| Abstract: | An unusual observation has been made during stress relaxation experiments on as-drawn polypropylene
multifilament yarn which had not been subjected to any conditioning treatment. At 0.5% prestrain and at
temperatures of 60°C and above, the stress after an initial decrease registers an increase. This inverse
relaxation is not seen for a prestrain of 2% nor for annealed samples. On the basis of the results presented, the occurrence of the inverse relaxation has been attributed to the generation of shrinkage stress, which is a manifestation of structural relaxation during the test and is controlled by the cY-relaxation. |
