Mask made of knitted fabric

Abstract

A mask made of knitted fabric includes a knitted cloth and two ear loops. The two ear loops are knitted together with the knitted cloth and are respectively located on two sides of the knitted cloth. The knitted cloth is composed of a double-layer knitted structure and a single-layer knitted structure. The double-layer knitted structure is a basis of the knitted cloth. The single-layer knitted structure defines at least one bending line, the single-layer knitted structure is only connected to one of two surface layer textures to which the double-layer knitted structure belongs, and whether the bending line is a valley fold line or a mountain fold line is determined by connection between the single-layer knitted structure and the double-layer knitted structure.

What is claimed is: 
     
         1 . A mask made of knitted fabric comprising:
 a knitted cloth, composed of a double-layer knitted structure and a single-layer knitted structure, the double-layer knitted structure being a basis of the knitted cloth, the single-layer knitted structure defining at least one bending line for the knitted cloth to fold, the single-layer knitted structure only connected to one of two surface layer textures to which the double-layer knitted structure belonging, and wherein whether the bending line is a valley fold line or a mountain fold line is determined by connection between the single-layer knitted structure and the double-layer knitted structure; and   two ear loops, knitted together with the knitted cloth, and the two ear loops respectively located on two sides of the knitted cloth.   
     
     
         2 . The mask made of knitted fabric as claimed in  claim 1 , wherein the two ear loops are respectively a tubular knitted fabric formed by a sac-like knitting, and the two ear loops are connected to the knitted cloth by an intarsia knitting. 
     
     
         3 . The mask made of knitted fabric as claimed in  claim 2 , wherein the single-layer knitted structure forms the bending lines, the bending lines include a plurality of longitudinal bending lines and a plurality of oblique bending lines connected between any two of the adjacent longitudinal bending lines respectively, the plurality of longitudinal bending lines are arranged at intervals, and each of the oblique bending lines intersects with one of the other oblique bending lines on one of the longitudinal bending lines. 
     
     
         4 . The mask made of knitted fabric as claimed in  claim 3 , wherein parts of the plurality of oblique bending lines form a plurality of diamond-shaped patterns on a surface of the knitted cloth, and the diamond-shaped patterns located at a center of the knitted cloth are larger than the remaining diamond-shaped patterns. 
     
     
         5 . The mask made of knitted fabric as claimed in  claim 1 , wherein the knitted cloth includes an antibacterial yarn added by plating on one side of the double-layer knitted structure. 
     
     
         6 . The mask made of knitted fabric as claimed in  claim 5 , wherein the antibacterial yarn is a graphene yarn. 
     
     
         7 . The mask made of knitted fabric as claimed in  claim 6 , wherein two opposite sides of the knitted cloth that are not adjacent to the two ear loops have different shapes. 
     
     
         8 . The mask made of knitted fabric as claimed in  claim 7 , wherein the two ear loops define two imaginary lines respectively connected with the two ear loops and parallel to each other, the two imaginary lines divide the knitted cloth from top to bottom as a first side block, a middle block and a second side block, and where the first side block close to a center line of the knitted cloth and where the second side block close to the center line of the knitted cloth are knitted by a partial knitting. 
     
     
         9 . The mask made of knitted fabric as claimed in  claim 1 , wherein two opposite sides of the knitted cloth that are not adjacent to the two ear loops have different shapes. 
     
     
         10 . The mask made of knitted fabric as claimed in  claim 9 , wherein the two ear loops define two imaginary lines respectively connected with the two ear loops and parallel to each other, the two imaginary lines divide the knitted cloth from top to bottom as a first side block, a middle block and a second side block, and where the first side block close to a center line of the knitted cloth and where the second side block close to the center line of the knitted cloth are knitted by a partial knitting.
