In the upper warp - lower weft connection system, the lower wefts pass over the upper warps only at the specified points, ensuring the binding of the upper and lower fabrics.
Since the drawing of double-layered knits with upper warp-lower weft connection consists of two different warp groups, group drawing-in is appropriate. 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 should be included. For this reason, the first two threads are generally preferred.

drawing of a double-layered fabric weave with upper warp-lower weft connection, with a ratio of 1/1;
First, the report area is determined. 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.

Lifting sign ( / ) is drawn on the squares located at the intersection points of the upper warps and lower wefts.
The points where the upper warps will rise above the lower wefts are determined. Removal marks on the specified ports are canceled.
Connection points are shown as empty squares on the mesh.
