If you want to create a more realistic weaving drawing, you can use shading to create the illusion of depth. To do this, shade the areas where the warp and weft threads overlap. You can also use shading to create different textures and patterns in your weaving.

What is Weaving Drawing?
Drawing is the process of elongating filament/fiber by passing it through a series of roller pairs in plastic conditions. Each pair moves faster than the previous one.
Weaving drawing is a technique used to create the illusion of woven fabric on a two-dimensional surface. It is done by drawing a series of parallel lines to represent the warp threads and then drawing horizontal lines over and under the warp threads to represent the weft threads. The weft threads can be drawn in multiple of patterns to create different effects.
Objectives of Drawing/Effects of Drawing:
- It increases fiber strength.
- It orients polymer molecules along the filament.
- It reduces creep properties.
- It increases orientation and crystallinity.
- It removes brittleness and instability.
Types of Drawing Process:
There are 03 types of drawing processes as follows-
01. Drawing in un-plasticized condition: This process is run in the un-plasticized condition
of yarn. Example: Polyester (Terylene) and acrylic. This process is run in two ways-
a) Cold un-plasticized condition: No heater is used when Tg = Room Temp.
b) Hot un-plasticized condition: when Tg > Room Temp, a heater is used.
02. Drawing in plasticized condition: Yarn is passed through the stretching rollers
which is taken in a plasticizing bath. Example: Nylon.
03. Wet stretching: Nascent yarn is stretched. Example: Viscose rayon. This process is
run in two ways-
a) Godet controlled wet stretch: Stretched by Godet wheel directly.
b) Snubber-controlled wet stretch: Yarn is arranged with a snubber pin & stretched by
a godet roller.
