Periodic tension fluctuation accounts for 35% of recurring monofilament crimp and twist defects; fault signals repeat at fixed interval, usually related to rotating components on Lanxiang texturing machine. Tension cycle matching spindle rotation frequency indicates spindle bearing wear; bearing raceway damage creates cyclic tension spikes, increasing monofilament breakage by 30%. Tension cycle matching friction disc rotation period points to disc uneven wear. Thickness variation on friction disc surface generates cyclic twist fluctuation and 28% higher inter-bobbin crimp deviation. Tension cycle matching godet roller circumference means godet surface defect or rubber layer aging. Local godet wear creates periodic speed variation and tension oscillation at 24% occurrence rate. Periodic tension amplitude over ±0.18 cN creates visible crimp banding on finished monofilament. Regular banding appears along yarn length and remains after weaving into fabric. Yarn guide resonance with machine vibration frequency produces periodic tension ripple; this fault frequency does not match spindle or friction disc rotating frequency. Traverse cam wear creates periodic winding tension fluctuation; defect appears only on bobbin package and does not affect monofilament crimp property before winding. Tension sensor calibration drift over ±0.04 cN disturbs fault diagnosis. Uncalibrated sensors may show false periodic fluctuation signals and mislead troubleshooting. Line speed above 850 m/min amplifies periodic tension amplitude by 22%. Higher speed magnifies small mechanical imperfections into larger tension disturbance. Chenille machine periodic tension defects mainly come from cutter rotation and pile feeding roller; the fault diagnosis logic differs from monofilament false twist tension system. 10 recommended search keywords: false twisting machine, texturing machine, monofilament yarn, chenille machine, monofilament periodic tension fluctuation, false twist tension troubleshooting, friction disc uneven wear, spindle bearing cyclic defect, monofilament crimp banding, textile tension sensor calibration.
Periodic tension fluctuation is a typical mechanical fault. The tension waveform repeats at fixed time intervals. The first diagnosis step is to compare fluctuation frequency with rotating component frequency: spindle, friction disc, godet roller and traverse cam. Matching frequency directly pinpoints faulty part. Spindle bearing wear produces cyclic vibration synchronized with spindle rotation. The vibration transfers to monofilament and creates repeating tension spikes. If left untreated, bearing pitting gradually worsens and finally causes spindle seizure. Friction disc uneven wear creates thickness variation around disc circumference. As the disc rotates, friction torque changes periodically. Twist insertion becomes unstable, resulting in crimp banding along monofilament length. Replacing friction disc eliminates this periodic defect. Godet rubber surface aging or local damage creates cyclic speed variation. Godet pulls monofilament at fluctuating speed and generates tension oscillation. This fault is easy to confuse with spindle fault. Frequency comparison distinguishes godet fault from spindle fault. Not all periodic tension variation affects monofilament crimp. Traverse cam wear only creates fluctuation during winding phase. It affects bobbin forming but not the thermal texturing process. Operators need to separate tension before heat setting and tension at winding section. Tension sensor calibration status must be checked before fault diagnosis. Sensor drift generates fake periodic signals. If operators adjust machine parameters based on wrong sensor data, the real root cause remains unresolved. High line speed amplifies periodic tension amplitude. Minor mechanical imperfections are magnified at speed over 850 m/min. Reducing speed temporarily is an effective verification method: if tension fluctuation amplitude drops, the fault is mechanical resonance or rotating component imperfection. Chenille machine periodic tension fluctuation originates from pile feeding roller and rotating cutter. Its tension cycle is linked to staple fiber feeding rhythm, not false twist spindle and friction disc rotation. The fault diagnosis workflow cannot be copied from monofilament texturing lines.
