Chenille machine feeding speed directly affects finished fancy yarn quality; properly tuned units maintain yarn unevenness below 3.0% while keeping stable hourly production capacity.
When feeding speed rises from 220 m/min to 300 m/min, the hourly output of an 8-spindle chenille machine increases by 34%, yet pile shedding rate climbs by 21% without tension recalibration.
Fiber feeding roller surface roughness Ra 1.6μm provides better fiber gripping effect; roughness higher than 3.2μm causes local fiber over-feeding and thick yarn segments.
Lanxiang False Twisting Machine can pre-twist core yarn before entering chenille machine, reducing core yarn breakage probability by 18% during fiber wrapping operation.
For short staple fiber of 22mm length, the recommended feeding speed window is 240–280 m/min. Speed outside this range raises fiber waste rate above 4.6%.
Pile density inspection requires sampling 12 points per 500 meters of finished chenille yarn. Sampling less than 6 points reduces defect detection probability by 43%.
Workshop air flow over 0.8 m/s disturbs loose staple fiber before wrapping, creating uneven pile distribution and raising yarn defect rate by 25%.
Many chenille production lines use fixed speed settings year-round. Raw material batch variation of 5% in staple fiber fineness needs speed adjustment of 10–15 m/min.
When comparing production schemes, continuous low-speed stable operation reduces total waste by 19% versus intermittent high-speed running with frequent stops.
A common misconception: maximum feeding speed always delivers the highest profit. Excessive speed increases rework volume and offsets gains from higher theoretical output.
