The present invention provides a wet-laid tissue product comprising regenerated cellulose fibers that can provide 25 percent or less of the total weight of the wet-laid tissue product. The regenerated cellulose fibers can have a linear density less than about 1.5 dtex and a fiber length of less than 6.0 mm. The wet-laid tissue product can provide improvements in softness at a given strength.

Nonwoven substrates and methods for making nonwoven substrates are provided. The nonwoven substrates have a first material layer containing a first plurality of fibers, a second material layer containing a second plurality of fibers, and a third material layer containing a third plurality of fibers. A first outer surface is formed from the first material layer. The nonwoven substrate has a plurality of elevated regions and a plurality of non-elevated regions disposed on the first outer surface. Fibers of the third plurality of fibers are disposed on the first outer surface in at least some of the plurality of elevated regions.
