DE2844250A1 - Simultaneous dyeing and resin treatment of cellulose fibres - with substantive or acid dyes and methylol resins - Google Patents

Abstract

Process is effected continuously by treatment with an aq. soln. contg. (a) 1-20 g/l of a substantive or acid dyestuff; (b) 40-200, pref. 50-200 g/l of methylol melamine and/or methylol-ethylen urea precondensate; nc) 10-30 g/l of an acid catalyst, free from metal salts, for the condensn. of the resin; (d) 5-20 g/l of an anti-migration assistant; (e) 0-30 g/l of a non-ionic plasticiser; (f) 0.5-5 g/l of an anionic or non-ionic wetting agent. The material is then dried and immediately fixed at 140-170 degrees C; pref. 155 degrees C. Post-washing is not necessary. Natural and regenerated cellulose fibres, opt. admixed with synthetic fibres, e.g. polyester are dyed and rendered resistant to creasing, shrinking and deformation simultaneously without separate intermediate stages. Higher prodn. efficiency is thus obtd.

Process for simultaneous dyeing and resin treatment of cellulosic fiber materials

It is known from DE 16 19 321 to dye cellulose fiber materials at the same time with direct dyes and to equip them with amino resins. However, such processes require intermediate storage in the moist state before drying and fixing, since otherwise there will be irregularities in the coloration.

The aim of the invention is to use a continuous process while avoiding interim storage too even To get dyeings on cellulose fiber materials.

The subject matter of the invention is thus a process for the simultaneous dyeing and treatment of cellulose fiber materials, characterized in that the cellulose fiber materials are used in a continuous process

The process is suitable for dyeing textiles made from natural or regenerated cellulose fibers, possibly mixed with synthetic fibers such as polyester. The known and commercially available substantive dyes or acid dyes, such as CI. Direct Red 218, CI. Direct Orange 39 > CI: Direct Black 112, CI. Direct Red 84 used.

The dye liquor contains about 1-20 g / l dye.

Methylolmelamine or methylolethylene urea precondensates for finishing cellulose fiber materials are also known and commercially available. They are applied to make the cellulose materials crease-proof, shrink-proof and dimensionally stable. Ground suitable products obtained by known methods by reacting 1.5 to 4 moles of formaldehyde with melamine or dihydroxyethylene urea or a mixture of melamine and dihydroxy ethylene urea.

The required amount is around 50 - 200 g / l liquor.

Hydrochlorides are used as metal salt-free catalysts organic amines, e.g. 2-amino-2-methyl-1-propanol hydrochloride, Monoethanolamine hydrochloride or diethanolamine hydrochloride used. The required amount is about 10 - 50 g / l liquor, depending on the amount of resin.

To achieve a high level of color uniformity the fleet also contains an anti-migration aid. In particular, polyacrylamides with a molecular weight of 100,000-1,000,000 are suitable for this purpose. The used The amount is about 5-20 g / l liquor.

Furthermore, the liquor can contain up to JO g / l of a nonionic plasticizer. For example, a 25% polyethylene dispersion, a 20% fatty acid amide polyglycol ether emulsion or a 20% fatty acid amide emulsion can be added. The grip of the textile material is thereby favorably influenced.

Finally, an anionic or nonionic wetting agent is added to the liquor in an amount of 0.5-5 g / l added. For this purpose, the commercially available wetting agents known for textile purposes come into consideration, such as z. B. alkyl sulfates, alkyl sulfonates or alkylarylsulfonates with 10-20 carbon atoms, or adducts of 5-20 moles of ethylene oxide with higher alcohols or alkylphenols with 10-20 carbon atoms.

The impregnation, drying and fixing of the fiber material takes place in a continuous process without intermediate storage. For example, the goods are impregnated on a three-roll pad with a liquor volume of 70 fo. Then on the stenter or in a continuous hanging dryer at 90 - 120, preferred
