Within the SPIC cluster a wide variety of melt spinning equipment is available both for R&D as for production purposes.
For R&D purposes various spinning and spin-draw-winding (SDW) machines and drawing equipment is offered. The spinning equipment varies in size from bench-scale monofilament apparatus to production-scale machines with spinning speeds up to 8.000 m/min and a mass output per spinning position up to 60 kg/hour.
Below you can find more details on the available equipment.
Spinning is the process whereby a material, usually a polymer, is shaped into a bundle of filaments, called a fiber. In order to shape a polymer into a fiber, the polymer must be brought into a processable liquid state. This can be done by melting the polymer (melt spinning), or by dissolving the polymer in a suitable solvent (solvent spinning). In the case of melt spinning, the liquid fiber-forming material is extruded through the small holes of a spinneret to produce a continuous filament fiber. The spun fibers solidify by cooling in contact with air after extrusion from the spinneret. In order to achieve the desired properties spun fiber is drawn and heat-treated. This can be done in a separate process, or directly in an integrated spin-draw-winding process.
