Description

The invention relates to the textile industry, in particular to impregnation chemical compositions for restoring lost operational properties to products made of fabrics.

Special cellulose-containing fabrics are used for the production of tents, tents for sheltering equipment, for decorative and finishing products for the interior of hotels and vehicles.

To create the most effective fabrics, combined impregnations are used, for which various impregnating compositions are used.

Known fire-retardant impregnating composition containing an antiseptic - ammonium silicofluoride, ammonium flame retardant sulfate and optionally nitroammofosku and sulfonol (patent RU No. 2147028, C09K 21/04, publ. 27.03.2000).

However, the products obtained have a short service life, rather quickly, after twelve months of operation, lose their operational properties.

Known fire-bio-moisture-proofing impregnating composition containing an antiseptic - ammonium silicofluoride, flame retardant - diammonium phosphate, aluminosilicate filler and casein glue (copyright certificate SU No. 279020, C09K 21/04, publ. 21.08.1970).

However, in conditions of high humidity, fire protection of products is unsatisfactory.

A known method of light biostoy and waterproof decoration of fabrics based on flax fiber by impregnation with aqueous solutions containing an organic tanning agent with additives, copper sulfate, sodium sulfide, soap-paraffin emulsion, aluminum or zirconium acetate (copyright certificate SU No. 1819929, D06M 15/263 ; 13/02, publ. 03/27/2000).

As practice shows, under operating conditions, products treated with known compounds lose their performance properties.

To restore the lost properties, re-impregnating chemical compositions are used.

Known drug for restoring the bio-water-resistant properties of products from cellulose-containing fabrics for special purposes, including styrene butadiene rubber in the form of 50% latex, a coloring matter with fungicidal properties 4, 5, 6 - trichlorobenzoxazole - 2; alkaline agent and water (patent RU No. 2091528, D06M 15/692, publ. 09/27/1997).

The product processed by a well-known preparation retains special properties for 24 months of operation, while it significantly loses strength characteristics and has a narrow range of protective properties.

The closest in essence is the known composition for the impregnation of products from cellulose-containing fabrics, including a binder - polystyrene, a solvent - dichloroethane, a dye (biocide) - trilane and an organophosphorus flame retardant - floman (Kocharov S.A. et al. Development of a method for restoring the operational properties of fabrics for shelters. Collection of scientific works TsNIILKA. - M., - TSNIITE LEGPROM, 1991, p.138).

The known composition gives the products fire-bio-waterproof properties that are stored for 12 months of operation, they have a low recovery period and the processing process requires special equipment.

The objective of the present invention is to provide the most effective drug for restoring a set of necessary properties of products lost during operation.

The technical result is to improve the efficiency of the finish by increasing the strength and aesthetic characteristics and ensure a stable effect of fire protection to wet treatments.

This technical result is achieved by the fact that the proposed preparation for restoring the operational properties of products from fabrics, including a binder, fire retardant, a dye with fungicidal properties and a solvent, according to the invention additionally contains triethanolamine and acetic acid, and as a binder it contains gelatin or casein, or carpentry or glue, as a flame retardant - borate of zinc, and / or magnesium, and / or tin and chlorine paraffin with a chlorine content of at least 62%; as a coloring matter with fungicidal properties, a metal soap based on stearate or oleate of metals of variable valency selected from the group comprising aluminum, zirconium, zinc, copper, iron, as a solvent, water, in the following ratio, wt.%:

Binder 6-10 Borate of zinc and / or magnesium and / or tin 10-15 Chlorine paraffin not containing chlorine less than 62% 20-35 Coloring agent with fungicidal properties 4-10 Triethanolamine 4-7 Acetic acid 8-10 Water rest

Known compositions for impregnation contain polymer binders, which are used as synthetic polymers, rubbers, latexes, synthetic resins. These substances are quite expensive and currently their production base is limited, and the process of impregnation requires special conditions and protective equipment for workers.

In the proposed preparation, a protein of animal origin is introduced as a binder - gelatin, casein, carpentry and coarse glue.

The introduction of metal compounds of zinc, magnesium, tin with boron oxides, namely zinc borate, and / or magnesium, and / or tin in combination with chloroparaffin with a chlorine content of at least 62% provides high fire resistance, the product does not burn.

One of the main requirements for fabrics is to increase their operational reliability, i.e. ability to maintain their protective properties during operation. Strength index also acts as one of the criteria for the durability of operational properties.

The main disadvantage of fabrics is a short service life, expressed not only in the loss of protective properties, but also in a change in the appearance of the fabric. During operation, the fabric acquires a dull shade, the intensity and brightness of the color changes, strength decreases, and protective properties are lost.

As a result of applying the drug to the fabric, strong bonds are formed, the fabric turns into a dense elastic composite with high strength and aesthetic characteristics. Products made from these fabrics retain high strength and rich color for a life of more than 24 months, high water resistance and fire resistance to wet treatments.

In the preparation according to the invention, each component is known, but their combination and the proposed quantitative ratios give new unexpected results that are not inherent in the signs of their separate administration. The claimed qualitative and quantitative composition of the drug ensures the achievement of a technical result, and their change in the direction of decrease or increase does not lead to a high result.

The invention is illustrated by the following examples.

The drug to restore the operational properties of products from special fabrics before application to the product is pre-diluted with two, three parts of warm water. The resulting working preparation in the workplace is applied to the product with a brush or a paint roller, followed by drying.

The specific composition of the drug and operational characteristics are presented in table. 1 and 2. Table 1 shows the specific composition of the drug according to the examples, example 1 is comparative, examples 2-5 are according to the invention.

Table 2 presents the operational properties of fabrics that have undergone a three-year operation at a stand in the Moscow region and have lost their operational properties, impregnated with the proposed drug.

As can be seen from table 2, the fabrics impregnated with the preparation according to the invention have fire-bio-waterproof properties, namely, they have restored their operational properties, so the fire resistance of the fabric after 5 washes in cold water does not change, the fabric does not burn and does not smolder, the water resistance is up to 250 mm of water. st., fungicide, fungus resistance equal to 0 points, while the strength of the fabric art. 11266 increases after impregnation to 78.6 kgf instead of 65.0 kgf and up to 58.1 kgf instead of 47.0 kgf, art. 3122.

Thus, an effective preparation has been developed for restoring the fire-bio-waterproof properties of products made from fabrics lost during operation, which allows it to be widely used without additional conditions and special equipment.

The use of the proposed drug increases and provides products with a stable fire protection effect to wet treatments, betrays increased strength and rich color, which is very important for products that operate in natural weather conditions.
