What is the most commonly used fiber to produce spunbond nonwoven fabrics?


The most commonly used fiber to produce spunbond nonwoven fabrics is polypropylene. Polypropylene is a thermoplastic polymer that is widely used in the textile industry for its favorable characteristics in the spunbonding process. Some key reasons why polypropylene is commonly chosen for spunbond nonwoven fabrics include:

Melt Spinning Capability: Polypropylene has excellent melt spinning properties, making it suitable for the extrusion process used in the production of continuous filaments.

Strength and Durability: Spunbond nonwoven fabrics made from polypropylene exhibit good strength and durability. This makes them suitable for various applications where a sturdy and resilient material is required.

Chemical Resistance: Polypropylene is resistant to many chemicals, which adds to its suitability for applications where exposure to chemicals is a concern.

Lightweight: Spunbond nonwoven fabrics made from polypropylene are lightweight, yet they provide good coverage and protection. This is beneficial in applications like protective clothing and medical products.

Cost-Effective: Polypropylene is generally a cost-effective material, making spunbond nonwoven fabrics economical for a wide range of applications.

While polypropylene is the most common choice, other thermoplastic polymers such as polyester may also be used in spunbond nonwoven fabric production, depending on specific requirements and desired properties for certain applications.
