摘要:
A functional sheet is coated with physically vapor-deposited film including titanium oxide and other metallic oxides for making the film transparent so color and pattern on the fiber sheet are visible, providing electric conductivity to the film, improving the productivity of vapor deposition and enabling selective blocking of infrared and ultraviolet radiation.
摘要:
Compositions suitable for fibers have been discovered that faciliate unwinding of the fibers. The compositions typically comprise an ethylene/α-olefin interpolymer and a fatty acid amide comprising from about 25 to about 45 carbon atoms per molecule. The compositions may be made into fibers useful for knit or woven fabrics.
摘要:
A complex-shaped, three-dimensional fiber reinforced composite structure may be formed by using counteracting pressures applied to a structural lay-up of fiber plies. The fiber plies are arranged on a pressurizable member that may become an integral part of the final product, or may be removed before the product is finalized. The pressurizable member may take the form of a hollow blow molded or rotomolded thermoplastic component or a superplastic formed metallic component having an opening such that the pressurizable member may be vented or pressurized and thus expanded against the fiber plies. In addition, a number of the pressurizable members may be joined in fluid communication, where they may each have different configurations, yet be arranged to form a large, complex-shaped lay-up surface for the fiber plies. The arrangement of the fiber plies onto the pressurizable members may produce integral I-Beam stiffeners, ribs, flanges, and other complex shaped structural components.
摘要:
The present invention relates generally to substrates that exhibit useful, auto adaptable surface energy properties that depend on the environment of the substrate. Such surface energy properties provide relatively high advancing and receding contact angles for liquids when in contact with the target substrate surface. The substrates exhibit low surface energy quantities of at most about 20 millijoules per square meter (mJ/m2) at a temperature of about 25 degrees C. and a surface energy greater than about 20 mJ/m2 at, or with exposure to, a temperature of about 40 degrees C. More specifically, encompassed within the present invention are textile substrates having this highly desirable unique surface energy modification property and which exhibit wash durable oil and water repellency and stain release features. Novel compositions and formulations that impart such surface energy modifications to substrates are also encompassed within this invention, as well as methods for producing such treated substrates.

摘要:
A porous carbon base material includes a sheet containing carbon short fibers dispersed randomly and a carbonized resin, in which the carbon short fibers are bound by the carbonized resin and the volume of pores having a pore diameter of 10 μm or less is 0.05 to 0.16 cc/g. A method for producing this porous carbon base material includes intermittently transporting a precursor fiber sheet including short carbon fibers dispersed randomly and a resin to a space between heated plates, subjecting the precursor to a heating and pressuring treatment by the heated plates while the transformation stops, carrying out the transportation of the sheet after the treatment, and then carrying out a heat treatment, to thereby carbonize the resin in the sheet.
摘要:
An apparatus for making an elastic laminate including a crosslinked elastic layer formed of an elastic copolymer includes a die for extruding a layer of crosslinkable elastic copolymer, at least one roll for conveying the elastic layer, a supply source for providing at least one nonwoven web, a lamination nip for laminating at least one nonwoven web to the elastic layer, a processing unit for crosslinking the elastic layer and a winder for collecting the elastic laminate. The crosslinkable elastic copolymer may be a crosslinkable elastic styrenic block copolymer, a crosslinkable semi-crystalline polyolefin plastomer, or a crosslinkable propylene-ethylene copolymer. The crosslinkable elastic layer may be extruded in the form of a plurality of parallel filaments such as by a filament die. The processing unit may be positioned between the at least one roll and the lamination nip or may be positioned between the lamination nip and the winder. The processing unit may have an open or a closed configuration and may be an electron beam processing unit.

A convertible roofing material which includes an outer fabric layer formed at least partially of polymeric coated, core yarns such as a polyester core coated with polyvinyl chloride.
摘要:
A roofing underlayment having a slip-resistant surface includes a woven polypropylene scrim laminated to a top layer made from a non-woven spun-bond polypropylene fabric. During lamination, the scrim is bonded to the top layer by a polypropylene coating that impregnates the scrim, thereby forming a structural bottom layer comprising the polypropylene-impregnated scrim. The non-woven fibers of the top layer provide a micro-textured, slip-resistant surface. A second polypropylene coating may be applied to the bottom surface of the bottom structural layer. An adhesive layer may optionally be applied either to the bottom surface of the bottom structural layer, or, if used, to the bottom surface of the second polypropylene coating.
