Abstract
An industrial fabric is a web woven from warp yarns made of monofilaments and weft yarns made of monofilaments. The warp yarns are of a double-layer structure. One of warp yarn basic units comprises four sub-units, two sub-units being located on an upper layer, the other two sub-units being located on a lower layer. The warp yarns on the upper layer and the warp yarns on the lower layer are vertically overlapped, wherein at least two sub-units comprise two parallel narrow warp yarns. Upper warp yarns and lower warp yarns are identical in texture structure, or one surface is identical to the other surface after rotating by 180 degrees. The industrial fabric is stable in structure and good in overall consistency. The upper surface is good in flatness, the surface is free from defects, and the quality and intensity of the fabric are improved.
