  • Publication number: 20220364272
    Abstract: Fabrics comprising regenerated cellulose fibers and a nanoparticle dispersed throughout the fabric are disclosed herein. The regenerated cellulose fibers can be derived from a biomass such as a fibrous cellulose, wood pulp, cotton, paper, bast fiber, bagasse, or a combination thereof. The nanoparticle included in the fabric can be chosen to confer a desirable property, such as a thermal insulating property, to the fabric. Methods of making the fabrics comprising the regenerated cellulose fibers and nanoparticle are also provided. The method can include (a) at least partially dissolving a cellulose substrate in a medium comprising one or more ionic liquids; and dissolving or suspending a nanoparticle in the medium; (b) recovering a solid nanoparticle-modified regenerated cellulose material comprising the cellulose substrate and the nanoparticle; and (c) processing the solid nanoparticle-modified regenerated cellulose material to form the fabric.

  • Publication number: 20130333346
    Abstract: A rope structure of the present invention comprises a plurality of first yarns and a plurality of second yarns. The first yarns are formed of at least one material selected from the group of materials comprising HMPE, LCP, Aramids, and PBO, have a breaking elongation of approximately 2%-5%, and have a tenacity of approximately 25-45 gpd. The second yarns are formed of at least one material selected from the group of materials comprising polyolefin, polyethylene, polypropylene, and blends or copolymers of the two, have a breaking elongation of approximately 2%-12%, and have a tenacity of approximately 6-22 gpd. The first and second yarns are combined to form rope sub-components. The rope sub-components comprise approximately 20-80% by weight of the first yarns.

  • Publication number: 20080282511
    Abstract: A termination assembly for a composite rope structure comprising an end comprises a distal connection member and a proximal connection member. The distal connection member defines a first threaded surface and a working portion, where the working portion is adapted to be connected to a structure. The proximal connection member defines a second threaded surface, an internal surface, and a proximal opening. The first and second threaded surfaces are configured to engage each other to detachably attach the distal connection member and the proximal connection member. The internal surface of the proximal connection member is configured to engage the end of the composite rope structure to secure the composite rope structure relative to the proximal connection member.
