Definitions
- This invention relates to a process for dyeing or printing natural and synthetic polyamides or polyamide-containing materials with the aid of an assistant which is characterized by good storage stability.
- Levelling assistants are usually surface-active textile dyeing auxiliaries which have the task of thoroughly wetting the fibre/fibre mixture to be dyed, of promoting penetration of the fibres and of preventing too rapid a strike of the dyes, which can lead to unlevelness, during the dyeing process.
- Suitable levelling assistants are, inter alia, oil sulphonates, fatty alcohol sulphonates, fatty acid condensation products, alkyl and alkylaryl polyglycol ethers and, generally, surface-active substances.
- Levelling assistants primarily reduce the rate of dyeing, increase the rate of dye migration within the fabric and improve the compatibility of the dyes.
- Levelling assistants can also have other effects which have no direct influence on the dye-fibre interactions, but nevertheless have a positive effect on the dyeing.
- Levelling assistants can exert two or more of the abovementioned effects at the same time.
- Levelling assistants can be divided into two groups, those which have an affinity to the fibre, or those which have an affinity towards the dye.
- Levelling assistants which have an affinity towards the dyes form an addition compound with the dye, the stability of which is dependent on the concentration and normally decreases with increasing temperature.
- the dye distribution equilibrium between the dye in solution and the dye in the fibre is therefore shifted to the dye in solution.
- the increased dye concentration in the dye solution permits areas of the fabric which have been dyed in a non-level manner to be evened out as a result of dye migration.
- Effective levelling assistants have an affinity towards the dye which is sufficient to reduce the rate of absorption or to increase the rate of migration. Differences in the absorption behaviour of different dyes can also be evened out, so that the dyes in a dye mixture strike uniformly.
- levelling assistants for wool are nonionic surfactants or weakly cationic, ethoxylated compounds.
- levelling assistants for wool are anionic compounds.
- Important dye-affinitive types of levelling assistants for polyamides are nonionic surfactants, cationic compounds or ethoxylated compounds.
- Important fibre-affinitive types of levelling assistants for polyamides are cationic compounds.
- Levelling assistants are preferably bought, stored and used in an aqueous composition. This presents certain problems particularly for storage.
- One such problem is creaming, i.e. inhomogeneties in the composition arise, which hinders use without prior treatment.
- the aim of the present invention is to provide a process which permits level dyeing or printing with an assistant characterized by excellent storage stability.
- Claimed is a process for dyeing or printing natural and synthetic polyamides or polyamide-containing compounds, characterized in that an assistant is used which comprises a compound of the formula (I)
- n 12 - 22
- the sum a + b +1 is between 20 and 50, preferably between 30 and 40
- m is 2 or 3, particularly preferably 3
- o is 2 - 5, more preferably 2 or 3, particularly preferably 2, or mixtures thereof.
- an assistant for dyeing or printing natural and synthetic polyamides or polyamide-containing materials which comprises a compound of the formula (I) or a mixture thereof.
- a preferred assistant has the composition
- Compounds or mixtures of the formula (I) are prepared by sulphation of an amino-C 2 . 6 -alkyl-(C 12 . 22 )amine ethoxylate, preferably amino-C 2 . 3 -alkyl-(C ⁇ 8 - 22 )amine ethoxylate having an average degree of ethoxylation of 20 - 50, preferably 30 - 40, with an excess of sulphamic acid with the addition of a solubilizer, preferably 1 -methyl-2-pyrrolidone.
- a storage-stable composition which comprises a compound according to formula (I) or mixtures thereof, characterized in that amino-C 2 . 6 -alkyl-(C 12 . 22 )amine ethoxylate, preferably amino-C 2 . 3 -alkyl-(C 18 - 22 )amine ethoxylate having an average degree of ethoxylation of 20 - 50, preferably 30 - 40, is converted by sulphation with an excess of sulphamic acid with the addition of a solubilizer, and is diluted with water.
- the examples below serve to illustrate the invention. Unless stated otherwise, the percentages are by weight, and the degrees are given in Celsius.
- a dyebath consisting of
- the resulting wool dyeing has an even appearance, excellent penetration and good manufacturing and performance fastnesses.
- a dyebath consisting of
- a dyebath consisting of
- the assistants according to the invention consisting of 40% of the formula (I) and 60% of water.
- the dyebath is heated to 98°C over the course of 30 minutes.
- 0.5 part of an anionic naphthalenesulphonic acid/formaldehyde condensation product is metered into the dyebath over the course of 20 minutes.
- the dyebath is cooled to 80°C over the course of 20 minutes, and the knit is rinsed and dried.
