SU13085A1 - The method of obtaining crimson or pink alizarinovye and other mordant colors in print or latch the pluses for unlabeled goods - Google Patents

Description

It is known that in order to obtain, with the help of alizarin, aluminum mordant crimson and pink faults in the press and steamer plugs, it is necessary to add fatty acids or their derivatives, for example, ridinolic acid, so-called sulforidinolic acid, etc. to the composition of lacquer fiber. . It is also known that the introduction of these substances directly into the printing ink or plus is impossible, due to the immediate formation of the lacquer and its loss in an insoluble state already in the ink or nyluse before being applied to the fiber. In this case, the introduction into the paint or plus large quantities of volatile acid, proposed in the literature, but not included in the technique, is also not possible. Favorable results so far have been given only by the use, instead of ricinolic acid or alizarin oil, of various products of ncondensadia with formaldehyde, known as lysaroles. This method, however, increases the cost of production, due to the rather high prices of these drugs.

The proposed method of obtaining alizarin varnishes of usual brightness and juiciness on the fabric, in print or on the padding of the pluses is the introduction of ink or plus containing, except for the thickener, alizarin, dressing,

volatile acid and other common ingredients of unwashed castor oil or other ingredients used to prepare alizarin oil, fatty oil (for example, olive, sunflower, corn oil, etc.), together with any emulsifier that is a fat decomposer when heated, eg. , petroleum sulfonic acids: (reagent "contact), reagent Twitch and other aromatic fatty sulfonic acids, sulfonic acids of the naphthalene series (necal, oranite, leonyl, neomorpine, etc., reagents, naphthalene and naphthol sulfonic acids and others.). It is useful in the presence of a small amount of mineral acid in the paint or plus, which is introduced into them either in the free state or in the form of a salt with a mordant metal (Al) - for example, alum, alumina sulphate, aluminum chloride, aluminum nitrate; etc. As established by experience, the introduction of mineral acid, even in the free state, does not weaken the fabric, since it reacts with organic salts, which are usually present in the dye, moreover, the amount necessary in some cases its very insignificant. Printing ink or a dye bath made up in this way is of considerable value, having been preserved without the formation of varnish for an indefinitely long time. On the contrary, in the steaming, following the packing or padding of the product, introduced into the paint or plus, the splitter separates from the fatty oil the corresponding fatty acid, for example, ricinol, which forms a durable and bright varnish on the fiber with a mordant and alizarin. The proposed method, giving crimson and rose, not inferior in intensity and intensity to ordinary lizarolnymi dyes, and even superior in durability to the latter, is distinguished by its simplicity and cheapness, since the packing is done without pre-maslivation, and the expensive lysarol is taken as a fatty varnish ingredient. not even alizarin oil, but the starting product for them; non-split fatty oil. In addition to the aforementioned ingredients, aldehydes or ketones can also be added to printing ink or plus, which are usually used to prepare lysolols, for example formaldehyde, acetaldehyde, benzaldehyde, furfurol, acetone, as well as formic acid, etc.

Example 1.-According to unlabeled product, a paint is printed consisting of:

starch-tragate thickener .600ch., alizarin SX (or other brand)

207

rodsanite alumina. . . . . 00 h. castor oil. . . . . . 40 hours of sulfuric acid 66 ° Be in 2 parts of water, 1 hour

reagent "contact .8h.

. lactic alumina 30 ° Be,. 30h Calcium Acetate 15 ° Be. 40h acetic acid 6 ° Be .... 50 parts of tin paste ........ 29 hours

1000 hours

After printing and drying, the product is steamed and then subjected to the usual operations for the preparation of an alizarin product.

It goes without saying that instead of the above, a whole other printing ink recipe used in printing with lysarol can be used, and that the amounts of castor oil, sulfuric acid and reagent "contact" can vary somewhat.

Example P.-According to a non-oil product type paint, composed of:

starch traganto zagkis. 510h Alizarin 20 / j-Horo. . . . 100 hours alumina nitrate 15 ° Be. 50 hours alumina acetate 12 ° Be. 40 parts of oxalate tin 20 ° Be. . 65 h. Calcium acetate calcium 15 ° Be. . 50 h.

formic acid 60 hours

lactic acid, 60 h.

sunflower oil, 50 h.

formalin 40 / o or furfural EO / o- 15 h.

1000 hours

Further processing is done in the order indicated in Example 1.

The subject of the patent.

The method of obtaining nunz or pink alizarin and other mordant stains in printing or sealing pluses for unlabeled goods, characterized in that any unsplit fatty oil used for the preparation of printing ink or plus is used for the preparation of izarinovogo oils (for example, castor, sunflower, corn, etc.), and one of the well-known emulsifying fat splitters (for example, arozhaticheskie, fatty-aromatic or petroleum sulfonic acids), with the addition of a small amount of mineral ki slots or sour salt, or without them, and after printing or impregnating and drying, the product is subjected to parsing and other usual further processing.
