Frequent filament breakage is a troublesome issue on mother yarn splitting machine in high-speed tex mono split processing. It interrupts continuous production, reduces output and may leave defective segments in finished polyester and nylon mono filament products. Multiple factors in production flow can trigger yarn fracture.
Raw material defects rank high among common causes. Tiny weak spots, thick-thin segments or internal impurity points inside mother yarn will break easily under tension when passing through cutting zone. Pre-production sampling inspection helps screen out such problematic yarn batches.
Over-high feeding tension stretches fiber beyond bearing limit. When tension exceeds fiber breaking strength, mono filament snaps instantly. For high-speed production, tension parameter should be lowered moderately instead of keeping fixed value from low-speed trial run.
Blocked or scratched yarn guide rings cut moving yarn. Fiber rubs against micro grooves on ring inner wall, accumulating surface damage until breakage occurs. Cleaning and periodic replacement of guide rings can remove this hidden risk.
Vibration of cutter assembly creates unstable cutting force. If fixing bolts loosen gradually during long-time running, cutter shakes slightly, producing uneven cutting and breaking partial mono filament in tex mono split processing.
Static electricity gathering makes single filaments tangle and pull against each other. Cross-wound yarns generate extra pulling force and cause intermittent breakage, especially in dry winter workshop environment without static elimination equipment.
Improper winding speed matching also induces breakage. If winding speed lags behind splitting speed, yarn accumulates and gets pulled sharply at the cutting outlet. Synchronous speed calibration eliminates such mismatching.
Lanxiang mother yarn splitting machine has real-time breakage monitoring module. Once filament breakage happens, the system triggers prompt and slows down operation automatically, reducing waste of mother yarn raw materials.
Root cause checking after yarn breakage helps prevent repeated faults. Recording breakage time, raw material batch and equipment status builds reference for optimizing tex mono split process parameters.
Q1: What raw material defect leads to mono filament breakage? A1: Weak points, thickness variation and internal impurities inside original mother yarn. Q2: How does excessive tension cause filament breakage? A2: It stretches fiber beyond its breaking strength and snaps the split mono filament. Q3: What damage on yarn guide ring will scratch mono filament? A3: Micro grooves formed by long-term abrasion on the inner wall of guide rings. Q4: How does static electricity trigger intermittent yarn breakage? A4: Static causes filaments to tangle, creating extra pulling force and fracture. Q5: What function does Lanxiang breakage monitoring module have? A5: It gives alarm and decelerates equipment automatically once filament breakage occurs.
