GB393769A - Improvements in or relating to liquids or plastic preparations for the treatment of fibrous materials - Google Patents

Abstract

The wetting, cleansing, foaming, and dispersing power of liquids and plastic preparations used for the treatment of textiles, leather, or other fibrous materials is improved by the addition of synthetically prepared glucosides derived from sugars or polymeric carbohydrates and aliphatic alcohols having more than five carbon atoms, cycloaliphatic or aromatic alcohols or substitution derivatives thereof, such as halogen, amino or carboxy derivatives. When the glucosides are insoluble, they may be dispersed with sulphonated oils, soaps or other dispersing agents and inorganic salts and solvents may also be present. In examples: (1) a bath for washing raw wool contains the sodium salt of ricinoleic sulphuric ester and lauryl glucoside; (2) a dye bath for cotton contains Sirius blue G, soda, sodium sulphate, the sodium salt of lauryl sulphuric ester and lauryl glucoside; (3) a spinning flux comprises an emulsion of olein, cetyl glucoside, turkey red oil and water. The glucosides may be prepared by known general methods, e.g. lauryl alcohol is refluxed with acetobromglucose and quinoline and after cooling shaken with ether and sulphuric acid; the resulting glucoside is recovered from the ether solution. They may also be prepared direct from the sugar by treatment with a solution of hydrochloric acid in the alcohol. When starch is employed, it is treated with hydrobromic acid, acetylbromide and glacial acetic acid so as to produce acetobromglucose. The use of fructose and mannose, and also any monohydric or polyhydric primary, secondary or tertiary alcohol containing more than five carbon atoms is mentioned. The Specification as open to inspection under Sect. 91 comprises also the use for the same purposes of any glucoside derived from an aliphatic alcohol with more than five carbon atoms, or cycloaliphatic or aromatic alcohols or phenols. This subject-matter does not appear in the Specification as accepted.ALSO:The dispersing and cleansing power of liquids and plastic preparations used for the treatment of textiles, leather or other fibrous materials is improved by the addition of synthetically prepared glucosides derived from sugars or polymeric carbohydrates and aliphatic alcohols having more than five carbon atoms, cycloaliphatic or aromatic alcohols or substitution derivatives thereof, such as halogen, amino or carboxy derivatives. When the glucosides are insoluble, they may be dispersed with sulphonated oils, soaps or other dispersing agents and inorganic salts and solvents may also be present. In an example, a spinning flux comprises an emulsion of 9 lb. of olein, 0.5 lb. of cetyl glucoside, 0.5 lb. of turkey red oil, and 100 lb. of water.
