Axial heat shrinkage of polyvinylchloride fiber drawn to various extent were measured at 30-130°C and the following results were obtained.
As the temperature is increased heat shrinkage will increase and the rate of shrinkage becomes higher near the second order transition temperature of polyvinylchloride.
In accordance with the increase of the extent of drawing, heat shrinkage increases, but in the drawing over 400% it decreases. There are interesting relations between the ratio of drawing and the under area of the curve of shrinkage.
