摘要:
A composite material has a foam core having first and second faces. A plurality of fibrous pins have first end portions protruding from the core first face. A first face sheet is secured to the core first face. The first face sheet comprises, in major part, one or more non-woven, non random, fiber layers. The pin first end portions protrude into the first face sheet.

A paper machine for manufacturing textured soft paper comprises a press section with a press nip, through which an impermeable belt and a felt run with the fibrous web between them, a drying cylinder and a transfer roll forming a nip for transfer of the web to the drying cylinder. According to the invention the belt is a texturing belt having a back layer and a web-contacting layer having depressions with surface portions situated between them to form a relief pattern in the web upon passage through the press nip, the texturing belt running from the press to the drying cylinder in order to carry the textured web to the transfer nip. The felt runs away from the texturing belt before a water film formed in the press nip on the texturing belt breaks up. A device is provided before the transfer nip to apply adhesive on the drying cylinder.
摘要:
A low sidestream smoke cigarette comprises a conventional tobacco rod, and a combustible treatment paper having a sidestream smoke treatment composition. The treatment composition comprises in combination, an oxygen storage and donor metal oxide oxidation catalyst and an essentially non-combustible finely divided porous particulate adjunct for said catalyst.
摘要:
A recording paper coated or impregnated with a sizing agent containing a water-soluble soybean polysaccharide as an indispensable component, and optionally a cationic polymer and a surfactant, preferably a nonionic surfactant having HLB of 5-15. The water-soluble soybean polysaccharide is a water-soluble polysaccharide extracted from soybean or soybean extraction residue and subjected to desalinating purification.
摘要:
The invention concerns a method for shielding at least the upper part of a radiocommunication module (1), said module being designed to be transferred on a mother board (5) and including components mounted on a printed circuit and providing at least one of the following functions. RF processing, digital processing and analog processing. The inventive method is characterised in that it comprises the following steps: coating at least the upper part (2) of said radiocommunication module with a resin and adding an electrically conductive layer at the surface of the resin. The invention also concerns a radiocommunication module whereof at least the upper part is thus shielded.
摘要:
A heat-sensitive stencil including a thermoplastic resin film on which a porous resin layer and a porous reinforcing layer are formed in succession. A porous fibrous layer may be disposed between the porous resin layer and the porous reinforcing layer.
摘要:
Thermoplastic fibres of different melting points are present in an aqueous slurry of refractory fibres, binder and flocculant. The slurry is passed through a screen to form a wet body which is heated to dry the body and melt the thermoplastic fibres to bind the refractory fibres together.
摘要:
Described is a micro-structured paper or paper-like material having a self-cleaning and/or non-adhesive effect whereby the paper or paper-like material is hydrophobic across the entire cross-section of the material and which is micro-structured in such a way that the surface is provided with elevations and depressions whereby the distance between the elevations ranges from 0.04 to 100 microns and the height of the elevations ranges from 0.04 to 100 microns, and whereby the paper or paper-like material is characterized in that it contains particles having the size of 0.04 to 50 microns that are bound to the paper or paper-like material by means of a binder, and whereby the paper or paper-like material is hydrophobic across the entire cross section of the material, as well as a method for the production thereof.
摘要:
An anti-slip mat includes three layers, a top and a bottom layer of an expanded, closed cell elastomer and a center layer of a strong, non-stretching and waterproof fabric. The mat layers are held in place, one on top of another, by a fabric binding extending around the perimeter of the map and secured by stitching.
摘要:
Disclosed is a water-disintegratable sheet including water-dispersible fibers and microfibrillated cellulose. The water-dispersible fibers are hydroentangled about each other to provide high fiber density regions and low fiber density regions. The hydroentangled water-dispersible fibers are bonded to each other through a hydrogen bonding power of the microfibrillated cellulose.
