FABRIC TO CONFER RESISTANCE TO THE UNWINDING OF EXTREMES AND PROTECTIVE COVERS CONFORMED THEREOF AND METHODS OF MANUFACTURING CROSS REFERENCE FOR RELATED APPLICATION This use claims the benefit of US Provisional Patent Application No. 60 / 760,057, filed January 19, 2006, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION 1. Technical Field This invention relates in general to textile fabrics and their manufacturing methods, and more particularly, to textile fabrics of the type incorporating woven filamentary plastic materials that are structured to form protective sheaths for elongated members. 2. Related technique Conductor bundles, hoses, pipes and similar in general must withstand severe environmental conditions in automotive, industrial, aerospace, marine and other applications. For example, conductor bundles can be subjected to excessive heating or vibration during vehicle operation that can damage the conductor bundle and impair its operation and reduce its useful service life.

It is common to cover the bundles of conductors with a protective cover to protect them from these harsh environments. One of these covers includes a woven substrate that incorporates a plurality of multifilaments and / or monofilaments that are made of a plastic material designed that can be thermofixed to form a generally tubular, packable product. The filaments near the edges of the sheath (ie, near the ends or along the longitudinal slit) tend to stick out, fray and / or fall off when the product is cut lengthwise. Apart from being aesthetically unpleasant, the frayed, protruding filaments can contaminate the tubes, hoses or bundles of conductors on which the sleeve is disposed, interfering with the ability to properly connect end fittings or couplings with their corresponding parts. The protective covers can also be braided or knitted to finally take an elongated tubular shape and can include multifilaments and / or monofilaments which, when the cover is cut lengthwise, can fray at the ends.

BRIEF DESCRIPTION OF THE INVENTION An elongated protective textile cover for the protection of a conduit, hose, bundle of conductors or the like comprises a woven substrate of a plurality of filamentary members and other material. The substrate can be woven, knitted or braided. At least some filamentary members of the substrate extend at the cutting edges and are made of a multicomponent material that includes a core of a first polymeric material and an outer sheath of a second polymeric material. The outer sheath is thermofusible and the inner core is thermoplastic. The outer sheaths of the filamentary members are thermofused to the other material at least in the regions near the cutting edges to keep the cutting edges unraveled or the filamentary members and other material from leaving the substrate, while the core is thermofixed to Shape the desired shape of the protective cover. According to a currently preferred embodiment, the substrate includes a plurality of first filamentary members oriented in a first direction and a plurality of second filamentary members oriented in a second direction transverse to the first direction. The first filamentary members are configured in space separately in relation to the others and the second filamentary members are configured separately in relation to the others. The first filamentary members are intertwined with the second filamentary members to define an open mesh. A plurality of elongated strips of the nonwoven material extends in the first direction in the spaces between the first filamentary members and is entangled with the second filamentous members. The second filamentary members are made of a multiple material including a core of thermosetting plastic material which is formed by heat to impart a tubular sheath shape to the substrate and an outer sheath of the thermofusible plastic material which is bonded to the strips of nonwoven material of the substrate. The joining of the second filamentary members to the non-woven strips provides support to the second filamentary members of fraying at the edges of the substrate or of leaving the substrate, particularly when the substrate is cut lengthwise. According to another currently preferred textile sleeve method, a substrate of filamentary members is interlaced with each other, in at least some of the filamentary members which are monofilaments having a core of the thermosetting polymeric material and an outer sheath of thermofusible polymeric material. The outer sheaths of the monofilaments are heat-fused together along at least a portion of the sheath and preferably adjacent their opposite ends to prevent the sheath from fraying from its ends, particularly when the sheath is cut lengthwise. According to another aspect of the invention, a method for forming a textile fabric is provided. The method includes providing the bi-material of filamentary members having a core of thermosetting polymeric material and an outer sheath of thermofusible polymeric material different from the thermosetting polymeric material and at least one material separate from the filamentary members.

DETAILED DESCRIPTION OF CURRENTLY PREFERRED MODALITIES Referring in greater detail to the figures, Figures 1 and 2 illustrate protective textile covers 10, 11 according to presently preferred embodiments, wherein the covers 10, 11 are similar, however the cover 10 is generally cylindrical in shape. the cross section cut, while the sheath 11 is generally oval or flat in cross section cut. Given the similarities, the covers are generally the same, and thus, the same reference numbers are used to identify their structures. The sheaths 10, 11 include a fabric, also referred to as a substrate 12, wherein the substrate has interlaced cables that can be woven or knitted. By way of example and without limitation, the illustrated covers 10, 11 are woven. As best shown in Figure 3, the substrate 12 includes a plurality of first filamentary members 14 that are oriented in a first direction indicated by the arrow 16. For a woven substrate, the arrow 16 corresponds to the warp direction, which corresponds to a longitudinal axis 17 extending along a length of the sheath 10. The substrate 12 includes a plurality of second filamentary members 18 which are oriented in a second direction indicated by the arrow 20. On a woven substrate, the direction indicated by the arrow 20 corresponds to the weft or weft direction, which corresponds to a width of direction of the sheath 10. The first filamentary members 14 can be interlaced, such as by woven, with the second filamentary members 18. In an embodiment currently preferred, at least some of the first filamentary members 14 are separated apart from the adjacent ones of the other of the first filamentous fibers 14 in such a way that there is a plurality of spaces 22 generally open between the adjacent ones of the first filamentary members 14 separated. As illustrated, the first filamentary members 14 can be arranged in strongly woven groupings 24 of the members 14 such that the multiple layers of the members 14 are configured in succession with each other, but separated from surrounding groups by the intermediate open spaces 22. The second filamentary members 18 are separated from each other in such a way that an open mesh of the first and second members 14, 18 is defined. According to the present embodiments, the open spaces 22 are present with elongated strips of a third material non-woven 26. The strips 26 may comprise nonwoven polyester, polypropylene, nylon, glass fiber, elastomeric materials, polymeric materials, foams and the like.

For example, the strips 26 are shown here interwoven or woven between the second filamentary members 18 and extend in the same direction as the first filamentary members 14. The strips 26 may extend the total width of the space 22 between the first adjacent filamentary members. 14. The first filamentary members 14 may comprise monofilaments and / or multifilament cables formed of materials such as polyester and the like.

The second filamentary members 18 oriented in the direction of the weft are monofilaments preferably of multiple materials. As schematically illustrated in Figure 4, at least some of the second filamentary members 18 have a core / sheath structure including a core 28 made of a coated plastic material designed by a sheath 30 of different plastic materials which, when heated, it causes the sheath 30 to melt or join the strips of nonwoven material 26. The sheath 30 can be made of a material having a melting temperature lower than that of the inner core 18, such as polypropylene, polyethylene, polyester, or the like. The fusion and joining of the sheath 30 to the non-woven strips 26 serves to intimately join the strips 26 to the second filamentary members 18. This acts to secure in place the strips 26 and further ensures the second filamentary members to fray at the ends of cutting 32 of the substrate 12 or of being removed from the substrate 12. The fusion of the second filamentary members 18 across the total width of the non-woven strips 26 acts to prevent lateral movement or stacking of the strips 26 in relation to the first ones. filamentary members 14 to maintain a tight tissue structure without taking into account the width used for the non-woven filling strips 26. Accordingly, the strips 26 can vary in width, be relatively narrow to relatively broad, in accordance with the intended use of the cover. The inner core 28 of the secondary filamentary members 18 can be manufactured from a heat-formed plastic material design, also referred to as thermosetting, such as nylon, PPS, or the like. The core 28 allows the substrate 12 to be formed by heat in the self-enclosing sheath with opposite edges 33, 35 of the sheath 10, 11 arranged in superposed relation to each other. When the cores 28 are thermoset, the cores 28 provide an elastically resistant support for the substrate 12 which allows the edges 33, 35 of the sheath 10 to be forced open to introduce elongated members, such as a conductor bundle 37 or other object elongated, for example, in a cavity of the cover for protection. After disposing the elongated members 37 in the cavity, the edges 33, 35 of the sheath 10, 11 return to a closed condition under the closing tendency by the force imparted by the cores 28 of the second filamentary members 18. With the sheath 30 attached to the non-woven strips 26, there is no slippage of the second filamentary members 18 relative to the strips 26 and thus the union improves the tightening and elasticity of the curl conferred by the core 28. Another currently preferred embodiment of a manufacturing of sheath 34 is illustrated in Figure 5. This sheath 34 is a woven or woven knit and has a tubular wall 39 closed and circumferentially continuous along its length, unlike the self-enclosing sheaths of Figures 1- 2. The sheath 34 also minimizes or fraying the filamentary members along the opposite cut ends 38, 40 of the sheath 34. In this embodiment, the circular knit fabric or braided sheath is made of a plurality of individual filamentary members, at least some of which comprise monofilament designed plastic material which is prone to finish fraying and / or unraveling when cut. Similar to the first modality, the sheath 34 incorporates at least some multi-component monofilaments 36 having the same core / sheath structure as described above and illustrated in Figure 4. In this embodiment, at least some of the monofilaments 36 are attached to themselves and / or the adjacent filamentary members of a different material at selected positions 41, particularly near the opposite cutting ends 38, 40 of the sheath 34 to prevent the monofilaments 36 from fraying, unraveling and / or leaving the sheath 34. As such, the sheath 34 can be trimmed without the concern of damaging the protective aspects and / or sheath life. Another currently preferred embodiment of a sheath fabrication 50 is illustrated in Figure 6. The sheath 50 has a substrate fabricated in the manner of a layer of central support fabric 52, preferably having opposite inner and outer layers of the material 54, 56 attached to it. the same. As best shown in Figure 8, the substrate 52 preferably includes a plurality of first filamentary members 14 that are oriented in a first direction corresponding to the length of the sheath 50 and a plurality of second filamentary members 18 that are oriented in a second direction corresponding to a width of direction of the sheath 10. The first filamentary members 14 may be woven or otherwise interlocked with the second filamentary members 18, as described above with respect to the first embodiment described. The first filamentary members 14 are separated from one another to provide a plurality of generally open spaces 22 between adjacent ones of the first separate filamentary members 14. As shown, at least some first filamentary members 14 can be formed into strongly woven assemblies 24, where the groupings 24 are separated from surrounding groups by the intermediate open spaces 22. The second filamentary members 18 are interlocked with the first filamentary members. 14 to provide open mesh fabrication for the substrate. The second filamentary members 18 are fabricated having a thermosetting inner core 28 and an outer thermofusible sheath 30, as described above and shown in Figure 4. The substrate 52 has opposite sides 58, 59, where at least one layer of the material is attached to one of the sides 58, 59. In this embodiment, as shown in Figures 6 and 7, a side 58 of the substrate 52 is oriented to an outer surface 60 of the sheath 50 and has the outer layer of the material 56. attached thereto to provide the outer surface 60. The material 56 has a refractive surface 62 and thus, is provided as a metallic material, for example a metal shell or a metallized material, such as for example, mylar (polyterephthalate film of ethylene) metallized. The other side 59 is oriented towards the inner surface 64 of the sheath 50 and has the inner layer of the material 54 attached thereto. The inner layer of the material 54 is provided as a non-woven insulating material, for example, polyester, polypropylene, nylon, glass fiber, elastomeric materials, polymeric materials, foams and the like. It should be recognized that any of these internal and external layers of the material 54, 56 could be attached to both sides 58, 59 instead of being in combination with each other, depending on the application. Accordingly, the substrate 52 can have nonwoven materials 54 bonded to both sides 58, 59, or refractive materials 56 attached to both sides 58, 59. To join the inner and outer layers 54, 56 to the central substrate 52, the layers 54 , 56 are preferably thermofused to the opposite sides 58, 59 of the support fabric 52 by means of the outer sheath 30 of the second filaments 18. This process can be carried out in line with the textile machine that is used to manufacture the Substrate 52, such that the interlaced substrate 52 can exit the textile machine and directly attach to at least one of the layers 54, 56, such as when it is hot-melted between a pair of hot rolls (not shown). In addition to, or in place of the hot melt, an adhesive layer 66, such as a pressure sensitive glue, for example, could also be used to bond either the inner and / or outer layers 54, 56 to the substrate 52. Adhesive layer 66 may have glue on both sides, for example and could also be applied to substrate 52 in line with the textile machine, as described above, or in a separate process, as desired. In this way, one of the layers can first be thermofused to the substrate 52, while the other layer can be joined from the adhesive layer 66. This provides flexibility in the manufacturing process by providing the layers 54, 56 for be attached to the substrate 52 in either an individual operation or, if desired, in separate operations. At the time of joining the inner and outer layers 54, 56 to the support fabric 52, the multilayer fabric can be manufactured in the form of a desired protective cover, which is generally cylindrical, as shown in Figure 6, or generally flat, as shown in the previous modality in Figure 2, depending on the application. In order to manufacture the multilayer fabric in its finished form, the fabric can be cut, if necessary and shaped into the desired shape, such as through a rolling process between opposite rollers otherwise formed and / or pressed, in where heat is applied to the cores 28 of the secondary filaments 18, thereby providing thermosetting in the cores 18, and thus, the multi-layered fabric. Accordingly, the multilayer fabric is manufactured to retain the thermoformed partial form, with opposite edges of the multilayer fabric extending along the sheath preferably formed in superposed relation to each other. As in the embodiments discussed above, with the outer sheaths 30 of the secondary filaments 18 that have been thermofused to the inner and outer layers of laminate 54, 56, the resulting fabric and sheath can be cut lengthwise without incurring the extreme fraying or having filaments that on the other hand can be separated from the multilayer fabric. Another currently preferred embodiment of a sheath manufacture 70 is illustrated in Figure 9. The sheath 70 is similar to the sheath 50 shown in Figure 6, and has a layer 72 of central support fabric manufactured in the same manner as described above, in such a way that the support fabric or substrate are thermosettable through the bicomponent filaments. The substrate 72 has opposite sides 74, 75, but unlike the previous embodiment, only one layer is shown here as an outer metal sheet layer 76 which is attached to one of the sides 74. Accordingly, the other side 75 of the support fabric 72 remains exposed, resulting in a finished cover having reduced weight and thickness. As discussed above, the metal foil layer 76 may be bonded to the substrate 72 by means of a heat fusion process, wherein the metal foil layer 76 is bonded to an outer heat-fusible sheath 30 of the monofilaments 18 used in the manufacture of the substrate 72. At the time of joining the sheet metal layer 76 to the substrate 72, the substrate can be tubular thermofixed in general so that the sheath 70 is screwed on by itself. To ensure that the sheath 70 remains wrapped over the elongated members, an additional locking mechanism 78 can be incorporated to prevent the sheath 70 from accidentally unrolling, thus providing additional protection to the elongated members. The locking mechanism 78 is preferably provided to provide a circumferentially continuous sheet metal layer on the sheath 70., thereby increasing the protective EMI capabilities of the sheath 70. Accordingly, the closure mechanism 78 is provided as a metal foil layer having a self-adhesive surface 80. A portion 84 of the self-adhesive surface is partially covered by a release paper. 82 to prevent the adherent surface 80 from extending beyond the edge 85 of the sheath 70 which can become contaminated or stick to other surfaces before the sheath 70 is installed on the elongated members to be protected. Another portion 86 of self-adhesive surface 80 has the release paper 82 removed therefrom in such a way that the exposed glue can be bonded to an external surface 87 of the metal sheet layer 76. With the metal sheet layer closing mechanism. 78 extending beyond the edge 85 of the metal foil layer 76, when wrapping the sheath 70 over the elongated members and removing the release paper 82, the adherent surface 80 of the closing metal foil 78 can be adhered to the external surface 87 of the overlapping sheath edge to secure the edges of the sheath in an overlapping arrangement with each other. As such, the sheath 70 has a circumferentially continuous outer metallic sheet surface to increase the sheath's ability to provide protection against EMI. To further increase the EMI shield field capability of the sheath 70, at least one drain wire 88 may be attached for electrical conductive communication with the outer metal sheet layer 76. As shown, the drain wire 88 it may be attached to any portion of the sheath 70, such as by a rivet connection 90, for example. On the other hand, one end of the drain wire 88 may be joined between the substrate 72 and the outer metal sheet layer 76, as shown by way of example in Figure 9, during the hot melt or bonding process of the outer layer. outer metallic sheet 76 to substrate 72. It becomes obvious that many modifications and variations of the present invention are possible in light of the above teachings. This is, therefore, that within the understanding of the scope of the appended claims, the invention can be put into practice as specifically described.
