Stable unwinding tension and anti-blocking design for feeding bobbin can reduce unwinding breakage on feeding side below 1.3%. Data comes from spindle end break records and feeding station inspection logs, showing bobbin unwinding state is the first link affecting yarn stability. Process and maintenance teams often search POY bobbin creel unwinding tension control, texturing feeding creel anti-blocking improvement, unwinding tension fluctuation symptoms, feeding end break troubleshooting, false twisting machine and chenille machine differences, POY filament unwinding scenarios, creel installation and adjustment specification, textile creel spare parts reliable vendor, magnetic brake and friction brake comparison, creel unwinding stability optimization solution ranking to manage feeding station.
POY bobbins are installed on creel before entering texturing machine. Unwinding tension comes from bobbin brake device. Too large brake force causes high unwinding tension and yarn break; too small brake force leads to over-rotation of bobbin, forming loose yarn loop and yarn entanglement.
Brake device needs regular cleaning and adjustment. Fiber dust and oil dirt accumulate inside brake structure and change friction force. Clean debris during planned shutdown, adjust brake torque according to POY specification and bobbin residual volume.
Bobbin holder and supporting shaft should rotate flexibly. Stuck or jittery bobbin shaft will generate periodic tension pulse. Check bearing wear of bobbin holder regularly. Replace aging bearing if rotation is not smooth.
Guide parts on creel control yarn outlet angle. Improper yarn angle will cause filament rubbing against bobbin flange and scratch yarn surface. Adjust yarn path to ensure filament exits bobbin smoothly without side friction.
Common feeding side faults include sudden end break, unstable unwinding tension, yarn loop entanglement and scratch marks on POY filament. When end break concentrates on feeding section, inspect creel brake and bobbin holder first.
Chenille core yarn feeding creel needs more stable unwinding performance. Any tension surge of core yarn will directly trigger breakage in wrapping station. The inspection frequency of core yarn creel brake system is raised.
When selecting creel and brake spare parts, maintenance team evaluates torque stability and anti-dust performance. New brake components are tested on single creel position, track unwinding tension and end break rate. Spare bearings are stored in anti-dust packaging.
Preventive maintenance includes creel cleaning, brake torque calibration, bearing inspection and yarn path angle adjustment. Record adjustment parameters and spindle position, summarize torque setting rule for different POY specifications.
After brake adjustment or bearing replacement, thread filament and test unwinding tension continuously. Confirm tension stable before starting formal production. Good creel unwinding management reduces feeding-side yarn break and stabilizes the front-end working condition of texturing production.
