Abstract
A multilayer fabric includes a first fabric and a second fabric superimposed onto each other. The first fabric is a non-woven fabric comprising a plurality of crimped filaments, the crimped filaments including a plurality of crimps. The first and second fabrics are constrained to each other at a plurality of constraining points or zones, wherein the surface of the second fabric has an area greater than the area of the first fabric. At least one portion of the second fabric disposed between adjacent constraining points or zones, has a plurality of bulgy zones, the bulgy zones protruding outward from the surface of the multilayer fabric.
Claims19
A multilayer fabric (100) comprising a first fabric (101) and a second fabric (102) superimposed onto each other, wherein said first fabric (101) is a non-woven fabric comprising a plurality of crimped filaments, said crimped filaments including a plurality of crimps and said first fabric (101) and said second fabric (102) being constrained to each other at a plurality of constraining points or zones (P), wherein the surface of said second fabric (102) has an area greater than the area of said first fabric.
A multilayer fabric (100) comprising a first fabric (101) and a second fabric (102) superimposed over each other, wherein said first fabric (101) is a non-woven fabric comprising a plurality of filaments, said first fabric (101) and said second fabric (102) being constrained to each other in a plurality of constraining points or zones (P), said first and second fabric (102) being configured such that most filaments of the first fabric (101) are crimped filaments that include a plurality of crimps such that the thickness of the first fabric (101) is greater than the thickness of the second fabric (102) and the length and width of the first fabric (101) is less than the length and width of the second fabric (102).
A multilayer fabric (100) comprising a first fabric (101) and a second fabric (102) superimposed onto each other, wherein said first fabric (101) is a non-woven fabric comprising a plurality of filaments, said first fabric (101) and said second fabric (102) being constrained to each other in a plurality of constraining points or zones (P), said first and second fabric (102) being configured so that, following a heating, the filaments of the plurality of filaments of the first fabric (101) each develop a plurality of crimps and have a wavy and irregular pattern thus increasing the thickness of the first fabric (101) and shrinking the length and the width of the first fabric (101) greater than the shrinking of the length and the width of the second fabric (102).
