We tried the separation of EI and GIp values, necessarily followed by twisting from the sample of 2-folded yarn.
The G value accompanying the untwisting of a yarn set at 190°C, temperature is higher as compared to a yarn set in aqueous phenol solution (concentration; 2%), until the number of untwisting equall to that of previously twisted yarn, and when the untwisting is over, they become equal in value.
The higher the temperature of the phenol solution, both values tend to approach the same over all ranges of untwisting.
Therefore, from the stand-point of G value, there is no fundamental difference between the heat and swelling sets.
The behavior of moment accompanied by the untwisting of a single twisted filament may be explained by the assumption that a single filament consists of multifibril.
