Abstract
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 of 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. The products may also have improved wet physical properties when regenerated cellulose fibers are presented, such as improved wet tensile strength and wet burst. The improvement in wet physical properties does not come at the expense of dispersibility, as the products are readily dispersible and, in some instances, have improved dispersibility compared to similar products prepared entirely from conventional wood pulp fibers.
