Definitions

  • the present invention relates to the local lightening, "white etching” or “colored etching” of dyeings on textile fabrics having a fibrous structure which have been dyed with the dyes suitable for the present type of fiber or have only been impregnated and dried but not yet fixed.
  • reducing agents such as, for example, stabilized hydrosulfite compounds or tin salts, or else alkalis, such as, for example, sodium hydroxide solution, are suitable as dye-destroying products.
  • alkalis such as, for example, sodium hydroxide solution
  • etching-enhancing products such as carriers or anthraquinone are also used in such etching pastes.
  • the task for the present invention is therefore to design a simple method according to which colorations with lighter pattern effects or "white or colored etchings" can be achieved without the disadvantages of the known method of operation described above occurring or those found thereby Restrictions have to be accepted.
  • the method explained above is primarily suitable for the treatment according to the invention of dyeings with disperse dyes on textile webs made of synthetic fibers.
  • fiber materials of synthetic origin are understood to be, for example, fabrics made of polyamide fibers, polyacrylonitrile fibers or cellulose triacetate fibers, but especially those made of polyester fibers, such as polyethylene terephthalate fibers, for use in accordance with the present invention.
  • disperse dyes used for this purpose such as, for example, azo, anthraquinone, quinophthalone or benzothioxanthene dyes, are well known and are described in the COLOR INDEX, 3rd edition (1971), volume 2 under the class name "Disperse Dyes”.
  • cellulose fiber materials are primarily used for those made of natural fibers, for those made from mixtures of natural fibers with synthetic fibers, mixtures of cellulose fibers with polyamide fibers,
  • the claimed method can be used for cellulose fibers which have been colored or impregnated with vat dyes, their leucoesters or with development dyes or (with the coupling component of development dyes), or for mixtures of cellulose fibers with synthetic fibers which have been colored or impregnated with disperse dyes, vat dyes or their leucoesters were.
  • the new process is carried out in such a way that, in addition to the usual thickening agents, other customary printing aids and water, the printing pastes used are auxiliaries of different constitution or auxiliary mixtures thereof which have dissolving properties for the dyes applied as a base at elevated temperatures and which have the particular fiber type do not attack yourself under thermosol conditions.
  • compounds of anionic, cationic or nonionic type can be used as characteristic, dye-dissolving auxiliaries.
  • Printing pastes are produced which, in addition to the usual proportions of water, contain thickeners and optionally other additives per kg, for example 20, 50 and 200 g of the auxiliary to be tested. These printing pastes are used to print on the test fabric which has already been dyed or merely impregnated with the dyestuffs (commercial form) intended for the base dyeing. After printing, the test stains treated in this way are thermosolated for 90-120 seconds at 210 ° to 215 ° C. and then rinsed in a customary manner and reductively cleaned. The results obtained can then be used to assess whether the aid in question is suitable for lightening effects alone or for both lightening effects and white effects.
  • oxyalkylated compounds preferably oxyethylated fatty alcohols, fatty acids or alkylphenols, and in particular those with 5 to 40 moles of ethylene oxide per mole of base substance, are particularly suitable for white effects.
  • Particularly useful for this purpose are fatty alcohols with 8 to 18 carbon atoms which are oxyethylated with 5 to 40 moles of ethylene oxide per mole of the alcohol.
  • the application amounts of the dye-dissolving aids in the printing pastes and the way in which the new process is carried out depend on the effects which are to be achieved. Depending on whether light or strong brightening effects or white effects are aimed for, application quantities between 5 and 200 g of product with the properties mentioned per kg of printing paste can be considered.
  • the type of heat treatment also plays an important role in achieving the desired results.
  • Thermosol treatment is the primary option. If only brightening effects are intended, the heat can also be carried out in the form of a steam process.
  • a steaming process s o so are mainly A ufhell bine, but barely reached white effects.
  • steaming can take place for 20 - 30 minutes under pressure at 1.5 - 2 atm (usually in a star steamer), about 8 minutes in superheated steam at 170 - 180 ° C (e.g. in a loop damper), about 10 minutes in saturated steam at about 102 ° C (in the star damper).
  • White effects are achieved if the printing process is followed by dry heat treatment, as is customary for fixing disperse dyes on polyester fibers using the so-called thermosol process, for example dry heating at 180-220 ° C for about two minutes.
  • the dry heat treatment can, for example, by means of hot air, heat rays and / or contact heat
  • the superiority of the new method is primarily due to the fact that it can produce very uniform lightening effects, the desired degree of lightening, depending on the given depth of color, by the type and amount of dye-dissolving aid and by the type and duration of the printing subsequent heat treatment can be affected.
  • the new method can be operated with relatively simple mechanical devices (for example magnetic squeegees in circular stencils) in dyeing plants, in which the machines required to apply dry heat are practically always available, while the dampers used for fixing according to the usual printing methods in dyeing plants are long not to the extent available in print shops.
  • the goods are steamed for 8 minutes in an HT steamer at 180 ° C and then washed. A print is obtained in which the printed areas are clearly lightened.
  • compositions of the printing pastes for the following examples correspond to those of Example 1, with minor modifications to the amounts of thickeners and water depending on the auxiliaries used in order to obtain printable pastes.
  • a fabric made of textured polyester fibers is coated with 1% of the red disperse dye of the formula after the pull-out procedure under. HT conditions dyed at 130 ° C for 60 minutes and then reductively cleaned as usual. The finished, dried dye is then printed with a printing paste which contains 150 g of oxyethylated stearyl alcohol (25 moles of ethylene oxide per mole of alcohol) per kg. After printing, the fabric is thermosolated at 215 ° C for 2 minutes and then washed. A print is obtained in which the printed areas are white.
  • the printed goods are finished by rinsing and reductive cleaning.
  • a print is obtained in which the printed areas are white.
