1, rubber band
The scientific name of rubber band is latex apron and latex tape. It is impregnated with latex. It has the characteristics of large elongation, good resilience, low price and convenient use. Its manufacturing process includes impregnation, vulcanization, demoulding, ring cutting (strip cutting) and other processes. Mainly used for binding articles.
2, elastic band
Elastic band: Also called elastic thread and elastic thread, the thin point can be used as the bottom line of clothing accessories, especially suitable for underwear, pants, baby clothes, sweaters, sportswear, rhyme clothes, wedding dresses, T-shirts, hats, busts, masks and other clothing products.

5. stretch cotton
Elastic cotton belongs to the technical field of non-woven fabrics. It is made of hollow curly fiber and low melting point fiber through a certain process to make elastic cotton with three-dimensional fiber distribution. Stretch cotton is to add very thin high-strength rubber bands when spinning. The composition of elastic cotton is generally 98% cotton +2% rubber band, which is mixed and woven.
Second, the introduction of flexibility
Also known as "elasticity". After an object is deformed by an external force, if the external force is removed, the force that can restore the object to its original shape is called "elasticity". Its direction is opposite to the direction of the external force that causes the object to deform.
Due to the diversity of object deformation, there are many forms of elastic force. For example, if a heavy object is placed on a plastic board, the bent plastic will return to its original state and produce upward elasticity, which is its supporting force for the heavy object.
