Abstract: Disclosed is an apparatus for dyeing a bundle of fibers, such as a sliver, wool top or a synthetic-fiber tow. A bundle of fibers is accumulated into a dyeing can, comprising a main can and an auxiliary can, and, then, the bundle of fibers in the auxiliary can is pressed from above to pack the bundle of fibers in the main can in the compressed condition. Thereafter, the auxiliary can is separated from the main can. Next, a plurality of full packaged main cans are arranged in a predetermined positional relationship which conforms to the layout of the main cans in a dyeing bath and the full packaged main cans are charged into the dyeing bath while maintaining their prepared positional relationship. Then, the dyeing operation is carried out. After completion of the dyeing operation the main cans are taken out from the dyeing bath and are turned over so as to take out the packed bundle of fibers therefrom.

Abstract: A dyeing apparatus is disclosed, which comprises a vessel and a perforated cylinder or beam concentrical thereto, the cylinder having a material wound thereon which is to be dyed. A confining non-perforated cylinder is interposed concentrically between the vessel and the beam and provided with a longitudinal opening through which dye liquid, after passing through the layer of the material, is allowed to overflow to the bottom of the vessel.

Abstract: An apparatus for liquid treatment and drying of bobbins having a cylindrical container and an insert with one or more distribution chambers from which horizontal distributor pipes extend in parallel.

Abstract: The disclosure relates to a high speed process for bleaching greige cloth. The system involves bleaching of the cloth in roll form, in multiple roll batches, utilizing a forced circulation of high temperature liquid bleach at superatmospheric pressures. In the preferred system, a rack, containing a plurality of rolls of greige cloth, is loaded into a pressure vessel. The rack includes means for connecting the several rolls of cloth individually to separate pumps and heat exchangers. Bleaching liquid is pumped through heat exchangers, heated to a high temperature, and thus forced through the rolls. A preferred bleaching material is hydrogen peroxide, but other conventionally used liquid bleaches may also be used in the process. Although the bleach material is introduced into the cloth at a substantially elevated temperature, it is kept from vaporizing by maintaining the bleaching vessel under superatmospheric pressure.

Abstract: Yarn is wound back and forth around a given axis to form a tightly wound package, whereupon dye is fed into the bottom of the package, with the axis thereof vertically arranged, and forced to flow radially outwardly through the bottom turns of the package to take up the dye and color at least the lower end of the package. Alternatively, water will first be similarly fed through the package adjacent the bottom thereof, the wicking action of the yarn carrying the water to a level above the top level to which dye is then fed through the yarn in the manner stated. The wicking action of the water prevents the application of the dye from extending above the top level at which the dye is supplied to the package, thus giving a sharp color cut off, whereas with the unwatered package, the application of the dye is such that the wicking action carries the dye to a higher point, the intensity of the color progressively diminishing upwardly.

Abstract: This invention provides for a process for the wet treatment of textiles in which in a pressure-tight high-temperature resistant container the liquor always flows outwardly laterally at an angle from vertical through the inside of the textile material, flows down on the outside of the textile material to a sump situated beneath the latter and is pumped back from the sump into the interior of the textile material. Thus the material during the process is not immersed in the liquor and the influence of the high pressures and temperatures conventionally applied upon the textiles in their wet treatment is avoided and a lower liquid to textile ratio is employed.
