Electronic
Yarn Friction Tester. To determine the coefficient of
friction of yarns and assess the need for lubrication or the
effectiveness of lubricant already applied. Provided with
variable input tension electronically measured and displayed,
calculates the difference between input and output tension
measured by 2 electronic tension transducers over a standard
frictional surface of stainless steel or ceramic to calculate
the coefficient of friction.
Yarn
is transported through nip rollers driven by an electronic drive
variable from 50-300 metres/minute and air suction removes the
tested yarn to waste. Tests are set up and controlled from the
computer keyboard for any number of tests of any length of yarn
carried out automatically.
A
real time trace of friction variation is displayed on the
computer screen followed by test analysis data and printed
reports. Processor software and printer included.
Laboratory standard compressed air supply needed.
Electronic
Yarn Hairiness Tester. To determine the number of hairs or
fibres over a specific length, protruding from the yarns.
Provided
with variable input tension, measuring head infinitely
adjustable from 0-10mm, electronically measuring interruptions
to an LED beam set at a specific height protruding from the
surface of spun yarns or broken filaments on filament yarns.
Yarn is transported through nip rollers driven by an electronic
drive variable from 50-300 metres/minute and air suction removes
the tested yarn to waste. Tests are set up and controlled
from the computer keyboard for any number of tests of any length
of yarn carried out automatically. A real time trace of
hairiness variation is displayed on the computer screen followed
by test analysis data and printed reports. Processor,
software and printer included. Laboratory standard compressed
air supply required.
Also
available as a combined or dual purpose instrument with both
friction and hairiness measuring components, controls and
software for both tests. Use for separate tests, will not
combine both measurements during the same test.
