Abstract (en)
[origin: WO8906714A1] A spherical fibre aggregate, useful in particular as a filling material for covers, such as bed-covers, pillows, or similar, is composed of fibres and/or threads wound into a sphere to form essentially a fibre ball. To improve the properties of the fibre aggregates so that they can be used as a filling material in covers, such as bed-covers, pillows, and similar, the fibre balls are composed of a mixture of fibres, some having a greater modulus of elasticity than others. The fibres having a greater modulus of elasticity may taper lengthwise.
