Definitions

• the present invention now relates to a continuous dyeing and printing process for textile material made of wool and / or cellulose with fiber-reactive dyes, which is characterized in that the textile material in the wet state on one side with an auxiliary carrier with colored drawings or a university - Pattern is made of fiber-reactive dyes and on the other hand briefly in.Kontakt with a heated pad, the temperature being selected so that no boiling of the solvents on the textile material, in particular water, occurs.
• an auxiliary carrier for example, a thin metal foil, in particular a thin aluminum foil or, which is even more advantageous for economic reasons, a paper or cellophane foil or a paper tape.
• the dyes in the form of aqueous or organic-aqueous inks are optionally applied to the production of multicolored drawings or motifs and dried according to the usual in Pa p ier horrerei known methods.
• the auxiliary carrier printed in this way is brought into contact with the wet materials to be printed and heated to a maximum of 98 ° C. for 15 to 60 seconds.
• the prints applied to the auxiliary carrier are transferred to the textile material to be dyed.
• a contact time of 30 seconds at 85 to 98 ° C., preferably 90 to 95 ° C., under atmospheric pressure is sufficient.
• fiber-reactive dyes are e.g. those described in DE-AS 19 12 632 are suitable.
• Reactive dyes with halogenotriazinyl radicals which can carry phenoxy, alkoxy or alkoxyalkoxy radicals, with heterocyclic radicals, with sulfonyl leaving groups and with fluorine-containing heterocycles are particularly preferred.
• the dyes can be applied to the auxiliary carrier as indicated above and this can then be used for transfer printing.
• the materials to be dyed or printed according to the present process can be in the form of woven, knitted or non-woven fabrics, and as foils or films.
• the keratin materials, such as wool, must be chlorinated, the padding liquor should be so acidic that a pH of 2, for example through H 2 S0 4 , is reached.
• Cellulose-containing materials, such as cotton and viscose are advantageously provided separately with the amount of alkali required for fixing the fiber-reactive dyes and, if appropriate, a catalyst, or together with the amount of water provided to achieve the wet state.
• the most expedient procedure is that the textile materials to be dyed are first impregnated with the padding liquor (e.g. by padding), the excess amount of the padding liquor is removed, for example by squeezing, and the wet product obtained in this way is pressed with the printed auxiliary carrier between the heated cylinder and the printing blanket D.
• the padding liquor e.g. by padding
• the excess amount of the padding liquor is removed, for example by squeezing, and the wet product obtained in this way is pressed with the printed auxiliary carrier between the heated cylinder and the printing blanket D.
• the printed materials can be subjected to damping or heat setting in a dry manner in order to fix the dyes better. After washing, unfixed dye components and any aids can be removed.
• the parts mean parts by weight, percentages, percentages by weight, and the temperatures are given in degrees Celsius, unless stated otherwise. The same ratio exists between the part by weight and the part by volume as between gram and milliliter.
• a wet strength paper (65-70 g / m 2 ) is printed with an aqueous printing paste which contains 1000 parts x parts of a highly reactive reactive dye and 400 parts of 5% sodium alginate.
• the subcarrier After drying, the subcarrier is finished and has an unlimited shelf life.
• the substrate to be printed a chlorinated wool fabric
• an aqueous padding liquor containing 1000 parts of 13 parts of a thickener based on hydroxyethyl cellulose, 10 parts of a nonionic wetting agent, 10 parts of a leveling agent based on an aliphatic oxyethylation product and as much 10% sulfuric acid contains a pH of 1.5 to 2.
• the fleet intake should be 110%.
• the auxiliary carrier and the pretreated wool fabric are passed through together between a cylinder heated to a maximum of 95 ° C. and a pressed printing blanket.
• the contact time with the cylinder should be approximately 30 seconds.
• the auxiliary carrier is then removed and the wool fabric is steamed with saturated steam for between 10 and 15 minutes. After washing and drying you get a perfect print.
• Suitable dyes are, for example: Yellow: or CI 18971 red: Blue: CI 61205
