Abstract
The process of dyeing textiles, especially closely woven or twisted materials, with vat or sulphur dyestuffs, or stripping such dyestuffs from textiles dyed therewith, is carried out in aqueous baths containing, in addition to alkali and a reducing agent, e.g. hydrosulphite or sodium sulphide, from viscous to solid polymerization products of ethylene oxide, which are obtainable by acting with strong alkali on ethylene oxide in accordance with the process of Specification 346,550. Examples are given (1) of the dyeing of mercerized pearl yarn and closely woven linen material with Indanthrene blue G.C.D. or Indanthrene violet 2 R extra; (2) of the stabilization of vats containing indigo or Indanthrene yellow G.; and (3) of the stripping of calico dyed with Indanthrene violet 2 R. or Indanthrene blue green B.
