Abstract
Abstract Waistband interlinings are made by ultrasonically cutting a fabric having warp yarns and fill yarns of a thermoplastics material along lines parallel to the warp threads. An acrylic finish on the fabric permits it to undergo the ultrasonic cutting, will retard the development of brittleness in the fused fibres, and keep the resulting fused edge intact. The fabric should have at least 30 fill yarns per inch but no more than 42 warp yarns per inch. The fabric is cut by passing it between a stationary pressing element, or knife, and the horn of an ultrasonic generator. The fill yarns melt as they pass between the knife and the horn and fuse into adjacent fill threads to form a continuous edge along the length of the cut fabric. The resulting waistband material has a smooth edge formed from fill, or weft, fibres fused to each other and to not more than one warp thread. The waistband interlining finds use in a waistband assembly for slacks and pants.
