Abstract (en)
[origin: US4820574A] A filler material for cushions and covers, in particular with spherical fiber aggregates wherein individual cut fibers are intertwined, is described. The fiber aggregates are capable of forming connections with others parts of the filler material. The connection is burr-like and is releasable. This may be obtained, for example, by the individual fiber ends (3) which project from the surface of the otherwise spherical fiber aggregate (1). In this manner a filler material for cushions and covers is obtained, in which the fiber aggregates do not shift or slide excessively within a covering, in particular a pillow, so that an adequate and permanent support for the head of a person is provided.
