Description
N Drawing.
To all whom it may concern Be it known that I, IIARTLEY FLETCHER, a subject of the King of Great Britain, and resident of Thaon-les-Vosges, France, have invented new Improvements in the Dyeing of Fabrics and Fibers with Anilin-Black by ()xidization in the Air, which are fully set forth in the following specification. The present invention relates to anilin blackdyeing, and more particularly to anilin dyeing as practised according to the process disclosed in my prior Letters Patent, Number 1,102,898, granted July 7, 1914. The chief feature of the patented pro ess is the subjection of the fabrics or fibers to the action of a dye bath which consists of anilin, paraphenylene-diamin, hydrochloric acid, formic acid, copper-sulfate and sodium bisulfite in certain specified proportions, as may be ascertained from 'said patent, the material to be dyed, after having been treated with such bath, being successively dried and subiected to a finishing treatment. It is the object of this invention to improve the patented bath by reducing the quantity of the paraphenylene-dianun and its solvent, formic acid, and of the sodium bisulfite, and by increasing the quantity of ,the copper-salts, as a result of which, a fast black may be obtained without requiring any finishing treatment of the material. although such treatment carried out, in order to render the color absolutely incapable of turning green, and to insure all portions of the material being sufiiciently oxidized.-
According to the present invention, the improved dye bath is composed of the following ingredients in substantially the pro portions stated. vizr- Anilin Para phenylene-d I am 1 n grams. 3 gra m s.
45 Iydrochloric acid 35 grams. 90% formic acid Sgrams. Copper sullite 9 grams.
opper acetate 3grams. ry sodium bisulfite Qgrams.
5o Vater to make up 1 liter.
As will be seen from a comparison of the above formula with that disclosed in the patent, to which latter reference may be had for a complete understanding of the process. the present bath contains 3 grams less of a Specification of Letters Patent. Application filed August 20, 1913.
may, if desired, be-
Patented Dec. 1, 1914. Serial No. 785.769. paraphenylene-diamin, 5
mic acid, and 1 gram lite, but conta1ns3 grams less of forless of sodium bisulgrams more of copper sulfate, and, in addition, 3 grams of copper acetate, which has no counterpart in the earlier bath. However, the quantityof paraphenylene-diamin contained in the present bath still greatly exceeds that included in the ordinary anilin black dye bath, while the material undergoing treatment, after having been impregnated by repeated immersions in the bath, is dried in any suitable manner, as, for instance, by being suspended in a drying room for 48 hours, or left in a map for the same of time, during which period they are repeatedly aerated, to produce oxidation in the air. Excellent results are even obtained by material to oxidize in the air ours, and even for 12 hours.
As previously stated, the employment of tie improved bath renders a finishing treatment unnecessary, although such treatment may be followed when it is desired to comp etely avoid all danger of the color turninsure complete oxidation. is made use of, it is deemed preferable to carry it out after chromation, the material being passed through a bath composed of anilin oil, or its homologues or analogues, instead of through a bath composed of an anilin salt dissolved its homologues, as
he proportion of anilin oil may extend, if desired. to saturation.
claim 1. The herein-described bath for dyeing textile material which-consists of 45 grains of anilin, 3 grams of paraphcnylene-dianiin, 85 grams of hydrochloric acid. 5 grams of 00% formic acid, 12 grams of copper salts. '2 grams of dry sodium bisulfitc. and water to make up 1 liter. 7
2. The herein-described bath for dyeing textile material which consists of 45 grams for only 24 causing the 111 the patented process. I
of anilin, 3 grams of paraphenyiene-diamin, 35 grams of hydrochloric acid, 5 grams of 90% iormic acid, 12 grams of copper salts, including copper acetate, 2 grams 0 dry sodium bisu1fite, and Water to make up 1 liter.
In testimony whereof I have signed this specification in the prsence of two subscribing Witnesses.
