The solutions to the problems of staining and yellowing Spandex
AddTime:2016-01-06
We spent years developing a nonstaining nonyellowing Spandex product and we have the solutions to these problems.

Not all countries making Spandex is currently using the technology I developed to reduce yellowing and degradation of the Spandex.

The key is the choice of antioxidant that will not stain or discolor under all testing protocols used for Spandex including what is called gas yellowing or gas fading or gas yellowing. This yellowing is due to the presence of oxides of nitrogen that are part of auto exhaust and gas fired furnaces and coal burning. Any oxides of nitrogen will start yellowing most plastics especially white pigmented and natural.

The choice of antioxidant and its solvent solubility in the process solvent used in the Spandex process is key.
