- exactly four lower longitudinal threads 33, 34, 35, 36 are arranged between the two functional pairs 21, 22 and 23, 24.
- transverse threads 101 to 112 are assigned to the upper fabric layer and eight transverse threads 201 to 208 to the lower fabric layer.
- the twelve transverse threads 101 to 112 of the upper layer have a smaller diameter than the eight transverse threads 201 to 208 of the lower layer.
- the twelve transverse threads 101 to 112 of the upper layer have a smaller diameter than the eight transverse threads 201 to 208 of the lower layer.
- Cross threads 101 to 112 are formed as upper transverse threads and extend exclusively in the upper fabric layer, and the eight transverse threads 201 to 208 are formed as lower transverse threads, which extend exclusively in the lower fabric layer. That is, none of the transverse threads 101 to 112 change to the running side and the lower fabric layer, respectively, and none of the transverse threads 201 to 208 change to the paper side and the upper fabric layer, respectively. It is noted that the
- Transverse threads e.g. equal to or greater than the diameter of the lower transverse threads.
- Course of the upper composite longitudinal thread 21, 22 is opposite the course of the upper longitudinal thread 11 offset by exactly one upper transverse thread.
- the upper longitudinal thread 12 and the upper composite longitudinal thread 23, 24 have the same course as the upper longitudinal thread 11, and the course of the upper longitudinal threads 13 and 14 corresponds to the course of the upper composite longitudinal thread 21, 22nd
- each of the upper longitudinal thread and upper composite longitudinal thread binds every other upper transverse thread in the
- each of the eight lower longitudinal threads 31 - 38 runs alternately above and below a lower transverse thread and thereby binds exactly four lower transverse threads.
- the lower longitudinal threads 31 - 38 runs alternately above and below a lower transverse thread and thereby binds exactly four lower transverse threads.
- Transverse threads 201, 203, 205 and 207 i. the course of the longitudinal thread 32 arranged adjacent to the longitudinal thread 31 is offset by a transverse thread.
- the course of the longitudinal thread 33 arranged adjacent to the longitudinal thread 32 corresponds to the course of the longitudinal thread 32, and the course of the
- longitudinal thread 34 corresponds to the course of the longitudinal thread 31st
- the formed by the lower longitudinal threads 31, 32, 33 and 34 4-shaft binding is through the lower longitudinal threads 35, 36, 37 and 38th repeated.
- the running side 4-shaft binding repeats after four lower transverse threads. In other words, in FIGS. 10 and 10a, four repeats of the running side four-shaft binding are shown. Each running cross weave repeat binds each lower cross thread twice.
- an upper longitudinal thread is always arranged between two lower longitudinal threads in the plan view of the fabric.
- the upper longitudinal thread 11 lies in the plan view substantially between the two lower longitudinal threads 31, 32 (see Figure 11)
- the upper longitudinal thread 12 is substantially between the lower longitudinal threads 33, 34
- the upper longitudinal thread 13 is substantially between the lower longitudinal threads 35, 36
- the upper longitudinal thread 14 is substantially between the lower longitudinal threads 37, 38th
- the diameter of the upper longitudinal threads 11-14 may be equal to the diameter of the threads 21-24 of the functional pairs. This can be a
- the upper longitudinal threads 11-14 and the threads 21-24 of the functional pairs can be easily arranged on a common warp beam (e.g., warp beam X2 in Fig. 8).
- the diameter of the lower longitudinal threads 31-38 may be e.g. like that
- the fabric according to the second embodiment can be produced like the fabric according to the first embodiment with the loom or warp thread arrangement shown in FIG.
