Abstract: An industrial fabric such as an endless belt or sleeve for use in the production of nonwovens, and a method of making thereof are disclosed. The industrial fabric is produced by spirally winding strips of polymeric material, such as an industrial strapping or ribbon material, and joining the adjoining sides of the strips of material using ultrasonic welding or laser welding techniques. The fabric may then be perforated using a suitable technique to make it permeable to air and/or water.

Abstract: The invention disclosed herein relates to the use of laser energy to weld or melt selected locations in papermachine clothing (“PMC”) and other industrial and engineered fabrics. The invention also relates to an improved seam for a papermaker or other industrial fabric that has properties such as strength, durability, openness, adequate number of support points, and fiber support index (FSI) essentially the same as the fabric body. The invention also relates to a fabric having a durable seam, wherein the seam width as measured in the MD is a fraction of the width of a normal seam or a seam that is formed using a conventional technique of equal strength.

Abstract: An on-machine-seamable industrial belt and method of forming an on-machine-seamable industrial belt including the steps of providing a base structure having first and second edges, providing a seam connecting the first and second edges, and laminating a layer onto the base structure and the seam.

Abstract: The present invention provides a multilayer multiaxial woven fabric for a papermachine having a reduced interference pattern and accordingly improved dewatering uniformity. The present invention also provides a method of forming such multilayer multiaxial fabric.

Abstract: A nonwoven fabric includes a plurality of through voids, where each of the voids has a first opening associated with a top surface of the fabric and a first raised edge circumferentially adjacent to the first opening. The voids may each further include a second opening associated with a bottom surface of the fabric and a second raised edge circumferentially adjacent to the second opening, such that the first opening may have a surface area that is larger than or the same as the second opening.

Abstract: A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics is disclosed. The structure includes one or more layers of an elastic nonwoven extruded film or sheet, which is elastic, resilient, and compressible in a thickness direction, and extensible, bendable, and resilient in its length and transverse directions, and one or more layers of a plurality of substantially parallel machine direction (MD) yarns in various patterns. The structure can also include one or more layers of a plurality of substantially parallel cross-machine direction (CD) yarns attached on top of or under the MD yarns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.

Abstract: A method for preparing a polyester nanocomposite is presented. The method comprises coating nanoparticles with a dicarboxylic acid. Combining the dicarboxylic acid coated nanoparticles with a coupling agent resulting in a first mixture. Then combining the first mixture with a polyester to form a polyester nanocomposite. The resulting polyester nanocomposite has among other properties a glass transition temperature greater than the polyester itself and also a crystallization temperature less than the polyester itself.

Abstract: In an apparatus for the production of a non-woven web, structure, or article using a spun-bonding process in combination with a forming fabric which is woven having flat CMD yarns, flat MD yarns or both with some or all of such yarns being conductive so as to dissipate static electricity.

Abstract: Disclosed are lagging materials for use on a driven cylindrical pulley or drum for an industrial machine. A lagging material can comprise a seaming element along the cross-machine direction (CD) of each of the opposing ends of the lagging material for forming a seam for seaming opposing ends of a lagging material when brought together. A lagging material can also comprise coatings that increase the Coefficient of Friction of a lagging material when the lagging material is installed onto the drum such that no additional adhesive is required to keep the lagging on the drum circumference when in operation. Also described is an apparatus for installing an on machine seamable lagging including at least two opposed elongate members, such that when the elongate members are drawn together, the lagging material is stretched into a seamable position to be installed on the drum.

Abstract: A structuring layer of a structuring belt for structuring a wet fibrous web in a press section of a tissue papermaking machine for manufacturing high bulk tissue paper, the structuring layer having a web-carrying side with a surface for cooperating with the fibrous web, the surface having depressions distributed over the web-carrying side and forming a three-dimensional structure of the surface. The depressions altogether constitute 20-80% of the surface. Each depression has a dimension l of 0.25-2.5 mm in a first direction in the plane of the top surface area, a dimension b of 0.25-2.0 mm in a second direction in the plane of the top surface area, such directions being at right angles to each other, a mean depth d of 0.05-0.6 mm, and an area a as measured in the plane of the top surface area of 0.063-5.0 mm2.

Abstract: A clothing for supporting a wet paper web for dewatering is provided, comprising a dewatering fabric extending in a machine direction and formed only from a woven material to have a single, substantially consistent, permeability. A pair of laterally-spaced strip portions extend along the dewatering fabric in the machine direction, with each being substantially and consistently impermeable to air and forming a substantially and consistently smooth non-water-retaining surface. The strip portions define a permeable web-carrying portion of the dewatering fabric therebetween, wherein the paper web carried thereby extends over the entire width thereof. The permeable web-carrying portion allows air to flow therethrough, exclusively of the impermeable strip portions, such that the wet paper web carried only by the permeable web-carrying portion is dewatered. The width of the permeable web-carrying portion thereby defines the width of the wet paper web dried thereon. Associated systems and methods are also provided.
