How do you make spandex?
Spandex is a synthetic fiber. It is typically made through one of four processes including melt extrusion, reaction spinning, solution dry spinning, and solution wet spinn…ing. Most of the spandex produced is done so using the solution dry spinning method. In the dry spinning method, a macro glycol with a diisocyanate monomer to produce a prepolymer. The prepolymer is then reacted with an equal amount of diamine. The resulting solution is then cured into fibers and forced through a spinneret. Once the solution is passed through the spinneret, it forms strands of liquid polymer which is heated in the presence of nitrogen and a liquid solvent. This forms strands of solid fiber which are bundled together to a desired thickness. The strands are then treated with a finishing agent. For clothing, spandex is often mixed with either cotton or polyester. (MORE)

Can spandex be dissolved?
Can spandex be dissolved? Yes it can. N-Methyl-2-pyrrolidone (NMP) is one chemical that will dissolve spandex (am looking for others). Keep in mind that its incred…ibly rare to have a piece of fabric comprised of 100% spandex. Generally polyester is blended with spandex in 85:15 or 90:10 ratios to give a material stretchiness. But NMP will dissolve spandex fibers from a spandex spool, but will not touch the polyester fibers. (MORE)

What are the monomers in spandex?
Spandex polymers are composed of three different monomers. Dialcohol monomers make up the rubbery, soft part of the polymer while diamine and diisocyanate monomers make up the… rigid, hard part of the polymer. The three monomers of spandex therefore are dialcohol, diamine and diisocyanate. (MORE)

Is there latex in spandex?
No, there is not. However most people with latex allergies have other allergies as well, and can cross react. Spandex is a man made fiber, where as latex is a natural rubber s…ubstance. Latex is stronger and more elastic and of course since it is natural is easier to come by. I have heard some people with a latex allergy state they can only wear up to a certain percentage of spandex in their clothing. My theroy is better be safe than sorry (MORE)

Will spandex shrink?
No, Spandex doesn't shrink because of its elastomer properties. It has incredible shape memory, and only after a few years of wear will it begin to lose these properties. So…, if your going to have the clothing item for a few years, I would be more worried about it losing its shape memory and sagging instead of bouncing back to its original shape, than it shrinking. Hope this helps. (MORE)
