Definitions

• the purpose of the present invention is to obtain flawless white reserves when printing on natural and synthetic polyamide fiber materials and at the same time to create the possibility of clear color tones in the case of the production of colored reserves.
• German published patent application DE-A-28 46 247 a process is presented which relates to the production of white reserves with reactive dyes and of colored reserves with reactive and reactive dyes using aldehyde-alkali bisulfite adducts as a reservation agent.
• the examples to support this known technique all go with reactive dyes esterified ß-hydroxyethyl sulfone groups as the reactive radical, and in addition, it alone shows the application of the method described to cotton material.
• the ester dyes of the type used in many cases are unable to react sufficiently quickly with the reservation agent, transfer of this patterning method to wool does not always lead to perfect white reservation effects; this makes colored effects with a clear hue impossible in various cases.
• the vinyl sulfone dye is blocked immediately, so that this type of reactive dye is no longer able to react with OH, NH 2 and other groups.
• a bond to the fiber and a reaction with the fiber is no longer possible under these circumstances and thus there are excellent white reserve effects on the polyamide fiber material among the reactive dyes of the base coloring.
• reactive dyes of the halotriazine and halopyrimidine type and of a similar constitution of the reactive system do not react in the same way with the sulfite compounds, such dyes can be used colored reserves are generated.
• the implementation of the claimed method itself contains several possible variations.
• the reservable dye is applied to the material either by padding or splashing or by overpressure.
• the reservation agent must always be on the material.
• All water-soluble, inorganic sulfite compounds such as alkali and alkaline earth metal sulfites, all stabilized sulfite compounds and all organic, water-soluble or partially water-soluble sulfite compounds are suitable as reservation agents according to the present invention. Furthermore, as such reservation agents, all aliphatic and aromatic amines, all one and polyhydric alcohols of 2 to 10 carbon atoms and all inorganic and organic, water-soluble halogen compounds. Alkali sulfites or alkali bisulfites or stabilized sulfite compounds such as aldehyde-alkali bisulfite adducts are preferably used.
• suitable reservation agents are reaction products of bisulfite adducts of aldehydes with 2 to 6 carbon atoms or ketones and ammonia, primary or secondary amines in a molar ratio of 3: 1 to 1: 1, preferably bisulfite adducts of acetaldehyde and ammonia in a molar ratio 3: 1 to 1: 1, especially 1,1 ', 1 "-nitrilotriethansulfonic acid sodium and potassium.
• Dyes for the production of the colored reserve effects are those which are suitable for application to natural and synthetic polyamide fibers and are resistant to the above-mentioned reservation agents. According to the process, reactive, metal complex and acid dyes are used for this task. In a special test procedure, these dyes are selected before use in practice if they prove to be resistant to the aforementioned reserving products.
• the claimed process proceeds in such a way that either the white or the color reserve or the white and color reserves are pre-printed together.
• the converted vinylsulfone dyes are then overprinted onto this form reserve without drying, that is to say wet-on-wet, and then the textile material treated in this way is dried at 80 ° to 110 ° C. This is followed by steaming for 10 to 15 minutes to fix the design Saturated steam at 100 ° to 106 ° C; ammoniacal post-treatment of the dyeing completes the printing process.
• the white or colored reserves are pre-printed and then first dried at 85 ° C to 100 ° C. Then the material is padded with a padding liquor consisting of converted and activated vinylsulfone dye on the foulard or this is applied with the aid of a plating device and dried at 80 ° to 110 ° C. Steaming and aftertreatment are the same as for the former method.
• the vinyl sulfone dye of the second printing ink was previously dissolved with the stated amount of water at 80 ° C. and, after cooling to about room temperature, mixed with 11 g of sodium hydroxide solution at 38 ° Be. After stirring for 10 minutes, this solution was adjusted to pH 6.5-7 with 30% acetic acid, incorporated into the emulsion thickener and this printing ink applied.
• the printed material was dried at 80 ° C and then steamed at 102 ° C for 10 minutes.
• the aftertreatment was carried out in the form of an ammoniacal wash.
• a first printing ink corresponding to the composition of Example 1 was applied to a wool flannel fabric, but instead of the yellow dye there with 18 g of the reactive dye of the formula pre-printed and then wet-on-wet, ie without intermediate drying, the second printing ink from Example 1, including the same dye pretreatment, was overprinted.
• the wool fabric was padded in a gusset paddle with a liquor absorption of 85% (of the weight of the goods), then dried and steamed for 9 minutes at 104 ° C. with saturated steam.
