Abstract
A method for dyeing of textiles in a liquid bath and an apparatus for performing the process which effectively stirs the dye bath resulting in a more homogeneous color distribution in the bath. The method also results in a faster drying process of the goods. Thus, the dyeing processing time has been reduced while the dyeing of the goods has been made more uniform.
Claims1
The method for dyeing textile fabrics in a liquid bath wherein said fabrics are placed in a perforated drum that is rotatably mounted on a horizontal shaft in a closed container having a door, comprising the steps of:
- bringing a textile dyeing liquid into said drum, rotating said drum at tumbling speed, increasing the rotating speed of the drum repeatedly during short periods of time from a tumbling speed to a speed level whereby the fabrics are distributed about the inner periphery of the drum and pressed against said periphery to avoid relative movement between the fabrics and the drum, draining off said treatment liquid, and extracting the remaining humidity from the textile fabrics.
