Definitions
- the present invention relates to a method for fixing reactive dyes on cellulose-containing textile material.
- urea For the printing of cellulose-containing textile goods with reactive dyes, considerable amounts of nitrogen-containing compounds, in particular urea, are usually used as a solvent.
- the urea is particularly responsible for adequate fixation of the reactive dyes used.
- urea is an essential load factor in the waste water due to its nitrogenous degradation products.
- the printed fiber material fixed by the present method represents a further subject of the invention.
- the dyes used in the process according to the invention are the reactive dyes usually used for dyeing or printing cellulose textile materials.
- Reactive dyes are per se known dyes which form a chemical bond with the cellulose, e.g. the "Reactive Dyes” listed in Coulor Index in volume 3 (3rd edition, 1971) on pages 2391-3560 and in volume 6 (revised edition, 1975) on pages 6268-6345.
- Reactive dyes which are particularly suitable for the present process are those which contain a monohalotriazine group.
- the monohalotriazine group is a monofluorine, monobromine or preferably a monochlorotriazine group.
- reactive dyes which have one or more vinyl sulfone groups as the reactive group.
- the amount of the dyes generally depends on the desired color strength and is expediently 0.1 to 300 g / kg of printing ink, advantageously 0.1 to 100 and preferably 5 to 60 g / kg of printing ink.
- the printing inks contain fixing alkalis.
- alkaline compounds for fixing the reactive dyes are sodium carbonate, sodium bicarbonate, sodium hydroxide, disodium phosphate, trisodium phosphate, borax, aqueous ammonia or alkali donors, such as e.g. Sodium trichloroacetate or sodium formate used.
- a mixture of water glass and a 25% aqueous sodium carbonate solution can also be used as the alkali.
- the pH of the printing inks containing alkali is usually 7.5 to 13.2, preferably 8.5 to 11.5.
- the aqueous printing pastes used for the process according to the invention also contain thickeners, preferably of natural origin, in particular sodium alginate alone or in a mixture with modified cellulose, in particular with at most 20 to 25 percent by weight of carboxymethyl cellulose.
- the printing pastes can also contain preservatives, sequestering agents, emulsifiers, water-insoluble solvents, oxidizing agents and deaerating agents.
- the method according to the invention is suitable for fixing dyes on textile fiber materials which consist of or contain cellulose.
- these are mainly sheet-like textile materials, such as Fleeces, felts, carpets, knitted fabrics and in particular fabrics.
- the process according to the invention is suitable for fiber materials which may have been pretreated with sodium hydroxide solution, preferably for cellulose material and regenerated cellulose, such as Viscose cellulose.
- the printing paste is applied over the entire surface or in places directly to the fiber material
- printing machines of a conventional type e.g. Gravure printing, rotary screen printing and flat film printing machines can be used appropriately.
- the fiber material is dried at temperatures up to 150 ° C., preferably 80 ° to 120 ° C.
- the fiber material is evenly wetted with water on its top, back or on both sides.
- the water can be wetted in various ways, for example by direct or indirect application methods.
- the fiber material can be moistened directly by, for example, spraying on using a commercially available atomizer, by roller systems, stencils or by applying water in the form of foam or by so-called rotor dampening, the principle of which is described in detail in Textilpraxis Internarional, 111a (1987).
- the application amounts of water are between 5 and 50%, preferably between 10 and 40%, based on the printed, dry fiber material.
- the water used for wetting can be specially prepared by ion exchange resins or distillation. If desired, wetting or thickening agents can be added to the water.
- the water can also contain alkali.
- the printed and moistened fiber material is then subjected to a heat treatment according to claim 1 for fixing.
- the fixing method according to the invention can be carried out continuously or discontinuously.
- the fiber material as a rule a fabric web, can be sandwiched by a water-impermeable material from both sides and thus supplied to the heat treatment, or the fiber material lies on one side on a water-impermeable heating element and is on the side facing away from the heating element covered with a waterproof material.
- the heating element serves as a one-sided - or in the case of a press, if desired, a two-sided - barrier for the water vapor.
- the fiber material is enclosed in a water and vapor tight manner for the duration of the heat setting.
- the top and bottom are covered with a water- and vapor-tight barrier layer.
- Thin, heat-resistant and sublimation-resistant films come into consideration as water-vapor-tight material, which do not undergo any chemical reaction to the fiber material and the printing paste applied to it, as well as the dampening liquor. These foils are used to seal the printed fiber material tightly and thus prevent the water vapor from evaporating. Various materials can be considered. Polyester films are preferably used for the process according to the invention. Flat structures made of Teflon, metal or heat-resistant rubber can also be used to enclose the fiber material.
- the heat treatment is carried out continuously on a suitably modified calender or in a heated tunnel or discontinuously in a heated closed room or on a press, for example a transfer ironing press, for about 30 seconds to 20 minutes, preferably 5 to 10 minutes, with a contact pressure of about 0 , 2 to 2 bar.
- the fixing temperature is between 90 and 150 ° C, preferably between 100 and 110 ° C.
- the cellulose-containing textile material is then washed out in the customary manner in order to remove unfixed dye.
- the substrate is treated with water, preferably soft water, for example at from 20 ° C. to the cooking temperature.
- the fiber material is dried in the usual way.
- the heat required for the fixation can be supplied as contact, ambient or radiant heat to the fiber.
- Fixing by means of contact heat can be carried out in a simple manner by using devices that are already available in the textile operation for the continuous or discontinuous fixing process.
- the heat required for the fixation can be transferred as contact heat using a calender.
- the fiber material Before contact with the calender, the fiber material is covered on one or both sides with the water-impermeable film and passed over the calender. If the fiber material is covered on one side with the film, the surface of the calender serves as a second barrier layer.
- a water-impermeable endless belt is placed or pressed onto the calender and the fiber material to be fixed is drawn in between this belt and the calender.
- the heat required for the fixation can be transferred as contact heat by means of a press, such as a transfer ironing press. No or only slight modifications of the press are necessary to carry out the method according to the invention.
- the fiber material Before fixing, the fiber material can be sandwiched on both sides, covered with the waterproof film and then into the Press. However, it is also possible to equip one or both contact surfaces of the press with water-impermeable material and thus to carry out the fixing method according to the invention.
- the fiber material either has to be covered on one side only with the water-impermeable film or, if the press is water-impermeable on both sides, the appropriately moistened fiber material can also be inserted directly into the press.
- the heat required for the fixing process according to the invention can also be supplied as ambient heat.
- the waterproof, enclosed fiber material can be guided through a heated tunnel or enclosed in a heated room for the time required for fixing.
- the waterproof fixing of the fiber material enclosed in a watertight manner is also possible by means of radiation energy (infrared radiation, UV radiation or by means of microwaves).
- the watertight enclosed fiber material is either passed continuously through a tunnel heated by means of steel energy or intermittently enclosed in a room heated by means of steel energy during the time required for fixing.
- Example 1 A four-color pattern is printed on a bleached, mercerized cotton fabric.
- the resulting pattern-like print is dried for 2 minutes at 120 ° C.
- the pressure on the back is applied with 12% water, based on the weight of the fiber material, using a minimal application device.
- the moistened product is sandwiched between two polyester films and treated for 8 minutes at 105 ° C on an ironing press for fixing.
