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.

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.

A functionalized microporous, mesoporous, or nanoporous membrane, material, textile, composite, laminate, or the like, and/or a method of making or using such functionalized membranes. The functionalized porous membrane may be a functionalized microporous, mesoporous, or nanoporous membrane that has a functional molecule attached, such as a functional polymer, to the surface and/or internal fibrillar structure of the membrane.

The present disclosure provides a knitted component, the knitted component with a knit element that forms at least a portion of an upper for an article of footwear and defines an interior void for receiving a foot. A lower perimeter edge of the knit element may extend between a lateral side and a medial side of the upper. At least one strand of the knitted component may extend through the lower perimeter edge on opposite sides of the knitted component so as to extend between the lateral side and the medial side of the upper. The knitted component may be formed on a knitting machine, and the at least one strand may be configured to be tensioned to tighten the upper around a last.

A fabric includes base yarns and antistatic spun yarns located in discrete portions of the fabric such that the fabric dissipates static electricity by way of an inductive field and complies with one or more standards for static dissipation in fabric. The antistatic spun yarns may include inductive antistatic staple fibers, and may include less than 20% antistatic fiber. The fabric may be a woven fabric with the antistatic spun yarns inserted into the fabric in both the warp and filling directions in a ratio of antistatic spun yarns to base yarns of from 1:1 to 1:40. The fabrics may be flame resistant and comply with one or more standards for flame resistant fabrics and/or may comply with one or more standards for high visibility apparel. The fabric may have a total antistatic fiber content of less than about 1%.

An expandable support member for an article of footwear includes a plurality of expansion components that are joined together. The support member can be expandable between a contracted position and an expanded position. The plurality of expansion components are configured to expand along a non-linear path when the support member moves between the contracted position and the expanded position.

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

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.

Fabrics made for apparel, tents, sleeping bags and the like, in various composites, constructed such that a combination of substrate layers and insulation layers is configured to provide improved thermal insulation. The fabric composites are constructed to form a radiant barrier against heat loss via radiation and via conduction from a body.
