The crystal structures of nylon-6 and nylon-6/clay fibers were investigated on annealing and drawing. Annealing increased the γ-crystalline form of both fibers, as indicated by the DSC curves, and its effect was dominant in nylon-6/clay fiber. On dr

The thermomechanical behavior of several rigid-rod polymeric fibers has been investigated. Up to 300°C, all fibers exhibited the expected axial shrinkage on heating (CTE ≃ -6 x 10 -6 °C -1 ). However, a pronounced increase in thermal contraction

Monomethyl-pendant poly(p-phenylene benzobisimidazole) (MePBI) has been spun into fiber and compared with an analogous methyl-pendant poly(p-phenylene benzobisthiazole) (MePBZT). From FTIR and WAXD, the former system has been found to exhibit intermo
