Abstract

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.

First claim

What is claimed is:

1. An end fray resistant textile sleeve for protecting elongate members, comprising:
an elongate wall having warp yarns woven with weft yarns, said warp yarns extending lengthwise in generally parallel relation to a longitudinal central axis between opposite ends and said weft yarns extending generally transversely to said warp yarns, said warp yarns including at least two different types of warp yarns, with one type of said warp yarns including a plurality of activateable warp yarns coated with an activateable adhesive material and another type of said warp yarns including a plurality of non-activateable warp yarns, said activateable warp yarns being activateable by at least one of heat, fluid and/or pressure, wherein upon said activateable warp yarns being activated to form activated warp yarns, said activated warp yarns become bonded with adjacent ones of said non-activateable warp yarns and with said weft yarns, at least some of said activated warp yarns being spaced circumferentially from one another by at least some of said non-activateable warp yarns, wherein said activated warp yarns include multifilaments of non-activateable material coated with the activated coating of adhesive material.

2. The end fray resistant textile sleeve of claim 1 wherein said warp yarns and said weft yarns are woven in one of a plain, rib, basket or twill weave pattern.

3. The end fray resistant textile sleeve of claim 1 wherein said weft yarns include multifilaments.

4. The end fray resistant textile sleeve of claim 1 wherein said activateable warp yarns are activated to form activated warp yarns, wherein said activated warp yarns are arranged in a plurality of bundles, each of said bundles including a plurality of activated warp yarns arranged in side-by-side abutting relation with one another, each of said bundles being spaced circumferentially from one another by a plurality of said non-activateable warp yarns.

5. The end fray resistant textile sleeve of claim 4 wherein abutting ones of said activated warp yarns of said bundles undulate over and under said weft yarns out of phase with one another.

6. The end fray resistant textile sleeve of claim 1 wherein said elongate wall is a wrappable wall having opposite edges extending generally parallel to said longitudinal central axis.

7. The end fray resistant textile sleeve of claim 6 wherein said weft yarns include heat-set yarns, said heat-set yarns biasing said opposite edges into overlapping relation with one another.

8. The end fray resistant textile sleeve of claim 6 wherein at least some of said activated warp yarns extend along said opposite edges.

9. The end fray resistant textile sleeve of claim 8 wherein said activated warp yarns extending along said opposite edges are spaced from one another entirely by said non-activateable warp yarns.
