Disposable surgical gowns are used by medical staff for invasive treatment of patients in specialized operating rooms and require strict sterilization. For contaminated blood, body fluids and other infectious substances, wearing disposable surgical gowns can serve as a two-way isolation between medical staff and patients.
SMS non-woven fabric
The material of disposable surgical gown is SMS non-woven fabric, the common colors are blue and green, and the material weight is generally between 30gsm and 60gsm. SMS non-woven fabric is different from ordinary spunbond non-woven fabric. It is a composite non-woven fabric, which is a composite of Spunbond + Meltblown + Spunbond Nonwovens. Because the middle meltblown layer has the properties of bacteria barrier and liquid penetration resistance, SMS non-woven fabric has the advantages of high strength, good filtering performance, no adhesive, non-toxic, and breathable. Through special treatment of equipment, SMS non-woven fabric The cloth can also achieve the properties of three antibodies (antistatic, anti-alcohol, anti-plasma), water repellency, etc., and is widely used to make medical disposable surgical gowns, protective clothing, surgical drapes, medical wraps, and medical bed sheets.
In order to strengthen the bacterial barrier effect, SMS can also be upgraded to SMMS or SMMMS. The double-layer or triple-layer meltblown composite non-woven fabric greatly improves the material’s bacterial filtration and liquid barrier properties, and is often used to make high-level protection requirements, like three resistance surgical gown.
Is SMMMS better than SMS?
Some products in the market are described as having multiple layers of melt-blown layers between the spunbond materials. Though this sounds good, it is not possible to differentiate between the different meltblown layers in the finished product as they end up combining together.
What is more important to consider is the thickness of the meltblown layers. A gown with 5 layers of 0.2 grams of meltblown will have the same effectiveness when compared with another gown with a single 1 gram meltblown layer. It is therefore best to judge the gown’s integrity and quality by the weight of its fabric.
Polyethylene
Polyethylene is a very useful plastic and is used as a fibre to make such items as medical gowns. Polyethylene is a lightweight, durable thermoplastic with a variable crystalline structure (Omnexus, 2021). and is made from the polymerization of ethylene (or ethene) monomer. Low-Density Polyethylene (LDPE) is a very flexible material with unique flow properties that makes it particularly suitable for gowns and other plastic film applications. LDPE has high ductility but low tensile strength, which is evident in the real world by its propensity to stretch when strained.
Polyethylene, like every other polymer, has advantages and disadvantages that make it more suitable for certain uses than others.
