Last updated: April 2026 dataNylon and polyamide filament tow — bundles of continuous synthetic filaments crimped but not yet cut into staple length — is the intermediate form used by fiber converters who cut and process tow into staple fiber on their own equipment. The tow format allows downstream processors to control staple length and crimp characteristics to precise specifications, which is why carpet yarn producers and technical textile manufacturers often prefer importing tow over finished staple. Trade in polyamide tow can be subject to the same Section 301 tariff exposure as other synthetic fiber products depending on origin.

Filament tow gives the importer's converting operation control over the final staple length and crimp level, which can be critical for matching yarn specifications. Finished staple fiber is cut and crimped to fixed parameters by the overseas producer, offering less flexibility but requiring less downstream processing equipment.
Filament tow consists of a large bundle of parallel, crimped continuous filaments that have not been twisted into a yarn structure. The absence of twist and the bulk bundle format are the defining characteristics; twisted or textured filament products classify as yarn rather than tow.
