An elastic composite material is disclosed which includes at least one non- woven material layer, at least one further sheet material layer and therebetween a parallel oriented group of elastic threads. The non-woven material is thermally melt bonded with the further sheet material in the form of a predetermined pattern of melt bonding regions and the elastic threads are melt embedded in the tensioned condition at selected locations into the melt bonding regions between the non-woven material and the further sheet material. The materials of the non-woven and sheet material layers and of the elastic threads are selected such that the material of the elastic threads is not melt bonded with the materials of the non-woven and sheet material layers in the melt bonding regions. The resulting composite material can be used for the manufacture of hygiene articles, especially diapers including diaper pants.
