ABSTRACT:
A spherical fiber aggregate, in particular as a filler and cushioning material of spherically entangled fibers and/or filaments, is described. In order to provide fiber balls of this generic type, having improved properties specifically for use as a filler material, it is proposed that the fiber balls contain a mixture of principal fibers and binder fibers. The binder fibers are connected with the principal fibers at their intersections.
According to one embodiment, the binder fibers are two-component fibers, wherein one of the components has in particular a strong bearing modulus and preferably only one component has a binder effect.
Due to the binder fibers, a three-dimensionally bonded network of all of the fibers is present in the fiber balls.
