Crimp Rigidity Tester For Testing Lab Workshop.
Crimp Rigidity Tester - For Testing Lab
Crimp Rigidity of a textured yarn gives a measure of its ability
to recover from stretch. It is determined by measuring the percentage
reduction of length of a skein of yarn immersed in water when a minor
load replaces a major load.
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 a glass jar with a
load of 0.1 g/denier/strand suspended on it. The length of the skein is
measured on a scale. The load is then reduced to 0.002 g/denier/strand
by replacing the major load by the minor load and the reading on the
scale observed. Crimp rigidity is calculated from the readings obtained
under the major and minor loads.
