What is Spandex and How is it Made?
Spandex, also known as elastane or Lycra, is a type of synthetic fiber that is known for its exceptional elasticity and flexibility. It is made from a polyurethane polymer that is produced through a chemical reaction between polyol and diisocyanate. The manufacturing process involves several steps, including the synthesis of the polymer, extrusion, and texturizing. The resulting fiber is then treated with various chemicals and processes to enhance its properties and performance.
The production of spandex involves a complex series of chemical reactions and physical transformations. The polyurethane polymer is first synthesized through a reaction between polyol and diisocyanate, resulting in a prepolymer. This prepolymer is then reacted with a chain extender to form a high-molecular-weight polymer. The polymer is then extruded through a spinneret to form a fiber, which is then texturized to create a crimped texture. The fiber is then treated with various chemicals and processes, such as drawing and annealing, to enhance its elasticity and durability.
