A brush for post chemical/mechanical polishing cleaning of a semiconductor wafer is provided, the brush comprising a microporous core with open cell pores and an outer layer of a plurality of loop fibers formed on the outer surface of the microporous core, wherein the brush has a first core flow resistance R1, a second through surface flow resistance R2, and a third flow resistance R3 across the surface and wherein R3<R1<R2.

An applicator device for applying a fluid or paste product to keratin fibres or to the skin (epidermis), that includes an elongate core which extends along a longitudinal axis X and has a longitudinal cylindrical shape and a plurality of projections distributed across said core, each projection extending from an anchoring end in the core towards a free end and being integral with said core, and each projection having, at the free end, a means for the uptake and retention of a quantity of fluid or paste product.

A brush for cosmetic implements includes a brush part attached to a support member; the brush part includes a plurality of synthetic resin fibers whose tip end has a conically tapered surface, and a plurality of fiber bundles composed of a plurality of synthetic resin fibers is formed at least three places in a radial circumferential surface of the support member, and further formed in an axial direction of the support member. Provided is a brush for a cosmetic implements in which a brush bristle having a tapered end is provided around the support member in the radial direction, and a manufacturing method thereof.

An apparatus for bending brush fibers has a rotating shaft with an outer surface along which a flexible backing strip of a brush partially wraps around to dispose fibers extending from the backing strip outwards as such brush travels along the outer surface of the shaft, and an energy delivery head, positioned along the backing strip when curving around the shaft, bends the fibers as the backing strip travels along the outer surface of the shaft. Energy delivered by the head deforms the fibers, when being bent by the head, to retain at least a portion of the fibers bent at an angle to provide an angled brush. The angled brush has fibers each deformed along a region, at a location between the backing strip and the end or tip of the fiber, to bend at the angle from the region to the end or tip of the fiber.

A brush useful for washing external surfaces, such as of a vehicle. The brush comprises a plurality of bristles connected to a hub. Each bristle has an elongated shaft having a number of cleaning structures extending outwardly from the shaft, providing multiple faces and edges arranged in a circumferential manner around the shaft, and producing multiple washing actions by the bristles as they are moved adjacent the surface. The hub and bristles may be integrally molded in a first condition having a planar form, and then folded relative to the hub to position the bristles extending from the hub in a cleaning direction from the hub. The hubs are secured to mounting structures by reception of the hubs in apertures in the mounting structures. In an embodiment, the mounting surfaces comprise flexible stanchions which are moved relative to an external surface to provide high resolution washing of a vehicle surface.

Apparatus and methods for an apparatus and method for a top wrap assembly is disclosed. The top wrap assembly includes a plurality of buns, wherein the plurality of buns comprises a plurality of assembled layers, wherein the plurality of buns defines a central bore, at least one shaft, wherein the at least one shaft is disposed in alignment with the central axis of the plurality of buns, wherein the at least a shaft is passes through the central bore, and a plurality of locking mechanisms, wherein each locking mechanism is configured to engage with the plurality of buns and the at least one shaft, wherein the locking mechanism is configured to secure the plurality of buns and the at least one shaft. The method comprises using the at least one shaft to execute the process described above.

Grooming tools are provided, including a brush configured for removing debris and hairs, including at least one surfaced body having a first pad, a plurality of first bristles extending from the first pad, one end of each first bristle being connected to the pad, and the bristles being helical in shape. A multi-purpose comb includes a housing having a pair of sidewalls defining a central cavity, and a plurality of foldable combs pivotably mounted at corresponding ends to the housing for insertion into, and withdrawal from the cavity.

A brush configured for removing debris and hairs is provided. Included in the brush are at least one surfaced body having a pad, and a plurality of first bristles extending from the pad. One end of each first bristle is connected to the pad, and an opposite free end of each first bristle has a radially extending head portion. At least one additional head portion is disposed in a spaced relationship along a longitudinal axis of the first bristle.

An applicator for applying a cosmetic composition to the eyelashes or eyebrows, including a core, at least one element attached to the core, each element comprising a central part fitted onto the core and at least one application member carried by the central part, this application member having a proximal half attached to the central part and a distal half extending outward from the proximal half, a composition collection surface being formed by a relief on the distal half that defines a concavity that is open radially toward the outside.

A color coded oral care implement packaging system. In one embodiment, the system includes a first packaged oral care implement that includes a package and an oral care implement having a tooth cleaning element field with a first characteristic positioned within the package. The system also includes a second packaged oral care implement that includes a package and an oral care implement having a tooth cleaning field with a second characteristic positioned within the package. The first package includes a first designated area being color coded with a first color selected to represent the first characteristic. The second package includes a second designated area being color coded with a second color selected to represent the second characteristic.
