Weft is a basic component used in weaving to turn yard or loom into fabric. The transverse weft is drawn through and inserted over and under the warp. A single thread crossing the warp is called a pick.
According to Wikipedia,
Because the weft does not have to be stretched on a loom the way the warp is it can generally be less strong. It is usually made of spun fibre, originally wool, flax and cotton, today often of synthetic fiber such as nylon or rayon.
The weft is threaded through the warp using a “shuttle“, air jets or “rapier grippers”. Hand looms were the original weaver’s tool, with the shuttle being threaded through alternately raised warps by hand.
Nickzom Calculator calculates a bunch of calculations in Polymer and Textile Engineering and shows the steps (workings), formulas and answers. Today, I would showing you with pictures how The Calculator Encyclopedia can calculate the Weft Weight in Kilograms (Kg).
