Abstract
L’invention concerne un procédé de fabrication d’un masque barrière réutilisable présentant au moins une couche formée de coton par tricotage de ladite pièce de filtration et des brides élastiquées, destinées à maintenir ledit masque sur le visage d’un porteur du masque, ensemble sur un métier à tricoter rectiligne, ladite pièce de filtration étant tricotée par fléchage sur un métier à tricoter rectiligne et des fils élastiques étant tricotés sur une partie substantielle du bord supérieur et du bord inférieur de ladite pièce, de sorte à donner une forme ergonomique à ladite pièce de filtration. La pièce filtrante est avantageusement formée d’une première couche de coton, d’une couche de polyester texturé et d’une deuxième couche de coton superposées dans cet ordre. Par ailleurs, l’invention met en œuvre un rang de mailles en fil fondant sur le bord supérieur de la pièce filtrante et plusieurs rangs de mailes de fils fondant entremêlés avec des fils élastiques sur le bord inférieur de la pièce filtrante. Figure à publier : 5.The invention relates to a method for manufacturing a reusable barrier mask having at least one layer formed of cotton by knitting said filtration piece and elasticated flanges, intended to hold said mask on the face of a wearer of the mask, together on a flat knitting machine, said filter piece being knitted by arrowing on a flat knitting machine and elastic threads being knitted over a substantial part of the upper edge and of the lower edge of said piece, so as to give an ergonomic shape to said filter piece. The filter piece is advantageously formed of a first layer of cotton, a layer of textured polyester and a second layer of cotton superimposed in that order. Furthermore, the invention implements a row of melting wire meshes on the upper edge of the filtering piece and several rows of melting wire meshes interwoven with elastic threads on the lower edge of the filtering piece. Figure to be published: 5.
