But it can also be done differently. You can 're-programme' polyester into its new shape. You have to heat the rope for a short time, so that the polyester is 'programmed' into its new shape. This can be done by wrapping the rope around a large metal disc. I use soup cans for this, which have been made to measure. Cut off the sharp edges to be safe.
After the rope has been taken out of the ropewalk, a knot is tied at the ends and when the rope has stopped curling. It is wrapped around the tin. The beginning and end are fastened with a small clip . Watch out for kinks, as they can cause permanent deformation of the rope during the heating process. The place of the clamp also remains visible after the treatment. Place the beginning and the end of the rope there, which can be cut off.

Then the tin with the rope is placed in an oven pre-heated to 1750 for 5 minutes (NB. No hotter than 190 0and no longer than 5½ minutes. If you heat it too long or too hot it will melt and your rope will fail) . Take the tin out of the oven (with an oven glove) and remove the rope. It keeps its shape, does not fray, and the tension that was on the rope after twisting is also gone.

When you now look to the rope the unravelling is gone.

Edit 2: If you interrested in the codes that are mentioned on the different brands of yarn you can look here
https://en.m.wikipedia.org/wiki/Units_of_textile_measurement sometimes a shop where you can buy will give you the thickness of the yarn in mm. but most of the time you have to measure by your self.
