fabric stiffness tester

4. INTRODUCTION
Stiffness :
 Stiffness is a special property of fabric.
 It is the tendency of fabric to keep standing without any
support.
 Stiffness is one of the most widely used parameters to judge
bending rigidity and fabric handling.
 Fabric stiffness and handling is an important factor for the
end users.
 The degree of fabric stiffness is related to its properties such
as fiber material, yarn and fabric structure.

5. Stiffness tester
 Stiffness Tester is used to determine the stiffness of fabrics.
 Use For the quick and accurate measurement of fabric
stiffness

6. instrument used in the measurement of
stiffness
 The Shirley stiffness tester
 The drape meter
 The Heart loop test

7. The Shirley stiffness tester
A fabric testing instrument that is used for
determine the stiffness of fabrics.

8. Description of Shirley stiffness tester
The stiffness tester is consists of a platform, having a smooth
low friction, flat surface such as polished metal or plastic.
The platform is supported by two side pieces made of plastic.
Index lines are engraved on these side pieces, inclined at an
angle of 41.50 below the plane of the platform surface. At this
angle.
A mirror is attached to the instrument to enable the operator to
view both index lines from a convenient position.
A scale is supplied with the instrument to measure the bending
length and is graduated in cm.

11. Apparatus:
1. Stiffness Tester
2. Scissor
3. Scale
Sample:
Cotton woven fabric
Size: 6 X 1.
Atmosphere:
Temperature – 25C and relative humidity – 67%
Standard atmosphere: temperature – 20oC and relative humidity - 65%.

12. Procedure
 3 samples are cut in warp and 3 in weft directions.
 Sample dimensions are 6inx1in.
 One by one, these samples are put on the tester and a
scale is put on the fabric.
Then sample is moved with slab and measure the angle and
a mark is made in one side of the sample.
 Then 6 values of each sample is used in calculating their
mean value.

Data table

16. Result
The bending length of the fabric in
warp way is 2.66 .
The bending length of the fabric in
weft way is 2.51 .

17. Conclusion
 If the bending length of the fabric is more than fabric
stiffness is more and if less stiffness is less.
