Abstract

The invention relates to a seamless knitted leak-proof mask. The edge of the mask is divided into rib stitch, purl stitch or laying-in stitch; the included angle between the stitch wale of the rib stitch or laying-in stitch and the edge of the seamless knitted leak-proof mask is 90+ / -5 degrees, and the included angle between the stitch wale of the purl stitch and the edge of the seamless knitted leak-proof mask is 0+ / -5 degrees; the edge contains high elastic yarn, the content of the high elastic yarn is larger than or equal to 50wt%, the elastic recovery rate of the high elastic yarn is larger than or equal to 40% when the constant elongation of the high elastic yarn is 5%, and the width of the edge is 5-20 mm; the rib stitch is 1+1 rib or 2+1 rib or 2+2 rib or 3+2 rib or 3+3 rib. The seamless knitted leak-proof mask has the advantages that the edge can be deformed according to the movement of the face, so that the edge of the mask can always fit the face of the human body under all circumstances, thereby improving the airtightness of the mask.

Description

technical field [0001] The invention belongs to the technical field of masks and relates to a seamless knitted air-leakage-proof mask. Background technique [0002] 3D three-dimensional filter masks are currently the most popular anti-haze masks on the market. They can be divided into three categories according to the wearing style: ear-worn, head-worn and neck-worn. Among them, the ear-worn type is prone to ear discomfort due to concentrated stress, while the head-worn type and neck-worn type are evenly stressed and are more suitable for long-term wear. [0003] There are two main factors that affect the protective effect of masks. One is the filtration efficiency of the mask filter material for particulate matter, and the other is the suitability of the mask and the wearer, that is, the sealing performance between the edge of the mask and the face of the wearer. In terms of filter materials, good filtration efficiency has been achieved at present, such as N95 and N99 mask...
