1. Introduction
2. Principle of Gel Spinning
Gel spinning, also known as dry-wet spinning, is used to obtain high strength or other special properties in the fibers. The polymer is in a “gel” state, only partially liquid, which keeps the polymer chains somewhat bound together.Gel spinning can promote the polymer of fibre’s molecular weight, degree of orientation, crystallinity and fibre density effectively, and that contributes to increasing the fibre’s strength and modules.
