Abstract

A protective textile sleeve having a flexible, tubular wall of braided yarns and method of construction thereof is provided. At least some of the yarns include plastically deformable and/or heat-settable monofilaments and/or multifilaments that are plastically deformed and/or heat-set to provide the wall with a convolute shape. The convolute shape is formed by a plurality of alternating crests and valleys, wherein the crests are formed in tight, axially compressed relation with one another, with the valleys intervening between the crests being relatively narrow or short in axially extending length relative to the crests, providing the wall with an increased density, an increased abrasion resistance, enhanced thermal protection, enhanced impact resistance, enhanced noise attenuation. Further, with the wall having an accordion-like shape, greatly enhanced flexibility is attained without concern of kinking when routing the sleeve about meandering paths and about sharp bends, corners and the like.

First claim

What is claimed is:

1 . A convolute protective textile sleeve, comprising:
a flexible, tubular wall of braided yarns, at least some of the yarns being provided as plastically deformable and/or heat-settable monofilaments that are plastically deformed and/or heat-set upon being braided to provide the wall with an accordion-like, convolute shape, the convolute shape being formed by a plurality of alternating crests and valleys, wherein the crests are formed in tight, axially compressed relation with one another, with the valleys intervening between the crests being relatively narrow or short in axially extending length relative to the crests.

2 . The convolute protective sleeve of claim 1 , wherein the wall is formed entirely of plastically deformed and/or heat-set monofilaments.

3 . The convolute protective sleeve of claim 2 , wherein the wall is formed entirely of plastically deformed monofilaments.

4 . The convolute protective sleeve of claim 2 , wherein the wall is formed entirely of heat-set monofilaments.

5 . The convolute protective sleeve of claim 1 , wherein the wall includes multifilaments.

6 . The convolute protective sleeve of claim 5 , wherein at least some of the multifilaments are plastically deformed and/or heat-set.

7 . The convolute protective sleeve of claim 6 , wherein at least some of the multifilaments are neither plastically deformed nor heat-set.

8 . The convolute protective sleeve of claim 7 , wherein the wall includes heat-set monofilaments.

9 . The convolute protective sleeve of claim 8 , wherein the wall is entirely formed of heat-set monofilaments and multifilaments that are neither plastically deformable nor heat-settable.

10 . The convolute protective sleeve of claim 8 , wherein the wall is entirely formed of heat-set multifilaments and multifilaments that are neither plastically deformable nor heat-settable.

11 . A method of constructing a convolute textile sleeve, comprising:
braiding a circumferentially continuous wall including plastically deformable and/or heat-settable yarns; compressing the wall axially along a longitudinal axis of the wall and forming the wall having an accordion-like shape with alternating crests and valleys; and plastically deforming and/or heat-setting the wall while in the axially compressed state such that the heat-set yarns maintain the wall in the accordion-like configuration.

12 . The method of claim 11 , further including braiding the wall entirely of plastically deformable and/or heat-settable monofilaments.

13 . The method of claim 12 , further including braiding the wall entirely of plastically deformed monofilaments.

14 . The method of claim 12 , further including braiding the wall entirely of heat-settable monofilaments.

15 . The method of claim 11 , further including braiding the wall including multifilaments.

16 . The method of claim 15 , further including plastically deforming and/or heat-setting at least some of the multifilaments.

17 . The method of claim 16 , further including providing at least some of the multifilaments as being neither plastically deformable nor heat-settable.

18 . The method of claim 17 , further including braiding the wall entirely of heat-settable monofilaments and multifilaments that are neither plastically deformable nor heat-settable.

19 . The method of claim 18 , further including braiding the wall entirely of heat-settable multifilaments and multifilaments that are neither plastically deformable nor heat-settable.

20 . The method of claim 11 , further including heat-setting or plastically deforming the wall so that the crests are tightly packed immediately adjacent one another with the intervening valleys having a relatively short axially extending length relative to the length of the individual crests, thereby providing the wall with a significantly increased linear density relative to the wall as initially braided and prior to being heat-set or plastically deformed.
