A process for producing a high extensibility nonwoven web comprising polymer fibers using a blend comprising at least one polypropylene and a polypropylene non-miscible further polymer and at least one block copolymer compatibilizer, wherein the block copolymer - At least one hydrophobic block (A), consisting essentially of isobutene units, and - At least one hydrophilic block (B), consisting essentially of oxalkylene units includes and where - the polypropylene and another polymer are mixed together in the presence of the compatibilizer under the action of heat, The mixture is then spun into fibers in an open or closed process, - The fibers are stored on a device and - The fibers are then thermobonded at discrete locations to form a nonwoven. |
