Abstract: In a multilayer fabric for nonwoven fabric 30, an upper-surface-side fabric formed from upper-surface-side warps (1Ub, 2U, 3U, 4U, 4U′, 5Ub, 6U, 7U, 8U, 8U′) and upper-surface-side wefts (1′U, 2′U, 3′U, 4′U) and a lower-surface-side fabric formed from lower-surface-side warps (1Lb, 2L, 3L, 5Lb, 6L, 7L) and lower-surface-side wefts (1′L, 2′L, 3′L, 4′L) are bound together. First warps (1Ub, 5Ub) 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 (1Lb, 5Lb) 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.

Abstract: According to the present invention, the curling or lifting of webs that occurs during the production nonwoven fabrics, and wrinkles that form on the surface of nonwoven fabrics are prevented. Also, the webs can be easily taken off without making grip stronger than necessary. The present invention pertains to an industrial fabric formed by weaving warp and weft, wherein an embossed pattern having a concavo-convex shape is formed in the vicinity of the apex of a knuckle portion exposed on the surface side of the warp and/or weft. In particular, the industrial fabric is characterized in that the warp and/or weft having the embossed pattern are plastic monofilaments.
