A formed film includes a first surface generally located in a first plane, a second surface generally located in a second plane parallel to and spaced from the first plane, and a third surface generally located in a third plane parallel to and spaced from the first plane and the second plane, in between the first plane and the second plane. A porous structure extends between the second surface and the third surface. A plurality of raised areas have sidewalls that extend between the first surface and the third surface, and top portions that define the first surface. The plurality of sidewalls, the porous structure, and the first plane define a plurality of gathering volumes.

The present invention relates to a method of preparing a water-based surface treatment agent and a water-based surface treatment agent prepared using the same. More particularly, the present invention relates to a water-based surface treatment agent used to form a surface treatment layer included in artificial leather for automobile seat covers and a method of preparing the water-based surface treatment agent. According to the present invention, when the water-based surface treatment agent is used to manufacture artificial leather, occurrence of whitening of the surface of the artificial leather may be prevented.

Implanted medical devices need a mechanism of immobilization to surrounding tissues, which minimizes tissue damage while providing reliable long-term anchoring. This disclosure relates to techniques for patterning arbitrarily shaped 3D objects and to patterned balloon devices having micro- or nano-patterning on an outer surface of an inflatable balloon. The external pattern can provide enhanced friction and anchoring in an aqueous environment. Examples of these types of patterns are hexagonal arrays inspired by tree frogs, corrugated patterns, and microneedle patterns. The patterned balloon devices can be disposed between an implant and surrounding tissues to facilitate anchoring of the implant.

A sheet is used for a disposable wearable article. The sheet is such that a plurality of projections are formed on a single nonwoven fabric. A hole is formed in the apex of the projection. The projection includes a holding portion, in a periphery of the hole and at a position adjacent to the hole, for holding the projection and holding an open state of the hole.
