Strain Dependence of Stress Relaxation in Nylon 6

Nylon 6의 곤장대변화영역에 있어 응력완화거동의 실험적 고찰

Stress relaxation measurements under the various strains ranging from 5% to 20% have been carried out for Nylon 6 filaments at various temperatures of 18$^{\circ}C$ to 160$^{\circ}C$. The results are as follows. 1) Strain dependence upon stress relaxation decreases as the temperature increases. 2) Temperature dependence upon relative relation is found to be great and the relative relaxation increases as the temperature increases. 3) Degree of strain dependence can be modified by changing the relation and the temperatures.
