The principle of making wool felt

- Jun 27, 2018-

Wool felt is after the "felt" of the wool. According to the principle, wool felting process is divided into two types: needle felt and wet felt (P6-P7). The appearance of soft wool is covered with many scales that we can not see with our naked eyes. When these scales meet hot water, they will open and erect. If the extrusion, friction and rubbing of the external force will make the scales entangled and tightly contract together to become felt, this is the basic principle of "wet felt".


In addition to the wet felt, we can also use a special kind of wool needle to stab the wool continuously, which also makes the scales of the wool entangled with each other to achieve the felt effect, which we call the "needle felt".
