With a raised global awareness of industrial environmental pollution, the polymer research is focusing on green biopolymers. The spinning gland of spiders and silk moths is the holy grail in green extrusion, as silk is spun at ambient conditions and is water based. This achieved by finely tuned spinning parameters in the silk gland, whereby the soluble silk solution is converted into a solid fibre. To date, no one has ever succeeded in spinning at these ambient conditions, used in the natural spinning system. In this project, one missing spinning parameter will be investigated,  namely small molecules, in the form of polyphenolic compounds, that are also extruded together with the silk.
