Following on previous LHT & RHT post, do you there is one more twill in the denim world? Do you know when we combine LHT with RHT, we will get Broken Twill?
Broken twill is a twill weaved in which the direction of the diagonal produced by the weft threads is reversed after no more than two passages of the weft creating a random zig-zag pattern. It is first used by Wrangler in 1964.
If the twill is woven either to LHT or RHT, it will eventually twist itself after washing due to the tension. This is why you see the outseam of some denim twisted to the front or back of the leg. And broken twill will combat this!
