vThis invention relates to dye compositions sium or ammonium. acid sulphate or; acid' and particularly to stable dry powder water phosphate, together with an agentwhichoflisoluble compositions for household use in Fsets theihygrosco'pic properties'of the acid dyeing silk goods V sulphate or acidiphosphate. Such'an agent The particular object of this invention is lis starch which acts by coating the particles .5 to provide a dye composition which will give of hygroscopiclacid salts and" thus, protects improved brilliancy, fastness and finish to them from the atmospheric moisture, as well I thegoods, and at the same time havingall as. absorbing atmospheric ;,1noisture, and of the necessary characteristics of a practithereby preventing caking of the? dry dye cable household dye. U v powder,composition ,Inlconnection with Vhile silk dyeing-compositions of this suchcoinposition;aleveling or'filling mateclass have heretofore been used wherein an rial; is generally used, suchas s'odiumsulacid dye is coinbinedwith an acid salt-capable phate. I V i j f of hydrolyzing in water to release free acid I have efurtherr found that a very desirable for combinationwith thefdye, it has hereto improvedaction of thedyeing agent is ob 5 fore been considered impracticable to use subtained to givethe silk'fiber, more luster and a stances giving a relatively high hydrogenr better body and'jfinish if a water, soluble ion concentration insolution, such as di-basic V colloidal material is included in the composihydrogen-alkali metal salts of the highly eon; ,Such a'material is gelatin whichl can ionized-mineral acids. The practice heretoadd as a dry powderwith' the other ingredifore has been to use as an acidifying agent ciitspbut whicli I preferablyaddina novel 1 dry non-hygroscopic acids such as tartaric, manner in the form offa, capsu'le'which en- 7 fumaric' and maleic acids,' and [also non- "closes theintirepowdera Whenthrown into hygroscopic salts such as sodium acid the ,h'ot fvvater usedjjor'dyeing the gelatin fluoride. I have now discovered that salts capsule immediatelyzdi'ssolves and, with" its such as the acid sulphates or acid phosphates contents, gives the correct proportions toobof sodium, potassium andammonium when tain; the desired efiect. "Thisis an improvedissolved in water produce a much higher nlent gover the-customary method of using hydrogen-ion concentration than the acids "household dyes by measures, as j ordinary and sodium acid fluoride above mentioned, household methodsare inaccurate and lead 5 a 7 An objection to the use of acid sulphates and to erratic results; By the use of dye comacid phosphates which give a very high positions capsules for household dyeing hydrogen-ion concentration is their hygro- {ofall fabrics and textiles more reliable and 'scopic'ity, which causes a dry powder acid betterresultsare obtained,
, dye composition to aggloin'erate or cake, or ""lna s'much'as thefinerarticles of feminine 13 even to partly deliquesce, Vw hich ,not only ;app'a rel"are the articles usually-dyed by the interferes with the keeping qualities of the class' fof dye {to which this invention specomposition in a store, but afiectsthe solu cifically relates, and as the Operation ofdyebility, and causes the dyeing'to be weak as ing isin itself somewhat unattractiver l; fur- 9 well as speckled or uneven. Ihave' found ther introduce-into thecoinposition' a ;per
that a dye composition not subj ect to the forc fuming agent to convey to the {dyed garments going objections-can be'produced'by coinbina pleasing and'refreshing odor, and in so ing an acid dye incapable of being predoing take-advantage of the natural'property ipitated by free acid of a'levelingor filling of starch forabsorbing and retaining essenagent, with hi hly ionizable sodium, potastial oils and other perfuming materials. Thaistarch consequently serves as a carrier for the introduction of such quantity of perfume as will impart a pleasant and agreeable odor to the product, without affecting absorption of the dye by the goods and w'thout causing any change in the shade desired.
A suitable composition is:
Parts by weight Soluble acid or azo dye, such as acid violet 1013 or acid violet 4BM to 8 Sodium sulphate to 200 Starch 5 to 7 5 Sodium acid sulphate to 25 Gelatin to 10 Oil of rose or other perfume to 2 If ammonium or potassium acid sulphate or acid phosphate are used instead of sodium acid sulphate herein referred to, a somewhat greater quantity will be required.
The first tour materials may be mixed dry in a suitable mixing apparatus, and the perfirst be mixed with the hygroscopic salt, to
coat same, and then the other ingredients added to this mixture. Ten to twenty grams of the above composition to one gallon of hot water (more or less according to the shade desired) immersed for three minutes, and then rinsed thoroughly, will give a fast shade and impart an improved luster, brilliancy and finish to the goods. lVhile the perfume may be omitted, itnevertheless has a pleasing and beneficial effect, and where used has been found to be unexpectedly lasting.
lVhile I have particularly described my invention with reference to silk dyeing, which usually employs acid or azo dyes incapable of being precipitated by the acid highly ion- ,izable salts specified, the invention in its broader aspects is applicable to other well known dry powder water soluble dyes, such as basic dyes, and for dyeing other materials such as cotton, wool, rayon, linen, etc. Where I specify starch, I means the term to be con: strued broadly to cover various materials having the common properties in dry powder form of coating a. hygroscopic salt, making a colloidal solution in water, and sufficiently absorbent as to absorb and hold a perfuming agent. I thereforedo not restrict the scope of the invention except as required by the appended claims.
The invention claimed is: a
l. A stable dry compositionfor silk dyeing comprising an acid dye, a hygroscopic add salt capable of hydrolyzing in water to release free acid for combination with the dye, and an anti-hydroscopic agent coating the particles of hydroscopic acid salt.
2. A stable composition for silk dyeing comprising an acid dye, a hygroscopic acid salt capable of hydrolyzing in Water to re lease free acid for combination with the dye, and starch coating the particles of hydro scopic acid salt.
3. A composition for silk dyeing comprising an acid dye, an acid sulphate incapable of precipitating an acid or azo dye, and starch.
4. A composition for silk dyeing comprising an acid dye, an acid phosphate incapable of precipitating an acid or azo dye, and starch.
