摘要:
A woven fabric useful in protective apparel made from yarn components comprising a body fabric yarn component and a cut resistant ripstop yarn component having at least 50% greater tensile strength than the body fabric yarn component and comprising a yarn having a synthetic staple-fiber sheath and inorganic core, the body fabric yarn component and the cut resistant ripstop yarn component both being comprised of at least one yarn and each yarn component distinguished from the adjacent yarn component by interweaving orthogonal yarn components.

An antimicrobial material comprising at least one yarn comprising fine fiber of 1.0 denier or less and at least one yarn comprising antimicrobial fiber that are engaged with each other, wherein the antimicrobial fibers impart an antimicrobial property to the entire material. In a preferred embodiment, the yarns of fine fiber and yarns of antimicrobial fiber are woven or knitted together. It is further preferred that the fine fiber be less than 0.3 denier, have a diameter of approximately 3 microns, and have a generally triangular cross-section with sharp edges, therefore allowing the fine fiber to substantially remove bacteria, fungi and other microbes from a surface. It is also preferred that the antimicrobial fibers comprise an acetate fiber spun together with polyester to give the antimicrobial fiber added strength.

A carbon fiber-made reinforcing woven fabric comprising a carbon-fiber woven fabric formed from warps consisting of carbon fibers and wefts consisting of carbon fibers, and auxiliary yarns arranged along at least either warps or wefts, the auxiliary yarns being passed over and under other yarns differently from associated warps or wefts. When prepreg is produced by applying matrix resin to this woven fabric by a wet/prepreg processing method before drying, the presence of auxiliary yarns in gaps in the vicinities of warp-weft intersections on the woven fabric allows matrix resin to remain around auxiliary yarns to produce no apertures in the obtained prepreg, whereby the woven fabric is suitable for a prepreg production by wet/prepreg processing.

The invention concerns a wide-meshed woven grid (1), in particular a geotextile grid, comprising warp yarn bundles (3) consisting of several warp yarns (2) and weft yarn bundles (5) consisting of several weft yarns (4) mutually intersecting and forming grid meshes or openings (6). The invention aims at providing a larger volume to said woven grid, which can also be in the form of a wire structure for, among other things, ensuring better reinforcement of the ground. Therefor, individual wires (2 or 4) of a bundle of wires (3 or 5) constituting one mesh (6) are longer than other wires of the same bundle of wires (3 or 5). Said longer wires (4') extend in undulating manner and form in each mesh (6) at least one bulge (7) or open loop capable of projecting upwards and/or downwards relative to the plane of the woven grid (1). Said woven grid (1) can be rigidified by means of a plastic coating

A papermaking belt for use in making hard grades of paper such as printing kraft, newsprint, linerboard, fine or writing grades of paper. The papermaking belt may be used in conjunction with a single-wire draw or twin-wire draw of a papermaking machine. The papermaking belt comprises a woven reinforcing element and a patterned framework. The framework defines either or both faces of the papermaking belt. The pattern of the framework is independent of the weave of the reinforcing element. This arrangement decouples the amount and pattern of the paper-contacting surfaces of the belt from the weave and/or permeability of the belt. Further, this arrangement allows for increased and more uniform contact area of the paper web against a drying cylinder. Additionally, this belt provides an increased wear surface for improved belt life.

The present invention relates to carbon-matrix composites, such as carbon-carbon composites, and a method for forming them by forming a fabric of fusible and infusible fibers which can be processed and carbonized to form a composite. The methods disclosed herein permit preparation of composites which are particularly thin, uniform, and highly pure. The invention also relates to preprocessed fabrics and precarbonized composites, such as those comprising carbon or oxidized polyacrylonitrile fibers and fusible polyacrylonitrile fibers.

A papermaking belt comprises a reinforcing element (50) and a resinous framework (300) joined together. The resinous framework is formed by a plurality of resinous beads (110) which mutually contact or cross-over. Super-knuckles (160) extending outwardly from the reinforcing element are formed at points of contact. A preferred continuous process for making the belt comprises extruding, in a pre-selected pattern, a plurality of beads of a resinous material onto the forming surface thereby forming the resinous framework thereon, joining the resinous framework and the reinforcing element together, and then solidifying the resinous framework. The resinous material may comprise at least two chemically-active materials capable of cross-linking upon contact.

The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes 'nicking' the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the 'nicking' of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.
摘要:
Ein Drucktuch zur Verwendung auf Druckzylindern für insbesondere Offset-Druckmaschinen, mit einer inneren, bei Einsatz des Drucktuches dem Druckzylinder zugewandten Trägerschicht (4), einer mikroporösen, kompressiblen Elastomer-Zwischenschicht (3) und einer äußeren Druckschicht (1) soll dahingehend weiterentwickelt werden, dass die auf das Drucktuch während des Druckvorganges einwirkenden Kräfte nicht zu erhöhten Spannungen in gefährdeten Bereichen des Drucktuches führen. Erfindungsgemäß ist hierfür die innere, bei Einsatz des Drucktuches dem Druckzylinder zugewandte Trägerschicht als Metallschicht (4) in der Art eines biegsamen, der Krümmung des Druckzylinders anpassbaren Metallblechs ausgebildet, das zur angrenzenden Schicht über einen Haftvermittler (5) in Verbindung steht. Des weiteren wird ein Verfahren zur Herstellung eines solchen Drucktuches vorgestellt.
