ABSTRACT OF THE DISCLOSURE A method is disclosed for mechanically preshrinking and drying of cellulosic fabric. The fabric is first moistened to 15% - 25% moisture content and is mechanically preshrunk, then conveyed about a heated dryer drum while being restrained dimensionally both length- and width-wise. the moisture content is reduced to about 5% to 14% and the fabric is conveyed through a loop dryer wherein it is arranged in loops and maintained in an essentially relaxed state while its moisture content is reduced to at least 4%, whereupon the fabric is removed from the loop dryer. The invention provides reduced capital investment, increases the speed of processing and improves the uniformity of the fabric finish.
