Combination Twills
Combination twills find extensive use in the worsted industry in the production of garment fabrics, as these weaves are capable of producing compact textures. These twills are constructed by two methods :
- End and end combination
- Pick and pick a combination
In the first method the twill weaves are combined end way and in the second method, twill weaves are combined in pick way. The designs for the different types of combination twills are shown in the figure.
In the figure A and B show the basic twill designs. In figure A is shown a 1/3 twill and B is shown a 2/2 twill and C, D and E show the design, draft and peg plan respectively. The type of draft used here is the divided draft. The heald shafts are divided into two groups, the first group controls the first design (1/3 twill) and the second heald shaft controls the second design (2/2 twill).
