one. The distinction between The 2, just take core spun yarn and covered yarn for instance. Main spun yarn is spandex wrapped with staple fibre with spandex yarn since the core and non-elastic staple fibre outside, and the Main yarn is frequently not uncovered when stretched.
While some producers even now make the most of response spinning, Alternative soaked spinning, or soften extrusion to manufacture elastane products and solutions, solution dry spinning takes the lead, accounting for more than ninety five% of the whole world’s spandex output.
Pursuing this, the prepolymer undergoes a sequence extrusion reaction with diamine acid, leading to a very viscous substance. To manage its thickness, manufacturers introduce a solvent. They feed the thinned solution right into a fiber output mobile, that's a cylindrical system that includes a specialized spinneret.
