Abstract

The density of Saran filament is measured by the density gradient tube method and the crystallinity is then calculated from the density. The crystallinity of Saran is calculated on the following two assumptions;(1) The crystalline part of Saran filament is pure polyvinylidene chloride.(2) Component of the filament has additive properties. The crystallinity of the standard filament is about 27%. The crystallinity of a filament tends to increase with the increase in stretching ratio, but is almost constant through the wide range of its stretching temperature. However, the crystallinity of a filament increases somewhat by heat treatment and the crystallinity of the anisotropic crystalline filament is about 35%. The crystallinity of a filament that is heat-treated under tension is greater than the crystallinity of a filament that is heat-treated without tension.
