Abstract
The dyeing of textile fabrics conventionally calls for the wetting of fabric pile with a dye solution. Difficulties arise in achieving uniform wetting and consequently uniform dyeing of the textile fabric without expenditure of large amounts of energy or dyeing solution. The present invention solves the problem of uniform dyeing according to a process wherein the textile fabric is wetted with an unfoamed dyeing solution containing a foaming agent, followed by mechanical treatment by means of alternating compression and relief and finally, a steam treatment process.
Claims10

- (a) wetting a fabric with an unfoamed dyeing solution containing foaming agents;
- (b) exposing the wetted fabric to a mechanical treatment consisting of alternating compression and relief;
- and
- (c) subjecting the wetted, mechanically treated fabric to a steaming treatment.
