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 a plurality of activateable warp yarns and a plurality of non-activateable warp yarns, said activateable warp yarns being activateable by at least one of heat, fluid and/or pressure, wherein said activateable warp yarns are activated and bonded with adjacent ones of said non-activateable warp yarns and with said weft yarns, at least some of said activated warp yarns being arranged in side-by-side, abutting relation with one another to form a plurality of bundled activated warp yarns, each of said bundled activated warp yarns being spaced circumferentially from one another by at least some of said non-activateable warp yarns.

2. The end fray resistant textile sleeve of claim 1 wherein the activated yarns are monofilaments.

3. The end fray resistant textile sleeve of claim 1 wherein the activated yarns are multifilaments.

4. The end fray resistant textile sleeve of claim 1 wherein said activateable yarns are bicomponent monofilaments having a central core of a material with a first melt temperature and an outer sheath of a material with a second melt temperature, wherein the first melt temperature is higher than the second melt temperature.

5. The end fray resistant textile sleeve of claim 1 wherein said activateable yarns are entangled yarns including non-activateable material entangled with activateable material.

6. The end fray resistant textile sleeve of claim 1 wherein said activateable yarns include a non-activateable monofilament or multifilament yarn twisted or served with an activateable monofilament or multifilament yarn.

7. The end fray resistant textile sleeve of claim 1 wherein said elongate wall is a seamless, circumferentially continuous wall.
