Abstract

The invention provides a three-dimensional mask with a large mouth space and a production method thereof.The mask comprises a pair of mask fabric layers, the mask fabric layers are trapezoidal and are vertically symmetrical, the upper bottom edges of the mask fabric layers are connected in a sealed mode, the adjacent waist edges of the mask fabric layers are connected in a sealed mode, and the lower bottom edges of the mask fabric layers are open; and the two sides of the lower bottom edge of at least one mask fabric layer are connected with elastic belts. The production method of the three-dimensional mask comprises the following steps: the two long-strip-shaped mask fabric layers are laid in the length direction in an up-down laminated mode; ultrasonic welding is conducted on the two long-strip-shaped mask fabric layers, trapezoid bodies arranged in sequence are obtained, and only the upper bottom edge and the two waist edges of each trapezoid body are subjected to ultrasonic welding; the elastic belts are connected to the two sides of the lower bottom edge of each trapezoid body; and cutting is performed along the waist edge of each trapezoid body to obtain a plurality of mask finished products.

Description

technical field

[0001] The invention relates to the technical field of disposable sanitary consumables, in particular to a three-dimensional mask and a production method thereof. Background technique

[0002] Existing three-dimensional mask, it comprises mask body, is located at its two sides and is used for hanging on the user's ear elastic band; Its shortcoming is: during production, need manual symmetrical bending of two elastic bands and transfer to mask body and align them, and then fix the elastic bands on both sides of the mask respectively. This production process takes a long time and requires manual operation, which is time-consuming and labor-intensive, which is not conducive to continuous and rapid production. Simultaneously, mouth space is less, and use comfort is lower; How to provide a kind of mouth mask that reduces production time consumption, is the technical problem to be solved in this field.

Examples

Embodiment 1

[0021] Such as Figures 1 to 4 As shown, the disposable protective mask of the present embodiment comprises: mask fabric layer 1, and mask fabric layer 1 is trapezoidal and comprises a pair of upper and lower symmetry, and the upper bottom edge 1-1 of this pair of mask fabric layer 1 is closed and connected to each other, and the mask fabric layer 1 is connected to each other. The adjacent waist edges 1-2 of the mask fabric layer 1 are closed and connected to each other, and the lower bottom edge is open; the lower bottom edge sides of at least one mask fabric layer 1 are connected with elastic bands 2 . A flexible metal strip (not shown in the figure) is provided on the edge of the lower bottom edge, which is used to be arranged between the mouth and nose, and is bent so that the mask fits between the mouth and nose.

[0022] The elastic belt 2 includes: a pair of laminated non-woven fabrics, and a plurality of elastic bands or elastic spandex filaments or shrinkable films di...
