Abstract: A method for manufacturing a papermaker's or industrial fabric requires the application of a polymeric resin material onto preselected locations on a base substrate using an array which deposits the polymeric resin material in droplets having an average diameter of 10? (10 microns) or more. The preselected locations, for example, may be knuckles formed by the interweaving of the yarns making up the fabric or interstices between the yarns. The purpose of such precise application of the resin is to control functional properties of the fabric, such as permeability and abrasion resistance. The polymeric resin material is set by means appropriate to its composition, and, optionally, may be abraded to provide the polymeric resin material above the surface plane of the base substrate with a uniform thickness.

Abstract: A method of manufacturing an industrial fabric comprising the steps of knitting a first fabric strip portion having two widthwise edges and a width that is narrower than the industrial fabric to the desired length of the industrial fabric, forming the first fabric strip portion into an endless loop by joining the widthwise edges with a CD seam, placing the first fabric strip portion around two rotatably mounted rolls and knitting a second fabric portion to the desired length of the industrial fabric, where knitting of the second fabric portion proceeds along the first edge of the first fabric portion and is a knitted continuation thereof. Alternatively, knitted fabric strips can be joined together in a spiral fashion to create a full width industrial fabric.

Abstract: A method for manufacturing resin-impregnated endless belt structures and belt structures designed for use on a long nip press on a papermaking machine and for other papermaking and paper processing applications, requires the application of a sacrificial material onto a base substrate in a predetermined pattern in droplets having an average diameter of 10? (10 microns) or more. Polymeric resin material is then deposited on the base substrate to cover all areas except those on which the sacrificial material has been previously applied. The polymeric resin material is then set by means appropriate to its composition, and the sacrificial material removed. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.

Abstract: A method for manufacturing a belt and a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, requires the application of a sacrificial material onto a base substrate in a predetermined pattern which is to be imparted onto products manufactured with the belt. The sacrificial material is deposited in droplets in a controlled manner so as to control the x, y, z dimension of the material deposited and preferably has having an average diameter of 10? (10 microns) or more. A polymeric resin material is then deposited on the base substrate in all areas except those on which the sacrificial material has previously been applied. The polymeric resin material is then set by means appropriate to its composition, and the sacrificial material removed. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.

Abstract: The present invention is a method for making a roll cover and a roll cover, wherein at least one material is applied to the surface of the roll or a base substrate. In a first embodiment, a single material is applied as a flowable phase. A uniform coating of the material is applied to the roll, and upon setting of the material, such as by cooling, curing, or other means, a smooth and permanent roll cover is formed upon the surface of the roll. In another embodiment, at least two materials are applied in flowable phases to the surface of the roll. The first material may be a sacrificial, removable first material, applied to the surface of the roll cover in a preselected pattern. After the sacrificial material has been applied, a second material, such as a functional resin, is applied to the surface of the roll cover with the sacrificial material removed after the second material has set. In another embodiment, the use of sacrificial material is avoided and the material is applied in a predetermined pattern.

Abstract: A method of manufacturing and a papermaker's or industrial fabric, such as a dryer fabric for the dryer section of a paper machine, includes the application of a polymeric resin material onto preselected locations on the backside of a base substrate using a piezojet array which deposits the polymeric resin material in droplets having an average diameter of 10? (10 microns) or more to build up discrete, discontinuous deposits of the polymeric resin material having a height of about 0.5 mm at the preselected locations. The preselected locations may be the knuckles formed by the interweaving of the yarns making up the fabric. The purpose of the deposits is to separate the backside of the dryer fabric from a surface, such as that of a dryer cylinder or turning roll, to enable air trapped between the dryer fabric and the surface to escape in lengthwise and crosswise directions parallel to the surface, instead of being forced through the fabric, possibly causing “drop off”.

Abstract: A coating for a gas diffusion layer (GDL) of a fuel cell or battery. The coating comprises a dispersion of carbon black, a fluoropolymer, and one of graphite and carbon particulates, in which the size of the particulates are substantially larger than the size of the particles of carbon black and provide structural integrity to the coating so as to minimize cracking thereof. The size of the particles of carbon black may lie within the range of approximately 13-95 nm. The carbon particulates may be chopped carbon fibers, carbon or graphite flakes or platelets, carbon nanotubes, carbon fibrils, or carbon whiskers. The carbon particulates may have a high length to diameter ratio.
