CREASE RECOVERY TESTER - Crease Recovery Tester determines the property of textiles to recover from creases by measurement of the recovery angle.
With loading weight and clamp.
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.
The VGOTECH 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
