Sono-Tek Announces First Textile Coater Sale

MILTON, N.Y., April 10 /PRNewswire-FirstCall/ -- Sono-Tek Corporation
(OTC Bulletin Board: SOTK), the world leader in the development and
application of liquid ultrasonic atomization technology, announced the sale of
the first ultrasonic WideTrack Textile Coater for industrial use. The coater
is based on Sono-Tek's proven WideTrack platform, which has been successfully
used in many glass line coating applications over the past four years. The
unit was sold to a major textile company, and will replace a traditional
finishing line at the customer's facility, which applies several different
finishes to the fabric.
The current approach in the industry to textile finishing involves running
a fabric line through a bath of chemicals and water to impart a desired
property such as water repellency, stain repellency, antimicrobial action,
flame retarding properties, etc. After this bath, the excess liquid must be
removed from the fabric, typically by passing the fabric line through a
heating section to evaporate the moisture. Since most fabric finishing
treatments are only required on or near the surface of the material, the bath
method is wasteful of chemicals, water and energy.
Sono-Tek's new WideTrack Textile Coater provides a series of ultrasonic
nozzles in a unit positioned over the fabric line, plus a computerized control
system to determine the flow of liquid required depending on the speed of the
line and the performance requirements of the finishing coat, and an integrated
pumping system. Less of the finishing liquid can be used in achieving the
required performance, and a reduction in heat energy is also achieved. Textile
customers have tried to use traditional pressure nozzles in the past to
replace the bath method, but had problems with clogging in the small openings
required in these nozzles. In contrast, the ultrasonic nozzle has a large
opening for the liquid, which does not clog. Furthermore, the ultrasonic
vibration provides a self-cleaning mechanism for Sono-Tek's nozzles, which
provides additional insurance against clogging, in addition to using less
liquid than traditional pressure nozzles. This system can be configured in a
variety of widths, up to 120" or beyond, if needed. Multiple solutions can be
supported in a single frame as well.
Sono-Tek CEO Dr. Christopher L. Coccio, stated, "Sono-Tek's WideTrack
Textile Coater offers the textile industry a key advantage in competing with
offshore manufacturers by saving them energy and chemicals in the application
of performance finishes. There is an added environmental benefit in that less
chemical and water use means less clean up afterwards, and a smaller carbon
footprint. We are very excited about the potential applications for our
textile coater, as the industry becomes familiar with this game-changing
technology. We also see additional benefits in allowing a manufacturer to
apply two independent coatings, one to each side of a fabric simultaneously.
This approach opens the door to fabrics that may attract moisture from one
side, yet repel it on the other, resulting in a new type of performance
fabric."
