WebThe paired spinnerets have one to three segments. They are highly manoeuvrable for silk spinning and may be quite short or relatively long (as long as the abdomen in some mygalomorph spiders). The end segment of each spinneret has many spigots - hollow, hair-like silk outlets connected to particular paired silk glands within the abdomen. A spinneret is a device used to extrude a polymer solution or polymer melt to form fibers. Streams of viscous polymer exit via the spinneret into air or liquid leading to a phase inversion which allows the polymer to solidify. The individual polymer chains tend to align in the fiber because of viscous flow. This airstream liquid-to-fiber formation process is similar to the production process for cotton …
