SCT stands for “Shape Control Twist”. SCT is a special yarn texturing process developed by Toung Loong that can maintain the cross-section shape of textured yarns, especially performing well on hollow cross-section fibers. During texturing process, it’s known that the shape of fiber is hard to maintain. However, the heat preservation (clo) value relates to the shape of hollow cross-section fiber directly. Toung Loong Textile MFG. develops this unique SCT process to maintain the shape of functional fibers during yarn texturing process. If maximizing functional performance of premium textured yarn is the goal of new developments, Toung Loong SCT is a great solution that a premium line must know.
