In the upper warp - lower weft and lower warp - upper weft connection system, at some points the upper warps pass under the lower wefts, and at some points, the lower warps pass over the upper wefts and connect the upper and lower fabrics to each other. Upper warp-lower weft and lower warp-upper weft Since the drawing of linked double-layered knits consists of two different warp groups, it is appropriate to draw in groups. Since the interaction of the threads of the upper fabric and the threads of the lower fabric will be examined while taking a section, both thread groups must be included. For this reason, the first two threads are generally preferred.

so that the ratio is 2/2 top warp-bottom weft, bottom warp-top weft connection double-layered fabric weave, drawing of warp and weft sections, drawing-in and dobby plans.
1-Determine the report area. For the upper and lower fabric, the warp and weft are sorted according to the given ratio. Sorting starts from the top warp and top weft.
Here;
It should be noted that there are 6 warps-6 wefts in the upper knitting pattern and 6 warps-6 wefts in the lower knitting pattern. The warp and weft ratio are taken into account when determining the report area.
2- To the squares at the intersection points of the upper warps and upper wefts.

The upper fabric weave is placed.
3- To the squares at the intersection points of the lower warps and lower wefts.
3
D ------------------- Z
3
The lower fabric weave is placed.
4-A lifting sign ( / ) is drawn on the squares located at the intersection points of the upper warps and lower wefts.
Here;
It should not be forgotten that in double-layer fabric structures, all the upper warps must be on the lower wefts.
5-The points where the upper warps will rise above the lower wefts are determined. Removal marks on the specified ports are canceled.
Here;
When selecting the upper warp-lower weft attachment points, weft domination (empty square) attention is paid. Connection points are shown as empty squares on the mesh.
6-The points where the lower warps will rise above the upper wefts are determined. The attachment points are marked on the mesh.
Burada;
When choosing the lower warp-upper weft attachment points, warp dominated (full square) attention is paid. Connection points are shown as solid squares on the mesh.
7-Drawing the warp section
Here;
According to the warp section, the 1st upper weft connects with the 5th lower warp. It connects the 2nd lower weft with the 5th upper warp.
8-Drawing the weft section.
Here;
According to the weft section, it connects the 1st upper warp with the 4th lower weft. It connects with the 1st lower warp and the 3rd upper weft.
9-Drawing the draft and dobby plan
Here;
It should not be forgotten to show the connection points on the knitting while drawing out the drawing plan.

1-Determine the report area. For the upper and lower fabric, the warp and weft are sorted according to the given ratio. Sorting starts from the top warp and top weft.
Here;
It should be noted that there are 4 warps-4 wefts in the upper knitting pattern, and 4 warps-4 wefts in the lower knitting pattern.
2- To the squares at the intersection points of the upper warps and upper wefts.

5-The points where the upper warps will rise above the lower wefts are determined. Removal marks on the specified ports are canceled.
Here;
When choosing the upper warp-lower weft connection points, attention should be paid to the weft dominance (empty square) around them. Connection points are shown as empty squares on the mesh.
6-The points where the lower warps will rise above the upper wefts are determined. The attachment points are marked on the mesh.
Here;
When choosing the lower warp-upper weft connection points, care should be taken to ensure that the surrounding is warp-dominated (full square). Connection points are shown as solid squares on the mesh.
7-Drawing the draft and dobby plan
Here;
It should not be forgotten to show the connection points on the knitting while drawing out the drawing plan.
