  • Patent number: 3961884
    Abstract: Process for the continuous dyeing of polyester fiber/cellulose blends with disperse dyestuffs and water-insoluble azo developing dyestuffs by padding the fibrous material with an aqueous solution of at least one ice-color coupling component, an alkaline agent and an alkali metal nitrite, then cross-padding the material so impregnated with a second aqueous bath of room temperature which contains at least one diazotizable amine, at least one thermosolable disperse dyestuff and an acidifier, and finally successively promoting the formation of the azo dyestuff by diazotizing and coupling as well as fixing the disperse dyestuff with the aid of elevated temperature.

  • Patent number: 3953487
    Abstract: Process for preparing hydrophobic SiO.sub.2 by reacting solid SiO.sub.2 of finest particle size with organosilicon compounds while subjecting the reaction mixture to a mechanical impact treatment which will at the same time result in a comminution of the SiO.sub.2 particles as well as of their aggregates, said process comprising incorporation to the reaction mixture, in addition to the water adsorbed by the SiO.sub.2, an amount of 0.3 to 3% by weight of water calculated on the weight of the SiO.sub.2.
