METHOD FOR PRODUCING ABSORBABL SURGICAL SUTURE MATERIAL BASED ON MONOCARBOXYCELLULOSE ABSTRACT OF THE DISCLOSURE The method consists in that cellulose threads are first treated with nitrogen oxides, then for 0.5 to 2.0 hours treated with a 0.5-2.0 percent solution of a salt of a transition metal with a coordination number not less than 4 in a suitable compound, and after this for 0.5 to 2.0 hours treated with a 1.0-2.0 percent solution of a polydentate complexing agent in a suitable solvent. The proposed method allows producing a suture mate- rial with a higher mechanical strength and with a colour which is in contrast with the background of blood and wound tissues.
