Subject content Basic demands on polymers for fibers manufacture. Rheological properties of liquid polymers and fiber spinnability. Mechanism of fibre forming and technological prerequisites - chemical spinning. Final fiber structure formation and fiber properties. Technological procedures of chemical spinning: melt spinning, dry and wet spinning; Making processes of main man-made fibres. Special technology of spinning inorganic fibres. Target modification of fiber properties in the production process: by adding co-monomers, additives, by incorporation of microcapsules (nanotechnology), by varying process parameters, at the level of micro and macro morphology, by crimping, by applying spin-finishes. Processes and technology of microfibre making.
Aim of course Knowledge of the mechanisms of man-made fiber formation; observing the dependence between process parameters of chemical spinning and structure and properties of produced fibres; significance of high technology in the development of new high-performance fibers and materials. Basic qualification for the chemical spinning process control.
