Anthraquinone dyes for polyester fibers

Anthraquinone dyes for polyester fibers. (Dainichiseika Color and Chemicals Mfg. Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58120669 A2 18 Jul 1983 Showa, 4 pp. (Japanese).Several reagents with their cas registry numbers 81-48-1 and 50667-60-2 are used here. (Japan). CODEN: JKXXAF. CLASS: IC: C09B001-16; C09B001-50; C09B001-56. APPLICATION: JP 82-3428 14 Jan 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) The title dyes have the general formula I, where R = HO, H2N, halo, MeO, EtO, MeO2C, EtO2C, PhO, O2N, and/or PhNH; m = 1-4; Z = O, NH, OCH2O, or S; R1 = OH, Me, Et, OMe, and/or OEt; and n = 1-2. I give uniform dyeings with high fastness to light and sublimation. Thus, II [88937-63-7], prepd. by condensation of 1-amino-4-hydroxy-2-phenoxyanthraquinone [17418-58-5] with 4,5,6,7-tetrachloro-N-(hydroxymethyl)phthalimide [50667-60-2] in H2SO4, gave fast red dyeings when applied to polyester from an aq. dispersion. Several other I were similarly prepd. Numerous examples are given in the use of I in combination with other anthraquinone disperse dyes. .

Effect of radial distribution of dye and delustering agent on remission properties of PES fibers

Effect of radial distribution of dye and delustering agent on remission properties of PES fibers.Some chemicals with cas registry numbers like 12217-79-7 and 13463-67-7 are also used. Ruzicka, Jaroslav; Prikryl, Josef; Burgert, Ladislav; Geri, Istvan (Czech.). Sb. Ved. Pr., Vys. Sk. Chemickotechnol. Pardubice, 45, 339-52 (Czech) 1982. CODEN: SVPVA9. ISSN: 0553-2124. DOCUMENT TYPE: Journal CA Section: 40 (Textiles) The color depth and hue of polyester fibers depended significantly on the concn. profile of C.I. Disperse Red 60 [17418-58-5] and C.I. Disperse Blue 71 [12217-79-7] in the fibers, as shown by remission measurements. The concn. profile of the dyes across the fibers was detd. by a microdensitometric method. Fibers with a nonhomogeneous dye distribution appeared to have a lower color depth than those contg. homogeneously distributed dyes. The overall color effect also depended significantly on the concn. of the delustering agent (TiO2). .
