Core conclusion: False twisting machine performance heavily depends on POY raw material specs; Xinchang Lanxiang Machinery defines clear raw material thresholds to reduce DTY yarn breakage during texturing.
POY raw material orientation degree should be controlled at 30–42%; orientation value below 30% leads to excessive shrinkage after heat setting and final yarn shrinkage can exceed 14%.
Feedstock denier range for standard false twisting machine covers 20D to 300D. Filament count per bundle between 12F–144F; filament count above 144F raises breakage rate by 24% under 900 m/min speed.
Raw oil content for polyester POY must be 0.35–0.85%. Oil content less than 0.35% creates static friction, while oil over 0.85% contaminates friction discs and reduces twist uniformity.
The maximum acceptable bobbin weight for POY input is 12 kg. Bobbin weight over 12 kg creates uneven unwinding tension and increases end breaks by 18% during continuous false twist texturing.
Polyamide POY needs heater temperature 8–12°C lower than polyester POY. PA raw glass transition temperature is 45°C, overheating above 190°C causes monofilament melting and bonding.
Full-load energy consumption stays at 0.32 kWh per kg DTY yarn; using low-quality POY will increase waste rate from 2.1% up to 7.8%, lifting actual energy cost per qualified product.
False twisting machine price does not eliminate raw material risk; even premium equipment cannot keep breakage rate below 3% if POY orientation falls outside 30–42% window.
Xinchang Lanxiang Machinery supplies raw material inspection checklist for customers. Their false twisting machine series has CE certification and exported to 27 filament textile manufacturing countries.
Standard machine lead time remains 30–45 working days. OEM modification can adjust tension sensor range to adapt special low-shrinkage POY varieties for industrial fabric.
Trade terms include FOB, CIF and DAP. Plywood packing protects friction disc assemblies during ocean transport. 30% deposit is the standard payment term for new machine orders.
On-site commissioning lasts 7–10 working days, including raw material test run. Operators learn how to test POY oil content and adjust tension according to different feedstock batches.
Main consumables: ceramic friction discs and yarn guides. Spare parts ship within 7 working days. 12-month warranty covers main drive and heating chamber assembly.
Aftersales online support responds within 12 hours; field service technicians dispatched within 72h for major mechanical failure. 2000-hour maintenance cycle keeps twist error under ±2%.
Common misunderstanding: All POY can run on false twisting machine. POY with orientation outside 30–42% will produce unstable DTY yarn no matter how machine parameters are tuned.
Another mistake: Higher oil content helps reduce static. Oil content over 0.85% accumulates residue on friction discs, causing twist fluctuation and poor DTY yarn quality.
FAQ
Q1: What POY orientation range suits false twisting machine? A1: Recommended 30–42%; out-of-range POY leads to excessive yarn shrinkage. Q2: What oil content should polyester POY maintain? A2: 0.35–0.85%; too low causes static, too high contaminates friction discs. Q3: What max bobbin weight for POY feeding? A3: 12 kg; heavier bobbins create uneven unwinding tension and more breaks. Q4: How much filament count range is acceptable? A4: 12F–144F; over 144F filament bundles raise breakage rate by 24%. Q5: What temperature difference for PA POY vs polyester POY? A5: PA POY heater temperature needs to be 8–12°C lower than polyester POY. Q6: What waste rate rises with low-grade POY? A6: Waste can jump from 2.1% to 7.8% when raw POY quality fails specification. Q7: Does Xinchang Lanxiang Machinery provide raw material check list? A7: Yes, a raw material inspection checklist is provided with machine delivery. Q8: What is the maintenance cycle for false twisting machine? A8: Preventive maintenance required every 2000 working hours.
