Advances in 3D Embossing & Aperturing Technologies for High-Performance Nonwovens in Hygiene Applications

Three-dimensional (3D) surface structuring of nonwovens—through embossing and aperturing—is an increasingly vital process for enhancing the functional performance of hygiene products. This paper presents a comprehensive review of current methodologies employed in the creation of structured nonwoven substrates, including thermal, hydroentanglement, ultrasonic, and mechanical techniques. These processes play a critical role in optimizing fluid management, improving dermal interaction, and enhancing air permeability in hygiene applications.

A central focus is placed on recent advancements in integrated roller-based systems, such as the VoluMAX� technology, which enable simultaneous embossing and aperturing at high line speeds. The study discusses key engineering challenges in process design, including thermal control, web tension management, pattern precision, and the effects of anisotropy on final material properties.

Emerging trends are also examined, such as the drive toward basis weight reduction without compromising performance, multilayer lamination strategies, and the development of advanced trial configurations
