摘要： The present invention relates generally to papermaking, and relates more specifically to fabrics employed in making press felts on a paper machine, pulp machine fiber cement belts, and corrugated paper board, or box-board. The invention also relates to the monofilament base of fabric optionally with a needled batt which can provide one or more of the following advantages: hydrolysis resistant materials, providing light weight high strength fabrics, having a high permeability, and soft surface with a high coefficient of friction. The present invention also relates to an integrated loop seam integrated with machine direction yarns of the monofilament base which can provide one or more of the following advantages: extremely stable and flexible corrugator fabric, and the ability to provide a non-marking loop seam.

摘要： A sheet of fibrous web material having one textile-like surface and an opposite substantially smooth surface, a grain depth memory factor greater than 80, an apparent density in the range of about 4 to about 7 pound ream/caliper point in mils, a caliper (at a basis weight between about 50 and about 75 pounds/3000 square feet) greater than 0.008 inch, and a machine-direction sheet stretch of at least 5%. The invention includes a method of manufacturing the sheet comprising partially dewatering a wet fibrous web to about 30% to about 60% solids, conveying the web to a compression nip defined by a smooth-surfaced roll and a textured-surfaced fabric material, moving the fabric material at a speed of about 15% to about 35% less than the surface speed of the smooth-surfaced roll, compressing the web in the nip with a compression force between about 5 pounds/linear inch and about 100 pounds/linear inch, with an average pressure of between about 20 pounds per square inch and about 400 pounds per square inch in the compression nip, subjecting the fabric material to a tension on opposite sides of the compression nip with the tension on the fabric material entering the nip being greater than the tension on the fabric material exiting the nip, and drying the web.
摘要翻译：具有一个织物状表面和相对的基本上平滑的表面的纤维网状材料片，大于80的晶粒深度记忆因子，约4至约7磅范围内的表观密度，以米尔计，卡尺（约50至约75磅/ 3000平方英尺之间的基重）大于0.008英寸，机器方向片材伸长率至少为5％。本发明包括制造片材的方法，其包括将湿纤维网部分地脱水至约30％至约60％的固体，将幅材输送到由光滑表面辊和纹理表面的织物材料限定的压缩间隙，织物材料以比光滑表面辊的表面速度小约15％至约35％的速度，以约5磅/英寸至约100磅/英寸的压缩力在辊隙中压缩幅材，在压缩压区中平均压力为约20磅/平方英寸和约400磅/平方英寸，使织物材料在压缩辊隙的相对侧上受到张力，进入辊隙的织物材料上的张力更大比织物离开辊隙的张力和干燥纤维网。
