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
Zig-zag and Herringbone Twill Weave
Zigzag twill are those in which the direction of twill is frequently reversed at suitable intervals either across the width or along the length. Herringbone twill are those in which the direction of twill is frequently reversed at suitable intervals either across the width or along the length but not as zig-zag twill and weft yarns floating condition is reversed of the previous yarn.
Diamond Design | Diaper Design
Diamond design is constructed on the principle of zig-zag twill.Pointed draft is used to make diamond design.Diaper design is constructed on the principle of herringbone twill.Straight or broken draft is used to make diamond design.

Drawing, Texturing, Intermingling and Heat setting Process
Man Made Fibre and Man Made Fibre Production - Manufactured (MF) fibers (formerly termed “man-made”) are formed from a suitable raw material as a thick, sticky liquid, which is “spun” or extruded through spinneret holes, forming streams that are solidified into fibers.
Woven fabric Structure
The order of interlacement of warp and weft threads at right angles is known as structure of woven fabrics. The interlooping system of yarns is known as structure for knit fabrics. Classification of woven fabric structure: Simple structure and Compound Structure.Methods of fabric representation:❶Warp overlap in which warp is above weft and ❷Weft overlap in which weft is above warp
