Filature à jet d'air
Filature au mouilléProcédé dans lequel une solution de substance fibrogène est extrudée dans un milieu liquide de coagulation où le polymère est régénéré, comme dans la fabrication de la viscose ou de la rayonne cuproammoniacale.
Masse molaireLa masse molaire est la masse d'une mole d'une substance (un corps simple, un composé chimique). Elle s'exprime en grammes par mole (g·mol−1 ou g/mol).

| Résumé : |
The presented results deal with scientific, experimental and technical aspects of an advanced air-gap spinning technology of PAN-fibers spun from high-viscous DMSO solutions. Beside procedural investigations related to variation of fiber forming conditions at the spinneret, in the coagulation bath and at stretching in gel as well as dried state, the influence of the given factors onto fiber properties are discussed in comparison to common wet spun fibers. As a result, fibers possessing higher tensile strength and modulus could be obtained from 3 commercial polyacrylonitrile (PAN) polymer grades. A significantly increased solid content is expected to reduce production costs decisively. |
