Optirate SAS - Smoothness Analysis System
|
Bringing objective measurement to subjective smoothness
testing
For objective measurement of smoothness and creases, the Opti-Rate
SAS has been developed with Cotton Inc. and Texas Tech. University
International Textile Center - and gives correlation to results
obtained by independent technicians working in accordance
to AATCC 124 and 143 Test Methods.
The Opti-Rate SAS produces rapid and accurate objective smoothness
grading measurements similar to those from a standard observer.
Using the latest 3D Image Processing Technology, utilising
a ‘Laser Smart’ Camera system and accurate positional control
of the specimen.

For other industries such as the development
of chemicals for fabric treatment the Opti-Rate SAS machine
can give information related to the number and type of creases
on the fabric, these include;
Number of long wrinkles, average profile height, short smooth
profiles, short sharp profiles, tall smooth profiles, all sharp
profiles, etc…. |
Standard AATCC & SAS Ratings
54 Samples
Standard grades, generated from AATCC Test Method 124 - Smoothness
Appearance (SA) after Home Laundering, are the average of three
specimens from three observers for each sample. After AATCC grading,
the same specimens were scanned on the Roaches Inc. Smoothness Appearance
System from which SAS SA Grades were produced. Visual grades were
performed by Cotton Incorporated personnel. SAS scans were made
at Cotton Incorporated, transmitted to the International Textile
Center where the latest grading prediction software was used to
produce the SAS SA grades.
