Nonwoven web products containing sub-micron fibers, and more specifically nonwoven web products having sub-micron fibers formed by fibrillation of polymer films, and nonwoven materials and articles incorporating them, and methods of producing these products.

Nonwovens and articles containing submicron fibers

Processes for producing nonwoven web products containing sub-micron fibers are provided, and more specifically processes for producing nonwoven web products having sub-micron fibers formed by fibrillation of polymer films are provided.

Process for producing nonwovens and articles containing submicron fibers

An apparatus for producing sub-micron fibers, and more specifically an apparatus for effecting formation of sub-micron fibers by fibrillation of polymer films, and nonwoven materials and articles incorporating them.

Apparatus for producing sub-micron fibers, and nonwovens and articles containing same

Apparatus () and die cartridge assembly () adapted for use with same for producing fibrous material (). The apparatus () comprises a removably attachable die cartridge assembly () that adapts to conventional spunmelt equipment. The die cartridge assembly () is removably positionable beneath an extrusion body () for effecting formation of fibrous material by fibrillation of polymer films. The cartridge assembly () includes at least one polymer passage () communicating with a molten polymer source () for directing molten polymer onto at least one film forming surface () defined by the cartridge assembly (), and also defines at least one gas passage () communicating with a gas source () for directing pressurized gas () against the molten polymer () in the form of a film for effecting formation of the fibrous material ().

Apparatus and die cartridge assembly adapted for use therewith, and process for producing fibrous materials

A process and apparatus for producing sub-micron fibers, and more specifically a process and apparatus for effecting formation of sub-micron fibers by fibrillation of polymer films, and nonwoven materials and articles incorporating them.
