Description

BACKGROUND OF THE INVENTION 1. Technical Field This invention relates generally to textile sleeves for protecting elongate members, and more particularly to flexible, circumferentially continuous, seamless textile sleeves having arc resistant, abrasion resistant, heat resistant and fluid repellent properties. 2. Related Art It is known to contain and protect elongate members, such as wires and wire harnesses, for example, in circumferentially continuous, tubular textile sleeves to provide protection to the cables, wires, and hoses. However, these sleeves typically have multiple layers, with each of the layers being specifically provided for a different type of protection. Although the aforementioned multilayer sleeves may provide suitable protection against various environmental conditions, unfortunately they are bulky, having a thick, multilayered wall with different types of yarns being provided in each layer, thereby requiring an increased volume of space, and further, they tend to be relatively heavy and exhibit low flexibility. Further yet, having to include multiple layers can prove problematic in some applications, particularly applications requiring routing cables, wires or hoses through tight, winding areas, as well as applications having weight restrictions, such as aircraft and aerospace applications, for example. SUMMARY OF THE INVENTION One aspect of the invention provides a textile sleeve for routing and protecting an elongate member. The textile sleeve includes a circumferentially continuous, seamless wall. The circumferentially continuous, seamless s wall includes a textile layer having an outer surface and an opposite inner surface bounding an enclosed cavity extending lengthwise along a central longitudinal axis between opposite open ends. The textile layer is formed of yarns interlaced with one another, wherein at least some of the yarns include multifilaments resistant to heat and monofilaments resistant to heat, and a silicone-based coating adhered to the outer surface of the textile layer. In accordance with another aspect of the invention, the yarns can including warp yarns extending generally parallel to the central longitudinal axis and weft yarns extending generally transversely to the central longitudinal axis, with the warp yarns being woven with the weft yarns. In accordance with another aspect of the invention, the warp yarns can be provided entirely from multifilaments resistant to heat and the weft yarns can be provided including monofilaments resistant to heat. In accordance with another aspect of the invention, the weft yarns can be provided including monofilaments resistant to heat and multifilaments resistant to heat. In accordance with another aspect of the invention, the multifilaments resistant to heat can be provided as meta-aramid. In accordance with another aspect of the invention, the warp multifilaments resistant to heat can be provided having a denier between about 100-3000 and the weft multifilaments resistant to heat can be provided having a denier between about 50-1000. In accordance with another aspect of the invention, the monofilaments resistant to heat can be provided having a diameter between about 0.1-0.5 mm. In accordance with another aspect of the invention, the monofilaments resistant to heat can be provided as PEEK. In accordance with another aspect of the invention, the silicone-based coating can include at least one, or both of a flame retardant and a heat stabilizer. In accordance with another aspect of the invention, the silicone-based coating has a thickness between about 0.1-3.0 mm. In accordance with another aspect of the invention, the textile layer is circumferentially continuous and seamless. In accordance with another aspect of the invention, the textile layer has opposite edges extending lengthwise between the opposite open ends, with the opposite edges being in overlapped relation with one another, with a seam formed between the overlapped edges, wherein the silicone-based coating is circumferentially continuous and seamless to close off the seam between the overlapped opposite edges. In accordance with another aspect of the invention, a method of constructing a wrappable sleeve for routing and protecting an elongate member from arcing, exposure to abrasion, thermal conditions including high heat and fire, fluid (water/fuel) ingress, and other environmental conditions, such as contamination, and to protect against fluid absorption into a wall of the wrappable sleeve, is provided. The method includes interlacing heat-resistant yarn to form a textile layer having an outer surface and an inner surface bounding a cavity extending lengthwise along a central longitudinal axis between opposite open ends. Further, bonding a silicone-based coating on an outer surface of the textile layer such that the silicone-based coating is circumferentially continuous and seamless along the length of the textile layer. In accordance with another aspect of the
