| 20080291093 | NON-WOVEN TEXTILE MICROWAVE PATCH ANTENNAS AND COMPONENTS - A microwave patch antenna comprising: a plurality of conductive antenna patterns; a plurality of groundplanes; a plurality of feed elements; a plurality of feed slots to allow feed elements to pass through the non-woven dielectric spacers; and a plurality of dielectric separator layers comprised of corrugated non-woven fabric as necessary to form a patch antenna construction. | 11-27-2008 |
| 20090017708 | LIGHTWEIGHT HIGH-TENSILE, HIGH-TEAR STRENGTH BIOCOMPONENT NONWOVEN FABRICS - A method of producing a nonwoven fabric comprising spinning a set of bicomponent fibers which include an external fiber component and an internal fiber component. The external fiber enwraps said internal fiber and has a higher elongation to break value than the internal fiber and a lower melting temperature than the internal fiber component. The set of bicomponent fibers are positioned onto a web and thermally bonded to produce a nonwoven fabric. | 01-15-2009 |
| 20090042475 | MIXED FIBERS AND NONWOVEN FABRICS MADE FROM THE SAME - The subject matter disclosed herein relates generally to the production of a predetermined ratio of multicomponent fibers in combination with monocomponent fibers or other multicomponent fibers, preferably through a spunbonding process. After extrusion, these fibers can produce a fiber network that is subsequently bonded to produce a nonwoven fabric comprising multiple types of fibers. The multicomponent fibers within the network may be processed to remove one component by dissolution or to split the individual components into separate fibers. As a result, the fabric will be comprised of fibers with a range of diameters (micro- or nano-denier fibers as well as higher denier fibers) such that the fibers will not pack as tightly as in a homogeneous nonwoven fabric produced from one type of monocomponent or multicomponent fiber. The present invention additionally relates to methods for producing nonwoven fabrics with increased loft, breathability, strength, compressive properties, and filtration efficiency. | 02-12-2009 |
| 20090258559 | STAPLE FIBER DURABLE NONWOVEN FABRICS - The invention provides durable nonwoven fabrics comprising staple fibers. Methods of preparing durable nonwoven fabrics based on staple fibers are also provided. The methods can include the steps of at least one of needle punching and hydroentangling. The durable nonwoven fabric can be subjected to additional bonding techniques, such as resin bonding and/or thermal bonding. The durable nonwoven fabrics of the invention provide improved durability over conventional nonwoven fabrics. Further advantages of the inventive nonwoven fabrics include maintaining the smooth surface qualities of the fabric and desirable feel of the fabric even with the enhanced durability. The inventive nonwoven fabrics can also be subjected to additional post-processing techniques that conventional nonwoven fabrics would otherwise be unable to withstand. Further, inks and/or dyes can more readily become adhered to the smooth nature of the surfaces of the inventive durable nonwoven fabrics. | 10-15-2009 |
| 20090286055 | Methods and Devices for Providing Flexible Electronics - Methods and devices for providing flexible electronics are described. In an exemplary embodiment of the present invention, a conductive ink is applied to a nonwoven substrate. More particularly, the exemplary embodiment provides a nonwoven substrate with a general depth in the z-direction and a conductive ink carried by the nonwoven substrate on the surface of the substrate and at least partially but no more than 50% within the nonwoven substrate in the z-direction. | 11-19-2009 |

| 20110318986 | MICRO AND NANOFIBER NONWOVEN SPUNBONDED FABRIC - The invention provides methods for the preparation of nonwoven spunbonded fabrics and various materials prepared using such spunbonded fabrics. The method generally comprises extruding multicomponent fibers having an islands in the sea configuration such that upon removal of the sea component, the island components remain as micro- and nanofibers. The method further comprises mechanically entangling the multicomponent fibers to provide a nonwoven spunbonded fabric exhibiting superior strength and durability without the need for thermal bonding. | 12-29-2011 |
| 20120015020 | BIODEGRADABLE DRUG OR OTHER ACTIVE DELIVERY SYSTEM - A nonwoven fabric has been developed as a delivery system for drugs or other actives which includes biodegradable and biocompatible fibers with plant virus nanoparticles. The plant virus nanoparticles are pre-loaded with one or more actives. | 01-19-2012 |
