Definitions

  • the present invention relates to a process for dyeing a textile material with indigo according to the preamble of claim 1 and an installation for carrying out the method according to the preamble of claim 8.
  • an indigo-dyed textile yarn is produced, which then makes it possible to prepare a fabric called denim fabric with which articles such as blue jeans are made, for example.
  • Indigo is one of the oldest known dyes and has been used for centuries to tint textiles such as cotton.
  • the patent EP-B-0 692 042 discloses a process for dyeing a cellulose-containing textile material with indigo in which an aqueous solution of leucoindigo prepared by catalytic hydrogenation is used and converted to the pigment form by air oxidation after its rise on the textile material.
  • the U.S. Patent No. 4,283,198 discloses a continuous process for dyeing cellulosic fibers with indigo where the fibers are passed through a quenching tank train containing a liquor bath comprising leuco-indigo, sodium hydrosulfite and sodium hydroxide.
