Abstract
An inner lining fabric of reduced thickness and having a down-fill composition for use as an inner lining in an article of apparel and a method of making the inner lining fabric is disclosed. A patterned envelope is formed and defines a pouch in which down or a down composition is inserted and distributed substantially evenly within the envelope. The envelope is then compressed in portions thereof and stitch seams are formed to define a quilt pattern of closely spaced stitch lines to reduce the loft of the down-fill composition by at least twice the normal loft thereof. This procedure is repeated over the entire envelope whereby the inner lining fabric has at least half the thickness of the normal loft of the down-fill composition. The inner lining fabric may have portions thereof with quilting defining surface areas of different portions to vary the thermal insulating value of different portions of the inner lining.
