The MakerMask: Surge is a three-layer pleated mask designed using spunbond nonwoven polypropylene (NWPP) for the mask body, latex-free ties to secure the mask to the head, and a flexible nose bridge for improved fit. Criteria for mask material selection for MakerMask designs, including breathability, water-resistance, filtration, and compatible with cleaning/disinfection procedures is described in “The Big Four: Criteria for Community Mask Material Selection for COVID-19.”
MakerMask: Surge Instructions
Materiales Requeridas :
- Máquina de Coser
- Freshly washed spunbond NWPP bags ( 3 sheets, 8″ by 9″)
- Bias tape or other latex-free ties (e.g., cotton ties or silicone ties)
- Coffee tin ties, pipe cleaners or coated paper clips
- Tijeras y alfileres
- Cinta métrica o regla
Reúne sus materiales
Las capas deben ser 20.5 cm de altura por 23 cm de anchura.
Top stitch three mask layers
Cose 6 mm desde el borde, completamente alrededor.
Dobla ambos lados y el fondo hacia adentro
Dobla tres lados hacia a dentro aproximadamente 1.25 cm, como se muestra, deja la parte superior abierta para la banda del nariz. Cose estos tres lados doblados a si mismos, aproximadamente 6 mm desde el borde.
Twist three pipe cleaners together
Esto permitará que la máscara se presione hacia abajo sobre el puente de la náriz, creando un sello aceptable.
Note: Instead of pipe cleaners, coffee tin ties or coated paper clips also work well for the nose bridge.
Corte las limpiapipas a la medida
Recorte la material para el puente del nariz un poco más corto que la anchura de la máscara. Si queden con extremos agudos, doblanlas para prevenir heridos a los usuarios.
Dobla la parte superior sobre las limpiapipas tornadas
Posa las limpiapipas 1.5cm del borde, dobla la tela sobre ellas, y cose esto en su lugar. Cose éste canal en ambos extremos para cerrarlo.
Haga tres pliegues para plisar las máscara para expansión
Pleats should be approximately 1/2 inch wide. After pleating, the mask should be approximately 3 1/2 inches long.
If it helps, mark lines on your fabric at 1 ½, 2 ½, 3, 4, 4 ½, and 5 ½ inches from the bottom of your mask. Fold the 1 ½ inch line up to meet the 2 ½ line, crease, and if helpful pin in place on each side. Repeat by folding the 3 inch line up to the four inch line. And finally, the 4 ½ inch line up to the 5 ½ inch line.
Cose estos en su lugar cosiendo las bordes 6 mm del los bordes de nuevo.
Mide los lazos de tela para un ajuste perfecto
Los lazos deben ser bastante largos para atar detrás de la cabeza (~30.5 cm) y sostengan la máscara cómodamente a la cara. Cose los lazos al exterior de la máscara, 6 mm desde el borde.
Ensure breathability before use (for details, see 3 Easy DIY Mask Tests )
Wash/Disinfect mask before each use.
While autoclaving is ideal, home users can simply submerge the masks in boiling water for 10 minutes. Details about the Care and Use of MakerMask: Surge mask designs is available in the example Care and Use User Label (pdf) and in our post the FDA’s face mask labeling requirements, “Label Me a Face Mask.”
Additional information about mask cleaning and disinfection, and the science behind the MakerMask recommendations see: “Fabric Mask Cleaning and Disinfection.”
Fabric Substitutions
In accordance with the WHO Guidance on Face Masks, a three layer mask where the two outer layers are constructed from spunbond NWPP (hydrophobic) and the innermost mask lay (the skin contacting layer) is constructed from an absorbent material (e.g., cotton) may also be acceptable.
