Well this is a lot slower than I had hoped. Hopefully there are fully automated plants. They look like they could be produced very quickly if automated. I think mask like this are more effective in stopping an infectious person spreading the virus than they are for keeping a healthy person safe. Mask should be mandatory to eliminate any social stigma.
No, it doesn't stop an infectious person from spreading. Definitely not. It has a flap on ot an lets the air go out without filtration and only filtrates the incoming air. So you would be spreading the disease as of you weren't wearing the mask because of that flap/valve.
@@devrim-oguz They are not moron proof. They must be fitted properly and used properly. If someone has an infectious disease and you have a properly fitted mask, the mask will filter out the preponderance of particles that the other person breathes on you. Bacteria and viruses have to be both infectious and in high enough concentrations to cause you harm. One of any virus in your lung will not harm you, that is how your immune system works, it kills bad guys on its own, it needs to be overwhelmed numerically for you to get ill. It would be nice in this particular time, if you kept your ignorant and ill informed advice to yourself.
@@jessicabrown2483 There are at least two styles of molded masks. Those with one-way outlet valves and those without. However, if everyone is wearing a mask that filters enough virus carrying material, it does not matter if they are one way or two way because everyone is breathing filtered air. The advantage of the one way valve is that it allows hot humid air to escape better than the masks without the valve, thus making it more comfortable. All of course assuming that masks work in the first place. I think they probably do. By the way, telling me you are a doctor or a shoe maker doesn't convey special expertise. You are likely to know more about this than average, but the reason we get second opinions from doctors is that the abilities within the profession are remarkably different. You have no idea what my real credentials are, and I don't care what yours are. What I care about is the ability of someone to think in a logical way.
I thought the exact same thing. However these masks are industrial respirators for dust reduction, not medical items. A chicken feed little plant like this is not sophisticated enough to have after packaging sterilization. But obviously they should. I would certain design a plant where all of these processes were automated and workers never actually touch the materials with bare hands. Then I would have ozone sterilization or high intensity UV light to keep the line sterile.
I don’t think there is a requirement that they be produced in a sterile environment. Consider the delay in shipping and storage and use it must be several months under normal situations. Under current circumstances it would be at least a week. The virus we’re all concerned about only last a few days on plastic.
@@namikpashastudio Probably, but in the first world, it would be fully automated because labour is expensive, dirty and prone to error. I work in automation and I could easily automate all of the activities these people do for between 50 and 100 grand.
@@anthonywarren4207 in my factory(different industry),we have fully automation and semi automation. for fully automatic,usually we use for high runner product while on semi automation we run low quantity order which the cost will be high on fully automation due to setup rejects -
This is a sales video for the equipment! God none of America with any real manufacturing skills understands this because we don't make anything anymore!
Did you mean *United States*? because "America" *THE CONTINENT HAS 35 COUNTRIES* and I am sure most of them specifically the South American ones do understand since they have got plenty of manufacturing industry [Argentina, Brazil, Colombia, Chile]
It is not a foam. It is called meltblown non-woven polypropylene. It is sandwiched between layers of meltblown non-woven low density polyethylene. The polypro is the actual filter material. It has particular static properties that make particles attracted to it. The tex (thickness of the strands) and the density of the non-woven material usually measured in grams per square meter or ounces per square yard, determine what level of filtration is produced. It is pretty easy to make. One needs only a screw type plastic extrusion machine that drives the melted material through tiny nozzles called spineretes. The resulting material is blown onto a drum and cooled and rolled up. Here is a little video of a crude machine to give you an idea of how it works. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-F75Q4wFaOGg.html
@@anthonywarren4207 thanks for the reply. But just want to know how much layer of non woven, SMS, and meltblow is used in it? I suppose total 6 layers, 2 of each around 25/30 gsm. Am I right? But if suppose we press it on vacuum foaming to make bowl type shape. It want damage actual structure of material which we r using for the filtration? According to u which is better, the one sold in market made on automatic ultrasonic machine or the one what we r taking about?
@@mehtavipul9531 That is the tricky bit. If you goal is to actually make NIOSH approved masks that in fact are not just fake labelled the process they have established testing requirements. This is an expensive process and will take hundreds of thousands dollars and a year or so. Forming the masks in my opinion is best achieved with heated male and female tools. My method would be to first make up the layers of the fabric, and then form the mask frame. The ultrasonic welding process is a separate step that is completed down the line. I did a quick and dirty design and could easily produce about 1,500 pieces per hour on a single line. As a textile guy, you may be able to do a better analysis of the materials for tex and density. I am going to receive some 3M masks that are N97. I will then be able to dismantle the product and measure the density and hopefully the tex of the layers. If you have that ability you could perhaps do that yourself. I have zero interest in being in the mask making business. Some friends and I wanted to help our city by making masks on a production line of my design. I needed help from the Canadian government with the very question you are asking. My line was designed to be fully automated and would produce 1,800 masks per hour per line. At the end of the emergency we would have sold the line at cost to someone who wanted to make masks, sold the line to the government at cost for storage in the event of another emergency, or scrapped the line and walk away from our loss. We would have sold the masks at our cost. I go nowhere.
Dear as u have developed this so asking u, even I am not from textile field but yes I am from Nonwoven field from last 20 years and macking shopping bags from Nonwoven. So know little bit about it.
