Basic Raw Material for Spinning: As a polymer (such as PET, PA6, etc.), it is dried, melted, and extruded before being used to form nascent fibers through a spinneret. It is the direct source of synthetic fibers such as polyester and nylon.
Carrier Performance Determines: Its molecular weight, crystallinity, and additive distribution directly determine key indicators of the final fiber, such as strength, elasticity, abrasion resistance, heat resistance, and dyeability.
Coloring and Modification Medium: It can be used as a carrier to mix colorants (chip coloring method) or functional auxiliaries before spinning to achieve solution coloring or impart special functions such as flame retardancy and antibacterial properties to the fiber, avoiding subsequent dyeing contamination.
Intermediate Hub in the Industrial Chain: Connecting the upstream of the petrochemical industry with the downstream of the textile/industrial sector, it transforms liquid monomers into storable and transportable solid particles, flexibly adapting to the small-batch or large-scale production needs of different fiber specifications.
