Methods for increasing biocidal activity of a substrate are provided. The methods can include attaching one or more ionic compounds to the substrate. The ionic compound can include a cationic moiety and at least one of an N-halamine precursor group or an N-halamine moiety.

Dimensionally stable open woven fabrics formed from a plurality of high tenacity warp elongate bodies interwoven and bonded with a plurality of transversely disposed, high tenacity weft elongate bodies, composite articles formed therefrom, and to a continuous process for forming the composite articles.

A wrappable textile sleeve with closure system and method of construction is provided. The sleeve has a wall of interlaced yarn with opposite edges extending in a lengthwise direction along a longitudinal axis between opposite ends. The opposite edges are wrappable into overlapping relation with one another to form a tubular cavity. The wall has a first set of closed loops positioned adjacent one of the opposite edges and a second set of closed loops positioned adjacent the other of the opposite edges. At least one flexible lace is disposed through the closed loops in a zig-zag pattern, thereby extending back-and-forth between the first set of loops and the second set of loops. The flexible lace is slidable through the plurality of loops to facilitate drawing and maintaining the opposite edges in overlapping relation with one another.

Certain embodiments are directed to cyanate resin blends comprising, for example, a mixture of a cyanate monomer and a cyanate oligomer. The resin blends are effective to provide a dielectric constant of less than 2.7, a glass transition temperature of at least 150 C. and a moisture absorption of less than 1.5%. Radomes using the resin are also described.

A high-quality multilayer thermoplastic-resin-reinforced sheet material having excellent mechanical properties and drapeability in which a thermoplastic resin excellent in recycling efficiency and shock resistance is used as a matrix. A thermoplastic-resin multilayer reinforced molding formed of the multilayer thermoplastic-resin-reinforced sheet material, in which the high quality and the mechanical properties are maintained. The multilayer thermoplastic-resin-reinforced sheet material (11) is formed by stacking thermoplastic-resin-reinforced sheet materials (21A) to (21D) each formed of a reinforcing-fiber sheet material (31), consisting of a plurality of reinforcing fibers (31f) arranged in a predetermined direction in a sheet-like structure, and a thermoplastic-resin sheet material (41) joined to a surface of the reinforcing-fiber sheet material (31), and stitching them together with an integration thermoplastic-resin fiber tow (51) composed of the same material as the thermoplastic-resin sheet material (41). The reinforcing-fiber sheet materials (31) are stacked such that their reinforcing directions are multiaxial.

Disclosed herein are polyesters and fibers made therefrom. The fiber comprises a polymer, poly(trimethylene furandicarboxylate) (PTF), and PTF based copolymers.

Fabrics containing camouflage patterns are produced from dyes wherein at least certain of the colors contained in the pattern contain a low reflectance dye. The low reflectance dye is added to one or more colors in the pattern in order to preserve the camouflage pattern when viewed through night vision goggles as relatively long wavelengths, such at wavelengths greater than 900 nm. In one embodiment, the low reflectance dye comprises a thiazine. The low reflectance dye is blended with other dyes to produce colors in the pattern. By altering the concentration of the low reflectance dye in each of the colors, the colors contained in the camouflage pattern remain separate and distinct even at relatively long wavelengths.

A joint tape for drywall includes a substrate layer having an elongate shape in a lengthwise direction and being flexible in the lengthwise direction and in a transverse direction. The tape further includes a covering layer disposed in bonding relation on the substrate layer. The covering layer is rigid in the transverse direction and configured to withstand compressive forces applied generally in the transverse direction and shear stresses applied generally along the transverse direction.

An apparel item configured to reduce the perception of cling is provided herein. The apparel item comprises a first set of outwardly-projecting nodes on a first portion of the apparel item, a second set of outwardly-projecting nodes on a second portion of the apparel item, and a third set of inwardly-projecting nodes on a third portion of the apparel item, where the third set of nodes is positioned between the first set of nodes and the second set of nodes. The first and second sets of outwardly-projecting nodes comprise apertures that provide a communication passage from an outer surface of the apparel item to an inner surface of the apparel item. Besides reducing the surface area of the apparel item that comes into contact with a wearer's skin surface, the nodes also facilitate cooling the wearer and speed up drying times of the apparel item when being worn.

The present disclosure provides novel poly(phenylene ethynylene) (PPE) compounds, methods for synthesizing these compounds, and materials and substances incorporating these compounds. The various PPEs show antibacterial, antiviral and antifungal activity.
