    • A papermakers fabric having a system of flat monofilament yarns which are woven with relatively long floats on at least one side of the fabric. In the preferred embodiment, the flat yarns are oriented in the machine direction of the papermakers fabric and are interwoven with at least a top layer of round cross machine direction yarns such that in each repeat, the flat yarns float over more top layer cross machine direction yarns than the number of top layer yarns which the flat yarns weave under. In the preferred embodiment, pairs of vertically stacked flat monofilament yarns are woven in the machine direction such that the upper flat yarns define relatively long floats on the top surface of the fabric and the lower flat yarns define floats on the bottom surface of the fabric.
    • 一种造纸织物,其具有在织物的至少一侧上以较长的浮子编织的扁平单丝纱系统。 在优选实施例中,扁平纱线在造纸织物的机器方向上取向,并且与至少一个圆形横向机器方向纱线的顶层相互交织,使得在每个重复中,扁平纱线在更上层的跨机器方向上漂浮 纱线比平纱在下面编织的顶层纱线数量多。 在优选实施例中,垂直堆叠的扁平单丝纱线在机器方向上被编织,使得上部平面纱线在织物的顶部表面上限定相对较长的浮子,并且下部平面纱线限定织物底部表面上的漂浮物。

    • The present invention is directed to a papermakers fabric which provides for usage of high aspect ratio yarns as structured weave components. The fabric comprises a system of flat monofilament machine direction yarns (hereinafter MD yarns) which are woven in a selected weave construction which provides stability to the fabric. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. The lower MD yarns may weave in an inverted image of the upper MD yarns to provide floats on the bottom fabric surface or may weave with a different repeat to provide a different surface on the bottom of the fabric.At least the upper MD yarns are flat monofilament yarns woven contiguous with each other to reduce the permeability of the fabric and to lock in the machine direction alignment of the stacking pairs of MD yarns. In the preferred embodiment, the same type and size yarns are used throughout the machine direction yarn system and both the top and the bottom MD yarns weave contiguously with adjacent top and bottom MD yarns, respectively. The stacked, contiguous woven machine direction system provides stability and permits the MD yarns to have a relatively high aspect ratio, cross-sectional width to height, of greater than 3:1.
    • 本发明涉及一种造纸织物,其提供使用高纵横比纱线作为结构织物组分。 该织物包括以选择的织造结构编织的扁平单丝机器方向纱线(以下称为MD纱线)的系统,其为织物提供稳定性。 在优选实施例中,MD纱线系统包括垂直堆叠的上下纱线。 优选地,上MD纱线在织物的上表面上限定漂浮物,并且每个上MD纱线以垂直堆叠的方向与较低的MD纱线成对配对。 下MD纱线可以以上MD纱线的倒置图像编织,以在底部织物表面上提供浮子,或者可以用不同的重复编织,以在织物的底部提供不同的表面。 至少上层MD纱线是彼此连续织造的扁平单丝纱线,以减少织物的渗透性并锁定MD纱线堆叠对的机器方向对齐。 在优选实施例中,在机器方向纱线系统中使用相同类型和尺寸的纱线,并且顶部和底部MD纱线分别与相邻的顶部和底部MD纱线连续地编织。 层叠的连续织造机方向系统提供稳定性并且允许MD纱线具有大于3:1的相对高的纵横比(横截面宽度与高度)。

    • A flat woven pin-seamed papermakers fabric wherein machine direction yarns define a series of orthogonal seaming loops on the opposing fabric ends. The fabric comprises a system of flat monofilament machine direction warp yarns (hereinafter MD yarns) which are woven in a selected weave construction. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. End segments of the lower MD yarns are removed and the upper MD yarn ends are looped back upon themselves and rewoven into the fabric end in the space vacated by the trimmed lower MD yarn end segments. Non-loop forming upper MD yarns are also preferably backwoven into the space vacated by trimming the respective lower MD yarns. Preferably, at least the upper MD yarns are woven contiguous with each other to lock in the machine direction alignment of the stacking pairs of MD yarns and the orthogonal orientation of the end loops. The seaming loops of the opposing ends are intermeshed and joined via a pintle yarn. The permeability of the seam area is controlled via the inserting of rectangular stuffer yarns parallel to the pintle yarn.
    • 平面编织针缝制造纸织物,其中机器方向纱线在相对的织物端部限定一系列正交的接缝环。 织物包括以选定的编织结构编织的扁平单丝机器方向经纱(以下称为MD纱线)的系统。 在优选实施例中,MD纱线系统包括垂直堆叠的上下纱线。 下部MD纱线的末端部分被去除,并且上部MD纱线末端环绕在自身上并且在被修剪的下部MD纱线端部部分腾空的空间中重新编织到织物端部中。 非环形上MD纱也优选地通过修剪相应的下MD纱线而退回到空出的空间中。 优选地,至少上层MD纱线相互编织连接以锁定MD纱线的堆叠对和端环的正交取向的机器方向对齐。 相对端的接缝环经过枢轴纱相互啮合并连接。 通过插入平行于双针纱的矩形填充纱线来控制接缝面积的渗透性。
