Abstract

A double raschel knitted fabric is disclosed which is excellent in a strength although openings are formed. A double raschel knitted fabric is provided including outer/lining textures and a joining portion that connects them to each other, in which the outer texture has openings, and a total overlapping fineness of sinker loops in the lining texture, which is calculated by the following calculation formula, is 400 dtex to 1800 dtex. The total overlapping fineness of sinker loops (dtex)−Σ K−1 n (The fineness of a ground yarn fed from a k th guide bar (dtex))   [Eq. 1] (The number of underlaps of the ground yarn fed from the k th guide bar) (The threading ratio of the k th guide bar)

1 . A double raschel knitted fabric comprising an outer texture, a lining texture, and a joining portion connecting the outer texture and the lining texture, wherein the outer texture has openings, and a total overlapping fineness of sinker loops in the lining texture is 400 dtex to 1800 dtex, calculated by a calculation formula:

         5 . The double raschel knitted fabric according to  claim 1 , wherein the lining texture is composed of a plurality of knit textures, and at least one of the corresponding knit textures is a cord knit texture. 
     
     
         6 . The double raschel knitted fabric according to  claim 5 , wherein the lining texture has a combination of the cord knit texture and one or more of a denbigh knit texture and a chain knit texture. 
     
     
         7 . The double raschel knitted fabric according to  claim 5 , wherein the cord knit texture that forms the lining texture is made with 2- to 8-needle swings. 
     
     
         8 . The double raschel knitted fabric according to  claim 6 , wherein needle loops of the cord knit texture that forms the lining texture, and needle loops of the denbigh knit texture and/or the chain knit texture that form(s) the lining texture overlap in different directions to form the needle loops. 
     
     
         9 . The double raschel knitted fabric according to  claim 6 , wherein the cord knit texture and the denbigh knit texture that form the lining texture form sinker loops through underlapping in a same direction. 
     
     
         10 . The double raschel knitted fabric according to  claim 6 , wherein needle loops formed b′ the cord knit texture that forms the lining texture are closed-stitches. 
     
     
         11 . The double raschel knitted fabric according to  claim 6 , wherein needle loops formed by the denbigh knit texture and/or the chain knit texture that form(s) the lining texture are opened-stitches. 
     
     
         12 . The double raschel knitted fabric according to  claim 1 , wherein a burst strength is 1800 Pa to 3800 Pa. 
     
     
         13 . The double raschel knitted fabric according to  claim 1 , wherein a seam fatigue is 2.5 mm or less.
