A process for producing a fleece having metallic wire filaments, includes at least the following steps:a) forming a layer including wire filaments;b) producing first cohesive connections between at least some of the metallic wire filaments in a first joining process; andc) producing second cohesive connections between metallic wire filaments in a second joining process. A process for producing a honeycomb body having at least one fleece, a fleece, a honeycomb body, an apparatus and a vehicle using fleeces in the treatment of exhaust gas from motor vehicles, are also provided.
摘要:
A method and system for aligning nanotubes within an extensible structure such as a yarn or non-woven sheet. The method includes providing an extensible structure having non-aligned nanotubes, adding a chemical mixture to the extensible structure so as to wet the extensible structure, and stretching the extensible structure so as to substantially align the nanotubes within the extensible structure. The system can include opposing rollers around which an extensible structure may be wrapped, mechanisms to rotate the rollers independently or away from one another as they rotate to stretch the extensible structure, and a reservoir from which a chemical mixture may be dispensed to wet the extensible structure to help in the stretching process.
摘要:
Reinforcing fibers with small particles having a longest average dimension of approximately 0.01 nanometer to approximately 30 micrometers physically and/or chemically bonded directly to their surfaces to form protuberances thereon and a method and system for making these modified fibers are disclosed. The particles directly bonded to the surfaces of the fibers, serve to enhance physical properties of composite articles which incorporate such fibers as reinforcement.
摘要:
The present invention provides a metallic fiber nonwoven fabric manufacturing apparatus mainly including a metallic fiber manufacturing apparatus (7), an ejection nozzle heater (5), a metallic fiber flying apparatus (6), a nonwoven fabric surface density control mechanism, a method for manufacturing an aluminum fiber fabric by using the metallic fiber nonwoven fabric manufacturing apparatus, and a method for manufacturing a laminated aluminum material. By using the metallic fiber nonwoven fabric manufacturing apparatus, manufacture of a high-quality metallic fiber nonwoven fabric and manufacture of an aluminum fiber nonwoven fabric are possible. Further, manufacture of a laminated aluminum material is also possible.
摘要:
The present invention relates to a method of making a scouring web. The method of making the scouring web comprises providing a plurality of metal fibers and a plurality of polymeric fibers, combining the metal fibers with the polymeric fibers, heating the polymeric fibers so that at least a portion of the polymeric fibers melt, and cooling the polymeric fibers to solidify the portion of the polymeric fibers that melted and to secure the blend of metal fibers and polymeric fibers together.
摘要:
A curable aqueous composition including (a) a polyacid including at least two carboxylic acid groups, anhydride groups, or salts thereof; (b) a polyol including at least two hydroxyl groups; and (c) an emulsion polymer including, as copolymerized units, greater than 30% by weight, based on the weight of the emulsion polymer solids, ethylenically unsaturated acrylic monomer including a C5 or greater alkyl group; wherein the ratio of the number of equivalents of the carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of the hydroxyl groups is from 1/0.01 to 1/3, and wherein the carboxylic acid groups, anhydride groups, or salts thereof are neutralized to an extent of less than 35% with a fixed base is provided. Also provided is a method for treating heat-resistant fibers or a heat-resistant nonwoven formed therefrom with the curable aqueous composition and the article prepared thereby.
