Description

 ; I

FIELD OF THE INVENTION The invention relates to the field of finishing, in particular, compositions for filled with anti-irritant cellulose-containing textile materials.

A known aqueous composition is for the hydrophobic finishing of cellulose-containing fabrics, which contains sodium aluminometry with a Si / Al 3 ratio and a pH of 6.0-6.5, and oirconium chloroxide 1.

However, this composition does not provide a sufficiently resistant to repeated washings with a repellent effect. In addition, high cocceitration of sodium aluminomethyl silicate (60 g / l) is required, which is economically disadvantageous.

;

Closest to the invention is

a composition containing sodium alumomethylsiliconate with an SI / AI ratio of 3 and a pH of 6-6.5, zinc or copper acetate and water in the following ratio of components, g / l: sodium alumomers 15-25, zinc or copper acetic acid 5-15, water else 2, which is not effective enough because the treated cellulose fabric absorbs dry contaminants.

. In addition, the composition with copper acetate is colored greenish and the color is transferred to the treated material, which eliminates it when processing white and light colored products. At the same time, it is these products that require a repellent finish.

The purpose of the invention is to demonstrate the effective ™ effect of the composition.

According to the invention, the goal is achieved by the fact that the composition for grains is zoottal-. A nodding finish of cellulosic textile materials containing sodium alumomethylsiliconate with a Si / Al 3 ratio, a water-soluble metal salt and water, a alkaline earth metal salt and a strong inorganic acid, and additionally carboxymetocellulose in the following ratio of components, wt.%;

As the salt of alkaline earth metal Z3 and strong acid, salts of magnesium, alzyl chloride, barium and hydrochloric, nitric or sulfuric acids are used.

The preset composition is prepared as follows: sodium aluminomethyl silicate with a ratio of St / Al 3 (AMCP - 3) before using j peSneitffieM is diluted with water, a solution of carboxymethylcellulose is added and dissolved; alkaline earth metal dormone and strong acid. The bladder is diluted with water at constant volume: the volume required.

It was established experimentally that by introducing soluble alkali earth metal salt into carbon dioxide gas, it reduces the contamination of text materials treated with aluminomethyl C1 sodium sodium (AMGP - 3) ..

The AMCP-3 preparation is sodium aluminum alkyl silicate, the solutions of which are decomposed by acids. Alkyl silanetriols and polyacrylsnlox-25 formed during this process, during the treatment, form an insoluble film on the material surface. In this plant, silicon atoms are chemically bonded through oxygen atoms not only to each other, but also to the surface of the material, squirrel-earth metals form alkylsiliconates of the corresponding water-insoluble metals. When processing cellulose material with the proposed material, it is possible that there are two types with & Zey :; 35 coordination between metal and sandwiches: strong .s1 groups of gels of cellulose and chemical silicon-oxygen-metal. The reaction is carried out at a drying temperature, the npoteo alkyl silicates are fixed on cellulose - -. nom material. At the same time, during the drying, the soluble alkaline earth metal salt undergoes hydrolysis, producing a strong acid that neutralizes the alkalinity of the working solution and converts the filler to an insoluble state. The applied composition during drying forms an unshackled unit, and the material acquires a neutral reaction (checking the pH with vodka, stretching the treated fabric shows 7-7.5). Example 1. An aqueous solution of Elyumomethylsi cionate with an atomic ratio Si / A 3 (AMCP-3), in which carboxymethylcellulose and calcium chloride are introduced, is prepared in the following ratio of components,%:

The fabric finishing is carried out on a double-shaft pluspress with a wringing degree of 80%, temperature of the solution of the plus machine at 20-25 ° C, and then the fabric is dried at 80-100 ° C. The finished fabric is contaminated. The method of contamination consists in mechanically mixing tissue samples with a contaminating mixture in an E-101 bowl mill for 20 minutes at 150 rpm of shaft, the contaminant mixture was DG-10b soot and sodium sulfate in a ratio of 1 : 99.

The effectiveness of a green repellent finish is characterized by the Kubelka-Munk dex (PCM). The growth of contamination is directly proportional to the Kubelk-Munk index.

Samples of the specified fabric after processing the proposed formulations and subsequent contamination are dry-cleaned in accordance with GOST 9733-61 and soap and soda.
