Description

UNITED STATES PATENT-OFFICE.
DAVID JULIAN BLOCK, OF CHICAGO, ILLINOIS, ASSIGNOR T0 SUNIBEAM CHEMICAL COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS, AND-CHARLE C. HUFFMAN, OF CHICAGO, ILLINOIS.
DYE-SOAP AND MORDANT.
80 Drawing.
To all whom it may concern Be it known that I, DAVID JULIAN Bnoox, a citizen of the UnitedStates, and resident of Chicago, in the county of Cook and State of Illinois, have discovered a certain new and useful Dye-Soap and Mor(' at, of which the following is a specification.
My invention relates to dye soaps and partlcularly to a novel combination of a dye soap and mordant.
' ne of the principal objects of the invention is to provide a composition in which a greater range of dye may be employed in order to securee ually satisfactory results.
In the making 0 a dye soap it has been found that in order to produce a universal dye soap only a certain limited number of dyes may be used. The difiiculty has been in causing the dyes-of other than a certain limited number to adhere to the fabrics without the use of a mordant.
The present invention contemplates the addition of the mordant to the material and to mechanically mix the same therewith.- This is not generally practical where the dye soap is marketed in cake form for the reason that the mordant is likely to cause precipitation of the dye or oxidization or alteration of the dye stuff. I have found, however, that by flaking or otherwise finely dividing the product the mordant added thereto will not injuriously aflect the substance and dyestuffs may be employed which were not heretofore considered practical for use in dyesoaps.
By the word mordant as used herein I refer to any substance which may be used in connection with coloring matter, either as a preliminary treatment of the fabric prior to the application of the dye, or color; or any after treatment intended to improve, or 0th erwise alter, the tone, shade, tint, evenness or uniformity of the dyeing; its fastness to light, heat, washing, topping, perspiration, or chemical action; or tending to "affect the solubility, or the equalizing properties of the dye.
In making a dye soap in accordance with my invention the material may be prepared in the usual manner by suitabl mixing a vegetable oil or other saponifiab e substance with the necessary quantity of sodium hydroxid or other saponifying agent, to this may be added the dye stuff in solution. If
Specification of Letters Patent.
Application filed April 21,
Patented Dec. 14, 1920. 1919. Serial No. 291,115.
the mordant is to be actually combined with the soap mass it will be added thereto in the crutcher, after which the material is immed ately flaked or otherwise finely divided in order to assure solubility The reason why the mordant does not affect the dye stuff when the material is in the form of flakes is not entirely understood but it is belleved to be for the reason that the flaking ofthe material results in the dissipation of substantially all the uncombined water and of yellow, tan, and brown by adding to soap flakes containing as a dye, the sodium salt of diphenyldiazobi-salicylic acid (chrysamin (Jr) a mordant flake containing about 20% Glaubers salt, and 1% soda ash. These may be directly combined with the soap flake during the process of saponification, or may be'added after the soap is formed by crutching or mechanically working the salts into the soap; The foregoing proportions are productive of light shades; for darker colors I double the quantity of mordant material added; this treatment is roductive of brilliant yellows. For tans use the same dye flake and mordant flake, but add to this mixture a flake containing in mechanical admixture, a wei ht of copper sulfate equivalent to the weig t of dye used.
' As a practical example of after treatment I add to dye flakes containing the sodium salt of dimethoxy-diphenyldiazo-naphtholdisulfo'nic-azo-di metatoluenediamin (direct blue black) as a dye, a soap flake carrying in benzene-azo-meta-phenylene-diamin (chrysoidin) which makes the dye alike applicable to silk, WOOl, or cotton. I add soda ash to the mordant flake for use with the soda salt of ditolyldiazo-dinaphthionic acid (benzopurpurin 4 B) to secure fast reds on cotton; tannin and tartar emetic to the zinc double chlorid of tetramethyl di paraamido triphenyl-carbinol (malachite green) to render the dye universally applicable to silk, wool, jute, leather and-cotton.
It will be understood that the product herein claimed may be produced by the use of materials other than those herein s ecified and may be marketed in a condition other than the particular condition specified. Many mordants other than those specified and many (1 es different from those mentionedmay e'employed with satisfactory results and I do not wish to be limited other than as indicated in the appended claims.
I claim:
1. A dye soap in the form of-flakes and a mordant mixed with the flakes, substantially as described. I d
2. A dye soap in the form of particles and a mordant in substantially -the same form combined and mechanically mixed therewith, substantially as described.
' Signed-at. Chicago, Illinois, this 14th day of April, 1919. I
