专利说明:
[0001] The present invention relates to a fabric which can be attached by welding to a substrate. [0001] BACKGROUND OF THE INVENTION
[0002] Heretofore in welding fabric to a substrate, the fabric used was a belt-form fabric with a special design. As shown in FIG. 9A, at least a portion of the belt-form fabric is woven with a coarse weave. FIG. 9B illustrates how this fabric T is welded to a substrate in the form of a sheet, S. The coarsely woven portion t is sandwiched between a welding tape M and substrate S and heat-pressed so that the welding tape is melted and flows into the gaps of the coarsely woven portion t. Thus, the fabric T is united with substrate S. [0002]
[0003] Unfortunately, the conventional fabrics used for welding require that the welding tape M be correctly positioned on the coarsely woven portion of the belt-form fabric T overlapped on the welding zone of the substrate S. This correct positioning is troublesome, and requires considerable expenditure of time and labor. [0003] SUMMARY OF THE INVENTION
[0004] It is an object of the present invention to overcome the aforementioned deficiencies of the prior art. [0004]
[0005] It is another object of the present invention to provide a fabric for welding which can easily be welded to any type of substrate that can be subjected to hot pressing. [0005]
[0006] According to the present invention, a fabric for welding is provided which has a welding portion integral with the fabric which extends partially or completely over the width of the fabric. The welding portion of the fabric comprises at least a warp or weft which melts under hot pressing to adhere the fabric to a substrate. The substrate may be a cloth sheet, a synthetic resin sheet, or the like. This enables one to attach the sheet to a column, a stake, a log, a building, a footing, etc., or to attach the welding fabric to another sheet. [0006] BRIEF DESCRIPTION OF THE DRAWINGS

[0023] FIG. 9B illustrates how the fabric of FIG. 9A is welded to a substrate. [0023] DETAILED DESCRIPTION OF THE INVENTION
[0024] The fabric for welding according to the present invention can be any type of fabric, including woven or non-woven. The welding portion integral with the fabric can extend either partially or completely over the width of the fabric. The welding portion of the fabric comprises at least a warp or a weft, or both, which melts under hot pressing to adhere the fabric to a substrate. The substrate may be any substrate which can be subjected to hot pressing, such as a cloth sheet, a synthetic resin sheet, or the like. [0024]
[0025] The fabric for welding can be in the form of a belt, sheet, or any form of fabric, woven or non-woven. Where the fabric is woven, any type of weave can be used. Examples of types of weaves, which examples are solely for purposes of illustration and are not intended to be limiting, are twill weave, satin weave, plain weave, and the like. Any type of weaving machine can be used to produce the fabric [0025]
[0026] The welding portion of the fabric can be any type of material which flows under hot pressing conditions to form a seal between the welding fabric and a substrate. The welding portion of the fabric may comprise warp or weft fibers coated with a thermoplastic synthetic resin, such as polyvinyl chloride, which melts under conditions of hot pressing to seal the fabric to a substrate. Alternatively, the warp or weft per se can be coated with a thermoplastic synthetic resin which melts under conditions of hot pressing to seal the fabric to a substrate. [0026]
[0027] Referring to FIG. 1, the fabric for welding [0027] 1 is in the form of a belt which is twill-woven from warp 1 a and weft 1 b using a needle loom. In this embodiment, one side of the fabric for welding is reinforced by chain-knitting an edge thread 1 c.
[0028] The belt-form fabric for welding [0028] 1 is divided widthwise into a welding portion A and a fixing portion B. The warp 1 a in the welding portion A is coated with a thermoplastic synthetic resin such as PVC. In this embodiment, only the warp 1 a is coated. However, the weft 1 b may also be coated, or may be coated instead of the warp 1 a, as long as this coating does not adversely affect weaving of the fabric.
[0029] When the welding portion A of the fabric for welding [0029] 1 is overlapped on the fringe of a substrate S and hot-pressed, the thermoplastic resin around warp 1 a melts and flows around between the substrate S and the welding portion A, adhering welding portion A securely to the surface of sheet 1. As a result, the fabric for welding 1 is perfectly welded with substrate S, thus rigidly uniting both members.
[0030] Any type of fiber can be used for warp [0030] 1 a and weft 1 b, including spun yarn, filament yarn, and textured yarn. The yarns can be made of any suitable material for making fabrics, including natural fibers, synthetic fibers, and blends thereof.
[0031] Where warp [0031] 1 a comprises a multi-fiber assembly such as spun yarn, multi-filament yarn, or the like, some of the components of the yarn can be fibers coated with a thermoplastic synthetic resin or can be thermoplastic synthetic fibers per se. The weft 1 b can also be composed in the same way as the warp 1 a.
[0032] FIG. 3A shows an embodiment of the present invention in which the fixing portion B of the fabric for welding [0032] 1 is provided with auxiliary fixing means. In FIG. 3A, holes H are bored at a suitable interval in the fixing portion B in the fabric for welding 1 to facilitate fixing the unit to another unit or to a column, etc., using a rope or cord or similar device threaded through the holes.
[0033] FIG. 3B provides another example of auxiliary fixing means in the fixing portion B of the fabric for welding [0033] 1 is provided with straps U, such as those disclosed by Unexamined Patent Publication H7-207-547.
[0034] In the above examples, a welding portion A is shown on one side of the fabric for welding [0034] 1. The welding portion A can be made on both sides of the fabric for welding 1 as shown in FIG. 4A, or can be made the middle part of the fabric, as shown in FIG. 4B. Also, auxiliary fixing means such as straps can also be provided where desired.
[0035] In the above examples, the fabric for welding [0035] 1 has been in the form of a belt. However, if necessary, the width of the belt can be broadened, and the fixing portion can be extended to that it may completely replace the substrate S. The fabric for welding with an extended fixing portion can be welded with another fabric for welding, as shown in FIG. 5.
[0036] In the examples described so far, the fabric for welding [0036] 1 has been divided into a welding portion A and a fixing portion B. However, the entire portion of the fabric for welding 1 can be made as the welding portion A. FIG. 6A illustrates a fabric for welding in which an entire welding portion A is overlapped on the fringe of a substrate S. Optionally, holes (not illustrated) can be bored in this welding portion.
[0037] FIG. 6B provides another example where the fabric for welding is connected with two substrates S. [0037]
[0038] FIGS. [0038] 7A-C illustrate some three-dimensionally woven fabrics for welding 1. FIG. 7A shows an example where two welding portions A are branched from the middle line of a belt-form fixing portion B. FIG. 7B shows an example where two welding portions A are each branched from a line just apart from the middle line of a fixing portion B. FIG. 7C illustrates an examples wherein one welding portion A is branched from the middle line of belt-form fixing portion B.
[0039] FIGS. [0039] 8A-C illustrate other varieties of three-dimensional fabrics or welding 3. FIG. 8A shows a case in which two welding portions A are branched from one edge of a belt-form fixing portion B. FIG. 8B shows a case in which two fixing portions B are connected edge-to-edge with each other, and two welding portions A are branched therefrom. FIG. 8C illustrates a case in which two fixing portions B are connected edge-to-edge with each other, and a single welding portion A is branched therefrom. The three-dimensional weaves in FIGS. 8B and 8C have the same basic construction as those shown in FIG. 7A and FIG. 7C, respectively, but they differ in the mode of the weave. The weave compositions of the three-dimensional fabrics in FIGS. 7A-C and FIGS. 8A-C are described in detail in the specification of Japanese Patent Application H8-91782.
[0040] In a fabric for welding according to the present invention, the fabric has a welding portion and a fixing portion thereon. The welding portion uses at least a warp or a weft coated with a thermoplastic material, or a warp or a weft comprising a fiber coating with a thermoplastic material. Therefore, the fabric for welding of the present invention can be used for easy and perfect welding to substrates. [0040]
[0041] The foregoing description of the specific embodiments will so fully reveal the general nature of the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without undue experimentation and without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments.
