ABSTRACT:
A fiber containing aggregate, for example, a filler material for covers or pillows, for cushioning or as a filter is described, together with a process for its preparation.
In order to provide an aggregate wherein the fibers are located and distributed three-dimensionally in the manner desired, and, if so desired, remain in such a distribution and which has improved properties in particular as a filler material, it is proposed to place an assembly of spherically entangled fibers and/or filaments into a form desired and to bond the fiber balls to each other.
The fiber balls are joined together in particular by means of binder fibers, which may consist of, for example, melting fibers, soluble fibers or adhesive fibers. Melting fibers have a melt-on temperature which is lower than the melt-on temperature of other fibers of the aggregate and are activated by the application of heat.
The fiber balls may be joined together by means of binder fibers located in the individual fiber balls and/or additional binder fibers placed between the individual fiber balls. Other materials may also be placed both into the fiber balls and between them.
