Dyeing synthetic polyamide fiber materials

Dyeing synthetic polyamide fiber materials. Kirschnek, Helmut; Jakobs, Karlhans (Bayer A.-G., Ger.). Ger. Offen. 26635-92-7 is the cas registry number. This chemical is also mentioned in this article. DE 2633615 2 Feb 1978, 18 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: D06P001-39. APPLICATION: DE 76-2633615 27 Jul 1976. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Polyamide fibers are dyed level fast shades with metal-free acid dyes using dyebaths contg. R[H(OCHR1CH2)x]N[(CH2)nN[H(OCHR1CH2)]y]m(CH2CHR2O)zH [R = C12-22 alkyl and(or) alkenyl; R1 = H and(or) Me; m = 0 or 1; n = 2 or 3, and x + y + z = 10-30] and R2AX [R2 = C12-22 alkyl and(or) an alkyl-substituted Ph and(or) naphthyl radical; A = OSO2 or SO3; X = H, NH4, alkali metal, alk. earth metal, C1-4 mono-, di-, or trialkylammonium or hydroxyalkylammonium, or cyclohexylammonium]. Thus, nylon 66 fibers were dyed at goods-liquor ratio 1:5 in a bath (pH 5) contg. I 0.8, II 1, and mixt. of 77 parts stearylamine polyethylene glycol diether [26635-92-7] and 23 parts dodecylbenzenesulfonic acid [27176-87-0] 0.52 g. Both dyes were simultaneously taken up by the fibers and a level green dyeing resulted. .

Lightly dispersible-in-water phthalocyanine preparations. Fabian, Wolfgang; Kranz, Joachim; Steockelmann, Guenter (BASF A.-G., Ger.). Ger. Offen. DE 2635214 9 Feb 1978, 22 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B067-00. APPLICATION: DE 76-2635214 5 Aug 1976. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 42 Dispersing phthalocyanine blue (I) [147-14-8] in org. solvents contg. alkylbenzenesulfonic acids and then evapg. gave H2O-dispersible pigments for use in paper coloring. Thus, a mixt. of 5 g cellulose pulp, 2 mL 5% rosin size, 3 mL 10% Al sulfate soln., 60 mg powd. pigment contg. 77% I and 23% dodecylbenzenesulfonic acid [27176-87-0] (particle size 2.1-100 m), and 600 mL H2O was filtered from a sieve with 30 m mesh width to give paper with dark greenish blue color.
