Basic Element of Woven Design (Drafting, Lifting & Denting Plan)
Drafting, Lifting & Denting Plan
Drafting plan : The process of drawing the warp yarn through the eye of heald frames according to design is called drafting ,and the plan which indicates how drafting needs to be done is called drafting plan. It also denotes the number of heald shaft required for a given weave repeat.
Lifting Plan : Lifting Plan defines the selection of heald frames to be lifted or lowered on each successive insertion of weft yarn. In a lifting plan the vertical spaces indicate the heald shafts and the horizontal spaces indicate the picks. The lifting plan is drawn at the right side of the weave plan.
Denting Plan : The process of inserting warp threads or ends through the dents of reed is called denting and the plan that indicate the order in which denting is done is called denting plan. Usually two yarns are passed through each dent.
Method of Indicating of Drafting Plan
By ruling line
By design paper
By ruling line : Ruling line in which the horizontal lines represent the healds and vertical lines indicate the warp threads. The marks on the line indicate the healds upon which the respective threads are drawn.
By design paper : Design paper method in which the horizontal lines represent the healds and vertical lines indicate the warp threads. The cross marks are inserted upon the small squares which indicates the thread are passed through respective heald shaft.
By numbering : Numbering method in which the heald frame number is written below the warp yarn in a weave design. This numbers indicate the number of heald shaft.
