Why does spiral movement occurs for hollow fibers spinning machine??
When pressure and flow rate is adjusted, the flow of viscous polymer flows in a spiral movement into the water bath. Why is that so? The viscosity of the dope is rather low at around 1,100MPa.S, flow rate of bore solution is at its lowest..
The polymer is PES..
its a matter of positive and negative charges im not sure which is positive or negative as you have not mentioned what the polymer is but the differance in charges between the polymer and the water is different in different areas as whter has a fixed charge but this is balanced between the entire amount of water
