As discussed in the ResearchGate article “Ultrasonic Weldability of Thick and Heavier Nonwoven Fabrics,” nonwovens are popular in various applications due to their cost-effectiveness, high production efficiency, and customizable properties. While typically used for disposable products, innovations such as combining bicomponent fiber spinning with hydroentanglement have enabled nonwovens to be employed in more durable applications. Ultrasonic welding has emerged as a viable method for assembling these heavier and thicker nonwoven fabrics, particularly those made from polyester: polyamide bicomponent microfilaments.

The study examined 60 samples created using five different nonwoven fabrics with varying weights and 12 selected ultrasonic welding types. Despite the challenges posed by the thickness and fiber composition of these nonwovens, the study found that successful welded seams could be achieved, even with seam lines up to 1.6 mm thick. While some samples exhibited waviness, color changes, and deformations in the seam lines due to specific welding parameters, these factors did not significantly impact the overall seam strength.

Leveraging cutting-edge techniques like ultrasonic welding to enhance the durability and functionality of nonwoven fabrics. By understanding the weldability of different fabric types, we continue to innovate and deliver high-performance solutions to our clients across various industries.
