Process for the hydrodynamic solidification of a substantially homogeneous layer of fibers of any type and equipment for carrying out the process

摘要

It is a finite Good be obtained from a nonwoven, the edges of which are fully solidified, but the middle area remains voluminous. This is achieved by means of the advantageous binder-free hydrodynamic consolidation, that the fleece coming from a nonwoven laying device, such as carding, is first solidified at least on the entire surface and then onto this pre-consolidated and thus also re-submitable web in a continuous two-stage hydrodynamic consolidation process only along spaced longitudinal strips and superimposed equally spaced transverse strips by means of a plurality of rows of water jets and solidified by. If the nonwoven is cut after treatment at the points of full solidification, then the desired products are formed.
