About fibres; synthetic staple fibres, of polypropylene, carded, combed or otherwise processed for spinning

HS code 550640 covers synthetic staple fibres of polypropylene that have been carded, combed, or otherwise processed for spinning. This industry is a crucial component of the broader textile and apparel supply chain, providing essential raw materials for the production of a wide range of textile products. Polypropylene fibres are valued for their durability, resistance to chemicals, and low cost, making them a popular choice for applications ranging from clothing and home furnishings to industrial textiles and nonwoven fabrics.

Production process

The production of synthetic staple fibres under HS code 550640 typically involves several key steps. First, polypropylene resin is extruded into continuous filaments, which are then cut into short, uniform lengths to create the staple fibres. These fibres are then carded, a process that aligns and organizes the fibres, and may also be combed to further refine and straighten the fibres. Finally, the processed fibres are ready for spinning into yarns or for use in other textile manufacturing processes.

Production inputs

The main inputs required for the production of HS code 550640 fibres include polypropylene resin, which serves as the raw material, as well as specialized machinery for extrusion, cutting, carding, and combing. Additionally, energy sources, such as electricity or natural gas, are needed to power the production equipment. Other supporting inputs may include quality control systems, packaging materials, and transportation services to deliver the finished fibres to downstream 650000 Textile, 630000 Apparel, and 560000 Nonwoven industries.

Production outputs

The primary output of HS code 550640 is synthetic staple fibres of polypropylene that have been processed for spinning. These fibres can be used in a variety of textile applications, including the production of 520000 Yarn, 540000 Fabric, and 630000 Apparel products. Additionally, the fibres may be used in the manufacture of 560000 Nonwoven materials, such as geotextiles, filtration media, and insulation materials.
