Abstract

Textile materials comprising cellulose are dyed in a continuous process by means of an ester of a lenco vat dyestuff wherein a polyglycol ether of the formula <FORM:1018115/D1-D2/1> in which n is an integer from 7 to 10, is added to the padding bath. The preferred polyglycol ethers are those in which n is 8 or 9. Long lengths of material e.g. over 3,000 or even 10,000 metres, can be dyed by the present process. The padding bath may also contain a dispersing agent e.g. a formaldehyde/naphthalene sulphonate condensate. In the examples the padding treatment is effected at 40-50 DEG C and is followed by a passage in air, development in a sulphuric acid bath, a second passage in air, neutralisation and soaping.
