Abstract
After leaving the hot lye bath (2) the fabric web (1) is immediately cooled down in a cooling zone (C) and only then passed to a residence zone (5) in which the lye acts on the fabric. Stretcing of the fabric web is then effected in a widthwise stretching zone (E), wherein it is again heated, preferably by a feed of hot weak lye. That combination of method steps provides optimum mercerizing effects with careful removal of shrinkage of the fabric.
