Problems solved by technology

This type of 3D mask made of non-woven fabric is hard and does not fit the human face; and the nose is equipped with a nose clip, which is generally made of steel wire. If used for a long time, the nose will cause pain
The masks produced by 3D printing technology are made of plastic, rubber, resin and other materials. The materials are relatively hard and airtight. Long-term wearing is prone to pain and stuffiness.

[0042] Embodiment 2: A kind of method for preparing knitted fully formed 3D mask

[0043] Such as Figure 5 As shown, it is a schematic diagram of knitting on the machine of the knitted fully formed 3D mask, 1 is the right ear strap, 2 is the right ear strap, 3 is the right ear strap, 4 is the tuck connection on the right ear side, 5 is The lower half of the back piece of the mask body, 6 is the lower half of the front piece, 7 is the upper half of the front piece, 8 is the upper half of the back piece, 9 is the tuck joint on the left ear side, and 10 is the left The ear band, 11 is the left ear band, and l2 is the left ear ear band. When knitting, start by knitting the earbands behind the ears first, then weave the air layer, knit once on the front bed and once on the back bed, do eight sets of cycles, and then form the earbands behind the ears through flat narrowing stitches; then through left narrowing stitches Weave the back strap of the right ear strap by adding stitche...

Embodiment 3

[0048] Embodiment 3: A kind of N95 mouth mask

[0049] Add multi-layer melt-blown non-woven fabric filter element to the knitted fully formed 3D mask prepared in Example 2, the fabric material can be selected from polypropylene, polyolefin, polyester and polyamide, etc., through the respiratory protective mask of GB2626-2019 and other indicators According to the test, the filtration efficiency can reach 98%, which meets the N95 standard.

Abstract

The invention provides a knitted fully formed 3D mask, which belongs to the technical field of textiles. The knitted fully formed 3D mask of the present invention is woven in an integrated manner, which saves post-processing time and improves weaving efficiency; the opening design under the mask body can facilitate the replacement of filter materials and can be used multiple times. Good environmental protection effect; the nose depends on the softness of the knitted fabric itself to fit the nose, combined with the design of different lengths of the ear straps, making the mask fit the human face more closely; the mask body is based on the human body's nose bridge, mouth The neck and chin are designed with a certain angle of curve, and the connecting part is also designed with an angle according to the cheekbones and jawline of the human body to make it more ergonomic. aesthetics.

Description

technical field [0001] The invention relates to a knitted fully formed 3D mask, which belongs to the technical field of textiles. Background technique [0002] Masks are hygienic products that people often use in daily life. They are generally worn on the nose and mouth to filter dust, germs and other foreign objects in the air, as well as harmful gases and droplets, etc., to prevent them from entering the respiratory organs and affecting their health; Especially in severe smog areas, masks have become people's first choice of protective equipment. [0003] At present, the commonly used mask structure in the market includes the mask body and the laces on both sides. The production of this type of mask needs to be sewn in the later stage, that is, several layers of textiles are cut first and then made into the mask body to make it look like a bag. Then sew the straps on the mask body. The operation steps of this method are cumbersome, time-consuming and labor-intensive, the ...
