A product having powder-like properties, the product comprising animal fibres, e.g. wool, having a length less than 10 mm, preferably less than about 3 mm, more preferably less than about 2 mm. Surprisingly, animal fibres having a length below a certain fibre length have powder-like properties, such as improved rheological properties, increased density, increased surface area and increased porosity. Also described are processes for preparing compositions and composites thereof, and uses thereof, e.g., as a filter aid, in a dietary supplement, in a filler and in a hair thickener.

Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.

An electro-optic fiber including a conductive fiber, a layer of electro-optic medium on the conductive fiber, and a conductor on the layer of electro-optic medium. A method of making the electro-optic fiber including the steps of coating a conductive fiber with an electro-optic medium and applying a conductor to the electro-optic medium. The resulting fibers can be woven to create a color-changing material, such as a fabric.

A barrier is provided to be placed between a first region and a second region, to prevent passage of pathogens between the first and second regions. The barrier includes a single ply layer treated with pathogenicidal components. The single ply layer includes a first side directed toward the first region, and includes an outer surface coated with the pathogenicidal components such that pathogens in the first region are incident on the outer surface of the first side. The single ply layer also includes a second side directed toward the second region, and includes an outer surface coated with the pathogenicidal components such that pathogens in the second region are incident on the outer surface of the second side. The pathogenicidal components coated on the outer surfaces of the first and second side deactivate the pathogens incident on the outer surface of the respective first and second sides.

An antiviral fabric including a fabric and an antiviral coating layer which is provided in the fabric and which includes an antiviral fusion protein having an antiviral motif bound to an adhesive protein. The antiviral fabric has excellent processability that enables simple implementation of the antiviral coating layer even on the curved surface of a fiber, the porous surface of a fabric, or a recessed or protruding surface. In addition, the antiviral fabric can have activity persistence that enable maintenance of antiviral activity for a long time without losing the same according to a condition during preparation, storage, use and washing, while having adhesion persistence that enables the maintenance of an adhesive state for a long time after the antiviral coating layer is formed on the surface thereof, and thus can be widely applied to various articles for which fabric is used.

Provided is a method for manufacturing a protection board. A reinforcement fabric including multiple reinforcement fibers is provided, each reinforcement fiber containing multiple adjacent filaments, each filament being composed of a core and a shell formed around the core, and a melting temperature of the shell is lower than a melting temperature of the core, the shell of each filament attached to the shell of the adjacent filament. The impact strength of the shell is higher than the impact strength of the core. The reinforcement fabric can be manufactured into a protection board with good impact resistance simply through heating and molding. Therefore, the reinforcement fabric has the advantage of both manufacturing a protection board with good impact resistance and reducing its process complexity and cost.
