Draft point drift of PET fiber
문제 현상
During PET fiber drawing, the draft point position is unstable and moves back and forth, causing fiber fineness fluctuation.
원인 분석
Drawing temperature is unstable; drawing roller speed fluctuates; fiber preheating is uneven; undrawn yarn quality fluctuates.
해결 방법
Stabilize drawing temperature and speed; ensure uniform fiber preheating (hot plate/hot roller ±1°C); control undrawn yarn quality consistency.
핵심 요약
PET fiber draft point stability determines fiber fineness uniformity.
