Patent

CA 2116996

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.

La présente invention vise une toile de faible épaisseur recouvrant une bourre de duvet ou de composition de duvet et utilisée comme doublure de vêtement, ainsi que la méthode de fabrication connexe. Une enveloppe texturée est d'abord façonnée, dans laquelle est introduit puis uniformément réparti le duvet ou la composition de duvet. L'enveloppe est ensuite divisée en portions au moyen de piqûres pour former un capitonnage serré de manière à réduire l'épaisseur de la couche de duvet ou de composition de duvet d'au moins de moitié. Les portions formées peuvent être de dimensions différentes selon la valeur d'isolation thermique qu'on veut assurer aux différentes parties du vêtement doublé.
