For measuring crimp rigidity, a skein of known number of strands is prepared from the package of yarn under test. This skein is then immersed in water filled in glass jar with a load of 0.1 g/denier/strand suspended on it. The rubber scale stretched so that the zero mark on it is at the level of the bottom of the skein. The load is then reduced to 0.002 g/denier/strand by removing the major load and the reading on the sale observed. This reading gives the value of crimp rigidity.
We provide the Window based software which give the different measurement parameter and the graph between load vs elongation. The report can be printout by using proper printer.
The load applied on the test specimen is determined by load cell and is indicate on a digital display.
