Quick Summary

Gel spinning is a technique used in the production of man-made fibers, a variant of solution spinning. In this process, a polymer with extremely high molecular weight is dissolved in a low-concentration solvent, creating a very viscous solution. This solution is then spun into fibers, which are essentially gels of polymer and solvent. While still in the gel state, the fibers can be stretched to align the polymer molecules into an elongated state, resulting in ultrahigh-strength and high-stiffness polyethylene fibers. This method has been commercially utilized since the 1980s.1

Gel spinning is an old technique that has come into use commercially only since the 1980s. As originally applied, solutions of very high solid contents (20–80 percent) were used; such solutions were similar to semisolids. In the modern adaptation of this process, polymer…
