Abstract
The P. V. C fibers containing dinitronaphthaline (DNN) are manufactured by dry spinning of P. V. C solution in acetone and CS2, and the fibers are drawn up to 400% elongation at 100°C.
The stress-strain curves of PVC-DNN fibers thus obtained are measured by Instron tensile tester. From these results, it is found that the strength and elastic properties of P. V. C fibers containing 5-10% DNN are larger than those of pure P. V. C fibers but the elongation of P. V. C fibers containing 5-10% DNN are smaller than those of pure P. V. C fibers.
These properties of DNN contained in P. V. C fibers are maintained in the remarkably wide range of temperature, but at about 100°C, the deformation and shrinkage of P. V. C fibers are smallar than those of DNN containing fibers whose permanent deformations are however comparable with the P. V. C fibers.
