An Overview
It is amazing to see what ultrasonic energy can achieve in joining,
cutting, patterning, and quilting on synthetic fabrics. These and
more operations are done without the use of thread or adhesives and
at speeds much greater than can be reached with sewing machines -
as much as four times the speed!
How does it work? As the fabric passes under the machine's horn,
ultrasonic vibration causes the materials to heat up and fuse
together. Without any additional glue or heat, the seam is
finished. When used with cutting edge tooling, the vibration cuts
through the fabric and seals the edges of the cut to eliminate any
fraying at the edges.
Sewing machine operators quickly adjust to this threadless sewing
technique. Modular systems are available for integration into
automated textile manufacturing equipment and web handling
equipment.
Plunge welding or cutting is accomplished by placing the material
over a fixed anvil and having the horn or tool descend to the
fabric. This approach is used to punch holes, such as buttonholes,
to cut fabric strips to preset lengths, or to join pieces together.
Principles of Operation
Every ultrasonic unit contains the following five elements:
1. A POWER SUPPLY which takes line power at 50 or 60 cycles and changes it to high
ultrasonic frequency at 20,000 cycles per second or even higher.
2. A CONVERTER which contains piezoelectric crystals which change the incoming
high frequency electrical signal to mechanical vibration.
3. A BOOSTER which transmits the vibration energy and serves to increase its
amplitude in much the same way as volume control on a radio.
4. A HORN which delivers the vibration energy to the plastic film or fabric
to be worked on.
5. AN ANVIL or backup part which supports the work piece and, in the case of
textiles, takes the form of a pattern wheel or non-rotating cutter
wheel depending on the application.
The ultrasonic vibration is transmitted from the horn to the
material. developing frictional heat where they touch. This
momentary heat fuses the edges of the fabric. If double plies are
present, the plies join together. Where a cutting edge is used on
the anvil, the fabric is cut through and the edges sealed at the
same time.
Materials
Materials may be 100 % synthetic or blends with up to 40 % natural
fibers. Nonwovens, woven, stretch woven or knit materials can be
bonded and cut or slit. Acrylics, acetates, polyester, nylon,
polyethylene, polypropylene, spandex and PVC are all suitable for
bonding or cutting. In general, the higher the synthetic content,
the easier it is to cut and seal with ultrasonic energy.
Some fabrics may be directional; that is, th
e fibers in one direction have a different composition than the
fibers in the other direction. This may lead to different results
depending on the direction of the cut and seal.
