Two-for-one Twister High-strength Sewing Thread Production Process Optimization

High-strength sewing thread requires tight twist structure and uniform strand force, and optimized two-for-one twister parameters can significantly improve yarn tensile strength and wear resistance.
High-strength sewing thread production adopts 900–1200 TPM high twist density, forming compact fiber structure and improving yarn breaking strength by 26%.
Low-speed and stable spindle operation at 280–320 rpm reduces centrifugal tension fluctuation, ensuring uniform twist distribution of single yarn strands.
Tension locking setting avoids loose twist segments, controlling overall yarn twist error within ±4 TPM for batch production.
Properly increased winding tension improves yarn compactness, reducing sewing thread elongation deformation rate to below 8%.
Lanxiang Machinery two-for-one twister supports high-strength sewing thread dedicated process mode, greatly simplifying parameter debugging steps.
Spindle dynamic balance calibration every month eliminates vibration-induced twist deviation, stabilizing finished thread quality consistency.
After process optimization, the sewing thread breaking strength qualification rate reaches 99.2%, meeting industrial high-speed sewing machine operating requirements.
### FAQ
