Title: Improvements in textile lubricating and conditioning agents
Filed: 1948-03-24
Abstract: Lubricant additives consisting of a neutralized and desalted sulphonated mixture of a long chain aliphatic acid and vegetable oil, an alkyldamino-ester of a long chain aliphatic acid, and a neutralized partial ester of phosphoric acid with a long chain aliphatic alcohol are prepared as set out below.  The term "sulphonated" is used to cover reaction products which may contain sulphonic acid groups or sulphate groups or both.  The term "long-chain" is used to mean a carbon chain of at least 10 carbon atoms. Sulphonated mixture of a long chain aliphatic acid and vegetable oil.  Oleic acid and raw peanut oil in mineral oil solution are sulphonated with 20 per cent oleum at a temperature below 20 DEG C. as described in Specification 574,072.  Diamyl phenol, triethandamine and aqueous sodium hydroxide are then added.  The resulting mixture is desalted and dehydrated by addition of anhydrous isopropyl alcohol, the precipitated inorganic salts being filtered off.  The isopropyl alcohol and water are distilled off under vacuum as an azeotropic mixture, the still residue being further diluted with isopropyl alcohol, diatomaceous earth being added and the mixture filtered and redistilled under vacuum. Alkylolamine-ester of a long chain aliphatic acid.  Triethandamine is reacted at 150 DEG C. with cocoanut oil fatty acids in an atmosphere of CO2.  The reaction is stopped when the viscosity reaches about 430 seconds (measured in the Saybolt Universal Viscometer at 100 DEG  F.). Long chain aliphatic alcohol partial phosphoric acid ester. Phosphorus pentoxide is added gradually with stirring to lauryl alcohol in a jacketed reaction vessel at 105-110 DEG  C.ALSO:Textile fibres are conditioned and the formation of electrostatic charges thereon is prevented or minimized by treatment with an anhydrous composition free from inorganic salts and containing: (1) a mineral oil; (2) a long-chain aliphatic alcohol; (3) an alkyl phenol; (4) an alkylolamine; (5) a neutralized sulphonated long-chain aliphatic acid; (6) a neutralized sulphonated vegetable oil; (7) an alkylolamine ester of a long-chain aliphatic acid; and (8) a neutralized partial ester of phosphoric acid with a long-chain aliphatic alcohol.  The term "sulphonated" is used to cover reaction products which may contain sulphonic acid groups or sulphate groups or both.  The term "long-chain" is used to mean a carbon chain of at least 10 carbon atoms.  (For preparation of the sulphonated components (5 and 6), the long-chain aliphatic acid alkylolamine ester (7) and the long-chain aliphatic alcohol partial phosphoric acid ester see Group IV (b).)  Component (2) may be lauryl alcohol, (3) di-amyl phenol, (4) triethanolamine, (7) diethanolaminoethyl laurate and (8) mono-lauryl phosphate.  Preferred proportions are: (1) 55-65 parts by weight; (2) 2-10 parts; (3) 2-10 parts; (4) 2-5 parts; (5) and (6) combined 2-15 parts; (7) 10-30 parts; and (8) 2-12 parts.  The composition may be applied directly to continuous filaments emerging from a spinning cell.  It is particularly suitable for cellulose acetate but may be applied also to cellulose propionate, butyrate, acetate - propionate, acetate-butyrate and to ethyl and benzyl cellulose.  Other textile materials may be conditioned and lubricated with the compositions.  In an example, 195 parts by weight of acid refined white mineral oil having a Saybolt viscosity of 50 at 100 DEG  F., are blended with 29 parts of melted lauryl phosphoric acid, 26 parts of de-salted, dehydrated sulphonated reaction product obtained by reaction of oleum upon a mixture of oleic acid and raw peanut oil, 65 parts of diethanolaminoethyl laurate, 9 parts of triethanolamine, 8 parts of diamyl phenol and 18 parts of lauryl alcohol.  The composition is clarified by addition of 1.5 parts of diatomaceous earth and filtered.  Specification 574,072 is referred to.ALSO:Textile fibres are lubricated and conditioned with an anhydrous composition free from inorganic salts and containing (1) a mineral oil, (2) a long chain aliphatic alcohol, (3) an alkyl phenol, (4) an alkylolamine, (5) a neutralized sulphonated long chain aliphatic acid, (6) a neutralized sulphonated vegetable oil, (7) an alkylolamine-ester of a long chain aliphatic acid, and (8) a neutralized partial ester of phosphoric acid with a long chain aliphatic alcohol.
