Manufacturing Process: Sorting


The material, now "ultra-clean" according to the IDFB definition, is automatically transferred from the washing lines to the sorting machines.

This natural sorting, which requires a specific and rigorous know-how, makes it possible to obtain various sizes classed into 3 main categories:

Feather / Small, fine feathers / Down
