摘要
The present invention relates to a method for preparing spandex having improved unwinding properties and enhanced adhesive properties with a hot melt adhesive and, more specifically, to a method for preparing spandex by means of adding a polystyrene polymer to a polyurethane-urea solution which is a spinning solution. Therefore, when spandex is unwound, irregular ballooning, tension spikes and the like can be effectively improved and other physical properties are unaffected. And the adhesive properties with a hot melt adhesive are enhanced.
