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: The present invention is directed to endless belts and fabrics for use in a process control loop which can be used in the production of the products specified in the specification. The belt is provided with means for emitting electromagnetic radiation upon excitation by an energy source. That is, the belt is provided with a sensor which emits electromagnetic radiation when excited by an energy source, such as an external one that is directed at the belt. A sensor is comprised of an electromagnetic radiation emitting compound dispersed within a matrix. The sensor may also contain a scattering material. The sensor can take the form of a filamentary material, coating or film that can then be incorporated on or in the belt. In operation, energy emitted from an energy source is directed at the belt. Upon excitation of the sensor by the energy, the sensor emits electromagnetic radiation, which is detected by a detector located nearby.

Abstract: The present invention is directed towards paper machine clothings comprised of interconnected bicomponent fibers. In one embodiment of the invention, the paper machine clothing is comprised entirely of bicomponent fibers in both the machine and cross machine direction. Advantage is taken of the unique bicomponent fiber structure, which permits selection of different materials for the sheath and core components. For instance, the sheath material may have a melting point lower than the melting point of the core material. Accordingly, a fused, bonded structure of bicomponent fibers can be formed where the sheath component has a melting point lower than the core component. By heating a fabric constructed of bicomponent fibers to a temperature greater than the melting point of the sheath component and lower than the melting point of the core component, with subsequent cooling of the fabric to below melt temperature of the sheath component, a fused, bonded structure will result.

Abstract: The present invention provides a method of removing contaminants from industrial process fabrics relying upon cryogenic techniques, wherein the fabric is impacted with solid particles of carbon dioxide. A cryoblaster projects the carbon dioxide particles at the fabric. The cryoblaster scans over the entirety of the fabric at a scanning rate particle velocity, and particle flow rate in order to insure that the fabric is cleaned without suffering any damage.

Abstract: Disclosed is a method of producing polysaccharide foams and foams produced by the method. The polysaccharide foams are formed from a wet condition and are convection dried with a flow of warm or hot air. Such foams exhibit improvements over foams dried under ambient conditions. The present invention also discloses the formation of multi-ply foam layers. At least two sheets of foam layers are layered together and laminated either mechanically or chemically to produce a composite structure.

Abstract: The present invention is directed towards fabrics formed from yarns of a composite filament structure. The composite filament structure is a high modulus filament material covered with bicomponent filaments and the entire surface area of the high modulus material should be covered. The fabric can be used in clothings for paper making machines and other industrial uses.

Abstract: A method of producing a polysaccharide foam is provided. The method comprises mechanically foaming an aqueous solution of a soluble polysaccharide and thereafter reacting the foam to produce stable foam. Typically, the soluble polysaccharide is an alginate, hyaluronate, carrageenans, chitosan or starch.
