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.
Claims9
An insulation material structure comprising an upper staple fiber web, a lower staple fiber web, and a crimped continued filament web interposed between the upper and lower staple fiber webs, the webs being subject to a cross-laid lamination-forming process and a thermal setting treatment, thereby forming a fiber laminate having stretching recovery properties, wherein the fiber layers are capable of resiliently sliding with respect to each other, the fiber laminate being cut, sewed, and stitched onto a facing fabric and a lining fabric located at the top and bottom of the insulation material structure respectively, whereby the insulation material structure is formed to have multiple fiber layers.
