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%·m/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 μm for at least 90% of their lengthwise extension.

Nonwoven material, use of the nonwoven material, and wiping cloth, dryer sheet and face mask containing the nonwoven material

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.

Process and device for the formation of directly-formed cellulosic webs

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.

Continuous filament cellulose nonwoven made with multiple bonding techniques

A nonwoven cellulose fiber fabric, in particular directly manufactured from lyocell spinning solution, wherein the fabric comprises a network of substantially endless fibers, and wherein the fibers are homogeneously merged substantially over the entire fabric.
