Abstract

A single layer/ply mutli-use hose is contemplated. A thermoplastic polymer, such as polyurethane, is extruded through a woven tubular mesh of aramid fibers so as to encourage pillaring through gaps in the mesh of a sufficient amount to improve the overall durability and strength of the resultant hose. This wide diameter (at least 4 inches) and long continuous length (at least 300 feet) hose exhibits excellent durability (e.g., resistance to abrasion and/or punctures) and tensile ratios in excess of 2:1 so as to withstand tensile loads in excess of 100,000 pounds without delamination or bubbling within the hose wall.

Claims

exact text as granted — not AI-modified
1 - 20 . (canceled) 
     
     
         21 . A single layer, flexible hose consisting of: a woven tubular mesh formed from warp yarn having a different effective diameter in comparison to fill yarn so as to provide an open weave, wherein said warp and fill yarns each consist essentially of para-aramid and/or meta-aramid fibers, wherein a thermoplastic polymer completely encases the woven tubular mesh so as to form pillars of thermoplastic polymer filling the open weave, and wherein the encased woven tubular mesh imparts a tensile ratio of at least 2 to 1 to the single layer, flexible hose. 
     
     
         22 . The single layer, flexible hose of  claim 21  wherein the thermoplastic polymer consists essentially of thermoplastic polyurethane and/or thermoplastic vulcanizate. 
     
     
         23 . The single layer, flexible hose of  claim 21  wherein the thermoplastic polymer is at least one selected from the group consisting of: ethylene propylene diene monomer rubber (EPDM), mixtures of EPDM and styrene butadiene rubber (SBR), polychloroprene, and nitrile rubber. 
     
     
         24 . The single layer, flexible hose of  claim 21  wherein the warp yarn is woven into alternating risers and sinkers and wherein at least either or both of the risers and sinkers of the warp yarn each traverse two strands of filler yarn. 
     
     
         25 . The single layer, flexible hose of  claim 21  wherein the thermoplastic polymer consists essentially of polyester-based and/or polyether-based thermoplastic polyurethane(s). 
     
     
         26 . The single layer, flexible hose of  claim 21  wherein the single layer, flexible hose has a bend radius of at least 90° without inducing kinking and permanent deformation of the single layer, flexible hose. 
     
     
         27 . The single layer, flexible hose of  claim 21  wherein the single layer, flexible hose will collapse when fluid pressure is not provide along an inner lumen defined by the single layer, flexible hose. 
     
     
         28 . The single layer, flexible hose of  claim 21  wherein the woven tubular mesh has a length of between 300 and 1,320 feet. 
     
     
         29 . The single layer, flexible hose of  claim 21  wherein the woven tubular mesh has a nominal diameter of between 4 and 16 inches. 
     
     
         30 . The single layer, flexible hose of  claim 21  wherein the single layer hose has a burst pressure rating between at least 600 and 750 pounds per square inch. 
     
     
         31 . The single layer, flexible hose of  claim 21  wherein the single layer hose has a tensile strength 100,000 pounds and 200,000 pounds. 
     
     
         32 . The single layer, flexible hose of  claim 21  wherein a radial height of the pillars is between 0.0467 and 0.0636 inches. 
     
     
         33 . The single layer, flexible hose of  claim 21  wherein the open weave includes warp gap widths between 0.04540 and 0.05745 inches and filler gap widths between 0.0362 and 0.0483 inches. 
     
     
         34 . The single layer, flexible hose of  claim 21  wherein the fill yarn and/or the warp yarn has between 5 to 9 ply. 
     
     
         35 . The single layer, flexible hose of  claim 21  wherein the fill yarn and/or the warp yarn has denier of 1500, 2600, and/or 3000. 
     
     
         36 . The single layer, flexible hose of  claim 21  wherein the fill yarn and/or the warp yarn has a thickness of 0.033, 0.035, 0.040, 0.045, 0.048, and/or 0.050 inches.
