1. Tensile Strength and Mechanical Stress

Sequin embroidery machines operate at speeds exceeding 800-1000 RPM. This creates significant friction heat and mechanical stress.

  • Polyester 120D/2: Offers superior breaking strength, ensuring that the "Lock-Stitch" remains consistent across a 10,000-meter production run.
  • Cotton Thread: While soft, cotton tends to fray and break under high-speed friction, leading to "Stitch Gaps" that expose the base mesh.

2. Abrasion Resistance and "Sequin Shedding"

The biggest fear for any wholesale buyer is "Sequin Shedding." At Yunfan, our threads are tested for abrasion resistance against the sharp edges of laser-cut sequins. Polyester's synthetic polymer structure ensures that even under repeated wear, the thread does not weaken, maintaining our factory-standard 5.5N attachment strength.

3. Color Consistency in High-Temp Finishing

Embroidery fabric undergoes high-temperature heat-setting (stenter) to lock the dimensions. Polyester threads are "Solution-Dyed" or pressure-dyed at 130°C, ensuring a Grade 4.5 color fastness. They won't bleed onto the metallic or iridescent sequins during the final steaming process.
