Definitions

  • the present invention relates to a process of dyeing textile fibers by slop-padding and printing.
  • the printingand slop-padding of textile fibers with the esters of the leuco-compounds of vat dyestuffs is performed by printing or slop-padding the fibers in the usual manner with a printing paste or in a bath respectivel containing a leuco-ester of said vat dyestufi s, an agent for saponifying the ester, an oxidizing agent, such as sodium chlorate, an oxidizing catalyst, such as v the ammonium salt of the vanadinic or tungstic-acid and, in the case of printing, thickening agent, for example starch, gum or tragacanth.
  • vat dyestuffs such as indigo, indigoid dyestuifs, anthraquinone dyestuffs andothers
  • the fiber which has been printed or slop-padded in the usual manner is dried, then the dyestuffs is developed by saponification of the ester and oxidation of the leuco- :omp ound,.finally thefiber is rinsed and dried.
  • saponifyin'g agents that means as agents yieldin hydrogen ions by the ac- ,tion of steam, c orides, esters and anhyvmay be varied within drides, of aliphatic and aromatici sulfom'c acids and of aromatic carboxylic acids, the sulfo-chlorides of the aromatic series being the most valuable'saponifying agents.
  • the quantity of the ne'wsaponifying agents used the widest limits; enerally we add to the printing paste or ath about 1 to about 8% or more calculated on the amount of the printing paste or bath; but,.
  • the saponifying agents used in our invention are insoluble in water, they are added to the paste or bath dissolved-in a suitable organic solvent, such as diethylenedioxide, acetone, alcohol, d -(B- hydroxyethyl) -thioether, enerally in a conylester of naphthalene-2-sulfonic acid naphthalene-1.6-disulfochloride and the esters of the naphthalene-1.6-disulfonic acid, naphthalene-2l7-disulfochloride, and the esters of the naphthalene-2.7-disulfonic acid, naphthalene 1.3.6 trisulfochloride.
  • a suitable organic solvent such as diethylenedioxide, acetone, alcohol, d -(B- hydroxyethyl) -thioether
  • the"slop padding process is an equivalent of the printm process.
  • an oxidizing agent an oxidizing catalyst, a thickening agent and a saponifymg agent of the group consisting of the chlorides, esters and anhydrides of aliphatic sulfonic acids and of sulfonic and carboxylic acids of the benzene and naphthalene series, drying the fibers, steaming, washing and drying the 2.
  • the lprocess which comprises printing fibers wit a printing paste containing an ester of a'leuco-compound of a vat dyestufi, an oxidizing agent, an oxidizing catalyst, a th ckening agent and an aromatic sulfochloride of the benzene and naphthalene ser es, the fibers, steaming, washing and drlyl'mg't e same.

Ito 8% (calculated on the weight of the printing paste) of naphthalene-1.6-disulfochloride, drying the fibers, steaming, washing and drying the same;
  • the process which comprises printing fibers with a printing paste containing an ester of a leuco-compound of a vat dyestufi, an oxidizing agent, an oxidizing catalyst, a thickening agent and about 1,25% (calculated on the weight of the printing paste) of a sa'ponifying agent of the group consisting of the chlorides, esters and anhydrides of aliphatic sulfonic acids and of sulfonic and carboxylic acids of the benzene and naphthalene series, drying the fibers, steaming, washing and drying the same.
