    摘要： A papermakers forming fabric having two layers of CMD yarns interwoven with a system of MD yarns to form a multilayer fabric. The paper support surface CMD yarn layer has at least three times as many CMD yarns as the machine contact surface CMD yarn layer. The higher count of upper layer CMD yarns provides an improved paper forming/carrying surface with improved drainage characteristics.

    摘要： A double layer papermaking fabric having twice as many paper side cross machine direction yarns as machine side cross machine direction layer. A system of machine direction yarns is interwoven with both cross machine direction layers, with each machine direction yarn forming first and second knuckles on each side of the fabric. The paper side knuckles are woven with uniform spacing and each machine side cross machine direction yarn is passed under by two machine direction knuckles spaced by at least one intermediate machine direction yarn.

    摘要： A two-ply forming fabric having an upper paper carrying/forming layer which comprises twice as many cross machine direction yarns as the lower, machine-side layer. A system of machine direction yarns interweaves in a selected repeat pattern such that a zigzag effect is produced on the underside of the fabric by the machine direction yarns to provide improved drainage. The higher count of upper layer CMD yarns selectively interwoven in a non-twill pattern with 80%-100% cover of MD yarns provides an improved paper forming/carrying surface.

    摘要翻译： 一种双层成形织物，其具有上部纸张承载/成形层，其包含与下部机器侧层的横向机器方向纱线的两倍。 机器方向纱线的系统以选定的重复图案交织，使得机织方向纱线在织物的下侧上产生锯齿形效应，以提供改进的排水。 上层CMD纱线的数量越多，选择性地以非斜纹图案交织，具有80％-100％的MD纱线覆盖，提供了改进的造纸/承载表面。
