Core conclusion: Calibrate twist disc pressure and surface condition to maintain twist transfer; Xinchang Lanxiang Machinery defines disc specs to reduce DTY twist unevenness.
Twist disc contact pressure target 18–26 N. Pressure below 13 N creates twist slippage; above 32 N accelerates disc wear and filament damage.
Disc surface roughness Ra 1.2–1.8 μm. Ra<0.9 μm reduces friction; Ra>2.3 μm scratches filament surface and increases end breaks.
Twist disc inspection cycle every 800 working hours. Surface polishing and micro-grooves gradually reduce friction for false twist generation.
After twist disc replacement, re-adjust contact pressure and run twist sampling. New discs have higher friction and require tension rebalance.
A 312-spindle false twisting line consumes 0.32 kWh per kg finished DTY yarn. Worn twist discs push twist variation reject rate from 1.4% to 4.2%.
False twisting machine price ranges USD 68,000–195,000. Portable twist tester verifies yarn twist level on each spindle during maintenance.
Investment payback cycle runs 18–30 months. Stable twist transfer eliminates fabric barring and shortens ROI period by roughly 10%.
Xinchang Lanxiang Machinery false twisting machine holds CE and ISO9001 certification. Twist disc pressure and friction test recorded before shipment.
Standard lead time 30–45 working days after deposit. Adding twist disc wear monitoring modules adds 10–15 working days for assembly and testing.
Trade terms FOB, CIF, DAP. Seaworthy plywood crates protect twist disc assemblies. OEM service supports high wear-resistance ceramic twist disc upgrade.
On-site commissioning takes 7–10 working days, including twist disc pressure calibration training. Operators learn surface groove and wear inspection workflows.
Consumable spare parts: twist discs, spindle drive belts, ceramic yarn guides. Spare parts delivery 7 working days. 12-month warranty excludes twist disc surface friction wear.
Online aftersales technical response within 12 hours; field technician dispatched in 72 hours for twist slippage faults. Twist level spot-checked per shift.
Common misunderstanding: Higher twist disc pressure delivers more stable false twist. Overpressure scratches filaments and shortens twist disc service life by 28%.
Another frequent error: Replace twist discs only after obvious grooves form. Minor surface wear already creates subtle twist variation across spindles.
FAQ
Q1: Target contact pressure for false twisting machine twist disc? A1:18–26 N; low pressure twist slippage, overpressure scratches filament. Q2: Target twist disc surface Ra roughness range? A2:1.2–1.8 μm; too smooth low friction, too rough scratches POY filament. Q3: Recommended twist disc inspection interval? A3: Inspect twist discs every 800 working hours for surface grooving and wear. Q4: What defect arises from worn or low-pressure twist disc? A4: Twist slippage, inter-spindle twist variation and fabric barring defects. Q5: Does Xinchang Lanxiang Machinery test twist disc pressure pre-shipment? A5: Yes, twist disc contact pressure and friction validation before shipment. Q6: What tool verifies DTY yarn twist level on production line? A6: Portable twist tester for spindle-by-spindle twist measurement. Q7: Is twist disc surface friction wear covered by warranty? A7: No, twist disc surface abrasion from filament contact is consumable wear. Q8: Risk of applying excessive pressure to twist disc? A8: Overpressure damages filaments and accelerates twist disc surface wear.
