As detailed by Sollex in their article “Industrial Cutting Methods for Nonwoven Fabrics,” cutting techniques are crucial in the production and processing of nonwoven materials. After production, nonwoven materials must be cut into desired widths and forms, a step that significantly impacts the quality and usability of the final product.
Rotary Cutting Industrial rotary cutting machines, often automated, are ideal for cutting thick or multiple layers of nonwoven fabrics simultaneously. These machines use a rotating circular knife to achieve the desired width. The key to effective rotary cutting is maintaining an extra-long and sharp grind on the circular blade. Utilizing these techniques to ensure precise cuts for various nonwoven applications.
Razor Slitting For thin nonwovens wrapped on spools, razor slitting is an effective method. This process involves a rewinder machine where the material is tensioned and cut by industrial blades. Enhanced blade coatings reduce heat build-up and improve performance during cutting, making this method suitable for high-speed operations.
Plotter Cutting Plotter cutting, or digital cutting, employs CNC technology to cut nonwoven materials placed on a vacuum table. An oscillating knife cuts complex designs and patterns with high precision and accuracy. This method is ideal for intricate shapes, which are often required in specialized applications.
Die-Cutting Die-cutting uses specially designed dies to punch nonwovens into specific shapes. The material is placed between the die and a cutting press, which applies pressure to form the desired shape. This method can also involve serrated knives for straight cuts, providing flexibility for various design needs.
Ultrasonic Cutting Ultrasonic cutting applies high-frequency vibrations to a cutting knife, making it a fast and accurate method for complex shapes and patterns. The speed of the ultrasonic knife far exceeds that of traditional oscillating knives, offering superior precision.
Laser Cutting Laser cutting uses high-powered lasers to cut through nonwoven materials, commonly used in the medical and hygiene product manufacturing, such as surgical masks and gowns. This method offers clean cuts and is highly effective for detailed and delicate materials.
Each cutting method has its advantages and is selected based on the specific requirements of the application, such as accuracy, speed, and material properties. Often, manufacturers use a combination of these methods to achieve optimal results.
