Title: Improvements in or relating to lubricating compositions for and to the lubrication of textile materials
IPC: D06M13/256
Filed: 1937-06-23
Abstract: A lubricating composition for textile materials of organic derivatives of cellulose comprises a lubricating oil and a sulphonated naphthene and/or a salt thereof.  The lubricating oil may be a mineral, vegetable, sulphonated, or oxidized vegetable oil, or a mixture thereof, e.g. mineral oil blended with olive, castor, teaseed, cottonseed, oxidized olive, oxidized castor or sulphonated castor oil.  The composition may contain a fugitive dyestuff to identify the material to which it is applied.  A small amount of an amine soap such as triethanolamine oleate may be added to the composition as an emulsifying agent.  According to the Specification as open to inspection under Sect. 91, the lubricating composition may comprise a lubricant and a sulphonated fatty alcohol compound, e.g. a sulphate or sulphonic acid derivative of a fatty alcohol, or a derivative containing both sulphate and sulphonic acid groups, a salt of a sulphonated fatty alcohol, or a mixture of these compounds.  An organic electrolyte, such as a soap, or salt of an amine, for instance with a fatty acid or a sulphonated fatty alcohol, may be incorporated in the lubricant, which lubricant may be employed with fibres derived from cotton, wool or silk.  In examples, fibres produced by cutting continuous cellulose acetate filaments are sprayed with a lubricant comprising either (1) a mineral oil, a sulphonated fatty alcohol, oleic acid and triethanolamine, or (2) sulphonated olive oil, a sulphonated alcohol, triethanolamine oleate and triethanolamine.  An organic hygroscopic substance, e.g. a glycol or a glycol ether, may be added to the lubricant. This subject-matter does not appear in the Specification as accepted.ALSO:Textile materials of organic derivatives of cellulose are treated with a lubricating composition comprising a lubricating oil and a sulphonated naphthene and/or a salt thereof.  The lubricating oil may be a mineral, vegetable, sulphonated, or oxidized vegetable oil, or a mixture thereof, e.g. mineral oil blended with olive, castor, teaseed, cottonseed, oxidized olive, oxidized castor, or sulphonated castor oil.  The composition may contain a fugitive dyestuff to identify the material to which it is applied.  A small amount of an amine soap such as triethanolamine oleate may be added to the composition as an emulsifying agent.  The organic derivatives of cellulose may be cellulose acetate, formate, propionate, or butyrate, or methyl, ethyl or benzyl cellulose, and may be in the form of yarns, filaments or fibres.  The compositions may be applied to the materials in the course of their production, or may be applied before, during, or after an operation in which the materials are treated, e.g. by means of a wick, roller or disc, and may be incorporated in solutions from which the materials are spun by dry or wet spinning processes.  The lubricated materials may be treated with a conditioning dressing containing an oil, such as olive, castor, teaseed, or cottonseed oil, oxidized vegetable oils, or mixtures thereof, and a solvent or latent solvent for the cellulose derivative, e.g. a formal diacetone alcohol, benzyl alcohol or ethyl-a -oxy-isobutyrate.  In the examples, a spun yarn from a solution of cellulose acetate in acetone is contacted immediately after leaving the spinning cabinet with a wick dipping into a bath of the lubricant, the lubricated yarn is twisted in passing from one package to another and is contacted, in its passage, with a conditioning dressing containing a formal and an oxidized vegetable oil.  According to the Specification as open to inspection under Sect. 91, the lubricating composition may comprise a lubricant and a sulphonated fatty alcohol compound, e.g. a sulphate or sulphonic acid derivative of a fatty alcohol, or a derivative containing p  both sulphate and sulphonic acid groups, a salt of a sulphonated fatty alcohol, or a mixture of these compounds.  The organic derivatives of cellulose may contain pigments, dyes, lakes, fillers, plasticizers, fire retardants, and sizes.  An organic electrolyte, such as a soap or salt of an amine, e.g. with a fatty acid or a sulphonated fatty alcohol, may be incorporated in the lubricant, which lubricant may be employed with fibres derived from cotton, wool, or silk.  In examples, fibres produced by cutting continuous cellulose acetate filaments are sprayed with a lubricant comprising either (1) a mineral oil, a sulphonated fatty alcohol, oleic acid and triethanolamine, or (2) sulphonated olive oil, a sulphonated alcohol, triethanolamine oleate and triethanolamine.  An organic hygroscopic substance, e.g. a glycol or glycol ether, may be added to the lubricants.  This subject-matter does not appear in the Specification as accepted.
