(57) Abstract:

Usage: in the textile finishing industry. The inventive Linklaters fabric, such as code 11201, containing the basis of cotton and flax duck, treated at 80 - 85°C for 1.0 to 1.5 min in an aqueous solution of poly(meth) acrylic acid or its sodium or potassium salt and soda ash 10 - 25 g/l and dried to a moisture content of 20 - 30% . Impregnated at 60 - 85°C for 1.0 to 1.5 min in an aqueous solution of sulfuric acid copper 40 - 45 g/l maturing in the wet state at room temperature 15 to 30 minutes and rinse. Then treated at 95 - 100°C for 1.0 to 1.5 min in an aqueous solution of sodium sulphide 5 - 7 g/l and dried to a moisture content of 20 - 30%. Treated at 75 - 80°C for 1.0 to 1.5 minutes of Soap and paraffin emulsion with a concentration of dry substance 75 - 80 g/l and alkalinity in the calculation of the caustic sodium 0.6 - 0.8 g/l and dried to a moisture content of 20 - 30%. Soaked at room temperature in an aqueous solution of the acetate of aluminum or zirconium concentration in the calculation of the alumina or Zirconia 15 - 20 g/l for 1.0 to 1.5 min and dried to moisture content of 6%. The fabric is dyed in a deep rich color "khaki" and keep the Oia within 120 h in the chamber of artificial aging and 2 3 points after irradiation. The loss of strength of the fabric after UV irradiation for 120 h of 35 to 38%. table 1.

The invention relates to chemical technology of textile materials, to the production of colored cellulose-containing fabrics, namely to the way light is biostable and waterproof finishing of fabrics, containing linen and/or cotton fiber.

A method of obtaining colored light-biotopami flax-containing tissues, including the processing of fabrics with an aqueous solution containing 15 to 23 g/l of oak extract, 20-40 g/l of water-repellent (soap, stearic acid), drying to a moisture content of 20-30%, the impregnation with an aqueous solution containing 40-50 g/l of copper sulfate, 18-20 g/l of potassium bichromate, 15-20 g/l of acetate of aluminum or zirconium in terms of metal oxide, 0.5-1.0 g/l of acetic acid at 60 to 65aboutWith, maturing within 15-30 min, treatment with an aqueous solution containing 5,0-7,0 g/l sodium sulfur, and optionally containing 20-40 g/l of water-repellent, with 95-100aboutWith, rinsing and drying the fabric to a moisture content of 6-8% [1].

The disadvantage of this method is the low biopersistence and wastewater pollution by toxic compounds.

The closest t is Anna by sequential treatment with an aqueous solution, containing 15-25 g/l of oak extract, at 80-85aboutWith the drying up 20-30% humidity tissue; impregnation with an aqueous solution containing 40-45 g/l of copper sulfate and 18-20 g/l of potassium bichromate, when 60-85aboutWith and aging in the compensator within 15-30 min, treatment with an aqueous solution containing 5-7 g/l sodium sulphide, flushing hot and cold water, drying the fabric to a moisture content of 20-30%, processing soap-paraffin emulsion with a concentration of 75-80 g/l and alkalinity 0.6-0.8 g/l in the calculation of the caustic sodium at 75-80aboutFrom under the dryer until the moisture content of the fabric up to 20-30% , re-treatment soap-paraffin emulsion, impregnation with an aqueous solution of acetate of aluminum or zirconium concentration of 15-20 g/l calculated on aluminum oxide or zirconium and 0.5-1.0 g/l of acetic acid at 20-25aboutAnd the final drying of the fabric to a moisture content of 6-8% [2].

The main disadvantage of this method is that the resulting fabrics have low funginertness. Tanning tissues according to the method provide a natural tanning agent - oak extract, which is a good nutrient medium for the development and growth of microorganisms. Use in finishing as a light stabilizer tissues dvuhromovokislyj potassium leads to zagryazneniemenee medical-Toxicological indicators and as a result, environmental pollution.

The purpose of the invention is improving the efficiency of finishes and improvement of environmental safety of the process.
