Abstract (en)
[origin: WO2020025440A1] The invention relates to a nonwoven material (100, 101) and to a wiping cloth (200), a face mask (300) and a drying cloth (400) comprising the nonwoven material (100, 101), having a network (1) of shaped bodies (2), wherein the nonwoven material (100, 101) in the dry state has a specific opacity of greater than or equal to 1.0 %∙m2/g. In order to create a nonwoven material (100, 101) having a low mass per unit area which can be produced easily and has a high specific opacity without special modifications, it is proposed that the shaped bodies (2) are regenerated cellulosic shaped bodies (2) and are integrally connected to one another by node points (3) to the network (1), wherein the regenerated cellulosic shaped bodies (2) comprise individual filament portions (4) which extend between node points (3) and which vary in diameter (7) along their longitudinal extension (6) and over at least 90% of their longitudinal extension (6) have a diameter (7) of less than or equal to 15 µm.
