E. STRETCH TEST
Wind the Control Lever until the needle aligns with 0 on the Length Ruler.
Loosen the Clamps at each end of the Fabric Bed.
Insert both ends of the swatch between the Jig openings, aligning the 10mm line marks.
Tighten the Clamps at each end to secure the swatch ends.
Turn on the Digital Force Gauge.
Determine Length constant:

1) Pull the fabric swatch until the force value is 0.01kgf.
2) Starting with the length reached at step 1, check the length and force of each 10mm increment.
3) Record 10 sections.(In the case of not being able to record 10 sections, record all the measurable sections.)
4) Use a value only when the force difference of each section is at least 0.02kgf.(If the force difference for each interval is less
than 0.02kgf, do not use that value.)
5) Finally, select and use values resulted in at least 3 sections and up to 5 sections.(We recommend that you fill out all five
sections as much as possible because the more measurements you have, the more accurate the data is.)
1) Check the value of the force when swatch is pulled to 1mm.
2) Starting with the length reached at step 1, check the length and force of each 1mm increments.
3) At this time, measure 3 to 5 sections.(We recommend that you fill out all five sections as much as possible because the more
measurements you have, the more accurate the data is)
We recommend you to fill out all five sections as possible because when you have more measurements, data is more accurate.
When the swatch is pulled by 1mm and the force is less than 0.01kgf
When the swatch is pulled by 1 mm and the force value is over 0.01kgf
The stretch test will allow you to measure the stretchability and threshold at which a fabric will no longer stretch.
To do this you will explore the relationship between length of stretch and force applied to the swatch, then
record and input your findings into the Emulator Mode of CLO.
The reading from the Length Ruler and Digital Force Gauge combined will be one set of measurements.
You will need a minimum of 3 sets and a maximum of 5 sets for each swatch.
When testing, you will need to determine, which unit of length will be your constant.
