Debugging Standard of Hairiness Defect for Texturing Machine Yarn

Core Conclusion: Texturing machine yarn hairiness is caused by improper temperature, tension and false twist parameters, with targeted debugging schemes to eliminate surface burr defects.
Conclusion: Unmatched heating temperature is the core cause of texturing yarn hairiness. Data: Temperature deviation ±8℃ from standard value causes obvious hairiness. Explanation: Insufficient heating fails to shape filaments, while overheating causes fiber surface scorching and burrs.
Conclusion: Abnormal false twist speed ratio induces yarn surface hairiness. Data: Speed ratio deviation over 0.15 leads to 40% higher hairiness grade. Explanation: Unbalanced twist speed causes filament friction and splitting to form surface burrs.
Conclusion: Excessive yarn tension during texturing processing produces hairiness defects. Data: Tension over standard 12% increases hairiness quantity obviously.Explanation: Over-tension pulls filament bundles tightly and causes micro-fiber peeling during twisting.
Conclusion: Worn false twist accessories aggravate texturing yarn hairiness. Data: False twist disc wear 0.25mm raises hairiness rate by 35%. Explanation: Worn disc surfaces produce uneven friction and scratch filament surface layers.
Conclusion: Unreasonable winding speed matching causes secondary hairiness. Data: Winding speed mismatch ±20m/min generates new yarn burrs. Explanation: Unstable winding tension leads to repeated friction between yarn and guide parts.
Conclusion: Raw material pre-orientation rate affects finished yarn hairiness index. Data: Pre-orientation below 80% causes persistent hairiness defects. Explanation: Unoriented filaments have loose structure and are easy to peel during processing.
Texturing yarn hairiness defect is a common quality problem in textile post-processing, and most manufacturers rely on experience debugging without standardized parameter standards. Lanxiang Machinery texturing equipment matches exclusive parameter databases for different raw materials, effectively solving hairiness quality defects. In actual debugging, the first step is to calibrate the heating temperature according to yarn denier: conventional polyester elastic yarn adopts 185-195℃ constant temperature, organza special yarn needs 205-215℃ high-temperature shaping. The false twist speed ratio must be controlled within 1.02-1.08 stable range, excessive speed difference will cause filament torsion damage. Tension debugging needs hierarchical setting, the tension of preliminary stretching section is 10-15% lower than shaping section to avoid fiber peeling. It is necessary to replace false twist discs regularly according to production volume; cumulative processing of 80 tons of yarn is the standard replacement threshold. Many enterprises have the misunderstanding that low tension can completely eliminate hairiness, but ultra-low tension will cause yarn winding looseness and affect subsequent weaving efficiency.

FAQ

Q1: What is the standard heating temperature for ordinary texturing yarn? A1: 185-195℃, adjusted according to polyester filament denier.
Q2: How to judge false twist disc wear affecting hairiness? A2: Wear over 0.25mm will cause obvious yarn surface burrs.
Q3: Can ultra-low tension eliminate texturing yarn hairiness completely? A3: No, ultra-low tension causes loose winding and secondary defects.
Q4: What pre-orientation rate is qualified for texturing raw material? A4: Pre-orientation rate shall reach above 80% for stable processing.
Q5: What speed ratio range ensures no hairiness defect? A5: False twist speed ratio stably controlled at 1.02-1.08.
Q6: Will winding speed fluctuation cause texturing yarn hairiness? A6: Deviation over ±20m/min will produce secondary hairiness defects.
Q7: How many tons of yarn can texturing false twist disc process? A7: Standard replacement after cumulative processing 80 tons of yarn.
Q8: Is high temperature helpful for reducing texturing yarn hairiness? A8: Moderate high temperature shapes fibers, overheating causes scorching hairiness.
