The present disclosure is directed toward an improved nanofibrous electret filtration media of which the stand-alone electret nanofibrous web comprises a single source randomly intermingled fiber network that yields high breathability due to the high porosity and improved filtration efficiency for use as improved filtration media for respiratory devices and face masks.

Melt-blown webs having no shots and improved barrier properties, whereby the melt-blown webs are made out of a so-called controlled rheology propylene (CR-PP), which was visbroken without any peroxide.

A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.

A wet sheet for cleaning includes multiple layers and is impregnated with a chemical solution. The wet sheet for cleaning includes outer layers which are made of hydrophobic fiber and which are each arranged on a front surface and a back surface, and an inner layer which is made of hydrophilic fiber and which is arranged between the outer layers. The inner layer is provided with a hydrophilic fiber inner layer with the hydrophilic fiber and a hydrophobic fiber inner layer with hydrophobic fiber. The hydrophobic fiber inner layer is adjacent to at least one of the outer layers. The inner layer includes pulp by 50 wt % or more, has a grammage of 20 to 75 g/m.sup.2, and occupies 20 to 70% of a total mass of the wet sheet for cleaning.

The present disclosure is directed, in part, to webs or topsheets for absorbent articles and methods of making the same. The webs and topsheets include bicomponent fibers having a first component and a second component, wherein the first component has a different hydrophilicity than the second component. The webs and topsheets include a continuous land area and discrete zones of modified surface energy. One of the first and second components forms an outer surface of the fibers in the continuous land area and the other of the components at least partially forms an outer surface of the fibers in the discrete zones of modified surface energy such that the discrete zones of modified surface energy have a different hydrophilicity than the continuous land area.
