Abstract
An insulation material structure having crimped continued filaments interposed between staple fiber webs. Crimped continued filament web is interposed between an upper and lower natural or synthetic staple fiber webs having low melty fibers therein. After subjecting to cross-laid lamination-forming process and thermal setting, a resilient, composite laminated layered structure is formed. The laminated layer structure is subsequently cut, sewed, and stitched onto the facing and lining fabrics located at the upper and lower layers to form a stretchable insulation material structure having multiple fiber layers.
