  • Tprinciple of wet spinning process-Part 8Affects solubility about supramolecular deconstruction
    Effects of supramolecular deconstruction1. Amorphous polymers are more solube than partly crystaline polymers. This is because the force between the former macromolecule is weak,and the latter due to the strong force between the molecules of the crystalline part,to make it completely dissolved,a hi
