The formula of spinning ratio is as follows:

Spinning Ratio = (π * Df) / (π * Di)

Where:

• π represents the mathematical constant pi, approximately equal to 3.14159.
• Df is the final diameter of the spun product.
• Di is the initial diameter of the starting material.

To calculate the spinning ratio, divide the final diameter (Df) by the initial diameter (Di). Using π in both the numerator and denominator cancels out, leaving a simple ratio of the diameters.

Now Calculate by using Bobin, Flyer diameter, and Bobbin RPM.
