Description

[0050] The FIGURE shows in this case a fabric 10, which is in particular used as a fabric for a double blind. In this case, the fabric 10 comprises a plurality of sections, wherein in the FIGURE, one shading section 20 and two translucent sections 30 are formed. Actually, a fabric has both a plurality of shading sections and a plurality of translucent sections formed in between them.

[0051] In the translucent section 30, the fabric has first weft threads 31 arranged substantially in parallel to one another at a desired lattice distance. Furthermore, standing threads 35 and leno threads 39 can be recognized. One standing thread 35 and one leno thread 29 form a warp thread pair 40 in each case.

[0052] In the represented example, both the standing threads 35 and the leno threads 39 are made of a crystal-clear transparent monofilament. In the translucent section 30, the leno threads 39 are arranged such that they intertwine the first weft threads 31 and the standing threads 35 in the manner of a leno fabric. The crystal-clear transparent monofilament may be, for example, 56 dtex PES. The use of this material is also possible in other embodiments that are independent of the represented FIGURE.

[0053] The translucent sections 30 have corresponding lattice openings 50. Together with the material of the standing threads 35 and the leno threads 39, the lattice openings 50 contribute to the translucent effect.

[0054] In a particularly preferred embodiment of the invention, the first weft threads 31 are formed of a meting filament yarn, in particular a PES melting filament yarn having 50 dtex, for example. The use of this material is also possible in other embodiments that are independent of the represented FIGURE.

[0055] In the shading section 20, the leno threads 39 are no longer arranged to be contorted but run substantially in parallel to the standing threads 35. No loops and no (large) lattice openings are formed.

[0056] Between the standing and leno threads running in parallel, second weft threads 22 are woven in. It can be recognized that the second weft threads 22 are made of a material which differs from that of the first weft threads 31. Furthermore, the material thickness of the second weft threads 22 is many times larger than the material thickness of the first weft threads 31.

[0057] In the interwoven state, the second weft threads 22 adjoin each other. For reasons of representation, this cannot be illustrated exactly in the FIGURE. However, it is clear that the shading section 20 is formed to be by far more opaque and less translucent than the translucent sections 30.

[0058] Furthermore, it can be recognized that the shading section 20 has a larger extension in the longitudinal direction L of the fabric 10 than the translucent sections 30. When the fabric 10 is used as a double blind fabric, this allows a shading section 20 to be positioned or arranged in front of a translucent section 30 so that the translucent section 30 can be completely covered by a shading section 20.

[0059] A translucent section 30 following the shading section 20 further below, in turn has the standing threads 35 and the leno threads 39 which extend, starting from the translucent section 30 formed above, across the shading section 20 up to the next translucent section 30.

[0060] The represented fabric 10 is produced according to the invention on a leno loom.
