ABSTRACT:
A spherical fiber aggregate having an inner core and outer covering, in particular as a filler material for cushions and covers wherein individual filaments or fibers are intertwined, is characterized in that the core of the fiber aggregate contains filaments or fibers different from those of the covering. In this manner spherical fiber aggregates are created, which combine different properties, and in particular are capable of absorbing humidity when used as a filler material, and therefore contain natural fibers, while on the other hand they do not lose their down-like properties, such as high bulk, compressive elasticity, softness, thermal insulation ability, light weight and ready adaptation to the body to be covered.
