The Elastic Principle Of Rubber Thread

Rubber thread, also known as elastic band thread, is a functional material with a core of natural or synthetic rubber and an outer layer of woven fiber.

Due to its excellent resilience and tensile strength, it is widely used in the elastic parts of clothing such as underwear, sports pants, and belts.

Its elasticity comes from the stretching and contracting properties of the internal rubber molecular chains. When subjected to external force, it can quickly extend and return to its original shape after release, and it does not easily loosen with long-term use.
