Process for the production of a multilayer fabric comprising the steps of: (a) feeding at least a first fabric (101) and a second fabric (102) to a constraining device (15), wherein the first fabric (101) is a non-woven fabric, comprising a plurality of filaments adapted to be crimped, preferably bicomponent filaments; (b) constraining said first and said second fabric (102) to each other, so that to define a plurality of constraining points or zones (P) between said first fabric (101) and said second fabric, and so that said first and second fabric (102) are superimposed; (c) heating said first and second fabric (102), so that the filaments of the first fabric (101) develop a crimp, thus increasing the thickness of the first fabric (101) and shrinking the length and the width of the first fabric (101), the shrinking of the first fabric (101) being greater than the shrinking of the second fabric (102).
Process for the production of a multilayer fabric (100) comprising the steps of:
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 first fabric (101) develop a crimp, thus increasing the thickness of the first fabric (101) and shrinking the length and the width of the first fabric (101), the shrinking of the first fabric (101) being greater than the shrinking of the second fabric (102).
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 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.
