Aperturing and Hole Formation in Nonwovens
topic
Nonwoven aperturing creates defined circular or shaped holes through the fabric thickness using pin perforation, die cutting, or hydrojet aperturing to produce nonwovens with controlled open areas for improved fluid strike-through in hygiene cover stocks, increased air permeability for wound dressings, and aesthetic three-dimensional surface texture for premium wipes where aperture size, shape, and coverage determine the functional and visual characteristics.
Role
Creates the open-work structures and defined perforation patterns used in hygiene cover stocks and medical nonwovens where fluid must pass rapidly through the nonwoven surface to the absorbent core below, with aperture size and coverage area being the primary parameters governing the strike-through rate and rewet performance that distinguish premium apertured cover stocks from plain nonwoven alternatives in the hygiene product performance hierarchy.
