What is SMS gown material?

SMS gown material is a type of nonwoven fabric used in the manufacturing of medical gowns, including isolation gowns and surgical gowns. The term "SMS" stands for "Spunbond-Meltblown-Spunbond," which refers to the three layers of material that make up this fabric. Each layer serves a specific purpose in enhancing the fabric's properties for use in healthcare settings:
Spunbond Layer (S): The outer and inner layers of SMS fabric are typically made of spunbond polypropylene. This layer provides strength and durability to the fabric while allowing it to remain breathable and comfortable for the wearer.
Meltblown Layer (M): The middle layer consists of meltblown polypropylene fibers. This layer is responsible for the fabric's filtration and barrier properties. It serves as a barrier against fluid penetration and provides protection against microorganisms and particles.
Spunbond Layer (S): The final layer, like the outer layer, is made of spunbond polypropylene. It adds another layer of strength and durability to the fabric, ensuring that the gown maintains its integrity during use.
SMS fabric is popular in the healthcare industry due to its excellent combination of properties:
Fluid Resistance: The meltblown layer provides a high level of fluid resistance, making SMS gowns effective at repelling blood, bodily fluids, and other liquids, reducing the risk of contamination.
Breathability: Despite their fluid resistance, SMS gowns remain breathable, allowing for comfort during extended wear.
Barrier Properties: The meltblown layer acts as an effective barrier against microorganisms, providing protection for healthcare workers and patients.
Tear Resistance: SMS gowns are designed to be tear-resistant, ensuring they maintain their integrity during use.
Comfort: The use of polypropylene materials makes SMS gowns lightweight and comfortable for wearers.
Durability: SMS fabric is known for its durability, which is important in healthcare settings where gowns may be subjected to stress and movement.
Non-Linting: SMS fabric is non-linting, which helps maintain a clean and sterile environment in healthcare facilities.
Due to these properties, SMS gowns are commonly used in healthcare settings, including during surgeries, patient care, and procedures where healthcare workers need protection against fluid exposure and potential contamination. They provide an effective barrier against fluids and microorganisms while offering comfort and durability.
