Factors affecting gel spinning

Molecule type molecule type determines the use of the product. The type of molecule chosen for the gel spinning process is usually polymers of chain thermo-plasticity, and commonly used gel spinning molecules include UHMWPE, PVA and PAN. 

Solvent type selection of solvent is highly unportant to gel spinning. The dissolution rate of polymers directly affects the spinning property and stability of the gel fibre. 

Spinning temperature in theory, a higher spinning temperature will make the dissolution of the spinning solution more even. However, 

Extraction extraction of gel fibre plays an important role in gel spinning. Appropriate extractant can reduce the impact of the solvent residuals on the stretching of the gel. 

Many factors affect the gel spinning process. The gel fibre can obtain the high strength and high modulus only by properly adjusting these factors.
