摘要

Extrusion spun spandex is coming of age. With the improvement in polymers and manufacturing equipment, the use of extrusion spun spandex continues to grow. Given its environmentally friendly process and the variety of possible unique fiber attributes, extrusion spun spandex can bring about a new dimension to the world of stretch fabrics. Today, the production of the vast majority of spandex fibers is accomplished by two different solution spinning processes. These spinning processes are known as either a dry spun or a wet spun process. In the dry spinning process, the polymer is dissolved in a solvent, and then the heat- ed polymer solution is extruded into a filament as it passes through a column of hot circulating air.
