Abstract:
A method for dyeing textile webs made of polyester fibers or blends of polyester fibers with other fibers in a dye bath in a jig that has a first lap roll, a dye bath, and a second lap roll spaced from the dye bath via a reeling-on gap, comprising the steps of:unwinding the web from one of the lap rolls of the jig;passing the web through the dye bath;raising the temperature of the textile web an additional amount just prior to winding it onto the lap roll acting as a reeling roll by blowing saturated steam onto the textile web directly onto the web in advance of the location where the textile web winds onto the lap roll against the side of the textile web facing the lap roll;winding the web immediately onto that lap roll acting as a reeling roll of the jig, the winding direction being reversible after the run-through of the length of the textile web;wherein the dyeing is carried out under atmospheric pressure without air inlet or exchange with the ambient atmosphere in such a way that the boiling temperature of the dye liquor, or a temperature immediately below the boiling temperature is maintained in the dye bath.
