Abstract (en)
[origin: EP0277494A2] There is described a spherical fibre aggregate, in particular for use as a fill or upholstery material, composed of fibres and/or filaments which have been spherically coiled and which essentially form a fibre ball. To devise congeneric fibre balls which possess better properties, in particular for use as fill material, it is proposed that the fibre balls shall comprise a mixture of main fibres and binding fibres. The binding fibres shall have been bonded to the main fibres at cross-over points. <??>In one embodiment, the binding fibres are two-component fibres, in which one component has in particular a high modulus compared with the other component and preferably only one of the components has a binding action. <??>the binding fibres ensure a three-dimensional network of all the fibres in the fibre balls.
