Creases Recovery Tester
Product information
The ability of textiles to recover from creases is determined by
measurement of its crease recovery angle. In this test the test
specimen is first creased under a specified load for specified
period of time and it then transferred to the angle measuring
device where one of its ends is held in a spring loaded clamp while
the other end is allowed to fall freely under its own weight. This
clamped end is slowly rotated till the free end becomes vertical.
The angle of deflection of the clamped end from the horizontal is
read on a scale fixed to the ability of textiles to recover from
creases is determined by measurement of its crease the moving
clamp. This angle gives the measure of the crease recovery.
Crease Recovery Tester for fabrics consists of an arrangement to
crease a rectangular test specimen under a specified load for the
specified duration of time and an arrangement to measure the crease
recovery angle. Creasing is carried out by pressing the folded
tests specimen under a load of 1 kg between two flat surfaces. The
load is applied by mean of the dead weight of the upper flat
surface.
The arrangement for measurement of crease recovery angle has a
anodised aluminium scale calibrated in degrees mounted on a
vertical disc. The disc can turn about the axis of the scale and
has a spring loaded clamp located at 00 to hold one end of the test
specimen. The free end of the test specimen can be aligned against
a vertical edge fitted in front of the disc.
The test specimen is mounted on a brass strip for convenience in
use and is creased and held in the clamp while still fixed onto it.
