Antimicrobial multilayer knit fabric having air layer, and manufacturing method therefor

Abstract

The present invention relates to a multilayer knit fabric and a manufacturing method for the same and, more particularly, to an antimicrobial multilayer knit fabric having an air layer and a manufacturing method for the same. The multilayer knit fabric of the present invention comprises an upper knit fabric, a lower knit fabric, and a vertical knit fabric including a monofilament yarn, where the upper and lower knit fabrics are spaced apart from each other by the vertical knit fabric to form an air layer inside.

1 . A multilayer knit fabric comprising an upper knit fabric; a lower knit fabric; and a vertical knit fabric comprising a monofilament yarn, wherein the upper and lower knit fabrics are spaced apart from each other by the vertical knit fabric to form an air layer inside. 
     
     
         2 . The multilayer knit fabric according to  claim 1 , wherein the multilayer knit fabric is an antimicrobial knit fabric. 
     
     
         3 . The multilayer knit fabric according to  claim 1 , wherein the upper knit fabric is a non-antimicrobial knit fabric. 
     
     
         4 . The multilayer knit fabric according to  claim 1 , wherein the upper knit fabric is a yarn dyed knit fabric. 
     
     
         5 . The multilayer knit fabric according to  claim 1 , wherein the upper knit fabric comprises at least one fiber selected from the group consisting of polyester, nylon, and spandex, the fiber being a 20-50 D fiber. 
     
     
         6 . The multilayer knit fabric according to  claim 1 , wherein the lower knit fabric is an antimicrobial knit fabric. 
     
     
         7 . The multilayer knit fabric according to  claim 1 , wherein the lower knit fabric is an antimicrobial and electrically conductive knit fabric. 
     
     
         8 . The multilayer knit fabric according to  claim 1 , wherein the lower knit fabric is made by knitting using a fiber containing a copper component and a fiber not containing a copper component. 
     
     
         9 . The multilayer knit fabric according to  claim 8 , wherein the fiber containing a copper component is a conductive fiber having a coating of the copper component on the surface of a nylon fiber. 
     
     
         10 . The multilayer knit fabric according to  claim 1 , wherein the monofilament yarn is at least one selected from the group consisting of a polypropylene monofilament yarn, a nylon monofilament yarn, and a polyester monofilament yarn. 
     
     
         11 . The multilayer knit fabric according to  claim 10 , wherein the monofilament yarn has a thickness of 20-50 D. 
     
     
         12 . The multilayer knit fabric according to  claim 10 , wherein the monofilament yarn is knitted together with a fiber containing a copper component. 
     
     
         13 . The multilayer knit fabric according to  claim 1 , wherein the multilayer knit fabric has the upper and lower knit fabrics spaced at least 1.0 mm apart by the vertical knit fabric. 
     
     
         14 . A method for manufacturing the multilayer knit fabric according to  claim 1 , the method comprising supplying a fiber containing a copper component and a fiber comprising a monofilament yarn to a double-sided circular knitting machine having a 18 to 30 gauge with a loop length of 4 to 20 cm through 80 to 150 feeders. 
     
     
         15 . An antimicrobial or antistatic clothing comprising the multilayer knit fabric according to  claim 1 . 
     
     
         16 . A water-absorbing fabric comprising the multilayer knit fabric according to  claim 1 . 
     
     
         17 . An incontinence pad comprising a water-absorbing fabric comprising the multilayer knit fabric according to  claim 1 .
