Study Notes
Derivatives of Twill Weave
- Twill weaves create a diagonal pattern, and various derivatives alter this basic pattern.
- 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 ends.
- Calculation of ends and picks involves the reversing unit and threads of twill factor.
- Ends = R + L (where R = number of right hand twill ends, and L= number of left hand twill ends)
- Picks = # threads of the twill factor
- Example: 3/1 twill with 4 ends right and 4 ends left results in 8 total ends and 4 total picks.
Herringbone Twills
- Similar to pointed twills, but twill direction reverses at the point of change.
- Ends = L + R (where L = number of left hand twill ends, and R = number of right hand twill ends)
- Picks = # threads of the twill factor
- Twill factors reverse when twill direction changes.
Combined Twills
- Formed by combining two or more twills within the same design.
- Calculate ends and picks using the least common multiple (LCM) of the twill factors.
- Ends = LCM of twill factors x # of twills
- Picks = LCM of twill factors
Broken Twills
- The diagonal line of the twill is purposely broken to create attractive patterns.
- Created using two main methods:
- Reversing Method: Regular twill broken by reversing its design in sets.
- Ends: LCM of (2 x Reversing Unit) & Threads of Twill
- Picks: Threads of Twill
- Entering and Skipping Method: Entering and skipping threads in an ordinary twill.
- Ends: Entering Factor x Threads of Twill
- Picks: Threads of Twill
- Reversing Method: Regular twill broken by reversing its design in sets.
Elongated Twills
- The angle of the diagonal line in these twills varies from the 45° angle of regular twills.
- Angle formation depends on:
- Thread densities (ends per inch, picks per inch).
- Formula: Tan θ = Ends Per Inch / Picks Per Inch.
- Design of the twill weave (Special methods) -Formula: Tan θ = Upward Factor / Outward Factor
- Thread densities (ends per inch, picks per inch).
