Study Notes
Derivatives of Twill Weave
- Twill weave structures are derived from the basic twill weave
- Common derivatives include: Pointed Twill, Herringbone Twill, Combined Twill, Broken Twill, and Elongated Twill
Pointed Twills
- Formed by combining right and left-hand twills on specific numbers of ends
- Calculations for ends and picks:
- Ends = R + L (where 'L' is the number of left-hand twill ends and 'R' is the number of right-hand twill ends)
- Picks = # of Threads of Twill Factor (calculated from the twill pattern)
- Example: A 3/1 twill with 4 ends right and 4 ends left, will have 8 total ends and 4 total picks (3 + 1)
Herringbone Twills
- Similar to pointed twills, but the twill direction is reversed at the point of change
- Calculations for ends and picks:
- Ends = L + R (where 'L' is the number of left-hand twill ends and 'R' is the number of right-hand twill ends)
- Picks = # of Threads of Twill Factor (calculated from the twill pattern)
- The twill direction changes at the point of reversing and the twill factor is reversed, unlike in pointed twill where the factor remains same
Combined Twills
- Formed by combining two or more twills within one design
- Ends calculation: LCM of the twill factors X number of twills
- Picks calculation: LCM of the twill factors
- Example: Combining 3/1 and 2/2 twills (LCM of 4 and 4 is 4. Hence, Ends=4x2=8, Picks=4)
Broken Twills
- Deliberately breaks the diagonal line of the twill weave for aesthetic effects
- Common methods include: Reversing method and Entering & Skipping method
- Reversing Method: Reverses the twill draft in groups; to calculate, LCM of twice the reversing unit and the threads of twill is calculated for the ends
- Entering & Skipping Method: Enters and skips threads from an ordinary twill; the ends calculation is based on the entering factor multiplied by the threads of twill
Elongated Twills
- Diagonal line runs at an angle other than 45° with horizontal
- The angle is determined by the thread densities (ends/inch and picks/inch) and the twill weave construction
- Angle calculation: Tan θ = Ends Per Inch / Picks Per Inch
- For determining the angle a specific thread density is required with the assumption that the warp and weft thread densities are same.
- Alternatively, if the warp and weft thread densities are different then, Tan θ = Ends Per Inch x Upward Factor / Picks Per Inch x Outward Factor.
