Azoic dyeing of polyester fibers

Azoic dyeing of polyester fibers. Ohige, Toshiharu; Sakai, Tamotsu; Honjo, Takeshige; Kawamura, Taizo (Shikishima Spinning Co., Ltd.; Asahi Chemical Co., Ltd., Japan). Japan. Kokai JP 52025182 24 Feb 1977 Showa, 9 pp. (Japanese). (Japan). 62758-83-2 is also in the experiment. CODEN: JKXXAF. CLASS: IC: D06P003-56. APPLICATION: JP 75-79178 24 Jun 1975. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Azoic dyeing of polyester fibers in light and medium shades uses Naphthol AS-D (I) [135-61-5], Naphthol AS-BS [135-65-9], or Naphthol AS-G [91-96-3] as coupler, and 4-(4-aminoanilino)-1-(2-hydroxyethylamino)anthraquinone (II) [62758-81-0] or 4-[4-(4-aminoanilinocarbonyl)anilino]-1-(methylamino)anthraquinone [62758-82-1] as diazo component. For example, a polyester cheese was impregnated with a I bath, heat-set, and woven with I-free polyester yarn, and the mixed weave was impregnated with a II bath contg. a dye migration preventive, heat-set, scoured, impregnated with a bath contg. 2 g/L NaNO2 and 2 g/L polyphosphate, and heat-treated at 95.degree. for 10 min to give a dyeing with a grayish brown shade on I-pretreated fiber and a reddish blue shade on fiber dyed with II alone. .

Synthesis and application of novel heterocyclic dyes based on 11-amino-13H-acenaphtho[1,2-e]pyridazino[3,2-b]quinazolin-13-one. Patel, Vijay H.; Patel, Manish P.; Patel, Ranjan G. (Department of Chemistry, Sardar Patel University, Vallabh Vidyanagar 388 120, India). Journal of the Serbian Chemical Society, 67(11), 727-734 (English) 2002 Serbian Chemical Society. CODEN: JSCSEN.Some chemicals with cas registry numbers like 91-96-3 are also used. ISSN: 0352-5139. DOCUMENT TYPE: Journal CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 28, 40 A new fused heterocyclic compd., 11-amino-13H-acenaphtho[1,2-e]pyridazino[3,2-b]quinazolin-13-one, was synthesized and used to prep. heterocyclic monoazo dyes by diazotization and coupling with 11 different naphthols. All the dyes were characterized by their m.p., elemental anal., UV-visible spectra, IR spectra, and dyeing performance on nylon and polyester fibers. The percentage dye bath exhaustion was reasonably good and acceptable. The dyed fibers showed fair to good fastness to light and very good to excellent fastness to washing, rubbing, perspiration, and sublimation. 91-96-3 is the cas registry number. This chemical is also mentioned in this article. ..
