International Classification:

B05D 1/14
B05D 1/38

US Classification:

427464, 427462, 427470, 427115

Abstract:

A method is provided for the fabrication of a fibrous structure. Fibers are deposited in a hopper connected to an electrode. A mesh covers the hopper opening and the hopper is inverted and suspended over an adhesive coated substrate. An electric field is generated between the hopper and the substrate while the hopper is simultaneously shaken. As a result, fibers fall through the mesh, aligned along the electric field lines, travel through the electric field, and are coupled on one end thereof to the adhesive.

US Classification:

442135, 442304, 442318, 66192, 66195, 42106, 473421

Abstract:

The invention provides methods for finishing knitted fabrics and fabrics finished by the novel process. In one embodiment, the method of finishing a knitted fabric includes the steps of: (a) stretching the fabric above about 5% but less than about 25% in width, and above about (−)7% but less than about 10% in length, (b) heat-setting the fabric to the stretched width and length at a temperature above about 120 degrees Centigrade and lower than about 250 degrees Centigrade, and (c) applying a polymeric protective binder coating resin to the fabric at a concentration of at least 5% but less than 25% based on the weight of the fabric.

International Classification:

B32B 5/08
B32B 5/12

US Classification:

428 86, 428119, 428 90

Abstract:

Fiber based z-directional reinforced composites having enhanced inter-laminar strength, impact toughness, transmission properties (electrical and thermal conduction) and coefficient of thermal expansion are provided. The composites include at least two substrates separated by a reinforcement zone that includes a plurality of fibers disposed in a binder resin. At least some, and in one embodiment, a majority, of the fibers are oriented so as to be substantially perpendicular to the substrates. Multi-layered composites having more than two substrate layers can also be formed. Methods for forming such composites are also provided.

US Classification:

428596, 442320, 428 90, 428 92, 428 361

Abstract:

Flocked textile materials are disclosed as a support media for bacteria that actively biochemically convert noxious chemical species. Flocked fibrous netting materials as bioconversion support media are favorable to biological growth and provide excellent liquid (e.g. wastewater) flow through its structure as well as accommodating aeration processes. The disclosed support materials can be geometrically designed and positioned in many ways including stacked sheets/plies, rolled sheets in single or multi-walled tubes, and continuous belts or webs that can be self-cleaning and configured to operate in an automated process control mode. The disclosed support media facilitate development of compact and durable biofilter structures at a low cost.
