Definitions
- Textile material made from cellulose fibers are pretreated for dyeing according to the prior art Bleaching process, for example with hydrogen peroxide, in an alkaline medium.
- the bleached material is then dried, dyed and washed.
- cellulose textiles can be dyed and bleached at the same time.
- the treatment fleet contains Cubosol dyes, sodium nitrite, wetting agents and hydrogen peroxide stabilized with sodium metasilicate.
- the dye fixation and the bleaching are carried out simultaneously in a saturated steam atmosphere at 100 to 101 ° C. for 3 to 10 minutes.
- the invention further relates to the bleaching aids mentioned, consisting of components a), b) and optionally c).
- Such compounds are well known in the art. Some of them are used as leveling agents for dyeing anionic polyacrylonitrile fibers (see R. Rohkohl, Tenside 2 (1965) 76).
- the nonionic surfactants used are polyglycol ethers, for example EO / PO copolymers, sugar polyethers and alkoxylation products, in particular ethoxylation products of fatty alcohols, fatty amines, phenyl-styrene adducts, alkylphenols, fatty acids and fatty acid amides.
- the surfactants contain 4 to 100 alkenoxy groups, in particular 12 to 60 ethyleneoxy groups.
- the ratio of components a): b): c) is 1: 0.5-3.0: 0.00-1.0, in particular 1: 0.7-2.5: 0.1-0, 8th.
- cellulose-containing fiber materials can be dyed without pretreatment and then bleached in an alkaline medium.
- the new process enables the use of smaller amounts of dye, since the components according to the invention virtually prevent the dyes from bleeding out in the post-bleaching process.
- the cellulose-containing fiber materials used are dyed in the usual liquors with direct or reactive dyes, as are known in practice.
- this process can preferably be carried out as a wet-on-wet process.
- the amounts used by the mixtures mentioned vary within wide limits and depend, inter alia, on the process, the degree of bleaching to be achieved, etc.
- a bleaching liquor contains general the following substances familiar to the expert: MgSO4.
- 7 H2O nonionic detergent for example a reaction product of dodecyl alcohol with 4 moles of ethylene oxide NaOH H2O2 and optionally with the addition of SiO2. Na2O.
- the process parameters for the bleaching process generally look as follows: PH value 7.0-14, preferably 11.0-13.0 temperature 25-98 ° C, preferably 80-98 ° C time 5 - 180 min Fleet ratio 1: 1 - 1:40
- the mixture contains the organic acids as sodium salts and 49 parts of water.
- the dye yield is 40% higher.
- a knitted fabric made from 100% raw cotton is dyed with on the overflow 0.25% CI Reactive Yellow 111 0.80% CI Reactive Green 21 0.50% CI Reactive Blue 116.
- the liquor is heated to 90 ° C. with a gradient of 2 ° C./min. Treatment is carried out at this temperature for 30 minutes. The liquor is drained and soaped at the boil for 10 minutes with the addition of 0.5 ml / l of a 50% solution of 2-phosphonobutane-1,2,4-tricarboxylic acid and 0.5 ml / l of an anionic detergent. Finally, it is rinsed hot and cold.
- a bleaching process carried out according to this method is characterized by a 30% greater depth of dye than in the case of bleaching without the agents according to the invention.
