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.
Claims4
Method for the single color-dyeing of a textile web of fabric by means of a coloring padding machine with an appertaining roller squeezer, comprising
- controlling the squeezing force distribution between the rollers of the padding machine in dependence on the dye distribution in the web of fabric, which still contains the initial dampness at the output of the padding machine,
- measuring the dye distribution at points by means of a color measuring instrument,
- and using a color receiver as dye measuring device, which receives the radiation of a light source diffusely reflected on the web of fabric, separated in pure colors;
- and
- wherein only the concentration of dye particles of a single pure color is used for the control of the squeezing force distribution for a mixed dye applied to the web of fabric.
