Point Draft And Broken Draft
Properties of Point Draft or V-Draft
The following are properties of point draft or V-draft. They are-
- Point draft is used for woven structures that are symmetrical about the center. They are frequently employed to produce a diamond effect.
- Generally, it is used where the straight draft cannot be applied because of a large repeat.
- The point draft can be considered as a combination of straight drafts, constructed firstly in one direction and then in another.
- The change in direction takes place on the first and last shafts of the draft which are the point of reversal.
- The first and last shafts carry only one end each whilst all the heald shafts in the middle carry two ends per repeat of the draft.
- So, the number of ends per repeat of the design is calculated as = (2 x Number of heald shaft) – 2.
Properties Of Broken Draft
The following are properties of the broken draft. They are-
- Firstly, the broken draft can be considered as a modified Point draft.
- This is a combination of straight drafts with different directions of construction.
- But the direction is reversed not on the last or the first shaft. When the direction is reversed, the first thread of the next group is started higher or lowers than the last thread of the proceeding group.
- Herring Bone Twills, Diaper design and some other weave is produced by applying this broken draft.
So, that’s all about point draft and broken draft.
