Concentric Bico Thermal Fusion Polyester Staple 6D 65mm from China
Concentric sheath-core bi-component polyester fibers, 6 denier, 65mm staple length, engineered for uniform thermal fusion in needlepunched geotextiles and carpet underlays. The outer copolymer melts selectively to create strong interfiber bonds during hot air or calender bonding. Precisely matches HTS 5503.20.0015 definition for bonding-purpose bi-component synthetics.

Import Tips
• Cross-section morphology (concentric vs eccentric) doesn't affect 5503.20.0015 but document for technical validation
• Geotextile end-use common; avoid Chapter 59 classification by proving raw fiber state pre-bonding
• Large bale imports (>500kg) need proper ventilation certification to prevent moisture degradation
