Abstract

A protective textile sleeve and method of construction thereof is provided. The sleeve has a flexible, tubular wall of braided yarns. At least some of the yarns are provided as a plurality of monofilaments and at least some of the yarns are provided as a plurality of multifilaments. The plurality of multifilaments are braided in a plurality of separate bundles. Each of the bundles includes at least two multifilaments. The monofilaments are embedded into the multifilaments during the braiding process to lock the multifilaments in an “as braided” location to prevent shifting of the multifilaments during application and during use, thereby enhancing the abrasion resistance of the sleeve wall.

First claim

What is claimed is:

1. A protective textile sleeve, comprising:
a flexible, tubular wall of braided yarns, at least some of said yarns being provided as monofilaments and at least some of said yarns being provided as multifilaments, said multifilaments being braided in a plurality of separate bundles, each of said bundles including at least two multifilaments, wherein said flexible, tubular wall has an outer surface density of between 500-700 g/m 2 .

2. The protective textile sleeve of claim 1 , wherein each of said multifilaments has a denier of between 1000-1200 dTex.

3. The protective textile sleeve of claim 2 , wherein each of said multifilaments has a tenacity between 60-85 cN/tex.

4. The protective textile sleeve of claim 3 , wherein said multifilaments are polyester.

5. The protective textile sleeve of claim 2 , wherein said monofilaments have a diameter between 0.35-0.40 mm.

6. The protective textile sleeve of claim 1 , wherein said monofilaments have a tenacity between 40-55 cN/tex.

7. The protective textile sleeve of claim 1 , wherein said monofilaments have a Young's Modulus of 3 GPa.

8. The protective textile sleeve of claim 1 , wherein said multifilaments and said monofilaments are provided in a respective ratio of 2:1.

9. A protective textile sleeve, comprising:
a flexible, tubular wall of braided yarns, at least some of said yarns being provided as monofilaments and at least some of said yarns being provided as multifilaments, said multifilaments being braided in a plurality of separate bundles, each of said bundles including at least two multifilaments, wherein said monofilaments have a tenacity between 40-55 cN/tex.

10. The protective textile sleeve of claim 9 , wherein each of said multifilaments has a denier of between 1000-1200 dTex.

11. The protective textile sleeve of claim 9 , wherein each of said multifilaments has a tenacity between 60-85 cN/tex.

12. The protective textile sleeve of claim 9 , wherein said monofilaments have a diameter between 0.35-0.40 mm.

13. The protective textile sleeve of claim 9 , wherein said monofilaments have a Young's Modulus of 3 GPa.

14. A protective textile sleeve, comprising:
a flexible, tubular wall of braided yarns, at least some of said yarns being provided as monofilaments and at least some of said yarns being provided as multifilaments, said multifilaments being braided in a plurality of separate bundles, each of said bundles including at least two multifilaments, wherein said monofilaments have a Young's Modulus of 3 GPa.

15. The protective textile sleeve of claim 14 , wherein each of said multifilaments has a denier of between 1000-1200 dTex.

16. The protective textile sleeve of claim 14 , wherein each of said multifilaments has a tenacity between 60-85 cN/tex.

17. The protective textile sleeve of claim 14 , wherein said monofilaments have a diameter between 0.35-0.40 mm.

18. A method of constructing a protective textile sleeve, comprising:
braiding a flexible, tubular wall from monofilaments having a tenacity between 40-55 cN/tex and multifilaments each having a denier of between 1000-1200 dTex, with the multifilaments being braided as a plurality of separate bundles, with each of the separate bundles including at least two multifilaments, and embedding the monofilaments into the multifilaments during the braiding process to effectively lock the multifilaments in place.

19. The method of claim 18 , further including providing the multifilaments each having a tenacity between 60-85 cN/tex.

20. The method of claim 18 , further including providing the monofilaments having a diameter between 0.35-0.40 mm.

21. The method of claim 18 , further including providing the monofilaments having a Young's Modulus of 3 GPa.
