Advance Techo

ProcedureThe instrument is leveled with the help of the leveling screws and spirit level. The specimen is folded gently end to end with its edges in one line, with the help of the tweezers. The edges should not be gripped more than 5mm in the tweezers. The folded specimen is placed on the lower plate of the loading device and the load is applied gently.

Before loading, a metal foil with thickness not more than 0.02mm is placed between the limbs of the specimen. The load is then removed after 5 minutes.

Half the number of test specimens, both warp and weft should be folded face to face and the other half back to back.
Measurement Of Recovery AngleAfter the load is removed, the specimen is transferred to the clamp of the instrument. For this, one limb of the specimen is hold in the tweezers and the other limb is placed in the clamp. As the specimen recovers, the dial is rotated to keep the free edge of the specimen in line with the knife edge. At the end of the time period (5 min) allowed for recovery, the recovery angle in degree is read on the dial.

The above procedure is repeated for all the warp way and weft way specimens and the average recovery angle is calculated. The load, time of creasing and recovery time may be altered to suit different fabrics. The test should be include the following –
a.     The type of fabric tested.b.     Number of tests performed.c.      Load applied.d.     Time of creasing.e.     Time of recovery.f.       Mean crease recovery angle.g.     Warp way specimens.h.     Weft way specimens.
