Comparison
Cohesive CIBS vs. ultrasonic welding
Ultrasonic welding is a proven bonded-seam technique for compatible thermoplastics. Cohesive CIBS goes further — fusing at the molecular level via inline lamination.
Cohesive CIBS
Ultrasonic welding
Fusion depth
Molecular fusion via inline lamination.
Surface fusion via high-frequency vibration.
Materials compatibility
Woven and knit shells, linings and insulation.
Thermoplastic-compatible fabrics only.
Design flexibility
Reversible, ultra-clean inside and out.
Clean seam, but limited by thermoplastic constraint.
Barrier integrity
Uniform composite barrier across the garment.
Surface-fused seam; local performance depends on ultrasonic control.
Recommendation
Ultrasonic welding has a valid role in thermoplastic-specific garments. Cohesive CIBS is the broader-spectrum bonded-seam pathway for performance, protective and designer apparel.
