Abstract: Disclosed are thin, flexible electroluminescent lamps. The lamps comprise bubbles of a light emitting material distributed in a matrix. The bubbles can be formed as voids or transparent shells filled with a light emitting material. The bubbles may also include a conductive material and may be aligned in the matrix. Insulating material may be applied to the lamp's external electrodes to protect the lamp from the environment.

Abstract: An apparatus and process for producing meltblown fibers employs a coflowing primary cold air flow and secondary hot air flow in a meltblowing nozzle. The primary cold air flow provides the majority of the force used to attenuate the polymer stream into fibers, while a secondary hot air flow shrouds the die tip and prevents premature quenching.

Abstract: An electrically activated light emitting cylindrical or other shaped composite filament. A core conductor is optionally surrounded by a first optional insulation layer, surrounded by an outer electrode and an electroluminescent phosphor. The entire assembly may be coated with a second insulation layer. Light is produced by the phosphor when the core conductor and the outer electrode are connected to and energized by an appropriate electrical power supply. The filament may be used to form various one-, two- and three-dimensional light emitting objects.

Abstract: The present invention is directed to a method of forming a heteroconstituent nonwoven web including a mixture of different filament types simultaneously formed into the same web. The filament types may differ as to polymer composition, additive loadings, fiber size, fiber shape, and/or degree of crimping. The invention is also directed to a method of forming a multilayered nonwoven structure in which different filament types constituting different layers are simultaneously formed.
