Definitions

• the invention relates to a textile printing method in which a textile fabric preferably colored dark with a basic dye and in a pattern area is provided with a printed pattern.
• the invention further relates to a reserve or etching ink for application to a textile Sheet.
• the invention is based on the object in the state the disadvantages of the technology to avoid and the textile printing of Motifs on a dark or colored background largely without design To enable restrictions with the least possible production effort.
• the invention is based on the idea of controlling inkjet printing Do not color or keep the motif free of the basic color. Accordingly, it is proposed according to the invention that the Reserve ink applied to sample area by inkjet printing with the reserve ink being permanently fixed in the pattern area of the basic dye prevented. Alternatively, it is provided that the pattern area an etching ink is applied by ink jet printing, wherein the etching ink in the pattern area destroys the basic dye.
• the reserve ink Reserving agents based on sulfites, sulfite adducts, thiourea or Preparations thereof.
• the etching ink contains a suitable reducing agent, in particular sulfoxylates.
• the basic dye is formed by a vinyl sulfone dye.
• the full coloring of the fabric with the basic dye can by a block process before or after the reserve or Etching ink done. This allows brilliant colorations with high color strength receive.
• the textile fabric is preferred subjected to a fixation treatment by the action of saturated steam.
• a pH regulator can preferably be selected from the group soda, hydrogen carbonate, Sodium hydroxide solution, water glass or potassium carbonate can be activated.
• An embodiment of the invention provides that the print pattern as a white reserve or white etching is formed.
• colored dyes alternatively, preferably based on monochlorotriazines, it is possible that the print pattern is formed as a color reserve or color sets.
• the print head is working line by line, with a large number of parallel channels or pressure nozzles are present to different colors printed closely side by side Print dots additively a halftone dot as the pixel of a digital image or to create a motif.
• the reserve or etching ink a viscosity regulator based on glycols, especially polyethylene glycol or contains polyacrylates
• a viscosity in the range from 2 to 10 mPas is favorable for the formation of drops at the nozzle.
• the reserve or etching ink may contain a preferably nonionic surfactant.
• the reserve or etching ink hygroscopic additives such as urea or Contains glycerin. Biodegradation, for example, by bacteria delayed because the reserve or caustic ink is a preservative like contains formaldehyde.
• the reserve or etching ink advantageously contains demineralized water as a carrier.
• the conductivity of the Reserve or etching ink is less than 60 mS / cm.
• Another aspect of the invention resides in a reserve ink for application on a textile fabric by inkjet printing, preferably containing one Reserving agent based on sulfites or sulfite adducts to inhibit the fixation of a basic dye.
• Yet another object of the invention is an etching ink to be applied to a textile fabric by inkjet printing, containing a reducing agent, in particular Sulfoxylates to destroy a basic dye.
• a preferred use of a reserve or etching ink according to the invention lies in digital textile printing on a dark background using inkjet technology.
• a suitable etching ink contains a reducing agent instead of the reservation agent, especially sulfoxilates to destroy the base dye.
• the ink Before use, the ink should be degassed using ultrasound to ensure an undisturbed flow through the ink channels.
• the textile is pre-padded with a thickener solution based on natural alginates or based on synthetic thickener systems and then dried.
• the pre-block fleet is composed as follows: 5 - 50 g / kg Na alginate as a thickener; 0-150 g / kg Urea to increase depth of color; 3 g / kg Complexing agents, for example based on polyphosphates; x g / kg Water demineralized.
• the squeezing effect should be around 80%.
• the padded goods are, as described above, with the inkjet printer the reserve ink and possibly additionally monochlorotriazine colored dyes printed.
• the squeezing effect should be approx. 80%.
• the fixation takes place under saturated steam conditions or with superheated steam in 2 up to 10 minutes. Then the prints, as with reactive dyes usual, washed to the boil.
• the goods are padded with a padding liquor that contains an alkali dispenser (sodium trichloroacetate or sodium hydrogen carbonate) and the vinyl sulfone dye intended for the fund as well as an anti-migration aid, according to the following recipe example: 10 - 80 g / kg Vinylsulfonfarbstoff; 0-150 g / kg Urea; 3 - 20 g / kg Phosphate; 5 - 50 g / kg alginate; 10 - 100 g / kg Alkalis; x g / kg Water.
• an alkali dispenser sodium trichloroacetate or sodium hydrogen carbonate
• vinyl sulfone dye intended for the fund as well as an anti-migration aid
• the product comes with a fund dye and alginate or synthetic Block liquor containing thickener and then dried.
• Recipe example for the pre-block fleet 10 - 80 g / kg Vinylsulfonfarbstoff; 0-150 g / kg Urea; 0-10 g / kg Ludigol; 5 - 50 g / kg alginate; 2 g / kg Monosodium phosphate (pH 6-7) as a buffer; x g / kg Water.
• the padded goods are printed with the inkjet printer as described.
• the prints are fixed with an alkaline and saline padding liquor padded and then fixed in saturated steam.
