Definitions

  • -natural polyamide fibres refers in particular to filaments, yarns, woven fabrics or knitted goods of wool or silk.
  • synthetic fibres dyeable with acid dyes are understood the aforenamed textile forms of synthetic polamide fibres, e.g. nylon 6, 7, 1 1, 66, 76, 226, 610 and 6/66, of basic modified polypropylene and of basic modified polyacrylonitrile and acrylonitrile copolymer fibres.
  • the colourless fibre-reactive compounds employed for impregnation contain a colourless organic radical of any desired type which may bear substituents and/or hetero atoms, is preferably not appreciably volatile at 100C, and has attached to it a group which reacts readily with a nitrogen atom of the textile material for reservation.
  • Suitable compounds of this type include heterocyclic compounds having 1 or 2 exchangeable halogen atoms, for example those of the formulae Hal
  • Hal stands for F, Cl 01 Hr, X for a group of one of the formulae Y for H, F or Cl; Z for an unsubstituted amino group,
  • V represents a phenyl radical which may be substituted by, e.g., C1 or CH and compounds containing aliphatic groups and a double bond capable of addition or an exchangeable halogen atom, e.g. those of the formulae the textile colourist will be guided by these known criteria.
  • V represents a phenyl radical which may be substituted by, e.g., C1 or CH and compounds containing aliphatic groups and a double bond capable of addition or an exchangeable halogen atom, e.g. those of the formulae the textile colourist will be guided by these known criteria. 1
  • the compounds are applied by a printing process, the known method of print paste preparation for dyes is employed.
  • Water-insoluble compounds are applied in aqueous dispersion.
  • they are preferably ground to an average particle size of about 0.1 to 10 microns or more particularly 0.1 to 5 microns, if necessary in the presence of dispersing agents or fillers.
  • the dry compounds can be ground with a dispersing agent and if required fillers,'or alternatively it can be kneaded in paste form with a dispersing agent and subsequently vacuum or jet dried.
  • an acid-binding agent such as sodium or potassium carbonate or bicarbonate
  • One of the commonly used thickening agents is normally included in the padding liquor or printing paste, for example modified or unmodified natural products, such as sodium alginate, British gum, gum Arabic, crystal gum, locust bean gum, gum tragacanth, starch, carboxymethyl-cellulose or hydroxyethyl-cellulose, or synthetic products, such as polyacrylamides or polyvinyl alcohols.
  • modified or unmodified natural products such as sodium alginate, British gum, gum Arabic, crystal gum, locust bean gum, gum tragacanth, starch, carboxymethyl-cellulose or hydroxyethyl-cellulose, or synthetic products, such as polyacrylamides or polyvinyl alcohols.
  • the padding liquor or printing paste may contain the colourless fibre-reactive compounds in amounts of up to about 150 parts per 1,000 parts. Fixation is effected preferably in a moist atmosphere at room temperature for periods of up to about 20 hours, or between 25 and 95C for 2 hours, or between 95 and 130C for about 15 minutes.
  • Polyamide materials treated with the colourless fibrereactive compounds can be dyed with anionic dyes; the areas of the material treated with the compounds then remain undyed or are dyed to lighter depth than the remaining material, depending on the degree of reservation imparted by the treatment.
  • the best reserve effects are obtained against anionic dyes bearing two or more sulphonic acid groups; in fact 100 percent reservation of synthetic polyamide fibres can be obtained against this type of dye.
  • a step by step decrease in the degree of reservation is obtained with dyes bearing only one sulphonic acid group and with premetallized dyes. This process of reservation has no effect on disperse dyes I which give the normal effects obtained with this class,
  • basic dyes dye the reserved areas of polyamide material to greater depth than the unreserved substrate.
  • the material can be subsequently dyed with anionic dyes and then with basic dyes to produce two-colour effects, since the latter class preferentially dyes the areas reserved against anionic dyes.
  • the reverse procedure is of course practicable, with the basic dyes being applied first to dye the reserved areas, followed by anionic dyes to fill in the remaining material. Dyes of these two classes can be applied from the same bath if desired.
  • Example 1 Carpet yarn of texturized nylon 66 fibre is locally im pregnated with a paste of the following composition at a pressure giving a 100 percent increase over the dry weight on the impregnated areas:
  • the paste Before application the paste is vigorously stirred until homogeneous.
  • the impregnated yarn is stored for 2 hours at room temperature (2025) and then rinsed with cold water. It is tufted in a jute fabric and the tufted carpet exhaustion dyed with two dye mixtures, one of C.l. 11855 Disperse Yellow 3 and C.l. 17045 Acid Red 37, the other of CI. 61505 Disperse Blue 3 and C.l. 17045 Acid Red 37. In this way a two-colour dyeing is obtained.
  • Example 2 A printing paste of the following composition:
  • sodium alginate thickening 40 parts sodium bicarbonate, anhydrous 804 parts water,
  • the fabric thus locally preserved against anionic dyes, is cut into five equal parts and these are dyed, respectively, with the following dyes:
  • Example 6 A paste is prepared with 5 parts sodium alginate thickening 30 parts disodium phosphate (anhydrous) 2 parts monosodium phosphate (anhydrous) 917 parts water 8 parts octylphenyl-pentaglycol ether 2 parts modified sodium alkylsulphate 9 parts 2,4-dichloro-6-phenylamino-l,3,5-triazine,
  • Example 7 A printing paste is prepared with the following additions and vigorously stirred until homogeneous:
  • the paste is printed on a nylon 6 fabric by the Vigoureuxprocess at a coverage of 25 percent and a pressure giving a percent increase over the dry weight on the printed areas.
  • the fabric is stored for 24 hours at room temperature (2025) and rinsed with cold water. It is then exhaustion dyed with C.l. Acid Red 37, which results in a pale red dyeing on the treated and a dark red dyeing on the untreated areas.
  • Example 8 1 Carpet yarn of texturized nylon 66 fibre is'impregnated at a l00 percent increase over the dry weight on the impregnated areas with a homogeneously stirred paste of the composition:
  • the yarn is stored for 2 hours at 40, rinsed with warm and cold water, and dyed with C.l. 61505 Disperse Blue 3 and C.l. Acid Red 37 to produce a twocolour effect on the treated and untreated areas respectively.
  • Example 9 Texturized nylon 6 yarn in package form is locally impregnated with a homogeneously stirred liquor of the following composition at a 100 percent increase over the dry weight on the printed areas:
  • Example 10 A printing paste is prepared with 5 parts sodium alginate thickening 30 parts anhydrous disodium phosphate 2 parts anhydrous monosodium phosphate 933 parts water 8 parts octylphenyl-pentaglycol ether 2 parts modified sodium alkyl sulphate parts 2,4-dichloro--phenylamino-l,3,5-triazine dispersed with parts sodium dinaphthylmethanedisulphonate,
  • the paste is vigorously stirred until homogeneous and printed locally on nylon 66 yarn at a 100 percent increase over the dry weight on the printed areas.
  • the yarn is then treated for 4 minutes at 98, rinsed with warm and cold water, and dyed in the normal way with C]. Acid Red 57.
  • the treated areas are of pale red shade; the untreated, dark red.
  • Example 1 l A paste is prepared with 5 parts sodium alginate thickening parts anhydrous disodium phosphate 2 parts anhydrous monosodium phosphate 944 parts water 8 parts octylphenyl-pentaglycol ether 2 parts modified sodium alkylsulphate 7 parts sodium 2,4-dichloro-6-phenylamino-l ,3,5-
  • the paste is vigorously stirred until homogeneous and printed on nylon 6 yarn at a 100 percent increase over the dry weight on the printed areas.
  • the yarn is treated for 4 minutes at 102 and rinsed with cold water. It is woven into fabric which is exhaustion dyed with a basic blue of the formula O NII-CHr-CII-CHz-N-(CHz):
  • Example 12 A printing paste is made up with 5 parts sodium alginate thickening parts anhydrous phosphate buffer mixture giving a pH value of 8 885 parts water 24 parts octylphenylpentaglycol ether 6 parts modified sodium alkylsulphate 45 parts sodium-2,4-dichloro- 6-phenylamino-l,3,5-
