Abstract

Process of manufacturing spun-bonded fabric, using naturally crimped filaments, whereby the filaments are passed through a stretching unit and finally through a diffusor. The filaments are thereupon layered on a layering device, as crimped filaments. The layered filaments together with the layering device are passed through a solidifying device in which the filaments are solidified by means of a fluid.
