  • Spandex is a elastomeric fiber in which the-fiber-forming substance is a long chain polymer consisting of at least 85% segmented polyurethane. In the polyurethanes there are the additional oxygen atoms in the main chains of the molecule. The effect of these oxygen atoms is to make the molecule somewhat more flexible. From a physical point of view, elasicity and recovery from stretch are the most important properties of polyurethane, so its use has now expanded into many kitting industry. In this paper, I wish to Test the effect of dyeing condition on the quality of polyurethane.
