Estimating the term…
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 μm for at least 90% of their lengthwise extension.
A nonwoven, comprising 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, wherein the molded bodies are regenerated cellulosic molded bodies and are materially interconnected via node points to form the network, wherein the regenerated cellulosic molded bodies comprise 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, and wherein the regenerated cellulosic molded bodies comprise multifilament sections extending between node points and being formed of two or more monofilament sections that are essentially parallel and that are connected with one another via cohesion of cellulose molecules, the multifilament sections having a diameter of less than or equal to 100 μm for at least 90% of their lengthwise extension.
