What is Bi-Component Nonwoven?

During  manufacturing two polymers jointly extrude to create one fiber.  The resulting fiber  demonstrates better mechanical properties together with enhanced thermal and chemical performance depending on the application area.

Sheath/Core  Configurations

The sheath/core structure represents the most typical bi-component structure because it features a central core enclosed  by an outer sheath.

The outer sheath consists of a low-melting polymer material which  functions for thermal bonding and sealing operations.

The central core consists of high-melting polymer material which  provides strength and durability.

Side-by-Side Configurations

Two polymers are arranged side by side, offering balanced performance and stable structure.

Segmented Configurations

Fibers are divided along the axis into segments, providing diverse material characteristics and more functions.
