Abstract: The initial moisture content of textile material to be decatized and fixed is controlled by a feedback-type regulator circuit which is responsive to measured values of the water content of vapor clouds produced as the material emerges from its passage around a steaming cylinder. The moisture content is preferably controlled by regulating the amount of water applied by a moistening device upstream of the steaming cylinder.

Abstract: An apparatus for the steam conditioning of lengths of textile fabrics includes a frame carrying a fabric spreader for spreading of the fabric in a spreading zone, steam boxes for application of steam to the spread fabric within a steam zone, a cooling zone, and fabric advancing mechanism for advancing the fabric through the steam and cooling zones. A duct system encloses the steam boxes and, in conjunction with one or more blowers, evacuates steam upwardly and downwardly from a region adjacent the steam boxes thereby confining the steam zone to the region between the discharge sections of the steam boxes and preventing the migration of steam to areas upstream and downstream of such steam zone.

Abstract: Process and apparatus for mixing a wood pulp slurry with a chemical at the consistency at which the slurry exits a washer or the subsequent steam mixer, 7 to 15%. The chemicals would include noncondensable or unsaturated gases such as oxygen, ozone, air, chlorine, chlorine dioxide, sulfur dioxide, ammonia, nitrogen, carbon dioxide, hydrogen chloride, nitric oxide or nitrogen peroxide. Highly superheated steam can also be mixed with the pulp.In the process, the pulp slurry would pass through a mixing zone having a swept area in the range of 10,000 to 1,000,000 square meters per metric ton of oven-dry pulp. The preferred range is 25,000 to 150,000 square meters per metric ton of oven-dry pulp and the optimum is considered to be around 65,400 square meters per metric ton of oven-dry pulp.The pulp slurry passes through an annular mixing zone. Specific designs of the various elements of the mixer are disclosed.

Abstract: A design of a distribution unit allowing a gas or other material to be uniformly supplied to a mixing device close to the point of mixing. The distribution unit can be used for mixing chemicals into pulp at a refiner inlet.

Abstract: Process for the uniform drying of a travelling textile web impregnated with treating agents by contacting the textile web oscillatorily over its width with the hot air current or heat radiation supplied by the corresponding sources of heat and hitting the web unilaterally or bilaterally. Devices for carrying out this process are described.

Abstract: The invention relates to the printing of sheet-heavy-pile textile materials, especially carpets, characterized in that powdered dyestuff preparations are applied to the sheet of textile material in consistency with the pattern, preferably by the screen- printing or film-printing techniques, the dye is subsequently fixed by the action of heat and any constituents of the dye preparations which are not fixed are removed by suction or by washing. The new method is economical and causes no or little pollution.

Abstract: A method and apparatus for effecting the transfer printing of discrete cut-pieces of goods on a continuously rotating, drum type, transfer printer. The method and apparatus includes a rotary drum printer in which the rotary drum is reciprocally moved toward and away from a feed station in which the discrete goods are fed onto a continuous web of material having a transfer print thereon. The arrangement is such that when the drum is moved away from the feed station, the web and cut pieces thereon are indexed a corresponding amount, and when the rotating drum is moved toward the feed station, the web is held relatively motionless, thereby permitting the feeding of discrete cut-pieces thereon, permitting the drum to continue rotating to effect the transfer printing of the cut pieces previously fed into the web.
