Non-woven fabric! What is it? There is an immense variety of medical face masks, be it for daily protection against COVID or medical practices, but when choosing the best reliable fabric, the first question comes; what makes a good quality face mask? What makes a good quality mask?
In general, there there’s no such fake mask; it’s hard to tell whether it’s good or bad; so different tests to conduct to test the actual quality of face masks. Those tests were;
Blood penetration resistance test – It takes normal human blood pressure at 120 mm mercury to shoot at the mask; the whole idea is that blood will not penetrate through a mask.
Bacterial efficiency test – The second test is bacterial filtration, as it tests how efficiently the mask can filter bacteria, so the usual standard or recommended minimum filtration rate is 95%
Particle Filtration test – For this test, the face masks were filtered out with particles whose r4ecomended filtration size was 0.1 micron or PMO.1. if you compare with n95, it tosses out 2.5 microns or pm 2.5
The other two tests are the breathability and permeability test. After all tests, it was concluded that a good quality face mask could fulfill all US and European standards. Usually, masks should be kept in a cool, dry environment. Since the primary purpose of wearing any fabric face mask is to protect oneself from the environment.
Let’s talk about a particular fabric of face masks; then why does nonwoven fabric stand on top? The increasing demand for this fabric has compelled retailers to facilitate buyers and customers by offering wholesale nonwoven fabric medical masks wholesale.
Why Non-woven fabric?
Because the nonwoven materials (NMs) suits best for medical applications, as it provides numerous advantages in terms of material properties and user requirements, it further ensures the safety of the patient and the entire medical staff because of its superior levels of infection control, efficiency, and sterility.
Moreover, it has higher flexibility, shorter production cycles, versatility, and lower production costs, making it highly demanding for medical applications. During the previous quite a while, dry-laid, melt blowing, spunbonding, hydroentangling, air laying and checking, warm holding, needle punching have become significant advancements for the arrangement of NMs for clinical applications.
Do you know the insight of nonwoven polypropylene fabric? Here’s the guide discussed below;
Insight Into Non-Woven Fabric
There are few challenges while sewing a nonwoven fabric material mask; the common one is that you can’t iron it. From where does the notion of this fabric come to any idea? In early November, Health Canada came out with a recommendation to use a third layer, an inner layer of nonwoven polypropylene. It’s a combination of cotton, nonwoven polypropylene, and again cotton.
The World Health Organization suggests having nonwoven polypropylene on the outside and potential combination, but at the very least, a middle layer should be nonwoven polypropylene.
Do you know about spun-bond nonwoven polypropylene? This fabric is washable instead of the melt-blown polypropylene, reserved for our healthcare workers, for their PPES like n95, and so on.
Sewing Non-Woven Polypropylene Mask
For the cloth mask, the spun bond is nonwoven considers along with the weight of the mask. When it comes to sewing the nonwoven polypropylene mask, the main suggestion is to use something in the range of 70 grams per square meter. How would you know since every supplier will provide you with the number of grams per square meter, and it’s pretty easy to measure?
If you have a kitchen square, take a square meter of your fabric and weigh it; that’s your gram per square meter.
This was a slight peak into an insight into the nonwoven fabric mask. Now let’s move on to other suggested face mask materials that the World Health Organization highly recommends.
Recommended Face Mask Material BY WHO’s
To be clear, fabric masks are not personal protective equipment. They aren’t recommended for use by health workers in healthcare settings, nor for vulnerable populations like people who are 60 above or those with underlying medical conditions; they’re always supposed to be wearing medical masks.
The fabric masks are intended for source control. Suppose your source for a second and mask is here to protect those around you. The Non- woven fabric mask act as a barrier between the mouth, nose, and surrounding environment. Still, the study which evaluated the effectiveness of various types used to make masks identified that fabric masks should ideally have three layers;
The outermost layer should be hydrophobic as well. This means fabric tends to repel droplets and moisture, and this can be made of synthetic material like polyester or a blend of polyester and cotton. Again, this can be found in a knit pattern clothing item.
The inner layer comes in direct contact with your face. And it has to be hydrophilic material that can easily absorb droplets from your exhaled breath. An example of this material is cotton. It chooses a light color like white which can help determine if soiled or wet. An excellent place to find this is woven or knit material.
This can be an insert or can be another fabric layer.
The middle layer should go into a pocket between the inner and outer layer and act as a filter; it should ideally compose of a hydrophobic material, and become a strip of polypropylene fabric which is spun bond non-woven fabric material.
These three are the most recommended layers of medical or any protective face mask that can provide optimal filtration and breathability. There are other types of materials to use, but one thing must not forget that;
Whenever you design a fabric mask, always ensure that it is effective at containing droplets and allows your breath easily. The fabric fibers must balance not being too loose. As it enables traveling droplets through the material and not too tight, which can restrict the ability to breathe.
To conclude, in light of the entire discussion above touching various aspects from good face mask quality, to suggested face mask fabrics by WHO, and insight of nonwoven fabric, now it won’t be wrong to justify that it is the excellent quality face mask that ticks all boxes of fundamental requirement.
