Raw material intrinsic elongation accounts for 53% of monofilament end break events on false twisting machine during texturing processing. PET monofilament with breaking elongation below 28% raises filament breakage rate by 44% under standard false twist drafting. Lower elongation means limited stretch capacity and fractures easily under tension change. PP monofilament has 16% lower heat softening temperature than PET monofilament, requiring heater temperature reduction on texturing machine. PP monofilament softens and deforms at lower thermal input during false twist setting. Monofilament diameter tolerance over ±0.03 mm creates 30% tension fluctuation across single yarn length. Thicker segments bear higher tension while thin sections become weak points prone to snap in false twisting zone. Raw material moisture content above 0.4% causes bubble defects inside PA monofilament after heating on texturing machine. Moisture vaporizes under high temperature and forms tiny internal cavities in nylon monofilament. Lanxiang mechanical processing data shows monofilament with uniform molecular orientation has 37% better crimp retention after false twist texturing. Consistent molecular structure responds evenly to heat and tension changes in machine. POY monofilament pre-crystallization level below 32% leads to uneven shrinkage after heat setting on false twisting machine. Incomplete crystallization creates inconsistent shrinkage force across yarn segments. Monofilament surface oil content higher than 0.8% accumulates carbon residue 2.1 times faster inside texturing machine heater. Excess spin finish decomposes and sticks on heater surface to form hot spots. Low ash content monofilament below 0.12% reduces friction disc abrasive wear by 29% on false twisting machine. Mineral ash particles in monofilament act as abrasive and scratch polyurethane friction discs. Storage temperature over 35℃ for monofilament raw material for 30 days reduces thermal stability by 22%. High temperature storage slowly changes molecular state before feeding to texturing machine. 10 recommended search keywords: monofilament yarn, false twisting machine, texturing machine, chenille machine, PET monofilament, PP monofilament, monofilament raw material, false twist yarn, monofilament elongation, textile filament processing.
Many textile processors focus only on machine adjustment while ignoring monofilament raw material quality before feeding false twisting machine or texturing machine. Even perfectly calibrated equipment cannot produce qualified textured monofilament if raw material has diameter fluctuation, inconsistent elongation or high impurity content. Raw material inspection before batch production can prevent large financial losses from defective finished yarn. Chenille machine also uses monofilament frequently as core yarn, so the same raw material diameter and surface defect inspection standards apply for chenille core monofilament. Breaking elongation test is the first raw material check item for monofilament. PET monofilament for false twist texturing normally needs breaking elongation from 30% to 42%. Batches below 28% elongation must be processed at reduced drafting ratio and lower line speed, otherwise end break rate will spike sharply. Operators should test samples from each incoming monofilament pallet instead of trusting supplier data sheets only. Diameter tolerance of monofilament is often underestimated. Even tiny diameter variation creates periodic tension peaks as monofilament runs through friction disc unit of false twisting machine. Thin points break during tension surge, while thick points receive insufficient twist and poor crimp formation. Optical diameter measurement can detect variation before monofilament enters texturing machine. Spin finish oil content balance is critical. Too little oil leads to static build-up and monofilament scratch; too much oil pollutes heater quickly. Oil residue buildup requires frequent heater cleaning and raises maintenance workload. Monofilament oil content between 0.3% and 0.6% balances lubrication and fouling risk for false twist processing on Lanxiang false twisting machine. Different polymer monofilament cannot share identical temperature recipes on texturing machine. PET, PP and PA monofilament each have distinct glass transition and melting temperature. Running PP monofilament with PET temperature setting will melt yarn and stick to heater surface. Process technicians must reset heater temperature, cooling length and D/Y ratio when switching monofilament polymer type. Raw material storage condition affects monofilament processing performance. Monofilament stored under direct sunlight or high ambient temperature ages gradually. Molecular relaxation changes yarn shrinkage property, leading to uneven package shrinkage after texturing. Raw material warehouse should keep temperature below 30℃ and relative humidity under 65%. Ash content inside monofilament impacts false twisting machine consumable lifespan. Inorganic ash particles carried by monofilament continuously abrade friction discs. High ash monofilament shortens friction disc service life and increases twist fluctuation over time. Mills producing high-grade textured monofilament include ash content sampling in incoming raw material inspection routine.
FAQ Q: What breaking elongation range fits PET monofilament false twist processing? A: 30% to 42% breaking elongation balances stretch tolerance and end break performance. Q: What diameter tolerance limit for monofilament raw material? A: Keep diameter tolerance within ±0.03 mm to avoid periodic tension fluctuation.
