BACKGROUND OF THE INVENTIONFace Mask has long been considered indispensable in the spread of infection besides preventing airborne infections by absorbing droplets, when someone coughs, talks or sneezes. Thus, Face Masks with ability to eliminate cross-contamination, can be a pivotal element in infection control strategy of a society.
In recent years, the emergence of deadly Viruses with contagion properties are spelling havoc in our societies, resulting in severe straining of the Healthcare Systems as also of the economies. Surging morbidity rates by potentially dangerous Viruses as likes of SARS (Severe Acute Respiratory Syndrome) and Avian Influenza, Ebola, H1N1 and the recent COVID 19 are dooming our future and putting our Civilization to the brink of destruction. The earlier developed Masks, suffered from the problem of secondary infection on account of Viruses adhering to the used Mask and contaminating hands during disposal/changing. Therefore, a Mask is of little use in preventing infection. Efforts to take care of the deficiency led to new developments thereby inspiring Inventors/Community Health Specialists to relook at developing Masks that can control the spread of Viruses in highly effective and Eco-Friendly manner. A number of Masks have been developed in line with complete avoidance of secondary Infections.
PRIOR ARTCN101946990A titled, “Nano silver selenium negative ion anti-bacterial Face Mask for controlling H1N1 influenza” relates to a nano silver selenium negative ion anti-bacterial Face Mask for controlling H1N1 influenza, belonging to the technical field of the production of health textile engineering fabrics Face Masks. At present, the H1N1 influenza globally grinds on, dire threats are brought for the life and the health of Human Beings, once the H1N1 influenza largely grinds on within the Globe, a plenty of Human lives can be captured possibly, and the death toll even exceeds any one World War. The H1N1 influenza is caused by an influenza virus; test researches shows that no microorganism can not be killed by silver within 6 min., thus the silver is a known antibacterial agent capable of killing all bacteria and Viruses. Selenium, germanium and honey serial products capable of enhancing the Human immunity, and nano mixed powder of medical stone, tourmaline and traditional Chinese medicine formations are added into fiber fabrics of a spinning solution to prepare the nano silver selenium negative ion anti-bacterial Face Mask for controlling H1N1 influenza which can achieve the purpose of no treatment of diseased patients but preventive treatment of diseases, wherein the nano mixed powder is capable of releasing trace elements and negative ions.
US20160113336A1 titled, “Face Mask” discusses a mask that has a mask body and a pair of ear straps. The mask body includes an outer layer sheet and an intermediate layer sheet. The outer layer sheet is formed of hydrophobic fibers. The intermediate layer sheet is laid on the outer layer sheet so as to be located on a wearer's side of the outer layer sheet when the mask is worn. The intermediate layer sheet includes a first fiber layer which is formed of polyolefin fibers containing an inorganic antimicrobial agent and a second fiber layer which is formed of polyolefin fibers and has a larger fiber diameter than the first fiber layer. The fiber diameter of the first fiber layer is within a range of 0.5 to 2.8 μm and the ratio of a particle diameter of the inorganic antimicrobial agent with respect to the fiber diameter is within the range of 0.1 to 6.0.
WO2009026725A1 titled, “Antimicrobial compositions and fibres incorporating the same” defines an antimicrobial composition comprising (a) at least two antimicrobial agents having different antimicrobial mechanisms of action and being present in amounts that together provide a synergistic antimicrobial effect or (b) an antimicrobial agent and a surface modifying agent, an antimicrobial masterbatch comprising antimicrobial composition (a) or (b) and a polymer carrier, an antimicrobial fibre composition comprising the antimicrobial masterbatch and a fibre substrate, an antimicrobial fibre comprising a fibre body or a fibre surface having the antimicrobial fibre composition, and a process for producing antimicrobial fibres.
EP2969040A1 titled, “A facemask having one or more nano fiber layers” talk of facemasks and methods utilizing nano fibers. The facemask and methods provided reduce pressure drop and enhance filtration of airborne particles. In one embodiment there is a facemask, comprising: an inner layer comprising nonwoven fiber material configured to contact a wearer's nose and mouth; a middle layer disposed on the inner layer and comprising a nanofiber material; an outer layer disposed on the middle layer and comprising nonwoven fiber material, the facemask having upper and lower edges and at least one pleat configured to fit over a chin of the wearer when unfolded, the at least one pleat configured for folding and unfolding the facemask such that when folded the facemask is configured to assume a generally flat storage configuration and when unfolded the facemask is configured to cover at least the nose and mouth of the wearer.
Whereas, in all the prior arts specified, novel methods to take care of secondary infection using advanced fabrics and chemicals in masks are specified, but usage of artificial fabrics/chemicals entails limit to their usage. In such a scenario, use of a material that is natural as well as having appropriate properties to prevent secondary infection is considered more trustworthy. The present invention is an effort, in that direction.

These and other embodiments of the subject invention will readily occur to those of skill in the art in light of the disclosure herein.
Face Masks as described herein find use in various indications, including in health care, surgery, dental applications, research labs, clean rooms, construction sites, air travel, veterinarian applications, cosmetology, environmental settings and the like. Methods of making and using these Masks also form aspects of this invention.
The recent spread of COVID 19, has initiated the use of Face Masks for each and every person to prevent the spread of the virus. In such a scenario, the use of cloth Face Masks is an alternative, provided, according to FDA, the following points are taken into consideration.
The Mask must cover the nose and below the chin;
It must fit not only snugly but also comfortably against the side of the face;
It must be secured with ties or ear loops;
It must include multiple layers of fabric;
It must allow for breathing without restriction; and
It must be able to be laundered and machine dried without damage or change in shape.
The above properties can be found with cotton fabric and cotton Face Masks and are available in the market easily. However, all these properties are more evident in Face Masks made from Hemp Fabric as well. Hemp Fabric is a type of textile that is made using fibres from the stalks of the Cannabis sativa Plant which has been recognized as a source of extraordinarily tensile and durable textile fibres.
The stalks of the Hemp plant consist of two layers: The outer layer is formed from rope-like bast fibers, and the inner layer consists of a woody pith. For textile purposes only the outer layer of the Cannabis sativa stalk is used. Once the outer layer of bast fibers is stripped from the Hemp plant, it can be processed and made into rope or yarn. Hemp rope is strong and remains renowned as an excellent material for clothing that surpasses cotton and synthetic textiles by most metrics.
Once Hemp is processed into fabric, it has a similar texture to cotton, but it also feels somewhat like canvas. Hemp Fabric is not susceptible to shrinkage, and it is highly resistant to pilling. Since fibres from this plant are long and sturdy, hence Hemp Fabric is not only very soft, but it is also highly durable.
Since Hemp is a lightweight fabric, it is highly breathable, and it also effectively facilitates the passage of moisture from the skin to the atmosphere, and is, therefore ideal for hot climates. It is easy to dye this type of fabric, and it is highly resistant to mould, mildew, and potentially harmful microbes.
Hemp Fabric softens with each washing, and its fibers don't degrade even after dozens of washings. Further, Hemp can be blended with cotton as well as blended with Silk. Blending Hemp with other fabrics can make this textile softer while remaining durable.
The above qualities of Hemp Fibre, makes it ideal for making Face Masks.
The present invention, in view of the above properties of Hemp Fibre, utilizes it for making of Masks.
The terms “hold,” “join,” “secure,” “attach” and derivatives and synonyms thereof refer to any affixing of such structure(s) of the present invention to another structure(s) and may be accomplished by any of several conventional methods. Thus, drawstrings may be secured by use of sewing, by tying or any other suitable mechanism that holds the Mask in place. By way of example and not limitation, these methods include stitching, gluing, heat sealing etc.
First, the general configuration of a Mask for Humans of the first embodiment will be described. The Mask of the first embodiment includes a Mask Body 1 having a substantially oval shape and symmetrically and longitudinally divided into two halves—the left and the right, the left side of the Hemp Mask is denoted by 10 and the right side by 20.
The first layer 190 or the outer most layer, visible to the public eye filters out the heavy particles in the atmosphere. This first layer is made of Hemp Fibre that is woven into a semi-coarse Hemp Fabric. In some embodiments of the invention, the first layer of the Hemp Mask 190 the Hemp Fibre may be woven into many different types of patterns, like square or pinwheel designs. In some other embodiments, the Mask may also include one or more images of flowers, animals and the like, any custom designs like animal faces, fish faces or cartoon characters. This allows the Face Mask of the wearer to stand out in public giving the Face Mask a fashionable twist, thereby encouraging the mass to wear Face Masks voluntarily for their protection, but also the embroidered Face Mask allows the Mass to recognize Masked Government Officials' Emblems during an Emergency crisis.
The second layer 200 is a thick Hemp Fibre fabric which may be used for absorbing water for better filtration or for keeping the face warm in cold weather when the Hemp Face Mask is dry.
The third layer 210 of the Hemp Face Mask comprises of Hemp Fabric which is dense and a durable fabric, made from a double strand of long-fibre Hemp which is wet-spun yarn, woven in directions, causing the Hemp canvas fabric to become the densest. Since, the plied Hemp yarns are both warp and weft, the Hemp Fabric of the third layer is very thick. The third layer 210 of the Hemp Face Mask filters out air particles which the outer layer 190 and second layer 200 are unable to filtrate. Since the Hemp canvas fabric of the third layer 210 becomes denser when wet, it is more adept to filter out air particles like coal dust.
The fourth layer 220 is the innermost layer which touches the skin of the wearer. The innermost layer 220 can either be made from 100% Hemp Fibre, or Hemp and Silk fibre or 100% Silk.
In some embodiments the Hemp Face Mask can have more Hemp Fabric layers added on or fewer fabric layers by removing some layers, depending on the environment the Hemp Face Mask is to be used for.
The four layers of fabric 190, 200, 210 and 220 are attached with each other by means of sowing. The various rounds of stitches are denoted by numerals 30, 40 and 50 in
A pocket 60 is sewn onto on to the inner 190 layer of the Hemp Face Mask on the left side 10 of the Mask. The pocket 60 allows to store items while wearing the Hemp Face Mask, or to tuck the other side of the Hemp Mask inside the pocket 60.
A small pouch 70 is sown at the upper part of the oval Face Mask which coincides with the bridge of the nose, for holding a small spring 80. The small spring 80, is heated up in the center and bent into a V-Shape for using as a nose support and also helps in giving shape and form to the Hemp Face Mask around the bridge of the nose, for better protection from the materials and particles in the atmosphere to enter into the Hemp Face Mask, as well as the small pouch 70 and small spring 80 helps support Eye Glasses on the nose of the Hemp Face Mask.
In some embodiments, a logo, design, name or badge 180 can be sown into the Hemp Face Mask pocket 60.
In an embodiment of the present invention, two pairs of drawstrings namely 120, 130 and 140, 150 (corresponding to members used when the Mask is worn) are provided with the body of the Mask. Referring to
Similarly the drawstrings 140 and 150 are sown and fitted at the bottom right hand side of the Hemp Face Mask and bottom left hand side of the Hemp Face Mask respectively and 140 and 150 are pulled up together and locked together using locking means or the use of a Slipknot, to fit the Hemp Face Mask, on the neck tightly.
These drawstrings are braided from natural Hemp Fibre; wet-spun Hemp yarns and features a hollow core. These drawstrings are soft and flexible and perfect for the use with the Hemp Face Mask.
Generally, the locking means is a toggle lock comprising the bottom of the toggle lock 160 housing a spring for the knob 170 for pushing down to unlock the toggle for adjusting 130 and 140 and in place, along with the other toggle lock for 140 and 150 to go through respectively the locking means is used to adjust the Hemp drawstring cord to allow them properly to be fitted on the neck and the top of the head respectively.
In another embodiment, a pair of drawstrings can be provided instead of two pairs. Referring to
Similarly, another one piece Hemp drawstring 135 also braided from natural Hemp Fibre with wet-spun Hemp yarns featuring a hollow core. The draw-string is soft and flexible and perfect for the use for the Hemp Face Mask and is positioned, near the lower part of the Hemp Face Mask and locked together using locking means comprising the toggle lock 160 and 170, to fit the Hemp Face Mask, on the neck tightly.
A Hemp Fabric padding 100 supports the Hemp drawstrings 130 and 120 on the head of the wearer and also protects the head and hair from rubbing of 160 and 170 against the head of the wearer.
Similarly another Hemp Fabric padding 110 supports the Hemp drawstrings 140 and 150 on the neck of the wearer and also protects the neck from rubbing of 160 and 170 against the neck of the wearer.
The Hemp Fabric padding 100 is provided with a pair of holes 90, 90′ for allowing the drawstrings 130 and 120 to pass through which gets adjusted with the fastening means to be snugly fitted over the head. Similarly the Hemp Fabric padding 110 is provided with a pair of holes 95, 95′ for allowing the drawstrings 140 and 150 to pass through which gets adjusted with the fastening means to be snugly fitted over the neck region of the wearer.
In an embodiment of the present invention the Hemp Fabric drawstrings is fastened with the body of the Mask near the edge by sewing it with the layer of fibres. The sowing is done either with the top layer 190 or with the inner most layer of the Hemp Fabric 220 or in between two fabric layers 200 and 210.
In the event that the drawstrings are sown with the innermost layer of 190, a small fabric 155 with stitching 145 is sown over the stitched drawstrings 125, 135, 130, 120, 140 and 150 mainly for providing a smooth cover against the rubbing of the drawstrings with the facial skin of the wearer and additionally to provide aesthetic covering to the sown drawstrings.
In some embodiments of the present invention, the Hemp Face Masks can be designed to be worn by the animals especially dogs and horses. The Hemp Mask for animals not only prevents insects from entering the nose of the animals but also helps in filtration of particulate matter as well as from other dog bites apart from keeping the animal's face warm during winters.
