Shadow twill painting method:
1. Select the bottom arrangement: use the original arrangement of twill as the base arrangement (the arrangement of the bottom arrangement is R0);
2. Determine the scheduling cycle:
First find the number of transitions = R0-1
For warp shadows: Rj = R0 (R0-1)
Rw = R0
For latitudinal shadow twill: Rj = R0
Rw = R0(R0-1)
3. The warp twill is drawn on the Italian paper in the horizontal direction (R0-1), and the bottom is arranged in the first cycle, and then in each cycle, in the vertical or horizontal direction next to the twill arrangement point. Increment an arrangement point; the latitudinal shadow twill draws the (R0-1) root cycle in the longitudinal direction, fills the root arrangement in the first cycle, and then sequentially increments in the vertical or horizontal direction next to the twill arrangement point in each cycle. A point of arrangement.
The surface of the shadow twill fabric exhibits an appearance effect from light to dark or from dark to bright. In jacquard fabrics, the shadow level is often arranged by a shadow twill.
Strengthening the twill and compound twill is the most fundamental change of the twill, and the other changes the twill to strengthen the twill and the composite twill as the root twill.
