Abstract
Woven or knit fabric is pre-tentered (stretched) prior to hydroenhancement treatment to a predetermined width in excess of the desired finished width of the fabric. The pre-tentering width is selected so that the expected shrinkage caused by the hydroenhancing process reduces the width of the enhanced fabric to slightly less than the desired finished width. The fabric is post-tentered hydroenhancing process only by a slight amount to the exact desired finished width. Since only a slight increase in width is required, there is very little loss in cover of the enhanced fabric. Post-tentering to a slight increase in width will also provide a slight tension for holding the fabric in the tenter clips and prevent the fabric from dragging in the tenter.
