Why are SMS nonwovens suitable for the medical industry?
Jun 28 , 2023

Nonwovens are formed by intertwining fibers or filaments using mechanical, thermal or chemical methods, thereby bonding sheets or web structures together. Nonwovens are usually made of composite or synthetic materials such as polypropylene. Spunbond - Meltblown - Spunbond or SMS is the most commonly used medical nonwoven fabric in the industry.

SMS materials are made by combining spunbond nonwovens and meltblown nonwovens. By layering the two together, manufacturers can leverage the best of both products to create a material with high tensile strength, excellent barrier properties, breathability, softness and light weight.

Spunbond the process of dispersing spun fibers into a web by means of a deflector or an air stream, it is a thermal bonding method that does not use any chemicals and has long been used in the production of diapers, protective clothing, hygiene products and more.

Meltblowing The process of blowing hot air onto molten thermoplastic resin, which is extruded through a linear die containing hundreds of holes, resulting in the formation of a fine-fiber, self-adhesive nonwoven web. Meltblown products are ideal for making absorbent materials such as filters or wipes.
