From Core to Spun: Why Cellulose Film is the Performance Standard for Spandex Winding
Thermal Stability in High-Speed Winding In spandex production, winding is a critical phase involving ultra-high speeds and extreme tension. During dry spinning, filaments emerge from high-temperature chimneys—often exceeding 200°C—and retain significant residual heat upon reaching the winder. Standard plastic films often soften or undergo micro-melting under these conditions, causing the…
