Holes are formed with heated pins, by hydroentangling over a patterned drum, or by perforating and then stretching the fabric. Apertured topsheets let thick fluids such as menses or loose stool pass quickly, and the holes also signal dryness to the user. Hole size, open area and clean hole edges are checked on the finished fabric.
Heard on the job
Aperturing pins on the edge are worn, so half the holes in lane one aren't opening.
