Brushed circular knitted fabric

A brushed circular knitted fabric comprising double loops formed from at least two kinds of synthetic fiber multifilaments including a synthetic fiber multifilament A laid on a synthetic fiber multifilament B, wherein 1) an inside portion of the double loops comprises a synthetic fiber multifilament A having a boiling water shrinkage of 12 to 30% and an outside portion comprises a synthetic fiber multifilament B having a boiling water shrinkage of less than 12%, 2) at least one surface of said circular knitted fabric has undergone heating that shrinks the synthetic fiber multifilaments A and B and then brush processing, 3) an index represented by equation (FT index) is 2.1 or greater, and 4) a stitch length of said synthetic fiber multifilament A is shorter than a stitch length of said synthetic fiber multifilament B by 20% or more:

• FT index=T2/T1
• T1:
• thickness (of one fabric layer) according to JIS L 1096 8.4 method A
• T2:
• thickness of a folded part of the circular knitted fabric in a state where the circular knitted fabric is folded in two according to the same method prescribed by the above-described JIS.
