A self-wrapping textile sleeve that is abrasion, arc and water resistant and method of construction thereof is provided. The sleeve includes a wall having opposite edges extending in a lengthwise direction along a central longitudinal axis of the sleeve between opposite ends. The opposite edges overlap one another to form an inner tubular cavity. The wall has warp yarns extending in the lengthwise direction generally parallel to the central longitudinal axis and weft yarns extending generally transversely to the longitudinal axis between the opposite edges. The warp and weft yarns include expanded PTFE yarns, and the weft yarns further include heat-settable thermoplastic yarns. The heat-settable polymeric yarns impart a bias on the wall to bring the opposite edges into their overlapping relation.

An object of the present disclosure is to provide an actuator having even better durability than the conventional actuator. Specifically, an actuator has an actuator main body constituted of a cylindrical tube capable of expanding/contracting by hydraulic pressure and a sleeve for covering an outer peripheral surface of the tube, the sleeve having a cylindrical structure formed by cords woven to be disposed in predetermined directions, wherein: the inner diameter r.sub.0 (mm) of the tube, the thickness t (mm) of the tube, the storage elastic modulus E′ (MPa) of the tube at 25° C., and the mesh aperture ratio A of the cords constituting the sleeve in a pressurized state satisfy the following formula (1):

50≤E′×(t/r.sub.0)/A≤600   (1)

A flexible innerduct structure having a first edge, a second edge, a first margin region, a second margin region, and a middle region. The middle region is located between the first and second margin regions. The innerduct structure comprises at least two flexible longitudinal tubes, each longitudinal tube forming two chambers. Each chamber is designed for enveloping at least one cable, where at least one of the longitudinal tubes extends from the first margin region to the second margin region, and wherein the tubes are attached together at an attachment in the middle region.

Aspects herein are directed to a tubular knit sleeve for a below-the-knee amputee where the tubular knit sleeve includes zoned grip features, zoned cushioning features, zoned traction features, and zoned breathability/permeability features that facilitate the wearer participating in athletic activities, such as wrestling, without a prosthetic leg.

A tubular woven fabric is useful as a transport hose for a fluid or a powder, as a protective hose for linear bodies such as wires, cables and conduits, as a tubular filter, or as a base material of a vascular prosthesis. The tubular woven fabric includes warp yarns and weft yarns interwoven with each other, the tubular woven fabric having an outer diameter with a variation of within 10% along the warp direction and satisfying the formula:
(L2−L1)/L1≤0.1.

A woven sleeve and method of construction are provided. The sleeve (10,10′) has a flexible, abrasion resistant elongate wall (12,12′) constructed from woven monofilament and/or multifilament yarns. The wall is configured to bound a cavity extending along a central axis (18) of the sleeve. The wall is woven with warp yarns (23) that extend generally parallel to the central axis of the sleeve and fill yarns (24) that extend circumferentially about the sleeve, generally transversely to the central axis. The warp yarns are bundled into individual, discrete groups (22), with each group (22) including a plurality of yarns (23) in side-by-side relation with one another, wherein each of the yarns (23) within the same discrete group (22) is interlaced over the same side of a common fill yarn (24).

The sheath forms, in the mounted state, a flexible tubular casing configured to receive the cable.

The sheath includes comprises elongated elements such as wires or strips, which include elongated elements of a first type, made of at least one electrically conductive material; and elongated elements of a second type, different from the first type, made of at least one material having sufficient magnetic properties to produce the shielding effect. The elongated elements are assembled in a crisscross manner and/or forming an encircling, and the sheath is produced in the form of an initially substantially flat sheet, suitable for being wound around the cable.

An end fray resistant textile sleeve includes an elongate wall having warp yarns extending generally parallel to a longitudinal central axis of the sleeve and fill yarns extending circumferentially about the sleeve. The warp yarns include at least two different types of yarns, with one of the types of warp yarns including activateable yarns and another of the types of yarns including non-activateable yarns. The activateable yarns can be provided as being activateable by at least one of heat, fluid and/or pressure, such that upon being activated, the yarns are caused to bond with the adjacent non-activateable warp yarns, as well as with the weft yarns with which they make contact. As such, the activateable yarns, upon being activated, become fixed with abutting warp yarns and weft yarns, thereby inhibiting end fray from resulting during a subsequent cold-cutting operation as well as in use.

A wrappable textile sleeve and method of construction thereof is provided. The textile sleeve includes an elongate wall extending along a longitudinal axis between opposite ends with lengthwise extending edges extending along the longitudinal axis between the opposite ends. The wall is woven from lengthwise extending warp yarns and circumferentially extending weft yarns with at least some of the weft yarns being heat-set to impart a self curling bias on the wall to bring the edges into overlapping relation with one another. Further, the weft yarns form a plurality of discrete annular bands that extend circumferentially about the longitudinal axis with adjacent bands having different picks-per-inch from one another to provide the sleeve with enhance regions of flexibility, self-curling bias and hoop strength.

A textile sleeve for routing and protecting an elongate member has a wall including a textile layer with an inner surface and an opposite outer surface extending lengthwise along a central longitudinal axis between opposite ends. The inner surface is configured to bound a cavity sized for receipt of the elongate member therein. The textile layer is formed of yarns interlaced with one another, wherein a least some of the yarns include multifilaments resistant to heat and/or monofilaments resistant to heat, rendering the sleeve heat-resistant. A silicone-based coating is adhered to the outer surface to provide enhanced heat-resistance, dielectric protection and impact resistance.
