Patent GB-431964-A (GB)
Title: Improvements in dressings for textile materials
IPC: D06M13/02
Filed: 1934-07-03
Abstract: A textile lubricant comprises a substantially water-insoluble oil or fat or higher fatty acid and a small proportion of an aromatic compound containing an unsaturated aliphatic substituent group.  The unsaturated group may be vinyl, propenyl, allyl, or crotonyl for example, and the aromatic compound may contain other groups such as hydroxy, ether, halogen or sulphonic groups. Substituted phenol, cresol, naphthol, catechol and resorcinol, for example, or substituted phenol ethers such as anisole and phenetole may be used, and especially the propenyl, allyl, vinyl and crotonyl derivatives of aromatic compounds containing both ether and hydroxy groups, e.g. guaethol and guaiacol.  Animal or vegetable oils of fats, e.g. olive, castor, coco-nut, and neatsfoot oils, and in general glycerides of oleic, stearic, palmitic or other higher fatty acids, or the acids themselves may be used.  Assistants such as mineral lubricating oils, glycol, diethylene glycol, glycerine, and other polyhydric alcohols may be employed.  The quantity of the aromatic compound may be 0,5--5 per cent by weight of the oil, fat or fatty acid.  The textiles treated may be filaments, yarns, or fabrics of cellulose esters or ethers, or artificial materials such as foils, bristles, horsehair, or straw.  The lubricant may be added to the spinning solutions which are spun by wet or dry methods, or to the formed materials.  Thus cellulose acetate filaments may be treated continuously with their production by dry spinning methods e.g. by passing over wicks.  A composition consisting of olive oil 99 parts, and propenyl guaethol 1 part by weight, for example, is applied to a cellulose acetate yarn by passage over wicks, rollers or other devices while in transit from the spinning machine to a winding device.  The amount of the finish applied may be from 1--2 per cent by weight of the yarn.  Reference has been directed by the Comptroller to Specification 346,267.ALSO:A textile lubricant comprises a substantially water-insoluble oil or fat or higher fatty acid and a small proportion of an aromatic compound containing an unsaturated aliphatic substituent group.
