Abstract (en)

[origin: WO2008080382A1] The invention relates to a method for the production of a one-layered or multilayered nonwoven fabric, a machine for the production of such a nonwoven fabric, and a correspondingly produced nonwoven fabric. The task of improving such a method and a production apparatus underlies the invention to the effect that projecting loops and fibrils no longer stick out, and thus individual filaments can be prevented from pulling out during the use of the nonwoven fabric. According to the invention, this is achieved in that the nonwoven fabric (14) is smoothed after water needling by the use of a calender (10). The machine according to the invention is characterized by the fact that the machine has a spun bonded fabric (1), at least one subsequent needling device (7.1), a dryer (9) connected thereto, and thereafter at least one calender (10).
