Abstract

A self-wrapping, textile sleeve for routing and protecting elongate members from exposure to abrasion, thermal and other environmental conditions and method on construction thereof. The sleeve has an elongate wall constructed from interlaced yarns having interstices between adjacent yarns. At least one of the yarns is heat formed at one temperature to form the wall as a self-wrapping wall curling about a longitudinal axis of the sleeve. The wall has an inner surface providing a generally tubular cavity in which the elongate members are received. The wall also has an outer surface with a cured layer thereon. The cured layer is cured at the one temperature at which the yarns are heat formed into their self-wrapping configuration, wherein the cured layer fills the interstices between adjunct yarns to form an impervious layer on the wall.

Claims (12)

1. A method of constructing a self-wrapping, textile sleeve for routing and protecting elongate members, comprising:

forming an interlaced textile wall having interstices extending between opposite outer and inner surfaces;

applying a liquid coating to the entirety of the outer surface;

heat forming the wall into a self-wrapping configuration at one temperature with the inner surface providing a tubular cavity; and

curing the liquid coating at the one temperature during the heat forming step.

2. The method of claim 1 further including converting the liquid coating to form an impervious layer on the outer surface during the curing step.

3. The method of claim 2 further including filling the interstices with the impervious layer and forming the impervious layer on the inner surface.

4. The method of claim 2 further including leaving the inner surface substantially free of said impervious layer.

5. The method of claim 1 further including providing the liquid coating as a fluorocarbon polymer.

6. The method of claim 1 further including weaving the wall.

7. The method of claim 1 further including braiding the wall.

8. The method of claim 1 further including knitting the wall.
