Comparison of Polypropylene (PP) and Spunbond-Meltblown-Spunbond (SMS) materials:

Polypropylene (PP):

Material composition:
PP is a plastic. It starts as small pellets that are melted and then formed into thin fibers for use in textiles (spunbond polypropylene SBPP).

Properties:
Moisture resistant: PP is inherently moisture resistant, making it ideal as a base material for nonwovens in healthcare applications.
Colorfast: PP retains colors well, allowing for customization for specific brands or applications.
Key features: Long, loosely woven fibers with large pores.

Advantages:

• Basic moisture resistance
• Excellent durability
• Versatility
• Breathable

Spunbond-Meltblown-Spunbond (SMS):

Material composition: SMS is made of two layers of spunbond polypropylene (SBPP) and a middle layer of meltblown polypropylene (MBPP).

Features:
Enhanced protection: SMS combines the advantages of SBPP with the filtration properties of MBPP material.

Advantages:

• Liquid barrier: SMS has better liquid barrier properties
• Breathable: Still breathable, but with increased protection
• Filtration efficiency: Higher filtration rate compared to SBPP

In summary, while PP is a basic material with good moisture resistance and breathability.
SMS offers better protection due to its layered structure and increased filtration properties, and is stronger and softer due to its layered structure.
When choosing between the two, consider the specific requirements of your application.
