Patent number: 4428750Abstract: In order to achieve lighter patterned effects on a background of a deeper color, aqueous printing pastes containing, additionally to thickeners and other conventional printing assistants, assistants which have dissolving properties for the dyestuffs at elevated temperatures and which do not attack the fibers under thermosol conditions, are applied to textile webs which have been dyed in a finished manner with suitable dyestuffs or have only been impregnated therewith, after which the goods treated in this way are subjected to a steaming process or to a dry heat treatment. In accordance with the process it is possible to effect a uniform lightening, "white discharging" or "colored discharging" of dyeings, particularly dyeings of synthetic fibers with disperse dyestuffs and also dyeings of natural fibers or mixtures thereof with disperse dyestuffs, vat dyestuffs, leuco esters thereof and developing dyestuffs.Type: GrantFiled: February 18, 1983Date of Patent: January 31, 1984Assignee: Hoechst AktiengesellschaftInventors: Walter Birke, Hans-Ulrich von der Eltz, Franz Schon, Erich Feess

Patent number: 4207058Abstract: Apparatus for drying a continuously moving web containing a combustible organic liquid comprises a walled chamber through which the web passes. Ignition and heating means adjacent the inlet of the web to the chamber initiates combustion of the organic liquid. Enroute to the web outlet of the chamber the web passes between heat radiating members located on opposite sides of the web so as to define between the heat radiating members a main combustion zone. Hot waste gases of combustion are led from the main combustion zone to an after combustion zone defined in part by the heat radiating members and in part by guide members located within the the chamber. The waste gases are drawn through the after combustion zone to waste gas outlets by means of a suction fan, the heat radiating members being heated by the waste gases.Type: GrantFiled: August 2, 1978Date of Patent: June 10, 1980Assignee: Bruckner Apparatebau GmbHInventors: Gerhard Petersohn, Hans-Ulrich von der Eltz, Walter Birke, Franz Schon

Patent number: 3993434Abstract: Process for the fixation of prints with reactive dyestuffs, wherein an aqueous alkaline bath which contains an inflammable organic liquid is applied onto the printed and dried material, the said organic liquid is burned off after passage of the material through air and the said material is further treated in the usual manner.
