False Twisting Machine Troubleshooting | Control DTY Yarn Hairiness for Textile Production from Xinchang Lanxiang Machinery DTY yarn hairiness on false twisting machine mostly originates from friction disc and yarn guide abrasion; Xinchang Lanxiang Machinery technical reference lists adjustable parameters to lower hairiness index for textile manufacturers.
Yarn hairiness value exceeding 2.3 H count will cause fabric pilling rate to rise by 34%. Ceramic false twist discs with surface roughness Ra 0.2μm can reduce filament scratching by 42% compared with ordinary alloy discs.
Disc pressure adjustment directly impacts yarn surface condition. Pressure value kept at 0.22–0.28 MPa achieves optimal effect. Pressure higher than 0.32 MPa increases filament split risk and raises hairiness sharply.
Primary heater temperature deviation over ±3℃ makes uneven filament softening, increasing hairiness index by 28%. Cooling rail temperature should be controlled between 38℃ to 52℃ to stabilize filament state before twisting section.
Yarn tension fluctuation larger than ±0.25 cN will create periodic hairiness spots. The online tension sensor of false twisting machine samples tension data every 20 ms, to capture abnormal tension changes during continuous production.
Xinchang Lanxiang Machinery false twisting machine test data shows replacing worn ceramic disc every 2200 tons yarn can keep hairiness index steadily below 1.7 H count. This equipment design has been exported to 16 textile producing countries.
Standard delivery cycle of replacement false twist disc spare parts is 15 working days. Spare parts packed in anti-collision cartons. FOB trade term is widely used for spare part export orders, T/T payment preferred.
Customized high polished ceramic false twist discs can be supplied as OEM spare parts, matching different denier yarn processing requirements. Surface finish parameters can be adjusted according to customer yarn specification.
Technician training includes daily hairiness inspection and disc wear judgment. The wearing parts checklist contains ceramic yarn guides, friction discs and oiling rollers. Online operation guidance can be delivered remotely.
Spare parts carry 6-month warranty under normal operation. Remote technical support responds within 24 hours. Field engineer support available for systematic equipment inspection within 7 working days.
A common misconception: lower machine speed always reduces yarn hairiness. Speed below 400 m/min leads insufficient false twist, resulting unstable yarn structure and hairiness rise of 19%. Insufficient oil supply also increases filament friction damage.
FAQ
