Abstract:
Woven fabrics are formed from high tenacity fibers or tapes that are loosely interwoven with adhesive coated filaments, to composite articles formed therefrom, and to a continuous process for forming the composite articles.
Abstract:
Processes for preparing ultra-high molecular weight polyethylene fibers, and the fibers and articles produced therefrom. Exposed surfaces of the fibers are subjected to a treatment that enhances the surface energy at the fiber surfaces. Such treated surfaces are subsequently coated with a protective coating immediately after the treatment to increase the shelf life of the treatment. The coating comprises at least one poly(alkyl-oxide) polymer.
Abstract:
Processes for the production of high strength polyethylene tape articles from high strength ultra-high molecular weight multi-filament yarns, and to the tape articles, fabrics, laminates and impact resistant materials made therefrom.
Abstract:
Processes for preparing ultra-high molecular weight polyethylene yarns, and the yarns and articles produced therefrom. The surfaces of partially oriented yarns are subjected to a treatment that enhances the surface energy at the fiber surfaces and are coated with a protective coating immediately after the treatment to increase the shelf life of the treatment. The coated, treated yarns are then post drawn to form highly oriented yarns.
Abstract:
Processes for preparing ultra-high molecular weight polyethylene (“UHMW PE”) filaments and multi-filament yarns, and the yarns and articles produced therefrom. Each process produces UHMW PE yarns having tenacities of 45 g/denier to 60 g/denier or more at commercially viable throughput rates.

Abstract:
Dimensionally stable open woven fabrics formed from a plurality of high tenacity warp elongate bodies interwoven and bonded with a plurality of transversely disposed, high tenacity weft elongate bodies, composite articles formed therefrom, and to a continuous process for forming the composite articles.

Abstract:
Tape articles having improved properties are made from ultra-high molecular weight (UHMW) multi-filament yarns. The tape articles can have a ratio of the low temperature area under the curve (120° C. to Tm-onset) to the total area under the curve (120° C. to 165° C.) of less than about 0.15 as calculated from an increasing temperature DSC scan from a temperature of 30° C. to a temperature of 200° C. at a constant rate of 10° C. per minute. Additionally, in some examples the tape articles can also have a tenacity at least about 24 g/d (2.06 GPa) when measured by ASTM D882-09 at a 10 inch (25.4 cm) gauge length and at an extension rate of 100%/min. Further, the tape articles can have no long period of less than 450 Angstroms (Å) when measured by small angle x-ray analysis.
