PP Fiber Spinning Temperature
ظاهرة المشكلة
[Problem Phenomenon] PP spinning has broken and fuzzy filaments; improper temperature and drawing
تحليل الأسباب
PP fiber spinning temperature 250-280°C; draw ratio and cooling determine strength; temperature fluctuation breaks filaments; spinning speed and cooling coordination; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
الحل
Stable spinning temperature 250-280°C; draw ratio according to strength; uniform cooling; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes to facilitate locating effective measures
الخلاصة الأساسية
PP spinning 250-280°C; drawing and cooling determine strength; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar future problems
