PLA Textile Fiber Application
Sorun Belirtisi
PLA fiber spinning has a high breakage rate, uneven strength and poor dyeing performance
Neden Analizi
PLA spinning is extremely sensitive to moisture content, and fine-denier fibers require the 30ppm level; melt temperature fluctuations cause dispersion in filament diameter and strength; dual-stage filtration reduces the breakage rate by 40%
Çözüm
①Deep drying to the 30ppm level before spinning; ②Precise melt temperature control; ③Dual-stage filtration (20μm+10μm); after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
PLA spinning pushes drying and filtration to the limit; 30ppm moisture and dual-stage filtration are the hard indicators of stable spinning; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
