Abstract: A flat woven pin-seamed papermakers fabric wherein machine direction yarns define a series of orthogonal seaming loops on the opposing fabric ends. The fabric comprises a system of flat monofilament machine direction warp yarns (hereinafter MD yarns) which are woven in a selected weave construction. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. End segments of the lower MD yarns are removed and the upper MD yarn ends are looped back upon themselves and rewoven into the fabric end in the space vacated by the trimmed lower MD yarn end segments. Non-loop forming upper MD yarns are also preferably backwoven into the space vacated by trimming the respective lower MD yarns. Preferably, at least the upper MD yarns are woven contiguous with each other to lock in the machine direction alignment of the stacking pairs of MD yarns and the orthogonal orientation of the end loops.

Abstract: A papermakers fabric having a stacked system of flat monofilament machine direction yarns (hereinafter MD yarns) which define the surface characteristics of the fabric. The system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. The upper MD yarns may be comprised of one type of material, such as nylon 6, 6 to define a hydrolysis resistance paper carrying surface with the lower MD yarns, which define the machine side surface, being made of a polyester (PET) yarns, which are lower in cost and are less hydrolysis resistant. Cross machine direction yarns (hereinafter CMD yarns) may be a third type of yarn, for example a relatively inert material such as Ryton.TM.. The CMD yarns are protected from abrasive wear by the upper and lower MD yarns.

In the preferred embodiment, the same type and size yarns are used throughout the machine direction yarn system.

Abstract: A papermakers fabric have a system of flat monofilament machine direction yarns (hereinafter MD yarns). The system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in vertically stacked orientation with a lower MD yarn. At least the upper MD yarns are flat monofilament yarns woven contiguous with each other to define a warp fill of at least 80% to reduce the permeability of the fabric and to lock in the machine direction alignment of the stacking pairs of MD yarns. The stacked, contiguous woven machine direction system provides stability and permits the MD yarns to have a relatively high aspect ratio, cross-sectional width to height, of greater than 3:1. A seam for the fabric comprised of loops formed from selected flat MD yarns is provided to render the fabric endless during use in papermaking.

Abstract: The present invention is directed to a papermakers fabric which provides for usage of high aspect ratio yarns as structured weave components. The fabric comprises a system of flat monofilament machine direction yarns (hereinafter MD yarns) which are woven in a selected weave construction which provides stability to the fabric. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. The lower MD yarns may weave in an inverted image of the upper MD yarns to provide floats on the bottom fabric surface or may weave with a different repeat to provide a different surface on the bottom of the fabric.

Abstract: A polyurethane-quartz laminate suitable for aircraft radomes. Controlled amounts of a mixture of unpolymerized 4,4 diphenyl methane diisocyanate (MDI) and 2,4 toluene diisocyanate (TDI) are polymerized with ethylene glycol at a preselected temperatures and periods to produce a polymeric resin of relatively few nonpolar isocyanate groups. The resin is impregnated and cured in layers of quartz cloth to form a relatively high strength composite or laminate having a low dielectric constant.
