High breakage rate in PET fiber spinning
문제 현상
Frequent breakage during PET melt spinning, poor production continuity, uneven fiber quality.
원인 분석
Gel particles or impurities in the melt, improper spinning temperature, filter screen clogging, unstable cooling conditions.
해결 방법
Improve filtration accuracy (20-40μm filter screens), optimize spinning temperature 280-295°C, control melt residence time <15min, stabilize side-blowing air.
핵심 요약
PET spinning breakage is a comprehensive reflection of raw material purity, temperature, and filtration.
