Draw Texturing Machine High-elastic Yarn Production Parameter Tuning Guide

High-elastic yarn production with draw texturing machines relies on precise stretching ratio and temperature matching, determining yarn rebound rate and fabric stretching performance.
Standard high-elastic textured yarn maintains elastic rebound rate above 93%, suitable for sportswear, swimwear and stretch household textile fabrics.
Stretching ratio set between 1.65–1.75 times achieves optimal molecular orientation, maximizing yarn elastic recovery performance.
Heating temperature increased by 10℃ compared with low-elastic process fully shapes elastic crimp, improving crimp stability by 21%.
Operating speed controlled at 900–1050 m/min balances elasticity forming and production efficiency, avoiding insufficient crimp at ultra-high speed.
Lanxiang Machinery draw texturing machine high-elastic parameter preset library reduces debugging errors and improves finished yarn batch stability.
Tension fluctuation exceeding ±0.8 cN destroys crimp uniformity, raising elastic unqualified rate to over 3.5% in mass production.
Regular heater cleaning every 7 days ensures uniform heating, preventing local insufficient elasticity of single yarn strands.
Workshop temperature stabilized at 24–26℃ reduces thermal interference, controlling high-elastic yarn batch difference within 1.3%.
### FAQ
Q1: What rebound rate qualifies high-elastic textured yarn? A1: Standard elastic rebound rate must reach above 93%.
Q2: What stretching ratio suits high-elastic production? A2: Optimal stretching ratio ranges from 1.65 to 1.75 times.
Q3: What speed balances elasticity and efficiency? A3: Stable production within 900–1050 m/min speed range.
Q4: What tension fluctuation causes elastic defects? A4: Tension drift over ±0.8 cN leads to unqualified elasticity.
Q5: How to stabilize high-elastic yarn batch quality? A5: Fix temperature, clean heater regularly and calibrate tension.
