The finish obtained by the method according to the invention causes the specific electrical resistance of the modified fiber to The 10 washes increase by one or two rows of size, ie from 10 "cm to 10". cm, which proves that the obtained effect is more resistant to washing than in the known method. The following aromatic acids are used for the pretreatment: benzoic, o, m, p-bromo benzoic, o, m, p-chlorobenzoic, o, m 1 p - iodobenzoic, o, mi p-hydroxybenzoic, o, mi p-aminobenzoic, o, mi p-methoxybenzoic, o, and p-acetobenzoic, o, and p-acetobenzoic, mi p-acetylaminobenzoic, acetylsalicylic, o, mi p-aminobenzoic, o, mi p-benzoylbenzoic, oi p-benzylbenzoic, terephthalic, o, mi p-toluic, 2,3-dihydroxy-2,4-dihydroxy-2,5-dihydroxy, 3,4-dihydroxy and 3,5-dihydroxybenzoic, 2,3-dimethyl, -2,4-dimethyl, 2f 5-dimethyl, 2,6-dimethyl, 3,4-dimethyl and 3,5-dimethylbenzoic. Example I. 105 / 4.4 dtex polyamide fiber was treated with water solution of salicylic acid with a concentration of 30% in relation to the weight of the fiber at 50 ° C for two hours, The fiber thus prepared was covered with an electrically conductive layer, i.e. o a solution containing a copper compound and a reducing agent with a reactive atom 2 133 956; sulfur. The specific electrical resistance was 8.3 • '0 and • cm, and after 10 washes it was 9.1 • 103 • cm. Example II. Polyamide continuous silk was immersed in a solution of terephthalic acid at a concentration of 0.5% by weight of the fiber and heated at 120 ° C for 1 hour. The fiber was then rinsed in water and treated further as in example I. The electrical specific resistance of the silk was 3? 10 £ 2 • cm, after 10 washes 2.5 • 10 §l • cm. Example III. The polyamide fabric was treated in a solution of terephthalic acid with a concentration of 10% in relation to the weight of the fabric, at 100 ° C, for 0.5 hours. After thorough rinsing, the product was subjected to the following bath at 24 ° C: 0.1 mole / l of copper nitrilotriacetic acid complex 100 g / l of sodium thiosulphate 100 g / l of urea 5 g / l of ammonium acetate After drying, the watered fabric was steamed at 160 ° C for 5 minutes. The fabric resistance after modification is 2.1 × 10 µffi after 10 washes 9 × 10 µs. Example IV. The 1.5 dtex polyacrylonitrile fiber was treated in a benzoic acid solution with a concentration of 20% in relation to the weight of the fiber, at a temperature of 50 ° C for 1 hour. An electrically conductive layer was applied to the fiber prepared in this way as in Example I. The specific electrical resistance after the process was 1.5 × 10 cm, and after 10 washes it was 5.8 × 10 × 1 cm. Patent claims 1.
