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.

Stiffness tester

Stiffness Tester is used to determine the stiffness of fabrics.

Use For the quick and accurate measurement of fabric

stiffness

instrument used in the measurement of

stiffness

The Shirley stiffness tester

The drape meter

The Heart loop test

The Shirley stiffness tester

A fabric testing instrument that is used for

determine the stiffness of fabrics.

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.

Machine Specifications

M/c Name :The Shirley fabric stiffness tester

Model : MAG-C1601

Origin : Made in India

Angle of inclination of intersecting : 41.5

Template size : 200*25 mm

Scale size : 250mm

thickness- 3mm

Applied Standard :ASTM 3188

Physical dimension : size -250m , weight 2.5kg

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%.

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

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 .

Conclusion

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