Definitions

  • This invention relates to an improved process for the resist or discharge printing of synthetic textile materials.
  • Resist printing is a method of textile printing in which an undyed textile material is first printed with a substance (the resist) which prevents the uptake or fixation of a subsequently applied dyestuff, so that there is obtained a white pattern on a coloured ground, or a pattern of contrasting colour to the ground by incorporating suitable dyestuffs or colour-producing substances in the resist print paste.
  • a substance the resist
  • Discharge printing is a method of textile printing in which dyed textile material is printed with a chemical composition (the discharge) that destroys the dyestuff locally to give a white pattern, or in which a second dyestuff, applied simultaneously with the discharge, produces a pattern of contrasting colour.
  • GB-A-1543724 describes and claims a process for producing discharge printing effects in a coloured ground shade on a synthetic textile material, which comprises applying to that area of the material where the ground shade and the discharge effect are wanted one or more disperse dyes which contain at least one carboxylic ester group but are free from carboxylic acid and sulphonic acid groups, and in a separate stage applying to the material where the discharge effect is wanted a printing paste which is alkaline or becomes alkaline on heating or steaming and which does not contain any reducing agent, thereafter heating or steaming the material and thereafter washing the material.
  • stages 1 and 3 can be reversed, so that the dyestuff is applied to the textile material before the alkaline print paste.
  • stage 5 in which the textile material is subjected to the action of heat or steam, the disperse dyestuff in contact with the alkali is converted into a water-soluble form, whilst the disperse dyestuff which is not in contact with the alkali is fixed on the textile material.
  • the water-soluble form of the dyestuff is then removed from the textile material by the washing treatment of stage 6.
  • stage 2 it would be desirable if, in the above process, the first drying operation (stage 2) could be eliminated so that stage 1 is followed immediately by stage 3.
  • This "wet-on-wet" process would have the advantages that the process has one stage less, with consequent saving in drying plant occupation time, and also the saving in the energy used to effect drying.
  • GB-A-1481741 describes the production of multicolour effects using alkali sensitive disperse dyes of a different type to GB-A-1543724 applied in conjunction with alkaline agents.
  • wet-on-wet resist or discharge prints having sharp definition between the different coloured areas of the print can be obtained if the alkali used in the print paste is sodium or potassium silicate and if specific types of alkali dischargeable dyestuffs are applied.
  • a process for producing resist or discharge printing effects on a synthetic textile material which comprises applying to the textile material, in either order (i) an alkaline printing paste which may contain one or more disperse dyestuffs free from sulphonic acid, carboxylic acid and carboxylic acid ester groups, the said dyestuffs being unaffected by alkali at the concentration present, and (ii) a printing paste or passing liquor containing at least one alkali dischargeable disperse dyestuff free from sulphonic acid and carboxylic acid groups, and free from carboxylic acid ester groups which if hydrolysed would leave free carboxylic acid groups attached to the dyestuff molecule, thereafter heating or steaming the material and thereafter washing the material characterised by the presence of sodium or potassium silicate in (i), a carboxylic acid in (ii), and without drying between the application of (i) and (ii).
  • alkali-dischargeable dyestuffs which are used in the process according to the present invention may be broadly classified as follows:
  • miscellaneous dyestuffs C.I. Disperse Violet 88, C.I. Disperse Yellow 180, C.I. Disperse Violet 48, C.I. Disperse Blue 92, C.I. Disperse Yellow 93, C.I. Disperse Yellow 201, C.I. Disperse Yellow 88, C.I. Disperse Yellow 210, C.I. Disperse Red 203 and C.I. Disperse Yellow 202.
  • dyestuffs which may be used in the present process are those which discharge only partially (i.e. do not give a white discharge) and which do not leave a weak enough stain to allow all shades of illumination to be used, but which do show an even residual shade that allows the use of such dyestuffs for limited illuminated shades and which may be used for shading purposes.
  • miscellaneous dyestuffs of formulae Red which is disclosed in GB-A-859899, and Red which is disclosed in GB-A-1027968, together with C.I. Disperse Red 72, C.I. Disperse Blue 139, C.I. Disperse Orange 55, C.I. Disperse Red 329 and C.I. Disperse Violet 40.
  • Any disperse dyestuff which undergoes chromophore destruction in the presence of alkali to an extent such as to make it suitable for a ground shade in discharge printing may be used in the present process, provided that it is free from -COOH, -S0 3 H and -COOR- groups as defined in claim 1.
  • the sodium silicate which is used in the above process may be any of those grades of sodium silicate which are commercially available and is preferably a sodium silicate in which the molecular ratio of SiO 2 to Na 2 0 is from 1.65:1.0 to 4.0:1.0.
  • the potassium silicate which is used preferably has a molecular ratio of Si0 2 to K 2 0 of from 2.0:1 to 4.0:1.
  • the amount of sodium or potassium silicate which is used in the printing paste (I) must provide sufficient alkali to discharge the disperse dyestuff in the padding liquor or printing paste (ii), and may be from 50 to 300 parts by weight per 1000 parts by weight of printing paste.
  • a sodium or potassium silicate having a high molecular ratio of SiO 2 to Na 2 0 or K 2 0 can be replaced in the printing paste by a smaller quantity of sodium or potassium silicate having a lower molecular ratio of Si0 2 to Na 2 0 or K 2 0, without affecting the result.
  • the printing paste containing the sodium or potassium silicate may also contain a humectant such as ethylene glycol urea or, preferably, glycerol, a dye solvent such as polyethylene glycol, for example, a polyethylene glycol having a molecular weight in the region of 300, and a thickening agent.
  • a humectant such as ethylene glycol urea or, preferably, glycerol
  • a dye solvent such as polyethylene glycol, for example, a polyethylene glycol having a molecular weight in the region of 300
  • a thickening agent e.glycerol
  • suitable thickeners are starch derivatives such as starch ethers, carob-seed gum ethers, modified carboxymethylcelluloses and combinations of these, optionally in admixture with water-in-oil or oil-in-water emulsion.
  • the padding liquor or print paste used to apply the alkali-dischargeable disperse dyestuff will also contain a carboxylic acid, for example, citric acid, to prevent premature interaction of the dyestuff with the alkaline sodium or potassium silicate, and may contain a thickener such as one of those thickeners already mentioned above.
  • a carboxylic acid for example, citric acid
  • a thickener such as one of those thickeners already mentioned above.
  • adjuvants which are conventionally employed in the application of disperse dyestuffs to synthetic textile materials from such media, for example carriers, fixation assistants, level dyeing assistants, dispersing agents and antifoam agents.
  • the heat treatment to which the textile material is subjected after the application of the print paste containing the sodium or potassium silicate and the print paste or padding liquor containing the disperse dyestuff can comprise a heat treatment for a short period at temperatures from 150° to 220°C. It is, however, preferred to subject the textile material to a steaming treatment, for example, saturated steam at 100°C for a few minutes followed by a dry heat treatment at 160° to 220°C or superheated steam at 150° to 200°C, or the use of saturated steam under pressure at 115° to 150°C.
  • the synthetic textile material used in the process of the invention can be in the form of nonwoven fabric, felt, woven or knitted goods, or carpets.
  • synthetic textile materials there may be mentioned secondary cellulose acetate and cellulose triacetate, polypropylene, acrylic, polyamide, and preferably aromatic polyester textile material.
  • the alkali-dischargeable disperse dyestuff can be used together with a reactive dye whose reactive groups, such as sulphato- ethylsulphone groups, form a dye-fibre bond with the hydroxyl groups of the cellulose textile material which is hydrolysed under the alkaline conditions in those areas where the alkaline print paste is applied, or a reactive dyestuff containing one or more phosphonic acid groups which does not fix on cellulose in the presence of alkali.
  • a reactive dye whose reactive groups, such as sulphato- ethylsulphone groups, form a dye-fibre bond with the hydroxyl groups of the cellulose textile material which is hydrolysed under the alkaline conditions in those areas where the alkaline print paste is applied, or a reactive dyestuff containing one or more phosphonic acid groups which does not fix on cellulose in the presence of alkali.
  • the disperse. dyestuff or dyestuffs which are optionally used in the alkaline printing paste containing sodium or potassium silicate can be any of the disperse dyestuffs free from -S0 3 H, --COOH and ⁇ COOR groups (as defined in claim 1) and not adversely affected by alkali which are conventionally employed in colouring synthetic textile materials. Examples of such dyestuffs are given in, for example, the Third Edition of the Colour Index which was published in 1971.
  • a resist print paste comprising: is printed on to a woven polyethylene terephthalate textile material, and without drying the textile material is then coated over all, including that part which has already been printed with the above resist paste, with the following print paste comprising:
  • the textile material is then dried on drying cylinders for 2 minutes at approximately 95°C, high temperature steamed at 170°C, for 8 minutes, washed off using the six-stage washing sequence described above and finally dried.
  • the resulting blue on white pattern has excellent definition.
  • sodium silicate used in the above example is replaced by the same amount of a sodium silicate in which the molecular ratio of Si0 2 to Na 2 0 is 1.65:1.0 a similar result is obtained; the amount of this latter sodium silicate can also be reduced to 100 parts without adverse effect on the sharpness of the resulting print.
