  • Patent number: 5426803
    Abstract: The present invention is a method for processing dye-liquors, in particular dye-liquors for textile dyeing and post-treatment facilities. In particular, the present invention makes it possible to minimize the waste portion, and even entirely eliminate dyeing accessories, while textiles are treated in one or more subsequent dyeing chambers with heated dye liquors. The textiles to be treated are pulled in continuous transit, in one direction, through the associated equipment. Direction-reversing systems ensure a plurality of lengths of said textile are simultaneously in the dyeing chamber while the dye liquor is constantly cleaned and replenished by an apparatus which removes and reintroduction the dye-liquor in the dyeing chamber.

  • Patent number: 5400453
    Abstract: The invention concerns a method for dyeing textiles, whereby textiles are loaded with a dye liquor containing dye in diluted form; several mutually separate dye compartments (dye containers) being provided and mounted in a zone above the dyeing chamber receiving the textiles to be treated. Several textile pieces are processed simultaneously in the dyeing chamber of which the base zone comprises supply lines with upwardly directed supply apertures for steam and for the dye liquor. Thus, it possible to deposit colors structured as pictures across wide areas and differing from each other on a variety of textiles. Furthermore, uniform dye soaking of the textiles is achieved in spite of such image designs. For that purpose, the invention provides that the dye liquor is made to pass from below to above through the textiles using pressurized transport media at raised pressure.

  • Patent number: 5375281
    Abstract: The instant invention provides a method for treating, in particular, for dyeing fabric warps, wherein the warps in the raw (white) state pass through a so-called sizing bath which rigidifies them and makes them more wear-resistant. The warps so treated are then woven and the textile so made is dyed in a manner to drastically lower costs. The invention calls for untreated warps in the raw (white) state to pass in-line through at least one bath containing the size in a single operational step, the dyes to be deposited being present as a viscous or pasty substance in the bath in addition to the size.

  • Patent number: 5197305
    Abstract: The invention concerns a method and apparatus for dyeing textiles wherein simultaneously the surfaces of these textiles are mechanically processed in such manner that wear shall appear and that the fabric softens, making it possible to minimize energy and material expenditures on one hand and ecological stress on the other.For that purpose the invention provides that the textiles in the form of finished pieces or yard goods are stressed in-line by the bristles of brushes through which simultaneously a dye liquor with a very low proportion of dye of the order of magnitude of approximately 0.01 to 0.05 g/liter is deposited on the textile pieces.
