A METHOD FOR BIO-STABLE, LIGHT-RESISTANT AND WATER-PROOF FINISHING OF FABRICS CONTAINING FLAX AND/OR COTTON FIBRE

摘要

Use: in the textile finishing industry. SUMMARY OF THE INVENTION: hlopkosoderzheschuyu flax or fabric impregnated with an aqueous solution of polyacrylic acid or lolimetakrilovoy or their potassium or sodium salts of 1-5 g / l at 75-85 & amp; deg; C. Dried to a moisture content of 20-30%. Is impregnated with an aqueous solution of copper sulfate 40-45 g / l and a sulphate or ferric chloride at 80-85 & amp; deg; C for 1-1.5 minutes. Be aged 15-30 min and washed. Treated with soap and paraffin emulsion 75-80 g / l, calculated on the dry matter and alkalinity 0.6-0.8 g / l in terms of sodium hydroxide at 75-80 & amp; deg; C for 1-1.5 minutes. Dried to a moisture content of 20 to 30%. Atse-- impregnated with an aqueous solution of zirconium or aluminum acetate 15-20 g / l in terms of zirconium oxide or alumina. Indicators of quality fabric: water-resistant nature in accordance with GOST 3816-81. 21-25 cm, the loss of strength after the test in an artificial light chamber IP 100 h 40-49%, bush GOST 9.060-73 91-95%, fouling fungi GOST 9.048-75: Starting points 1-2, after the test chamber artificial light 2-3 points. Table 1. The purpose of the invention - increase the efficiency of finishing. This aim is achieved with a method light-, biostability and waterproof finish fabrics containing linseed and / or cotton fibers, treating them with an aqueous (A to C at about SP with SP
