Switzerland-based Uster Technologies Ltd., a manufacturer of instruments for quality measurement
and certification of textile materials, has introduced to the market the third-generation model of
its Uster® Quantum Clearer. Just like its predecessors, the Uster Quantum 3 clearer analyzes a
running yarn — carded, compact-spun, air-spliced or water-spliced — taking measurements in order to
propose the best clearing limits to achieve the spinner’s quality and productivity needs in the
wound yarn. However, Uster reports the Quantum 3 features new foreign-matter, capacitive and
optical sensors capable of seeing the full yarn body and that are more powerful than sensors on any
previous generation model. The foreign matter sensor features multiple light sources to increase
detection and separation of unwanted colored fibers from non-disturbing vegetable matter. A new
polypropylene clearing option also is available. The company reports the capacitive sensor
technology is proven on Uster machinery, but the optical sensor has been redesigned and improved.
A new central clearing unit features a bigger, faster memory than offered on earlier models;
and a 14-inch touch screen. The unit communicates with the latest-generation Uster Quantum Expert
system, which can compare clearing settings at any winder and provide synchronization across
similar yarn lots.
Uster also reports the new unit was designed to be highly durable and able to withstand harsh
mill environments. The clearer core now is better sealed to keep out dirt and dust. Reinforced
sensors now can withstand vibration better than before. New blowing arrangements and a wider
Foreign Fiber sensor reduce both yarn and air supply dirt build-up at the sensor.
“We are delighted to demonstrate Uster’s technological leadership with the launch of the
groundbreaking new generation of our Uster Quantum clearer,” said Dr. Geoffrey Scott, CEO, Uster
Technologies. “We are confident that this product, available with optical and capacitive sensors,
will set new accuracy standards in quality measurement within the industry.”
