摘要:
A polymer filament molded product and a method of making a filament network that includes coating filaments with a latex polymer and shaping the filaments into a molded product; one in which a polymer is shaped and molded into a larger filament network. The molded products can be objects for apparel, home and garden, furnishings, health care, engineering, industrial and consumer goods. The molded filament mesh is “fractal” in nature because it is a filament interconnected network at the molecular scale and at the scale of the molded product. The natural tendency of the long molecule filaments to be an entangled structure is maintained.

A method of manufacturing a tampon comprises the steps of at least partially overlaying a web of base material with a web of absorbent material. The web of absorbent material is secured to the web of base material with a first securement. At least one of the web of base material and the web of absorbent material is folded after the first securement. The web of absorbent material is further secured to the web of base material with a second securement that is a stronger securement than the first securement. The web of absorbent material and the web of base material together define a web of cover material. The web of cover material is applied to an absorbent structure. The web of cover material and the absorbent structure is manipulated such that the web of cover material extends about a circumference of the absorbent structure to form a tampon.

An apparatus for compressing a material includes a plurality of levers and a plurality of jaws, wherein each jaw is attached to a lever, and wherein each jaw has a compression surface having an area. The apparatus also includes a compressing mechanism configured to move each lever in a non-linear motion such that the area of a compression surface exposed to the material decreases with the inward movement of that compression surface. Each jaw can be attached to a lever such that a gap is defined between adjacent jaws, the gap having a gap centerline. The compressing mechanism can be configured to move each jaw in a non-linear motion such that the gap centerline of the gap between adjacent jaws is predominantly tangential to an apparatus central longitudinal axis.

An apparatus for producing an absorbent article includes a holding tool, a female tool disposed along a machine axis, and a male tool disposed along the machine axis. The holding tool has an aperture aligned along the machine axis and means for holding a flexible sheet across the aperture. The female tool has at least one folding element extending in a direction radially away from the machine axis, and the male tool has means for holding a fluid storage element and at least one pleating blade extending in a direction radially away from the machine axis. At least two of the holding tool, female tool, and male tool are capable of relative motion along the machine axis. Further the at least one pleating blade and of the male tool and the at least one folding element of the female tool are aligned to permit manipulation of the flexible sheet about the fluid storage element.
摘要:
A novel absorbent tampon suitable for insertion into a body cavity has a substantially elongate, compressed primary absorbent structure having a first end, a second end disposed opposite thereof, and a density of at least about 0.3 g/cm3. The tampon also includes a secondary absorbent structure secured to and extending from the first end of the primary absorbent structure and extending toward the second end of the primary absorbent structure. Preferably, the secondary absorbent structure is disposed about the primary absorbent structure and forms the outer circumferential surface of the tampon. The secondary absorbent structure is capable of extending outwardly from the primary absorbent structure upon the absorption of fluid into the tampon to increase the cross-sectional area of the tampon in the body cavity. In a preferred embodiment, the tampon has sufficient column strength for digital insertion (insertion without an applicator) into a vaginal canal.

摘要:
A process for forming a tampon having a relatively high density, compressed core and a plurality of lower density longitudinal ribs is disclosed. The longitudinal ribs have a softer fiber structure and a coarser capillary structure and extend radially from the core. The process includes forming a fibrous tampon blank, radially pressing a circumferential surface of the blank over spaced apart longitudinally extending portions to form spaced apart ribs, exposing the longitudinal ribs to a radially applied second pressure to form a tampon having a relatively high density, compressed core and a plurality of lower density longitudinal ribs extending therefrom. The longitudinal ribs are separated one from another by outwardly open longitudinal grooves, at least where they extend from the core, and they form a soft, essentially smoothly cylindrical outer surface of the tampon.
