Bico Polyester Thermal Bonding Staple Fiber 4D 6mm
Bi-component polyester staple fibers with a low-melt copolymer sheath surrounding a high-melt core, cut to 6mm length at 4 denier. Designed specifically for thermal bonding applications where the sheath melts at lower temperatures to fuse fibers without adhesives. Classified under HTS 5503.20.0015 due to their bi-component structure optimized for nonwoven bonding processes.
Thermal Bondable Polyester Bico Staple Fiber 15D 38mm
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.
ES Sheath-Core Bico Polyester Fiber 2D 32mm
Extensible sheath (ES) bi-component polyester staple fibers, 2 denier ultrafine, 32mm length, with copolyester sheath melting lower than PET core for superior bonding.
