Abstract: Nonwoven material produced by hydroentangling a fiber web, comprising recycled fibers with a fiber length of between 5 and 60 mm and a fineness of between 0.1 and 20 dtex, which are constituted by fibers which are mechanically shredded or torn from nonwoven waste, textile waste or the like. The fibers are mixed with each other and possibly with new fibers in a wet-formed, foam-formed, air-laid or dry-laid fiber web which is hydroentangled with sufficient energy for forming a compact absorbent material.

Abstract: A reinforced pultrusion product comprises a polymeric matrix, at least one longitudinally oriented buckled reinforcement fiber embedded in said polymeric matrix, and at least one longitudinally oriented linear reinforcement fiber embedded in said polymeric matrix. The product is formed through a pultrusion process wherein a set of composite strands comprising reinforcement fibers and polymeric fibers are provided. A supplemental tension force is applied to a first subset of the composite strands. The composite strands are heated such that the polymeric fibers of a second subset of composite strands shrink to cause the reinforcement fibers in each of the second subset of composite strands to buckle. The heated set of composite strands, including the buckled reinforcement fibers, are consolidated in a pultrusion die.

Abstract: A polymeric-resin-coated papermaking-processing belt, which may be used as a sheet-transfer, long nip press (LNP) or calender belt, includes a reinforcing base having the form of an endless loop with a face side and a back side, these being the outside and inside of the endless loop, respectively. The face side of the reinforcing base is coated with a polymeric resin material, while the back side has a staple fiber batt attached thereto. The staple fiber batt has a smooth, fused surface free of protruding fiber ends. This surface is kept clean more easily than that of a typical staple fiber batt. Methods for manufacturing the polymeric-resin-coated papermaking-processing belt, including several ways for providing the staple fiber batt with the smooth, fused surface, are also disclosed.

Abstract: Disclosed is a fabric which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The fabric is formed from a plurality of fibers which define at least one microporous passageway which allows communication, through the fabric, between its respective first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the fabric via such a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it. Passage of the microbe through the fabric is thereby prohibited. Laminates of the fabric with other materials are also disclosed.

Abstract: A calender belt for the compliant calendering of a paper web includes an endless base substrate, a staple fiber batt attached to at least the outside of the endless base substrate, and a polymeric resin material totally impregnating the fiber/base composite structure comprising the endless base substrate and the staple fiber batt to a substantially uniform depth. That depth may be such that the polymeric resin material does not reach the base substrate, or partly or completely impregnates the base substrate. A layer of polymeric resin material is built up upon the staple fiber material to a predetermined thickness. Once the polymeric resin material is cured, it is ground to a desired smoothness without exposing any fiber on the ground surface.

Abstract: A heat-sensitive stencil sheet comprises a fibrous support of polyester fibers, and a polyester film, wherein both the orientation parameter (R1) of the film and the orientation parameter (R2) of the fibers respectively obtained by laser Raman spectrometry are in a range from 3 to 10. A method for manufacturing such a heat-sensitive stencil sheet comprises thermally bonding an undrawn polyester film and a fibrous support of undrawn polyester fibers to form a laminate and then stretching the laminate, wherein, during the bonding or during the stretching, the film and the fibrous support of the laminate are heated at different temperatures, respectively.

Abstract: A hybrid CMC laminate is comprised of alternating layers of dense ceramics and fiber reinforced CMCs. The strategy involves the use of strong and stiff ceramics in order to delay the onset of cracking within the CMC layers. To provide protection from mechanical abrasion, improve thermal conductivity and inhibit oxygen ingress into the CMC layer, ceramic layers are placed on the outer surfaces of laminate. The laminate is produced by stacking alternating layers of dense ceramic and binderless layers of fiber reinforced CMCs, and then hot-pressing them together. The volume fractions of the constituent layers and the fiber architecture can be readily varied through this process. Reinforcement architecture (unidirectional vs. crossply) and the relative volume fractions of the phases effects the tensile and flexural properties of the laminates.
