From Molecules to Thread: How Synthetic Fibres Are Made
In short: How polyester and nylon are built from small molecules into long chains, melt-spun through a spinneret and stretched for strength, and why some fibres, like polyacrylonitrile, must be spun from solution instead.
A 2:09 short film in the series “How Things Work”, narrated by intellect_voice_01.
