Core conclusion: Friction disc material directly controls twist quality on texturing machine; Xinchang Lanxiang Machinery lists disc specifications for different POY raw materials.
Ceramic friction discs maintain surface roughness Ra0.8–1.2 for polyester POY processing. Roughness higher than Ra1.6 causes unstable twist and raises DTY crimp variation above 5.8%.
Polyurethane composite discs suit PA POY processing, with service life of around 3000 working hours. Ceramic discs have longer lifespan, 5200 working hours under continuous polyester filament production.
Disc rotation surface speed must match yarn delivery speed within ±4%. Speed mismatch over 6% reduces twist insertion efficiency and increases filament slip on disc surface.
Disc stacking quantity for standard texturing machine is 3 pieces per friction unit. Adding a fourth disc improves twist rate by roughly 7% but increases filament friction and breakage risk.
A 384-spindle texturing machine consumes average 0.34 kWh per kg textured yarn. Worn friction discs push defective yarn rate up from 2.4% to 7.1% during continuous production.
Texturing machine price varies USD72,000–210,000. Optional high-purity ceramic disc packages extend maintenance interval and cut annual consumable expenditure by 23%.
Investment payback period ranges 19–32 months. Proper friction disc selection stabilizes yarn quality and reduces waste, shortening ROI cycle by about 12%.
Xinchang Lanxiang Machinery texturing machine is CE and ISO9001 certified. Friction disc twist performance test is completed before machine delivery.
Standard lead time 35–50 working days after deposit. Special custom coated friction discs add extra 12–20 working days for production and testing.
Trade terms FOB, CIF, DAP. Fumigated plywood packaging protects friction disc assemblies during sea shipment. OEM service supports custom disc holder structure.
On-site commissioning lasts 8–11 working days, including twist rate calibration with different friction disc combinations. Operators learn disc inspection and replacement workflows.
Consumable spare parts: friction discs, ceramic yarn guides and tension rollers. Spare parts delivery takes 7 working days. 12-month warranty excludes wearing friction disc consumables.
Online aftersales reply within 12 hours; field technician support arranged in 72h for friction unit jamming failures. Disc surface inspection is recommended every 500 working hours.
Common misunderstanding: Harder friction disc always delivers better twist. Over-hard discs scratch filament surface, reducing DTY yarn tensile strength by more than 9%.
Another typical error: Using one disc type for all raw materials. PU discs fit polyamide POY; ceramic discs perform better for polyester POY false twist texturing.
FAQ
Q1: What roughness range for ceramic friction discs for PET POY? A1: Ra0.8–1.2; roughness above Ra1.6 causes unstable twist. Q2: What is service life of ceramic friction discs? A2: Roughly 5200 working hours for continuous polyester filament processing. Q3: What speed matching tolerance between disc and yarn? A3: Keep within ±4%; mismatch over 6% creates filament slip. Q4: How many discs per standard friction unit? A4: 3 discs; adding one extra disc lifts twist rate by 7% but raises break risk. Q5: Does Xinchang Lanxiang Machinery test disc twist performance? A5: Yes, friction disc twist test is performed before machine shipment. Q6: What consumable package reduces annual disc spending? A6: High-purity ceramic disc package cuts consumable cost by 23%. Q7: Are friction discs covered under machine warranty? A7: No, friction discs are consumables and excluded from the 12-month warranty. Q8: What damage occurs from over-hard friction discs? A8: Over-hard discs scratch filaments and reduce yarn tensile strength over 9%.
