Flexible high-stretch laminate with surface skins and coiled-filament non-woven fabric spacer

Abstract

Abstract A FLEXIBLE LAMINATE DESIGNED FOR USE IN THE FORM OF INTERNALLY OPEN HIGH-STRETCH SHEET MATERIALS HAVING HIGH COMPRESSION RESISTANCE. THE LAMINATE IS COMPOSED OF TWO SURFACE LAYERS OR SKINS SECURED TO AN INTERMEDIATE ELASTIC NON-WOVEN SPACER FABRIC HAVING HIGH MULTI-DIRECTIONAL STRETCHABILITY PROVIDED BY TRANSVERSELY INTERSECTING WARPS AND FILLINGS OF RESILIENT HIGHLY EXTENSIBLE COIL STRANDS OF MONO-FLAMENTARY NATURE. THE SPACER FABRIC IS MADE BY FORMING A FIRST COIL STRAND SINGLE LAYER STRUCTURE, FORMING A SECOND COIL STRAND SINGLE LAYER STRUCTURE SO THAT THE COIL STRAND REACHES OF THE LATTER OVERLIE AND ACROSS THE COIL STRAND REACHES OF THE FIRST LAYER ON ONE SIDE OF THE LATTER ONLY, AND COMPACTING THE TWO COIL STRAND LAYERS INTO ONE ANOTHER SO THAT THE COIL STRAND REACHES OF EAC LAYER ARE ENTANGLED WITH THE CROSSING AND STRAND REACHES OF THE OTHER LAYER FROM ONE SIDE ONLY AND ARE INTERCONNECTED SO AS TO BECOME A COHESIVE STRUCTURE IN WHICH THE AXES OF ALL THE COIL STRAND REACHES ARE IN A SINGLE COMMON PLANE. THE SURFACE LAYERS OF SKINS MAY BE EITHER PERMEABLE OR IMPERMEABLE SHEET MATERIALS.
