid (oleic acid) at a temperature below 20 DEG  C., and on completion of the reaction, adding an alkylated phenol, and then an alkylolamine, and an alkali metal hydroxide to neutralize the remaining acid, finally de-salting and dehydrating with anhydrous isopropyl alcohol as described in Specification 574,072.  About 1-10 per cent of this mixture is used in the final composition.  The composition may be used for lubricating and conditioning textile materials made of cellulose acetate, propionate, butyrate, acetate-propionate, acetate-butyrate and ethyl and benzyl celluloses.  In an example (II) (all parts by weight), 55.6 parts of paraffin base white mineral oil (50 seconds viscosity), 18.5 parts of castor oil, 10.7 parts of oleic acid, 9.7 parts di-tertiary amyl phenol, 4.98 parts triethanolamine, 0.55 parts oleyl alcohol and 5 parts of the de-salted dehydrated component are mixed to give a lubricating and conditioning composition of viscosity 185 seconds at 100 DEG  F.ALSO:A textile lubricant comprises a mineral oil, castor oil, a nuclear alkylated phenol, a long-chain aliphatic acid, and an alkylolamine, together with the constituents of a product obtained by reacting together a long-chain aliphatic acid, a vegetable oil, a mineral oil and sulphuric acid, neutralizing with an alkali and an alkylolamine and de-salting and dehydrating the product.
