Wool scales are opened by hot-water wetting. The wool fibres then interlock and tangle, shrinking through repeated mechanical kneading, rolling, beating, and squeezing. Under continuous pressure, the fibres are densely compacted to form non-woven, glue-free felt boards with a tightly structured build.
