Feather-based padding product, preparation method and installation for implementing said method

摘要

The invention concerns a feather-based padding product having a coherent shape resulting from the presence of a structure in the form of a three-dimensional network; said network consists of mutually bound thermoplastic fibres (2), which enclose said feathers. Said fibres (2) are first mixed with the feathers, then with appropriate heat treatment, said fibres are bonded at their contact points (5). The padding product is thus in the form of a web and it is packed in rolls or in the form of slabs.
