Title: Improvements in or relating to water-soluble cellulose ethers and process for their preparation
IPC: C08B11/22
Filed: 1961-03-09
Abstract: In the preparation of water soluble hydroxy alkyl cellulose ethers, the cellulosic material is contacted with an alkali, etherified, and the cellulose ether purified by neutralising the alkali with an acid and then removing the salts formed and other impurities with a suitable solvent, characterized by using acid/solvent combinations selected from (1) propionic acid in combination with a 70-90% by weight aqueous solution of isopropyl alcohol, tert.-butyl alcohol, or sec.-butyl alcohol, and (2) benzoic acid, nitric acid, or acetic acid/nitric acid mixture in combination with a 70-90% by weight aqueous solution of isopropyl alcohol, tert. butyl alcohol, sec. butyl alcohol, acetone, or dioxane.  Preferably the hydroxy-alkyl cellulose is hydroxy ethyl cellulose and is prepared by a slurry process wherein the alkali treatment and etherification of the cellulosic material are carried out in the presence of an inert organic diluent as slurry medium.  In preferred methods, the acid is a mixture of 98-80% by weight (especially 98-90%) nitric acid and 2%-20% by weight (especially 2-10%) acetic acid.  In examples, the substitution level of the hydroxy alkyl cellulose is 2.5-2.7 moles etherifying agent (e.g. alkylene oxide) per anhydroglucose unit, and purification is effected either by washing the impurities out of the slurry or by dissolving the cellulose ether in a solvent and re-precipitating it therefrom. If desired, the viscosity of the hydroxyl alkyl cellulose may be reduced, before purification, by treatment with hydrogen peroxide.  Hydroxy alkyl cellulose so made has an enhanced resistance to colouration, especially at elevated temperatures.

Abstract: A fully-fashioned garment or garment portion is slackly knitted on a straight-bar machine from two yarns in plating relationship, the yarns comprising a face yarn plated on a backing yarn having a relatively high extensibility but capable of being relaxed or shrunk. On completion the garment or garment portion is subjected to a finishing process which effects a permanent relaxation or shrinkage of the backing yarn with the result that the face yarn has its loop structive compressed into a smaller unit area.  The face yarn can also be extensible such that during the finishing process it relaxes or shrinks to a certain extent but only to the extent such that its loop structure is still compressed into a smaller unit area by the contraction of the backing yarn.  The face yarn may be wool, rayon or polynosic or a linen slub yarn exhibiting a boucle effect.  The backing yarn may be a polyamide, polyester, acrylic, P.V.A. or processed polyester.  The finishing treatment may involve subjecting the garment to dry heat or bulking in hot detergents at temperatures less than or up to boiling point.  Alternatively the garment may be subject to steam setting.
