And then, weave silk by hand loom or power loom. The threads will be woven at right angles to each other, and the two different angles are called a warp and a weft. The third scene shows the process of spooling. The basic weaving technique uses the same or different colors in the warp and weft threads. On average, 36,000 worms consume 1 ton of mulberry leaf over their lifetime. The protein fiber of silk is composed mainly of fibroin and is produced by silkworms larvae to form cocoons.
