The multi-layer nonwoven is composed of at least a spun bonded layer (10) and a blow melt layer (12), bonded together by heat embossing. The nonwoven, while at a temp. close to the softening temp. of the fibres in the spun bonded layer (10), is drawn to draw the fibres of the spun bonded layer (10) and orient the fibres of the blow melt layer (12) to a max. of the orientation reserve of the fibres in the blow melt layer (12). Also claimed is a mfg. process where the multi-layer nonwoven is heated close to the softening temp. of the fibres in the spun bonded layer. It is drawn to draw the fibres of the spun bonded layer and orient the fibres of the blow melt layer to max.. their orientation reserve. |
