Fibres; synthetic filament tow, of polyesters

HS v2017 Code: 550120

About fibres; synthetic filament tow, of polyesters

HS code 550120 covers the trade and production of synthetic filament tow made from polyester fibers. This industry plays a crucial role in the global textile and apparel supply chain, providing a key raw material for the manufacturing of various textile products. Polyester filament tow is widely used in the production of fabrics, garments, and other textile-based goods, making it an essential component of the broader textile and fashion industries.

Production process

The production of polyester filament tow typically involves the extrusion of molten polyester polymer through a spinneret, which creates continuous filaments. These filaments are then drawn, cooled, and gathered into a tow or bundle. The tow may undergo further processing, such as crimping or cutting, to create the desired fiber characteristics and properties.

Production inputs

The main inputs required for the production of polyester filament tow include polyester polymer resins, which serve as the raw material. Additionally, the industry relies on specialized machinery and equipment, such as extruders, spinnerets, and drawing and winding systems. Energy sources, such as electricity or natural gas, are also essential for the manufacturing process.

Production outputs

The primary output of HS code 550120 is polyester filament tow, which is then consumed by various downstream industries. This tow is often used as a raw material in the production of 550320 Fibres; artificial filament, tow of viscose rayon, 550330 Fibres; artificial filament, tow of cellulose acetate, and 550390 Fibres; artificial filament, tow, nes, as well as in the manufacture of fabrics, garments, and other textile products.
