Application October 25, 1940, Serial No. 362,789
This invention relates to the printing of acid general by incorporating certain assistants into the printing pastes which contain acid and direct,
colors. These assistants may be present in the proportion of about 3 to about 20 parts of assistant to 3 parts of color and the color may comprise about 1% to about 8% of the paste, the remainder of the paste being constituents which make the composition adaptable for printing with etched rollers or blocks. Suchremaining constituents are materials such as textile gums, .water or any other desired constituent commonly used in textile pastes. The assistants are hydrotropic agents, being alkali-metal salts of a class of compounds consisting of aliphatic sulfuric and sulfonic' acids having 3 to 12 carbon atoms, benzyl thioglycollic acid, alkyl thioglycollic acids in which alkyl has 1 to 12- carbons, aryl sulfonic .acids of the benzene and naphthalene series which may be nuclearly substituted once to four times by alkyl having 1 to 8 carbons, halogen, hydroxy or nitro, and mono-esters of the group consisting of the naphthalene dicarboxylic acids and dicarboxylic acids containing not more than 8 carbons of the group consisting of phthalic,
thereof. Parts are expressed in'parts by weight unless otherwise noted.
- Example I A viscose process rayon fabric was printed with l a paste consisting of Parts by weight Direct color dyestuiT-C. I. #814 3.0
Sodium para toluene sulfonate"; 10.0 Water 17.0 v Textile gum 70.0
The print was dried, steamed 45 minutes,
soaped lightly (3-5 minutes at 110-120 F.), rinsed and dried. The print was a bright yellow shade. The print was noticeably stronger and faster to soaping than a print made on the same fabric with a similar printing paste which did not contain sodium para toluene sulfonate.
Example II A viscose process rayon fabric was printed with a paste consisting of The printed rayon was dried aged 45 minutes by steaming, soaped lightly, rinsed and dried. The printing was an even brilliant red design. It was stronger and faster to soaping than one made on the same kind of fabric with a similar printing paste which did not contain sodium N-butyl v sulfate.
Example III Viscose process rayon fabric was printed with a paste consisting of Parts by weight Direct color dyestuiTC. I. #319 3.0
Sodium benzyl thioglycolate 7.5
Water 19.5
Textile gum 70.0
The print was steamed, soaped and finished as described in Example I. The print was a brilliant violet design which was stronger and faster to soaping than a print made in the same way on the same kind of fabric with a similar paste except that the latter paste did not contain sodium benzyl thioglycolate.
Any acid color or any direct color can be used as the color constituent in the new pastes:
with similar improvement in result. As illustrations of such dyestuffs the following are mentioned: direct color dyestuffs Color Index numbers 813, 561, 581, 812, 620, 816 and acid color dyestuffs Color Index numbers 307, 289, 666, 670, i088 and 1080. As representative of other soluble salts of the described class of assistants which can be used with any of the direct or acid colorsmethyl adipic, succinic, methyl succinic, dimethyl succinic, chlor malonic, tartaric and suberic acids. The preferred assistants are the alkali-metal salts of the indicated alkyl sulfuric acids, the alkyland benzyl-thioglycollic acids and monoesters of the dicarboxylic acids. In the foregoing examples the ratio of dyestu to assistant in the paste is 3 to 10 by weight, but other proportions can be used. This proportion can be varied with 3 parts of color from about 3 parts to about 20 parts of assistant. The proportion of water textile gum and other constituents can be varied within any desired limits which will enable the paste to be used for the purpose of printing fabrics by the use of etched rollers and like appliances. The proportion of textile gum and water can be varied within any limits which will give the printing paste a suitable viscosity for printing. Any textile gum suitable for this purpose can be used, such as gum tragacanth, starch, locust bean gum, gum karaya, gum arabic,'dextrin, agar, vegetable colloid and various mixtures of such materials. More or less of the thickening agent will be required in order that the printing paste will have a suitable viscosity to operate satisfactorily on the etched roller or other printing device. The proportion can be widely varied and determined by experiment according to various circumstances, such as the characteristics of the printingmember and the material upon which the prints are to be disposed.
From the foregoing disclosure it will be recognized that the invention is susceptible of modification without departing from the spirit and scope thereof and it is to be understood that the invention is not restricted to the specific illustra- 5 tions thereof herein set forth.
