Among the variables in the extrusion and the stretching process of Saran, the most important factor affecting the mechanical properties of a filament is the stretch ratio. The second, is the temperature of the cooling bath, the third is the stretching temperature and the least important factor is the die temperature. In order to investigate the changes in fine structure of filaments, 40 samples were made under various conditions of the above-mentioned four factors. The following three typical filaments were included in these 40 samples.(1) An isotropic amorphous model filament; this is a typical unoriented filament having no fibrous properties.(2) A standard model filament; this is a commercial Saran filament and is the standard used for comparing the behavior of other samples in stretching and heat treating.(3) An anisotropic crystalline model filament; this is a highly oriented filament prepared under a most severe condition of stretching. It fibrillates easily and its tensile strength is 3-4 g/d; however, its tensile elongation is below 10%.
