Description

The present invention relates to a continuous process for dyeing or finishing textile fiber materials, preferably with a pronounced three-dimensional character (pile and pile materials) and in particular carpets, using foam.

From EP-A1-9240 a foamable preparation is known which contains a predetermined amount of a finishing agent and at most 10% by weight of a foamer and the ratio of the active substances to the foamer mentioned being at least 8: 1.

or

wherein m, n and p represent 10 to 100.

From GB-A-2 027 753 a method for treating textile fiber materials with the aid of foam is known, in which a foamed preparation is used which contains a special combination of surface-active agents, which are defined by chemical and physical parameters. The foams described therein are characterized in particular by the fact that they have foam half-lives of more than 60 minutes. Specific anionic and nonionic surfactants can be used as foaming components. Non-ionic block polymers which can be used according to the invention and thus the foam composition combination according to the present invention are, however, not disclosed in GB-A-2 027 753.

In the unpublished EP-A1-30 919 a method for dyeing or finishing textile fiber materials is described, in which an aqueous foam-forming preparation is used, which (a) as a foam stabilizer 1 to 4 g / l of an anionic or nonionic surfactant or one Mixture of these surfactants and (b) as foam moderator contains 0.1 to 1 g / l of a siloxaneoxyalkylene copolymer. Such preparations are accepted by the present invention.

The foams are generally applied at room temperature, i. H. around 15 to 30 ° C. Based on the treated fabric, the foam application is generally 10 to 200, in particular 60 to 160 percent by weight.

For the dyeing or finishing of the textiles, a treatment liquor is foamed and the foam is brought from a foam container, preferably with an adjustable doctor blade, to the front of the fabric via an application roller. First of all, the substrates can be prewetted at room temperature or prewashed or pre-bagged at temperatures up to 80 ° C.

If desired, the foam application can be repeated on the back of the fabric. In this case, intermediate drying between the application on the front and that on the back is not necessary. It is also possible to apply different treatment liquors to the front and back of the textile.

Advantageously, for the treatment of pole materials, e.g. B. carpets, before the foam application, the substrate with a preferably a non-ionic surfactant z. B. a C _a -C ₂₂ fatty acid alkanolamide or an adduct of 1 to 100 moles of ethylene oxide with 1 mole of a C ₈ -C ₂₂ fatty alcohol or a C ₄ -C ₆ alkylphenol or a pretreatment liquor containing C8-C22 fatty acid and / or a preferably foaming agent, in particular components (A) and (B), prefouling dye liquor containing. The impregnation is preferably carried out with a liquor absorption of 40 to 120 percent by weight. The subsequent foam application is generally 40 to 180 percent by weight, preferably 50 to 150 percent by weight. After pre-fouling the substrate with an impregnating liquor, which may already contain a foaming agent, and then applying foam, one can successfully dispense with sucking the foam into the textile material and carry out the heat treatment, preferably steam treatment, directly.

After the foam application and dewatering of the foam, the substrate is subjected to a heat treatment, e.g. B. subjected to temperatures of 95 to 210 ° C. After an intermediate drying at 80 to 180 ° C., preferably 80 to 120 ° C., the heat treatment can be carried out by heat setting (dry heat) at a temperature of 120 to 210 ° C., preferably 140 to 180 ° C. Preferably the heat treatment is direct, i.e. H. without intermediate drying, by steaming at 98 to 120 ° C, with a short, uniform foaming over the goods when entering the steamer, which preferably lasts 4 to 25 seconds and thus prevents unwanted gray veils. Depending on the heat development and the temperature range, the heat treatment can take 30 seconds to 10 minutes. If desired or necessary, the dyes or finishing agents can also be fixed using a chemical bath or a metal bath.

After the heat treatment, the textile material can be washed out in a conventional manner in order to remove unfixed dye or unfixed finishing agents. For this purpose, the substrate is treated, for example, at 40 to 80 ° C. in a solution that contains soap or synthetic detergent.

The process according to the invention is used to obtain level dyeings with good wet and light fastness or well-equipped fiber materials with the aid of foam. Since relatively little moisture is applied during foam dyeing compared to the conventional continuous process for carpets, in which the amount of treatment liquor is up to 500%, based on the substrate, a shorter heat treatment and thus a higher production speed is now possible.

When equipping, there is also an improvement in the relationship between the achievable effect (e.g. in the case of refinement) and the loss in strength compared to conventional padding applications.

Furthermore, the wastewater in the dyeing and finishing plants is only slightly contaminated thanks to the small amount of liquid, which is valuable from the ecological point of view. The saving in water and energy is also an advantageous consequence of the method according to the invention.

In the following examples, the percentages are by weight unless otherwise specified. The amounts of the dyes relate to commercial, i.e. H. Coupled goods and for components (A) and (B) on pure substance.

The speed of the goods is 8 m / minute. The layer height of the foam is 7 mm. The color foam application is 150%.

The carpet then goes through a vacuum passage in which the foam layer is partially sucked into the carpet from the back (negative pressure of 0.1 bar), which reduces the height of the foam layer somewhat. The carpet then runs over a transport roller to a damper, the foam layer on the carpet disintegrating even before the damper is reached. The foam is re-foamed at 98 ° C for 5 to 10 seconds. The carpet is then treated with saturated steam at 98 ° C for 4 minutes. The carpet is then sprayed with water at 80 ° C., then suctioned off and dried at 100 ° C. on a sieve drum dryer.

The result is an olive, level, streak-free carpet dyeing with excellent coloring from the tip of the pole to the backing of the carpet.
