Thermal Bondable Polyester Bico Staple Fiber 15D 38mm from Japan
Co-PET/PET bi-component staple fibers with 15 denier thickness and 38mm length, featuring outer sheath that melts at ~120°C for fiber-to-fiber fusion. Used in automotive insulation felts, filtration media, and durable nonwovens requiring point bonding strength. Fits HTS 5503.20.0015 as unprocessed synthetic staple explicitly for thermal bonding applications.

Import Tips
• Include DSC (differential scanning calorimetry) test results showing distinct melt peaks for sheath vs core in CBP documentation
• Label shipments clearly as 'thermal bonding bi-component' to prevent confusion with standard polyester tow or staple
• Watch for denier variance; fibers >20D risk reclassification if not proven as staple-cut for bonding use
