초록

Since a drawn fiber shrinks when treated with heat, fiber is treated with heat after drawing process to prevent heat shrinkage. The objective of this study is to investigate the effects of drawing conditions on the properties of PVC fiber, especially on heat shrinkage. Overfeed was applied to prevent heat shrinkage at the several positions during drawing process. Heat shrinkage increased with draw ratio, and decreased with overfeed ratio. Overfeed was most effective to reduce heat shrinkage when applied between the chamber 2 roller and the take-up roller. The chlorinated PVC(CPVC) content also affected the heat shrinkage, and heat shrinkage decreased with increasing CPVC ratio.
