About fibres; synthetic filament tow, of synthetic materials n.e.c. in heading no. 5501

HS code 550190 covers synthetic filament tow, which is a crucial raw material for the textile and apparel industries. Synthetic filament tow is produced from various synthetic materials, such as polyester, nylon, and acrylic, and is used in the manufacture of a wide range of textile products, including yarns, fabrics, and nonwoven materials. This industry plays a significant role in the global economy, supporting the production of essential consumer and industrial goods.

Production process

The production of synthetic filament tow typically involves the extrusion of molten synthetic polymers through a spinneret, which creates continuous filaments. These filaments are then drawn, cooled, and gathered into a tow, which is a bundle of parallel filaments. The tow may undergo further processing, such as crimping or cutting, to create the desired characteristics for various applications.

Production inputs

The main inputs required for the production of synthetic filament tow include synthetic polymers, such as polyester, nylon, or acrylic, as well as specialized machinery for extrusion, drawing, and tow formation. Additionally, energy sources, such as electricity or natural gas, are needed to power the production process, and water may be required for cooling the extruded filaments.

Production outputs

The primary output of HS code 550190 is synthetic filament tow, which is then consumed by various industries, including 550320 Fibres; artificial filament tow, 540233 Filaments; of polyester, textured, and 540247 Filaments; of polyamides, textured. These industries use the synthetic filament tow to produce a wide range of textile products, such as apparel, home furnishings, and industrial textiles.
