Additionally, they are easily dyed.
To begin the spandex fabric production process, a substance called macroglycol is mixed with a diisocyanate monomer under specific heat and pressure.
Some of these corporations, such as , have factories in dozens of different countries, but others may be localized to one country in particular.
Additionally, it's possible that , which are toxic chemicals commonly found in polyurethane, may also be present in spandex, but there is no clear indication that this is the case.
Along with spandex, rubber and anidex no longer produced in the United States are considered elastomeric fibers.
Manufacturing Process of Spandex: Spandex fibers are manufactured in four different ways- melt extrusion, reaction spinning, solution , and solution wet spinning.
This impact is not as pronounced as the negative impact of other types of synthetic fabrics, but it is certainly present, and at this point, no feasible solutions have been suggested to curb the environmental degradation caused by spandex fabric.
Instead, all of the constituent parts of this fiber are made in a laboratory setting, and they are then combined under specific stimuli to create spandex fabric.
