Why is the rope twisted together?
2022 09/28
Take nylon rope as an example. Nylon rope uses nylon as the main material. Nylon chemistry is called polyamide.Polyamide is a general term for polymers containing amide groups in the repeating units of the main chain of macromolecules. Polyamide can be obtained by ring-opening polymerization of internal acid amines, or can be obtained by polycondensation of diamines and dibasic acids. The molecular structure is It's not just a straight line, so the curve is the original state. I suddenly remembered that the high school chemistry teacher explained that the headphone cable would always twist together.
