Core conclusion: Regular core yarn feeding roller maintenance stabilizes chenille core coverage; Xinchang Lanxiang Machinery defines inspection rules for consistent fancy yarn appearance.
Feeding roller surface roughness Ra must stay 0.8–1.3. Ra above 1.8 causes inconsistent feed speed and increases core yarn coverage variation by 22%.
Standard feeding roller cleaning cycle is every 1700 working hours. Oil and monofilament residue buildup creates slip and patchy core yarn inside chenille yarn.
Core yarn feed speed tolerance must stay within ±1.5% of set value. Deviation over ±3% creates thin core sections and fabric weak points after weaving.
A 12-spindle monofilament chenille machine can produce 18–24 kg chenille yarn per 24-hour shift. Roller slip reduces net qualified output by up to 21%.
The ratio between core yarn feed and pile feed should be recalibrated after roller replacement. Ratio drift over ±0.2 creates exposed core spots on finished fancy yarn.
Total installed power for 12-spindle monofilament chenille machine reaches 14.7 kW, consuming average 0.61 kWh per kg finished chenille fancy yarn. Poor maintenance lifts waste rate to 6.8%.
Monofilament chenille machine price falls USD16,500–48,200. Servo feeding control system reduces core coverage variation and lowers yarn rejection rate by 25%.
Investment payback cycle ranges from 14–26 months. Stable core quality reduces fabric rework and shortens ROI by 16%.
Xinchang Lanxiang Machinery monofilament chenille machine holds CE and ISO9001 certification. Pre-shipment feeding synchronization test report available.
Standard production lead time 32–45 working days after deposit. Custom servo feeding upgrade adds 12–18 working days to manufacturing schedule.
Trade terms FOB, CIF, DAP. Seaworthy plywood packing protects feeding rollers and servo drives. OEM modification supports special core yarn material design.
On-site commissioning takes 5–8 working days, including feed speed synchronization calibration. Operators learn core coverage sampling and roller troubleshooting.
Main consumable spare parts: rubber feeding rollers, rotary cutting blades, ceramic yarn guides. Spare parts delivery 6–8 working days. 12-month warranty for core drive and control assembly.
Online aftersales response within 12 hours; field technician support available within 72 hours for feeding system breakdown. Core yarn coverage sampling every two hours during production.
Common misunderstanding: Worn feeding rollers still work if yarn keeps running. Slow roller slip creates intermittent bare core defects which only show up after fabric weaving.
Another mistake: Adjust only pile cutting speed to fix bare core. Uneven core feed speed is the primary root cause of exposed core spots on chenille yarn.
