Ultrasonic Non Woven Fabric Sewing, has become increasingly popular in a number of industries.
For example, businesses in the textile and personal products industries often manufacture products such as diapers, clothing, etc., that are ultrasonically welded.
Ultrasonic sewing tools operate under the principle of applying acoustic energy in the ultrasonic frequency range (i.e., at or above 20 kHz) to a horn. The horn vibrates in response to the applied acoustic energy to further produce an output acoustic energy. The output acoustic energy is applied to the materials (typically thermoplastics) being joined by positioning the horn in the vicinity of the parts. The vibrational energy travels through the parts, and at the interface between the parts, is converted to heat. The conversion is due to intermolecular friction that melts and fuses the parts together.
Ultrasonic sewing is also the method of choice for these materials, for example for parting fabrics so that there is no thickening of the material along the cut edges.
No consumables such as glue, staples or sewing thread are needed. The fabric remains intact, because no external thermal energy is directed into the fleece. Position, shape and displacement of the welding points can even support the desired properties of the composite.
Textiles is thus a field where ultrasonic technology can prove its uniqueness.

slit, trim, tack, emboss, or to cut and seal at the same time. The process used by every ultrasonic sewing machine is fast, simple and efficient. It can seal up to 80 meters per minute without the need for threads nor needles.
It is indeed a flexible technology. Due to the adaptability of its design, it is possible to mount the sewing machine on a workbench or to install it into semi or fully automated systems.
The general principle of ultrasonic welding can also be applied to nonwoven materials. The thermoplastic fibers are activated by mechanical vibrations thus melting and bonding in pre-defined patterns. A weld tool, referred to as Sonotrode, transmits the vibration into the nonwoven material. In industrial applications, ultrasonic frequencies between 20 and 35 kHz are common, with amplitudes (tool travel distances) of 10 µm to 50 µm. Processing of nonwoven materials is often performed in continuous processes at high web speed. By application of rotary tools, it is possible to achieve processing speeds of up to 800 meters/minute. A specifically engraved drum is used as welding, embossing, or cutting anvil. The contour of the anvil drum focuses the energy and precisely defines the weld spots required for the respective product.
