中文简体The elasticity of twisted nylon yarn is one of its distinctive features. This performance comes from its unique molecular structure and preparation process.
Molecular structure: The molecular structure of nylon fiber gives twisted nylon yarn superior elasticity. Nylon is a polymer whose molecular chain arrangement and intermolecular forces allow the fiber to deform after being stressed and quickly return to its original shape when the external force is removed. This ordered molecular structure provides elastic support for twisted nylon yarn.
Twisting process: The key process for preparing twisted nylon yarn is twisting. By combining multiple fibers together in a rotating and twisting manner, an intertwined structure is created. This structure allows the fiber to stretch when external tension is applied and to rebound quickly when the tension is removed. The twisting process gives twisted nylon yarn its unique elastic properties.
Elastic modulus: Twisted nylon yarn has a moderate elastic modulus, which is the extent to which elastic deformation occurs when force is applied. This allows the fiber to maintain its shape when subjected to strain while also being able to quickly return to its original state when the strain is removed. This balanced elastic modulus is one of the reasons for the success of twisted nylon yarn in a variety of applications.
High strain capacity: twisted nylon yarn exhibits good strain capacity when subjected to stress. Even when subjected to large amounts of tension, the fibers are able to stretch without permanent deformation. This high strain capacity makes twisted nylon yarn excellent in applications that require frequent stress and deformation, such as elastic ropes, stretch fabrics, etc.
Temperature effects: Unlike some other fibers, twisted nylon yarn remains elastic at lower temperatures. This makes it more widely used in cold environments and less susceptible to temperature restrictions.
