Fibres; synthetic filament tow, of polypropylene
HS v2022 Code: 550140
About fibres; synthetic filament tow, of polypropylene
HS code 550140 covers the trade and production of synthetic filament tow made from polypropylene. Polypropylene is a widely used thermoplastic polymer with a diverse range of applications, from packaging and textiles to automotive components and household items. The synthetic filament tow produced under this code is a crucial raw material for the textile industry, serving as a key input for the manufacture of various fabrics, yarns, and other textile products.
Production process
The production of polypropylene filament tow typically involves a multi-step process. First, polypropylene resin is melted and extruded through a spinneret to form continuous filaments. These filaments are then cooled, drawn, and crimped to create the desired tow structure. The tow is then cut into shorter lengths, often referred to as staple fibers, which can be further processed into yarns, fabrics, and other textile products.
Production inputs
The main inputs required for the production of polypropylene filament tow include polypropylene resin, which serves as the primary raw material, as well as specialized machinery such as extruders, spinnerets, and drawing and crimping equipment. Additionally, energy sources, such as electricity or natural gas, are needed to power the production process.
Production outputs
The primary output of HS code 550140 is polypropylene filament tow, which is a versatile material used in a wide range of textile applications. This tow may be consumed by industries producing 550320 Fibres; artificial filament tow, 550330 Fibres; artificial staple, and 550410 Fibres; synthetic staple, not carded or combed, among others, for the manufacture of various fabrics, yarns, and other textile products.
