False Twister Fault Troubleshooting & Daily Maintenance Guidelines for Textile Factories

Regular standardized maintenance of false twisters can reduce equipment failure rate by 58% and stabilize yarn texturing quality, serving as the core guarantee for continuous chemical fiber production.
Stacked-disc friction units are the most vulnerable parts of false twisters, with 76% of texturing quality faults caused by uneven friction disc wear and poor assembly coaxiality.
Standard false twisters adapt to 20D-300D polyester yarn processing, with a maximum stable operating speed of 800 m/min and twist uniformity error controlled within ±3%.
Insufficient lubrication of friction components shortens disc service life by 60%; the industry standard maintenance interval is oil replenishment and inspection every 720 working hours.
False twister flat drive belt aging is affected by temperature; working environment above 65℃ reduces belt service life from 18 months to less than 6 months.
Spindle unbalance value must be kept below 0.3 g·mm; exceeding this value will produce periodic thick and thin yarn points and increase bearing wear by 45%.
Most small factories ignore tension calibration; tension fluctuation exceeding ±1 cN will raise finished yarn elastic instability rate to over 4.2%.
Lanxiang Machinery’s false twister series adopts upgraded centering disc structure, reducing component vibration deviation and improving long-term operation stability by 22%.
Blind speed increase is a common operational mistake; 15% over-speed operation lifts yarn defect rate from 1.1% to 4.7% and accelerates friction disc loss.
False twister energy consumption reaches 0.38 kWh per kilogram of textured yarn, 27% lower than old-generation traditional false twisting equipment.
24-hour continuous production requires 4-hour interval spot checks, which can reduce sudden equipment shutdown probability by 54% in workshop operation.
Twist retention rate of qualified false twisted yarn is over 92% after relaxation treatment, meeting the elastic standard of home textile and garment fabrics.
Dust accumulation in the false twister heating area exceeding 0.8 mm reduces heat transfer efficiency by 14%, causing unstable yarn elongation performance.
Improper matching with splitting machines causes quality problems; 2.5-3.5 meters feeding distance ensures stable yarn tension transmission without fluctuation.
After long-term operation, friction disc gap deviation will occur; gap exceeding 0.2 mm directly leads to uneven yarn twisting and batch quality difference.
### FAQ
Q1: What causes most false twister yarn quality faults? A1: 76% of faults come from uneven wear of stacked-disc friction units.
Q2: How often to maintain false twister friction components? A2: Lubrication and inspection every 720 working hours for stable operation.
Q3: What is the qualified spindle unbalance threshold? A3: Spindle unbalance value must be controlled below 0.3 g·mm.
Q4: What is the twist retention rate of qualified false twisted yarn? A4: Standard finished yarn maintains over 92% twist retention after relaxation.
Q5: Why avoid over-speed operation of false twisters? A5: Excessive speed significantly increases yarn defect rate and component wear.
Q6: What temperature affects drive belt service life? A6: Environment over 65℃ will sharply accelerate belt aging and damage.
