Abstract

The invention relates to a mouth-and-nose covering having at least three flexible air-permeable layers arranged parallel to one another, of which one layer (10) faces the body of the wearer and covers the mouth and nose area during use, having a connection region in which the layers are connected to one another and which runs around in the edge region or adjacently to the edge region of the mouth-and-nose shield, at least one of the middle layers being provided with bacterial filter material. At least the layer (10) adjacent to the body of the wearer of the mouth-and-nose covering is formed with air spaces in its interior. It consists in particular of a knit micromesh material consisting of polyamide, polyester or polylactic acid.

IPC Classes  ?

• A41D 13/11 - Protective face masks, e.g. for surgical use, or for use in foul atmospheres
• B01D 39/08 - Filter cloth, i.e. woven, knitted or interlaced material
• B01D 39/16 - Other self-supporting filtering material of organic material, e.g. synthetic fibres
• A62B 23/02 - Filters for breathing-protection purposes for respirators

Abstract

The invention relates to a method for producing hoods in the form of hair nets having meshes, creating hoods having a first dimension over the head from front to rear and a second dimension crosswise thereto. A strand (20) of a net having a mesh (23) is created from threads (21). The strand (20) has two longitudinal sides. The number of meshes (23) of the set crosswise to the longitudinal sides corresponds to the number of meshes (11) of the hair net to be produced along the first or second dimension of the hair net. On or neighboring the two longitudinal sides of the strand (20), one elastic thread (22) each is fed into the other meshes (23) of the net. At specified, regular distances, the two elastic threads (22) are guided together and connected to one another. The distance is chosen such that the number of meshes (23) of the net between two connection points (24) in the longitudinal direction of the strand (20) corresponds to the number of meshes (11) of the hair net to be produced along the first or second dimension of the hair net. The two elastic threads (22) are connected by joining to one another by means of a sealing and/or melting process. A weakness (25) is introduced in the connection region (24).

A strand (20) of a net having a mesh (23) is created from threads (21). The strand (20) has two longitudinal sides.

On or neighboring the two longitudinal sides of the strand (20), one elastic thread (22) each is fed into the outer meshes (23) of the net. At specified, regular distances, the two elastic threads (22) are guided together and connected to one another. The distance is chosen such that the number of meshes (23) of the net between two connection points (24) in the longitudinal direction of the strand (20) corresponds to the number of meshes (11) of the hair net to be produced along the first or second dimension of the hair net.
