Definitions

• the present invention relates to a process for printing cellulose-containing textile material with reactive dyes which contain at least one monohalotriazine group, the printing of the fiber material being carried out in a one-step process without the addition of urea.
• urea is an important load factor in the waste water.
• the present invention thus relates to a process for printing cellulose-containing textile material with reactive dyes which contain at least one monohalotriazine group, which is characterized in that the fiber material is printed in a one-step process without the addition of urea and the dried, printed goods are also used for the fixing process Water is moistened.
• Another object of the invention is the cellulose-containing textile material printed according to the process.
• the dyes used in the process according to the invention are a reactive dyes containing a monohalotriazine group, which are suitable for dyeing or printing cellulose textile materials.
• the monohalotriazine group is a monofluorine, monobromine or preferably a monochlorotriazine group.
• the amount of 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 When using reactive dyes, the printing inks usually 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 generally 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 carboxymethyl cellulose.
• the printing pastes can also contain preservatives, sequestering agents, emulsifiers, water-insoluble solvents, oxidizing agents and deaerating agents.
• Suitable preservatives are, above all, formaldehyde-releasing agents, such as, for example, paraformaldehyde and trioxane, especially aqueous, approximately 30 to 40 percent by weight formaldehyde solutions, and sequestering agents, for example sodium nitrilotriacetic acid, sodium ethylenediaminetetraacetic acid, especially sodium polymethaphosphate, in particular sodium hexamethaphosphate, as emulsifiers especially adducts of an alkylene oxide and a fatty alcohol, in particular an adduct of oleyl alcohol and ethylene oxide, as water-insoluble solvents, high-boiling, saturated hydrocarbons, especially paraffins with a boiling range of about 160 to 210 ° C (so-called mineral spirits), as an oxidizing agent, e.g.
• formaldehyde-releasing agents such as, for example, paraformaldehyde and trioxane, especially aqueous, approximately 30 to 40
• an aromatic nitro compound especially an aromatic mono- or dinitrocarboxylic acid or sulfonic acid, which is optionally present as an alkylene oxide adduct, in particular a nitrobenzenesulfonic acid and as a deaerating agent, for example high-boiling solvents, especially turpentine oils, higher alcohols, preferably C8 to C10 alcohols, terpene alcohols or deaerators based on mineral and / or silicone oils, in particular commercial formulations of about 15 to 25 percent by weight of a mineral and silicone oil mixture and about 75 to 85 percent by weight a C8 alcohol such as 2-ethyl-n-hexanol.
• a deaerating agent for example high-boiling solvents, especially turpentine oils, higher alcohols, preferably C8 to C10 alcohols, terpene alcohols or deaerators based on mineral and / or silicone oils, in particular commercial formulations of about 15 to 25 percent by weight of a mineral and silicone oil mixture
• the method according to the invention is suitable for printing on textiles which consist of or contain cellulose.
• these are mainly sheet-like textile materials, e.g. 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 wetted evenly 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 International, 111a (1987).
• the moistening can be carried out indirectly by bringing a cloth moistened with water in the damper into contact with the fiber material to be fixed.
• the cloth serves as a moisture carrier.
• the application amounts of water are between 5 and 50%, preferably between 10 and 40%, based on the printed, dry fiber material.
• the dyes are fixed on the material.
• the fixing is achieved by heat treatment of the material at temperatures of preferably 100 ° to 220 ° C.
• the heat treatment is generally carried out using steam under atmospheric pressure.
• the fiber material is generally washed by a cold and then a hot and, if necessary, a cold rinse.
• level and vivid color prints are obtained which are distinguished by an excellent product appearance.
• color prints with reactive dyes on cellulose-containing textiles, in particular viscose with the exclusion of urea, which is generally used in considerable amounts, can be achieved.
• Example 1 A fabric made from leached viscose is contained with a printing paste
• Example 2 A fabric made of bleached and leached cellulose viscose is made with a printing paste containing 25 g / kg of a commercially available granular formulation of the dye of the formula
• the desired color depth without additional moistening can only be obtained by adding 150 g / kg urea to the printing paste.
• Example 3 A printing ink is prepared according to the following recipe: 40 g of the dye of the formula
• Example 4 A cellulose fabric is printed and dried as described in Example 2. The water application is now only 10% (instead of 45%) of the Goods weight. A temperature of 102 ° C is maintained for the subsequent steaming process. The steaming time is 8 minutes. The turquoise shade resulting after washing has the same color strength as in Example 2. Omitting the moistening leads to a 40% brighter pressure drop.
