Claim:
A process for preparing a non-woven fabric material comprising a microfiber surface layer bonded to a macrofiber supporting layer, the method comprising: (a) needle-punching a mat formed by at least one layer of carded web of said macrofibers and at least one layer of carded web of said microfibers, and (b) treating the needle-punched mat with high pressure water jets to bond the surface layer to the supporting layer by spunlacing and hydroentangling the microfibers of the surface layer with the macrofibers of the supporting layer, and to split the microfibers into filaments, wherein said needle-punching (a) and said water jet treating (b) steps are both performed from a same side of the fabric material on a free surface of the microfiber layer that is not in contact with the macrofiber layer.
