  • fibrillated yarn generally have a higher surface roughness that smooth and polished round yarns.
  • At least one yarn may have a higher surface roughness compared to at least one further yarn by virtue of the yarns having different, preferably opposing twist directions.

  • the at least one motif 71 and background region 70 may be formed using the Jacquard process on a Jacquard loom.
  • the at least one motif 71 may be a different visible colour to at least part of the background region 70 adjacent to the at least one motif 71 when viewed by the naked eye in reflected light incident upon the attachment layer 17.
  • the background region 70 may appear substantially as at least one first colour (e.g. white) at least partially around the at least one motif 71 whilst the at least one motif 71 may be at least one different second colour (e.g. non-white).
  • a single motif 71, or each of a plurality of motifs 71 may comprise a plurality of different colours when viewed by the naked eye in reflected light incident upon the attachment layer 17.
  • the at least one motif 71 may comprise different colours corresponding to the image or design it represents.
  • the at least one motif yarn may have a different surface roughness, hardness, stiffness and/or diameter to the at least one background yarn.
  • the at least one motif 71 can be distinguished by human touch by virtue of having a higher or lower surface roughness, diameter, stiffness and/or hardness to the at least partially surrounding background region 70.
  • a particularly preferred effect can be achieved by the at least one motif yarn having a greater diameter than the at least one background yarn, which results in the outer surface of the at least one motif 71 being raised above the at least partially surrounding outer surface of the background region 70.
  • the resulting raised texture is easily distinguishable to human touch and also creates a three dimensional effect visible to the naked human eye.
  • the effect can be further developed by having a plurality of motif yarns of different diameters such that the outer surface of the motif itself is textured with different contours, thereby forming complex three dimensional effects visible to the human eye.
  • the at least one motif 71 has a different texture to the background region 70 such that they are distinguishable from one another by human touch.
  • the presence of the at least one motif yarn in the at least one motif 71 is detectable as providing a texture distinguishable to the texture of the background region 70.
  • Such a different texture is also achieved if the at least one motif yarn and at least one background yarn have substantially the same haptic and/or optical characteristics.

  • the at least one motif 71 may extend over the fold 12. If the fold 12 is offset from the attachment means, such as by being offset from the stitch line, the at least one motif 71 may extend over the fold 12 and/or attachment means. In such arrangements the difficulty of attempting to adapt the at least one motif 71 is increased since the adaptation will require the entire removal of the security sheet 11 from the security document 10 to reach the area under the fold 12 or attachment means.
  • the at least one motif 71 may be located only in the hinge portion 26 such that it is located and visible outside of the data sheet 15. However, the at least one motif 71 may be at least partially located on the connection portion 60 and/or at least partially located within or on the data sheet 15. Thus the at least one motif 71 may be difficult to reach during an attempted adaptation.
  • the at least one motif 71 may be separated from the edges of the attachment layer 17 such that it is a discrete element entirely surrounded by the background region 70.
  • the at least one motif 71 may not extend between opposing edges of the attachment layer 17 and may be in contact with fewer than three edges of the attachment layer 17.
  • the or each at least one motif 71 may extend across less than approximately 50% of the area of the hinge portion 26, less than approximately 25% of the area of the hinge portion 26 or less than approximately 10% of the area of the or hinge portion 26.
  • the surface area of the at least one motif 71 may be less than approximately 50%, 25% or 10% of the surface area of the background region 70.
  • the at least one motif 71 may extend between opposing edges of the attachment layer 17 (in this case three edges of the attachment layer 17 and four edges of the hinge portion 26).
  • Figure 5 and 6 also illustrate how the colours of the at least one motif 71 and background region 70 can be a first colour combination on a front side (as in Figure 5 ) of the attachment layer 17 and a second colour combination, which is the inverse of the first colour combination, on a reverse side (as in Figure 6 ) of the attachment layer 17.
  • the front side motif 71 is black and the front side background region 70 is white.
  • the front side motif 71 is black and the front side background region 70 is white.
  • the reverse side motif 71 being white and the reverse side background region 70 being black.
  • Such an inverse colour arrangement can be achieved by forming a two tone damask on a Jacquard loom in which the at least one front side motif 71 and reverse side background region 70 are formed from the at least one motif yarn of the first colour and the front side background region 70 and at least one reverse side motif 71 are formed from the at least one background yarn of the second colour.

  • adjacent warps 31 form first regions of a first textile structure whilst the wefts 30 extending between the adjacent warps 31 form a second textile structure. Due to the separation being relatively large, it is possible to detect the gap or separation between the adjacent warps 31 by human touch.
