A filling material for filling into articles of bedding is made by providing a plurality of discrete fiber clusters, applying a temperature stabilizing substance to the discrete fiber clusters, mixing the discrete fiber clusters with each other, and collecting the discrete fiber clusters thereby obtaining a filling material in which the distribution of the temperature stabilizing substance is substantially even. A device (1) for producing a filling material has an application station (22) for applying a temperature stabilizing substance to discrete fiber clusters, a curing station (24) for fixing the substance, a mixer (30) for mixing the discrete fiber clusters and a collecting station (32) for collecting the fiber clusters to form the filling material in which the distribution of the temperature stabilizing substance is substantially even.
A filling material for filling a textile adapted to come into contact with human skin and to provide a soft feeling to the skin, comprising a plurality of discrete fiber clusters, at least some of said plurality of discrete fiber clusters including a temperature stabilizing substance partially covering the surface of each individual fiber cluster, and/or forming islands within each individual fiber cluster thereof, wherein the plurality of discrete fiber clusters of the filling material are mixed with each other providing a substantially even distribution of the temperature stabilizing substance in the filling material.
