Abstract
Description
Claims (25)
- 2. The method of forming a hose construction of claim 1 wherein said second hose element comprises a reinforcing braid.
- 3. The method of forming a hose construction of claim 1 wherein said first hose element comprises a tubular core element and said second hose element comprises a reinforcing braid wrapped thereabout under tension.
- 4. The method of forming a hose construction of claim 1 wherein said treating material comprises anHydrous hydrogen chloride gas.
- 5. The method of forming a hose construction of claim 1 wherein said treating material comprises an anhydrous hydrogen halide gas.
- 6. The method of forming a hose construction of claim 1 wherein said treating material comprises an anhydrous boron trifluoride gas.
- 7. The method of forming a hose construction of claim 1 wherein said treating material comprises a mixture of intermolecular hydrogen bond disrupting and inert materials.
- 8. The method of forming a hose construction of claim 1 wherein said second surface portion is urged against said first surface portion prior to the treating step.
- 9. The method of forming a hose construction of claim 1 wherein said second hose element is porous and said treating material is introduced to said first surface portion through said second porous hose element.
- 10. The method of forming a hose construction of claim 1 wherein said second hose element is formed of polyethylene terephthalate polyester resin.
- 11. The method of forming a hose construction of claim 1 wherein said steps are effected continuously.
- 12. The method of forming a hose construction of claim 1 wherein said treating step is carried out under anhydrous conditions.
- 13. The method of forming a hose construction of claim 1 wherein said treating material is removed by washing with water.
- 14. The method of forming a hose construction of claim 1 wherein said treating material is removed by heating.
- 15. A hose construction formed by the steps of: providing a first tubular hose element having a first synthetic linear polyamide surface portion; treating the surface portion to a material disrupting the intermolecular hydrogen bonds of -NH- and -CO- groups of said polyamide surface portion thereby to soften said surface portion; providing a fibrous second hose element having a second surface portion formed of a material substantially inert to said treating material; urging said fibrous second surface portion against said treated softened first surface portion of said tubular hose element to embed the fibrous second surface portion in said softened first surface portion of the tubular hose element; and removing the treating material to cause reformation of the spaced hydrogen bonds of said first surface portion to lock said fibrous second hose element surface portion to said first hose element surface portion.
- 16. The hose construction of claim 15 wherein said first hose element comprises a core and said second hose element comprises a braid wound onto said core.
- 17. The hose construction of claim 15 wherein said first hose element surface portion is formed of a material selected from the group of nylon 6, nylon 6/6 and nylon 6/10.
- 18. The hose construction of claim 15 wherein said second hose element is formed of polyethylene terephthalate polyester resin.
- 19. The hose construction of claim 15 wherein said second hose element comprises a reinforcement element.
- 20. The hose construction of claim 15 wherein said second hose element comprises a spiral wrapped reinforcement.
- 21. The hose construction of claim 15 wherein said treating material comprises anhydrous hydrogen chloride gas.
- 22. The hose construction of claim 15 wherein said treating material comprises an anhydrous hydrogen halide gas.
- 23. The hose construction of claim 15 wherein said treating material comprises an anhydrous boron trifluoride gas.
- 24. The hose construction of claim 15 wherein said treating material comprises a mixture of intermolecular hydrogen bond disrupting and inert materials.
- 25. The hose construction of claim 15 wherein said second surface portion is urged against said first surface portion prior to the treating step.
- 26. The hose construction of claim 15 wherein said second hose element is porous and said treating material is introduced to said first surface portion through said second porous hose element.
