Uniform dyeing of meshware of cellulose fibers in hose form with water-insoluble azo dyes produced on the fibers

Uniform dyeing of meshware of cellulose fibers in hose form with water-insoluble azo dyes produced on the fibers. Jeths, Johannes (Hoechst A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3242155 A1 17 May 1984, 13 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: D06P003-68. APPLICATION: DE 82-3242155 13 Nov 1982. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Tubular cellulosic knits are azoically dyed fast shades by pretreating the knit, before impregnating with the coupling component, with a cationic compd. based on a dicyandiamide-formaldehyde condensate and a combination wetting agent contg. a Na alkyl sulfonate and a condensate [9043-30-5] of 1 mol isotridecanol with 8 mol ethylene oxide, rinsing, and dyeing with components to form azo dyes. Thus, a cotton knit was treated with a bath contg. 5 g/L of a condensation product from ethylenediamine sulfate 1, dicyandiamide 2, and formaldehyde 4.7 mol and 2 g/L of a 25% aq. soln. of sodium alkyl sulfonate contg. 10% of isotridecanol-ethylene oxide condensate and rinsed. The textile was impregnated with a compn. contg. C.I. Azoic Coupling Component 28, rinsed, and treated with C.I. Azoic Diazo Component 3 to give a level dyeing without any fold faults.

Surface-active polyglycol ether acetals

Surface-active polyglycol ether acetals. Heiss, Lorenz (Hoechst A.-G. , Fed. Rep. Ger.). Ger. Offen. DE 3318592 A1 22 Nov 1984, 6 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C043-11; C07C043-115; B01D017-04; B01F017-42. APPLICATION: DE 83-3318592 21 May 1983. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Acetals RO[(C2H4O)xCHR1O]z(C2H4O)yR2 (R and R2 = H, alkyl, etc.; R1 = alkyl, aryl, etc.; x and y = 5-20; z = 1-10) are prepd. for use as wetting agents, emulsifiers, demulsifiers, etc. Thus, a surfactant HO[(C2H4O)9CH(C12H25)O]6(C2H4O)9H was prepd. by the reaction of 0.3 mol isotridecanal with 0.34 mol polyethylene glycol (mol. wt. 400) in the presence of a strongly acid cation exchanger in toluene with azeotropic distn. of 5.4 g H2O. Another surfactant C13H27O(C2H4O)8CH(C8H17)O(C2H4O)8C13H27 was prepd. similarly from 0.165 mol isononanal [35127-50-5] and 0.3 mol polyethylene glycol monoisotridecyl ether [9043-30-5].
