Abstract: The invention relates to a nonwoven as well as to a wipe, a face mask, and a dryer sheet including the nonwoven, which includes a network of molded bodies, the nonwoven, in the dry state, having a specific opacity of greater than or equal to 1.0%·m2/g. In order to create a nonwoven of low basis weight, which is easy to produce and has, without special modifications, a high specific opacity, it is proposed that the molded bodies are regenerated cellulosic molded bodies and are materially interconnected via node points to form the network, and the regenerated cellulosic molded bodies comprising monofilament sections extending between node points, whose diameter varies along their lengthwise extension and which have a diameter of less than or equal to 15 ?m for at least 90% of their lengthwise extension.

Abstract: This invention relates to a process and a device for manufacturing cellulose-based webs which are directly formed from lyocell spinning solution and in particular for the washing of directly formed cellulose webs.

Abstract: This invention relates to a nonwoven material consisting of one or more layers of nonwoven webs of essentially continuous cellulosic filaments, characterized in that within each layer each of the three bonding mechanisms: a) hydrogen bonding, b) filament intermingling and c) merged filament bonding occur for bonding the essentially continuous cellulosic filaments. Further it relates to a process for the manufacture and to various uses of this material.

Abstract: A composite nonwoven fabric (1, 51, 61) and a process (100, 101, 102) for the production of the composite nonwoven fabric (1, 51, 61) are shown, wherein the composite nonwoven fabric (1, 51, 61) comprises at least one spunbonded nonwoven (8, 54, 64), which exhibits essentially continuous regenerated cellulosic filaments (4, 55, 65) deposited in a random orientation, and at least one layer (52, 62) of biobased biodegradable short fibers (14, 53, 63). So as to provide a fully biodegradable composite nonwoven fabric of the initially mentioned type, which exhibits a high stability and tensile strength as well as good absorption properties and haptic properties and, in addition, can be produced in a cost-efficient way, it is suggested that the composite nonwoven fabric (1, 51, 61) has at least one mixing area (56, 66) in which the filaments (4, 55, 65) of the spunbonded nonwoven (8, 54, 64) and the short fibers (14, 53, 63) are present in a state of physical interconnection.
