How to make a medical mask
Cut a 38 x 19 cm piece out of the fabric. Machine the narrow edges in a zigzag pattern. Fold the fabric in half across the face inside and secure the stitched edges with clips.
On the seam side, use a felt-tip pen to place dots at a distance of 4 cm from the edges. If necessary, move the clips closer to the middle. Sew the fabric along the zigzag to the marks, leaving a hole in the middle. Remove the clips.
Put the blank so that the seam was on top and iron it, straightening the stitched fabric to the sides. Turn the part out on the front side. Stitch the seam along one edge.
Place the part so that the seam is centered. Make a mark on the side of it at a distance of 1.3 cm from the bottom and top of the other, UN-stitched edge. Holding the fabric on the lines, lay it so that they were on the fold, and between this fold and the seam formed a strip (width, respectively, 1.3 cm). Iron the fabric.
Secure the folds to the fabric with clips. Sew the resulting blank on all four edges, removing the clips in the process.
Insert a piece of wire 16.5 cm long into the remaining hole to the fold.
Secure with clips and sew the seam along the side of the wire so that it does not come out.
Turn the workpiece with the hole down. Fold the fabric into an accordion, starting from the edge with the wire. Fix the creases with clips.
Iron the part on both sides and sew along the narrow edges.
Cut two wide strips of fabric that are slightly longer than the width of the mask. Apply them to the narrow edges of the workpiece on the front side. The top and bottom of the fabric should go a little on the detail. Secure with clips on all sides and sew only on the sides.
Bend the sewn parts, bend their narrow edges and double-fold the wide edge. Secure with clips.
Sew these parts on the open wide edges. Cut two 25 cm long strips from the elastic band. Prick a pin on one of them and thread it into the stitched parts on the sides of the mask. Tie a strong knot and hide it. Similarly, secure the second strap.
In the hole on the back side, insert the filter according to the size of the mask.
What to consider
World Health Organization it is recommended to wear a mask in two cases:
1. If you cough or sneeze.
2. If you are healthy but have close contact with a person with these symptoms.
No mask can protect you completely. But it will reduce the risk of infection if you wear it correctly, as well as regularly wash your hands with soap and water or treat with an alcohol-containing antiseptic.
The material from which you plan to make a mask must be:
1. Breathable. This is necessary so that you can breathe freely, and the face under the mask does not sweat.
2. Not rude. First, the rough fabric will irritate the skin. And secondly, it will not be able to repeat the shape of the face, that is, the mask will not fit tightly to the skin.
Try not to touch the mask while it is on your face. If you have to do this, be sure to wash your hands before and after.
As soon as the mask becomes raw (usually within 2-3 hours), replace it with a new one. Ideally, you should change the mask immediately after you have sneezed or coughed inside it. To do this, you should make several masks and carry them in a pack with you.
Fabric masks should be thoroughly washed in hot water with washing powder. It is not yet known at what temperature SARS‑CoV is destroyed‑2. Its closest relative SARS-CoV, which causes atypical pneumonia, died when heated to 56 °C within 15 minutes. Therefore, the hotter the water, the better.
After washing, when the mask is dry, iron it with a hot iron. The well-ironed accessory will be softer and will sit on the face tighter, without folds.
