Abstract
An industrial two-layer fabric has an inner space between an upper side fabric and a lower side fabric. Some or all of upper side wefts or lower side wefts are secondary wefts interwoven with upper side warps or lower side warps so as to make the number of warps passing on an upper surface of the upper side fabric or passing on a lower surface of the lower side fabric larger than that on an inner space side of the upper or lower side fabric and a long crimp in the inner space is formed by the secondary weft.
