Definitions

• This invention relates to a new wool dyeing process and more particularly to a new process for dyeing wool in a continuous manner.
• the alkali metal dedecyl benzene sulphonate used in the process is preferably the sodium salt; it is to be understood that by dodecylbenzene sulphonate there are included the commercially available materials of this name which are not pure substances but mixtures of homologues and isomers in which the main constituents are dodecylbenzene sulphonates in which the dodecyl radical can be straight chain or branched.
• the normal range of usage of this assistant lies between 1% and 5% by weight of the padding liquor.
• the preferred condensates of ethylene oxide with an alkyl phenol are those in which from 5 to 15, and more particularly 7.5 to moles of ethylene oxide, condensed with an alkyl phenol in which the alkyl radical or alkyl radicals contain from 5 to 12 carbon atoms, above all those having an octyl or nonyl radical, for example, an octyl or: nonyl phenol or an octyl cresol.
• the normal range of usage of this assistant lies between 1% and 20% by weight of the padding liquor.
• salts well-known as equivalents thereto in dyemg wool for example ammonium sulphate, ammonium acetate and ammonium phosphate.
• a suitable quantity of acid or salt is, for example, from 0.5 to 2% by weight of the padding liquor.
• other well-known adjuvants to dyestufi padding solutions, as used for the dyeing of other fibers for example, thickeners such as sodium alginate and solubilismg agents, such as urea.
• the new dyeing process can be used. to apply all kinds of wool dyestuffs to the fibre; for example, anthraquinone, monoazo, 1:1-meta1 complex monoazo and 1:2-metal complex monoazo dyestuffs having up to 2 sulphonic acid groups, can, in general, be used.
• As fibres which may be dyed there may be mentioned combed slivers, also fabrics, both knitted and woven piece goods.
• the new dyeing process can conveniently be carried out by slop-padding the wool through. the dyestuff solutron, removing excess of solution by passage through rollers and subjecting the wool to a steaming treatment for aperiod of time necessary to fix the dyestutf on the fibre, usually from 15 to 30 minutes being sufficient.
• the process of the invention enables the production of strong, dyeings of an excellent standard of levelness, much superior to those obtained by the use of an alkali metal dodecyl benzene sulphonate alone or an ethylene oxide/alkyl phenol condensate alone.
• Example 1 W001 slubbing is passed through a solution at 20 C. containing 10 parts of the mixed 1:2-chromium complex of 1-(5'-chloro-2-hydroxyphenylazo)-2-naphthol and 6- (4-nitro 2'-hydroxyphenylazo)2-acryloylamino-5-naphthol-7-sulphonic acid, 10 parts of a condensate of 9.5 moles of ethylene oxide with nonyl phenol, 10 parts of sodium dodecyl benzene sulphonate and 7.5 parts of sodium alginate per 1000 parts of liquor, and then wrung out to a liquid content of on the dry weight of wool. It is then passed into a chamber heated to 100 C. with steam and steamed for 20 minutes. A level brown dyeing free from surface frostiness is produced.

A level well penetrated dyeing results.
• the 5 parts of sodium alginate can be replaced equally by 5 parts of carboxymethyl cellulose, and the 5 parts of acetic acid can be equally replaced by 20 parts of ammonium dihydrogen phosphate.
• the condensate of 3 4 octyl phenol with 7.5 or 8.5 moles of ethylene oxide there can be used the condensate of 3 4 octyl phenol with 7.5 or 8.5 moles of ethylene oxide, a Example 6 similar result being obtained.

• the 10 parts of acetic acid may be replaced equally well by 20 parts of oxalic acid.
• a process for dyeing wool by padding the wool in an aqueous acidic solution of a water-soluble wool dyestufi and fixing the dyestufi. on the fibre by steaming, wherein the padding solution contains at least 1% by weight of an alkali metal dodecylbenzene sulphonate and at least 1% by weight of a condensate of ethylene oxide with an alkyl phenol wherein there are from 5 to 15 moles 10 of ethylene oxide per mole of alkyl phenol.
