Microinterferometry of poly-p-phenyleneterephthalamide fibres dried at various temperatures

Conclusions

Poly-p-phenyleneterephthalamide fibres which have been subjected to drying at various temperatures have been studied by use of the “Biolar” polarizing interference microscope.

A significant change in the n(r) curves on change in temperature has been detected. Temperature elevation essentially does not show up in the axial orientation of the polymer macromolecules; however, the transverse orientation of the structural elements changes considerably.
