1. A nonwoven, comprising:
framework fibers;
an at least in part fused thermoplastic material; and
a thermally embossed mesh pattern comprising a plurality of intersecting embossed grooves, between which a plurality of embossed elevations are arranged,
wherein the framework fibers are staple fibers having an average length from 15-85 mm,
wherein the framework fibers are not fused,
wherein an equivalent diameter of the embossed elevations is smaller than 50% of a fiber length of the framework fibers,
wherein a ratio of a width of the embossed grooves to a thickness of the nonwoven in a region of the embossed elevations is less than or equal to 4/5,
wherein a ratio of the width of the embossed grooves to a thickness of the nonwoven in a region of the embossed grooves is from 0.5 to 2, and
wherein the at least in part fused thermoplastic material is present in an amount from 5 wt. % to 25 wt. %, based on total weight of the nonwoven.
