The Fil Au Chinois cotton threads are singed and mercerised. When a thread is singed, it is passed through a gas flame which removes all the fluff and makes it smooth. Mercerisation is a process involving treating the thread with a caustic soda solution, which makes it easier to dye, shinier and more resistant to rotting.
