Groz-Beckert, world’s leading provider of industrial machine needles, has launched four animation films on fibre preparation, needling of nonwoven fabrics and structuring to deliver a better and perceptible understanding of mechanical bonding of nonwoven fabric. The movement of felting needles can hardly be perceived at speeds of up to 3,000 strokes per minute.

The animation “From Fiber to Nonwoven” analyses the movement of the needle and provide a detailed and time-delayed illustration of the overall process of nonwoven fabric manufacturing. The other animations, “Focus on Felting Needles”, “Focus on Fork Needles” and “Focus on Crown Needles” demonstrate the action of the felting needle in flat needling and the action of the fork and crown needles in structuring.
The animated images of the behaviour of fibres when the needle plunges into the product groove explicitly illustrates the change, delivering an advantage over statistical representations. The viewer can learn and understand the formation of fibres bond and loops. It also helps in better understanding of nonwoven products mechanically bond during needling.
In addition to the textile-technical visualization, the animations also offer an entirely new perspective on depiction of targeted nonwoven fabric characteristics based on needle selection. Felting needles helps to achieve a flat and uniform surface, while fork needles produce a grainy, and crown needles a velvet-like surface.
