Abstract
In a multilayer fabric for nonwoven fabric, an upper-surface-side fabric formed from upper-surface-side warps (Ub,U,U,U,U',Ub,U,U,U,U′) and upper-surface-side wefts (′U,′U,′U,′U) and a lower-surface-side fabric formed from lower-surface-side warps (Lb,L,L,Lb,L,L) and lower-surface-side wefts (′L,′L,′L,′L) are bound together. First warps (Ub,Ub) of the upper-surface-side warps serve as first binding yarns that bind the upper-surface-side fabric and the lower-surface-side fabric, and second warps (Lb,Lb) of the lower-surface-side warps serve as second binding yarns that bind the upper-surface-side fabric and the lower-surface-side fabric. A high-friction yarn is used as at least some of the upper-surface-side warps.
