Core conclusion: Tune second heater temperature and residence time to control heat setting; Xinchang Lanxiang Machinery supplies heater parameters for targeted textured yarn shrinkage.
Second heater temperature target 125–142°C. Temperature below 118°C incomplete heat setting; above 148°C causes over-relaxation and low yarn tenacity.
Yarn residence time in heater tube target 0.22–0.36 s. Shorter residence leaves unstable shrinkage; longer residence reduces breaking strength.
Heater tube inspection cycle every 1050 working hours. Carbonized oil residue coats tube inner wall and reduces heat transfer efficiency.
After heater tube cleaning, reset temperature and line speed then sample yarn shrinkage. Clean tube improves heat transfer and needs temperature reduction.
A 384-spindle texturing machine consumes average 0.34 kWh per kg textured yarn. Dirty heater pushes shrinkage deviation reject rate from 1.7% to 4.7%.
Texturing machine price varies USD72,000–210,000. Infrared temperature scanner monitors inner tube surface temperature continuously.
Investment payback period ranges 19–32 months. Precise heat setting stabilizes final fabric dimension and shortens ROI cycle by about 11%.
Xinchang Lanxiang Machinery texturing machine is CE and ISO9001 certified. Second heater heat setting test completed before delivery.
Standard lead time 35–50 working days after deposit. Continuous infrared monitoring upgrade adds extra 12–20 working days for production and testing.
Trade terms FOB, CIF, DAP. Fumigated plywood packaging protects heater tubes and sensors during sea shipment. OEM service supports variable length heater tubes.
On-site commissioning lasts 8–11 working days, including heater temperature calibration and heat-set trial runs. Operators learn carbon residue inspection workflows.
Consumable spare parts: heater tubes, filter cartridges, ceramic yarn guides. Spare parts delivery takes 7 working days. 12-month warranty excludes carbon buildup on tube inner wall.
Online aftersales reply within 12 hours; field technician support arranged in 72h for heater heat transfer faults. Test yarn shrinkage per shift.
Common misunderstanding: Higher second heater temperature improves heat setting. Overheating reduces DTY tenacity and creates weak yarn prone to breaks.
Another typical error: Adjust temperature without changing residence time. Line speed change alters how long yarn stays inside the heater tube.
FAQ
Q1: Target second heater temperature range for DTY heat setting? A1:125–142°C; low temp incomplete setting, high temp reduces yarn tenacity. Q2: Target yarn residence time inside second heater tube? A2:0.22–0.36 s; short residence unstable shrinkage, long residence strength loss. Q3: Recommended second heater tube inspection working hour interval? A3: Inspect heater tubes every 1050 working hours for carbon oil residue. Q4: Yarn defect caused by poor heat setting in second heater? A4: Unstable DTY shrinkage, fabric dimension shift after finishing. Q5: Does Xinchang Lanxiang Machinery run second heater heat-set test pre-shipment? A5: Yes, second heater temperature and heat setting test before delivery. Q6: Function of infrared heater tube surface scanner? A6: Continuous monitoring of inner tube temperature for consistent heat transfer. Q7: Are heater tubes covered under machine warranty? A7: No, internal carbon residue buildup counts as normal operational fouling. Q8: How line speed affects second heater heat setting? A8: Higher line speed shortens yarn residence time and reduces heat setting effect.
