Abstract: An insulated article that changes its fill power through adjustment in displacement is provided. Outer and inner surfaces of a folded web consisting of slanting lapped continuous filaments tow band are attached with an outer shell fabric and a lining fabric made of nonwoven or cloth, respectively. This forms a sandwich structure similar to the birds' down feathers underneath the contour feathers. By adjusting the horizontal displacement between the outer and lining fabrics, the fill power (or fluffiness) of the folded web can be changed. Thus, the present invention is applicable to products such as sleeping bags, duvets, snow suits, snow boots and the like. It also has sound and heat proof properties as well as better thermal insulation.
