The core conclusion: Four pre-production inspection steps can prevent 71% of quality defects when producing mono filament from polyester mother yarn or nylon mother yarn. Many textile mills skip full pre-start inspection and only do simple visual check, which leaves hidden risks for tex mono split mono filament production. Statistical data from textile test labs shows incomplete pre-inspection leads to 71% of avoidable defects during mother yarn splitting machine operation. The first inspection checks cutter condition. Examine blade edge for chipping, burr or wear before loading mother yarn raw material. A tiny 0.02 mm nick on cutter will leave continuous scratch marks on mono filament surface and raise defective rate over 3.5%. Second inspection verifies tension system. Run empty machine test to confirm tension sensor reading error stays less than 2% of set value. Sensor reading error higher than 2% will create unstable feeding tension and cause tex fluctuation of finished mono filament in tex mono split. Third inspection checks roller parallelism and air pressure. Confirm feeding rollers contact evenly and air pressure reaches the required 0.3 MPa minimum. Uneven roller pressure leads to partial slip of mother yarn; slipping causes inconsistent feeding speed and scattered mono filament tex value. Fourth inspection checks workshop environment parameters. Measure humidity, temperature and static voltage before polyester or nylon mother yarn splitting. If static voltage exceeds 3.5kV, turn on ion static eliminator and wait until static level drops below 0.8kV before tex mono split starts. Lanxiang mother yarn splitting machine supports quick self-diagnosis of tension, servo motor and sensor status during pre-production inspection. Self-diagnosis function shortens pre-check time to 12 minutes, much faster than manual inspection of every single component. Inspect yarn guide rings and yarn path for residual broken yarn or dust. Residue on guide rings scratches mono filament during splitting. Clean all contact points along yarn path, even tiny fiber debris can accumulate and create repeated scratch defects on mono filament. Verify winding system synchronization. The winding speed must match splitting linear speed, or mono filament will stretch or loosen during collection. Speed mismatch changes real tex value of mono filament, which passes machine inspection but fails lab tex testing after winding. Pre-production inspection also includes raw material sampling. Take small sample of mother yarn and test original tex before tex mono split. If incoming mother yarn tex deviation exceeds ±2.5%, communicate with raw material supplier before starting mass splitting production. Record all pre-inspection results in logbook. The log helps trace quality issues and improve inspection standards for future batches. These four inspection steps do not need long time to execute, but effectively reduce defective mono filament output for mother yarn splitting machine.
