Wrappable end fray resistant protective textile sleeve and method of construction thereof
View Patent ↗A wrappable textile sleeve and method of construction 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 and the fill yarns are woven in an overlying and underlying weave pattern with one another. The warp yarns are arranged in discrete groups alternating about a circumference of the wall with adjacent groups having a different number of the warp yarns. As such, the wall is provided with groups of increased numbers of warp yarns that provide the sleeve with enhanced rigidity and abrasion resistance, while also being provided with groups of decreased numbers of warp yarns that provide the sleeve with enhanced flexibility along the longitudinal central axis.
1. A wrappable end fray resistant textile sleeve for protecting elongate members, comprising:
an elongate wall having warp yarns extending generally parallel to a longitudinal central axis of said sleeve and fill yarns extending circumferentially about said sleeve, said warp yarns and said fill yarns being woven in an overlying and underlying weave pattern with one another; and
said warp yarns being arranged in discrete groups alternating about a circumference of said wall, each of said discrete groups being woven in a single dent, with adjacent groups occupying substantially the same circumferential width and having a different number of said warp yarns.
2. The wrappable end fray resistant textile sleeve of claim 1 wherein said overlying and underlying weave pattern is a plain weave pattern.
3. The wrappable end fray resistant textile sleeve of claim 2 wherein each of said warp yarns in each of said discrete groups is woven in said plain weave pattern with said fill yarns.
4. The wrappable end fray resistant textile sleeve of claim 1 wherein said different numbers of said warp yarns in said adjacent groups are X and Y, wherein X is greater than Y.
5. The wrappable end fray resistant textile sleeve of claim 3 wherein X equals 4 and Y equals 1.
6. The wrappable end fray resistant textile sleeve of claim 1 wherein said warp yarns are monofilaments heat-set in a sinusoidal configuration.
7. The wrappable end fray resistant textile sleeve of claim 6 wherein said fill yarns are multifilaments.
8. The wrappable end fray resistant textile sleeve of claim 7 wherein said multifilaments have an air texturized finish.
9. The wrappable end fray resistant textile sleeve of claim 6 wherein said wall has opposite edges extending along said central longitudinal axis, said opposite edges being configured in overlapping relation with one another.
10. A method of constructing a wrappable end fray resistant textile sleeve for protecting elongate members, comprising:
forming an elongate wall by weaving warp yarns and fill yarns with one another in an overlying and underlying weave pattern; and
weaving said warp yarns in discrete groups alternating about a circumference of the wall with each of said discrete groups being woven in a single dent, with adjacent groups occupying substantially the same circumferential width and having a different number of said warp yarns.
11. The method of claim 10 further including forming the overlying and underlying weave pattern as a plain weave pattern.
12. The method of claim 11 further including weaving each of the warp yarns in each of the discrete groups with the fill yarns in the plain weave pattern.
13. The method of claim 10 further including arranging the different number of warp yarns in the adjacent groups having X and Y numbers of respective warp yarns, wherein X is greater than Y.
14. The method of claim 13 further including configuring X to equal 4 and configuring Y to equal 1.
15. The method of claim 10 further including providing the warp yarns as monofilaments and heat-setting the warp yarns to take on a sinusoidal shape.
16. The method of claim 15 further including heat-setting the warp yarns in a calendaring process.
17. The method of claim 15 further including providing the fill yarns as multifilaments.
18. The method of claim 17 further including providing the fill yarns having an air texturized finish.
19. The method of claim 10 further including weaving the wall as a flat fabric.
20. The wrappable end fray resistant textile sleeve of claim 1 wherein said adjacent groups having a different density of said warp yarns.
