  • the present invention relates to a textile material that has improvements in relation to textile materials.
  • Some embodiments relate to textiles that offer thermal stability and to a method of forming said textile materials.
  • Textiles are known in the art and are formed from interlacing yarns to produce a flexible material. Properties of textile materials can differ greatly by using different yarns (such as colours, materials, thickness) and by using different interlacing techniques (such as weaving, knitting, crocheting). Furthermore, each of these techniques has a large number of variations. In this manner, textiles can be produced for a wide variety of different end uses.
  • a textile made for outer wear may be required to have an element of weather resistance, whereas a textile made to contact the skin may be required to be soft on the wearer's skin. It is an object of some aspects of the present invention to provide an improved textile material. It is an object of some aspects of the invention to provide an improved method of forming a textile material.
  • aspects of the present invention provide a method, a textile, an article such as a curtain, a cushion cover, a pillow case or a garment and a loom.
  • a method of forming a textile material comprising weaving, in a single weaving operation, a first layer, the first layer comprising a warp comprising warp threads and a weft comprising weft threads, and a second layer, the second layer comprising at least a weft comprising weft threads, the single weaving operation comprising joining the second layer and the first layer by weaving as the material is woven.
  • Embodiments of the invention enable a textile to be fabricated in which two or more layers of material are joined during the weaving operation without a requirement to perform a post-weaving joining operation.
  • the first and second layers may therefore be considered to be joined in a substantially seamless manner.
  • the method may comprise weaving the weft of the second layer with the warp of the first layer to join the first and second layers.
  • the method may comprise weaving the weft of the second layer with the warp of the first layer at a plurality of locations across the warp of the second layer.
  • This feature has the advantage that in the case the second layer comprises a weft and not a warp, sagging of the weft threads across the second layer may be prevented. This is because the weft threads of the second layer are stitched to the warp of the first layer by interweaving with the warp threads.
  • the region in which the interweaving is provided may be referred to as an integrally woven seam.

  • the textile may be formed to be suitable for a range of applications including the manufacture of jackets, trousers, sleeping bags, upholstery and any other suitable articles or applications.
  • the method may comprise weaving the weft of the second layer with the warp of the third layer at a plurality of locations spaced apart across the weft of the second layer.
  • the weft of the second layer is only compressed by the weaving at the spaced apart locations. This allows the portion of the weft between spaced apart locations to remain substantially uncompressed. It is to be understood that in the case the weft is arranged to trap air therein in order to enhance a thermal insulation characteristic thereof, compressing of the weft may compromise the thermal insulation characteristics thereof.
  • a region in which two layers are joined by weaving the weft of one layer with the warp of another may be referred to as a seam, the seam being integrally formed as part of the weaving operation by which the layers are formed.

  • a transition from weaving a single layer to weaving a double layer may be made followed by a transition substantially seamlessly back to weaving a single layer.
  • a tube of fabric a wall of which is provided by the first and second layers may thereby be fabricated. It is to be understood that the transition from the common layer to the first and second layers may be considered to be substantially seamless in some embodiments since a requirement to join the first and second layers in a post-weaving finishing operation may be eliminated.

  • FIG. 5 shows a pocket 1 10 in cross-section as viewed in a direction perpendicular to the warp threads. It can be seen that in the example shown a first layer of fabric 107F forms a front layer of the pocket 1 10, a second layer 107R forms a rear layer and a third layer 107FL forms a flap layer behind the second layer 107R that helps to prevent padding from falling out of the pocket 1 10. It is to be understood that the front and rear layers 107F, 107R are joined along a basal edge 103B and side edges 103S (shown dotted) of the pocket 1 10. The front and flap layers 107F, 107FL are joined along a head edge 103H opposite the basal edge 103B and along side edges of the flap layer 107FL. Arrow P shows a path along which padding may be inserted into the pocket 1 10. The pocket 1 10 is shown prior to being turned inside out, if required.
  • FIG. 6 shows a length L of textile 201 according to a further embodiment of the invention.
  • the textile 201 has been woven to form pockets 210 similar to those of the embodiment of FIG. 4 except that the third layer 107FL has been omitted.
  • a flap portion 207FL (FIG. 4) is provided by extension of front layer 207F beyond a boundary of rear layer 207R. The flap portion is formed by region 201 A of the textile 101 (FIG. 6).
  • the front and rear layers are not substantially coextensive, the front layer 207F extending beyond a border of the rear layer 207R in one direction.
  • the front and rear layers 107F, 107R are substantially coextensive.
  • the flap 207FL is arranged to be folded back and tucked between the front and rear layers 207F, 207R in order to prevent padding from falling from inside the pocket 210. It is to be understood that pocket 210 shown in FIG. 7 may be turned inside out in order to hide any portions of the single layer 201A that might otherwise be visible.
  • Edge 205 shown in FIG. 6 and FIG. 7 is a free edge of rear layer 207R.
  • the pocket 210 may be arranged to be around 10 inches square with a 6 inch flap extending laterally from the opening between front and rear layers. Other dimensions are also useful.
  • FIG. 8 shows a draft and peg plan for a cushion cover according to an embodiment of the present invention, implemented using eight shafts. Other numbers of shafts are also useful and embodiments of the invention are not limited to eight shafts.
  • garments such as dresses, shirts, T- shirts, blouses, trousers and the like can also be fabricated.
  • Garments may be fabricated with substantially no joining operations required. In some embodiments garments may be fabricated with fewer joining operations than might otherwise be required.
  • a number of other articles may benefit from being fabricated according to embodiments of the present invention including cloth for sails for marine vessels where pockets for battens and the like may be required, tents, awnings, gazebos and a host of other applications.
  • fabrics used in some embodiments, in particular face fabrics viewed by a user may for example be of a woven design and piece dyed. The face may for example be polyester, with a cotton lining.
  • the polyester and cotton could be dyed to two different colours in the same dye bath.
  • the threads in the warp and weft could be dyed before weaving and there could therefore be no restriction on the type of fibre used in some embodiments.
  • the cotton back or lining might for example first be dyed to a beige or neutral colour, and the face prepared for transfer printing. Substantially any design can then be printed onto the face.
  • FIG. 9 (a) is a plan view of a length of a fabric 301 according to a further embodiment of the invention suitable for manufacture of a curtain.
  • the fabric 301 is woven in such a manner as to incorporate alternate stripes 322, 324 of a hook yarn and a loop yarn respectively across a width thereof.
  • the positions of the hook stripes 322 and the loop stripes 324 may be reversed in some embodiments.
  • the stripes 322, 324 may be on the same or opposite sides of the fabric 301.
  • the stripes 322 of hook yarn are provided at repeat intervals of length L1 as the fabric 301 is woven and the stripes 324 of loop yarn are provided a distance 2(L1 -L2) from the stripes 322 of loop yarn.
  • the fabric 301 may be cut at intervals of length L1 after weaving, for example along line A-A in order to form lengths of curtain material 301 C as shown in FIG. 9(b).
  • the material 301 C may then be folded along line B-B and the hook stripes 322 and loop stripes 324 coupled to one another as shown in FIG. 9(b). It is to be understood that this enables a reduction in a hung length of the curtain material 301 C from L1 to L2.
  • the presence of the hook and loop stripes 322, 324 enable a user to conveniently reduce the length of the curtain material 301 C without cutting.
  • a lower edge 301 CL of the material 301 may therefore be made more aesthetically appealing because it is formed by a crease or fold rather than a cut.
  • edge 301 CL may be made more aesthetically pleasing by pressing, for example with a press or iron.
  • a yarn comprising a heat activated adhesive may be incorporated into the material 301 C.
  • the yarn may be incorporated such that cut line A-A bisects or otherwise divides the region in which the yarn comprising heat activated adhesive is incorporated. It is to be understood that after cutting along line A-A, one or both free ends of the material 301 C may have a stripe or other portion of heat activated adhesive provided thereat depending on the location of line A-A. Thus one or both free ends may be folded over and the heat activated adhesive activated to form a hem in a convenient manner, for example by pressing with an iron.
  • the material 301 C may be formed such that lower stripe 324 is a sufficient distance from the line A-A along which the fabric 301 is cut to allow the yarn comprising heat activated adhesive to be provided in the region between stripe 324 and line A-A. This allows a lower edge of the length of curtain material 301 C to be hemmed in a convenient manner. It is to be understood that if it is required to shorten the length of curtain material 301 C the material 301 C may be folded along line B-B to form a new lower edge 301 CL.
  • FIG. 7 shows an example of a piece of curtain material 401 C having three repeat units of hook stripe 422 and loop stripe 424 woven therein, and a stripe 426 that includes a heat activated yarn.
  • the respective stripes 422, 424 are substantially adjacent one another, sharing a common boundary.
  • the respective stripes 422, 424 may be spaced apart from one another, or respective repeat units of stripes 422, 424 may be spaced apart.
  • more than one respective hook stripe 422 and more than one respective loop stripe 424 may be coupled together depending on where the material 401 C is folded.
  • a hem may be formed by folding the material and coupling respective hook and loop stripes 422, 424 at a plurality of locations without a requirement to incorporate into the material 401 C the stripe 426 that includes the yarn comprising heat activated adhesive.
  • the stripe 426 is provided at or close to a free edge of the material 401 C. Other arrangements are also useful.
  • embodiments of the present invention enable incorporation of hook yarn or loop yarn into a fabric as the article is being woven.
  • hook and loop fastenings of the Velcro (RTM) type may be incorporated into an article directly without a requirement for post-weaving stitching or gluing of hook and loop tape into the article. A substantial reduction in finishing costs associated with an article may therefore be enjoyed.
  • FIG. 10 shows a fabric 501 in which a T-shirt garment 510 has been woven.
  • the fabric 501 is formed from a single layer of material, except in the shaded region 510 where the fabric is double layered.
  • the fabric 501 may be cut through the single layer around and close to the border of the garment, e.g. along the dotted line shown in FIG. 1 1 after weaving in order to separate the garment 510 from the remainder of the fabric 501 .
  • Free edges 510 may be formed in the garment 510 to allow the garment 510 to be turned inside out and worn by the user. In some arrangements the edges 510 may be formed by cutting. Hems may then be formed if required. In embodiments where yarn comprising heat- activate adhesive has been provided in the garment 510 hems may be formed by folding the fabric and applying heat and pressure. Other arrangements are also useful.
