Abstract: A wet paper web transfer belt (1) has a wet paper web-side layer (31), including a hydrophilic fibrous body (30), and a machine-side layer (32). A base fabric (33) disposed in the belt comprises a first woven fabric (34), disposed on a wet paper web (W) side, and a second woven fabric (35) disposed on a press roll (10) side, and the first woven fabric (34) and the second woven fabric (35) are stacked together. A portion of the hydrophilic fibrous body (30) is exposed on a surface (37) of the wet paper web-side layer (31). The first woven fabric (34) and the second woven fabric (35) include weft yarns (36) made of a material of low water absorptivity. When the hydrophilic fibrous body (30) is formed in the wet paper web-side layer (31) of the belt (1) by needle punching, an increase in the widthwise dimension of the belt due to the absorption of water by the hydrophilic fibrous body (30) is reduced.

Abstract: An allergen trap is provided. The allergen trap includes a woven or nonwoven substrate having at least one strata. The trap is impregnated with or otherwise treated with a tacky adhesive by which allergens may be trapped. An example of an allergen is a dust mite. The tacky adhesive, in turn, may be treated with a miticide or activated carbon.

Abstract: A press felt for use in the press section of a papermaking machine is provided. The press felt includes a base fabric layer and at least one layer of a staple fiber batt material connected thereto. The press felt has a paper side surface (PS) which when in operation is in contact with a paper web conveyed thereon and a machine side surface (MS) which contacts various press section components. The base fabric layer includes a regenerated cellulosic component in either or both the MD and CD yarns. Regenerated cellulosic fibers may also be provided in the batt and/or scrims located in the batt to improve dewatering when compared to similarly constructed felts which lack this regenerated cellulosic material.

Abstract: A press felt for use in the press section of a papermaking machine is provided. The press felt includes a base fabric layer and at least one layer of a staple fiber batt material connected thereto. The staple fiber batt material is includes between 20% to 100% by weight of a regenerated cellulosic staple fiber material, such as rayon, and from 80% to 0% by weight of a polymeric staple fiber, such as nylon. A scrim including regenerated cellulosic material can also be incorporated into the press felt construction, either between two layers of batt material, or between a batt layer and the base fabric. The regenerated cellulosic staple fibers of the batt and/or scrim having a dtex from at least about 1.1 to about 44, and are preferably non-fibrillatable. As a further option, at least a portion of the base fabric includes a regenerated celluliosic material.

Abstract: A lightweight, flexible, layered insulation composed of glass or ceramic fabric covered with a ceramic coating and overlying an insulating felt made from needled polybenzazole (PBZ) material which is preferably polybenzoxazole (PBO), and which optionally contains a poly(1,3-phenylene isophtalamide) felt material, commercially known as Nomex™, either combined with the PBZ felt or layered beneath the PBZ felt as a separate layer. The insulation is readily applied to a reusable launch vehicle via a silicone adhesive.

Abstract: The present invention teaches systems and methods for providing a non-clumping insulating fabric suitable for use in clothing and bedding comprising: a fiber fill layer comprising a plurality of fibrous insulative elements; an adhesive layer having an adhesive surface for binding material coming in contact with the adhesive surface; wherein each insulative element of the fiber fill layer is bound to the adhesive surface forming a continues layer of secured insulative elements; repeating this layering process to reach a desired insulative value; and wherein the adhesive layer and the fiber fill layer are at least partially enclosed by a cover for preventing the fibrous elements from being dislodged from the adhesive layer and preventing the fibrous elements from being soiled.

Abstract: A buffing or polishing material has a nonwoven fleece layer and a backing layer that adds strength and dimensional stability to the material. The nonwoven fleece layer is a needled blend of natural fibers and synthetic fibers having a uniform density and working surface, resulting in a better polishing or finishing consistency. The material can withstand high heat levels and can be worked quickly, resulting in a more efficient polishing or finishing operation. The buff material can be converted into any preferred shape or tool, such as an endless belt, disc, flapwheel, or spiral band.

Abstract: Transfer belt for a paper machine, comprising a base structure (2) and a fiber batt layer (3) attached to the base structure and facing the fiber web. At least the fiber batt layer side of the belt is provided with a polymer matrix (4) impregnating the fiber batt layer (3). According to the idea of the invention, the transfer belt fiber batt layer comprises at least two fibers with different surface properties, the transfer belt surface facing the fiber web being thus provided with hydrophilic and, correspondingly, hydrophobic areas. The fibers in the fiber batt layer may differ from one another with regard to their polarity, hydrophilicity, electric charge, surface energy, friction properties, degree of fineness or porosity.

Abstract: A papermaking press felt having excellent rewetting suppression without impaired water-squeezing capability. comprises a base body, batt layers, and a rewetting prevention layer, integrated with one another by needle punching. The rewetting prevention layer has three dimensional passages comprising a verge opening, a wet paper web side opening and a roll side opening. The wet paper web side opening is larger than the roll side opening. Under nip pressure, water from the wet paper web moves into the roll surface side of the felt, passing through the passages in the rewetting prevention layer. Although a rewetting phenomenon tends to occur when the press felt is released from the nip pressure, movement of water through the passages back to the wet paper web side of the felt is suppressed since the roll side openings are narrower than the wet paper web side opening.

Abstract: A wet web transfer belt for a closed draw papermaking machine is provided with a rough surface to allow easy release of a wet web. The rough surface is obtained easily, and with reliable quality, by forming the web-contacting side of a batt layer from a welded layer of meltable fiber. A filler is included in the surface portion of the welded layer, extending from the surface at least part way into the welded layer, thereby facilitating the production of projections and concavities which provide the rough surface, and resulting in a wet web transfer belt of stable quality.

Abstract: A fire blocking material is disclosed comprising a nonwoven fabric including para-aramid fibers and pre-oxidized polyacrylonitrile, and optionally, a garnett of recycled polybenzimidazole, para-aramid or meta-aramid, or combinations thereof to form a fire blocking textile meeting Federal Aviation Administration regulation FAR 25.853 and Appendix F to Part 25.

Abstract: The invention relates to a method of manufacturing a press felt, according to which method a press felt is manufactured which has a good initial density by means a water soluble material, such as polymer, preferably polyvinyl alcohol (PVAL), applied to the texture of the press felt. Furthermore, the invention relates to a press felt comprising a body (2) and a crill layer (1) arranged thereto. Furthermore, the press felt comprises a portion of a water soluble material, such as water soluble polymer, arranged to dissolve from the texture after the initial density obtained by means of it is no longer needed.
