Direct azo dyes and their effect on self-purification of water

Direct azo dyes and their effect on self-purification of water. Timofeeva, S. S.; Kashina, N. F.; Shevernovskaya, O. A. (Irk. Gos. Univ., Irkutsk, USSR). Deposited Doc., VINITI 6831-83, 109 pp. Avail. VINITI (Russian) 1983. DOCUMENT TYPE: Report CA Section: 61 (Water) Section cross-reference(s): 41 All azo dyes studied, i.e., Direct Fast Bordeaux [94362-47-7], Direst Fast Orange 2 Zh [39363-31-0], Direct Dark Green [3626-28-6], Nigrosine Water Sol. (I) [8005-03-6], Direct Fast Brilliant Blue [6527-70-4], Direct Violet S [38493-85-5], Direct Brown KKh (II) [2429-82-5], Direct Black Z [1937-37-7], Direct Black 4K (III) [2429-83-6], and Direct Diazo Black S, [2429-73-4] had no substantial effect on the O conditions, pH, the development of saprophites, and the total count of microorganisms in the water when present in concns. of 0.001 mg/L. At higher concns., e.g., 0.1, 1.0, and 5.0 mg/L, the dyes cause more significant changes in water quality indexes and impact water self purifn. The max permissible concns. that do not effect self purifn. processes are 0.01 mg/L for I, II, and III, and 0.001 mg/L for the rest of the dyes.

Dyeing absorbent microbiocidal fabric for surgical goods

Dyeing absorbent microbiocidal fabric for surgical goods. Baldwin, A.Some chemicals with cas registry numbers like 4399-55-7 and 6527-70-4 are also used. Frank (Burlington Industries, Inc., USA). U.S. US 4408996 A 11 Oct 1983, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: D06P005-02; A01N001-02; B05D003-02; A61F013-00. NCL: 008490000. APPLICATION: US 81-310416 9 Oct 1981. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 40 A dyed, absorbent, bioactive wettable medical fabric is prepd. from a wettable hydrophilic epoxy-polyoxyalkylene-modified silicone polymer, a direct dye and a bioactive silyl quaternary amine. The mixt. is applied to a nonwoven cellulose-contg. substrate, then heated to dye the coated substrate, fix the dye and couple the microbiocide and the coupling agent to the substrate. The fabric thus produced is useful as an absorbent surgical drape or dressing while providing a microbiocide to destroy the bacteria. Thus, a mixt. of 3-(trimethoxysilyl)-propyloctadecyldimethylammonium chloride [88132-76-7] 1.0, hydrophilic coupling agent 1.0, direct dye 0.035-0.35, binder 1.5-4, and alc. 1.0% and water balance is applied to a nonwoven cellulose substrate. .
