Abstract
A three-dimensional camouflage fabric is produced in a multi-head quilting machine by sewing a multiplicity of transversely spaced, elongated strips of relatively narrow fabric on a relatively wide web of a substrate fabric along laterally spaced lines of attachment positioned between the side edges of the strips. The strips are attached to the substrate in a longitudinal wrinkled condition, giving the strips a three-dimensional contour. The side edges of the strips are formed in an irregular pattern, with edge patterns of adjacent strips being different. The edges of the strips desirably overlap so as to enhance the three-dimensional appearance. The strips can be wrinkled by feeding the strips at a faster rate than the substrate. This can be achieved by a spring feeding mechanism or by sewing the strips at an inclined angle to the substrate.
