摘要:
Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.

Die Erfindung bezieht sich auf einen beschichteten Festigkeitsträger, ein Verfahren zu dessen Herstellung und Verwendung. Um einen beschichteten Festigkeitsträger, insbesondere für die Anwendung für großflächige Bauteile bereitzustellen, dessen Beschichtung im Wesentlichen unabhängig von den verarbeitungsrelevanten Gegebenheiten der Komponenten der Harzmischung einfach und unkompliziert aufgebracht werden kann, wird vorgeschlagen, dass die Oberfläche des Festigkeitsträgers eine Beschichtung aus einer Zusammensetzung aufweist, die Zusammensetzung eine Mischung 1 aus zumindest einem Harz ausgewählt aus der Gruppe der epoxidierten Phenolnovolake, epoxidierten Kresolnovolake, Polyepoxide auf der Basis von Bisphenol-A, epoxidierten Fluorenonbisphenole und/oder Polyepoxiden auf der Basis von Bisphenol-F, und/oder auf der Basis von Triglycidylisocyanuraten, epoxidierten Novolak und zumindest einer die Härtung des Harzes beschleunigende Komponente enthält und diese Mischung einer Wärmebehandlung unterzogen wird, so dass die Mischung 1 auf der Oberfläche des Festigkeitsträgers durch Aufschmelzen fixiert ist.

An electroconductive textile comprising: a non-conductive textile such as a wool-containing fabric, a macromolecular template which is bonded to or entrapped in the non-conductive textile such as poly 2-methoxyaniline-5-sulfonic acid (PMAS), and a conductive polymer which is ordered by and bonded to the macromolecular template such as polyaniline; in which the macromolecular template binds the conductive polymer to the non-conductive textile.
摘要:
A method for preparing a fabric substantially consisting of carbon fibres for impregnation with a thermoplastic plastic comprises of:
a) providing a fabric which substantially consists of carbon fibres with a coating of an epoxy material without curer; and (b) bringing and for a chosen time holding this fabric at an increased temperature such that the carbon fibres remain unaffected and the epoxy material is aged or neutralized and loses its tacky character.
摘要:
The present invention includes novel barrier webs that have certain desirable physical qualities such as water resistance, increased durability, improved barrier qualities and the like. The present invention further comprises a barrier web comprising a web that has been treated with a curable shear thinned thixotropic polymer composition, the fabric being adapted to be substantially impermeable to liquids, permeable to gases and impermeable to microorganisms. The barrier webs of the present invention are either impermeable to all microorganisms or are impermeable to microorganisms of certain sizes. The present invention also includes fabrics that are capable of either selective binding certain microorganisms, particles or molecules depending upon what binding partners are incorporated into the polymer before application to the fabric.
摘要:
Disclosed is a method of coating a permeable sheet with amphiphilic proteins, the method including the steps of: 1) providing a permeable sheet having a plurality of individual exposed surfaces, at least a portion of which having relatively low surface energies; 2) providing an aqueous solution containing amphiphilic proteins, the solution having a relatively high surface tension; and 3)contacting the solution containing amphiphilic proteins under shear stress conditions with the matrix of fibrous material so that at least a portion of the amphiphilic proteins are adsorbed onto at least some individual exposed surfaces. Also disclosed is a protein-coated permeable sheet composed of: 1) a permeable sheet having a plurality of individual exposed surfaces, at least a portion of which having relatively low surface energies; and 2) amphiphilic proteins adsorbed onto at least some individual exposed surfaces to define a gradient distribution of amphiphilic protein coating along at least one dimension of the permeable sheet.
