Nylon 6 Filament Tow
Synthetic filament tow made from nylon 6 polyamide, used primarily for crimping into staple fibers for textile applications like apparel and carpets. It falls under HTS 5501.19.00.00 as 'other' synthetic filament tow of nylon or other polyamides, excluding high-tenacity types. This uncrimped tow is supplied in continuous form for further processing.
Nylon 6,6 Filament Tow
Filament tow produced from nylon 6,6 polyamide, ideal for conversion into fibers for industrial fabrics and upholstery. Classified under HTS 5501.19.00.00 as other nylon/polyamide tow, not high-tenacity. The continuous uncrimped structure distinguishes it from staple fibers.
Polyamide 11 Filament Tow
Filament tow from polyamide 11 (e.g., Rilsan), used in technical textiles and brush fibers due to its flexibility. HTS 5501.19.00.00 covers this as 'other' polyamide tow excluding high-tenacity variants. It remains in continuous bundle form before crimping.
Industrial Nylon Tow for Carpet Fibers
Heavy-denier nylon filament tow designed for cut-pile carpet manufacturing, supplied in bales for crimping. Falls under HTS 5501.19.00.00 as other synthetic filament tow of polyamides. Not high-tenacity, intended for textile fiber production.
PA6 Filament Tow for Apparel Fibers
Fine-denier polyamide 6 (PA6) filament tow for spinning into yarns used in hosiery and knitwear. Classified in HTS 5501.19.00.00 as other nylon tow, pre-crimping stage. Meets statistical notes for unprocessed synthetic tow.
Nylon Tow for Brush Bristles
Coarse filament tow of nylon polyamide for manufacturing brush and broom filaments. Under HTS 5501.19.00.00 as other synthetic tow of polyamides. Supplied uncrimped for cutting into bristles.
