    摘要： An aqueous starch-oil sizing composition is provided which produces improved processibility in woven and non-woven applications. The sizing has low viscosity starch, a lubricant which is a mixture of oil and wax where the wax is present in an amount of at least twice the oil, cationic lubricants, and a humectant. The size also includes an organo-functional silane coupling agent such as gamma-glycidoxypropyltrimethoxy silane which may be hydrolyzed. Emulsifiers, defoamers, and biocides may be present. Strands of glass fiber which have been treated with this size have generally shown a reduced tendency to shed the size from the strands, a reduction in the buildup of broken filaments or "fuzz" on processing equipment and reduced strand breakage.

    摘要： A wet and dry jet wet spinning process produce one or a plurality of siliceous-containing fibers. At least a partial hydrolyzate is formed from silicon alkoxides and/or colloidal dispersions of hydrolyzable metal oxides through acid catalyzed hydrolysis in the presence of a solvent. The ratio of amounts of the water to silicon alkoxide or hydrous oxide is around 1.5 to 1 up to less than around 4 to 1. Both the hydrolysis and polymerization reactions produce an ungelled hydrolyzate with a viscosity in the range of 70 to greater than 1000 poise. This hydrolyzate is extruded through a spinnerette into a gaseous environment for dry jet wet spinning followed by contacting with a nonsolvent liquid or directly into a nonsolvent liquid for wet spinning. The contacting with the nonsolvent liquid is for effective coagulation to produce cohesive fiber that may have some stickiness. The fiber is removed from the nonsolvent liquid where the fiber's length is continuous from the spinnerette to removal. The continuous fiber is collected when it has at least a coagulated surface to produce a predominantly nonsticky fiber. The fiber may be utilized as precursor fiber or further processed by washing and/or stretching and/or drying and/or heating for removal of water, and organic solvent and/or consolidating of the fiber.

    摘要： A sol gel reaction process for forming glassy articles involves the hydrolysis of silicon alkoxides with or without additional dispersions of hydrated silicon oxides, and polymerization including crosslinking. The present process involves forming glassy articles by the sol gel reaction route utilizes coagulation promoters having fatty acid hydrophobic moieties and hydrophilic moieties of primary, secondary, tertiary amines or quaternary ammonium compounds. The coagulation promoter catalyzes either and/or both of the hydrolysis and polymerization reactions. The coagulation promoter can be the only catalyst in forming the sol or can be used in addition to acid or basic catalyst. Additionally or alternatively, the coagulation promoter is added to a coagulation fluid to which shaped hydrolyzate is added. Afterwards the gelled shape precursor is optionally consolidated to form a precursor glass shape and optionally is consolidated to form the glassy shapes of films, coatings, beads, fibers, tubes and monolithic structures.

    摘要： Twisted bundle of glass fibers have on a substantial portion of the surface of each fiber a moisture reduced residue of an aqueous chemical treating composition (size). The size has an epoxy polymer as the major film forming polymer, at least one emulsifying agent for the epoxy polymer, at least one fiber lubricant in an effective fiber lubricating amount, at least one organofunctional metallic coupling agent in an effective coupling agent amount, polyvinylpyrrolidone, water dispersible or emulsifiable ultrahigh, high, or medium density polyethylene and water. The amount of the polyvinylpyrrolidone and polyethylene is in the range of around 1 to 15 weight percent of the nonaqueous components of the size for each of the polymers. When the bundle has less than around 400 filaments, starch is also present in an amount in the range of 0.5 to 15 weight percent of the nonaqueous components. The twisted bundle is produced by forming the fibers and chemically treating the fibers, gathering the fibers into a bundle, winding the fibers onto a package having a plurality of superimposed annular layers of bundles and conditioning the package to develop a moisture-reduced residue of the treatment, and unwinding the package in a horizontal position onto a vertical bobbin spinning about its longitudinal axis to produce a twist in the bundle. The twisted strand or yarn is suitable for coating with polymeric coatings like poly(vinyl chloride) plastisol coatings.
