Fibrous polyolefin nonwoven sheets are bonded and stretched in a continuous, multiple stage process. First, the sheet is heated without significant stretching to a temperature that is close to, but below, the melting temperature of the polyolefin. Then, as the sheet is forwarded to a first stretching stage, the sheet temperature is decreased by 5 DEG to 40 DEG C. and thereafter the sheet is alte...
