More Information
Summary:The invention relates to a disposable hygiene article (2), surgical covering item, or surgical garment, such as an incontinence diaper, incontinence pad, surgical drape, or surgical coat, comprising a composite nonwoven fabric (38) that is provided with at least one nonwoven fabric component (16) and another nonwoven fabric or foil component (10, 12). The first nonwoven fabric component (14) is attached to the other nonwoven fabric or foil component (10, 12) in at least some areas by means of a joining pattern (36) encompassing discrete ultrasonic welding points (30) in order to form the composite nonwoven fabric (38). The joining pattern (36) extends in a first direction (32) and a second direction (34) that runs perpendicular thereto, the distance in the first direction (32) being longer than the distance in the second direction (34). At least some sections of the joining pattern (36) are not rectilinear. In order to make the formation of the welded joint a secure process, the joining pattern is embodied such that the maximum index (I) of variation of the area seized by the ultrasonic welding points is 40 percent. The invention further relates to a method for producing such a hygiene article.
