Definitions

• a prerequisite for the success of the process is that after the impregnation and intermediate drying of the fabrics, the dyes are evenly distributed in the textile material, otherwise uneven dyeings occur.
• a further prerequisite is that the goods are dried before thermosoling, since otherwise the thermosol temperatures cannot be reached by evaporation of the dyeing liquors.
• 0 - 5.0 g / l, preferably 0.5 - 3.0 g / l, of the thickener is used in component a).
• a thickening agent based on guar or locust bean gum derivative is preferred.

• This liquor is advantageously impregnated by padding to a weight gain of 60-250%, preferably 80-160%; the subsequent steaming in the wet state is advantageously carried out for 1 to 20 minutes in a saturated steam atmosphere of 96-105 ° C, preferably 98-102 ° C; then it is washed continuously at 20-60 ° C. advantageously in one to six baths, mechanically dewatered advantageously to 50-90% residual moisture and then dried advantageously for 1-10, preferably 2-6 minutes, at temperatures of 140-210 ° C. preferably 17 0-200 ° C.
• the process according to the invention is distinguished by the fact that all flat structures can then be colored and intermediate drying is not necessary. Due to the special liquor composition, it has become possible to dye polyester fibers that were previously not known by steaming continuously under the conditions mentioned. Such a method is not yet known and means both considerable technical and economic progress compared to the prior art (thermosol method).
• carrier-free dyeable polyester fibers and also flame-resistant modified polyester fibers.
• Carrier-free dyeable is understood here to mean that no “carriers”, i.e. components which act to accelerate diffusion, are added to the dyebath.
• carrier-free dyeable polyester fibers are modifications of conventional polyester fibers which are produced by the condensation of polyethylene glycols.
• the method is also suitable for dyeing blended fabrics made of polyester and cellulose fibers.
• Cellulose fibers are both native fibers, e.g. Cotton or linen, as well as regenerated fibers, e.g. Rayon or viscose, as well as esterified cellulose fibers, e.g. 2 1/2 acetate or triacetate understood.
• the fibers mentioned are in the forms of textile fabrics, such as Nonwovens, knitted fabrics or knitted fabrics, but especially as fabric, can be dyed.
• the textile fabrics can be both flat fabrics and, in particular, pile fabrics, such as Velvet, plush or velor. According to this method, pile fabrics are preferably dyed.
• the impregnation liquor is composed as stated in the main claim.
• Advantageous quantity ranges for the individual components are given on page 3 above.
• the dyes b) and c) can be used optionally or in combination.
• suitable thickeners are: nonionic and / or anionic products, such as those obtained by the addition of ethylene oxide, oxidative or thermal degradation or carboxymethylation of guar or locust bean gum.
• the products obtained by the addition of ethylene oxide are particularly suitable.
• Products with a degree of substitution of 0.3 - 0.7 are particularly suitable.
• disperse dyes for the process according to the invention. They can be used both as dispersed powders and as aqueous dispersions. Disperse dyes with a relatively large molecule and particularly high light fastness are particularly suitable. The disperse dyes can be used alone or in combination with direct dyes. From a chemical point of view, disperse dyes belong to the class of azo or anthraquinone dyes.
• all commercially available types can also be used as direct dyes. They are water soluble and can be of different chemical classes, e.g. Azo, anthraquinone or metal complex dyes belong.
• the dyes which are particularly suitable for the process according to the invention are selected on the basis of solubility, high color yield and maximum light fastness.
• Both the disperse and the direct dyes can contain the usual dispersing and grinding aids as well as blending substances or salts.

• the nitrile ethers preferably have a molecular weight of 100-250. in particular 150-200 and the oxyethylated chlorophenols from 150-400, in particular 200-300.
• polyester fibers are able to soften under the process conditions according to the invention. They therefore enable and accelerate the diffusion of the disperse dyes into the polyester fibers.
• component f) Commercial products of component f) are either pure substances or contain emulsifiers. Pure substances are added to the padding liquors with the aforementioned auxiliaries in a pre-emulsified form.
• Particularly suitable as component f) for the present process are di- and triethylene glycol monochlorophenyl ether and benzyloxypropionitrile.
• emulsifiers for component f preference is given to using oxyethylated C 16 -C 18 fatty alcohols with 10-25 mol of ethylene oxide.
