Abstract
The invention relates to a method for plain dyeing a textile web of fabric by means of a padding mangle. The squeezing force distribution between the rollers of the padding mangles is controlled according to the dye distribution in the web of fabric which is still provided with the initial humidity on the output of the padding mangle, whereby the dye distribution is measured on certain points by means of a dye measuring appliance. Measuring the dye of the humid web of fabric is simplified and the measured result is improved when a dye receiver is used as the dye measuring device, whereby the receiver separately detects the radiation of a white light source according to pure dyes, the radiation being reflected on the web of fabric in a diffuse manner.
