Abstract:
A process for treatment of a textile web with a treatment liquid containing a treatment medium, in which the textile web is continuously guided through a trough which contains the treatment liquid, and subsequently passes through a pair of squeezing rollers, comprising the steps of:using a test textile web to measure the concentration progression of the treatment liquid in the trough at a constant line force of the pair of squeezing rollers, as a function of the length of textile web that has passed through;using this information to determine a reference progression of the line force over the length of textile web that has passed through, using a previously determined relationship between a concentration change in the trough and the line force change of the pair of squeezing rollers necessary to balance it out, in such a way that the amount of applied treatment medium per surface unit of the textile web remains constant over the length of the textile web;treating a length of production textile web that is made of the same material, using the same treatment liquid and under the same treatment parameters, wherein when the treatment liquid is applied to the length of textile web, the line force of the pair of squeezing rollers is regulated on the basis of the reference progression.
