Abstract
Aromatic polysulphonamides fibre, as a high-performance polymer fibre, was prepared by dry-jet wet spinning. The morphology and properties of polysulphonamides fibre along spinning line during dry-jet wet spinning process were investigated. From the development of mechanical and thermal property, it is shown that the fibre showed an improved stress, modulus and density along spinning line and the remarkable improvement was observed only as the fibre was hot stretched above its glass transition temperature (Tg). The property development of the fibre on spinning line is coordinated with the morphology and structure. When the fibre was drawn at the temperature lower than Tg, only the amorphous orientation was observed whereas the crystalline structure was formed as the fibre drawing temperature higher than Tg. The further optimisation of dry-jet wet spinning technology of polysulphonamides fibre could be supported by our results.
