A Closer Look At The Major Fabric Of Disposable Surgical Gowns

May 09, 2023

 

Disposable surgical gowns play a critical role in maintaining a sterile environment during surgical procedures, protecting both healthcare professionals and patients from potential infections. These gowns are designed to be single-use, ensuring optimum hygiene standards. One of the key factors determining the effectiveness of these gowns is the fabric used in their construction. In this article, we will explore the major fabric used in disposable surgical gowns, its properties, and its significance in maintaining a safe surgical environment.

 

Polypropylene: The Cost-effective Fabric Choice

 

Polypropylene is the primary fabric used in the production of disposable surgical gowns. It is a thermoplastic polymer known for its exceptional properties, making it an ideal choice for healthcare applications. Let's delve into some of the key features of polypropylene and understand why it is widely favored in the medical field.

 

Cost-effective and Disposable:

The affordability and disposability of polypropylene make it an economical choice for surgical gowns. Single-use gowns eliminate the need for laundry and sterilization processes, reducing costs and minimizing the chances of cross-contamination.

 

Barrier Protection:

Polypropylene is a non-woven fabric, meaning it is composed of fibers bonded together rather than being woven together like traditional fabrics. This non-woven structure provides an excellent barrier against fluids, microorganisms, and particulate matter. The fabric effectively prevents the transmission of pathogens from the environment to the wearer and vice versa.

 

Breathability:

While providing a reliable barrier, polypropylene fabric also allows for breathability. The non-woven structure enables the passage of air and moisture vapor, ensuring comfort for the surgical team during long procedures. The breathability feature helps maintain the body's temperature and reduces the risk of heat stress.

 

Lightweight and Flexibility:

Disposable surgical gowns need to offer flexibility and ease of movement for healthcare professionals. Polypropylene fabric is lightweight, allowing for easy donning and doffing without compromising mobility. This characteristic is crucial in surgical settings where precision and agility are essential.

 

Resistance to Liquid Penetration:

Polypropylene exhibits resistance to minor liquid penetration, including blood, bodily fluids, and other aqueous solutions. The hydrophobic nature of the fabric prevents the absorption of liquids, ensuring that potential contaminants remain on the gown's outer surface, reducing the risk of transmission.

 

SMS/SMMS Fabrics: Enhancing Protective Qualities

 

SMS (Spunbond Meltblown Spunbond) and SMMS (Spunbond Meltblown Meltblown Spunbond) fabrics are composite non-woven materials that have gained popularity in the medical industry for their enhanced protective qualities.

 

Spunbond Layer:

The first layer of SMS/SMMS fabric is the spunbond layer, which provides strength, stability, and shape to the gown. This layer is formed by extruding polypropylene fibers and bonding them together. It contributes to the overall structural integrity of the gown.

 

Meltblown Layer(s):

The melt-blown layer(s) in SMS/SMMS fabrics is responsible for providing a high filtration efficiency and fluid resistance. Meltblown technology involves the extrusion of fine, micro-sized fibers that are randomly arranged and then bonded together. The resulting web of fibers creates a dense barrier against liquids and particles, effectively preventing their passage.

 

Barrier Protection and Breathability:

SMS/SMMS fabrics offer excellent barrier protection against liquids, microorganisms, and particles, similar to polypropylene. The melt-blown layer(s) enhance the fabric's ability to repel fluids and filter out bacteria and other contaminants. Despite their enhanced protective qualities, these fabrics still allow for breathability, ensuring comfort for the wearer.

 

Poly-Coated (Laminated Polypropylene) Fabrics: Reinforced Durability

 

Poly-coated or laminated polypropylene fabrics provide an additional level of durability and fluid resistance compared to non-coated materials. In this fabric construction, a layer of polyethylene or polypropylene film is laminated onto a non-woven polypropylene substrate.

 

Enhanced Fluid Resistance:

The poly-coated layer acts as a barrier against fluids, providing an extra level of protection compared to non-coated fabrics. It prevents liquid penetration and reduces the risk of contamination.

 

Strength and Tear Resistance:

The laminated film layer improves the overall strength and tear resistance of the fabric, making it less prone to damage during use. This is especially beneficial during procedures that involve potential hazards, such as sharp instruments.

 

Easy Cleaning and Disposal:

Poly-coated fabrics are typically easy to clean and dispose of, similar to other disposable surgical gowns. They eliminate the need for complex sterilization processes and can be safely discarded after use, reducing the risk of cross-contamination.

 

Choosing the Right Material:

When selecting the appropriate material for disposable surgical gowns, healthcare providers and manufacturers consider factors such as the level of protection required, breathability, durability, and cost. Polypropylene, SMS/SMMS, and poly-coated fabrics each offer unique advantages, and the choice depends on specific application requirements.

 

Conclusion:

 

Polypropylene, SMS, and Poly-coated fabrics remain the major fabric used in disposable surgical gowns. Polypropylene provides the most cost-effective options. SMS/SMMS fabrics provide enhanced protective qualities with high filtration efficiency, while still offering breathability. Poly-coated fabrics, on the other hand, reinforce durability and fluid resistance, making them suitable for procedures involving potential hazards.

 

The variety of fabric options available allows healthcare professionals and manufacturers to select the most appropriate material based on the specific needs of surgical procedures. Regardless of the fabric used, the ultimate goal is to ensure a sterile surgical environment and protect the well-being of both healthcare professionals and patients.
