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.
Why is spider silk so strong?
Spider threads contain many long molecules called proteins. These proteins are aligned along the thread and all work together to hold up the spider. In part, spider thread is strong because there are so many proteins all lined up together.
