Abstract

Cellulose esters or ethers, dyeing; textiles, treating with liquids; dye preparations.--The fastness of colourations on textile materials made of or containing organic esters or ethers of cellulose, particularly the fastness to the combined action of light and acid of colourations with anthraquinone dyestuffs containing amino, alkylamino or arylamino groups, is improved by applying thiourea to the materials before, during or after their colouration and retaining it in the materials during any subsequent finishing treatment. A further improvement in the fastness may be obtained by simultaneous or separate application to, or incorporation in, the materials of compounds having an alkaline reaction, e.g. borax, sodium carbonate, disodium hydrogen phosphate, sodium acetate, sodium palmitate or potassium oleate. Other substances adapted to increase the fastness of colourations may be employed with the thiourea, e.g. the substances used for this purpose according to Specifications 243,841, [Class 15 (ii), Dyeing, Processes &c. for], 340,541, 340,572, 355,726, or 361,362, or organic amines wherein an amino group is not attached directly to an aryl nucleus, e.g. mono-, di- and tri-benzylamines, monobenzylmethylamine, dibenzylmethylamine, dibenzyl - o - oxyethylamine, primary or secondary octylamine, amino derivatives of cycloparaffins, or compounds obtainable by the action of ammonia on halogenated higher aliphatic hydrocarbons may be employed with the thiourea. The thiourea may be applied in solution in water, alcohol or other organic solvent and up to 2 per cent may suitably be present in the finished material. It may be incorporated in dye preparations with or without dispersing agents and/or protective colloids. The following examples are specified: (1) A knitted cellulose acetate fabric dyed blue with 1 : 4 - di(methylamino)anthraquinone is impregnated in a bath containing 6 cc. per litre of sulphonated castor oil and 2 per cent of thiourea, and is centrifuged and dried. (2) A woven cellulose acetate fabric is dyed, padded in a bath containing per litre 2 grams of thiourea and 2 grams of borax, pressed to expel the excess liquid, dried and finished.
