摘要： A single layer papermakers fabric comprises machine direction (MD) warp yarns interwoven with cross-machine direction (CD) weft yarns to a repeating weave pattern requiring N sheds in the loom, N being an integer and at least 4. Each warp yam follows a path, in the paper side surface comprising four segments in each pattern repeat. In each of the first and third segments, the warp yarn interweaves with three consecutive weft yams to form a double warp knuckle, and in the second and fourth, segments, the warp yarn forms respectively a first and second MD float having unequal float lengths, at least one of the MD floats being over at least N consecutive weft yarns. The fabrics provide high air permeability, and increased surface contact area, stability and seam strength, and are particularly suitable for use as forming fabrics and through air dryer fabrics for tissue and towel products.

摘要： A multilayered papermakers1 forming fabric (1) comprises at least one set of machine direction (MD) warp yams (100,110), at least a first set of cross-machine direction (CD) machine side layer weft yams (120); and paper side layer weft yams (200,220) woven in a repeating pattern with at least some of the MD warp yams (100,110). At least some of the paper side layer weft yarns (200, 220) comprise an array of bulk enhancing weft yarns (220) each having a vertical dimension which exceeds a corresponding vertical dimension of each of the remaining paper side layer weft yams (200) in a ratio of at least 1.25:1. Selected weft yarns can have different float lengths in the paper side surface. The fabrics of the invention impart increased bulk for products such as towel or tissue without loss of other required characteristics.

摘要： A double layer papermakers' fabric that is particularly suitable for forming or through-air drying (TAD) of high bulk tissue and towel product is provided. The fabric includes a single warp yarn system interwoven with three weft yarn systems such that: a first of the weft yarn systems is located on the paper side (PS) surface of the fabric; a second of the weft yarn systems is located on the machine side (MS) surface of the fabric; and the third weft yarn system is located intermediate between the first and second weft yarn systems. The yarns of the first and second weft yarn systems are interwoven with the warp yarn system such that they are vertically stacked with respect to one another in the fabric. The yarns of the third weft yarn system are interwoven so as to be located in a central plane of the fabric that is intermediate of the first and second weft yarn systems, and each yarn of the third yarn system is located in between the vertically stacked pairs of weft yarns of the first and second weft yarn systems. The warp and weft yarn systems are interwoven according to an asymmetric design which provides generally rectangular pockets on each of the PS and MS of the fabric with the yarns of the third weft yarn system forming the "bottom" of each pocket. There may be from about 50 to 750 pockets per sq. in. of fabric, each ranging in depth from about 0.1mm to about 1.0 mm in depth; these pockets impart unevenness to the fabric surface which assists in creating bulk in the sheet formed or conveyed thereon. The fabrics of the invention also offer low sheet contact area, typically less than 30% of the total fabric surface, and generally in the range of from 15% to about 20%. The fabrics are also highly air permeable to ensure good air flow and drainage of the sheet.
摘要翻译：提供了一种双层造纸机织物，其特别适用于高松厚度纸巾和毛巾产品的成形或通风干燥（TAD）。织物包括与三个纬纱系统交织的单一经纱系统，使得：第一纬纱系统位于织物的纸侧（PS）表面上; 第二纬纱系统位于织物的机器侧（MS）表面上; 并且第三纬纱系统位于第一和第二纬纱系统之间的中间。第一和第二纬纱系统的纱线与经纱系统交织，使得它们在织物中相对于彼此垂直堆叠。第三纬纱系统的纱线相互交织以便位于第一和第二纬纱系统中间的织物的中央平面内，并且第三纱线系统的每根纱线位于垂直堆叠的对之间的第一和第二纬纱系统的纬纱。经纱和纬纱系统根据不对称设计交织，该不对称设计在织物的每个PS和MS上提供大致矩形的袋，而第三纬纱系统的纱形成每个袋的“底部”。每平方英寸织物可以有约50至750个袋，每个袋的深度从约0.1mm至约1.0mm的深度; 这些口袋赋予织物表面不均匀性，这有助于在其上形成或传送的片材中产生松厚。本发明的织物还提供低片接触面积，通常小于织物总表面的30％，并且通常在15％至约20％的范围内。织物也具有高透气性以确保良好的空气流动和纸张排水。

摘要： A machine side layer weave design for use in woven composite papermakers forming fabrics. The composite fabric has two sets of we yarns interwoven with at least one system of warp yams. In each repeat of the machine side layer weave design, at least 50% of the warp yarns pass under two adjacent weft yams on the machine side of the fabric to form a double warp knuckle, and each double war knuckle is bounded on either side by a single warp knuckle formed on each of the first and second weft passed under by the double warp knuckle. Further, in each repeat of the weave, each weft yarn is passed under by two adjacent warp yams to form two adjacent single warp knuckles. The knuckles are evenly distributed across the machine side surface. The machine side layer weave design is effective in minimizing or eliminating fabric edge curl.

摘要： A papermaking fabric is treated by applying a nanoparticle coating to improve resistance to contamination in the papermaking system. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating is applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device in the dryer section to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned and then dried. Following controlled application of the coating, excess material is removed, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the dryer section or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.
摘要翻译：通过施加纳米颗粒涂层来处理造纸织物以改善造纸系统中的污染性。涂层在织物制造过程中施加，并在热定型期间固化。或者，通过利用现有的淋浴器或将喷雾臂或其它合适的涂覆施加装置定位在干燥器部分中来涂覆或更新涂层，以将涂层以受控的均匀方式施加到织物上。在施加涂层之前，先将织物彻底清洁然后干燥。在控制施加涂层之后，除去多余的材料，然后通过利用干燥部分的环境热量或便携式加热器组来固化织物上剩余的涂层。以这种方式，织物不必从机器中移除，以便施加或更新耐污染涂层。
