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.
Claims8
An industrial fabric used in a process of manufacturing a non-woven fabric comprising:
- warps and wefts woven with each other, wherein:
- all embossed knuckles of the warps comprises an emboss concave pattern only at or near an apex of the knuckle whereby reducing floating of the non-woven fabric during a manufacturing of the non-woven fabric,
- wherein a cutting depth of said emboss concave pattern is formed between 4%˜ 23% of a diameter of said warps, and
- wherein some of the warps, some of the wefts, or some of the warps and the wefts are made of carbon yarns.
