PP Fiber Nonwoven Application
ظاهرة المشكلة
【Problem Phenomenon】Nonwoven fibers require raw materials with fine denier, high strength and low cost
تحليل الأسباب
PP fiber (polypropylene fiber) is lightweight and chemical-resistant, and is widely used in nonwovens (masks, hygiene materials, geotextiles), ropes, and carpets; spunbond and meltblown are the mainstream processes; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
الحل
Select spinning-grade PP for nonwovens; use high-MFI material for meltblown; select the grade according to fineness and strength; 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 polypropylene fiber is the king of nonwovens and the main force of masks and hygiene materials; 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 problems in the future
