Definitions
- the present invention relates to the use of copolymers which contain at least 2 monoethylenically unsaturated monomers B1 and B2 in copolymerized form, B1 and B2 each containing at least one nitrogen-containing heterocycle, as auxiliaries for textile dyeing and textile printing.
- auxiliaries for textile dyeing are usually used in addition to colorants. Desired effects of auxiliaries for textile dyeing are, for example, the removal of unwanted dyeings. Other auxiliaries for textile dyeing ensure, among other things, particularly good and uniform dyeing and / or good exhaustion of the colorants.
- auxiliaries for textile dyeing are known to those skilled in the art as leveling agents.
- Other special examples of auxiliaries for textile dyeing are known to the person skilled in the art as stripping agents.
- Other special examples of auxiliaries for textile dyeing are known to those skilled in the art as soaping agents.
- Textiles - for example natural and synthetic textiles - are often not absolutely homogeneous in their composition, but have different compositions or thicknesses over the length of the threads. This can result in the textile having stronger and weaker colored areas after dyeing, which is generally undesirable.
- Leveling agents for example, are used to achieve a uniform color. These are understood to mean agents which produce a uniform dyeing over the surface of the textile to be dyed and especially over the length of the thread. Oil sulfonates, fatty alcohol sulfonates, fatty acid condensation products, alkyl and alkylaryl polyglycol ethers are known from the prior art as leveling agents.
- Leveling agents also influence the coloring behavior of the dyes, in particular the absorption behavior. Dyes with a high affinity for fibers should be retained longer in the fleet and migrate more easily on the fibers. It is desirable that leveling agents thereby lead to more uniform (“less important”) colorations.
- Leveling agents based on polyvinylpyrrolidone see. Ullmann's Encyclopedia of Industrial Chemistry (5th edition) Volume A26, page 291, left column.
- Other commercially available leveling agents are condensates of adipic acid and amines such as, for example H 2 N-CH 2 CH 2 -NH- (CH 2 ) 3-NH2 or H 2 -CH2CH2-NH- (CH 2 ) 3-NH-CH 2 CH2-NH 2 .
- the performance properties of such conventional leveling agents for example as leveling agents for leveling vat, direct, reactive or sulfur dyes, can still be improved.
- Peeling agents are generally understood to be those agents which are suitable for removing, for example, coloring, printing and impregnation by releasing, changing or destroying a dye.
- a particularly important area of application for release agents is the repair of incorrect stains. The dye is lightened on incorrect stains so that the incorrect stain can be recolored.
- Peeling agents are also known as a component of etching printing pastes. These are used to remove certain colors in etching printing. In etching printing, one color is usually printed over the entire surface. Then the next color is overprinted. The subsequent color is then removed in places with the help of an etching printing paste.
- Glauber's salt and / or sodium chloride in the soap bath Furthermore, the known after-soap agents must be used at high temperatures, i.e. around 98 ° C. The effect of the polyacrylic acids and polyvinylpyrrolidones used as soaping agents can also be improved.
- the object was therefore to provide an improved process for the subsequent cleaning of textiles dyed with reactive dyes, direct dyes or vat dyes, which are also referred to below as dyed textiles.
- the task was to provide after-soap agents with an improved effect in the after-cleaning of dyed textiles, which act especially with an increased concentration of salts in the soap bath.
- Glauber's salt and / or sodium chloride in the soap bath Furthermore, the known after-soap agents must be used at high temperatures, i.e. around 98 ° C. The effect of the polyacrylic acids and polyvinylpyrrolidones used as soaping agents can also be improved.
- the object was therefore to provide an improved process for the post-cleaning of textiles printed with reactive dyes, direct dyes or vat dyes, which are also referred to below as printed textiles. Furthermore, there was the task of providing after-soap agents with an improved effect in the after-cleaning of printed textiles, which act especially when there is an increased concentration of salts in the soap bath.
