How is the elasticity of RUBBRE ELASTIC YARN achieved?

1. Material composition
Rubber component:
Rubber is the key component to achieve elasticity in RUBBRE ELASTIC YARN. It can be natural rubber or synthetic rubber, such as polybutadiene rubber, polyisoprene rubber, etc.
The rubber molecular chain has flexible segments that can deform when subjected to force and return to its original shape after the external force is removed, thus giving the yarn elasticity.
Textile fibers:
RUBBRE ELASTIC YARN usually also contains textile fibers, such as polyester fibers, nylon fibers, etc. These fibers provide strength and wear resistance to the yarn, and also contribute to the overall performance of the yarn.
2. Manufacturing process
Crosslinking and vulcanization:
During the manufacturing process of RUBBRE ELASTIC YARN, the rubber molecular chains are connected together through crosslinking reactions (such as vulcanization process) to form a three-dimensional network structure. This crosslinking structure makes it difficult for the rubber molecular chains to slip and break when subjected to force, thereby maintaining the stability and elasticity of the yarn.
Composite technology:
RUBBRE ELASTIC YARN uses composite technology to intertwine and mix rubber yarn with other elastic fibers (such as polyether ester elastic fibers, composite elastic fibers, etc.). This composite structure can further enhance the elasticity of the yarn and improve its strength and wear resistance.
III. Elastic mechanism
Molecular chain deformation:
When RUBBRE ELASTIC YARN is subjected to external force, the rubber molecular chain will deform, that is, the chain segment will be elongated or curled. When the external force is removed, due to the combined effect of the flexible chain segment and the cross-linking point of the rubber molecular chain, the chain segment can return to its original state, thus giving the yarn elasticity.
Energy storage and release:
RUBBRE ELASTIC YARN will store energy during the deformation process. When the external force is removed, this energy will be released to push the chain segment back to its original state. This process of energy storage and release is one of the important mechanisms for the elasticity of rubber elastic yarn.
