A process and system are provided for introducing a blend of chopped and dispersed fibers on an automated production line amenable for inclusion in molding compositions as a blended fiber mat for structural applications. The blend of fibers are simultaneously supplied to an automated cutting machine illustratively including a rotary blade chopper disposed above a vortex supporting chamber. The blend of chopped fibers and binder form a chopped mat. The chopped mat has a veil mat placed on either side, and is consolidated with the veil mat using heated rollers maintained at the softening temperature of thermoplastic binder, with consolidated mats being amenable to being stored in rolls or as flat sheets. A charge pattern is made using the consolidated mat, and the charge pattern can be compression molded in a mold maintained at a temperature lower than the melting point of the thermoplastic fibers.

Methods for the treatment of textiles used for facial masks assure for the inactivation of viruses captured by the textile. The aerosol droplets are absorbed by the textile, and any viruses in the water droplets react with a virucidal substance. The surface of textile fibers is first exposed to gaseous plasma to assure appropriate wettability. The textile is then soaked in a diluted water solution of a virucidal substance. The excessive water solution is optionally removed by draining, and the drained textile is then dried. The methods enable uniform coating of the textile fibers with an extremely thin film of virucidal substance. A typical concentration of the virucidal substance in the textiles treated according to the methods of the aspects of disclosed embodiments is about 10 g/kg. Such a small concentration is benign to humans but effectively inactivates the viruses that might be captured by the textile.

A molding method is performed for molding a composite material in which resin is injected in a state in which a fiber base material is disposed in a cavity formed in a metal mold and the resin is cured to form the composite material. The molding method includes enhancing wettability of a portion of the fiber base material, and disposing the portion of the fiber base material in a narrow portion in which a gap constituting the cavity is smaller than other locations.

This invention relates to a method for hiding stains in medical dressings and other textile substrates. The method includes applying a metallic silver coating to a textile substrate via a plasma enhanced chemical vapor deposition (PECVP) process. The metallic silver coating effectively hides any stain that comes into direct contact with the treated substrate by transferring the liquid beneath the surface of the coating. The invention also relates to textile substrates containing metallic silver coatings.

A blowable insulation material comprising natural fibers and short cut synthetic fibers or fiber balls. The natural fibers and short cut synthetic fibers or fiber balls are individually treated with a water repellent to impart water repellency to the fibers, and later aerodynamically blended together. The water repellent fibers constitute a part or most of the blowable insulation material, thus enhancing the durability of the structure as well as water repellency, which may be advantageous during washing or laundering.

The present invention relates to surface-modified polyolefin fibers, the use of these fibers in hydraulic binder compositions, hydraulic binder compositions containing these fibers and a method for reinforcing hydraulic binder compositions.

Provided is a polymeric material having a micro-nano composite structure, a device including the same, and a method of manufacturing the polymeric material. The polymeric material includes a polymer fiber or film, wherein the polymer fiber or film has, on a surface thereof, a micro-nano composite structure including a microstructure containing concavo-convex grooves having a microscale semi-cylindrical shape () and a nanopattern containing nanoscale protrusions formed on a surface of the microstructure. The polymeric material has excellent absorbency and hydrophilic or super-hydrophilic surface properties, and also has oleophobic or super-oleophilic properties in water, and thus may be effectively applied to fields such as oil-water separation, purification, and filters. The polymeric material may be readily manufactured through an environmentally friendly, large-area atmospheric pressure plasma process.

An apparatus for depositing a polymer layer containing nanomaterial on a substrate material includes a carrier for carrying the substrate material; a transport structure for providing a polymerization material near a surface of the substrate material and conducting a gas flow near the surface of the substrate material with the gas flow comprising a nanomaterial; and a plasma chamber wherein a plasma electrode structure is arranged for depositing the polymer layer containing nanomaterial on the surface of the substrate material by applying a plasma polymerization process.

Polymeric materials are described which have a bioflavonoid coating, the bioflavonoid content of the coating comprising at least naringin and neohesperidin. The use of such coated polymeric materials is also described as well as the process for making the coated polymeric materials.

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.
