Abstract: A textile sizing composition comprises an aqueous solution of polyvinyl alcohol, a substance which causes the size to retain water, e.g. glycerol, sorbitol, pentaerythritol, polyethylene glycol and urea, a lubricant composition and a conditioning composition.  The lubricant composition is compounded from mineral oil, oxidized vegetable oil such as oxidized peanut, olive, or teaseed oil, or oxidized sperm oil, a higher fatty acid such as oleic acid, a dialkyl phenol such as 2,4-di-sec.-butyl phenol, 2,4-di-tert.-butyl phenol, 2,4-di-sec.-amyl phenol, or 2,4-di-tert.-amyl phenol, an alkylolamine such as triethanolamine, a fatty acid of more than 10 carbon atoms such as oleic acid, and optionally butyl acetyl ricinoleate and oleyl alcohol.  The conditioning composition consists of the desalted, dehydrated, alkalineutralized reaction product of oleum with a mixture of a mineral oil, a fatty acid of more than 10 carbon atoms such as oleic, ricinoleic, or palinitic acid, and a vegetable oil such as olive, rice or peanut oil, the product being diluted after sulphonation with a mineral oil; optionally the conditioning composition may also contain a dialkyl phenol such as 2,4-di-tert.-amyl phenol.  Specification 571,490 is referred to.ALSO:A conditioning composition for use in sizes is prepared by reacting oleum with a mixture of a mineral oil, a vegetable oil, such as olive, rice, or peanut oil, and a fatty acid of more than 10 carbon atoms, such as oleic, ricinoleic or palmitic acid, at the completion of the reaction a dialkyl phenol may be added as a stabilizer and antioxidant.  The reaction product is neutralized with alkali, desalted with a solvent such as isopropyl alcohol, and the solvent and water are then distilled off; prior to distillation a filter aid such as bentonite or diatomaceous earth may be added and the solution filtered.  In an example, a mixture of mineral oil, raw peanut oil, and oleic acid is reacted with 20 per cent oleum at a temperature not above 25 DEG  C.; at the completion of the reaction 2,3-di-tert.-amyl phenol is added and the mixture is neutralized with sodium hydroxide, isopropyl alcohol is added, the precipitated inorganic salts are filtered off, and the isopropyl alcohol and water are distilled off under vacuum; diatomaceous earth is added to the still residue the mixture is filtered and the distillation repeated to remove traces of isopropyl alcohol and water.  Specification 571,490 is referred to.ALSO:The lubricating compositions described in Specification 571,490 are employed in sizing compositions containing an aqueous dispersion of polyvinyl alcohol, a substance which causes the size to retain water such as a polyhydric alcohol or urea, and a conditioning agent consisting of the neutralized reaction product of oleum with a mineral oil, a vegetable oil, and a higher fatty acid, the product being diluted with mineral oil.  The lubricating compositions described consist of a mixture of a mineral oil, an oxidized vegetable oil such as oxidized peanut, olive or teaseed oil or oxidized sperm oil, an alkylolamine such as triethanolamine, a fatty acid of more than 10 carbon atoms such as oleic acid, a dialkyl phenol such as 2,4-di-sec. butyl phenol, 2,4-di-tert. butyl phenol, 2,4-di-sec. amyl phenol, or 2,4-di-tert. amyl phenol, and optionally butyl acetyl ricinoleate and oleyl alcohol.
