Superabsorbent fibers (SAF) in a feed stream is converted with UV irradiation into soluble polymers in a flow system. The UV total energy used to convert SAF into soluble polymers is less than about 50 MJ/kg SAF.

Recycling of superabsorbent fibers via UV irradiation in flow system

A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and wherein in at least one of the microzones, the first region is hydrophobic and the second region is hydrophilic.
