Abstract

The invention relates to the field of flame retardant treatment of textile materials from a mixture of cellulose hydrate, wool and synthetic fibers and can be used for finishing fabrics in the manufacture of special races and as decorative materials. The invention allows to improve the flame retardant properties of textile materials by treating them with an aqueous composition containing, g / l: methyl phosphonic acid diamide 250-300, ammonium chloride 30-40, urea 50-100, glycine or dimethyl urea 20-40, sulfoside 0.5-1.5 31. 2 table.

The invention relates to fire-retardant processing of textile materials (fabrics, knitted fabrics) from a mixture of cellulose hydrate, wool and synthetic fibers. The resulting fabrics can be used for the manufacture of workwear and as decorative materials.

The purpose of the invention is to improve the protective properties of textile materials,

Example 1 "A scoop-polyester fabric (the ratio of viscose and polyester fibers is 50:50) is impregnated at 50-60 ° C with an aqueous solution of the following composition, g / l:

Methylphosphonic diamide. acid 250

Ammonium chloride 30

Glycazin (mixture

polyethylene glycol esters of pentai and hexamethylolme-

- Lamin.) 20

Urea 50

Sulfoside 310.5

Water Up to 1 l

The impregnated fabric is dried at 95-100 ° C and heat treated for 3 minutes at. After cooling, the fabric is washed with warm, then cold water to pH to remove unreacted products, and finally dried. The flame retardant effect is maintained after 15 washes with neutral washes and 50 chemical cleansing,

Sulfosnd-31 is a composition comprising sodium alkyl benzene sulfate (alkyl, C sp) polyethylated synthetic fatty acid monoethanolamides of the –10 C.1 fraction with ethoxylated 5-6, BA antifoam

Example 2. Viscose-polyester fabric (the ratio of viscose and polyester fibers is 50:50) is impregnated at 50-60 with an aqueous solution of the following composition, g / l:

then the fabric is treated as in example 1.

Example 3. (control). It is carried out analogously to example 2, but instead of sulfosid-31, OP-10 is used.

Example 4 (control). Carried out analogously to example 2, but syntamide-5 was used instead of sulfosid-31.

Example 5. Viscose-polyester fabric (the ratio of viscose and polyester fibers is 50:50) is impregnated at 50-60 ° C with an aqueous solution of the following composition, g / l:

Methylphosphonic acid diamid 300 ammonium hlrid 40 Dimethylolztilen-urea40

then the fabric is treated as in example 1.

Example 6. Viscose-polyester fabric, arg. 674 (the content of viscose and polyester fibers is 67% and 33%, respectively) is treated as in Example 3.

Example 7. Tamme art furniture fabric, 49549 (content of copper-ammonia, wool and nylon fibers, respectively, 59.36 and 5% by weight of the material) is treated as in Example 1.

Example 8 (comparative). Fabric from a mixture of cotton and polyester fibers (the ratio of cotton and polyester fibers is 50:50, polyester fibers are additionally treated with tetrabromobisphenol-A-ethoxylate) are treated with a 30% aqueous solution of alkylphosphonic acid diamide (the content of ammonium chloride in solution is 53% of the mass of diamide alkylphosphonic acid), the impregnated fabric is dried at and subjected to heat treatment for 1 at 171-177 C. After cooling, the fabric is washed with water and finally dried

Example. 9 (comparative). Viscose-polyester fabric (content of viscose and polyester fibers

is 67 and 33%, respectively; treated similarly to example 8.

Example 10 (comparative). The Tamme fabric is treated as in Example 9.

The oxygen index is determined according to GOST 21739-76, the self-burning time according to GOST 11209-72.

The length of the tissue sample to determine the length of the charred area is 25.4 cm.
