How is Elastane made?
Elastane is made through a process called solution dry spinning, which involves dissolving the fiber-forming substance in a solvent and then spinning it into a fiber. The solution is first created by mixing the raw materials, such as polyurethane, with a solvent, such as dimethylformamide. The solution is then pumped through a spinneret, which shapes the solution into a fiber. The fiber is then passed through a series of rollers and heaters, which remove the solvent and cause the fiber to solidify.
The resulting elastane fiber is then treated with various chemicals and finishes to give it the desired properties. For example, the fiber may be treated with a textile finish to improve its softness and durability. The fiber may also be dyed or printed to give it color and texture. Once the fiber is finished, it is cut to the desired length and packaged for use in textile manufacturing. The production of elastane is a complex process that requires careful control of temperature, pressure, and chemistry to produce a fiber with the desired properties.
