Description

ABSTRACT:
A woven, predominantly cellulosic fabric, such as an open-weave cotton-based fabric, having at least about 11 percent stretchability in the weft direction with less than about 6 percent growth (after repeated wash-dry cycles) and having wrinkle resistance and shrinkage control within commercial tolerances, is produced by first subjecting a woven, predominantly cellulosic fabric precursor to warp-wise tension while maintaining the fabric in a relaxed state in the filling direction. Next, the fabric is contacted with aqueous alkali while maintaining the aforesaid warp-wise tension, after which the thus-mercerized fabric is subjected to a tensile force in the filling direction sufficient to impart to the fabric, while said force is being applied and while maintaining warp-wise tension, a width of within about -1 and +3 percent of the initial greige width. The fabric is then washed with water to substantially remove the aqueous alkali while maintaining warp-wise tension. The fabric is next contacted with anhydrous liquid ammonia under warp-wise tension and then subjected to compressive shrinkage.
