How Is Elastane Fabric Made?

Four different methods can be used to produce this elastic fabric: Reaction spinning, solution wet spinning, melt extrusion, and solution dry spinning. Most of these production processes have been discarded as inefficient or wasteful, and solution dry spinning is now used to produce approximately 95 percent of the world’s spandex supply.
The solution dry spinning process begins with the production of a prepolymer, which serves as the basis of elastane fabric. This step is accomplished by mixing macroglycol with a diisocyanate monomer within a special type of reaction vessel. When the right conditions are applied, these two chemicals interact with each other to form a prepolymer. The volume ratio between these two substances is critical, and in most cases, a glycol to diisocyanate ratio of 1:2 is used.
When the dry spinning method is used, this prepolymer is then reacted with diamine acid in a process known as chain extension reaction. Next, this solution is diluted with a solvent to make it thinner and easier to handle, and it is then placed inside a fiber production cell.
This cell spins to produce fibers and cure the elastane material. Within this cell, the solution is pushed through a spinneret, which is a device that looks like a showerhead with lots of tiny holes. These holes form the solution into fibers, and these fibers are then heated within a nitrogen and solvent gas solution, which causes a chemical reaction that forms the liquid polymer into solid strands.
The strands are then bundled together as they exit the cylindrical spinning cell with a compressed air device that twists them. These twisted fibers can be made in a variety of thickness options, and every elastane fiber in apparel or other applications is actually made from many tiny strands that have undergone this twisting process.
Next, magnesium stearate or another polymer is used to treat the elastane material as a finishing agent, which prevents the fibers from adhering to each other. Lastly, these fibers are transferred to a spool, and they are then ready to be dyed or woven into fibers.
