Wool is rendered resistant to felting by applying thereto 0.5-5% by weight of an acid chloride-containing polymeric shrink-proofing agent which is dissolved in a nonflamimable inert solvent, e.g. perchloroethylene, trichloroethylene, carbon tetrachloride or methyl chloroform, and then contacting it with water at a temperature of 70-100C for 0.5-10 minutes. The polymer used is a copolymer comprising (1) repeat units derived from α,#-ethylenically unsaturated monomers having the formula in which A is hydrogen, C 1 -C 8  alkyl, C 1 -C 8  alkoxy, aryl, chlorine, bromine, cyano, car boalkoxy, acyloxy, or aldehyde and B is hydrogen, methyl, chlorine or bromine and (2) units containing carboxylic acid chloride groups derived from alpha, beta ethylenically unsaturated carboxylic acids having 3-8 carbon atoms, the carboxylic acid chloride units being present in the copolymer in a proportion of 0-1- 50 mole per cent. The copolymers may be produced by copolymerizing an α,#-ethylenically unsaturated monomer, and an alpha, beta ethylenically unsaturated carboxylic acid containing 3-8 carbon atoms and converting the acid groups to acid chloride groups by reaction with carbonyl chloride, thionyl chloride, phosphorus trichloride or phosphorus pentachloride. The solution may 'be applied to the wool by padding, spraying or dipping and then centrifuging. The water may have a pH of 2-10 adjusted by for example the addition of acetic acid or sodium bicarbonate and the wool may be subjected to the treatment with water while held under tension so that it is stretched. The wool may be in the form of woven or knitted fabrics, garments, e.g. shirts, dresses, sweaters or socks, yarns, fibres or tops and may be blended with cotton, viscose rayon, polyester or acrylic fibres. Fabrics may be treated after carbonizing, after bleaching, after dyeing, before dyeing or after printing.

A photosensitive composition comprises a light-sensitive organic halogen compound of the formula R-C-X 3  where R is H, C1, Br, alkyl, aryl substituted alkyl or substituted aryl and X is Cl, Br or I, and a dye base having one of the following formulae:- wherein B is H or alkyl, R is an alkyl, aralkyl or aryl group, R<SP>1</SP> is H, CN or the radical R 1  and R 2  are alkyl or benzyl groups, d, e and g are 1 or 2,n is an integer from 1 to 4, L and L<SP>1</SP> are -CH= or -N= but at least one in each formula is -N=, or L is formula III may be -(CN)=, and Q, Z and Z<SP>1</SP> complete heterocyclic nuclei having 5 or 6 atoms in the ring. Exposure to light gives a coloured print-out image which may be enhanced by heating, which makes the image and non-image areas differentially soluble in selected solvents, so that either the unexposed or exposed areas may be washed away. In the latter case, the remaining unexposed areas may be re-exposed to give a positive image. Since the exposed areas are hydrophilic and the non-exposed areas are hydrophobic, the invention may be used for the production of lithographic printing plates. In the examples, the organic halogen compound is carbon tetrabromide or pentabromoethane and it may be coated in a binder of ethyl cellulose or eicosane. The colour images produced according to the invention may be converted into lakes by treatment with salts of copper, chromium, cobalt, phosphotungstic acid, phosphomolybdic acid of aluminium. Specification 959,037 is referred to.

Title: Paper-making process
IPC: D01D5/42
Filed: 1962-03-12
Abstract: Water-laid webs are made from fibres prepared from wet-spun filaments of an acrylonitrile polymer containing at least 80% acrylonitrile in the polymer by beating the fibres in aqueous suspension to fibrillate them, contacting them with a dilute aqueous solution of a strong mineral acid before or during the beating step and then depositing them to form a web.  The polymer may be polyacrylonitrile or a binary or ternary copolymer containing at least 80% of acrylonitrile, the balance being another olefinic monomer or monomers e.g. vinyl acetate.  The specification includes a list of emitable monomers. Alternatively, the polymer may be a blend of polyacrylonitrile or a copolymer with another copolymer which may contain less than 80% acrylonitrile or with cellulose acetate, so proportioned that the blend contains at least 80% of acrylonitrile.  The acid may be sulphuric, phosphonic, hydrochloric or nitric acid.  The fibres may be treated with the acid and then rinsed substantially free of acid before beating.  They may then be dried and stored before being beaten.  Alternatively, the acid may be added to the beater. The water-laid web may also contain other fibres, e.g. of cellulose, asbestos, glass or silk, which may be beaten separately from the acrylonitrile polymer fibres.  The polymer fibres may be collapsed by stretching or uncollapsed.  The strength of the product is improved by drying at higher temperatures, e.g. on a heated drum.  If necessary, anti-foaming agents such as octyl alcohol may be employed.
