HIGH PERFORMANCE WATERPROOF FABRIC
TECHNICAL FIELD OF THE INVENTION
The invention disclosed herein generally relates to a high performance, waterproof fabric. More particularly, the invention relates to an Ultra-High Molecular Weight Polyethylene (UHMWPE) based high performance fabric manufactured with core or sandwich type structure using 3D weaving technique.
BACKGROUND
Ultra-high-molecular-weight polyethylene (UHMWPE) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. Henceforth, UHMWPE characterized with high impact strength property of any other known thermoplastic material.
UHMWPE is odorless, tasteless, and non-toxic material. It embodies all the characteristics of high-density polyethylene (HDPE). UHMWPE is used in mooring and towing ropes, trawl ropes and nets, aquaculture nets, crane ropes, heavy lift slings, air cargo containers and nets, draglines and rope shovels for surface mining.
UHMWPE fibers or their blended fibers and like fibers are mostly used in dry state. To incorporate waterproof property in said fibers, the fibers are temporarily coated or laminated. However, this is not a permanent solution to the fibers and unreliable due to the occurrence of cracks between the plastic lamination layers of the fiber. The dried fibers may be exposed to oil, gas, water, sand, UV light, etc., which can damage, and minimize the life-cycle of the fibers. Further, UHMWPE like fibers are essentially one long molecule, or a linkage chain of molecules, which does not allow any chemicals, adhesives, or dyes to provide waterproofness, any fluid proof (gas, oil, etc.), UV proof and chemical resistant solution.
In light of the foregoing, there is need of a three-dimensional Ultra-High Molecular Weight Polyethylene (UHMWPE) based high performance fabric with good dimensional stability and strength, soft and light weight, waterproof, any fluid proof (gas, oil, etc.), UV proof and chemical resistant properties.
SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.
The present invention relates to a high-performance fabric, characterized by a core fiber comprising an Ultra-High Molecular Weight Polyethylene (UHMWPE) and a sheath or surface fiber comprising any one of natural, synthetic or combination thereof. Said sheath or surface fibers and core fibers are woven using 3D weaving technique to form Ultra-High Molecular Weight Polyethylene (UHMWPE) based core or sandwich type three-dimensional (3D) fabric. The Ultra-High Molecular Weight Polyethylene (UHMWPE) based core or sandwich type three-dimensional (3D) fabric is further treated with one or more resins to provide waterproof characteristics and enhances the mechanical property of the fabric. In one embodiment, the natural sheath fiber includes cotton, sisal, ramie, jute, bamboo and coir fibers. In another embodiment, the synthetic sheath fiber includes polyester, nylon, rayon, acrylic, aramids, modal, glass, and spandex fibers.
In one embodiment, the strength of the sheath fibers is comparatively lower to the core fibers. In some embodiments, the resin is, but not limited to, silicone or soft resins. In one embodiment, the resin is configured to adhere to the sheath fibers on either side of the core fiber such that the core fiber is unable to separate away from the resin and sheath fibers. Further, the core and sheath fibers are configured to distribute impact-load uniformly for ballistic fabric applications. In one embodiment, the core fibers are configured to absorb tension. In some embodiments, there are two weight (GSM) versions of high performance fabric in dry state with, 500 gm/m<2>at 8000 N, and 1100 gm/m<2>at 19000 N. Further, the weight (GSM) will be doubled as, 1000 gm/m<2>at 8000 N, and 2200 gm/m<2>at 19000 N during waterproof state of the high-performance fabric.
BRIEF DESCRIPTION OF THE DRAWINGS
The foregoing summary, as well as the following detailed description of the invention, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, exemplary constructions of the invention are shown in the drawings. However, the invention is not limited to the specific methods and structures disclosed herein. The description of a method step or a structure referenced by a numeral in a drawing is applicable to the description of that method step or structure shown by that same numeral in any subsequent drawing herein.
FIG. 1 exemplarily illustrates a cross-sectional view of a high-performance fabric according to an embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
Disclosed herein, an Ultra-High Molecular Weight Polyethylene (UHMWPE) based high performance fabric manufactured with core or sandwich type structure using 3D weaving technique.
Referring to FIG.1, a cross-sectional view of a high-performance fabric 100 is illustrated, according to an embodiment of the present invention. In an embodiment, the high-performance fabric 100 includes, a sheath or surface fiber 102 and a core fiber 104. In one embodiment, the core fibers 104 includes an Ultra-High Molecular Weight Polyethylene (UHMWPE) and sheath or surface fibers 102 comprises any one of natural, synthetic or combination thereof.
According to the present invention, said sheath or surface fibers 102 and core fibers 104 are woven using three-dimensional (3D) weaving technique to form Ultra-High Molecular Weight Polyethylene (UHMWPE) based core or sandwich type threedimensional (3D) fabric 100. The Ultra-High Molecular Weight Polyethylene (UHMWPE) based core or sandwich type three-dimensional (3D) fabric 100 is further treated with one or more resins to provide waterproof characteristics and enhances the mechanical property of the fabric.
In some embodiments, the resin is, but not limited to, silicone or soft resins. Silicone or any soft resin soaks and adheres to the surface fibers 102, and soaks through the strong core UHMWPE fibers 104. In one embodiment, the resin composition in the fabric 100, helps in incorporating different shore hardness, thickness, and contours of the soft-resin surface. In the present invention, the composition of the resin in the fabric 100 is tuned to provide “leather” like finish. In another embodiment, the resin composition in the fabric 100 is adjusted to provide more buoyancy, wear and tear resistance. In another embodiment, the resin composition in the fabric 100 is adjusted to provide different contours of the soft-resin surface, such that the fabric 100 is flat or with fine waterchannels for optimal fluid flow/less resistance. This makes the fabric 100 capable of being dyeable, printable, attachable, UV proof, chemical resistant, high friction resistant and rip-proof, with in technical specifications of each application.
In one embodiment, the natural sheath fiber 102 includes any one or combination of cotton, sisal, ramie, jute, bamboo and coir fibers. In another embodiment, the synthetic sheath fiber 102 includes any one or combination of polyester, nylon, rayon, acrylic, aramids, modal, glass, and spandex fibers. In one embodiment, the strength of the sheath fibers 102 is comparatively lower to the core fibers 104. In one embodiment, the resin is configured to adhere to the sheath fibers 102 on either side of the core fiber 104 such that the core fiber 104 is unable to separate away from the resin and sheath fibers 102.
Further, the core 104 and sheath fibers 102 is configured to distribute impact-load uniformly for ballistic fabric applications. In one embodiment, the core fibers 104 is a strong fiber, which is not woven, configured to absorb tension. In one embodiment, the strength of the fabric 100 could be adjusted by including more core fibers 104. In some embodiments, there are two strength/weight versions of high performance fabric 100 with, 500 gm/m<2>at 8000 N, and 1100 gm/m<2>at 19000 N. The fabric 100 could be packaged into rolls, up to 250 cm wide. Further, the fabric 100 could be printed or dyed, according to the requirement of the end-users.
Said high performance fabric 100 is processed to provide waterproof, any fluid proof (gas, oil, etc.), UV proof, chemical resistant solution and withstand considerable pressure in different circumstances (even under water), which opens a wide range of applications including, fluid tanks, transportation, armor, boats, etc. The fabric 100 further characterized with neutral buoyancy, where the fabric tends to float, which could be used as gas-container to avoid explosions. Further, if the gas-container made by this fabric 100 emptied, the gas-container is very light and can be shipped flat-packed, thereby provide saving on return freight, storage, etc. The fabric 100 could be incorporated in any application that require light weight, high strength, flexible, environmental proof properties. Further, the fabric 100 is customizable to required stiffness, colors, finishes, prints and contours (i.e. contours of surface of the soft resin).
The fabric 100 could be used for manufacturing knee-caps, helmets, protective garments, and further in a wide variety of industrial and personal use. The high-performance fabric 100, according to the present invention, comprises high modulus fibers and resins, configured to absorb huge amount of force and disperse the impact force uniformly along the surface of the fabric. This facilitates usage of fabric in ballistic protection, combat and defense applications. The fabric 100 could be packaged as a roll, a lightweight and waterproof material, which is 15 times stronger than the steel.
