Core conclusion: Controlling primary heater tube cleanliness maintains consistent heating for POY; Xinchang Lanxiang Machinery sets cleaning protocols to reduce DTY dye shade variation.
Heater tube set temperature window 185–215°C. Temperature deviation across spindles limited ≤±2.5°C. Deviation over ±4°C creates shade variation of 3.9%.
Tube carbon deposit cleaning cycle every 1500 working hours. Thermal decomposition residue coats inner walls, lowering heat transfer coefficient by up to 22%.
After chemical cleaning, verify tube surface emissivity and rebalance zone temperatures. Clean tubes transfer heat faster and may require slight temperature reduction.
A 312-spindle false twisting line consumes 0.32 kWh per kg finished DTY yarn. Heater fouling pushes reject rate from 1.7% to 4.5%.
False twisting machine price ranges USD68,000–195,000. Multi-point temperature sensing module monitors individual heater zone temperatures.
Investment payback cycle runs from 18–30 months. Uniform heating reduces fabric shade rework and shortens ROI period by roughly 12%.
Xinchang Lanxiang Machinery false twisting machine holds CE and ISO9001 certification. Heater tube temperature balance test recorded before shipment.
Standard lead time 30–45 working days after deposit. Adding multi-point temperature monitoring modules adds 10–15 working days for assembly and testing.
Trade terms FOB, CIF, DAP. Seaworthy plywood crates protect spindle and heater assemblies. OEM service supports high-temperature alloy heater tube upgrade.
On-site commissioning takes 7–10 working days, including heater zone balancing and temperature tuning. Operators learn carbon deposit inspection and cleaning workflows.
Consumable spare parts: heater tubes, temperature sensors, ceramic yarn guides. Spare parts delivery 7 working days. 12-month warranty covers heater housing, not tube fouling.
Online aftersales technical response within 12 hours; field technician dispatched in 72 hours for heater temperature drift faults. Tube temperature logged per shift.
Common misunderstanding: Only heater setpoint determines yarn heat setting. Carbon fouling reduces heat transfer even if display temperature stays unchanged.
Another frequent error: Raise heater setpoint to compensate fouling. Higher setpoint accelerates polymer decomposition and speeds carbon layer buildup.
FAQ
Q1: Primary heater operating temperature window for false twisting? A1: 185–215°C; spindle temperature deviation limited ≤±2.5°C. Q2: Recommended heater tube carbon deposit cleaning interval? A2: Clean heater tubes every 1500 working hours to remove carbon residue. Q3: What happens when heater tube inner surface builds carbon fouling? A4: Heat transfer coefficient drops up to 22%, causing uneven DTY heat setting. Q4: Maximum allowed spindle-to-spindle heater temperature deviation? A4: ≤±2.5°C; deviation >±4°C creates fabric dye shade variation. Q5: Does Xinchang Lanxiang Machinery test heater temperature balance? A5: Yes, full heater zone temperature balance test completed pre-shipment. Q6: What function of multi-point temperature sensing module? A6: Monitors real-time temperature inside each individual heater tube zone. Q7: Is carbon fouling of heater tubes covered by machine warranty? A7: No, tube fouling is process-related contamination excluded from warranty. Q8: Why avoid raising heater setpoint to offset fouling? A8: Higher temperature accelerates polymer breakdown and faster carbon buildup.
