|
|
During the test, a fabric sample is extracted through a specially
designed nozzle so that a force-displacement curve is generated,
containing information regarding the fabric hand. This curve is then
digitized through a data acquisition system and fed into a computer
for analysis. |

System Software |
|
 |
|
PhabrOmeter®
system software package is based on the pattern recognition
technique and it analyzes the curve and selects the relevant
features that define fabric hand. A series of standard test methods
have been used to identify the physical meaning and calibrate these
features. The final evaluation results, including a weighted
Euclidian distance, calculated in relation to the user defined
preferred fabric sample, as the total handle value, and those
features representing stiffness, smoothness, softness, etc. are
provided by the software. A standard report is generated for user to
print out the results of the evaluation process. |

PhabrOmeter® system provides fast and reliable measurements for
fabric, including:
- Drape coefficient;
- Wrinkle recovery rate;
- Stretch index;
- Extraction curve;
-
Numerical characteristics from the curve;
- 8 fabric hand attributes
from the data;
- A relative fabric hand value;
- A unique fingerprint for each tested fabric;
All of the fabric data will be save in a database for future use.

The Innovation |
|
|
The PhabrOmeter®
system,
a
fabric quality evaluation system，has
been developed by Nu Cybertek
in California, USA.
It
measures the “feels and looks”, or so called “sensory perceptions”, of such
sheet type fibrous products as paper, woven and knitted fabrics, non-woven,
leathers and others in contact with human skin.
Sensory perception has long been considered as one of the most
important quality attributes and yet difficult to test using instrument.
PhabrOmeter® system successfully solves the problem of fabric hand
evaluation. It not only provides a critical quality assurance method for
textile industry, it also offers solutions to other consumer product
industries, where product quality relies on sensory evaluation. Further it
may shed light on our understanding of relationship between physical
stimuli and physiological, psychological and social response.

PhabrOmeter®
Technologies |
|
|
PhabrOmeter system consists of an instrument and a sophisticated software
package. The system deploys the pattern recognition theory, by extracting
the quality characteristics of the product and connecting them to the human
sense, so as to provide fast and reliable quality
evaluation
results. It fills a very
important blank.
PhabrOmeter® system has made available a powerful tool for new and high-end
product development for manufacturers; for quality evaluation and pricing
policy in trading, and more interestingly, it provides currently absent but
critically desired tactile sensory information to facilitate online
shopping. PhabrOmeter® system can be used in such a wide range of
industries as the textile and clothing, health care, chemical, cosmetics
and automobiles.

A Proving Initial Success
|
|
At
present the PhabrOmeter®
system has gone far beyond the laboratory and is successfully
commercialized.
In the
past two years,
it has been adopted by industry giants and running in the US, UK, Germany,
Japan, Australia, and China, with highly positive feedbacks.
The Australian Wool Innovation has funded a project to use the PhabrOmeter®
system to authenticate fine wool products so as to set retail prices for
its new line of skin-contact knitwear.
A PhabrOmeter instrument is being calibrated to objectively measure wool
handle characteristics. Industry experts have provided a list of industry
descriptors which characterize wool handle for next-to-skin knitted fabrics
of lightweight knitted wool fabric. So far
“50 woollen fabrics measured for handle characteristics by the
PhabrOmeter
have been assessed by four fabric handle experts. The initial analysis
indicates that fabric softness is related to specific
PhabrOmeter
test results, which demonstrates the
PhabrOmeter’s
ability to actually measure handle.”
In a parallel development, after extensive use and examination, the
American Association of Textile Chemists and Colorists (AATCC) is currently
developing a standard test method for the PhabrOmeter®
system
via its Committee RA89.
