Polymeric materials were evaluated with regard to their spinnability and respective fibre diameters. A modified single spinning device was firstly used derive a novel generalised model, utilising process parameters (die diameter, throughput, stretching relevant take-up pressures) material properties (zero shear viscosity) predict the diameter of polymeric fibres on basis four different polymers...

The superior biocompatibility and biodegradability of polyhydroxyalkanoates (PHAs) compared to man-made biopolymers such as polylactic acid promise huge potential in biomedical applications, especially tissue engineering (TE). Textile fiber-based TE scaffolds offer unique opportunities imitate the anisotropic, hierarchical, or strain-stiffening properties native tissues. A combination PHAs’ enh...

This work reports the use of cross-linkers in bio-based blends from hydroxypropyl-modified lignin (TcC) and a polyamide (PA1010) for possible as carbon fibre precursors, which, while minimising their effects on melt processing into filaments, assist cross-linking components during subsequent thermal stabilisation stage. Cross-linkers included highly sterically hindered aliphatic hydrocarbon (Pe...

Transient heat transfer models of the single-wheel meltspinning process are developed and applied to quantify the effect of process variables including interface depressions on solidification, temperature evolution, thickness variations, and surface depressions in the cast product. Firstly, a transient one-dimensional heat-transfer model of the melt-spinning process called STRIP1D was developed...
